Mortality in Treatment-seeking Older Adults Receiving Medications for Opioid Use Disorder.

Abstract

Older adults (OAs; age 55+ years) are increasingly seeking specialty treatment of opioid use disorder. Previous analyses of the Treatment Episode Data Set-Discharges (TEDS-D) database have reported higher rates of in-treatment mortality for those receiving medications for opioid use disorder (MOUD). We evaluate current trends in mortality for treatment-seeking OAs. Using the 2020 TEDS-D, logistic regression predicted in-treatment mortality for OAs from planned MOUD, service level, and interaction terms. Of the 26,993 OA treatment discharges, 679 people were discharged due to death (2.52%). OAs with MOUD (3.65%, 95% confidence interval [CI], 3.37%-3.95%) were significantly more likely to discharge due to death than those without MOUD (0.82%; 95% CI, 0.66%-1.01%). Most records were for nonintensive outpatient (83.7%; n = 22,588), which had the highest mortality (2.89%; 95% CI, 2.68%-3.11%); intensive services (n = 4405) had a mortality rate of 0.61% (95% CI, 0.42%-0.89%). Among OAs, planned MOUD with nonintensive outpatient services had a mortality rate of 4.17% (95% CI, 3.56%-4.9%). This TEDS-D analysis extends previous literature highlighting a significant interaction between planned MOUD and service intensity on in-treatment mortality for OAs. Additional research is needed to address the causal mechanisms behind these interactions and inform the delivery of safe effective care in the growing OA population.
