Benchmarking and quality in residential and nursing homes: lessons from the US

Background Performance measurement and benchmarking are common concerns in the delivery of long term care. It is common to measure the performance of providers and to publicly report these data. This paper examines selected technical challenges facing those who design, implement and disseminate health care quality performance measures. Method Review of the application of measures of performance in the US nursing home sector. Results Using examples drawn from the skilled nursing home arena, problems ranging from data reliability and validity, the multi-dimensional nature of quality measures and selection bias as well as differential measurement abilities are discussed. Conclusions Benchmarking of performance is an inherently complex issue. However, to ensure that such comparisons are both fair and valid requires measures to be more technically sophisticated and sensitive to real changes attributable to changes in care.
