Partners HealthCare now owns a hospital in New Hampshire.

Massachusetts General Hospital, part of the Partners network, has acquired Wentworth-Douglass Hospital in Dover, N.H. The deal went into effect Jan. 1. This is the first out-of-state acquisition for Mass. General and Partners, the largest health care network in Massachusetts.

Wentworth-Douglass and Mass. General have been clinical partners since 2008. Last year, they agreed to tighten their relationship, saying that a full acquisition would allow the New Hampshire hospital to expand its clinical programs with the help of Mass. General’s specialists.


Wentworth-Douglass is a community hospital with 178 beds. Mass. General is the largest hospital in Massachusetts, with 999 beds. The two are about 70 miles apart.

“Together, we look forward to continuing to grow, shape and strengthen our already successful and thriving relationship to benefit patients in the region,” Mass. General’s president, Dr. Peter L. Slavin, said.

Wentworth-Douglass will keep its name, but it eventually will use a new logo that includes the Mass. General name, the hospitals said.

In approving the deal, New Hampshire Attorney General Joseph A. Foster required the hospitals to commit to increasing mental health and substance abuse services. They also must report data over time about the cost, quality, and access to care at Wentworth-Douglass.

The quick approval of the transaction stands in contrast to what Partners experienced when it sought to acquire three Massachusetts hospitals. It abandoned those deals in 2015 amid concerns that they would drive up medical costs and make Partners too powerful.

Two other hospital operators, Hallmark Health System of Medford, and Wellforce, the parent company of Tufts Medical Center in Boston, also completed a merger this week.
