Table 1 Outcomes and antibiotics in the Canadian Critical Care Trials Group study [1]

From: Is bronchoalveolar lavage with quantitative cultures a useful tool for diagnosing ventilator-associated pneumonia?

  Endotracheal aspiration (n = 374) Bronchoalveolar lavage (n = 365)
Outcomes
   Mortality at day 28 (%) 18.4 18.9
   Duration of mechanical ventilation (days) 8.8 (7.0–10.7) 8.9 (7.4–10.7)
   Duration of intensive care unit stay (days) 12.2 (10.9–14.2) 12.3 (10.9–13.8)
   Final diagnosis of ventilator-associated pneumonia (%) 82.9 86.3
Antibiotics
   Adequacy of empirical treatment among patients with positive cultures (%) 89.5 89.0
   Targeted therapy by day 6 (%) 74.6 74.2
   Number of days alive without antibiotics 10.4 ± 7.5 10.6 ± 7.9
