Published in Health Affairs, this paper examines the effects of the patient-centered medical home model as a key vehicle to improve the quality of health care and to control costs by studying a Seattle-based Group Health Cooperative with a medical home pilot. The results indicate improvements in patients’ experiences, quality, and clinician burnout through two years. Compared to other Group Health clinics, patients in the medical home experienced fewer emergency visits and fewer hospitalizations. The results suggest an estimated total savings of $10.3 per patient per month. Policy recommendations for other health care settings are offered.
