Background: Nonventilator hospital-acquired pneumonia (NV-HAP) is among the most common hospital-acquired infections. The purpose of our study was to quantify the incidence and influence of NV-HAP in the United States using a national dataset.

Methods: The 2012 US National Inpatient Sample dataset was used to compare an NV-HAP group to 4 additional group cohorts: pneumonia on admission, general hospital admissions, matched on mortality and disease severity, and ventilator-associated pneumonia (VAP). The main outcome was NV-HAP incidence. The secondary outcome was to compare hospital length of stay, total hospital charges, and mortality between the NV-HAP group and the 4 additional group cohorts.

Results: The overall incidence of NV-HAP was 1.6%, which represents a rate of 3.63 per 1,000 patient-days. NV-HAP was associated with increased total hospital charges, a longer hospital length of stay, and greater likelihood of death in comparison to all groups except patients with VAP.

Conclusion: NV-HAP is an underappreciated and serious patient safety issue, resulting in significant increases in cost, length of stay, and mortality. Efforts toward prevention of NV-HAP should be raised to the same level of concern as VAP prevention.

Keywords: Hospital cost; Mortality; VAP.
