Multimodal Analgesic Regimen for Total Hip Arthroplasty: An Initiative to Minimize Postoperative Opioid Use

June 22, 2026 updated by: Michael Charters, MD, Henry Ford Health System
This study examines whether patients undergoing total hip replacement surgery can manage their pain effectively while using fewer opioid pain medications. Participants will be randomly assigned to one of two groups. The first group will receive the standard postoperative pain medication regimen, with all prescriptions sent directly to their pharmacy as usual. The second group will receive the same medications, but their opioid prescription will only be provided as a printed copy rather than being sent directly to the pharmacy, requiring them to choose whether to fill it. All participants will keep a pain journal and complete questionnaires about their medication intake over the first 21 days post-op as well as there function and wellbeing at follow up visits over 3 months. The goal is to determine whether this approach reduces opioid use while still adequately controlling pain after hip replacement surgery.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Standard Postoperative Pain Protocol (Control)
Participants receive the standard postoperative multimodal pain regimen following primary total hip arthroplasty. All prescriptions, including opioids, are sent directly to the patient's pharmacy per usual care. Participants complete a postoperative pain journal, medication log, respond to phone/text check-ins regarding pain scores, and complete PROMIS, HOOS Jr., and Harris Hip Score questionnaires at follow-up visits postoperatively.
Participants receive the standard postoperative multimodal pain regimen following primary total hip arthroplasty. All prescriptions are sent directly to the patient's pharmacy. Opioid consumption tracked via the Michigan Automated Prescription System (MAPS) and patient medication journal. Pain and medication consumption are assessed via daily pain/medication logs daily for the first week, then weekly for two additional weeks.
Experimental: Opioid-Reduced Postoperative Pain Protocol (Treatment)
Participants receive the standard postoperative multimodal pain regimen following primary total hip arthroplasty. Opioid prescriptions (Tramadol) are printed and given to the patient rather than sent directly to the pharmacy, requiring the patient to drive to the pharmacy if they choose to fill them. Participants complete a postoperative pain journal, mediation logs, respond to phone/text check-ins, and complete PROMIS, HOOS Jr., and Harris Hip Score questionnaires at follow-up visits postoperatively.
Participants receive the standard postoperative multimodal pain regimen following primary total hip arthroplasty. Tramadol is prescribed but the prescription is printed and given to the patient rather than sent to the pharmacy, requiring the patient to actively choose to fill it. This behavioral barrier is designed to reduce opioid consumption while preserving patient autonomy. Pain and medication intake is assessed via daily pain journals and medication logs for the first week, then weekly for two additional weeks. Opioid consumption is also tracked via the Michigan Automated Prescription System (MAPS).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Postoperative Pain Score (Visual Analog Scale)
Time Frame: Preoperative baseline through 3 weeks postoperatively
Pain severity measured using a visual analog scale (VAS) scored 0-10, where 0 represents no pain and 10 represents the worst possible pain. Scores collected preoperatively, daily during inpatient admission, daily for the first week post-discharge, then weekly for 2 additional weeks via patient pain journal and phone/text check-ins.
Preoperative baseline through 3 weeks postoperatively
Postoperative Nausea Score (Visual Analog Scale)
Time Frame: Preoperative baseline through 3 weeks postoperatively
Nausea severity measured using a visual analog scale (VAS) scored 0-10, where 0 represents no nausea and 10 represents the worst possible nausea. Scores collected preoperatively, daily during inpatient admission, daily for the first week post-discharge, then weekly for 2 additional weeks via patient pain journal and phone/text check-ins.
Preoperative baseline through 3 weeks postoperatively
Opioid Consumption
Time Frame: Three weeks post-op
Total opioid consumption measured in morphine milligram equivalents (MME) and by dose and quantity. Inpatient opioid use collected via electronic medical record and the Michigan Automated Prescription System (MAPS). Post-discharge opioid use recorded by the patient in a postoperative pain journal.
Three weeks post-op
Antiemetic Consumption
Time Frame: three weeks postoperatively
Total antiemetic consumption recorded by dose and quantity. Inpatient use collected via electronic medical record; post-discharge use recorded by the patient in a postoperative pain journal.
three weeks postoperatively
Length of Hospital Stay
Time Frame: Perioperative/Periprocedural
Total number of days from surgical admission to hospital discharge following primary total hip arthroplasty.
Perioperative/Periprocedural
Episodes of Nausea
Time Frame: Three weeks postoperatively
