Case study. Several systems revisited

HSL takes a second look at four systems we profiled in 1994. In the fierce Chicago market, Lutheran General Health System expanded geographically by merging with a long-time ally. Similarly, New England's Hitchcock and Lahey clinics joined to become a regional powerhouse. Finally, Houston's Memorial Health System forged an alliance with the Sisters of Charity to build a network throughout southeast Texas. Read what each has accomplished and learned.
