对终末期肾病患者结局的评价是治疗方案比较的重要组成部分。管理数据库中的相关数据有助于对终末期肾病死亡率进行比较。标准化死亡率已被肾脏病界广泛用于此类评估。精确的方法来评估调整后的死亡率与标准化死亡率比显示,即使有几个预期的死亡。显示了置信区间和概率值计算。即使计算准确,也会出现识别死亡率升高的分类错误。选择调整因子的标准进行审查。只有那些导致不可避免的死亡率变化的因素才应该被调整。使用美国肾脏数据系统死亡率表进行标准化死亡率计算的分析师必须使用与美国肾脏数据系统相同的方法计算死亡率和患者随访。特别是,患者随访必须包括退出后和转移后数据,但不包括终末期肾病前90天的数据。方法比较区域规范。
Evaluation of patient outcome for end-stage renal disease patients is an important component of the comparison of treatment protocols. End-stage renal disease mortality comparisons are facilitated by availability of the relevant data in administrative databases. The standardized mortality ratio has been widely used by the renal community for such evaluation. Accurate methods for evaluating adjusted mortality with the standardized mortality ratio are shown, even when there are few deaths expected. Both confidence interval and probability value calculations are shown. Classification errors for the identification of elevated mortality will occur even with accurate calculations. Criteria for choosing adjustment factors are reviewed. Only those factors that result in unavoidable variation in mortality should be adjusted for. Analysts using the US Renal Data System death rate tables for standardized mortality ratio computations must calculate mortality and patient follow-up with the same methods used by the US Renal Data System. In particular, patient follow-up must include postwithdrawal and posttransfer data but not data for the first 90 days of end-stage renal disease. Methods for comparison to a regional norm are presented.
