Where in the world are the ambulatory benchmarking data?

If you haven't already been forced to take a hard look at your ambulatory care, increasing payer and patient pressures mean you'll have to soon. Ambulatory care accounts for more than half of U.S. health expenditures and could account for half of average hospital revenue by the year 2000. The most difficult data to find is on physician offices but several proprietary databases offer that information, and a new project from the Accreditation Association for Ambulatory Health Care will focus on collecting it. Some free data are available from state and federal sources, but are not very current, not adjusted in any way, and may take you a while to receive.
