In January 2004, the Institute of Medicine (IOM) hosted the 1st Annual Crossing the Quality Chasm Summit, convening a group of national and community health care leaders to pool their knowledge and resources with regard to strategies for improving patient care for five common chronic illnesses. This summit was a direct outgrowth and continuation of the recommendations put forth in the 2001 IOM report Crossing the Quality Chasm: A New Health System for the 21st Century. The summit's purpose was to offer specific guidance at both the community and national levels for overcoming the challenges to the provision of high-quality care articulated in the Quality Chasm report and for moving closer to achievement of the patient-centerd health care system envisioned therein.
