Clinical and Scholarly Activities

The VA St. Louis Health Care System is composed of seven different sites of care throughout the greater St Louis region. Each location has state of the art exam/treatment tables, computers, and other necessary equipment. One of the unique features of VA STL is our ability to offer our residents a variety of patient demographics from the city, to suburban, and rural. Additionally, we are a Whole Health Flagship site that is slowly transforming health care in VA. Our residents become knowledgeable in Whole Health as they learn through the lens of our veterans as they rotate through the different components of whole health and VA ST Louis HCS. Later through opportunities to recommend and deliver classes our resents become champions of Whole Health and fully understand the importance of this healthcare transformation Residents will have library support through VASTLHCS, VISN 15 Online Library, and through Logan University. In addition, the resident will rotate through Logan University health care systems, participate in didactic activities throughout their trimesters, and post graduate course work.

Residents carry a 65% caseload with time devoted to clinical rotations, didactic coursework, professional presentations, scholarly projects, and mentorship of health professional trainees.  Primarily, this is a clinical residency as part of Whole Health, however, the resident will spend considerable time on rotations across VA St Louis and in the classroom setting at  Logan University.  One of the features of the VA ST Louis residency is our rotations and immersion in resident life.  Each resident will have the opportunity to rotate with other residents through various departments including, Whole Health, Primary Care, Specialty Care (Orth, Neuro, Rheumatology), Palliative Care, Emergency Dept, and Physical Medicine and Rehabilitation.  Additionally, residents will spend time being mentored and putting together research projects and scholarly work for submission to conferences and for presentations throughout VA ST Louis and Logan University.  This combination of experience will ensure residents are successful in transitioning to a VA position, Private hospital, or academia.
