Comprehensive health care (preventive, curative, rehabilitative, and environmental) for more than 930,000 eligible American Indians and Alaska Natives is the responsibility of the Indian Health Service (IHS). Since 1955, this agency of the U.S. Public Health Service has made notable progress in raising the health status of Indians and Alaska Natives, following policies outlined in Public Laws 93-638, 94-437, and 96-537. IHS operates 48 hospitals, 72 health centers, 12 school health centers, and more than 500 health stations and clinics which provide primary care, preventive health services, community health nursing, dental services, medical social work, environmental health services, and health education. Over 50% of the IHS staff is of native descent. IHS provides recruitment and career development activities for nurses, community health representatives and aides, technicians, dental/optometric assistants, mental health workers, and nutrition/dietetic workers. The most serious health related problems existing in high proportions among Indians and Alaska Natives are injuries, alcoholism, mental health problems, middle ear diseases, diabetes, nutritional deficiencies, and poor dental health. Other major health concerns are maternal and child health needs, unhealthy environmental conditions, and problems associated with aging.
