Objective: Pneumonia that develops 48 hours after intubation has been defined as ventilator-associated pneumonia (VAP) in patients hospitalized in the intensive care unit (ICU). Late-onset VAP (LO-VAP) is described as pneumonia that occurs within or after the 5th day of mechanical ventilation. We aimed to determine the factors that affect the mortality and survival in patients with LO-VAP.

Materials and Methods: We retrospectively reviewed the hospital records of adult patients (>18 years) who developed LO-VAP in the training and research hospital between January 2014 and June 2018. We compared the demographic findings and laboratory characteristics of the survivors and deaths on the 28-day mortality.

Results: The mean age of 231 (90 female and 141 male) patients with LO-VAP was 73.43±14.06 years. As a result of multivariate logistic regression analysis, we determined that advanced age (p=0.023; 95% confidence interval [CI]: 1.003–1.047) and unconsciousness (p=0.001; 95% CI: 1.674–6.547) were the independent factors affecting mortality. However, parenteral nutrition (PN) (p=0.027; 95% CI: 0.263–0.923) and tracheostomy (p=0.001; 95% CI: 0.112–0.545) were the independent factors supporting survival. We found that acute physiology and chronic health evaluation II score, presence of bacteremia, and enteral nutrition did not have a significant effect on mortality.

Conclusion: Use of tracheostomy and PN in patients with LO-VAP has a positive effect on survival. Our study also points out that mortality can be high in patients with advanced age and unconsciousness.
