Using Evidence-Based Practice to Prevent Ventilator-Associated Pneumonia

Strategies are needed to help prevent ventilator-associated pneumonia.

To develop a ventilator bundle and care practices for nurses in critical care units to reduce the rate of ventilator-associated pneumonia.

The ventilator bundle developed by the Institute for Healthcare Improvement was expanded to include protocols for mouth care and hand washing, head-of-bed alarms, subglottic suctioning, and use of an electronic compliance feedback tool. Compliance audits were used to provide immediate electronic feedback.

Adherence to practices included in the bundle increased. Compliance rates were greater than 98% for prophylaxis for peptic ulcer disease and deep-vein thrombosis, interruption of sedation, and elevation of the head of the bed. The compliance rate for the oral care protocol increased from 76% to 96.8%. Readiness for extubation reached at least 92.4%. Rates of ventilator-associated pneumonia decreased from 9.47 to 1.9 cases per 1000 ventilator days. The decrease in rates produced an estimated savings of approximately $1.5 million.

Strict adherence to bundled practices for preventing ventilator-associated pneumonia, enhanced accountability for initiating protocols, use of a feedback system, and interdisciplinary collaboration improved patients’ outcomes and produced marked savings in costs.
