Federal Trade Commission drops challenge to California hospital acquisition.

The significance of patient outmigration patterns, third-party payor reaction, and post-merger cost savings have been regularly argued by defense counsel and hospitals as important consideration in the antitrust evaluation of hospital mergers. The reliance placed by the Commission on these factors in its Ukiah decision is a welcome confirmation that the antitrust agencies are increasingly sensitive to these aspects of hospital mergers, reflecting a more sophisticated understanding of the health care market than was suggested by the staff's more mechanical evaluative approach. Hospitals and their counsel should therefore prepare for and document these factors if they anticipate antitrust agency scrutiny of a proposed acquisition or merger.
