Ventilator-associated pneumonia remains a major challenge in the intensive care unit. The role for invasive diagnostic methods (e.g., bronchoscopy) remains unclear. We hypothesized that invasive testing would alter antibiotic management in patients with ventilator-associated pneumonia but would not necessarily alter mortality.Meta-analysis of randomized, controlled trials of invasive diagnostic strategies in suspected ventilator-associated pneumonia and a separate pooled analysis of prospective, observational studies of the effect of invasive cultures on antibiotic utilization in ventilator-associated pneumonia.NA.Subjects enrolled in the various clinical trials identified.None.We identified four randomized, controlled trials that included 628 patients. The overall quality of these studies was moderate (median Jadad score of 5) and there was both clinical and statistical heterogeneity among these trials. Ventilator-associated pneumonia was confirmed bronchoscopically in 44-69
