Detailed Description
Interventional (clinical trial): Subject will be randomly assigned using permuted blocks (block size of 4). Before usage, random assignments will be created, stored in sealed envelopes, and numbered (1, 2, etc.). There will be stratified randomization: Later on, stratification will be incorporated into the analysis. 32 people will be in the group taking the placebo pills in addition to standardized treatment and 32 people will be in the group with standardized treatment alone.
Hypothesis: Open-label Placebo (COLP) < treatment as usual (TAU) control. Secondary Aims Analysis Plan: There are three secondary aims in this study.
Aim 1. To determine whether 6 weeks of Open-label Placebo (COLP) results in significantly reduced opioid consumption compared to treatment as usual. To test this aim, the investigators will conduct a t-test comparing mean opioid use over the 6 weeks of follow up. In secondary analyses, the investigators will adjust for any baseline factors including gender, age, symptom severity or type of surgery that could be a confounding variable.
1a. To determine if 6 weeks of Open-label Placebo (COLP) results in reduced opioid consumption compared to treatment as usual. Hypothesis: Open-label Placebo (COLP) < treatment as usual (TAU) control.
Secondary Aims Analysis Plan: There are three secondary aims in this study.
Secondary Aim 1: Determine if there are significant differences in time to independence with physical therapy, length of stay, time to return to school, urinary retention, constipation, oxygen requirement, and number of contacts with medical team in Open-label Placebo (COLP) compared to treatment as usual (TAU).
Secondary Aim 2: Determine if there is an association between preoperative pain catastrophization, kinesiophobia, positive/negative affect, anxiety, and/or depression and response to Open-label Placebo (COLP) and/or treatment as usual (TAU).
Secondary Aim 3: Determine if there is an association between postoperative PROMIS scores, anxiety, and/or depression in open-label placebo (COLP) compared to treatment as usual (TAU).
Primary Objectives The primary objectives of this study are to: (1) to determine whether 6 weeks of conditioning with open-label placebo (COLP) results in reduced opioid consumption (amount and duration) compared to treatment as usual (TAU) control and (2) to determine whether 6 weeks of Open-label Placebo (COLP) compared to treatment as usual (TAU) results in different clinical outcomes.
Secondary Objectives
- To determine whether open-label placebo (COLP) affects anxiety and/or depression.
- To determine whether open-label placebo (COLP) affects length of stay, opioid side effects, time to independence with physical therapy, and/or number of contacts with medical team.
- To determine if there is an association between pain catastrophizing, kinesiophobia, and clinical outcomes.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The total amount of opioids consumed in oral morphine equivalents (OMEs) following surgery
Time Frame: from admission to 6 weeks post-operatively
|
Oral morphine equivalents (OMEs) are values that represent the potency of an opioid dose relative to morphine.
Using OMEs provides a standardized method for converting between various opiate medications.
Each oral opioid dose is a 5mg Oxycodone tablet prescribed 6 times per day pro re nata.
Participants will record the number of oral opioids taken each day for 6 weeks following surgery beginning on Post-op Day 1 (POD1).
This data will be collected and converted into OMEs for comparison.
|
from admission to 6 weeks post-operatively
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Weekly level of mobility and change from baseline in mobility on the Patient-Reported Outcome Measurement Information System (PROMIS) Numeric Rating Scale Pediatric Mobility Short Form 7a at week 6.
Time Frame: weekly from admission to 6 weeks post-operatively
|
the PROMIS Pediatric Mobility SF 7a is a validated, self-reported instrument that consists of 7 items rating mobility on average over the past 7 days from 4 (With no trouble) to 0 (not able to do).
Weekly level of mobility = mobility score reported at each week Change = (Week 6 Score - Baseline Score).

|
Weekly level of anxiety and change from baseline in anxiety levels on the Patient-Reported Outcome Measurement Information System (PROMIS) Numeric Rating Scale Anxiety Short Form 8a at week 6.
Time Frame: weekly from admission to 6 weeks post-operatively
|
the PROMIS Anxiety SF 8a is a validated, self-reported instrument that consists of 8 items rating anxiety on average over the past 7 days from 1 (never) to 5 (almost always).
Weekly level of anxiety = anxiety score reported at each week Change = (Week 6 Score - Baseline Score).
|
weekly from admission to 6 weeks post-operatively
|
Weekly level of depressive symptoms and change from baseline in depressive symptoms on the Patient-Reported Outcome Measurement Information System (PROMIS) Numeric Rating Scale Depressive Symptoms Short Form 8a at week 6.
Time Frame: weekly from admission to 6 weeks post-operatively
|
the PROMIS Depressive Symptoms SF 8a is a validated, self-reported instrument that consists of 8 items rating depressive symptoms on average over the past 7 days from 1 (never) to 5 (almost always). Weekly level of depressive symptoms = depressive symptoms score reported at each week Change = (Week 6 Score - Baseline Score). |
weekly from admission to 6 weeks post-operatively
|
The duration of time in days following surgery until patients establish Independence with Physical Therapy
Time Frame: from admission to final physical therapy assessment, up to 6 weeks
|
Participants will be treated by physical therapy services after surgery until their physical therapist determines that they no longer require physical therapy services.
Duration of time to independence with physical therapy is equal to the POD # where physical therapist determines formal PT is no longer required.
|
from admission to final physical therapy assessment, up to 6 weeks
|
The length of time in days following surgery until discharge from the hospital
Time Frame: from admission to discharge, up to 6 weeks

Time Frame: from admission to date of return to school, up to 6 weeks post-operatively
|
Participants will record the date on which they return to school after surgery.

The amount of time it takes to return to school can be used as a proxy for whether participants are struggling with their pain or not.
|
from admission to date of return to school, up to 6 weeks post-operatively
|
Whether participants experience urinary retention following surgery.
Time Frame: during hospitalization until discharge, up to 6 weeks
|
Participants will be assessed in hospital to determine whether or not they experience urinary retention post-surgery, a potential side effect of opioid consumption.
The urinary retention determination will be a yes/no answer.
|
during hospitalization until discharge, up to 6 weeks
|
Whether participants experience constipation measured by the number of days between surgery and first bowel movement
Time Frame: from admission to date of first bowel movement, up to 6 weeks post-operatively
|
Participants will record the number of days between surgery and first bowel movement to assess whether they experience constipation, a potential side effect of opioid consumption.
|
from admission to date of first bowel movement, up to 6 weeks post-operatively
|
Whether participants experience an oxygen requirement and the duration of the requirement following surgery.
Time Frame: during hospitalization until discharge, up to 6 weeks
|
Participants will be assessed in hospital for whether or not they have an oxygen requirement and the duration of requirement.
The oxygen requirement will be a yes/no answer.
