Clinical Pulmonary Infection Score (CPIS) for Ventilator-Associated Pneumonia (VAP)
Assists in diagnosing ventilator-associated pneumonia by predicting benefit of pulmonary cultures.
Many reviews of the CPIS feel it should not be relied on; we include it because of its popularity but caution users to review the data on its utility first.
