This article describes the forces behind the resurgence of home-based primary care (HBPC) in the United States and then details different HBPC models. Factors leading to the resurgence include an aging society, improved technology, an increased emphasis on home and community services, higher fee-for-service payments, and health care reform that rewards value over volume. The cost savings come principally from reduced institutional care in hospitals and skilled nursing facilities. HBPC targets the most complex and costliest patients in society. An interdisciplinary team best serves this high-need population. This remarkable care model provides immense provider satisfaction. HBPC models differ based on their mission, target population, geography, and revenue structure. Different missions include improved care, reduced costs, reduced readmissions, and teaching. Various payment structures include fee-for-service and value-based contracts such as Medicare Shared Savings Programs, Medicare capitation programs, or at-risk contracts. Future directions include home-based services such as hospital at home and the expansion of the home-based workforce. HBPC is an area that will continue to expand. In conclusion, HBPC has been shown to improve the quality of life of home-limited patients and their caregivers while reducing health care costs.

Home-based primary care (HBPC) improves the lives of high-cost, frail, homebound patients and their caregivers while reducing costs by keeping patients at home and reducing the use of hospitals and nursing homes. Several forces are behind the resurgence of HBPC, including the rapidly aging population, advancements in portable medical technology, evidence showing the value of HBPC, and improved payments for HBPC. There are 2 million to 4 million patients who could benefit from HBPC, but only 12% are receiving it. The number of these patients is expected to double over the next two decades. This requires a larger and better prepared HBPC workforce, making St. Clair and colleagues’ article published within this same issue very timely. They showed residents exposed to HBPC had increased interests in providing HBPC in the future. They also found HBPC training fulfilled all 6 Accreditation Council of Graduate Medical Education core competencies and at least 16 of the 22 Family Medicine Milestone Project subcompetencies. Such medical education curricula are necessary to sufficiently develop a future workforce capable of appropriately providing HBPC to an increasing number of patients.
