    Abstract:
    BACKGROUND: Day surgery constitutes an important part of modern otolaryngology practice. However, high rates of unplanned admissions remain an issue. OBJECTIVE: To determine the incidence, reasons, and predictive factors for unanticipated admission after ambulatory otolaryngologic surgery. METHODS: A retrospective review of all cases of unplanned admission following otolaryngology day surgery at a tertiary care centre over a 4-year period from 2000 to 2004. Data relating to patient demographics, physical status, surgical procedure, perioperative complications, and reasons for hospital admission were recorded. A case-control analysis of these parameters with nonadmitted day surgery patients was used for comparison. RESULTS: During the above period, 1106 patients underwent otolaryngologic day surgery, of whom 74 (6.7%) required admission. Fifty-seven percent of the patients were male, and the average age was 48.9 years. The three most common procedures with unplanned admission were open neck biopsy (27%), functional endoscopic sinus surgery (20.3%), and panendoscopy (16.2%). The reasons for admission could be divided into airway monitoring (37.7%), postoperative bleeding (28.6%), the need for supportive or pain management (19.5%), anesthetic complication (5.2%), cardiovascular complication (3.9%), clerical error (3.9%), and suspicion of a cerebrospinal fluid leak (1.3%). Risk factors for admission were determined to be an American Society of Anesthesiologists' class of 3 or greater, open neck surgical procedures, and a length of surgery of 60 minutes or greater. Minor factors included the use of general anesthesia, male gender, advanced age, and living far from a hospital. CONCLUSIONS: This study suggests strategies to reduce the rate of unplanned admission by means of careful preoperative assessment and planning, patient selection, careful scheduling of higher-risk patients, and appropriate postoperative observation and management.
