Achieving and Sustaining Ventilator-Associated Pneumonia–Free Time among Intensive Care Units (ICUs): Evidence from the Keystone ICU Quality Improvement Collaborative

Our retrospective analysis of the Michigan Keystone intensive care unit (ICU) collaborative demonstrated that adult ICUs could achieve and sustain a zero rate of ventilator-associated pneumonia (VAP) for a considerable number of ventilator and calendar months. Moreover, the results highlight the importance of adjustment for ventilator-days before comparing VAP-free time among ICUs.
