Predictors of new persistent opioid use after coronary artery bypass grafting

Deaths from prescription opioid overdose have quadrupled in the past 15 years, and no studies have evaluated appropriate opioid prescribing after cardiac surgery. The aim of this study is to quantify the amount of outpatient opioids prescribed to patients after coronary artery bypass grafting and determine the incidence and risk factors for new persistent opioid use after coronary artery bypass grafting. Insurance claim data from privately insured opioid-naïve patients who underwent coronary artery bypass grafting from 2014 to 2016 were evaluated. New persistent opioid use was defined as patients who filled an opioid prescription in the perioperative period and filled opioid prescriptions between 90 and 180 days after surgery. Multivariable logistic regression was used to determine the preoperative and operative factors associated with new persistent opioid use. Among 7292 opioid-naïve patients undergoing coronary artery bypass grafting, 5628 (77.2%) filled opioid prescriptions in the perioperative period, and 590 (8.1%) had new persistent opioid use.
