The health care industry has leapt into an arms race of mergers and acquisitions — but it's not clear whether, or how much, those deals would ultimately benefit patients.

Why it matters: Executives say the deals will save money and improve care. But independent research does not support those claims, and the deals raise questions about whether some companies are gaining excessive power or undermining rivals. "If it goes too far, the whole concept of competition gets eroded," said Tim Greaney, a former Department of Justice antitrust official who's now a health law professor at the University of California, Hastings.
