In July 2017, CEO Kevin Tabb of Boston's Beth Israel Deaconess Medical Center announced his plan to consolidate 11 Massachusetts hospitals under a common management structure. These hospitals collectively generated $5 billion in patient revenue and 25% of privately-insured hospital stays in the state. The merger would create a credible competitor to Partners Healthcare, the state's dominant health care provider, but would potentially reduce competition and raise prices. State regulators were assessing the merger, and Tabb needed to argue its merits.
