Postoperative Analgesia Intervention With Non-opioid Alternatives (PAIN-Alt) Trial - Breast Surgery

Summary

North America is experiencing a crisis of opioid use and abuse, partially caused by excessive prescribing by doctors. People often receive their first opioid prescription for pain treatment after outpatient breast surgery (i.e., surgery to remove all or parts of the breast(s), where patients leave the hospital the same day). Many patients misuse these drugs and become addicted. Additionally, many of the opioid pills prescribed to patients are left unused and may be misused by family members, friends, or other community members. To prevent this problem, surgeons can avoid prescribing opioids by prioritizing opioid-free analgesia (i.e., pain treatment using only non-opioid interventions). Prescribing only non-opioid pain medications after surgery is very common in many countries outside of North America; however, few studies have assessed whether opioid-free analgesia is as effective as opioid analgesia after breast surgery. Therefore, the main question driving this study is: For patients who undergo outpatient breast surgery, is pain treatment without opioids as good as pain treatment with opioids?

The proposed trial will compare two groups of patients: one group will receive opioids to treat pain after surgery, while the other group will receive only non-opioid medications. The impact of these different medication strategies will be measured on pain intensity, pain interference with daily activities, medication side effects, and other outcomes. An expert team of scientists, surgeons, pain specialists, nurses, and patients has been assembled to maximize the success of this study. The results will provide important information to guide surgeons' decisions to prescribe (or not to prescribe) opioids. If opioid-free analgesia is found to be effective, doctors may be able to substantially reduce opioid prescribing after breast surgery and prevent more people from misusing opioids.

Interventions

OTHER

Opioid Analgesia (OA) [Multimodal analgesia including opioid drugs]

In line with current standard care, discharge prescriptions for this group will include around-the-clock non-opioid analgesics (acetaminophen and/or NSAIDs given at regularly scheduled intervals) and opioid tablets 'as needed' for breakthrough pain (i.e., pain that erupts while patients are already taking analgesics). Non-pharmacological pain interventions (i.e., icepacks, music, meditation.) may be recommended by some surgeons as part of standard practice. Given the pragmatic nature of the trial, the specific around-the-clock analgesia and rescue opioid regimens and other non-pharmacological interventions will be determined by the patient's surgeon discretion considering the breast procedure undertaken, co-morbidities, and patient preference.

OTHER

Opioid-Free Analgesia (OFA) [Multimodal analgesia not including opioid drugs]

Discharge prescriptions for this group will include around-the-clock non-opioid analgesics (acetaminophen and/or NSAIDs). In case of breakthrough pain, rescue analgesia may be provided by (1) using evidence-based non-pharmacological pain interventions (i.e., icepacks, music, and meditation), (2) adding non-opioid drugs not included in the initial regimen, or (3) switching drugs targeting individual variances in analgesia response. The specific around-the-clock and rescue OFA regimens will be determined by the patient's surgeon considering the type of procedure, co-morbidities, and patient preference.
