Competitive Advantage
MGB returned to positive operating margin in fiscal 2024 after pandemic-era losses. The system was the first in Massachusetts ordered to file a system-wide Performance Improvement Plan by state regulators. MGB's resident and fellow physicians successfully unionized in 2023 and ratified their first system-wide contract in May 2025. The departure of Dana-Farber Cancer Institute's adult inpatient oncology services represents a significant loss for one of MGB's flagship institutions, Brigham and Women's Hospital.
