Evaluating Age as a Predictor of Postoperative Opioid Use and Prescribing Habits in Older Adults With Cancer

Objective: To assess the narcotic use of older patients after oncologic resection. Design: Retrospective review. Setting and Participants: Adults with neoplasms undergoing resection at a tertiary academic medical center. Methods: Open and minimally invasive resections of the pancreas, bowel, rectum, lung, breast, and skin were included. Emergent procedures, chronic opioid users, and benign pathology were excluded. Narcotic use was measured using morphine equivalents (MEQs, milligrams of morphine) at multiple time points and compared between younger and older (aged >= 65 years) patients. Refill requests were within 30 days of index procedure. Results: A total of 445 patients were eligible, and 245 were >= 65 years old. Despite longer length of stay (3 vs 2 days, P=.01), older patients used less narcotic medication [39.8 (150) mg vs 84 (229) mg, P=.004], and reported lower pain scores [1.3 (3.3) vs 2.8 (4.5), P=.0001] over the course of their hospitalization. Additionally, older patients had lower normalized narcotic use [15.3 (150) mg vs 77.4 (240) mg, P=.0001] in the last 48 hours of their admission. Following discharge, older patients had a lower median discharge MEQ (DC MEQ) compared with younger patients, 75 (150) mg vs 112.5 (102.5) mg, P=.002. Further stratifying older patients into age cohorts (65-74 years, 75-84 years, >= 85 years) revealed progressively less narcotic use as measured by total inpatient MEQ and final 48 hours. Additionally, progressively older patients were discharged with progressively lower DC MEQ compared with younger patients, 90 (112.5) mg, 50 (131.3) mg, and 0 (60) mg vs 112.5 (102.5) mg, P<.0001, respectively. Finally, older patients requested refills less often than younger counterparts, 6.5% vs 14.5%, P=.006. Conclusions and Implications: Older patients with cancer reported lower pain scores, consumed less narcotics, were discharged with significantly less narcotics, and called for refills less often compared with younger patients after surgery. These data suggest this population may require less opioids for satisfactory pain control, and development of a guideline targeting postoperative multimodal analgesia in older adults is warranted.
