Rheumatologists on the road: a subspecialist's role in caring for the homebound.

Objective: By 2030, the number of permanently homebound individuals in the US will increase by 50% to reach 2 million. However, no medicine subspecialty consult services exist for this rising subset of the population. This pilot program establishes a rheumatology consult service for the Mount Sinai Visiting Doctors, the largest primary care academic home visit program in the nation serving more than 1,000 patients in New York City.
