Explore the Hospital Medicine Unit

Overview

Massachusetts General Hospital’s Hospital Medicine Unit is a comprehensive Academic Hospital Medicine service with a mission of delivering outstanding inpatient care, while fostering academic advancement and professional growth for its clinicians.

The service leverages a team based model to serve over 150 patients across the hospital in a variety of inpatient care settings, including high acuity, regionalized direct patient care; moderate acuity, non-regionalized direct patient care and residency teaching teams. As it is a hospital-based service, our clinicians do not see outpatients and will instead communicate with outpatient primary care physician(s) throughout patients’ hospital stays and at discharge to ensure collaboration in care.

The service is composed of over 100 outstanding board-certified internal medicine physicians, nurse practitioners and physician assistants, supported by an exceptional administrative team, and is continuously growing. Together, our clinicians are committed to providing round-the-clock high-quality inpatient medical care and education.

What Is Hospital Medicine?

Teaching and Education

One of the core missions of Hospital Medicine is medical education. Within the Hospital Medicine Unit, we provide direct clinical teaching for medical students, physician assistant students and nurse practitioner students rotating through our medical service lines. In addition, many of our faculty attend on the Bigelow service with internal medicine residents. Our group is consistently recognized for high-quality education and robust learning experiences by our students.

We offer a robust program in faculty development for our physicians and advanced practice providers. Through a weekly lunch-time series, we offer inpatient-focused, highly applicable talks on clinical knowledge and skills from experts throughout Massachusetts General Hospital and beyond. Along with this, we offer a specialized program for new faculty throughout their first year in our group. The Hospital Medicine Unit is dedicated to helping all of our hospitalists explore their career interest through a peer-mentored Career Tracks program.
