Nurse practitioners in primary care. VI. Assessment of their deployment with the Utilization and Financial Index

Abstract

The impact of multidisciplinary teams that incorporate nurse practitioners on total use of health services was measured with the new Utilization and Financial Index (UF-Index). The data from two studies, a randomized controlled trial and a before-and-after study, showed that, in spite of large increases in use of ambulatory services by practice populations served by family physician-nurse practitioner teams, the ultimate effect has been a substantial reduction in total use of health services. The effect was associated with major reductions in hospital care for the same populations. Such economic advantages to society proved feasible within a fee-for-service context and in settings where rigorous evidence demonstrated no concurrent deterioration in health status of patients or in quality of care.
