The dangers inherent in comparing measures of health service provision and usage at high levels of aggregation and of ignoring variations at lower levels are illustrated with particular reference to regional and subregional level in the NHS. Analysis of variance indicates that, for a wide range of variables, there is more variation at the subregional level than regional level.
在国民医疗服务体系(NHS)中,特别参照区域和次区域层面,说明了在高度汇总层面比较医疗服务提供和使用的衡量标准以及忽视较低层面差异所固有的风险。方差分析表明,对于广泛的变量,次区域层面的差异大于区域层面。
