Perinatal mortality rates are an important index of the performance of perinatal health care services, but comparisons are confounded by variations in the prior risk status of the clienteles of different districts and different maternity units. A method of allowing for these differences has been devised. It is based jointly upon the exclusion of certain classes of birth, and on indirect standardisation for birthweight and a number of modifying factors. The method is described, tested, demonstrated, and proposed for more general use.
围产期死亡率是围产期医疗服务绩效的一项重要指标,但不同地区和不同产科单位的服务对象先前风险状况存在差异,这使得比较变得复杂。现已设计出一种考虑这些差异的方法。该方法基于排除某些类别的分娩情况,并对出生体重和一些修正因素进行间接标准化。本文对该方法进行了描述、测试、论证,并建议更广泛地使用。
