简要总结
Pain is a major risk factor for chronic postoperative pain. Adequate perioperative pain relief is an important metric for patient satisfaction and to achieve good recovery outcomes. Opioids remain the primary systemic pharmacotherapy for intraoperative and postoperative analgesia, particularly for moderate to severe pain. When used judiciously, opioids are effective in reducing suffering and helping patients cope with postoperative pain. However, there are challenges - a) side effects can result in harm, like respiratory depression; b) over-reliance on opioids can increase drug dependency; c) over-prescription can encourage addiction, overdose and death, leading to a human and financial burden from both, an individual, and public health standpoint. Over-prescription of opioids for acute pain is strongly linked to patient morbidity and mortality. For example, a new opioid prescription raises the risk of lethal or non-lethal overdose, as well as the conversion from opioid-naive to chronic user. Canadian Institute of Health Information (CIHI), and Public Health Agency of Canada (PHAC) data emphasize the public health need to reduce reliance on opioids: "From January 2016 to June 2018, more than 9,000 Canadians died from apparent opioid related harms. In 2017, an average of 17 Canadians were hospitalized for opioid poisonings each day - an increase from 16 per day in 2016". Prescription opioid use appears to be an early driver of the current crisis. Given the local and national severity of the opioid crisis, there is need for a pragmatic, timely, and scalable intervention to reduce reliance on opioids as we strive to improve healthcare for patients and alleviate the economic burden on the medical system. This proposal for a stepped-wedge randomized trial of a multi-faceted opioid-use reduction strategy addresses key drivers of the opioid crisis and has the potential to reduce patient exposure to opioids and, thereby, improve morbidity and mortality. Hospitals involved in this study will all eventually participate in an opioid reduction strategy that will limit the access and prescription of opioids to surgical patients and will incorporate various opioid reduction strategies at both a patient and hospital level.
详细描述
Proposed Trial Design The proposed prospective randomized trial will employ a stepped-wedge design, which is a variant of a cluster randomized trial. This is a pragmatic, two-armed, parallel group registry based, cluster RCT. This SWAHN associated hospitals trial will be embedded into routine care (new standard of care) with implementation of the intervention delivered by perioperative personnel rather than research staff. Patient characteristics and outcomes will be obtained from ICES administrative health care database. This pragmatic design allows broad inclusion of the south west LHIN hospitals and a large representative sample of perioperative patients that should yield highly generalizable findings. The hospitals will be randomized (1:1) with concealed allocation methods and hospitals will be notified of their group allocation by the study team 2 months before the intervention start date.
In this trial, the unit of randomization is the cluster (i,e each of the hospital) and the unit of analysis is the patient. The investigators chose a cluster randomized design to enhance intervention uptake and adherence (logistical convenience) and to minimize cross-group contamination. Perioperative patients typically receive all their intervention at the same centre, making this population suitable for cluster-level interventions. Delivery of the opioid reduction strategy intervention in this cluster trial follows what occurs in routine care, where the perioperative team in each hospital will be trained to follow the same protocol or policy for patients under their care.
This will entail the roll out of the intervention in a randomized fashion and "sequential crossover of clusters from control to intervention until all clusters are exposed". This type of trial is a pragmatic approach to investigate and implement a service delivery change, given that the intervention will occur at the institutional level and individual patients will not need to be randomized.
This multi-centre, stepped-wedge cluster- RCT is designed to evaluate the benefits of an opioid reduction strategy compared to standard practice as per local hospital protocol, in patients undergoing elective surgical procedures, who are prescribed opioids to control acute post- operative pain. In order to overcome data collection challenges, the investigators will collect the outcomes from all elective surgical patients (no exclusions) from electronic databases ICES for the pre- and post-intervention. Following a 2-month baseline period in which all sites use their usual standard-of-care opioid prescription, one of the randomly selected sites will begin implementing and following the opioid reduction strategy; other sites will be randomly added to the intervention group every two months until the strategy is in place at all the sites (total 12 months of data collection). One month before crossover to the phase of opioid reduction strategy at each site, all anesthesia and research staff at the hospital site will be trained by the study PI (Mahesh Nagappa) on the various intervention components, on implementing the opioid reduction strategy, and on collection of data.
Twelve hospitals within the Southwestern Ontario Academic Hospital Network (SWAHN) will be invited to participate. London Health Sciences Centre and St. Joseph's Healthcare London will be the lead sites. For this study, we have selected the perioperative setting in which opioid analgesia prescribing is common during the hospital discharge.

盲法说明
It is not possible to blind clinicians or study staff to hospital allocation because the appropriate pain/opioid management must be transparently applied upon entry to the intervention phase of the study, and therefore the unit of randomization is at the hospital level. Outcome adjudicators will be blinded and patients will remain blinded.
