Differences between physician social networks for cardiac surgery serving communities with high versus low proportions of black residents.
The researchers examined physician social networks, where individual physicians are tied together by a series of shared patients. They mapped these networks using medical claims data from the Medicare program and found substantial differences between physician social networks formed around CABG procedures serving health services areas with high and low proportions of black residents. Their conclusion was that physicians serving these communities are more isolated.
