Prescription Opioids Dispensed to Patients with Cancer with Bone Metastasis: 2011-2017.

Opioid therapy is a first-line approach for moderate-to-severe pain associated with cancer with bone metastasis (CBM). The decade-long decline in opioid prescribing in the U.S. would not be expected to affect patients with CBM. We investigated trends in opioids dispensed to patients with CBM using data from a large commercial claims database. From 2011Q2 to 2017Q4, the percentage of patients with CBM prescribed at least one day of opioids in a quarter declined from 28.1% to 24.5% (p<0.001) for privately insured patients aged 18-64, and, from 39.1% to 30.5% (p<0.001) for Medicare Advantage (MA) patients aged 65 or older. Among patients with at least one day of opioids in a quarter, the average morphine milligram equivalents dispensed declined by 37% and 11% (p<0.001 for both) for privately insured and MA patients, respectively. Our findings raise concerns about potential unintended consequences related to population-level reduction in opioid prescribing. © AlphaMed Press 2021.
