US hospitals have made progress in preventing healthcare associated infections, but such infections remain common and are often caused by difficult to treat, antibiotic resistant organisms, a study by the Centers for Disease Control and Prevention (CDC) has found.
Researchers compared the number of infections reported in 2014 with a predicted number of infections based on historical baselines established over several years for central line associated bloodstream infections, surgical site infections, catheter associated urinary tract infections, and Clostridium difficile infections. The study was reported in the CDC’s Morbidity and Mortality Weekly Report and led by Lindsey M Weiner, of the Division of Healthcare Quality Promotion at the CDC’s National Center for Emerging and Zoonotic Infectious Diseases.

About 4000 acute care hospitals, 501 long term acute care hospitals, and 1135 inpatient rehabilitation facilities in all 50 states, the District of Columbia, and Puerto Rico reported infections to the CDC’s National Healthcare Safety Network.
The researchers found that short term acute care hospitals had seen a 50% decline in central line associated bloodstream infections from 2008 to 2014 and a 17% decline in surgical site infections over the same period, but no change was found in the incidence of catheter associated urinary tract infections from a 2009 baseline.
In long term acute care hospitals, central line associated bloodstream infections fell by 9%, while catheter associated urinary tract infections fell by 11%. Inpatient rehabilitation facilities saw a 14% reduction in catheter associated urinary tract infections from baseline.
Hospital onset C difficile infections actually increased by 4% during 2013-14, meaning that these infections decreased by only 8% from the baseline established in 2011.
