Mid Coast Hospital will purchase Parkview Adventist Medical Center as part of a "prepackaged bankruptcy plan" after Parkview filed for Chapter 11 bankruptcy relief Tuesday morning. Boards of both hospitals approved the sale of the 55-bed Parkview facility, which began diverting ambulances to other hospitals Tuesday morning. Throughout the week, as patients are discharged, Parkview will "wind down" its emergency department, intensive care unit and medical/surgical department departments, Parkview Chief Executive Officer Randee Reynolds said Tuesday. As part of its transition plan, Parkview will enter a contract with Bluewater Emergency Partners, which operates Mid Coast Hospital's emergency services. Bluewater will assume Parkview's emergency services contract with Central Maine Medical Center starting at 6 p.m. Tuesday.
