Further understanding of health care utilization\nis needed to inform prevention strategies for individuals who overdose from\nillegal drugs.<\/p>\n       <\/sec>\n       <sec>\n         <title>Methods<\/title>\n         <p>The Provincial Overdose Cohort includes linked administrative data on health\ncare utilization by individuals who experienced an illegal drug overdose event in BC\nbetween 1 January 2015 and 30 November 2016. Overdose cases were identified using\ndata from ambulance services, coroners\u2019 investigations, poison control centre calls and\nhospital, emergency department and physician administrative records. In total, 10 455\noverdose cases were identified and compared with 52 275 controls matched on age, sex\nand area of residence for a descriptive analysis of health care utilization.<\/p>\n       <\/sec>\n       <sec>\n         <title>Results<\/title>\n         <p>Two-thirds (66%) of overdose cases were male and about half (49%) were\n20\u201339 years old. Over half of the cases (54%) visited the emergency department and\nabout one-quarter (26%) were admitted to hospital in the year before the overdose\nevent, compared with 17% and 9% of controls, respectively. Nevertheless, nearly onefifth\n(19%) of cases were recorded leaving the emergency department without being\nseen or against medical advice. High proportions of both cases (75%) and controls\n(72%) visited community-based physicians. Substance use and mental health\u2013related\nconcerns were the most common diagnoses among people who went on to overdose.<\/p>\n       <\/sec>\n\t   <sec>\n         <title>Conclusion<\/title>\n         <p>People who overdosed frequently accessed the health care system in the\nyear before the overdose event. In light of the high rates of health care use, there may\nbe opportunities to identify at-risk individuals before they overdose and connect them\nwith targeted programs and evidence-based interventions. Further work using the BC\nProvincial Overdose Cohort will focus on identifying risk factors for overdose events\nand death by overdose.<\/p>\n       <\/sec>","DOI":"10.24095\/hpcdp.38.9.04","type":"journal-article","created":{"date-parts":[[2018,9,11]],"date-time":"2018-09-11T19:52:51Z","timestamp":1536695571000},"page":"328-338","source":"Crossref","is-referenced-by-count":28,"title":["Patterns of health care utilization among people who overdosed from illegal drugs: a descriptive analysis using the BC Provincial Overdose Cohort"],"prefix":"10.24095","volume":"38","author":[{"given":"Michael C.","family":"Otterstatter","sequence":"first","affiliation":[{"name":"BC Centre for Disease Control, Vancouver, British Columbia, Canada"},{"name":"School of Population and Public Health, University of British Columbia, Vancouver, British Columbia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexis","family":"Crabtree","sequence":"additional","affiliation":[{"name":"BC Centre for Disease Control, Vancouver, British Columbia, Canada"},{"name":"School of Population and Public Health, University of British Columbia, Vancouver, British Columbia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabina","family":"Dobrer","sequence":"additional","affiliation":[{"name":"BC Centre for Disease Control, Vancouver, British Columbia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brooke","family":"Kinniburgh","sequence":"additional","affiliation":[{"name":"Fraser Health Authority, Surrey, British Columbia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salman","family":"Klar","sequence":"additional","affiliation":[{"name":"Fraser Health Authority, Surrey, British Columbia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"Leamon","sequence":"additional","affiliation":[{"name":"Island Health Authority, Victoria, British Columbia, Canada"},{"name":"BC Observatory for Population and Public Health, BC Centre for Disease Control, Vancouver, British Columbia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"May-Hadford","sequence":"additional","affiliation":[{"name":"First Nations Health Authority, Vancouver, British Columbia, Canada"},{"name":"Public Health Agency of Canada, Ottawa, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Mill","sequence":"additional","affiliation":[{"name":"BC Centre for Disease Control, Vancouver, British Columbia, Canada"},{"name":"Public Health Agency of Canada, Ottawa, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mina","family":"Park","sequence":"additional","affiliation":[{"name":"BC Centre for Disease Control, Vancouver, British Columbia, Canada"},{"name":"BC Observatory for Population and Public Health, BC Centre for Disease Control, Vancouver, British Columbia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew W.","family":"Tu","sequence":"additional","affiliation":[{"name":"BC Coroners Service, Burnaby, British Columbia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Zheng","sequence":"additional","affiliation":[{"name":"BC Emergency Health Services, Victoria, British Columbia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10188","container-title":["Health Promotion and Chronic Disease Prevention in Canada"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.canada.ca\/en\/public-health\/services\/reports-publications\/health-promotion-chronic-disease-prevention-canada-research-policy-practice\/vol-38-no-9-2018\/health-care-utilization-among-people-who-overdosed-from-illegal-drugs-analysis-using-bc-provincial-overdose-cohort.html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,9,11]],"date-time":"2018-09-11T19:52:56Z","timestamp":1536695576000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.canada.ca\/en\/public-health\/services\/reports-publications\/health-promotion-chronic-disease-prevention-canada-research-policy-practice\/vol-38-no-9-2018\/health-care-utilization-among-people-who-overdosed-from-illegal-drugs-analysis-using-bc-provincial-overdose-cohort.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9]]},"references-count":0,"journal-issue":{"issue":"9"},"URL":"https:\/\/doi.org\/10.24095\/hpcdp.38.9.04","archive":["Internet Archive"],"relation":{},"ISSN":["2368-738X"],"issn-type":[{"value":"2368-738X","type":"print"}],"subject":[],"published":{"date-parts":[[2018,9]]}}}
