Day of Surgery Admission in Total Joint Arthroplasty: Why Are Surgeries Cancelled? An Analysis of 3195 Planned Procedures and 114 Cancellations.

. Day of surgery admission (DOSA) is becoming standard practice as a means of reducing cost in total joint arthroplasty. . The aim of our study was to audit the use of DOSA in a specialty hospital and identify reasons for cancellation. . A retrospective study of patients presenting for hip or knee arthroplasty between 2008 and 2013 was performed. All patients were assessed at the preoperative assessment clinic (PAC). . Of 3195 patients deemed fit for surgery, 114 patients (3.5%) had their surgery cancelled. Ninety-two cancellations (80%) were due to the patient being deemed medically unsuitable for surgery by the anaesthetist. Cardiac disease was the most common reason for cancellation ( = 27), followed by pulmonary disease ( = 22). 77 patients (67.5%) had their operation rescheduled and successfully performed in our institution at a later date. . DOSA is associated with a low rate of cancellations on the day of surgery. Patients with cardiorespiratory comorbidities are at greatest risk of cancellation.
