Brief Summary

The aim of the study is to compare cases of ventilator-associated pneumonia with matched controls of mechanically ventilated patients to identify any relevant independent risk factors for ventilator-associated pneumonia. All adult (≥ 18 years) mechanically ventilated patients > 48 hours who are diagnosed with ventilator-associated pneumonia are considered as cases. The control group are mechanically ventilated patients and matching with cases regarding their age, gender, and duration of mechanical ventilation.

Detailed Description

Ventilator-associated pneumonia is associated with long hospital stays and significant costs. It also prolongs the length of mechanical ventilation. Incidences of ventilator associated pneumonia are highly influenced by the characteristics of the patient population studied and the criteria and techniques applied for diagnosis. The reported incidence is ranged between 10-20% of mechanically ventilated patients. This incidence in developed countries differs significantly from that in developing ones due to many reasons. Several risk factors are identified. The risk factors can be host, device, or personnel related. The most reproducible risk factor is the duration of mechanical ventilation.

The most well recognized modifiable risk factors are mainly intervention related causes. Despite widespread ventilator-associated pneumonia prevention efforts, there was a 35% increase in the ventilator associated events between 2019 and 2020. Since critically ill patients are dynamic patients who are in need to multiple interventions and techniques, revisiting the risk factors of VAP is essential.

Despite widespread prevention efforts, VAP prevention bundles, surveillance systems and updating definitions by CDC, there was a 35% increase in the ventilator associated events between 2019 and 2020 according to CDC healthcare associated infections progress report in 2020. Since critically ill patients are dynamic patients who are in need to multiple interventions and techniques, revisiting the modifiable risk factors of VAP is essential.
