"There is a professional, economic, and ethical imperative to eliminate health disparities. We have the means to find and implement solutions by holding ourselves, and others, accountable," wrote study author Dr. Neil Powe of the Johns Hopkins Medical Institutions in Baltimore, who suggested a number of steps that can be taken by doctors and others.
