Summary

This study developed a scoring system to identify intensive care unit (ICU) patients at high risk for developing nosocomial pneumonia (NP). The system helps stratify patients, enabling targeted prevention strategies for hospital-acquired infections.

Area of Science:

  • Critical Care Medicine
  • Infectious Diseases
  • Epidemiology

Background:

  • Nosocomial pneumonia (NP) is a significant concern in intensive care units (ICUs).
  • Effective risk stratification is crucial for preventing hospital-acquired infections in critically ill patients.

Purpose of the Study:

  • To develop a scoring system for stratifying ICU patients by risk of developing nosocomial pneumonia (NP).
  • To determine the probability of NP development in ICU patients based on available variables.

Main Methods:

  • A 2-year prospective cohort study involving 756 patients admitted to a medical and surgical ICU.
  • Multivariate analysis was used to identify independent risk factors for NP.
  • A scoring system was developed based on identified risk factors to create a predictive risk index.

Main Results:

  • 17.1% of patients developed NP, with 14% occurring within the first two weeks.
  • Independent risk factors identified include: no infection on admission, thorax drainage, antacid administration, PO2 > 110 mmHg, male gender, urgent surgery, and neurological diseases.
  • The probability of developing NP ranged from 11.0% in the lowest risk group to 42.3% in the highest risk group.

Conclusions:

  • ICU patients can be effectively stratified into high- and low-risk groups for NP.
  • Key risk factors for NP include: no infection on admission, thorax drainage, antacid administration, and PO2 > 110 mmHg.
