Surgeons in Michigan have reduced the amount of opioid medication prescribed to patients recovering from common operations by nearly a third -- without causing patients to feel more postoperative pain.
In a new research letter published in the New England Journal of Medicine, a team from the Michigan Opioid Prescribing Engagement Network (OPEN) reported on the results of a statewide effort to get surgical teams to follow prescribing guidelines for postoperative pain.
In just one year, surgeons at 43 Michigan hospitals reduced the number of opioid pills prescribed to patients after nine common operations, from an average of 26 pills per patient to an average of 18.
The surgeries included minor hernia repair, appendix and gallbladder removal, and hysterectomies. Most were minimally invasive laparoscopic surgeries.
The ratings patients gave for their post-surgical pain and satisfaction didn't change from the ratings given by patients treated in the six months before opioids were reduced.
Researchers say patients only took about half the opioids prescribed to them, even as the prescription sizes shrank. They attribute this to improved counseling about pain expectations and non-opioid pain control options.
"The success of the statewide effort suggests an opportunity for other states to build on Michigan's experience, and room for even further reductions in prescription size," said Michael Englesbe, MD, a University of Michigan surgery professor. "At the same time, we need to make sure that patients also know how to safely dispose of any leftover opioids they don't take."
The study involved over 11,700 patients who had operations at hospitals participating in the Michigan Surgical Quality Collaborative. About half of the patients also filled out surveys sent to their homes after their operations, asking about their pain, satisfaction and opioid use after surgery.
The Michigan-OPEN team has been working since 2016 to reduce opioid prescribing and quantify the appropriate number of pills patients should take. Their research led to the the development of new guidelines that were first tested on gallbladder surgery patients before being expanded to other types of surgery.
Some hospitals have stopped giving opioids to surgical patients. Patients at Cleveland Clinic Akron General Hospital get acetaminophen, gabapentin and nonsteroidal anti-inflammatory drugs (NSAIDs) to manage their pain before and after colorectal operations – and their surgeons say the treatment results in better patient outcomes
It’s a common misconception that many patients become addicted to opioids after surgery. A 2016 Canadian study, for example, found that long term opioid use after surgery is rare, with less than one percent of older adults still taking opioid pain medication a year after major elective surgery.
Another large study in the British Medical Journal found similar results. Only 0.2% of patients who were prescribed opioids for post-surgical pain were later diagnosed with opioid dependence, abuse or a non-fatal overdose.
Another fallacy is that leftover pain medication is often stolen, sold or given away. The DEA says less than one percent of legally prescribed opioids are diverted.
