如何评价慢性病病例发现：不同指标的比较
How to assess case-finding in chronic diseases: Comparison of different indices
摘要：
最近，我们提出了一个新的疾病-死亡模型，其中包括一个未确诊的慢性疾病的状态之前，已确诊的疾病。根据这一模式，出现了一个问题，即在所有这些州都存在死亡率的情况下，如何评估病例发现。我们模拟了两种不同的情况下的病例发现的性能，并应用几个指标来评估在这两种情况下的病例发现。基于流行率的指数之一导致错误的结论。部分指标对区分病例发现质量不敏感。基于发病率的指数表现良好。如果可能，应首选基于发病率的指数。
英文摘要：
Recently, we have proposed a new illness-death model that comprises a state of undiagnosed chronic disease preceding the diagnosed disease. Based on this model, the question arises how case-finding can be assessed in the presence of mortality from all these states. We simulate two scenarios of different performance of case-finding and apply several indices to assess case-finding in both scenarios. One of the prevalence based indices leads to wrong conclusions. Some indices are partly insensitive to distinguish the quality of case-finding. The incidence based indices perform well. If possible, incidence based indices should be preferred.
