We evaluated 5 years of a hospital-wide SUD initiative which included an inpatient addiction consult team (ACT), low-threshold Bridge Clinic, recovery coaches, and office-based addiction treatment (OBAT) nurses. Naturalistic registry study. We calculated frequencies of patient contacts, types of substance use diagnoses, and medication treatment initiation and duration. From 2014 to 2019, 7,036 unique patients were seen, including 4,959 by ACT, 1,197 in Bridge Clinic, 2,250 by a recovery coach, and 979 by an OBAT nurse. The median age was 47, 31% were women, 80% were white, 7% were black, 6% were Hispanic/Latinx, and 25% were experiencing homelessness. Alcohol use disorder was seen in 62%, opioid use disorder in 54%, cocaine use disorder in 29%, benzodiazepine use disorder in 14%, and stimulant use disorder in 7%. Co-occurring medical and psychiatric illnesses were common; 35% had hepatitis C, 59% depression, 66% cation treatment episodes were longer with buprenorphine. People who use illicit drugs (PWUD) experience significant barriers to healthcare. However, little is known about levels of attachment to primary care (defined as having a regular family doctor or clinic they feel comfortable with) and its association with unmet healthcare needs in this population. In a Canadian setting that features novel publicly-funded interdisciplinary primary care clinics, we sought to examine the prevalence and correlates (including attachment to primary care) of unmet healthcare needs among PWUD. Data were derived from two prospective cohort studies of PWUD in Vancouver, Canada between December 2017 and November 2018. Multivariable logistic regression was used to identify factors associated with self-reported unmet healthcare needs among participants reporting any health issues. In total, 743 (83.6%) of 889 eligible participants r
