Several thousand physicians in Washington state, Minnesota, Florida and New York will participate in a 31/2-year project to determine what procedures physicians perform and how often.
The study is being funded with a $1.3 million grant from the Robert Wood Johnson Foundation to the Center for Research in Ambulatory Health Care Administration, the research arm of the Medical Group Management Association.
Project director Jeanine Barlow said the goal is to create the first objective database on physician utilization.
"Demand for this sort of information comes from all sides-consumers, policymakers, administrators and physicians," she said.
The demonstration states were selected on patient population, location, payer environment and state initiatives to advance data collection and sharing among providers.
The project will measure how utilization varies by setting, payer mix, group size and state.
