摘要
本文阐述了人群影响指标(PIMs)的定义和应用。PIMs借鉴了需要治疗人数(NNT)的概念,将临床指标扩展到人群,衡量某一个干预措施实施后在人群中的效果或某一危险因素对于人群的危害,为卫生政策的制定提供循证证据。衡量干预措施有效性的人群影响指标有:疾病影响人数、人群影响人数和人群预防人数。衡量危险因素有害性的人群影响指标有:暴露影响人数、暴露病例影响人数、人群影响人数、病例影响人数和消除风险t年后的人群影响人数。
This paper is aimed to introduce the definition and application of Population Impact Measures(PIMs).The PIMs use Number Need to Treat(NNT) for reference and generalize the variables of clinical research to interest population,which then can be used to measure the effectiveness of interventions and the harmfulness of risk factors,so as to provide evidence for making public health policy.Of the PIMs,the variables used for measuring the effectiveness of interventions include Disease Impact Number(DIN),Population Impact Number(PIN) and Number of Events Prevented in your Population(NEPP);The variables used for measuring the harmfulness of risk factors include Exposure Impact Number(EIN),Exposed Cases Impact Number(ECIN),Population Impact Number(PIN),Case Impact Number(CIN) and Population Impact Number of Eliminating a Risk factor(PIN-ER-t).
