A revised approach to performance measurement for health-care estates.

The purpose of the research was to show how lean asset thinking can be applied to UK health-care facilities using different measures to compare the estates contribution to the business of health-care providers. The challenge to conventional wisdom matches that posed by 'Lean Production' to 'Mass Manufacturing'. Data envelope analysis examined the income generated and patient-occupied area as outputs from the gross area of a NHS Trust's estate. The approach yielded strategic comparisons that conventional facilities management measures of cost per square metre hide. The annual cost of an excess estate is conservatively estimated at pound 600,000,000 (in England alone). Further research to understand the causes of the excess is needed. Meanwhile the research illustrates the power of an alternative way of assessing facilities performance. The authors are not aware of the lean asset perspective previously being applied to health-care facilities. The research shows the underlying fallacy of relying on cost per square metre as the primary measure of asset performance. The results and discussion will be particularly useful to senior estates and facilities managers wishing to use new measures to define strategic estates targets.
