Forty-seven percent of people who entered outpatient addiction treatment following a hospitalization for opioid overdose and successfully engaged with care remained in care for at least six months. Among people who did not successfully engage in care, about 2.9% remained in treatment for at least six months. The odds of remaining in treatment for six months were 32% higher for women. Across age groups, adults ages 50 to 64 were twice as likely to remain in treatment compared to those under age 30.
