Hospital/healthcare mergers

Hello BrainMass OTAs,

I need help with two questions strictly related to healthcare/hospital mergers.

1. Evaluate this assertion: since 1997 there has been a steady decline in hospital mergers. A major reason for this decline has been the lack of anticipated cost savings from the mergers.

2. Also, if a health care merger goes wrong what are the chances of a successful "demerger?"

BrainMass OTA, please provide you ideas in a concise less than 150 words per question. I need this to the point, succinct and brief because OTAs tend to confuse me with verbose, too in-depth analysis in which I can draw from for my own response. Please, use as much plain English as possible.

In your response I would like you to reference the attached chapter from McLean, Robert A. (2003). Financial Management in Health Care Organizations (2nd ed.). Albany, NY: Delmar Publishers.
