ObjectivesTo investigate the admission characteristics and hospital outcomes for Indigenous and non-Indigenous patients admitted to intensive units (ICUs) after major trauma.Design, SettingRetrospective analysis of Australian and New Zealand Intensive Care Society (ANZICS) Adult Patient Database data from 92 Australian ICUs for the 6-year period, 2010-2015.ParticipantsPatients older than 17 years of age admitted to public hospital ICUs with a primary diagnosis of trauma.Main Outcome MeasuresICU and overall hospital lengths of stay, hospital discharge destination, and ICU and overall hospital mortality rates for Indigenous and non-Indigenous patients.Results23 804 people were admitted to Australian public hospital ICUs after major trauma; 1754 (7.4%) were Indigenous Australians. The population-standardised incidence of admissions was consistently higher for Indigenous Australians than for non-Indigenous Australians (847 per million v 251 per million population; incidence ratio, 3.37; 95% CI, 3.19-3.57). Overall hospital mortality rates were similar for Indigenous and non-Indigenous patients (adjusted odds ratio [aOR], 1.04; 95% CI, 0.82-1.31). Indigenous patients were more likely than non-Indigenous patients to be discharged to another hospital (non-Indigenous v Indigenous: aOR, 0.84; 95% CI, 0.72-0.96) less likely to be discharged home (non-Indigenous v Indigenous: aOR, 1.17; 95% CI, 1.04-1.31).ConclusionThe population rate of trauma-related ICU admissions was substantially higher for Indigenous than non-Indigenous patients, but hospital mortality rates after ICU admission were similar. Indigenous patients were more likely to be discharged to a another hospital and less likely to be discharged home than non-Indigenous patients.© 2019 AMPCo Pty Ltd.
