Patient Age Group

Edit Profile


Jeff Greenwald, MD, is a native of Chicago and subsequently graduated from Washington University in St. Louis. Thereafter, he attended Harvard Medical School before returning to St. Louis to complete Internal Medicine residency at Barnes Hospital. Thereafter, Dr. Greenwald moved to Oxford, England, where he practiced as a Specialist Registrar at the John Radcliffe Hospital, spending time in both inpatient medicine and the ICU.

After almost a year overseas, Dr. Greenwald returned to the US and became the first hospitalist at Boston Medical Center, the hospital affiliated with Boston University School of Medicine. There he stayed for a decade becoming their first director of the Hospital Medicine Unit. His work there heavily focused on medical education and quality improvement, working on projects to improve influenza vaccination, medication reconciliation, ACS care, pain management and VTE prophylaxis. His work in HIV testing there resulted in being requested to offer advice to the CDC on their inpatient HIV testing recommendations. He also helped to develop and implement Project RED (a randomized trial of a care transition intervention), and Project BOOST (a national QI project to improve care transitions across the US). He ran an AHRQ funded conference on medication reconciliation, advised UHC, and contributed to the NQF metric on all cause readmissions, subsequently adopted by CMS.

In 2009, Dr. Greenwald moved to the Massachusetts General Hospital to join the Inpatient Clinician Educator Service as a teaching hospitalist and is a member of the Core Educator Faculty of the Department of Medicine. He is an Associate Professor of Medicine at Harvard Medical School and served as the lead physician for Partners Healthcare's High Performance Medicine Team on Readmissions until 2014.  He continues to work closely with the MGH Readmissions Care Redesign Committee and was a principal developer of the novel readmission risk indicator MGH now uses.
