Post-Traumatic Stress Disorder Is Associated With Increased Emergency Department Services and Similar Rates of Opioid Prescriptions Following Primary Total Hip Arthroplasty: A Propensity Matched Analysis.

Background: There is a paucity of literature regarding patients who have post-traumatic stress disorder (PTSD) following primary total hip arthroplasty (THA). The purpose of this study was to compare the rates of postoperative complications, prescriptions, health care utilization, and revision arthroplasty of patients who had PTSD undergoing primary THA against a propensity matched control group of patients who did not have PTSD (NPTSD).

Methods: The TriNetX database was queried to identify PTSD patients undergoing primary THA. Patients were then propensity matched in a 1:1 ratio based on twelve preoperative characteristics to a cohort of NPTSD patients. Postoperative prescriptions and rates of health care utilization were analyzed within 5 days, 14 days, and 1 month postoperatively. Complications were analyzed within one month. Revision arthroplasty rates were analyzed within 1 year and 2 years.

Results: A total of 198,560 patients undergoing primary THA were identified. Ultimately, 1,310 PTSD patients were successfully propensity matched to a cohort of 1,310 NPTSD patients. Patients who have PTSD presented to the emergency department at significantly higher rates than NPTSD patients within 14 days and 1 month postoperatively. Within 1 month postoperatively, cohorts were prescribed opioid analgesics at similar rates (P = .709). Patients who had PTSD received more prescriptions per patient compared to NPTSD patients. Patients who had PTSD were also found to have a higher number of total complications per person within 1 month (P = .022). Within 2 years postoperatively, rates of revision hip arthroplasty were comparable between cohorts (P = .912).

Conclusions: Patients who have PTSD experience similar rates of revision hip arthroplasty and opioid prescribing compared to NPTSD patients following primary THA; however, within 1 month postoperatively, emergency department visits were greater in PTSD patients. These findings can help delineate early postoperative education and expectations for patients who have PTSD in contrast to other psychiatric diagnoses.
