    Preoperative opioid use is linked to increased risks for complications, longer hospital stays, and higher readmission rates following total hip arthroplasty.

    The NarxCare Overdose Risk Score (ORS) provides a nuanced measure of prescription drug use, considering multiple factors beyond simple drug use presence.

  • 3

    A NarxCare ORS exceeding 100 correlates with poorer improvements in patient-reported outcome measures (PROMs) after total hip arthroplasty.

  • 4

    The study analyzed 5424 patients who underwent primary total hip arthroplasty, excluding those with missing data or lost to follow-up.

    Primary outcomes included achieving Minimum Clinically Important Difference (MCID) and Patient Acceptable Symptom State (PASS) thresholds in PROMs at one year.
