From 2006 to 2012, the incidence of ventilator-associated pneumonia (VAP) reported to the Centers for Disease Control and Prevention National Healthcare Safety Network (NHSN) decreased.1,2 In medical and surgical intensive care units, between 2006 and 2012, the reported incidence of VAP per 1000 ventilator-days decreased from 3.1 to 0.9 (71% decline) and 5.2 to 2.0 (62% decline), respectively. Whether the decrease was attributable to better care or stricter application of subjective surveillance criteria is unclear.3 The Medicare Patient Safety Monitoring System (MPSMS)4 has independently measured VAP rates since 2005, using a stable definition of VAP. Trends in MPSMS VAP rates from 2005 through 2013 were analyzed.
