Despite documented geographic differences in overdose mortality and substances implicated in overdose mortality trends, injection-involved overdose mortality has not been summarized at a subnational level.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>We aimed to estimate the annual number of injection-involved overdose deaths in each US state from 2000 to 2020.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a stratified analysis that used data from drug treatment admissions (Treatment Episodes Data Set\u2013Admissions; TEDS-A) and the National Vital Statistics System (NVSS) to estimate state-specific percentages of reported drug overdose deaths that were injection-involved from 2000 to 2020. TEDS-A collects data on the route of administration and the type of substance used upon treatment admission. We used these data to calculate the percentage of reported injections for each drug type by demographic group (race or ethnicity, sex, and age group), year, and state. Additionally, using NVSS mortality data, the annual number of overdose deaths involving selected drug types was identified by the following specific multiple-cause-of-death codes: heroin or synthetic opioids other than methadone (T40.1, T40.4), natural or semisynthetic opioids and methadone (T40.2, T40.3), cocaine (T40.5), psychostimulants with abuse potential (T43.6), sedatives (T42.3, T42.4), and others (T36-T59.0). We used the probabilities of injection with the annual number of overdose deaths, by year, primary substance, and demographic groups to estimate the number of overdose deaths that were injection-involved.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In 2020, there were 91,071 overdose deaths among adults recorded in the United States, and 93.1% (84,753\/91,071) occurred in the 46 jurisdictions that reported data to TEDS-A. Slightly less than half (38,253\/84,753, 45.1%; 95% CI 41.1%-49.8%) of those overdose deaths were estimated to be injection-involved, translating to 38,253 (95% CI 34,839-42,181) injection-involved overdose deaths in 2020. There was large variation among states in the estimated injection-involved overdose death rate (median 14.72, range 5.45-31.77 per 100,000 people). The national injection-involved overdose death rate increased by 323% (95% CI 255%-391%) from 2010 (3.78, 95% CI 3.33-4.31) to 2020 (15.97, 95% CI 14.55-17.61). States in which the estimated injection-involved overdose death rate increased faster than the national average were disproportionately concentrated in the Northeast region.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Although overdose mortality and injection-involved overdose mortality have increased dramatically across the country, these trends have been more pronounced in some regions. A better understanding of state-level trends in injection-involved mortality can inform the prioritization of public health strategies that aim to reduce overdose mortality and prevent downstream consequences of injection drug use.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/49527","type":"journal-article","created":{"date-parts":[[2024,4,5]],"date-time":"2024-04-05T10:30:30Z","timestamp":1712313030000},"page":"e49527","source":"Crossref","is-referenced-by-count":7,"title":["Estimated Number of Injection-Involved Overdose Deaths in US States From 2000 to 2020: Secondary Analysis of Surveillance Data"],"prefix":"10.2196","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0244-7458","authenticated-orcid":false,"given":"Eric William","family":"Hall","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7728-0587","authenticated-orcid":false,"given":"Patrick Sean","family":"Sullivan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7667-4197","authenticated-orcid":false,"given":"Heather","family":"Bradley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2024,4,5]]},"reference":[{"issue":"394","key":"ref1","first-page":"1","author":"Hedegaard, H","year":"2020","journal-title":"NCHS Data Brief"},{"issue":"457","key":"ref2","first-page":"1","author":"Spencer, MR","year":"2022","journal-title":"NCHS Data Brief"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s40122-018-0097-6"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm7050e3"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1126\/science.aau1184"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm7235a3"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm6817a3"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm7226a4"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.drugalcdep.2022.109428"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.drugalcdep.2013.05.014"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.2105\/ajph.91.1.42"},{"key":"ref12","year":"2018","journal-title":"Integrating Responses at the Intersection of Opioid Use Disorder and Infectious Disease Epidemics: Proceedings of a Workshop"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1038\/d41586-019-02019-3"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm7006a4"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1080\/10826084.2023.2287220"},{"issue":"440","key":"ref16","first-page":"1","author":"Spencer, MR","year":"2022","journal-title":"NCHS Data Brief"},{"key":"ref17","unstructured":"2020 Viral Hepatitis Surveillance Report-United StatesCenters for Disease Control and Prevention20222024-02-29https:\/\/www.cdc.gov\/hepatitis\/statistics\/2020surveillance\/index.htm"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1002\/hep.31756"},{"issue":"17","key":"ref19","first-page":"453","volume":"64","author":"Zibbell, JE","year":"2015","journal-title":"MMWR Morb Mortal Wkly Rep"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.2017.304132"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1007\/s11524-010-9495-8"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.f174"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1111\/add.13326"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1007\/s11524-023-00717-y"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1111\/add.14519"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/ciz321"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-017-4210-2"},{"key":"ref28","unstructured":"Treatment Episode Data Set: Admissions (TEDS-A)Substance Abuse and Mental Health Services Administration20222024-02-29https:\/\/www.datafiles.samhsa.gov\/dataset\/treatment-episode-data-set-admissions-2002-teds-2002-ds0001"},{"key":"ref29","unstructured":"Restricted-Use Vital Statistics DataNational Center for Health Statistics20222024-02-29https:\/\/www.cdc.gov\/nchs\/nvss\/nvss-restricted-data.htm"},{"key":"ref30","unstructured":"A guide to state implementation of ICD-10 for mortality.
