The Harvard MGH Medicine-Pediatrics Program began in 1989 as the Massachusetts General Hospital (MGH) Med-Peds Residency. In 1995, the original MGH med-peds program merged with the Brigham and Women’s Hospital (BWH) and Children’s Hospital Boston (CHB) Med-Peds Residency (formed in 1994), to become the Harvard Combined Med-Peds Program (HCMP), encompassing all four core programs. In 2006, the ACGME mandated to all med-peds programs across the country that they have only one parent medicine program and one parent pediatric program. This necessitated the division of the Harvard Combined Program into the Harvard MGH Med-Peds Program and the Harvard BWH/CHB Med-Peds Program. The programs continue to work together by jointly hosting medical student med-peds interest group events.
