Abstract
The incentives and structure of health care in the United States produce exactly what we should expect in the quality of care for chronic disease: highly variable patterns of care and widespread failure to implement evidence-based best practices. The persistent inability of providers to improve patterns of practice is due in part to the lack of a “business case for quality.” Providers cannot anticipate that quality improvements will result in higher prices, increased volume, or decreased costs. However, signs of a business case for quality are emerging, fueled by cost pressures, the increased availability of data, informed consumers, and public- and private-sector purchaser initiatives.
