Evaluation of ventilator associated events in critically ill patients with invasive mechanical ventilation : A prospective cohort study at a resource limited setting in Northern India
Copyright © 2021 Elsevier Inc. All rights reserved..
PURPOSE: The primary aim of this study was to identify the modifiable risk factors for acquiring ventilator associated events (VAE). Secondary aims were to investigate the intensive care unit (ICU) course and impact of VAE on patient outcome.
METHODS: This prospective, observational single center cohort study included 247 patients on mechanical ventilation for 4 calendar days at a 20-bed ICU between January 2018-June 2019.
RESULTS: VAE occurred in 59 episodes (rate 11.3 per 1000 ventilator-days). The Ventilator Utilization Ratio (VUR) was 0.57. The median time to onset of VAE was 6 days. Sepsis was the most common reason for initiating patients on invasive mechanical ventilation (IMV). Cumulative fluid balance ≥2 l (Odds Ratio 30.92; 95% CI 9.82-97.37) and greater number of days with vasopressor support (Odds Ratio 1.92; 95% CI 1.57-2.36) within 7 days of initiating IMV were significant risk factors for acquiring VAE (p < 0.001). VAE cases were ventilated for significantly more days (20 vs 14 days, p = 0.001, had longer days of ICU stay (29 vs 18 days; p = 0.002) and higher hospital mortality (p = 0.02). Klebsiella pneumoniae was the most common isolate (N = 28) and 32.1% were colistin resistant.
CONCLUSIONS: Prospective intervention studies are needed to determine if targeting these risk factors can lower VAE rates in our setting.
