目标：估计全国人工流产率在澳大利亚从1985年至2003年，使用医疗保险索赔的私人patients和医院发病率的公共patients.Design和setting统计数据：估计是基于澳大利亚和南澳大利亚州的数据收集有关堕胎。SA医院的发病率统计数据进行了比较，SA法定通知堕胎，以估计这些收集的准确性。然后，将南澳私人患者进行堕胎手术的医疗保险统计数据与私人患者的医院发病率统计数据进行比较。对来自医疗保险和医院发病率统计的全国堕胎统计数据进行了调整，以消除这些来源中的不准确之处。主要结果测量：1985年至2003年澳大利亚每年的人工流产数量;每1000名15-44岁妇女的堕胎率。1988年至2000年期间，基于私人病人医疗保险索赔的堕胎数量比南澳法定通知的堕胎数量高估了18.7%。89至1999年。使用与药物流产相关的主要诊断代码的医院发病率数据高估了法定通知2.3%（主要是因为再入院）。根据这些高估和估计的14.1%没有提交医疗保险索赔的私人患者（基于对新南威尔士州和维多利亚州私人诊所患者的调查），对国家统计数据进行了调整。据估计，澳大利亚的堕胎率从1985年的每1000名15-44岁妇女17.9例上升到1995年的21.9/1000的峰值，然后下降到2003年的19.7/1000（估计堕胎人数为84 460）。对收集国家统计数据提出了建议。
Aim: To estimate national rates of induced abortion in Australia from 1985 to 2003, using Medicare claim statistics for private patients and hospital morbidity statistics for public patients.Design and setting: Estimates were based on Australian and South Australian data collections relating to abortions. SA hospital morbidity statistics were compared with SA statutory notifications of abortions to estimate the accuracy of these collections. Medicare statistics on abortion procedures performed on private patients in South Australia were then compared with hospital morbidity statistics for private patients. National statistics on abortion derived from Medicare and hospital morbidity statistics were adjusted for inaccuracies found in these sources.Main outcome measures: Numbers of induced abortions in Australia for each year from 1985 to 2003; abortion rates per 1000 women aged 15-44 years.Results: Abortion numbers based on Medicare claims by private patients overestimated by 18.7% the number of abortions derived from statutory notifications in South Australia during the period 1988-89 to 1999-00. Hospital morbidity data using principal diagnosis codes relating to medical abortion overestimated statutory notifications by 2.3% (mainly because of readmissions). National statistics were adjusted for these overestimations and for the estimated 14.1% of private patients who would not have submitted Medicare claims (based on surveys of private-clinic patients in New South Wales and Victoria). The estimated Australian abortion rate increased from 17.9 per 1000 women aged 15-44 in 1985 to a peak of 21.9/1000 in 1995, then declined to 19.7/1000 in 2003 (estimated number of abortions, 84 460).Conclusion: There are no data currently available for deriving accurate numbers of induced abortions in Australia. Suggestions are made for collection of national statistics.
