Abstract
OBJECTIVE: Timely and appropriate assessment and management within the ED impacts patient outcomes including in-hospital mortality and length of stay (LOS). Within the ED, several processes facilitate timely recognition of the need for intensive care unit (ICU) admission. This study describes characteristics and outcomes for patient presentations admitted to ICU from ED, categorised by Australasian Triage Score (ATS), ICU admission time and ICU admission source. METHODS: A retrospective observational cohort study with linked health data of adult ICU admissions during 2012. Outcomes measured included: ED, ICU and hospital LOS, time to see ED clinician, ICU readmission and ICU and hospital mortality rates. RESULTS: In total, 423 ICU admissions occurred within 24 h of ED arrival; 395 were admitted directly to ICU; 28 were admitted to the ward before ICU admission. ATS 3/4/5 patients comprised 26.7% of ICU admissions and experienced longer waits to be seen, longer total ED LOS, shorter ICU LOS and a lower mortality rate than those triaged ATS 1/2. Compared to ICU admissions during business hours, admissions outside hours did not differ significantly for any outcome measured. Patients admitted to the ward before ICU experienced longer waits to be seen and longer ED LOS. CONCLUSION: Most patients are appropriately identified in ED as requiring ICU admission, although around one in four were triaged ATS 3/4. Patients admitted to the ward first tended to have poorer outcomes than those directly admitted to ICU. Factors predicting the need for ICU admission should be identified to support clinical decision-making.
