A 15-Minute Incremental Increase in Operative Duration Is Associated With an Additional Risk of Complications Within 30 Days After Arthroscopic Rotator Cuff Repair

Abstract

Background: Operative time is a risk factor for short-term complications after orthopaedic procedures; however, it has yet to be investigated as an independent risk factor for postoperative complications after arthroscopic rotator cuff repair. Purpose: To determine whether operative time is an independent risk factor for complications, readmissions, and extended hospital stays within 30 days after arthroscopic rotator cuff repair. Study Design: Descriptive epidemiology study. Methods: The American College of Surgeons National Surgical Quality Improvement Program was queried for all hospital-based inpatient and outpatient arthroscopic rotator cuff repairs (Current Procedural Terminology code 29827) from 2005 to 2016. Concomitant procedures such as subacromial decompression, biceps tenodesis, superior labrum anterior and posterior (SLAP) repair, labral repair, and distal clavicle excision were also included, whereas patients undergoing arthroplasty were excluded from the study. Operative time was correlated with patient demographics, comorbidities, and concomitant procedures. All adverse events were correlated with operative time, while controlling for the above preoperative variables, using multivariate Poisson regression with a robust error variance. Results: A total of 27,524 procedures met inclusion and exclusion criteria. The mean age of patients was 58.4 ± 10.9 years, the mean operative time was 86.9 ± 37.4 minutes, and the mean body mass index was 30.4 ± 7.0 kg/m2. Concomitant biceps tenodesis, glenohumeral debridement, SLAP repair, labral repair, and distal clavicle excision significantly increased operative time (P.05). The overall rate of adverse events was 0.88%. After adjusting for demographic and procedural characteristics, a 15-minute increase in operative duration was associated with an increased risk of anemia requiring transfusion (relative risk [RR], 1.27 [95% CI, 1.14-1.42]; P
