The quarterly proportion of opioid\u2010related overdose deaths attributed to people experiencing homelessness increased from 7.2% (26\/359) in July\u2013September 2017 to 16.8% (97\/578) by April\u2013June 2021 (trend test <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01). Compared with housed decedents, those experiencing homelessness were younger (61.3 versus 53.1% aged 25\u201344), had higher prevalence of mental health or substance use disorders (77.1 versus 67.1%) and more often visited hospitals (32.1 versus 24.5%) and emergency departments (82.6 versus 68.5%) in the year prior to death. Fentanyl and its analogues more often directly contributed to death among people experiencing homelessness (94.0 versus 81.4%), as did stimulants (67.4 versus 51.6%); in contrast, methadone was less often present (7.8 versus 12.4%). Individuals experiencing homelessness were more often in the presence of a bystander during the acute toxicity event that led to death (55.8 versus 49.7%); and where another individual was present, more often had a resuscitation attempted (61.7 versus 55.1%) or naloxone administered (41.2 versus 28.9%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>People experiencing homelessness account for an increasing proportion of fatal opioid\u2010related overdoses in Ontario, Canada, reaching nearly one in six such deaths in 2021.<\/jats:p><\/jats:sec>","DOI":"10.1111\/add.16357","type":"journal-article","created":{"date-parts":[[2023,10,17]],"date-time":"2023-10-17T04:01:27Z","timestamp":1697515287000},"page":"334-344","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Opioid\u2010related overdose deaths among people experiencing homelessness, 2017 to 2021: A population\u2010based analysis using coroner and health administrative data from Ontario, Canada"],"prefix":"10.1111","volume":"119","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0300-9954","authenticated-orcid":false,"given":"Richard G.","family":"Booth","sequence":"first","affiliation":[{"name":"Arthur Labatt Family School of Nursing Western University  London Canada"},{"name":"ICES (formerly the Institute for Clinical Evaluative Sciences)  Ontario Canada"},{"name":"London Health Sciences Centre Lawson Health Research Institute  London Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salimah Z.","family":"Shariff","sequence":"additional","affiliation":[{"name":"Arthur Labatt Family School of Nursing Western University  London Canada"},{"name":"ICES (formerly the Institute for Clinical Evaluative Sciences)  Ontario Canada"},{"name":"London Health Sciences Centre Lawson Health Research Institute  London Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brooke","family":"Carter","sequence":"additional","affiliation":[{"name":"ICES (formerly the Institute for Clinical Evaluative Sciences)  Ontario Canada"},{"name":"London Health Sciences Centre Lawson Health Research Institute  London Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen W.","family":"Hwang","sequence":"additional","affiliation":[{"name":"ICES (formerly the Institute for Clinical Evaluative Sciences)  Ontario Canada"},{"name":"MAP Centre for Urban Health Solutions, Li Ka Shing Knowledge Institute Unity Health Toronto  Toronto Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aaron M.","family":"Orkin","sequence":"additional","affiliation":[{"name":"MAP Centre for Urban Health Solutions, Li Ka Shing Knowledge Institute Unity Health Toronto  Toronto Canada"},{"name":"Department of Family and Community Medicine University of Toronto  Toronto Canada"},{"name":"Dalla Lana School of Public Health University of Toronto  Toronto Canada"},{"name":"Department of Emergency Medicine St Joseph\u2019s Health Centre  Toronto Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheryl","family":"Forchuk","sequence":"additional","affiliation":[{"name":"Arthur Labatt Family School of Nursing Western University  London Canada"},{"name":"London Health Sciences Centre Lawson Health Research Institute  London Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1468-1965","authenticated-orcid":false,"given":"Tara","family":"Gomes","sequence":"additional","affiliation":[{"name":"ICES (formerly the Institute for Clinical Evaluative Sciences)  Ontario Canada"},{"name":"MAP Centre for Urban Health Solutions, Li Ka Shing Knowledge Institute Unity Health Toronto  Toronto Canada"},{"name":"Leslie Dan Faculty of Pharmacy University of Toronto  Toronto Canada"},{"name":"Institute of Health Policy, Management and Evaluation University of Toronto  Toronto Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,10,16]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.k3207"},{"key":"e_1_2_10_3_1","doi-asserted-by":"crossref","unstructured":"Government of Canada.Opioid\u2010 and stimulant\u2010related harms in Canada.
