Post-tonsillectomy hemorrhage: cost-benefit analysis of prolonged hospitalization.

Prolonged hospitalization after tonsillectomy up to three nights was implemented to decrease mortality due to post-tonsillectomy hemorrhage. To assess if extension of postoperative inpatient observation time from one to three nights results in potential benefits following tonsillectomy. Patients who stayed only one night post-tonsillectomy between 1994 and 2006 (Group A) were compared to 1570 patients who stayed three nights postoperatively between 2008 and 2016 (Group B).
