Lynch A, et al. - The present study was performed to examine 10-year trends in opioid use disorder with heroin (OUD-H) among older persons and to compare those with typical-onset (age < 30 years) to those with late (age 30+) onset. Researchers conducted a naturalistic observation using the most recent (2008–2017) Treatment Episode Data Set-Admissions. Admission trends, demographics, substance use history were measured. Among older U.S. adults, late-onset heroin use is increasing. An additional study is required to understand the unique needs of this population better. This study’s findings indicated that as this population grows, geriatric psychiatrists may be increasingly called upon to provide specialized care to people with late-onset OUD-H.
