Nosocomial Pneumonia in Mechanically Ventilated Patients | Risk Factors

Purpose: To identify risk factors for development of nosocomial pneumonia in ICU patients receiving mechanical ventilation.

Description

Drakulovic et al identified risk factors for nosocomial pneumonia in patients receiving mechanical ventilation in the Intensive Care Unit. They found that the supine position favors gastroesophageal reflux and aspiration, especially in patients receiving enteral feedings. The study was done at the University of Barcelona in Spain.

= SUM(points for the 4 risk factors)

 

Interpretation:

• minimum number of risk factors: 0

• maximum number of risk factors: 4

• The more risk factors present, the greater the risk of nosocomial pneumonia.
