To describe the causes of death codes assigned in Australian Bureau of Statistics (ABS) mortality data to deaths in Australia from 2000 to 2005 that were coded as intentional self-harm (suicide) in the National Coroners Information System (NCIS).
Data for deaths in the period mid-2000 to end-2005 were obtained from the National Coroners Information System database (NCIS). We selected cases recorded in the NCIS as having intent at completion = intentional self-harm. The record linkage was done by the ABS and NCIS and did not form part of this project.
During the study period, 12,786 deaths recorded in NCIS were assigned intent at completion = intentional self-harm. Of these, 9,937 (77.7%) had been assigned ICD-10 underlying cause of death codes in the range normally reported as suicide (X 60-X 84), 1,135 had been assigned other ICD-10 codes and the remaining 1,714 (13.4%) NCIS records did not hold any ICD-10 codes.
These findings confirm that routine mortality data have underestimated suicide mortality in Australia in recent years probably due to incomplete coroner data being available to ABS coders. Certain types of unintentional injury deaths have been over-estimated. Incomplete linkage of NCIS and ABS data in the source data used for this project complicates calculations of adjusted estimates and trends.
描述澳大利亚统计局（ABS）死亡率数据中为2000年至2005年澳大利亚死亡病例所分配的死因编码，这些死亡病例在国家死因裁判信息系统（NCIS）中被编码为故意自伤（自杀）。
2000年年中至2005年年末期间的死亡数据来自国家死因裁判信息系统数据库（NCIS）。我们选择了NCIS中记录为完成时意图 = 故意自伤的病例。记录链接由ABS和NCIS完成，并非本项目的一部分。
在研究期间，NCIS记录的12,786例死亡被确定为完成时意图 = 故意自伤。其中，9,937例（77.7%）被分配了国际疾病分类第十版（ICD - 10）通常报告为自杀的根本死因编码范围（X60 - X84），1,135例被分配了其他ICD - 10编码，其余1,714例（13.4%）的NCIS记录没有任何ICD - 10编码。
这些发现证实，近年来澳大利亚的常规死亡率数据可能低估了自杀死亡率，这可能是由于ABS编码人员可获得的死因裁判数据不完整所致。某些类型的意外伤害死亡被高估了。本项目所使用的源数据中NCIS和ABS数据的不完全链接使调整后的估计值和趋势的计算变得复杂。
