Table 2 Main clinical outcomes

From: In-hospital mortality of patients requiring unplanned postoperative ventilatory support: a multicenter observational study

Outcome All patients (N = 698) Extubated in PACU (N = 429) Not extubated in PACU (N = 269)  
Primary outcome     aOR (95% CI)
 In-hospital mortality 135 (19%) 38 (9%) 97 (36%) 5.8 (3.8–8.8)
Secondary outcomes     aOR (97.5% CI)
 Unplanned ICU admission 317 (45%) 97 (23%) 220 (82%) 14.8 (8.9–24.6)
 Postoperative respiratory infection 97 (14%) 39 (9%) 58 (22%) 2.7 (1.7–4.5)
Composite outcome     aOR (95% CI)
 Mortality, ICU admission, or respiratory infection   131 (30.5%) 250 (92.9%) 29.9 (18.0–49.8)
  1. Comparison of the primary, secondary, and exploratory outcomes between patients extubated during PACU stay versus remaining intubated beyond PACU discharge. Results reported as adjusted odds ratios and 95% (for the primary and exploratory outcomes) or 97.5% (Bonferroni, for the 2 secondary outcomes) confidence intervals.
  2. CI confidence interval, aOR adjusted odds ratio, ICU intensive care unit, PACU postanesthesia care unit
