IN the United States several types of health care programs can be identified: singleservice care, health agency, coordinated care, and comprehensive coordinated care. Single-service care is defined in this paper as individual services provided to patients in their homes, such as those provided by the physician, visiting nurse, and physical therapist. These services historically have been provided by visiting nurse associations and public health agencies as well as by private practitioners. A health agency is a care organization which provides or arranges for skilled nursing and at least other therapeutic service to patients in their homes (1). A coordinated care program is one that is centrally administered and that through coordinated planning, evaluation, and follow-up procedures provides for physician-directed medical, nursing, social, and related services to selected patients at home (2). In order to accomplish their goals, most of these programs have used a multidisciplinary team approach. A comprehensive coordinated care program has the added element of an interdisciplinary team of all appropriate health professionals who individually and collectively evaluate the full range of patient needs. This team provides or arranges for a complete and openended service incorporating into the program any services available in the community. Home health agencies, coordinated care programs, and comprehensive coordinated care programs all meet the basic multiservice requirement for participation in Medicare. The goals of all three multiservice programs include reducing the cost of illness by providing comprehensive, high-quality, noninstitutional patient care to avoid hospitalizing the patient or confining him in a nursing or in another type of long-term care facility. All are financed under the provisions of titles XVIII and XIX of Public Law 89-97. The Erie County Coordinated Home Care Program is financed by a New York State Department of Health grant of approximately $100,000 per annum for 4 years and a single grant of $20,000 from Blue Cross-Blue Shield of Western New York, Inc. Although the program was funded in January 1964, it was not staffed until the end of 1965. In 1966 the cost per patient-day was $6.92 based on 15,785 patient-days; in 1965 the cost per patient-day was $11.50 based on 8,075 patient-days. These costs include salaries of the interdisciplinary evaluative team; administrative expenses; fees for direct service to patients (visiting nurses, health aides, and physical, speech, or occupational therapists); transMr. Roth, formerly the director ot the Erie County Department of Health's coordinated care program, is executive director of the Hospital Review and Planning Council of Western New York in Bufalo. Mr. Tarnopoll, the program's former public health social work coordinator, is director of social services at Our Lady of Victory Hospital, Lackawanna, N.Y.
