Burden of Chronic and Heavy Opioid Use Among Elderly Community Dwellers in the U.S

Opioid overprescribing may fuel the opioid epidemic and increase the risk of complications of opioid misuse. This study examined trends and determinants of chronic and heavy opioid use among elderly community dwellers in the U.S.

Medicare Current Beneficiary Surveys data from 2006 to 2019 were used. Common opioid medications were identified in the prescription medication files (n=47,264). Patients with Chronic users were defined as those receiving 6 or more opioid prescriptions within a year or on medication for 3 or more months, and heavy users were those having an average daily dose of 90 or more morphine milligram equivalents or 3,780 morphine milligram equivalents or more per continuous treatment episode.

One in 6 elderly community dwellers ever used opioids during the study period. Chronic users were more likely to be women than men (68.9% vs 31.1%, p<0.001). Of all survey participants, 4.3% were chronic users, and 2.8% were heavy users. Among ever users, 27.7% were chronic users, and 18.1% were heavy users. The rate of opioid use rose from 12.1% in 2006, peaked at 22.8% in 2013, and decreased to 11.7% in 2019. Chronic use was 5.1%, 10.7%, and 7.6%, respectively. Heavy use was 5.5%, 10.7%, and 7.6%, respectively. However, for chronic and heavy users, there was no significant difference in the median opioid dosage and opioid duration between males and females.

Among elderly Medicare beneficiaries, opioid prescriptions have been decreasing since 2013. However, a substantial number of elderly people were chronic and heavy users, calling for better opioid management among them.
