The Indian Health Service, a federal agency that serves Native Americans, failed to meet minimum U.S. standards for medical facilities in some of the poorest areas of the country, an investigation by The Wall Street Journal has found. It turned away gravely ill patients and caused unnecessary deaths. These IHS hospitals repeatedly failed inspections, shut down services and lost access to crucial federal funds. The crisis comes after the IHS and the Department of Health and Human Services failed to address warnings over many years about neglect and dire conditions at some of these facilities.
