三、应用高危评分法鉴别高危儿童具有一种或几种危险因素的小儿即是处于危险状态的高危儿童。如何鉴别高危儿童所具有的危险性大小,可用高危评分法对危险因素进行评分排列而筛选。 (一)相对危险度(RR) 它表示具有某种危险因素的人群发生不良结局的危险是不具有该种危险因素的人群发生不良结局的危险的倍数。即:RR=(具有某危险因素的儿童死亡数)/(无该危险因素的儿童死亡数)
Third, the application of high-risk scoring method to identify high-risk children with one or several risk factors in children is in danger of high-risk children. How to identify the risk of high-risk children with the size of high-risk scoring method can be used to rank the risk factors screened. (A) Relative risk (RR) It indicates that the risk of adverse outcomes in a population with a particular risk factor is a multiple of the risk of a poor outcome in a population without that risk factor. Namely: RR = (number of child deaths with certain risk factors) / (number of child deaths without this risk factor)
