Reducing VAP Rates to Near Zero Requires Multiple Interventions and Performance Measures
Ventilator-associated pneumonia (VAP) is a common infection in the intensive care unit (ICU) and associated with a high mortality. Caserta, et al. conducted a quasi-experimental study in a medical-surgical ICU; multiple interventions to optimize VAP prevention were performed from October 2008 to December 2010. All of these processes, including the Institute for Healthcare Improvement (IHI)'s ventilator bundle plus oral decontamination with chlorhexidine and continuous aspiration of subglottic secretions (CASS), were adopted for patients undergoing mechanical ventilation.
The researchers evaluated a total of 21,984 patient-days, and a total of 6,052 ventilator-days (ventilator utilization rate of 0.27) and found VAP rates of 1.3 and 2.0 per 1,000 ventilator days respectively in 2009 and 2010, achieving zero incidence of VAP several times during 12 months, whenever VAP bundle compliance was over 90 percent.
The researchers say these results suggest that it is possible to reduce VAP rates to near zero and sustain these rates, but it requires a complex process involving multiple performance measures and interventions that must be permanently monitored. Their research was published in BMC Infectious Diseases.

Swift Isolation Protocol Shields Chicago Children’s Hospital During 2024 Measles Surge
June 17th 2025When Chicago logged its first measles cases linked to crowded migrant shelters last spring, one pediatric hospital moved in hours—not days—to prevent the virus from crossing its threshold. Their playbook offers a ready template for the next communicable-disease crisis.
Back to Basics: Hospital Restores Catheter-Associated UTI Rates to Prepandemic Baseline
June 16th 2025A 758-bed quaternary medical center slashed catheter-associated urinary tract infections (CAUTIs) by 45% over 2 years, proving that disciplined adherence to fundamental prevention steps, not expensive add-ons, can reverse the pandemic-era spike in device-related harm.
