反映医疗效果的病死率与治愈率,是通常评价医疗质量的主要指标,有些医院将它作为考核工作、评发奖金的主要依据,但是究其指标本身,不论治愈率还是病死率,都是相对数的构成指标,只是由于医院统计这个特定条件,才把它当作频率指标来使用,正因为指标本身实际上是构成比,某一个医疗效果等级(治愈、好转、未愈、病死)人数有变动时,必然使其它等级的比例随之发生改变(虽然变化等级的本身人数并未发生改变),所以,评价其强度,也自然受到那些能够影响医疗效果等级值的各种因素的影响,最常见的因素是科别出院人数构成和住院病人疾病构成的影响。如某年某院出院病 The mortality rate and cure rate that reflect medical effects are the main indicators for evaluating the quality of medical care. Some hospitals use it as the main basis for assessment work and appraisal of bonuses. However, the indicators themselves, whether the cure rate or the mortality rate, are relative The composition index of the number is only used by the hospital as a frequency indicator because of the specific condition of the hospital statistics. Because the indicator itself is actually a constituent ratio, there is a certain number of medical effect levels (cure, improvement, recovery, death). When changes occur, it is inevitable that the proportion of other grades will change (although the number of changes in the scale itself does not change), so the evaluation of its strength is naturally influenced by various factors that can affect the value of the medical effect rating. The common factors are the composition of the number of discharges from hospitals and the impact of inpatient illnesses. If a hospital is discharged in a certain year
