MEDICAL GROUPS: Top 10 largest in the U.S.

This is a study of large medical group practices, comparing characteristics of academic medical groups (“gown”) with those not linked to medical schools (“town”).  A large part of the study involved developing a list of the 100 largest practices – which included those from about 500 physicians at the bottom of the list of 100 to ten times that many at the top.  An average of about one-quarter of physicians in these large practices were primary care physicians (PCPs).  However, there was a smaller percentage of PCPs in the academic practices than in the community practices.
