Role of primary care in opioid prescribing for older head and neck cancer survivors

Abstract

AbstractBackgroundOlder head and neck cancer (HNC) survivors have concerning rates of potentially unsafe opioid prescribing. Identifying the specialties of opioid prescribers for HNC survivors is critical for targeting the settings for opioid safety interventions. This study hypothesized that oncology and surgery providers are primarily responsible for opioid prescriptions in the year after treatment but that primary care providers (PCPs) are increasingly involved in prescribing over time.MethodsUsing linked Surveillance, Epidemiology, and End Results–Medicare data, a retrospective analysis was conducted of adults aged >65 years diagnosed between 2014 and 2017 with stage I–III HNC and who had ≥6 months of treatment‐free follow‐up through 2019. Starting at treatment completion, opioid fills were assigned to a prescriber specialty: oncology, surgery, primary care, pain management, or other. Prescriber patterns were summarized for each year of follow‐up. Multinomial logistic regression models captured the likelihood of opioids being prescribed by each specialty.ResultsAmong 5135 HNC survivors, 2547 (50%) had ≥1 opioid fill (median, 2.1‐year follow‐up). PCPs prescribed 47% of all fills (42%–55% each year). PCPs prescribed opioids to 45% of survivors with ≥1 opioid fill, which was a greater share than other specialties. PCPs prescribed longer supplies of opioids (median, 20 days/fill; median, 30 days/year) than oncologists or surgeons. The likelihood of an opioid being prescribed by an oncology provider was four times lower than that of it being prescribed by a PCP.ConclusionsPCP involvement in opioid prescribing remains high throughout HNC survivorship. Interventions to improve the safety of opioid prescribing should target primary care, as is typical for opioid reduction efforts in the noncancer population.
