The Department of Health and Human Services (HHS) has developed a new web-based tool, the Health System Measurement Project, which will allow policymakers, providers, and the public to develop consistent data driven views of changes in critical U.S. health system indicators. The project brings together datasets from across the federal government that span a variety of topical areas, such as access to care, cost and affordability, prevention, and health information technology. The indicators are presented by population characteristics, such as age, sex, income level, insurance coverage, and geography.
