Advanced home health care.

Home health care in the United States is growing rapidly, as reflected in numbers of persons treated and national expenditures for care. Recent growth in this sector reflects the emergence of 'high-tech' care, such as intravenous infusion therapy, total parenteral nutrition and home dialysis. This focus on device-based therapy detracts from a larger issue, the efficient production of medical care subject to acceptable levels of cost and quality. The structure of payment and quality assurance mechanisms will shape the emergence of advanced home health care in the 1990's and beyond.
