(P2-18) ICU Surge Capacity in Australian Major Trauma Centres

Abstract

IntroductionMass casualty incidents (MCIs), requiring Trauma critical care, are increasingly likely. The ability to scale operations up i.e. ‘surge capacity’, is vital for ensuring scarce resources are used efficiently. The number of intensive care unit (ICU) beds is one of the key resources and indicators of a hospital's capacity and thus a vital area to target when assessing a systems ability to surge its Trauma ICU capabilities.ObjectiveThe study attempted to assess whether ICU facilities at major hospitals in large Australian cities would be able to respond to an event on the magnitude of the Madrid tragedy. This is the first report to measure Australia's major hospitals intensive care trauma surge capacity using Madrid as a standard.MethodsIn this prospective, cross-sectional analysis, we conducted a survey of major urban ICU trauma centres in the 8 state and Territory Capital cities of Australia. 14 Trauma Centre ICU's were targeted. The study was composed of two parts, A & B. Part A of the study consisted of an online survey, Part B, consisted of a follow-up telephone questionnaire. Full Ethics approval was sought and obtained.ResultsThere were 8 replies to the survey giving a 57% participation rate. At the time of this snap-shot survey the total number of Physically available ICU beds throughout the 8 Level I trauma centres was 52.5. All hospitals had at least 3 spare beds. This ranged from 3 to 10 beds. After accounting for the flux in beds post admissions & discharges there was a 21% increase in bed availability, which was further increased by a magnitude of 28% to an average of 10.125 beds, if all elective surgical procedures were cancelled. When using the Madrid ICU surge (29 new ICU patients) as a gold standard against which to compare, it was found the largest trauma ICU in Australia could have managed 62% of this surge. On average the 8 trauma centres would have handled only 34.75% of the Madrid ICU surge.ConclusionsIn the event of a major traumatic disaster on the scale of the Madrid atrocity, few if any of Australia's major trauma centres have the capacity to cope with the requisite surge. More research and novel ways of addressing this challenge are needed.
