Eligible individuals were 18 years or older and met the federal definition of homelessness.Main Outcomes and MeasuresThe primary outcome measures included lifetime and past–6-month illicit substance use and substance type (methamphetamine, nonprescription opioids, or cocaine). Lifetime and current substance use treatment, unmet treatment need, types of treatments received, nonfatal overdose (lifetime and current episode of homelessness), and current possession of naloxone were measured. Population prevalence estimates with 95% Wald CIs were calculated using survey replicate weights.ResultsOf 3865 individuals approached, 3042 (79%) participated and an additional 158 participants were recruited through respondent-driven sampling. Among 3200 participants, the mean age was 46.1 (95% CI, 45.3-46.9) years, 67.3% (95% CI, 65.2%-69.3%) were cisgender male, and there were similar proportions of Black and African American, Hispanic and Latine, and White participants. Overall, an estimated 65.3% (95% CI, 62.2%-68.4%) of participants used illicit drugs regularly (≥3 times per week) in their lifetime; 41.6% (95% CI, 39.4%-43.8%) began using regularly before their first episode of homelessness and 23.2% (95% CI, 20.5%-25.9%) began using regularly after. In the past 6 months, an estimated 37.1% (95% CI, 32.9%-41.3%) of participants reported regular use of any drug; 33.1% (95% CI, 29.4%-36.7%) reported use of methamphetamines, 10.4% (95% CI, 7.9%-12.9%) reported use of opioids, and 3.2% (95% CI, 1.8%-4.6%) reported use of cocaine. In their lifetime, an estimated 25.6% (95% CI, 22.8%-28.3%) injected drugs and 11.8% (95% CI, 9.8%-13.8%) injected drugs in the past 6 months. Among those with any regular lifetime use, an estimated 6.7% (95% CI, 3.8%-9.5%) of participants were currently receiving treatment. Of those with any regular use in the last 6 months, an estimated 21.2% (95% CI, 17.9%-24.5%) reported currently wanting but not receiving treatment. An estimated 19.6% (95% CI, 17.4%-21.8%) of participants had a nonfatal overdose in their lifetime and 24.9% (95% CI, 21.3%-28.5%) currently possessed naloxone.Conclusion and RelevanceIn a representative study of adults experiencing homelessness in California, there was a high proportion of current drug use, history of overdose, and unmet need for treatment.

Samuels","doi":"10.1001/jama.2024.27976","DOIUrl":"https://doi.org/10.1001/jama.2024.27976","url":null,"abstract":"ImportanceRates of opioid use disorder (OUD) and associated mortality in the US remain high. Treatment of OUD with buprenorphine reduces morbidity and mortality. There have been national efforts to expand buprenorphine initiation to the emergency department (ED), where many patients with low treatment access seek medical care. Adoption and trends of emergency clinician buprenorphine prescribing are unknown.ObjectiveTo describe emergency clinician buprenorphine initiation for OUD, subsequent prescriptions, and changes over time in California.Design, Setting, and ParticipantsObservational retrospective study of buprenorphine prescriptions in the California Controlled Substance Utilization Review and Evaluation System (CURES) database from January 1, 2017, to December 31, 2022. Any patient aged 18 to 79 years with a California zip code who filled a buprenorphine prescription in CURES and their California prescribers were eligible for inclusion.ExposureBuprenorphine prescription by an emergency clinician.Main Outcomes and MeasuresOutcomes included (1) the number of patients prescribed buprenorphine; (2) the number of clinicians prescribing buprenorphine; (3) the number and characteristics of buprenorphine prescriptions; (4) the percentage of emergency clinician buprenorphine initiation prescriptions with subsequent linkage to a second prescription and continuous prescriptions, also reported as a continuation ratio; and (5) days and number of initiation prescriptions prior to continuous prescriptions.ResultsIn this retrospective observational study, 345 024 patients received 3.8 million buprenorphine prescriptions from 21 099 clinicians in California from 2017 to 2022. The mean age of patients at the time of first buprenorphine prescription was 37 years; 8187 (67%) were male.

The continuation ratio for patients to receive a second prescription within 40 days of an ED initiation was 2.8 (10 823/3916). The continuation ratio for patients to start 180 days or more of continuous prescriptions within 40 days of ED buprenorphine initiation was 18.3 (10 823/593) and 9.1 within 1 year (5989/655 [2017-2021 data]).Conclusions and RelevanceThese findings suggest increasing prescription of buprenorphine for OUD by California emergency clinicians from 2017 to 2022, with approximately 1 in 9 patients going on to receive continuous buprenorphine prescriptions within 1 year.","PeriodicalId":518009,"journal":{"name":"JAMA","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143444014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
