Participation in the measurement of population health and health care outcomes has become an explicit professional duty for doctors, but comparisons are difficult to make because outcomes are conceptually complex and largely qualitative. Observational data, particularly from routine hospital statistics, are useful complements to experimental data provided that their variable quality is taken into account and adjustments are made to minimize bias and confounding and to allow for the effects of differences in casemix, which are problematic because of the nature of severity.
参与人群健康和医疗保健结果的测量已成为医生明确的职业职责，但由于结果在概念上复杂且大多为定性的，因此难以进行比较。观察性数据，尤其是来自常规医院统计的数据，是实验数据的有用补充，前提是要考虑到其质量的多变性，并进行调整以尽量减少偏差和混杂因素，并考虑病例组合差异的影响，而病例组合差异由于严重程度的性质而存在问题。
