NCT07348627

Brief Summary

The goal of this clinical trial is to evaluate whether an opioid-sparing postoperative pain regimen can reduce opioid consumption and maintain effective pain control in adults undergoing anterior total hip arthroplasty for osteoarthritis. The main questions it aims to answer are:

  • Does an opioid-limited regimen result in lower postoperative opioid use compared with a standard opioid prescription?
  • Does the opioid-limited regimen provide comparable or improved postoperative pain control and patient satisfaction?

Outcome Measures

Primary Outcomes (6)

  • Daily Pain Scores (Numeric Rating Scale, NRS)

    A 0-10 numeric scale used to assess pain intensity. Participants rate their pain three times daily during the first postoperative week. Mean daily pain scores will be compared between groups. High scores: greater pain intensity. Low scores: better pain control.

    Postoperative Days 1-7

  • Opioid Consumption (Morphine Milligram Equivalents, MME)

    Total opioid use, including study medication, rescue hydromorphone, and any additional prescriptions, will be converted to MME to quantify postoperative opioid consumption.

    1 week, 3 weeks, and 3 months postoperatively

  • Pain-Related Contacts to Clinical Team

    Number of calls or electronic messages to the surgical team related to pain management.

    Up to 3 months postoperatively

  • Medication-Related Side Effects

    Incidence and severity of nausea, constipation, vomiting, or other adverse effects associated with postoperative pain medications.

    Postoperative Days 1-7

  • Opioid Prescription Refills

    Number of opioid prescription refills requested or obtained after surgery.

    Up to 3 months postoperatively

  • Patient Satisfaction With Pain Control

    Patient-reported satisfaction with postoperative pain control, rated on a 5-point scale (much worse than expected to much better than expected).

    1 week, 3 weeks, and 3 months

Secondary Outcomes (8)

  • Patient-Reported Outcomes (PROMs): HOOS Jr

    Baseline (preoperative) and at 3 months

  • Patient-Reported Outcomes (PROMs): EQ-5D (EuroQol-5 Dimensions)

    Baseline (preoperative) and at 3 months

  • Patient-Reported Outcomes (PROMs): Subjective Hip Value (SHV)

    Baseline (preoperative) and at 3 months

  • Patient-Reported Outcomes (PROMs): Pain Catastrophizing Scale (PCS)

    Baseline (preoperative) and at 3 months

  • Postoperative Nausea (VAS-Nausea)

    Postoperative Days 1-7

  • +3 more secondary outcomes

Study Arms (2)

Opioid-Sparing Regimen

EXPERIMENTAL

Participants receive a standardized multimodal non-opioid analgesic regimen throughout the perioperative period and are discharged with placebo tablets instead of a standard opioid prescription. All participants receive counseling from a Life Care Specialist and a limited supply of rescue hydromorphone for severe breakthrough pain.

Drug: PlaceboOther: Multimodal Non-Opioid Analgesia

Standard Opioid Prescription

ACTIVE COMPARATOR

Participants receive the same standardized multimodal non-opioid analgesic regimen and Life Care Specialist counseling as the experimental group, but are discharged with a standard opioid prescription.

Drug: Oxycodone 5 mgOther: Multimodal Non-Opioid Analgesia

Interventions

* 28 tablets identical in appearance to 5-mg oxycodone * Taken 1-2 tablets every 4 hours as needed for moderate to severe pain * Dispensed by Investigational Drug Services * Used in combination with standardized multimodal analgesia

Opioid-Sparing Regimen

* 28 tablets of 5-mg oxycodone * Taken 1-2 tablets every 4 hours as needed for moderate to severe pain * Represents standard postoperative prescribing practi

Standard Opioid Prescription

Multimodal Non-Opioid Analgesia (Standardized Regimen) Includes: * Acetaminophen * Meloxicam * Methylprednisolone taper * Spinal anesthesia * Periarticular local anesthetic injection * Postoperative scheduled acetaminophen and NSAIDs * Counseling by Life Care Specialist * Two 2-mg hydromorphone tablets for rescue only
