Recent Trends in the Management of Ventilator-Associated Pneumonia

Ventilator-associated pneumonia (VAP) occurs frequently in mechanically ventilated patients and has a high mortality rate. To date, there is no consensus for the diagnosis of VAP. Effective reduction in VAP-inducedmortality requires amultifaceted approach to include assessment of individual risks for VAP, implementation of effective ventilator handling procedures, routine use of VAP prevention strategies, appropriate use and interpretation of invasive and noninvasive diagnostic tests, and early broad spectrum antibiotic coverage with narrowing of coverage and cessation of therapy based on clinical improvement. Pharmacokinetic and pharmacodynamic principlesmust be used in designingempiric antibiotic regimens. Because an inappropriate empiric regimen in VAP has been associated with increasedmortality, it is imperative to maintain intensive care unit–specific epidemiologic data.
