The Commonwealth Fund. Organizing the U.S. Health Care Delivery System for High Performance. http://www.commonwealthfund.org/usr_doc/Shih_organizingushltcaredeliverysys_1155.pdf.

This report from The Commonwealth Fund Commission on a High Performance Health System examines fragmentation in our health care delivery system and offers policy recommendations to stimulate greater organization—established mechanisms for working across providers and care settings. Fragmentation fosters frustrating and dangerous patient experiences, especially for patients obtaining care from multiple providers in a variety of settings. It also leads to waste and duplication, hindering providers’ ability to deliver high-quality, efficient care. Moreover, our fragmented system rewards high-cost, intensive medical intervention over higher-value primary care, including preventive medicine and the management of chronic illness. The solutions are complex and will require new financial incentives, changes to the regulatory, professional, and educational environments, and support for new infrastructure. But as a nation, we can no longer tolerate the status quo of poor health system performance. Greater organization is a critical step on the path to higher performance.
