The Effects of Opioid Use on Thromboembolic Complications, Readmission Rates, and 90-Day Episode of Care Costs After Total Hip Arthroplasty
Sodhi, Nipun et al.Hip
Background
The purpose of this study was to investigate whether opioid use disorder (OUD) patients are at greater odds than non–opioid use disorder (NUD) patients in developing (1) thromboembolic complications; (2) readmission rates; and (3) costs of care.
Methods
All patients with a 90-day history of OUD before total hip arthroplasty (THA) were identified from a national database. Patients were matched 1:5 to controls by age, gender, Elixhauser Comorbidity Index scores, and high-risk medical comorbidities, yielding 38,821 patients with (n = 6398) and without (n = 31,883) OUD. Multivariate logistic regression analyses were performed to compare the risks of developing venous thromboembolism (deep vein thrombosis and/or pulmonary embolism) 90 days after the index procedure, 90-day readmission rates, and total global 90-day episode of care costs.
Results
Patients with a history of OUD were found to be at greater risk for 90-day venous thromboembolisms (2.38 vs. 1.07%; OR: 2.25, 95% CI: 1.86-2.73, P < .0001) compared with matched NUD patients. Specifically, OUD patients were at greater risk for both deep vein thromboses (2.13 vs. 0.87%; OR: 2.46, 95% CI: 2.00-3.03, P < .001) and pulmonary embolism (0.61 vs. 0.27%; OR: 2.24, 95% CI: 1.53-3.27, P < .0001). In addition, patients with OUD were at an increased risk for 90-day readmission (28.68 vs. 22.62%; OR: 1.37, 95% CI: 1.29-1.46, P < .0001) compared with controls. Primary THA patients with OUD incurred a 14.72% higher cost of care ($20,610.65 vs. $17,964.58) compared with NUD patients.
Conclusion
These findings demonstrate that primary THA patients with a history of OUD are at greater risks for thromboembolic complications, readmissions, and higher costs of care in the 90-day postoperative period.
