A Prospective Evaluation of Postoperative Readmissions After Outpatient Hand and Upper Extremity Surgery.

Abstract

IntroductionHand and upper extremity surgeries are largely performed in free-standing ambulatory surgery centers (ASCs). Rates of unexpected hospitalizations or visits to the urgent care or emergency departments in the month following hand and upper extremity surgery have been widely varied in the literature. We prospectively followed patients after hand and upper extremity outpatient surgery to determine the rate of unplanned health care utilization with the hypothesis that hospital admissions, emergency room visits, and urgent care center visits would be higher than the rates currently reported by retrospective studies.MethodsAll patients undergoing outpatient hand and upper extremity surgery by five hand surgeons were prospectively followed to monitor for hospital readmissions, emergency room visits, and urgent care presentations. The patients’ postoperative course was evaluated for direct transfers from the surgical center to the hospital. In addition, any urgent care or emergency room visits and hospital admissions for the first month after surgery were tabulated. Points of review of the patients’ postoperative course included the following: (1) phone contact on the first postoperative day, (2) routine ASC postoperative phone calls two to three days postoperatively, (3) first postoperative office at approximately one to two weeks, and (4) phone contact or office evaluation one-month postoperatively based on surgeon preference for follow-up.ResultsA total of 583 patients were identified for participation, of whom 22 patients were excluded; thus, 561 patients were included for evaluation, with 47.2% women (n=265) and 52.8% men (n=296). The average age was 54 years (range: 14-102 years). Nine (1.6%) patients presented postoperatively for further evaluation at an urgent care or hospital (95% C.I. 0.8-3.1%). Five patients presented to an emergency room and four patients presented to an urgent care facility. Of those patients, two were admitted to the hospital due to shortness of breath (0.35%; 95% CI: -0.08 to 1.4%). Emergency room and urgent care visits that did not lead to admission accounted for 1.25% (95% CI: 0.6-2.6%). No patients were transferred from the ASC to the hospital or emergency room.ConclusionThere was a low rate of postoperative utilization of urgent care and emergency room services with hand and upper extremity surgery performed at free-standing, ASCs. Hospital readmissions were rare, and no patients required transfer from an ambulatory care center to the hospital. Outpatient hand and upper extremity surgery is safe in an ambulatory care center, with low postoperative transfers and readmissions in the month following surgery.
