Street Medicine: Creating a "Classroom Without Walls" for Teaching Population Health

"Street Medicine" programs provide medical care to homeless populations outside of traditional healthcare institutions, literally on the street and in transitional settings where unsheltered homeless people live.

We provide a 12-step blueprint for creating a Street Medicine program in the context of a medical teaching institution.
