Persistent Opioid Use Among the Elderly After Lung Resection: A SEER-Medicare Study

Background. Opioids represent the mainstay for treating postsurgical pain but can cause significant morbidity in addition to dependency. The aim of the study was to determine the incidence of persistent opioid use after lung surgery. Methods. Patients who underwent lung resection from 2008 to 2013 for non-small cell lung cancer were identified in the Surveillance, Epidemiology and End Results-Medicare database. Patients were categorized as being chronic, intermittent, or naive preoperative opioid users using information obtained from part D records. Persistent opioid use was defined as having a filled opioid prescription between 3 and 6 months after lung resection. Results. A total of 6948 patients were identified, among whom 3946 (56.8%) were opioid naive, 2017 (29.0%) were intermittent opioid users, and 985 (14.2%) were chronic opioid users preoperatively. Persistent opioid use (3-6 months) after lung resection was high (31%), even among opioid-naive patients (17%). Among those who were previously opioid naive, independent predictors of persistent opioid use were receipt of adjuvant radiation or chemotherapy, less than 70 years of age, Charlson comorbidity score of 1 or 2, and residence in zip codes associated with lower education. Conversely, patients who underwent minimally invasive surgery were less likely to have persistent opioid use. Those with persistent opioid use after surgery did not show any trend toward returning to preoperative opioid utilization for at least the first postoperative year. Conclusions. Opioid dependence after lung resection in the population over 65 years of age is high but was significantly lower among those who received minimally invasive surgery, in addition to other factors.
