    Abstract:
    BACKGROUND: Interest in postoperative healthcare utilization has increased following the implementation of episode-of-care funding for elective orthopedic surgery. Most efforts have focused on readmission; however, little has been reported on emergency department (ED) presentation. We analyzed elective, primary total hip or knee arthroplasty (THA and TKA) cases to determine the rate, reasons, risk factors, timing, and hospital cost associated with 30-day ED presentations. METHODS: An observational study of patients who underwent primary, elective TKA and THA between January 1, 2016, and December 31, 2017, was performed. The primary outcome was an ED visit within 30-days of the index operation. Secondary outcomes included reasons, risk factors, timing, and hospital cost of ED visits. A multivariable logistic regression was undertaken to determine patient factors associated with ED presentation. RESULTS: Overall, 1690 patients were included, of which 9.2% presented to the ED within 30-days of surgery. Approximately two-thirds of the visits were after-hours, and most were discharged home without readmission (81.4%). The most commonly reported reasons were wound concerns (30.1%) and pain (20.5%). Older age (OR 1.1, P = .03) and preoperative dyspnea (OR 2.1, P < .001) increased the odds of ED visits. The mean cost of an ED visit was significantly greater after-hours (P = .015). CONCLUSION: Overall, 1 in 10 patients undergoing TKA/THA presented to the ED within 30-days of surgery, of which over 80% were not readmitted, and most occurred after-hours where cost is greatest. Our observations suggest ED visits following TKA/THA are common, and most are likely preventable. Future efforts should focus on developing interventions to reduce these visits.
