This review examines the effect of unanticipated admission, return hospital visits and readmission on the economics of ambulatory surgery. The overall rate of unanticipated admission was approximately 1% and the overall rate of readmission to hospital was approximately 1%. Ambulatory surgery allows total cost savings of 20-50% when compared with inpatient surgery. If 98% of ambulatory surgery p...
