Two Post-Operative Pain Protocols at Discharge for Orthopaedic Patients

June 23, 2026 updated by: Arun Aneja, MD, PhD, Massachusetts General Hospital

A Pilot Randomized Controlled Trial Comparing Two Post-Operative Pain Protocols at Discharge for Orthopaedic Patients: A Pilot Study

This is a single-center, pilot randomized controlled trial designed to evaluate the feasibility of a definitive trial comparing opioid-free discharge prescriptions to usual care (which includes opioids) in patients undergoing major orthopaedic surgery. The main objective is to inform the design and feasibility of the definitive RCT.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a single-center pilot RCT of at least 100 participants (20 participants from each subspecialty including trauma, arthroplasty, foot and ankle, spine, and sports) who undergo major orthopaedic surgery. Eligible and consenting patients will be randomized to either a discharge pain medication prescription without opioids or a usual care discharge pain medication (with opioids). The overarching objective of the pilot study is to inform the design and feasibility of the definitive RCT. For this pilot trial the investigators will measure feasibility against traffic light criteria based on enrollment metrics, treatment allocation adherence, and on data collection. Furthermore, this pilot RCT will compare the effectiveness of discharge pain medication without opioids to usual care discharge pain medication (with opioids) on opioid use and pain interference for patients who have undergone major orthopaedic surgery.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Discharge pain medication prescription without opioids
The treatment arm will receive standard non-opioid analgesia, with the specific medication (e.g., ibuprofen, paracetamol, ketorolac) determined by the treating physician.
Other: Discharge pain medication prescription
The patients in this pilot RCT will either receive a discharge prescription with or without opioids. The specific non-opioid medication (e.g., ibuprofen, paracetamol, ketorolac) determined by the treating physician. The dosage of the prescription including opioids is also determined by the treating physician.
Active Comparator: Usual care discharge prescription (with opioids)
The control arm will receive the standard pain medication prescription, including opioids. The specific dosage and medication is determined by the treating physician.
Other: Discharge pain medication prescription
The patients in this pilot RCT will either receive a discharge prescription with or without opioids. The specific non-opioid medication (e.g., ibuprofen, paracetamol, ketorolac) determined by the treating physician. The dosage of the prescription including opioids is also determined by the treating physician.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Feasibility of patient enrollment and treatment allocation
Time Frame: From enrollment to the end of the follow-up phase at 6 weeks

Participant enrollment will be assessed by monitoring screening and enrollment metrics, including:

  • Participant enrollment
  • Feasibility of treatment allocation
  • Data collection methods (Proportion of participants with missing data)
  • Compliance with the protocol (Proportion of randomization errors, proportion of patients who complete each questionnaire at each of the follow-up, proportion of patients who withdraw from the trial, proportion of participants who are lost to follow-up)
From enrollment to the end of the follow-up phase at 6 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Opioid Use
Time Frame: From enrollment to the end of the follow-up at 6 weeks
Opioid usage assessed at 2 weeks and 6 weeks post-randomization
From enrollment to the end of the follow-up at 6 weeks
Pain Interference
Time Frame: From enrollment to the end of the follow-up at 6 weeks
Pain interference will be assessed using the Brief Pain Inventory at 2 weeks and 6 weeks from randomization.
From enrollment to the end of the follow-up at 6 weeks
