About this study

Official title: A Prospective, Randomized Trial of the Effect of Standard of Care Reduced Dose Versus Full Dose Buprenorphine/Naloxone in the Perioperative Period on Pain Control and Post Operative Opioid Use Disorder Symptoms

The aim of this study is to determine the effect of continuation of buprenorphine/naloxone in patients with history of Opioid Use Disorder (OUD) scheduled for surgery compared to reduced dose buprenorphine/naloxone prior to surgery on pain scores, opioid consumption, depressive symptoms and severity of substance use dependence- including record of problematic use of any non-prescribed opioids, alcohol and illicit narcotics.

Read the detailed description

Opioid use disorder (OUD) is characterized by non-remitting cycles of remission and opioid abuse relapse. It is associated with a high rate of psychiatric and physical co-morbidity when left untreated. Buprenorphine and buprenorphine/naloxone are effective opioid maintenance therapy (OMT) for OUD, however, treatment of acute post-surgical pain in patients taking buprenorphine is perceived to be challenging. Although not substantiated in clinical studies, the combination of high receptor binding affinity, long half-life, and partial mu opioid receptor agonism with buprenorphine/naloxone are thought to inhibit the analgesic actions of full mu opioid receptor agonists, potentially making standard postoperative pain control strategies less effective. There is no evidence based standard of care for optimal acute pain management strategies for patients taking buprenorphine and most recommendations are based upon provider opinion- occasionally conflicting along specialty lines. Some providers, mainly consisting of surgeons and anesthesiologists, recommend that buprenorphine should be discontinued at least 72 hours prior to elective surgery and replaced with low dose opioid agonists, in the interim. Other providers, mainly comprising of psychiatrists, contend that these patients should be maintained on buprenorphine throughout the peri-operative period at either a full or reduced dose to prevent an indeterminate risk of substance abuse relapse that can occur as consequence to the abrupt termination buprenorphine in the highly stressful surgical period. This study aims to inform this important unresolved question in the clinical care of this growing population. The investigators seek to determine the effectiveness of managing postoperative pain in patients with OUD where buprenorphine/naloxone is continued perioperatively compared to patients where buprenorphine/naloxone is reduced to a lower dose. Longitudinally, the investigators also intend to determine if there is a difference in substance abuse relapse in patients where buprenorphine/naloxone is continued vs. held by using self assessments and communication with the participant's buprenorphine provider.

    Also called Reduction vs Continuation

    The intervention will be to either continue taking buprenorphine/naloxone or to have the medication reduced perioperatively.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Post-operative pain scores

    Level of pain on a Visual Analog Scale of 0-100 (0=no pain; 100=worst pain imaginable) This scale will be used to quantify the varying degrees of pain or discomfort experienced by the participant.

    Measured: 24 hours after surgery

Secondary outcomes (3)
  1. Postoperative opioid consumption

    Amount of opioids needed for pain control postoperatively

    Measured: 24 hours, 48 hours and 72 hours after surgery

  2. Post-operative pain scores

    Level of pain on Visual Analog Scale 0-100 (0= no pain 100= worst pain imaginable) We will compare the results of the 48 and 72 hour time-points with the 24 hour time-point.

    Measured: 48 hours, 72 hours after surgery

  3. Presence, severity of substance abuse

    Participants will complete questionnaires to identify the presence and severity of substance abuse.These values will be compared with baseline values obtained preoperatively.

    Measured: 1 month after surgery
