(a) The Office of Road Safety uses police reported data relating to 'serious crashes' (i.e. a road crash that resulted in a fatality or hospitalisation), obtained from the Main Roads WA Integrated Road Information System (IRIS). Data from the IRIS system are based on complete, verified data for all crashes received from WA Police as recorded on P72 forms.
Police also maintain a Traffic Enforcement and Crash Executive Information System (TEACEIS) which is based on data recorded on the Fatal and Serious (1-18) Details form for fatal and serious injury crashes only. A serious injury crash for this purpose is determined by the attending officer and is not based on specific hospitalisation criteria - this determination may be amended and updated by a range of officers including the Investigating Officer, Major Crash Section and/or the Coroner. Data contained in TEACEIS are based on that collected by an attending Officer at their initial investigation, not following completion of further inquiries into the traffic crash as is the case for data contained in P72 forms.
(b) Serious crash data from the Main Roads IRIS system are complete and verified and have been received once thorough police investigations regarding the crash have been conducted. These crashes include those where a fatality or hospitalisation resulted.
Data from the TEACEIS system include only those determined as a fatal or serious injury crash by an attending officer and are based on initial investigations only.
(c) Hospital separation data is available from the Health Department of WA(tabulated below) . Injuries have been categorised according to the admitted Primary Diagnosis Code (using ICD-10-AM codes) which is assessed on the patient's discharge from hospital. Caution must be exercised when comparing the hospital separations with the Main Roads IRIS crash data as a person may have more than one hospital episode associated with a traffic accident. June 2007 was selected as the reporting period as it is the most up to date period for which clean, coded data are available.
