The supply and use of selected medical technologies.

Over the years, both government and the private sector have used a mix of regulatory controls and competitive market incentives to reduce the rate of spending and minimize excess capacity in health services. Despite these efforts, this study finds an oversupply of five medical technologies in Pennsylvania, which adds costs and raises concern over the quality of care provided by underused facilities. Moreover, as providers compete for network selection, many continue to expand their service capabilities. These findings emphasize the importance of ongoing assessment of the appropriate application, supply, and use of medical services.
