title: Utilization of Total Joint Arthroplasty in Physician-Owned Specialty Hospitals vs Acute Care Facilities.
abstract: The recent emergence of physician-owned specialty hospitals has sparked controversy about overutilization. Thus, the purpose of this study was to compare utilization patterns of total joint arthroplasty (TJA) between physician-specialty hospitals (PSHs) and acute care hospitals (ACHs).
  
  
  
  A retrospective study was conducted from January 2010 to August 2014 comparing primary TJA patients between a PSH and an ACH; 103 PSH patients were matched to 103 ACH patients by age, gender, BMI, and ASA classification with similar case distribution between facilities. All surgeons in the study operated at both hospitals and were shareholders of the PSH. Information on nonoperative treatments, and timing to the initial appointment, consent, and surgery were analyzed using univariate analysis.
  
  
  
  Nonoperative treatments before surgery were similar between hospitals (P = 1.00). The time from the initial appointment to consent was longer for PSH (P = .0001). However, the time from consent to the date of surgery (P = .04) and the timing from symptoms to initial appointment (P = .006) was shorter for PSH. The time from initial appointment to the day of surgery was similar between groups (P = .20). Patients were more likely to be consented for surgery on their first clinic visit when undergoing surgery at ACH (87 of 103, 84.4%) compared to PSH (61 of 103; 59.2%; P < .001). Length of stay was significantly shorter for both total knee arthroplasty (P = .001) and total hip arthroplasty patients (P = .001) at PSH.
  
  
  
  Facility ownership in PSH resulted in similar conservative treatment before TJA. The time to surgical consent after the initial appointment was longer PSH, whereas the time from consent to the date of surgery was shorter at the PSH.
