A carefully managed electronic data warehouse is a key component of improved patient care in any health-care practice and is surprisingly easy to build on and improve, once you begin the implementation process. Those were the key points of “Use of Registry Tools to Improve Care,” presented by David Howes, MD, in San Diego, California, on October 7, 2013, at the annual conference of the Medical Group Management Association. Howes is president and CEO of Martin's Point® HealthCare (Portland, Maine), a nonprofit health-care organization.
