Unanticipated hospital admission after ambulatory surgery

The unplanned admission rate is considered to be an important measure of the quality of ambulatory surgical units. The objective of our study was to evaluate the unanticipated hospital admission rate from the Surgical Day Care (SDC) unit of our university affiliated teaching hospital and to analyze the reasons for admission. A review of all unanticipated admissions over a one-year period was done. The admission rate was calculated and the reasons for admission were analysed. The overall admission rate was 4.93%. Most of the admissions were ordered by the surgeons (97%). The main reasons for admission were patient observation indicated for various reasons (72%) and patient request (18%). Eighty percent of the admitted patients had received general anaesthesia. Admissions were also related to the male gender (69%), age over 65 years (27%) and surgeries ending in the afternoon (69%). On analyzing the reasons for admission, a large number of admissions were found to be due to preventable causes. We conclude that proper selection of patients, careful scheduling of lists and education of patients and clinical professionals can help to avoid many unanticipated admissions after day care surgical procedures.
