Continuum Health Alliance, a privately-health Marlton physician services company, has acquired a controlling stake in Partners in Care, an East Brunswick, N.J., an independent provider network and management company, Continuum said Monday.

The deal, the price of which was not disclosed, will add a network of 600 doctors  to the 2,000 Continuum already serves, Continuum's chief executive Don McDaniel said.

Partners in Care, which was owned by doctors, helps with the move "from volume-based incentives to outcomes-based incentives," McDaniel said.  He said Continuum already does some of that, but wants to do more.

Partners in Care also helps Continuum expand its presence in Central New Jersey, McDaniel said.
