Changing horses midstream: the promise and prudence of practice redesign.

An emerging vision for primary care calls for the adoption of information technology and a strong business model to save a dying health care system. The authors are participants in the National Demonstration Project (NDP), a study sponsored by leading organizations in family medicine and directed by a for-profit subsidiary of the American Academy of Family Physicians, TransforMED. The NDP embraces the Future of Family Medicine Report and seeks to test the ability of existing practices to implement its basic tenets. The NDP will conclude in June 2008, but its findings and observations will likely ripple out for years. Our report is a personal reflection that looks beyond the question of whether busy practices and practitioners can change horses midstream. We ask, "Is this primary care, and is this what it needs?"
