Unplanned Admission After Day Surgery: A Historical Cohort Study in Patients with Obstructive Sleep Apnea

The rate of unplanned admission was 7.0% (95% confidence interval [CI] 5.1 to 8.9) in OSA patients compared with 5.6% (95% CI 4.1 to 7.1) in patients without OSA (odds ratio 1.26; 95% CI 0.83 to 1.91; P = 0.246). Median [interquartile range; IQR] hospital length of stay was 7 hr [IQR 5, 8] with OSA and 6 hr [IQR 5, 8] without OSA (P = 0.058). Severity of OSA was not associated with unplanned admission. They did not identify a clinically important increased rate of unplanned admission associated with a prior diagnosis of OSA.
