Mass General Brigham

What Mass General Brigham does

Mass General Brigham is a 501(c)(3) non-profit integrated healthcare delivery system headquartered in Somerville, Massachusetts, formed in 1994 through the merger of Massachusetts General Hospital and Brigham and Women's Hospital (originally as Partners HealthCare, rebranded in 2019). The system operates 14+ hospitals and numerous outpatient, urgent care, rehabilitation, and home-hospital sites across Massachusetts and New Hampshire, including flagship academic medical centers Mass General and Brigham and Women's, alongside specialty institutions such as Mass Eye and Ear, McLean Hospital, the Spaulding Rehabilitation network, and community hospitals from Martha's Vineyard to Wentworth-Douglass. It also owns a health plan and a specialty pharmacy. The system serves approximately 2.5 million patients annually through an integrated care delivery model with Harvard Medical School teaching affiliations, runs one of the largest hospital-based research enterprises in the U.S. with an annual research budget of nearly $2 billion, and has 3,700+ ongoing clinical trials.

Revenue is generated through five streams: patient care services billed to insurers and patients (subject to CMS machine-readable charge disclosures), research grants and clinical trial funding (NIH, pharma), graduate medical education, technology commercialization and venture investments via Mass General Brigham Innovation, and insurance premiums through Mass General Brigham Health Plan. The system is governed as a non-profit with no parent company or equity ownership; CEO Anne Klibanski earned $8.4M in fiscal year 2024 and the top 14 executives combined for $35.9M.

The technology stack includes an enterprise EHR backbone, the Patient Gateway patient portal (Epic MyChart-based), and a substantial proprietary AI portfolio: the APOLLO foundation model trained on 25.2 billion medical events, the BRIDGE multilingual clinical LLM benchmark with a 100+ model leaderboard, FaceAge (computer-vision mortality predictor), the RECTIFIER clinical-trial eligibility screener now spun out into AIwithCare, an 88%-accuracy intimate-partner-violence risk model, polygenic risk scores for 8 cardiovascular conditions validated on the 53,000-patient Biobank, AI scribes reducing clinician burnout by 21.2% over 84 days, and the Care Connect AI-powered telehealth platform built with K Health. AI deployment is led by Chief Health Information Officer Rebecca Mishuris and Chief Information and Digital Officer Jane Moran under a documented cautious, evidence-based governance posture.
