Noble Health Alliance, organized 2013 by Abington Health, Aria Health, Crozer-Keystone Health System and Einstein Healthcare Network, will disband in June, after three of the founding members entered into mergers or sales, the Fort Washington group said Tuesday.

Only Einstein has not struck a deal. Abington and Aria have or are scheduled to become part of a Jefferson, and Crozer is selling itself to Prospect Medical Holdings Inc.

Noble was founded to allow the systems, with 15 hospitals and 4,600 physicians when it started, to work cooperatively to improve quality and lower costs without having to surrender independence.

Certain of Noble's functions related to its physician network will continue through the end of the year, said Noble, which has a 10-member staff.
