Clinical Trial Summary

North America is facing an opioid epidemic fueled by surgeons, who are the second largest subgroup of physicians involved in opioid prescribing. Surgery often serves as the initial event for opioid-naïve patients to obtain a prescription for opioids and spiral into misuse and addiction. From the perspective of perioperative care clinicians, the answer to the opioid crisis may be using opioid-free analgesia. However, the number of comparative studies in this field is limited and existing small trials do not reflect current standards of care in North America. Lack of evidence means that the decision to prescribe opioids after outpatient surgery largely depends on surgeon preference and healthcare culture. Hence, there is an urgent need for a robust randomized controlled trial (RCT) to guide clinical decision-making. The feasibility and optimal design of this RCT should be informed by a pilot trial. The overarching goal of this pilot RCT is to investigate the feasibility of conducting a full-scale RCT to assess the comparative-effectiveness of opioid versus opioid-free analgesia after outpatient general surgery.


Clinical Trial Description

This study will be a pragmatic, parallel, two-group, assessor-blind, pilot RCT. The investigators aim to recruit 80 adult patients at two tertiary hospitals in Montreal. Eligibility criteria will span outpatient procedures in abdominal and breast surgery. Patients are randomized on a 1:1 ratio to treatment with either opioid (standard care) or without opioid (only non-opioid analgesics). Patients will be followed up for 3 months after surgery; postoperative day (POD) 1 to POD 7 and at 2, 3 and 4 weeks after surgery, and at 3 months. Assessments will include postoperative pain, physical and mental function, adverse drug events, prolonged opioid use and opioid misuse. Feasibility outcomes will include the number of patients screened, consented and randomized, adherence with treatment and completion of follow-up. Data from this pilot study will inform the calculation of sample size requirements for the full-scale RCT. An embedded qualitative study will be conducted to help optimize trial design based on clinicians' and patients' perspective. ;
