title: The Incidence of Subsequent Surgery After Outpatient Arthroscopic Rotator Cuff Repair.
abstract: To quantify the incidence and risk factors associated with subsequent shoulder procedures in individuals undergoing outpatient arthroscopic rotator cuff repair (ARCR).
  
  
  
  We examined the New York Statewide Planning and Research Cooperative Systems outpatient database from 2003 through 2014 to identify patients undergoing isolated ARCR with or without concomitant acromioplasty. Patients were longitudinally followed up for a minimum of 2 years to determine the incidence of subsequent ipsilateral shoulder surgery. The impact of age, sex, insurance, concomitant acromioplasty, and tobacco use on reoperation was explored.
  
  
  
  Between 2003 and 2012, 30,430 patients underwent isolated ARCR. The mean age was 56.6 ± 11.5 years, and 55.1% were male patients. A total of 1,826 patients (6.0%) underwent subsequent ipsilateral outpatient shoulder surgery a mean of 24.3 ± 27.1 months after the initial ARCR. Of patients who underwent repeat surgery, 57.3% underwent a revision cuff repair. Patients who underwent additional outpatient shoulder surgery were significantly younger (53.7 ± 10.9 years v 56.8 ± 11.5 years, P < .001). Tobacco use was associated with an increased rate of subsequent surgery (7.3% v 5.9%, P = .044) and accelerated time to reoperation (16.9 months v 24.7 months, P < .001). Independent risk factors for subsequent ipsilateral surgery after initial ARCR were presence of a Workers' Compensation claim (odds ratio, 2.11; 95% confidence interval, 1.89-2.36; P < .001) and initial ARCR without acromioplasty (odds ratio, 1.20; 95% confidence interval, 1.09-1.34; P < .001).
  
  
  
  We identified a 6.0% incidence of repeat ipsilateral surgery after isolated ARCR. Although reasons for reoperation are likely multifactorial, younger age, Workers' Compensation claim, and absence of acromioplasty at the time of initial ARCR remained independent predictors of subsequent outpatient procedures, whereas a history of tobacco use was associated with accelerated time to subsequent surgery.
