There is continued encouragement to increase the use of day surgery. Recent publications have suggested that day-case tonsillectomy is a safe procedure due to the low primary haemorrhage rates (0.14-3.5%). One of the suggested benefits of day surgery is that patients want it. They prefer to recover at home after an operation. With tonsillectomy, personal experience suggested that this was not the case. A review of 117 patients having tonsillectomy was undertaken. All patients stayed in for at least one post-operative night. No patients or parents thought that the post-operative stay was too long (80% 'just right', 20% 'too short') and only 7% would have been happy to go home on the day of operation. 'Safety' does not automatically make an operation suitable for day-case surgery. Pain, nausea, vomiting, drowsiness and anxiety about the operation and post-operative course were all reasons given for not wanting to go home on the day of surgery. The justification for the increased use of day surgery is that it increases efficiency by reducing costs per case while maintaining the quality of care. One aspect of quality of care is patient acceptability and before day-case tonsillectomy is acceptable to patients the factors responsible for the post-operative morbidity need to be addressed.
