Managed care, capitation, and the future of nephrology.

Within the next decade, it is predicted that more than 90% of the United States population will receive its health insurance through managed care. Capitation will be the reimbursement mechanism to health care providers as the major way of controlling costs. Currently, managed care has had little experience with capitation payments for chronically ill patients, who consume large financial and physical resources. The end-stage renal disease (ESRD) population represents a vulnerable group of patients, and their care may be compromised in a capitated environment. Nephrologists will need to serve as advocates for ESRD patients through a mechanism of quality of care, driven by a continuous quality improvement model. Cost-effective delivery of care will occur as nephrologists join together to form Independent Practice Associations (IPAs). In this article, the role of a nephrologist in a capitated environment is outlined in detail, and background for the basis of managed care growth is provided as a framework for understanding the change in our health care delivery system. After formation of a nephrology IPA, there will most likely be a linkage with a management service organization (MSO). A business plan driven by the highest principles will allow nephrologists to work together as a cohesive force in accepting global risk capitated contracts. The starting point is for ESRD care, and the future includes pre-ESRD care.
