The study find that Surgeons wielding their life-saving scalpels, laparoscopic tools, or other implements to repair or remove what ails their patients understand all too well that pain is an unavoidable part of the healing process. Yet the current opioid crisis has made the standard prescribing practices for these highly effective analgesics fraught with risk. New research from Michigan Medicine could help clinicians mitigate that risk by identifying which patients are more likely to continue to use opioids after their immediate recovery period.

The current opioid crisis

“There is not much research on which surgical patients require more or less opioids; despite a push in the field for personalized medicine;” says first author Daniel Larach, M.D., M.T.R., M.A.; a resident at U-M at the time of the study and now assistant professor of clinical anesthesiology at the University of Southern California. “Often with postoperative opioid prescribing, personalization falls by the wayside; with surgeons using the same amounts for every person receiving a certain procedure.”

He and the study team looked at data for more than 1,000 people undergoing an elective hysterectomy, thoracic surgery, or a total knee or hip replacement. Before their procedures; each patient provided demographic information and filled out several screening questionnaires. They are give scores measuring their degree of depression, anxiety, fatigue; sleep disturbance, physical function; as well as the severity of their overall and surgical site pain.

Provided demographic information

The research team also measured how many pills are prescribe per patient. Each patient was then contacted one month following surgery to assess how many opioid pills they had consumed. They found that anxiety is linked with more opioid use; which is disheartening to see but also heartening in the sense that this is something we could potentially target.” Daniel Larach, first author Other patient factors linked to increased opioid use included younger age, non-white race; no college degree, alcohol and tobacco use; and sleep disturbance.

Chad Brummett, M.D., associate professor of anesthesiology and director of anesthesia clinical research and pain research; says people may be knowingly or unknowingly medicating for other conditions. “The only thing we’re giving them is opioids and we’re not giving them alternatives or other options,” he says. For example; patients with high anxiety around the time of surgery could be offered behavioral care or other non-opioid medications for anxiety and resulting pain.

Brummett, senior author on the Annals of Surgery paper; also notes that this study found over prescription of opioids for all surgical procedures and a correlation between the prescription size and use. “I think it is striking that you see once again that the more you prescribe, the more patients take, even after adjusting for all of these other risk factors;” explains Brummett.
