To the Editor: I was pleased to read that Dr. Mambu's personal experience with transforming his practice into a patient-centered medical home validated points I made in the commentary. I also received positive comments from others who share similar perspectives.1,2 I agree that the 6 points Dr. Mambu highlights are crucial considerations to guide refinement and implementation of the patient-centered medical home model of care and the recognition (accreditation if you will) and financing of practices. The emerging relationship among health care providers, insurance health plans, and health care purchasers is especially critical to the success of this innovation. I thank Dr. Mambu for his kind reply.
