An overview of pediatric home care issues reveals the breadth and scope of services available to permit pediatricians to provide care at home. This care option has undergone explosive growth and represents one of the fastest-growing health expenditures. Paradoxically, direct physician involvement in the home has been limited during this expansion because of the way home care has been designed and organized with inadequate reimbursement for physician participation, and lack of awareness by, and education of, physicians concerning their roles and responsibilities. The rationale for physician involvement in home care includes the need for determination and reevaluation of the medical necessity of home care services. Future changes in health care delivery and payment will encourage even more consideration of alternative care sites. Physician participation in program and protocol design will facilitate and encourage the appropriate use of the home as a care setting. For the pediatrician to know about home care requires the development of a curriculum to be implemented in academic centers for physicians-in-training and in professional associations for continuing medical education. This curriculum should enable physicians to become primary participants in home care and should lead to research opportunities to evaluate the benefits of home care.
