The role of surgery on ambulatory patients in one teaching hospital.

The development of a program of one-day surgery for ambulatory patients in one hospital was stimulated by overloaded operating room facilities and a long waiting list of patients for hospital admission. This concept has received enthusiastic reception by the surgical staff and the number of operations has increased to over 7,500 per year. All of the surgical specialty services use the surgical day care unit, although the number of cases suitable for ambulatory surgical treatment varies greatly on the various services. There have been no deaths and about 1% of patients have been admitted to the hospital from the surgical day care unit for a variety of reasons that are summarized.
