Several Boston hospitals that oppose the recent agreement between Partners HealthCare System and the Massachusetts Attorney General to acquire South Shore Hospital filed a letter in court to participate in the judicial process, the Boston Business Journal reported. Rival hospitals, including Beth Israel Deaconess Medical Center, Atrius Health, Lahey Health System and Tufts Medical Center, argue the acquisition is bad for the healthcare system as a whole and will drive up prices. They also charge that there wasn't enough public input throughout the agreement process. The competitors also claim the agreement was "too complex to be deciphered quickly by a judge that did not have expertise in healthcare," according to the Journal. The agreement allows the purchase but prevents Partners from contracting with affiliate physician groups that are not part of its owned hospitals for 10 years, caps health costs at the rate of inflation across the entire Partners network through 2020 and caps physician growth for five years, among other conditions.
