Home-based medical care (HBMC) aims to meet the complex medical and functional needs of the homebound elderly with multimorbidity and mobility impairment by providing comprehensive and longitudinal primary care. Unlike South Korea where home visit service by a physician has completely vanished since the late 1990s, the HBMC in the U.S. has continued to expand and evolve as a new demand for HBMC has increased over the years. The favorable clinical and functional impact and cost-saving effect of the home visit service have been attributed to the resurgence of HBMC in the U.S. The article describes the crucial components of HBMC and driving forces for its growth in the U.S., and these qualities may need to be incorporated into newly implemented HBMC initiatives in South Korea.
