Massachusetts-based Atrius Health shakes up top jobs

Atrius Health, a Massachusetts-based alliance of five non-profit community-based physician groups, has gotten rid of or rearranged many of its top managers and eliminated several key positions after the resignation of its chief executive. The housecleaning reflects continued difficulties between Harvard Vanguard Medical Associates, Atrius' largest physicians group, and the four smaller groups that were lumped together under the Atrius banner.
