工作背景：收集的数据集经常用于人口为基础的research.Aim：本研究的目的是评估医院出院数据的准确性，在确定产科出血诊断和程序，并估计其人口incidence.Methods：随机选择的1200名妇女的医疗记录进行了审查，并与产科出血诊断和程序在医院出院的数据进行比较。敏感性，特异性，阳性和阴性预测值计算使用的医疗记录作为“金标准”。估计人口发病率进行计算和加权抽样probability.Results：估计人口发病率为任何产前出血为1.8每100，产后出血为7.2每100名妇女。产科出血诊断和手术代码往往被低估，敏感性范围为28.3%至100%。所有代码的特异性均为98.9%或更高。产科出血的识别不同水平的severity.Conclusion：结果表明，人口健康数据集可以是一个可靠的信息来源，但是，这些数据集可以得到改善，更完整的文档中的医疗记录。
Background: Routinely collected datasets are frequently used for population-based research but their accuracy needs to be assured.Aim: This study aims to assess the accuracy of hospital discharge data in identifying obstetric haemorrhage diagnoses and procedures, and estimate their population incidence.Methods: The medical records of 1200 randomly selected women were reviewed and compared with obstetric haemorrhage diagnoses and procedures in the hospital discharge data. Sensitivity, specificity, and positive and negative predictive values were calculated using the medical records as the 'gold standard'. Estimates of population incidence were calculated and weighted by the sampling probabilities.Results: Estimated population incidence for any antepartum haemorrhage was 1.8 per 100, and post partum haemorrhage was 7.2 per 100 women. Obstetric haemorrhage diagnosis and procedure codes tended to be underreported, with sensitivities ranging from 28.3% to 100%. All codes had specificities of 98.9% or greater. The identification of obstetric haemorrhage differed between levels of severity.Conclusion: The results indicate that population health datasets can be a reliable information source; however, these datasets could be improved with more complete documentation in medical records.
