TECHNICAL NOTE 1 PERINATAL DEATHS PROCESS IMPROVEMENT
4 When coronial investigations are complete, causes of death information is passed to the Registrar of Births, Deaths and Marriages, as well as to the National Coroners Information System (NCIS). The ABS uses the NCIS as the only source of data to code coroner certified deaths. Where a case remains open on the NCIS at the time the ABS ceases processing and insufficient information is available to code a cause of death (e.g. a coroner certified death was yet to be finalised by the coroner), less specific ICD codes are assigned as required by the ICD coding rules.
5 The specificity with which open cases are able to be allocated an ICD-10 code is directly related to the amount and type of information available on the NCIS. The amount of information available for open cases varies considerably from no information to detailed police, autopsy and toxicology reports.
6 For 2008, increased resources and time were spent investigating coroners reports to identify specific causes of death. This involved making increased use of police reports, toxicology reports, autopsy reports and coroners findings for both open and closed cases to minimise the use of non-specific causes and intents. This has resulted in improved data quality enabling more specificity in assigning cause codes to coroner certified deaths.
7 In 2008, there were 63 (58%) perinatal cases with an open or not stated case status on NCIS which may not have had information available at the time of processing. However, all open cases were subject to the new process improvement and use was made of any available police reports, toxicology reports, autopsy reports or coroners findings. On a jurisdictional level, the proportion of cases which have a status of open on the NCIS varies. This means that the impact of the new process improvement has varied across states and territories.
8 For 2007 revised data, there were 35 (44%) perinatal cases with a status of 'open' or 'other' on NCIS which have not yet been subject to the process improvement. These cases will go through this process as part of the next revisions process. See Technical Note 2: Revisions Process for further information.
9 Further information on the impact of process improvements to 2008 causes of death data can be found in Technical Note 1: 2008 COD Collection - Process Improvements in Causes of Death, Australia, 2008 (3303.0).
