C. difficile and hospital process measures
One of the more difficult things to cover is a study that you've already written about in an accompanying editorial. It's quite hard to come up with anything “new” to write that you haven't already written. Such is the case with a very nice study examining hospital process measures and Clostridium. difficile infections (CDI) just published in BMJ Quality and Safety by Nick Daneman and colleagues from Sunnybrook Health Sciences Centre in Toronto.
Using results of a mandatory CDI prevention practices survey they compared facility-level processes measures and patient level (via ICD-10 codes) CDI rates in 159 Ontario hospitals. Specifically, they looked at implementation of 6 hospital-level measures: (1) isolation at diarrhea onset, (2) audit of antibiotic use, (3) audit of environmental cleaning, (4) vancomycin as first line therapy and (5) on-site diagnostic testing and (6) reporting of rates to senior leadership. Somewhat surprisingly, none of the process measures were associated with lower risk of CDI.
In the editorial, Nasia Safdar and I wrote:
“First, the authors identified low self-reported implementation of most CDI prevention practices, with only 27% of facilities reporting isolation of all patients at onset of diarrhoea, and 16% reporting auditing of antibiotic stewardship practices. Low adherence rates for these two practices in particular are concerning because prompt institution of contact precautions is necessary to reduce nosocomial transmission of C. difficile. And antimicrobial stewardship is at least as important as infection prevention practices, if not more so, for reducing CDI.”
“This study also highlights the importance of implementation science research to tackle the vexing yet pervasive problem of low and variable adherence to evidence-based interventions for reducing HAI, including CDI. The scope of this study did not extend to exploring barriers to implementation or an in-depth assessment of the self-reported practices that may help inform implementation strategies to increase uptake of proven practices.”
and of course my favorite part:
“Last, increasing the evidence base for preventing CDI by undertaking pragmatic randomised controlled trials of novel interventions incorporating efficacy and effectiveness is essential to successfully bridge the quality chasm that currently exists in CDI prevention.”

The affect heuristic and conflicts of interest
Understanding the affect heuristic leads one to expand their understanding of the term “conflict of interest”. My simple explanation of the affect heuristic follows:
If you like something, you overestimate the benefits and underestimate the risk. The contrary holds also. If you dislike something, you underestimate the benefits and overestimate the risks.
This concept helps us understand that we should consider multiple conflicts of interest. Clearly the pharmaceutical and device industries have taken advantage of this concept. They hire very likable representatives. These representatives treat physicians very well. Physicians, nurses and office staff like the representatives. Thus, the companies are well considered. When considering a drug that they are selling or a device that they make, the recipients of the kindness attribute benefits and minimize risks for the drug or the device.
The same phenomenon occurs when the business funds research. The recipients of the research funds will have their values changed.
These values change subconsciously. We need not say that the conflict is explicit.
But there are other major conflicts. Our expertise is a conflict. For example, my thoughts about pharyngitis induce the affect heuristic. Being a diabetologist induces the heuristic. Diabetologists overestimate the value of tight control, and suppress the estimates of risks. Interventional cardiologists overestimate the benefits of stenting and underestimate the relative benefits of coronary arty bypass grafting.
Insurance company executives underestimate the benefits of expensive treatments.
The only logical way of avoiding conflicts of interest is to balance our committees and thereby balance the conflicts.
Most guideline writers and performance measurement developers would deny that they have a conflict. But we all have some conflict. We should acknowledge our conflicts and make them explicit.
We cannot avoid conflicts, thus we should consider the competing conflicts.
db is the nickname for Robert M. Centor, MD, FACP. db stands both for Dr. Bob and da boss. He is an academic general internist at the University of Alabama School of Medicine, and is the Regional Associate Dean for the Huntsville Regional Medical Campus of UASOM. He still makes inpatient rounds over 100 days each year. This post originally appeared at his blog, db's Medical Rants.
I have written previously about some “aha moments“ that I have had as a clinician, when something that I knew was coming seemed to arrive with a thud in my own practice. I had another one of those moments a couple of weeks ago.
I was finishing up with a new patient, and had explained to him and his wife my assessment and recommendations, and had answered a bunch of questions they had. I was frankly feeling pretty good about how the encounter had gone and as he was walking out of the exam room he said (more or less): “Thanks doc; I'm glad I came to see you, and I am going to give you a really nice review on Yelp.” He was not kidding.
I didn't know quite what to say immediately, but I ended up thanking him (somewhat awkwardly, I suspect) and then recovered enough to tell him that while I would of course appreciate a nice review on Yelp, I wanted him to know that he might be getting a patient satisfaction survey in the mail, and I would really appreciate it if he filled it out and sent it back in. Encounter over. New world order in place.
As someone who has written a lot about measuring the patient experience it came as no surprise that there were plenty of opportunities out there for patients to rate my performance. Indeed, the presence of all of these “rating sites” is one of the reasons why I support the public reporting of validated survey data from real patients. It is a way for us to displace “bad” data (like a review that could have been entered by someone who didn't even see me—gee, thanks Mom!) with “good” data, and by so doing, reinforce the trust our patients place in us.
Look, I don't love the idea that every patient encounter can lead to an internet review, but that is the world in which we live, and I think it is way better to embrace it than pretend it will go away.

Paying smokers to quit
Smoking is a major cause of heart attacks, strokes, emphysema, and lung cancer. Smoking rates have steadily declined in the U.S. in the last 50 years, but about a fifth of U.S. adults still smoke. Helping them quit would make a major contribution to their health.
A study in the current issue of the New England Journal of Medicine (NEJM) studied the effectiveness of different incentive programs on smoking cessation. Over 2,500 smokers were randomized into 3 groups. One group received “usual care”, meaning encouragement to quit smoking and information about quitting programs and nicotine replacement products. Another group was invited to join a “reward program” in which each subject who successfully quit smoking for 6 months received an $800 reward. The third group was invited to join a “deposit program” in which each subject had to pay $150 which would be forfeited if the subject kept smoking. If the subject quit smoking for 6 months, however, she would receive her deposit back and an additional $650.
Six percent of the usual care group had successfully quit smoking for 6 months. Ninety percent of those invited to join the reward program enrolled, and 16% of them successfully quit smoking for 6 months, much more than the usual care group. Of the subjects invited to join the deposit program only 14% accepted. But of those who accepted, over half successfully quit smoking for 6 months (or 7.6% of those invited).
So overall, the deposit group did worse than the reward group, because so few people accepted enrollment into the deposit group. Of those who enrolled in both groups, the deposit group did much better. The findings of the study are well summarized in this short video.
This study sits at an intersection between health research and a relatively new field called behavioral economics. Behavioral economics studies the consistent ways that people make irrational decisions. One finding that has been substantiated by many studies in behavioral economics is the phenomenon of loss aversion—people avoid losses more then they seek gains. For example, most of us will work harder or sacrifice more to avoid a $50 loss than to make $50.
A related NEJM editorial makes the point that this study demonstrated loss aversion in 2 ways. One was that the subjects who agreed to the deposit program were much more likely to quit smoking than those who agreed to the reward program. That means that people were more willing to quit smoking to recoup their own money than to make additional money. The second demonstration of loss aversion is that so few people agreed to enroll in the deposit program.
I'm sure there are practical lessons here both for policy makers and for friends and colleagues of smokers. If I had a close friend who smoked I would suggest that he write a check to a cause or a candidate or a group that he absolutely loathes. He hands the check to me. I promise that if he quits smoking and doesn't restart in a year I tear up the check, but if he doesn't then I mail the check. I suspect if the check amount was painful enough, the success rate would be very high.
