title: NHS resources: scales of variation.
abstract: 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.
