This analysis produced county-level estimates of opioid use disorder (OUD) and treatment needs in California counties. We estimated the demand for treatment in each county based on several data sources, assuming 20 percent of people with OUD seek opioid agonist treatment (i.e. buprenorphine or methadone). We estimated the county’s opioid agonist treatment capacity based on the Drug Enforcement Administration (DEA) and state data, and opioid treatment program data from Substance Abuse and Mental Health Services Administration (SAMHSA). Using a range of estimates of patients per waivered buprenorphine provider, we estimated the number of additional buprenorphine prescribers needed per county to achieve capacity to fill the estimated treatment gap. We present strategies to meet demand for treatment, showing a range using lower and upper estimates of the treatment gap and the treatment capacity.
