Evaluation of Open-Label Conditioned Placebo Analgesia for Postoperative Opioid Reduction Following Spinal Fusion (COLP)

September 9, 2021 updated by: Kristin Schreiber, Brigham and Women's Hospital
This research aims to understand the impact of conditioned open label placebo (COLP) on opioid consumption and pain after surgery. The hypothesis being tested is that by pairing a non-deceptive placebo pill with regularly prescribed pain killers after surgery, will allow reduction in opioids taken while maintaining the same level of analgesia.

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

Participants will be enrolled at preoperative clinic.

Inclusion criteria:

  1. aged 18-75 years
  2. scheduled for spinal fusion surgery
  3. able to comprehend and willingness to participate in COLP
  4. willingness to undergo psychophysical and psychosocial testing
  5. willingness to participate in long-term follow-up.

Exclusion criteria:

  1. delirium, psychosis, or other cognitive impairment limiting completion of study procedures
  2. non-English speaking
  3. contraindication to opioid usage

Preoperative psychosocial and pain questionnaires will be completed using a secure email link to REDcap, and brief quantitative sensory testing performed.

After completion of preoperative testing, they will be randomized to one of 2 treatments: COLP or treatment as usual (TAU).

Day of surgery: Patient will undergo scheduled spinal fusion and admitted for post-operative recovery as per normal surgical management. No restrictions on intraoperative anesthetics or post-operative pain management options will be made. Intraoperative medication use, including opioids, as well as post-operative opioid consumption and pain scores will be extracted from the medical record.

Inpatient and outpatient postoperative period: The study investigator or research assistant (RA) will train the participant and nursing staff in the self-administration of COLP with each analgesic administration in hospital, beginning on POD 0, pairing one open label placebo pill with each analgesic medication administration. Beginning on POD 2, patients will additionally be instructed to take a scheduled placebo pill at least 3 times/day, and in conjunction with their ongoing instances of PRN opioid utilization. Opioid administration and pain scores will be recorded in a daily diary, which the RA will help fill out on POD1 and 2 with them. At hospital discharge, the patients' bottle of placebo pills will be replenished. Patients will be instructed to continue scheduled and PRN use of opioids, and encouraged to use placebo pills. After discharge, the number of placebo and opioid pills that they use, as well as average pain at rest and with movement each day will be collected for up to 21 days via email linking to Redcap system. If preferred, patients will answer questions through daily SMS TEXT or telephone call, using a secure study phone. To protect patient's privacy there will be no identifiable information in the text messages. The SMS texts will be sent from a dedicated study phone that is MobileIron enabled. MobileIron is software used by Partners HealthCare that allows for more secure data management.

Follow-up visit: At surgical follow-up visit, patients will repeat baseline testing and participants in the COLP group will undergo a 15-minute semi-structured interview to determine the patient's experience with managing post-operative pain with COLP. Long term follow-up on pain, psychosocial impact and opioid use will be accomplished using the Redcap email survey system.

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.
