Are your medical priorities straight?

The world is asunder. As I write this, Iraq is sinking into a sectarian abyss. ISIS, a terrorist group, now controls a larger territory than many actual countries. Russia has swallowed Crimea and has her paw prints all over eastern Ukraine. China is claiming airspace and territories in Southeast Asia increasing tensions with Japan, Vietnam and the Philippines. The Israeli-Palestinian peace process is in another deep freeze. Terrorists in Sudan and Nigeria are kidnapping and murdering innocents with impunity. The Syrian regime has resulted in 160,000 deaths and has displaced over 6 million people. The Taliban continue to destabilize and terrorize in Afghanistan and Pakistan. Disease and hunger claim millions of lives in the developing world while other world regions have a surplus of food and medicine. We have an immigration crisis in this country that gets worse by the day. Several million Americans are still out of work.

Let’s not be distracted by these trifles. A looming apocalypse exists that dwarfs the above issues and demands our overriding attention: Should the Washington Redskins change their name?

Sometimes, folks have difficulty deciding what’s important.

Assigning rational priorities is an important professional and life skill. Collectively, we all waste an incalculable amount of time, energy and resources pursuing ventures that should be left for another day. All of us do this. Sometimes, we do so deliberately when a lower priority activity will deliver some pleasure or entertainment. In these instances, at least we are aware that we are dipping down on our priority list.

An important physician skill is to judge which medical issues and tests should have a priority status. Hmmm, a patient suffering a heart attack also has athlete’s foot. Which issue do I address first? We would recognize that a patient recovering from a severe pneumonia in an intensive care unit should not undergo a mammogram or a screening colonoscopy. Often, it is not so easy to determine the medical priorities and different physician specialists on the case may disagree on what should be the next step.

Here are a few hypothetical scenarios.

A surgeon insists that an operation is urgently required, but the cardiologist counters that stabilizing the patient’s congestive heart failure must be done first.

A gastroenterologist advises stopping a blood thinner as the patient has a bleeding ulcer, while the pulmonologist disagrees as the patient has a new pulmonary embolus and argues that the blood thinner cannot be interrupted.

A patient comes to his internist very anxious over 3 days of rectal bleeding. He wants a colonoscopy as soon as possible as his father had colon cancer. The physician advises instead evaluating the patient’s recent episodes of chest tightness, which the patient dismisses as anxiety.

Knowing how to do something well is not nearly as important as knowing if and when it should be done at all. Who wants to have his gallbladder flawlessly removed if it didn’t need to come out? You can substitute any surgery, medical procedure, diagnostic test or treatment in this example.

Medical knowledge is important. Technical procedural proficiency is necessary. Communication skills are a distinguishing asset. But, medical judgment is paramount.

Oh, what to do about that background hospital beeping?!

You enter a patient’s room, begin a conversation, and then hear it. It may be from your patient’s machine, or the next bed; from the intravenous infusion or the telemetry monitor.

“Beep, beep, beep!”

What do you do? Do you:

A. Look into the situation yourself and work out what’s wrong?

B. Try to silence the alarm immediately?

C. Call the nurse to look into it?

D. Just let the machine keep beeping for now and carry on your conversation?

Which one you usually do probably depends on the clinical situation and what type of machine the alert is coming from. Obviously an emergency telemetry monitor alarm will provoke an immediate response. However, all hospital medicine doctors will be familiar with the above everyday scenario. More often than not, it’s a simple issue with the IV machine, such as an occluded line or an alert that the infusion has finished.

Interestingly, on occasions where people have shadowed me at work—from both clinical and non-clinical backgrounds—I’ve often heard them remark about all the background noise we hear from the machines on the floors. They also frequently ask me what certain alerts mean, and I must admit I’m not always sure without looking in detail at the machines! The volumes and types of alarms can make hospitals very noisy and confusing places. You wouldn’t have the same situation say on an airplane, hearing alerts that aren’t immediately understood and addressed by the pilot or cabin crew. Quite simply, there are far too many background alarms in the hospital environment. In fact, this phenomenon of “alarm fatigue” probably affects hospital medicine doctors more than any other specialty, because we spend the most time on the hospital floors.

And even though most of us have just accepted it as the norm of being in a hospital environment, the issue is finally getting the attention it deserves. The data is truly alarming (no pun intended). One national survey from earlier this year showed that 19 of 20 hospitals ranked alarm fatigue as a top patient safety concern. Statistics frequently cite the number of alarms at up to several hundred per day for some patients. There have even been some well-documented cases in the media of harm resulting to patients when alerts are ignored. As a result of this increased awareness, the Joint Commission recently rated the problem as a National Patient Safety Goal and is requiring hospitals to take steps to address the issue.

It’s easy sometimes for physicians to think about the alarm as a “nurses problem,” but it really isn’t. The issue requires high level thought, because who decides what is or isn’t a necessary alert and is it right that the nurse is typically responsible for adjusting the alarm settings?

Aside from the safety issue, there’s also another elephant in the room. How often have you walked in to see a patient and heard them immediately complain about the fact that their machine has been beeping for a long time and it’s been bothering them? The nurse may have understandably been busy with something else and not gotten to it yet. It can be a big barrier to patient satisfaction and allowing our patients to get a decent rest.

In terms of dealing with the alarm fatigue problem, there are a number of potential solutions. Some institutions such as Boston Medical Center have successfully led initiatives by changing the settings of alert systems, such as those related to non-emergent bradycardia. In the future, different machines could even be designed, quieter for non-urgent alerts, or utilizing built-in systems that automatically page the nurse instead with certain issues such as an occluded IV line. The final option is to just keep the status quo, accepting that hospitals are places that must always have background alarms because of the nature of the work.

There’s no easy answer, but do give it some more thought next time you’re with a patient and hear that beeping …

Guidelines should rarely become rules

The blog FiveThirtyEight has this wonderful provocative article, ”Patients Can Face Grave Risks When Doctors Stick to the Rules Too Much.”

The subsequent comments have debates over the value of guidelines. Guidelines are like a box of chocolate, you never know what you are going to get. Many clinical questions yield “competing guidelines.” We all know the controversies over breast cancer screening and prostate cancer screening. Recently BP targets and lipid management have become controversial. Pharyngitis (a personal research interest) has multiple varied guidelines.

In the movie Pirates of the Caribbean, this classic exchange makes the point:

Elizabeth: Wait! You have to take me to shore. According to the Code of the Order of the Brethren …

Barbossa: First, your return to shore was not part of our negotiations nor our agreement so I must do nothing. And secondly, you must be a pirate for the pirate’s code to apply and you’re not. And thirdly, the code is more what you’d call “guidelines” than actual rules. Welcome aboard the Black Pearl, Miss Turner.

What is the problem? As one of my heroes said many times, everything in medicine requires context. We have differing opinions on the importance of that context.

Given that I have studied the pharyngitis problem for many years, let me use that as my example.

You are a primary care physician seeing an adolescent with pharyngitis. You have 2 concerns, helping the patient feel better and decreasing the probability of complications, either suppurative or non-suppurative.

Now imagine you are an infectious disease expert. You rarely see pharyngitis patients, but you are worried constantly about antibiotic resistance. Your concern centers on the “overuse” of antibiotics.

You can imagine how these two incarnations of you would view the problem differently. The first you is patient focused; the second you takes a public health viewpoint. Who is correct?

Actually, neither is correct and neither is wrong. The two versions of you have differing context.

Since both views have validity if one agrees with the context, developing a context free rule based on one of these guidelines would constitute a potential error.

The danger of rules (I hope you are reading performance measurement here) comes when they discount context. Some rules have resulted in patient harm.

When insurance companies judge, and even reward, physicians for meeting rule targets, some physicians will overlook context.

This Medscape article about hypoglycemia in the elderly raises important issues about HbA1c targets. Hypoglycemia a Greater Threat Than Hyperglycemia in Elderly.

Performance measures are rampant, primarily because the “suits” believe that we can use them to measure quality. I am proud that the ACP performance measurement committee carefully evaluates many measures. Often these proposed measures get a thumbs down. ACP Performance Measure Recommendations

We need a more widespread accountability on performance measures. The ACP committee careful evaluates the context of proposed measures. Why do other organizations not adopt this enlightened approach?

QD: News Every Day--Drugs that raise HDL didn't reduce cardio events, mortality

Niacin, fibrates, and cholesterol ester transfer protein (CTEP) inhibitors may have raised HDL levels, but they showed no effect on all-cause mortality, coronary heart disease mortality, non-fatal myocardial infarction, and stroke, a meta-analysis concluded.

Researchers reviewed 39 randomized trials of more than 117,000 patients receiving drugs that raise HDL levels. The meta-analysis appeared at BMJ.

No significant effects were seen for:
• all-cause mortality: niacin (odds ratio [OR], 1.03; 95% CI, 0.92 to 1.15, P=0.59), fibrates (OR, 0.98; 95% CI, 0.89 to 1.08, P=0.66), or CETP inhibitors (OR, 1.16; 95% CI, 0.93 to 1.44, P=0.19);
• coronary heart disease mortality; niacin (OR, 0.93; 95% CI, 0.76 to 1.12, P=0.44), fibrates (OR, 0.92; 95% CI, 0.81 to 1.04, P=0.19), or CETP inhibitors (OR, 1.00; 95% CI, 0.80 to 1.24, P=0.99);
• stroke: niacin (OR, 0.96; 95% CI, 0.75 to 1.22, P=0.72), fibrates (OR, 1.01; 95% CI, 0.90 to 1.13, P=0.84), or CETP inhibitors (OR, 1.14; 95% CI, 0.90 to 1.45, P=0.29).

Before the statin era, niacin was associated with a significant reduction in non-fatal myocardial infarction (OR, 0.69; 95% CI, 0.56 to 0.85, P=0.0004) compared to having no effect in patients taking statins (OR, 0.96; 95% CI, 0.85 to 1.09, P=0.52) (P=0.007 for difference).

There was a similar trend for fibrates and non-fatal myocardial infarction for patients before the statin era (OR, 0.78; 95% CI, 0.71 to 0.86, P<0.001) and after (OR, 0.83; 95% CI, 0.69 to 1.01, P=0.07) (P=0.58 for difference).

The authors wrote, “Although observational studies might suggest a simplistic hypothesis for high density lipoprotein cholesterol, that increasing the levels pharmacologically would generally reduce cardiovascular events, in the current era of widespread use of statins in dyslipidemia, substantial trials of these 3 agents do not support this concept.”

The study follows another report that niacin did not significantly reduce vascular events and did cause a variety of serious side effects for high-risk patients.

In case you missed it …

Don't let summer bites make you sick

The Polar Vortex that kept so many of us indoors for months has finally retreated. This can only mean 1 thing: mosquito season. As humans spend more time outside, they are exposed to illness carried by mosquitoes and ticks and there are some not-so-fun new ones to learn about. First the oldies but goodies.

Lyme disease is the best-known tick-borne disease in the U.S. It is endemic to the Northeast, parts of the Upper Midwest, and some parts of the Pacific Northwest. It causes a characteristic “bulleye” rash called erythema migrans, and if untreated can lead to fever, joint pains, and occasionally more serious symptoms. It is very easily treated with antibiotics. Despite the hype coming from some patients and doctors, once Lyme is treated it is cured. There is no such thing as “chronic Lyme disease”.

Mosquito bites are a lot more common than tick bites and can cause some remarkably horrid diseases. The worst of these is malaria which kills about 627,000 people every year around the world. Thankfully, it’s quite rare in the U.S. (but it wasn’t always). The biggest risk to Americans is with travel to endemic areas. Malaria classically causes very high relapsing fevers, and any fevers after travel to a malarial area should be evaluated by a doctor.

Gaining a larger foothold in North America is Dengue fever, also known as “breakbone fever” for the tremendous pain it causes.

Dengue is uncommon in the continental US, but is very common in the Caribbean, including Puerto Rico. It causes fever and tremendous joint and muscle pain, but usually no lasting damage. It is generally confined to tropical and sub-tropical regions, but global travel and climate change are putting the continental US at greater risk. In 2009 there was an outbreak in Key West, Fla. that was not imported from abroad.

The latest player, and the one with the best name, is chikungunya. This mosquito-borne virus has recently made its way to the western hemisphere and is becoming a significant problem in the Caribbean. So far there haven’t been an cases transmitted within the continental U.S., but this could easily change as travelers have returned with the disease, and there are native mosquitoes that can carry it. “Chick” is very much like dengue, the name coming from a Makonde word meaning “it bends up”, presumably referring to the contortions of pain suffered by its victims.

The good news is that all of these diseases are preventable. Public health measures can eliminate or treat standing water where mosquitoes breed, and individuals can cover up, use DEET-based insect repellent, and limit exposed skin, especially at dawn and dusk when many mosquitoes prefer to feed. (Ticks are a bit trickier, but they can’t bite through clothes, so tuck in those pant-legs).

Your risk of getting a bug-borne illness in the U.S. is still quite low, but if you want to avoid ruining your day, check your local health department’s website for updates on nearby outbreaks and prevention measures.

Fat: ending the war that nobody started

Given the timing, it is more than a little ironic that the current Time magazine cover story is about an alleged war that has been raging for a long time; about questionable motives and dubious intelligence; about the failure to find what we went after in the first place; and about a whole lot of questions and chaos in the aftermath—yet is has nothing to do with Iraq. As noted, truly ironic.

The current Time magazine cover story refers to ending the war on dietary fat. And overall, writer Bryan Walsh does a good job of war reporting, addressing all fronts of this now decades-long conflict in the span of just a few pages.

As you might expect, though—I am left with some concerns. When it comes to diet, we seem more prone to the crude influence of inertia than a block of flotsam floating through space—and all but immune to the subtleties of actual thinking. Since the current momentum is aimed at a condemnation of the so-called ‘war’ against fat, this article may simply feed into it—and encourage people to feed themselves ever more baloney (and related deli meats). This despite the ongoing parade of studies highlighting the hazards of doing just that.

I also worry that the majority of readers won’t get past the title and cover image, since the majority of readers never do. Most, I suspect, will simply decide on the basis of the buttery cover that the article means just what they want it to mean—and pass the pork chops accordingly.

Whether or not a product of good reporting, that’s bad news. We in the media are overdue to embrace the anti-intellectual realities of this sound bite, Tweet-driven world of ours and acknowledge that titles and cover images matter, as they are all many will ever see. For many—the title or headline is the punch line, not the introduction. Calling all editors: Please choose accordingly from now on!

No, folks. You should not start eating more baloney, nor meat in general, nor butter, nor cheese. We’ll get back to that war in a moment, but for now, here are four important considerations for you:

1) We have been eating fewer vegetables. This is an easily overlooked tidbit in Mr. Walsh’s article—it shows up in the third column of the second row of a figure about where our calorie intake went down. The figure tells us that our intake of calories from vegetables has gone down 3% since the 1970s. Since vegetables don’t have many calories—one of their many virtues—that means our intake of vegetables has gone down rather a lot. That advice to eat less meat, butter and cheese could result in reduced vegetable intake is pretty incredible. If we extend the war analogy, it would be right up there with looking around at the aftermath of the bombardment—and then realizing we had landed the troops in the wrong country altogether. Oops. Sorry, everybody!

2) We increased our calorie intake. This may not have been as diametrically opposed to the intended guidance as reducing vegetable intake—but it’s pretty darn close. Mr. Walsh devotes most of his verbiage to the particular, and competing sources of calories, but he does tell us this one line in 1 little paragraph somewhere in the middle of his piece: “The idea here was in part to cut calories, but Americans actually ended up eating more: 2,586 calories a day in 2010 compared with 2,109 a day in 1970.” We were too fat, and too often sick when the ‘war’ against dietary fat began—and that in fact is why it began, partly in an effort to help curtail our intake of excess calories, driving the obesity epidemic—and the attendant epidemics of related chronic diseases that persist to this day. Calorie intake was supposed to go down, not up. We ate more instead of less, and got fatter instead of thinner. And so again: Oops!

3) We are not clueless about the basic care and feeding of Homo sapiens. I won’t belabor that here, but will note that a recent review of relevant literature lead me to no particular epiphanies about fat, or carbohydrate, or protein; but to the conclusion that the basic theme of healthful eating is very clear to anyone willing to see it. Unfortunately, those hungering for scapegoats or silver bullets are not willing to see it—or swallow it.

4) In an entirely unrelated review of the literature on diet and diabetes, Dr. Frank Hu and colleagues reached a virtually identical conclusion to mine in #3.

But let’s get back to the war. There clearly isn’t a war against all dietary fat, and hasn’t been one for a very long time if ever. Anyone not living under a rock on another planet knows that the ‘Mediterranean diet‘ is one of the healthiest options we’ve got, and it’s awash in olive oil. Anyone not lost at sea without radio contact knows that fish oil is good for us.

But while no one ever really declared a war against dietary fat in the first place, somehow, that distorted perspective took hold. The whole thing resembles nothing so much as a game of ‘telephone,’ in which an initially intelligible message is passed through a series of whispered repetitions, until utter gibberish emerges.

An effort by scientists—whether inspired or misguided—to shift our dietary pattern away from certain foods and toward others was co-opted by food industry opportunists, and shifted toward a different, and newly invented set of foods. Then, we the people, happily eating Snackwells, did the rest—with some help from the usual suspects: media, marketers and faddists. The war we are now being encouraged to end was more of a charade than the one in the movie Wag the Dog.

But even if a war against dietary fat had ever really existed as anything more than gibberish, it would still be long over by now. Recent battles have been far more surgical in nature, although perhaps still not quite enough so. We appropriately went after trans fat. But we have tended to refer to all polyunsaturated fats as “good,” while neglecting the rather extreme and well-documented imbalance in the pro-inflammatory omega-6s and the anti-inflammatory omega-3s (an oversimplification, but useful just the same) in modern diets. We have maligned saturated fat as a class, and only late in the game are coming to realize that not all saturated fatty acids are created equal. We are still a bit stuck with the need to make them all good in order to acknowledge that they aren’t all bad. Modern nutrition seems more a product of Newton’s third law of motion than anything resembling evidence-based sense.

We have certainly had, and continue to have, baby and bathwater issues. Or, to continue the military metaphor—we have at times failed to recognize the enemy disguised as a friend, and at times have perpetrated the inadvertent harms of “friendly fire.”

Mr. Walsh is rather harsh in his characterizations of Ancel Keys, the epidemiologist who was among the first to look for explanations in cultural and dietary variations for the high and rising rate of heart disease in the U.S. But wherever you land with regard to Dr. Keys, it’s important to pause and note this: heart disease rates were high and rising when Keys started this work, and that’s why the work was started. Attempts to blame Keys and his disciples for what ails us run afoul of the fairly standard requirement that cause should precede effect.

The original advice about cutting fat—from Keys and others—was advice to eat fewer of the fat-rich foods that predominated in the then typical American diet—namely meat, butter and cheese—and replace them with more of the then-available foods naturally low in fat. Those foods were vegetables, fruits, beans and legumes, and whole grains. Had that swap ever been made, there would have been no war to wage, no war to end, and many fewer casualties along the way of chronic disease, premature death and obesity.

The intended guidance was never applied. Big Food took over the field, and completely recast the terms of engagement. Rather than eating less steak and more spinach, we passed the Snackwells. As noted, when the advice about dietary fat was first issued, Snackwells had not yet been invented.

That invention inevitably became the mother to new nutritional necessities; suddenly, we all needed low-fat snack foods. That would have been bad enough—but things got worse. Foods like Snackwells came along with propaganda: this is what was meant by ‘cut fat’ in the first place. Of course, it was not.

The ‘eat low-fat junk’ phenomenon was never the product of scientific guidance. It was the result of epidemiology drowned out by economics, public health subordinated by propaganda. Madison Avenue just made it up.

And we went along; of that, we are indeed guilty. Tempted though we may be to blame everybody else, to some extent when we meet the enemy here—it is us.

Our principal transgression was gullibility. It was as if we had all been told that it’s wrong to punch one another—with the intent, clearly, that we use our words to resolve our conflicts. But then the mallet salesmen came along to tell us that what had been intended was we use hammers instead of fists. And away we went, knocking one another over the head—wondering all along why the epidemiology of head trauma never improved. It is long past time for all that hammering to knock some sense into us all.

Only 1.5% of Americans meet daily recommendations for both vegetables and fruits to this day—despite decades of trying to change these deplorable statistics. We got advice to eat less meat and ate fewer vegetables. Looking at the trends in American eating from just a bit of altitude invites nothing so much as an incredulous shake of the head, and a roll of the eyes. We seem badly in need of a war against nincompoopery.

The evidence continues to accrue—with almost surprising frequency—that we should, indeed, eat less meat, butter and cheese (before we even factor in the environmental considerations, which frankly we should do). We just shouldn’t replace them with donuts, Snackwells and soda. Well … duh. Really.

So here we are—striving to end the war that no one really declared in the first place. Certainly no one ever recommended that we reduce our intake of fatty foods, but wind up eating fewer vegetables and more calories. Courtesy of no one’s advice, but a whole lot of agendas mostly involving money—that’s what we did. We have been living, and all too often dying, on a diet of unintended consequences ever since, and are still apparently disinclined to eat more vegetables, fruits, beans, lentils, nuts, seeds and whole grains. Alas.

And now we face the prospect of more unintended consequences, as we are told it’s time to end the war. The starchy, sugary, tasty low-fat junk foods we invented to exploit the ‘low fat’ guidance are still with us, and still tasty. So I envision a peace treaty with dietary fat that is silent on the matter of wholesome foods in sensible combinations ushering in a new era of dietary debauchery: this time, we will add back meat, butter, and cheese while failing to cut much starch or sugar. It is possible to eat even fewer vegetables and more total calories, and if history is any indication—that’s just what we’ll do. That will be tragic, because the evidence for what we really should be doing is strong and clear and consistent and compelling. But it’s devoid of conspiracy theory intrigue, lacking in scapegoats, and bereft of silver bullets. It’s a non-starter in other words.

Which leads us back to where this began, the start of a war no one ever really declared, that it is now time to end.

Okay, but do have a look out at the world—Iraq in particular—and consider that how a war is ended can be at least as calamitous as how it is begun. I told you it was ironic.

QD: News Every Day--Don't use feeding tubes for advanced dementia, geriatrics society says

Feeding tubes are not recommended for older adults with advanced dementia, according to a position statement from the American Geriatrics Society. They don’t prevent complications of hand feeding, led to complications, and take away life’s simples pleasures of eating and interacting with others.

Hand feeding is at least as good as tube feeding for the outcomes of death, aspiration pneumonia, functional status, and comfort, the statement reads, and tube feeding is associated with agitation, greater use of physical and chemical restraints, tube-related complications, and development of new pressure ulcers.

The position statement appeared online July 17 at the Journal of the American Geriatrics Society.

Among the rationales:
• Survival is not better in those who are tube fed rather than hand fed;
• There’s no evidence that tube feeding prevents aspiration, heals pressure ulcers, improves nutritional status, or decreases mortality;
• Tube feeding is associated with aspirations, malfunctions, oral secretions that are difficult to manage, discomfort, use of physical and chemical restraints, and pressure ulcers;
• Nursing home residents frequently need to be transferred to the emergency department to address tube-related complications such as blockage and dislodgement; and
• Greater levels of discomfort have not been observed, despite eating difficulties.

The position statement recommended involving families about the natural progression of dementia, including eating difficulties, and acting proactively to make decisions through advance directives. It also suggested enhance oral feeding by altering the environment and creating individual-centered approaches.

“Oral feeding may be one of few remaining pleasures and a time for socialization for a person with advanced dementia,” the statement reads. “Mealtime must be regarded as an event of importance, instead of a task that needs to be completed as soon as possible.”

Stewardship effective in C. difficile prevention: a meta-analysis

As Dan Diekema, MD, FACP, mentioned last week, when 15% of asymptomatic hospitalized adults carry toxigenic strains of Clostridium difficile, it should alert us to focus on antimicrobial stewardship as a way to prevent C. difficile infections. But how effective are stewardship programs and does it matter what type of program you implement in your hospital? If only there was some sort of systematic review or meta-analysis to guide or decision making.

As if on cue, Leah Feazel and Marin Schweizer at University of Iowa published such a review and meta-analysis titled “Effect of antibiotic stewardship programmes on Clostridium difficile incidence” in Journal of Antimicrobial Chemotherapy earlier this spring. Typical of projects completed by Marin and her group, they thoroughly combed the literature for papers. Here they identified 891 articles, reviewed 78 full articles and included 16 studies in their final analysis. Over all, stewardship programs were associated with a 52% reduction in C. difficile infections incidence. Importantly, programs appeared effective when implemented in whole hospital or geriatric settings and when utilizing a persuasive approach or a restrictive approach. I’ve provided the forest plot of studies below. An additional note is that the studies utilized various quasi-experimental study designs and based on the funnel plot, there appeared to be little publication bias.

Key points: (1) Stewardship works for C. difficile infections prevention, but it would have been nice if there was at least 1 funded randomize, controlled trial or cluster-randomized, controlled trial. (2) The meta-analytic approach, that Marin has pushed through her reviews of surgical site infection bundles and hand hygiene interventions, is a fantastic way to guide medical decision making and should be considered for inclusion in future hospital acquired infection guidelines. The reality is that infection prevention studies overwhelmingly utilize quasi-experimental designs. Why not identify the highest-quality QE studies and rigorously meta-analyze them as done here?

QD: News Every Day--Young women with heart attacks face more mortality, longer hospital stays

Young women with heart attacks have more comorbidity, longer hospital stays, and higher in-hospital mortality than young men, although their mortality rates are decreasing, a study found.

To determine sex differences in clinical characteristics, hospitalization rates, length of stay, and in-hospital mortality by age group and race among young patients with acute myocardial infarctions (AMIs), researchers applied data from the National Inpatient Sample for patients with AMI across ages 30 to 54 years, dividing them into 5-year subgroups from 2001 to 2010.

Results appeared in the Journal of the American College of Cardiology.

There were more than 230,000 hospitalizations with a principal discharge diagnoses of AMI in 30- to 54-year-old patients, or nearly 1.13 million hospitalizations. Women were nearly 26% of young patients hospitalized with AMI. There were no statistically significant declines in AMI hospitalization rates age groups younger than 55 years old, or when stratified by sex.

Hospitalization rates for AMI were higher in men compared with women across all age subgroups. The absolute number of discharges for AMI among women increased from 56 per 100,000 in 2001 to 61 per 100,000 in 2010. But, the absolute number of discharges for AMI among men decreased from 174 per 100,000 to 171 per 100,000. Although absolute declines were noted for most subgroups of men, women showed either no change (30 to 34 and 35 to 39 years of age) or a slight absolute increase (40 to 44 and 45 to 49 years of age) in hospitalization rates.

Women had higher in-hospital mortality than men across all subgroups. From 2001 to 2010, overall observed in-hospital mortality for women with AMIs declined from 3.3% to 2.3%, (a 30.6% decrease; P for trend<0.0001). For men, the decrease for men was from 2% to 1.8%, (an 8.5% decrease; P for trend=0.6).

Authors noted that the results suggest a greater need for intensive primary prevention efforts in the high-risk young population, and that young women may gain more benefit from aggressive control of cardiovascular risk factors such as hypertension, hyperlipidemia, obesity, smoking, and diabetes.

An editorial stated that persistent excess mortality among young women emphasizes the ineffectiveness of current practices and the need for sex-specific research and guideline development. “It remains vital that sex-specific differences in guidelines constitute more than 1 page of our large guideline documents.”

Medical 'reversals'

Twenty-five years ago, the New England Journal of Medicine issued a report on a stunning new medical discovery: Aspirin helps prevent heart attacks.

Yes, good ol’ aspirin. Known since the time of Hippocrates for its magical abilities to quell fever and pain, it took only 2000 years for us to understand the science of it well enough to design a ’sufficiently powered’ double-blind, placebo-controlled randomized trial on aspirin’s efficacy in preventing heart attacks. The Physicians’ Health Study, so named because the study subjects were randomly selected physicians from across the U.S. (whom it was correctly assumed would have higher adherence in swallowing daily pills), addressed the question of whether or not aspirin has true live-saving benefit.

It does. Citing aspirin’s “extreme beneficial effects on non-fatal and fatal myocardial infarction”—doctor speak for heart attacks–the study’s Data Monitoring Board recommended terminating the aspirin portion of the study early (the study also looked at the effects of beta-carotene). In other words, the benefit in preventing heart attacks was so clear at 5 years instead of the planned 12 years of study that it was deemed unethical to continue blinding participants or using placebo.

Confusingly, there is now strong evidence that what’s beneficial for hearts can be harmful in eyes: older people who routinely take aspirin are nearly three times as likely to develop macular degeneration than non-users. Macular degeneration is the leading cause of blindness in Americans 55 and older. It presents a vexing medical problem, in that once it’s discovered, it’s too late to do anything about it. Macular degeneration afflicts more than ten million people in the U.S., which is likely an underestimate of its true prevalence.

What we see in this situation is a classic story arc in modern American medicine: Wonder-drug saves lives. Study stopped. Practice adopted. Then, years later: wonder-drug causes harm. Edicts to stop prescribing it, or be much more selective about recommending it.

Adam Cifu, a doctor (and former colleague) at the University of Chicago, has written about the concept of “reversals” in medicine. In a fascinating paper, Cifu and colleagues catalogued several examples of new knowledge leading to “abandonment” of mainstream medical practices. A major example is hormone replacement therapy for post-menopausal women. For decades estrogen was given to American women as an elixir for many ills. All of the data in support of the practice was observational; outcomes conformed neatly to expectations about the drug. When good science (a randomized, controlled trial called the Women’s Health Initiative) finally challenged the practice, it was almost entirely abandoned.

I asked Cifu for a prediction about the near-blanket recommendation to people of a certain age to take aspirin, which is prescribed so widely, including to many who do not actually have heart disease or elevated cardiovascular risk. In an email, he wrote: The [Physicians’ Health Study] never showed mortality benefits but only benefit to lesser outcomes such as [heart attack]. Even in the earliest studies there was evidence that the benefit was only in limited populations, older ones, and was balanced by significant risk of bleeding (GI [stomach, etc.] and CNS [brain]). I think what has happened is that as the scope of the trials have expanded in terms of both patients and endpoints, we have gotten a more nuanced view. Certainly the idea that [not] everyone over 40 should be on aspirin is a reversal but we will probably always be giving prophylactic [aspirin] to a subset of patients.

Got that?

One thing seems to be sure in medicine: if we just wait long enough for excellent science to guide us ahead, things we trust as ironclad rules often change.

Is my medicine on the prescription drug formulary?

One of the frustrating aspects of medical practice is trying to divine if the medication I am prescribing is covered by the patient’s insurance company. Even with the advent of electronic medical records, which should be able to determine this, we are often left to hope and pray.

Here’s how it works. Individual insurance companies have formularies, lists of approved drugs, that they encourage patients and their physicians to use. Of course, this is all about the money. There’s nothing evil about an insurance company making a deal with a particular drug company that gives them a price break. The drug company will be delighted to offer the insurance company a discount in return for an anticipated high volume of prescriptions. You can easily picture an insurance company negotiating with several different GERD medication representatives watching them each lowering their bid trying to get the contract.

Nexium Guy: We’ll only charge you $0.67 a pill

Prevacid Gal: We’ll only charge you $0.84 a pill and will throw in the Japanese steak knives

Protonix Guy: We’ll lower our already rock bottom price down to $0.65 a pill for an exclusive contract

Prilosec Gal: We’ll only charge $0.57 a pill for a brief term of 10 years with an option to renew

When a patient sees me for heartburn, and I recommend a medication to ease their pain, often neither the patient nor I know which of the 6 proton pump inhibitor medicines (e.g. Nexium, Prilosec, etc.) or the generics will be covered. That’s when the guessing starts. My objective, of course, is that the patient pays the least amount of money without sacrificing medical benefit. When I guess wrong, I am then welcomed by phone calls, faxes and other forms of denial that we then devote time to sort out.

Recently, I called a pharmacist with the patient seated before me to try to be a hero and figure out which medicine was the right stuff. Even the pharmacist couldn’t figure it out. She explained to me that she couldn’t price the medicine for this specific patient unless I prescribed it officially and she then processed it through. I thanked her, hung up and resorted to my default strategy. I guessed.

Keep in mind that these formularies change yearly. In other words, a medicine that’s preferred in December may be tossed aside in January when a new drug underbids them. This adds to the adventure. We have an office pool every December when we offer prizes for guessing the new medication changes. We use this changeover as an opportunity to increase staff morale.

Next time you’re in your doctor’s office, ask what a “prior auth” is.

In my practice, I might see 15 or 20 folks each week who want me to put their GERD fires out. They have different insurance plans with different formularies and different restrictions. The chance that I prescribe the preferred medicine to each of them on the first try is much lower than winning the lottery. If fact, if I were to achieve this pharmaceutical tour de force, I think I am entitled to instant wealth. Perhaps, the pharmaceutical companies would pool their resources an sponsor a contest for gastroenterologists. What a slick marketing campaign!

Prescribe Heartburn Medicines Correctly for a Week and Win a Million Dollars!

They have nothing to fear. While physicians may accept the challenge with enthusiasm, they will never succeed. They would do better buying a lottery ticket.

When a well-intentioned, authoritative 'no' is better than an insincere 'yes'

The above title may sound rather controversial at a time when patient satisfaction and improving the health care experience is a hot topic around every hospital administration table. It’s something that I’ve thought and written a lot about and also personally feel very strongly about, because nothing short of total commitment to our patients is required when they are at that low point in their lives. There’s so much room for improvement.

Unfortunately though, as hospitals grapple with the issue of how to make the health care experience a better one, some of the ideas being put forward are rather gimmicky. For instance, I’ve seen name badges saying “Have a nice day” or “What can I do to help you?”, which are probably more appropriate for an auto shop or fast-food restaurant. Physicians and nurses simply shouldn’t be wearing them! An attorney, teacher or even a banker wouldn’t dream of wearing that on their suit, so why should a doctor wear it on their white coat? We must keep our respect as a profession and remember that the main driver of patient satisfaction will be the human interaction between doctor and patient. Everything else is secondary.

There are in fact some very real differences between customer service in hospitals and customer service in other arenas. The mantra in the business world that “the customer is always right” does not hold true for many scenarios in health care, when the patient doesn’t know what’s best for them. This is not meant to sound paternalistic, because patient-centered care is the right way forward, but there are definite limits and boundaries in health care. Making informed choices, yes. Being in charge of their own health care, yes. But the reality is that doctors often do know what’s best based on their professional knowledge. Examples include prescribing the most appropriate medication, recommending a certain type of surgery, and not being over-zealous with pain medications, despite the patient’s wishes. In fact, not doing what they think is right may frequently lead the physician down the path of inferior patient care.

The best, and for that matter most popular, physicians that I’ve observed have actually been far from “customer service” types. Not that they don’t strive to go the extra mile for their patients and provide the best possible care, but they also balance their compassion with a strong personality and strong principles too. They are physicians that know when to say “no” and are not afraid of telling their patients what they need to hear and not what they want to hear. Sometimes what they say to their patients could be construed as bordering on rudeness to an outside listener, but their rapport is good enough to negate any hard feelings. I’ve encountered several dozen physicians like this, most of them the “old-school” types near retirement age, and never fail to hear positive glowing reviews from their patients who truly respect them. These are the role model doctors for me. It’s what we have to remember if we think any patient needs a “yes man” doctor to get good medical care. Patients actually respect a well-intentioned authoritative “no” rather than a smiling insincere “yes” over a long-term relationship. Indeed, in most areas of life, this is the case. It holds true for a family member, friend, or even a politician! A recent article in Forbes magazine discussed this very issue, in a piece titled Dr. House Was Right: Give Patients What They Need, Not What They Want”. The article described how patient satisfaction is tied to higher costs, and more concerning—higher mortality. It posed an interesting question between choosing between a nice doctor or a brilliant doctor. The author chooses the latter. However, the 2 don’t have to be mutually exclusive. They can be perfectly balanced. It would be a big mistake if we train the next generation of doctors to be “yes men/women” types in the fear of being seen as giving poor customer service or worried about poor patient satisfaction scores. In our relatively new internet age, when online ratings are available in a second, it’s understandably a worry for many doctors. This has turned medicine into a completely new ball-game that the older generations didn’t have to concern themselves with. Gone are the days when doctors could be safe in the knowledge that they were good at what they did and had patients flocking to them. Will the patient give me a bad review if I don’t do exactly what they want? Should I try to make my patient happy even though I know it’s not good for them?

Patients should know that it may be a mistake to seek out a doctor who pleases them, or use online recommendations to choose them. If you want to find a good doctor, nothing could be better than a solid word of mouth recommendation from a family member or friend.

New physicians should understand that their best peers aren’t necessarily the ones with the best ratings. They should be guided by their knowledge, principles, and stand firm if they believe something is right. As we endeavor to provide excellent care and a better experience, doctors shouldn’t be striving to make their patients happy at every opportunity. We should be striving to make our patients better. With a dose of compassion, empathy and sincerity—the rest will take care of itself.

QD: News Every Day--Lifestyle interventions could cut Alzheimer's by a third globally

One-third of Alzheimer’s diseases cases worldwide might be attributable to potentially modifiable risk factors such as physical inactivity, smoking, midlife hypertension, midlife obesity, diabetes, and depression, a study found

Researchers used relative risks from existing meta-analyses done from 2004 to this year to estimate the population-attributable risk of Alzheimer’s disease worldwide by accounting for the association between 7 risk factors: diabetes, midlife hypertension, midlife obesity, physical inactivity, depression, smoking, and low educational attainment. They then examined the combined effect of relative reductions of 10% and 20% per decade for each of the 7 risk factors on projections for Alzheimer’s disease cases to 2050 in order to determine the potential of risk factor reduction.

Results appeared in the August issue of The Lancet.

Worldwide, the highest estimated risk factor was low educational attainment (19.1%, 95% CI, 12.3% to 25.6%). Among Western nations, the highest estimated risk factors was physical inactivity, in the U.S. (21.0%, 95% CI, 5.8% to 36.6%), Europe (20.3%, 95% CI, 5.6% to 35.6%), and the UK (21.8%, 95% CI, 6.1% to 37.7%).

The combined worldwide population-attributable risk for the 7 risk factors was 49.4% (95% CI, 25.7% to 68.4%), or 16.8 million attributable cases (95% CI, 8.7 million to 23.2 million) of 33.9 million cases. When researchers adjusted for the association between risk factors, the estimate fell to 28.2% (95% CI, 14.2% to 41.5%), or 9.6 million attributable cases (95% CI, 4.8 million to 14.1 million) of 33.9 million cases.

Combined population-attributable risk estimates were about 30% for the U.S., Europe, and the UK, researchers noted. Reducing the prevalence of each of the 7 risk factors by 10% per decade could reduce Alzheimer’s disease in 2050 by 8.3% worldwide.

Researchers wrote, “Although the analysis herein is necessarily simplistic, and other approaches to reduce disease burden for the tens of millions of people who will develop Alzheimer’s disease or other forms of dementia will be important, public health interventions targeted at vascular risk factors (e.g., physical inactivity, smoking, midlife hypertension, midlife obesity, and diabetes), depression, and low educational attainment will probably achieve the greatest reduction in the prevalence of the modifiable risk factors and will provide other major benefits to society and health-care systems.”

They do make an ultrasound probe that plugs into a USB port!

“They should make an ultrasound probe that plugs into your laptop. It could just hook into a USB port.”

Ultrasound technology has become progressively more accessible to doctors who aren’t radiologists. During my training, some obstetricians imaged the bellies of their pregnant patients to quickly see how the baby was lying in the womb and assess its progress. Other than that, ultrasound resided in the realm of the radiologists, who lived in dark rooms and interpreted blurry pictures for the rest of us.

Since ultrasound is not expensive and has many potential applications, far beyond just seeing fetuses, other specialties have adopted it and doctors in resource poor countries where there are no radiologists have come to rely on it for all sorts of information. Trauma surgeons and emergency physicians can use it to rule in or out life threatening conditions, and internal medicine physicians like me can improve on the accuracy of our physical exams and sometimes avoid the cost of more complex and dangerous imaging procedures. Ultrasound can be used to guide procedures, making them safer. The machines have become smaller and are even pocket sized. It’s all so very exciting.

So why not an app for the iPhone? Why not Google glasses with which one can see ultrasound images of the patient in front of me? Why not a wireless ultrasound transducer?

The possible avenues of progress in very portable ultrasound technology have been slow for various reasons. First, many people are happy with radiologists imaging the body and cardiologists imaging the heart using large and expensive machines. The system works. It doesn’t require the rest of us to learn ultrasound and the pictures are good and the rather large charges benefit hospitals. Bedside, ultrasonographers are looking for inexpensive machines and it is unclear how much the use of these will increase the revenue stream which drives much of what happens in research and development in medicine.

Having wandered through the health care device industry’s displays at many ultrasound conferences and having surfed the Internet I thought I knew what kind of technology was available for doing bedside ultrasound imaging. I had seen an ultrasound transducer that plugged into an iPhone made by a company called Mobisante, and had seen their iPad/transducer combo. The software was buggy and the pictures were not impressive and the whole package did not end up being handy or attractive. I bought the GE Vscan machine which is about the size of my hand, and like my hand, fits in my pocket. The pictures are good and it does most of what I want it to do. So when people asked about just buying a transducer for a laptop and plugging it in I told them that clearly that was a great idea but it didn’t exist.

Except that I was wrong. The company Interson, out of the Bay Area in California, makes transducers for imaging blood vessels, deeper structures such as abdominal organs, and cavities such as the throat and vagina/uterus. I had the opportunity to try their abdominal probe in the last few weeks. It is definitely a clever and versatile device, despite several drawbacks.

The probe is called SeeMore, which will probably not help sell the product. It is about as heavy as a small hardback book and it is a little big to have comfortably in a pocket. It has an inescapable resemblance to a personal vibrator which will also not help sell it. It is actually the same transducer that Mobisante used in their iPhone device. On the very positive side, though, it gives really good pictures of the abdomen, uterus and bladder. Its resolution is good enough that it could be used to rule in or out a pneumothorax, which my Vscan is not quite up to. Its image acquisition is slow so when looking at the heart it is not possible to see the delicate movement of the heart walls or valves, though it is possible to see grossly abnormal cardiac function or pericardial effusion from an abdominal approach. It does not do color Doppler, so it cannot give any indication of blood flow. It has its own software that loads quickly onto a laptop and it could be used with a tablet so long as it has a windows operating system.

The USB attachment can go into a USB to mini-USB converter so the tablet doesn’t even need to have a full size USB port. Once the software is loaded it has calculations that are user friendly and intuitive calipers for measurements plus all of the usual gain adjustments that a person might want. There is a button on the transducer that freezes and unfreezes the image. After images are stored they can be printed or transmitted easily as JPEGs.

If I worked in a bush hospital somewhere and needed my ultrasound just to evaluate unborn babies or critically ill or traumatized patients, this transducer would be just the ticket. If I used a laptop as I went from room to room, as I did at my last job, I can imagine information from this device being integrated seamlessly into my documentation as I examined the patient. The transducer I tried does not visualize superficial structures, like blood vessels or bones or tendons, abscesses or thyroids, but Interson makes a linear transducer that does. Each transducer costs $4000 new, and the software, support and hefty plastic case with tiny tube of ultrasound gel are included. My Vscan cost over $8000 and the cheapest portable ultrasound machine that hospitals in the US buy costs over $40,000 new. (Veterinary ultrasound machines and ones that are used in developing countries can cost much less than this, even in the sub $1,000 range for a used machine.) From where I stand this USB transducer is an affordable alternative for point of care ultrasound, though I do like a machine that gives better pictures of the heart.

What about the Google glasses thing? I think somebody has a patent for that, though it’s not commercially available. What about the wireless transducer? Yes. It exists. It is not Bluetooth, a proprietary short distance wireless connection that uses ultra-high frequency radio waves. It uses a different proprietary ultra wide band wireless connection which can handle more information. The one that I found is called the Freestyle, by Acuson, which is now owned by Siemens. It looks like a TV remote and I think it’s just for superficial structures.

As there is demand, these machines will get lighter, cheaper, more versatile and attractive. The potential is awesome and I’m looking forward to trying out new toys that will allow me more capably to help my patients.

Lessons from the VA--bad performance measures and insufficient primary care

The New York Times has come great reporting on the fundamental problems leading to the “VA crisis.” Doctor Shortage Is Cited in Delays at V.A. Hospitals . The article points out 2 problems.

Let’s first look at the second problem. Administrators cheated to obtain bonuses. Why did that happen? The central office set a performance standard related to how quickly new patients had appointments. What happens when we give performance standards? Unintended consequences! Administrators cannot make physicians see every patient, so they created “work arounds.” Now those administrators are guilty, but I would submit that the performance standard idea should also get blame.

A more important problem comes from the lack of sufficient primary care physicians. This article delineates the problem beautifully. As a former VA physician (part-time for 20 years and only inpatient the last 10 years) I can tell you that the patients who frequent the VA require intense primary care. They often have multiple medical problems and often psychiatric problems. Now the electronic medical record is the best I have seen, but it still takes time to type notes and review the charts.

The VA has great benefits, and often reasonable hours, but the salaries are not great from primary care. And the U.S. has a shortage of primary care physicians, especially internists (who the VA seems to favor). Primary care internists have multiple options. Less internists do primary care than 15 years ago, and partly because many do hospital medicine (higher salary, more predictable hours, and more “days off”).

The VA crisis in primary care will continue until the job improves. The crisis will not stop with the VA. We will soon see the same crisis for Medicare patients and Medicaid patients.

We have to improve the job. We have to decrease the administrative hassles dumped on primary care physicians (actually all physicians). Primary care is the lynchpin of our health care system. Excellent primary care improves outcomes at a lower cost. And our politicians and our insurers have not addressed this issue. We do need to work very hard to fix this problem. The extra moneys put into primary care will save downstream medical costs.

Is the meningitis B vaccine for you?

In February 2013 college student Emily Stillman died of meningitis. She was well-liked, smart, and healthy. And she had received her meningitis vaccine. What went wrong?

Meningitis is an infection of the membranes that line the brain and spinal cord. It can begin with cold-like symptoms but it’s usual symptoms are headache, stiff neck, fever, and sometimes a splotchy rash. Even if treated properly, it often leads to long-term health problems, and is too-often fatal. Because of this, prevention has been an important public health goal.

In the U.S., we’ve done a great job of preventing meningitis. Three of the most important bacteria that cause the disease now have effective vaccines.

Haemophilus influenzae type b (Hib) was a very common cause of childhood diseases, including ear infections. It was a common cause of epiglottitis, a disease that could quickly suffocate a young child. It also causes meningitis. As a medical student, we were instilled with a healthy respect for the disease. We learned the signs of epiglottitis, its appearance on X-ray. But we didn’t see that many cases. Since the introduction of the vaccine in the late 1980s, the incidence of severe disease due to Hib has dropped 99%.

Streptococcus pneumoniae (pneumococcus; sorry, no better nickname available) is a common cause of pneumonia, and like Hib, it can cause ear infections in children. It can also cause meningitis. Before the wide use of the vaccine, about 200 kids died every year of pneumococcus infections, including meningitis. Routine vaccination has led to a 99% decrease in severe pneumococcal disease in children.

The “classic” type of meningitis is caused by Neisseria meningitidis (meningococcus; also no good nickname). This is a bacteria that lives harmlessly in many people, but under the right conditions can migrate into the lining of the brain causing a devastating disease. Our success with vaccination against this disease has been a bit more complex than with the other two. There are many different types of this bacterium, identified by a capital letter. The most common in the U.S. are B, Y, C, W-135. Vaccination against Y, C, and W is has been very effective. In the U.S., type B is rare after infancy, and no vaccine is available. This is the type that killed Emily.

Emily’s case likely occurred outside of an outbreak, as most cases do. There have been, however, 2 outbreaks of type B on college campuses recently, at Princeton and at University of California Santa Barbara. The FDA and CDC allowed the use of a type B vaccine in these outbreaks, but this vaccine hasn’t been approved in the US. It has been used safely for years in Europe and Canada.

Meningitis caused by type B meningococcus is still very rare, and rarer still in outbreaks, but parents of kids heading off to college are worried, if my phone line is any indication. Families here, near the Canadian border, have crossed the bridge to get their kids vaccinated, sometimes in organized groups. I’m often asked if this is a good idea.

The absolute risk of a college-age kid dying from meningitis is very, very small. If it’s your kid though, that’s little comfort. I can’t tell my patients if they should get a vaccine that hasn’t been approved. Unapproved drugs have caused all sorts of problems over the years. But European and Canadian equivalents of the FDA are pretty good. It seems likely that a type B vaccine will be approved for use in the US at some point, but until then, I haven’t discouraged anyone from heading over the border to get one.

A quick trip to the future

I went to the future yesterday and it was boring.

The CONVERGE conference featured leaders in health care and technology who were very excited about the potential for change and innovation in the industry. But most of the concepts they talked about didn't really disrupt my thinking or enter me into a new space (sorry, everyone at the meeting talked that way). Doctors will be more empathetic and practices will be more focused on patient satisfaction. "Wearables" (like the Fitbit) that encourage you to exercise are cool, but no one's figured out how to make people who aren't already healthy use them. Or to the extent that they have, they'll basically be mini versions of the monitors currently used on inpatients. Insurers want to focus on keeping people healthy by collaborating with physicians and paying for value instead of volume.

Are you asleep yet? I was, just about, when Google took the stage, and the future turned from boring to scary. We heard about Glass, of course, and their forthcoming glucose-measuring contact lens, which are both cool, but then the speaker moved on to talking about engaging patients in their health. A lot of the earlier speakers had been wondering about how to do that. From her examples, it seemed that plenty of companies have already figured it out. An acne medication has convinced teenagers to send in a daily photo of their faces, Johnson & Johnson has pregnant women signing up for daily texts, CVS has youtube videos. Notice the theme? The entities that have people listening to their health advice are actually trying to sell them stuff! I asked the speaker whether it was just me or we should maybe be worried about this. Her answer was, basically, yes, it is concerning. (Kind of kicking myself for not thinking to ask whether she had any solutions.)

For the last talk of the day, we got a report from Medtronic's "Hospital of the Future." Or not so much a report, since all the contents are inconveniently proprietary, as a lecture about how it's full of wonderful innovations. Which also seemed a little scary, since the one innovation that the speaker could tell us has made it from the hospital of the future to the real world (somewhere in Europe) is Medtronic-owned cath labs.

So, to summarize, despite the worries of Obamacare opponents, the future of health care (at least according to this conference) is firmly in the hands of corporations.

Making progress with being below the elbows

We have had a recommendation for bare below the elbows (BBE) in the inpatient setting for 5 years at my hospital. No mandate, just a recommendation. And it’s been a fairly soft sell. My perception has been that over time a greater proportion of our health care workers have adopted BBE, but we’ve never formally measured it. Since our hand hygiene observers roam throughout the hospital, we asked them to simultaneously record BBE status while they were collecting their hand hygiene compliance data.

So here’s a first look: 2 weeks of observations (n=1,560). Note that health care workers were not counted repeatedly and our definition of BBE was strict (i.e., a wrist watch or bracelet was defined as noncompliance). The graph below shows the overall compliance and the compliance stratified by job category:

Nurses and nursing students demonstrate high rates of compliance. On the other hand, physicians and medical students are least likely to comply. Nonetheless, nearly 40% compliance in physicians is higher than I would have predicted.

Medical students have 2 problems: they just love the white coat and they are concerned about how they will be perceived by their evaluators if they don’t wear it. Clearly, we have some work to do there. Overall, though, I’m pleased with these results. Two-thirds of patient encounters are by health care workers who are BBE. One caveat is that these data were collected in June. I expect the data will look different in January. We’ll keep watching.

Have you ever had back pain?

Yes, you have. Unless you’re a real statistical outlier, all of us have had (or will get) back pain at some point in our adult lives.

It’s annoying. It hurts. It makes us feel vulnerable. Back pain can mean many things to us:
• a harbinger of serious illness
• a predictor of disability
• a reminder that we’re getting older

There are a couple of key facts you should know about “garden variety” back pain, the kind that 95% of us get.

Of the 95% of us that will get it, 95% of it will be self-limited, as in, it will get better on its own. No need for X-rays. No need for MRIs. And for God’s sake, avoid surgery for low back pain.

There are things you can do to improve back pain, and prevent it from recurring (core strengthening, physical therapy, etc.).

As he’s done with his masterful video about the importance of (at least minimal) exercise, preventive medicine expert Dr. Mike Evans of Toronto (@docmikeevans) has done it again, this time for a scourge common to all of us. Watch the video below when you want to learn what the science really tells us about back pain.

It will change the way you think about your back pain. And hopefully get you working on a ’back resilience plan.

QD: News Every Day--Moderate alcohol use associated with afib risk

Even moderate amounts of wine and liquor may be a risk factor for atrial fibrillation, although beer didn’t have the same association, a study found.

Researchers in Sweden studied nearly 80,000 middle- and late-age adults who completed a questionnaire about food and alcohol consumption in 1997 and were then followed via national registries for 12 years.

Results appeared in the Journal of the American College of Cardiology.

There were more than 7,200 cases of atrial fibrillation among nearly 860,000 person-years of follow-up. The study found an association not only with heavy drinking of more than 3 drinks per day, as well as binge drinking 5 or more drinks at a time, but also with moderate consumption of 1 to 3 drinks per day.

Compared with nondrinkers, the relative risks of atrial fibrillation were 1.01 (95% CI, 0.94 to 1.09) for 1 to 6 drinks/week, 1.07 (95% CI, 0.98 to 1.17) for 7 to 14 drinks/week, 1.14 (95% CI, 1.01 to 1.28) for 15 to 21 drinks/week, and 1.39 (95% CI, 1.22 to 1.58) for >21 drinks/week. Results were similar after excluding binge drinkers.

In a meta-analysis of 7 prospective studies that included more than 12,500 cases of atrial fibrillation, the relative risks were 1.08 (95% CI, 1.06 to 1.10) for 1 drink/day, 1.17 (95% CI, 1.13 to 1.21) for 2 drinks/day, 1.26 (95% CI, 1.19 to 1.33) for 3 drinks/ day, 1.36 (95% CI, 1.27 to 1.46) for 4 drinks/day, and 1.47 (95% CI, 1.34 to 1.61) for 5 drinks/day, compared with nondrinkers. The meta-analysis, which didn’t differentiate between types of alcohol, showed the risk for atrial fibrillation increased 8% with each additional drink per day.

While many studies have shown that light to moderate alcohol consumption reduce ischemic heart disease and stroke, it is important to balance these benefits against the potential risk of developing atrial fibrillation, the researchers noted.

While the association between moderate wine and liquor consumption and increased atrial fibrillation risk was strong, the Swedish study did not find such a relationship with atrial fibrillation and moderate beer consumption or even binge drinking of beer. It is possible that beer is consumed more regularly during the week, whereas wine and liquor is more often consumed during weekends only, which might spread out the adverse effects of alcohol on atrial fibrillation risk.

An accompanying editorial endorsed the study’s findings, but concluded, “Because the AF risk related to consuming low-to-moderate amounts of alcohol (i.e., <2 drinks per day) is small, these data in isolation should not discourage individuals from safely consuming and enjoying such modest amounts of alcohol.”

More sunshine on the Medicare data release

I wrote recently about the release of physician billing information by CMS and noted that news organizations had quickly provided tools to look-up individual physicians. Propublica, an “independent, non-profit newsroom that produces investigative journalism in the public interest” has gone one better. In keeping with their mission to “expose abuses of power and betrayals of the public trust … through the sustained spotlighting of wrongdoing” they recently posted a more powerful online tool for analyzing and viewing the CMS data along with a companion story of what they found by using it.

The tool allows a user to look up any physician who received Medicare payments in 2012 and learn which services he or she billed for, and how his or her billing patterns compare to the patterns for physicians in the same specialty and state. Other features, which are all explained on an instructional video on the site, allow users to see which physicians were most likely to have seen a patient before or after that patient saw the doctor in question, and to look for outliers by rank ordering doctors by services, payments and other parameters. It is easy to use and I almost felt like a voyeur as I clicked through the features. So much data, so easy to access! It was irresistible to look up people I know and peak into their practices, and I can easily imagine savvy patients (not to mention the Medicare Inspector General) doing the same.

Speaking of the IG, my fascination turned to disgust when I read the companion piece about some particularly glaring outliers. I know the data are not perfect. I know this is at best an incomplete picture of how anyone practices, but this was just gross. Coding 95% of your office visits as level 5? Seeing Medicare patients an average of 8 times a year and doing vascular ultrasounds and spirometry on every patient at office visit? Come on. Who can possibly look at that and say it may be justified on the basis of clinical acuity or patient characteristics? This is so beyond anything that is even imaginably justifiable, that it screams “churning” and fraud.

The sad truth is that the doctors practicing this way have been hiding in plain sight, and the these data not only indict them, but also point to regulators asleep at the switch, and a professional community that has failed to police itself.

QD: News Every Day--Another piece to the puzzle of alcohol and heart health

A single gene variation may lead to less alcohol consumption, and may be the reason why there is a perceived health benefit to moderate drinking, a meta-analysis concluded

A variant in the alcohol dehydrogenase 1B gene (ADH1B) leads people to break down alcohol faster, but also causes nausea and embarrassing symptoms such as facial flushing. This leads to drinking less, which is associated with less binging, lower blood pressure, a smaller waist size, and a lower body-mass index. These, in turn, may pass on the benefit of less cardiovascular disease.

The study appeared at BMJ.

Researchers did a meta-analysis of 56 epidemiological studies of nearly 262,000 people of European descent, including more than 20,000 coronary heart disease cases and 10,000 stroke events.

Compared to noncarriers, people with the ADH1B gene drank 17.2% fewer units of alcohol per week (95% CI, 15.6% to 18.9%), had a lower prevalence of binge drinking (odds ratio [OR], 0.78; 95% CI, 0.73 to 0.84), abstained more often (OR, 1.27; 95% CI, 1.21 to 1.34).

Compared to noncarriers, those with the gene had lower systolic blood pressure (−0.88 mm Hg; 95% CI, −1.19 to −0.56), lower interleukin-6 levels (−5.2%; 95% CI, −7.8 to −2.4%), a narrower waist circumference (−0.3 cm; 95% CI, −0.6 to −0.1), and a lower body mass index (−0.17 kg/m2; 95% CI, −0.24 to −0.10).

Carriers also had lower odds of coronary heart disease (OR, 0.90; 95% CI, 0.84 to 0.96). The protective association of the gene remained the same whether the people were light, moderate or heavy drinkers (P=0.83 for heterogeneity). Gene carriers had lower odds of ischemic stroke (OR, 0.83; 95% CI, 0.72 to 0.95), although there was no association across all types of stroke.

The findings suggest that reduction of alcohol consumption, even for light to moderate drinkers, is beneficial for cardiovascular health, researchers noted.

A co-author said in a press release, “For some time, observational studies have suggested that only heavy drinking was detrimental to cardiovascular health, and that light consumption may actually be beneficial. This has led some people to drink moderately based on the belief that it would lower their risk of heart disease. However, what we’re seeing with this new study, which uses an investigative approach similar to a randomized clinical trial, is that reduced consumption of alcohol, even for light-to-moderate drinkers, may lead to improved cardiovascular health.”

An editorial noted that drawing firm conclusions are still difficult, but that more researcher and diverse types of studies are still important to making an eventual conclusion about the role of alcohol and heart health. “Combining evidence from multiple research designs (that is, ‘design diversity’) will prove enlightening in the long run, even if conclusions are puzzlingly inconsistent and difficult to interpret in the short run.”

The anti-medication bias

[The patient interactions in this post are amalgams of hundreds of patient encounters over my career. They are not accurate depictions of any encounter with any single patient.]

“I don’t like taking medicines.”

All physicians hear some form of this opinion very frequently. Even more frequently, patients don’t state this view outright but rely on it to completely subvert their doctor’s plans.

When I was new to practice such an utterance would shock and confuse me.

“I don’t want to take any medicines,” a patient would declare.

“That’s fine,” I would reassure my interlocutor. “It’s a free country. No one is going to force you to take medicines. But you should know that I’m a primary care doctor. I don’t do surgeries or procedures. I diagnose and treat medical problems, usually with medications. I’m not saying you have to change your opinion. I’m just saying you might be in the wrong place. You’re like the vegan bursting into the butcher shop to declare that you don’t want to buy meat.”

I’ve heard some version of this aversion to medications hundreds of times. Over the years I’ve also realized that it is usually adopted by patients without any serious reflection.

“I’d like to be on the fewest medications as possible,” a patient with diabetes, heart disease, high cholesterol, and high blood pressure would announce.

“Well, the fewest medications you can take is 0. Should we just stop them all?”

Lots of patients adopt this anti-medication preference in the absence of any evidence or serious thought. A strong preference without analysis or evidence is simply a bias. (When I have a strong preference in the absence of evidence, it’s a philosophy; when other people have it, it’s a bias.)

Now, some biases are harmless. I like Folgers instant coffee (black), and you like vanilla Frappuccino. I bicycle; you jog. That’s all great. But if a bias threatens to worsen your health, it deserves a little attention. Some thinking might be useful to either confirm it as a belief you want to live by, or discard it to the cognitive ash heap.

The problem with the anti-medication bias is that most doctors are too busy to argue with you. Let’s say your cholesterol is extremely high. Your doctor might recommend attempts at exercise and weight loss for a few months. After that if your cholesterol is unimproved she may recommend a cholesterol-lowering medication. She may or may not have time to mention that this medication has been proven to prevent strokes and heart attacks in patients with high cholesterol. She might or might not mention the rare and usually tolerable side effects you might expect. But if all she hears from you is “I’m already taking too many medicines,” she may do the expedient thing, which is to document your refusal to take cholesterol medicine and leave it at that. If you’re lucky, she’ll readdress this again in more detail in a future visit. If you’re unlucky the future visit will be when she sees you in the emergency department during a heart attack.

Because I have more time to spend with each patient than most doctors, I have a lot of experience in trying to understand and overcome this anti-medication bias. I certainly don’t advocate compensating with the opposite bias by taking as many medications as possible. (A small number of patients do seem to believe that there is a pill for everything that ails them. That’s a subject for a different post.) My suggestion instead is that each medication be judged on the basis of its own benefits and harms. You don’t want to minimize the medicines that you take; you want to benefit from all the medicines whose benefits to you exceed the harms.

Now, don’t get me wrong. There are certainly good reasons not take a medication. You might develop a side-effect. Discuss that with your doctor. Some side-effects diminish with time. Some are annoying but not dangerous. But obviously some are intolerable and might be a good reason to stop taking a medication. So by all means balance the risks, the expense, and the side effects of medications against their benefits, but don’t make a decision before even doing the calculation.

Of course balancing these issues takes time and thought. It requires that the patient be willing to ask important questions (“What side effects should I expect?”) and express any apprehensions. It requires that the doctor answer the questions and make sure the patient understands why the medication is being recommended. That is more difficult and less efficient than writing a prescription and bolting to the next patient.

So please help me eradicate the anti-medication bias. Your health might improve, and you’ll save your doctor a headache or 2. Which reminds me, I need some ibuprofen.
