Prevalence of lifetime nonmedical opioid use among U.S. Health Center Patients aged 45 years and older with psychiatric disorders.

Given the prevalence, health center professionals should monitor, prevent, and treat new or reoccurring signs and symptoms of nonmedical opioid use in this high-risk group of aging patients with psychiatric disorders.
