QD: News Every Day--Hospitals improve their rates of health care acquired infections

Health care acquired infections fell in recent years and remained lower, according to a report by the Centers for Disease Control and Prevention.

Hospitals reported 32% fewer central line-associated bloodstream infections, 6% fewer catheter-associated urinary tract infections, and 8% fewer surgical site infections than predicted based on the case-mix of patients and locations that were monitored.

Moreover, the central-line infection success improved between reporting periods, as the standardized infection ratios (SIR) during 2010 was significantly decreased (SIR 0.684, 32% reduction in central-line infections) compared to 2009 (SIR 0.854, 15% reduction in central-line infections). This suggests that the facilities not only sustained the prevention success of 2009, but improved even more in 2010.

Such improvement was more modest for surgical site infections. The overall SIR decreased from 0.981 to 0.916 when including all reporting facilities, but the decrease lost statistical significance when limiting the comparison to only facilities reporting in both years, according to the report.

For surgical site infections, improved prevention success over the two years was greatest for coronary artery bypass grafts (in 2010, 18% surgical site infections prevented), while stable reductions in surgical site infections were evident for two of the nine other operative procedures evaluated (knee arthroplasty, 11% reduction; colon surgery, 9% reduction).
