Mapping Medicare Disparities"The Mapping Medicare Disparities (MMD) Tool contains health outcome measures for disease prevalence, costs, and hospitalization for 18 specific chronic conditions, emergency department utilization, readmissions rates, mortality and preventable hospitalizations. The MMD Tool provides a user friendly way to explore and better understand disparities in chronic diseases, and allows users to: 1) visualize health outcome measures at a national, state, or county level; 2) explore health outcome measures by age, race and ethnicity, gender; 3) compare differences between two geographic locations (e.g., benchmark against the national average); and 4) compare differences between two racial and ethnic groups within the same geographic area."
