Abstract

Study design: Retrospective case-controlled study. Objectives: To analyze the overall performance and outcome of two-a-day surgery days for adolescent idiopathic scoliosis (AIS). Summary of background data: As a method to improve efficiency and operating room utilization, some surgeons are now performing two surgeries for AIS in a single day. Methods: A prospectively collected series of AIS patients who underwent posterior spinal fusion on the same day as a second AIS patient by the same surgeon and surgical team were retrospectively reviewed. Patients who underwent same-day surgery (SD) were grouped according to whether they were the first (SD1) or second (SD2) case of the day and were matched (M1 and M2) by surgeon, curve magnitude, Lenke classification, and fusion levels. Comparisons were made: SD1 vs. SD2, SD1 vs. M1, and SD2 vs. M2. Results: There were 56 patients, with no differences between groups in age, gender, BMI, or curve magnitude (66° vs. 62° vs. 65° vs. 63°). Surgical time was shorter for the SD1 group (17.2 min/level) compared to M1 (20.5 min/level) for a 15% operative time reduction of 44 min (p = 0.008). There were no differences between the groups in curve correction (65.8% vs. 62.8% vs. 66.1% vs. 58.5%), estimated blood loss (EBL), length of stay, or complication rate. One SD2 patient had a malpositioned screw that required revision. There were no other complications. Conclusions: When performing two AIS surgeries on the same day, surgical time was reduced by 44 min, or 15%, on the first case compared to a matched control. This may be a reflection of the team moving along more efficiently, given the full operative day scheduled. The performance measures of curve correction, EBL, complications, and length of stay did not decline in this new model, and no increased incidence of complications was seen.
