A description from their site:
Kaiser Health News (KHN) is a nonprofit news organization committed to in-depth coverage of health care policy and politics.
KHN’s mission is to provide high-quality coverage of health policy issues and developments at the federal and state levels. In addition, KHN covers trends in the delivery of health care and in the marketplace.
Among our goals: provide new opportunities for health care journalists to produce in-depth work and a new vehicle to distribute it through collaborations with major news organizations and on this Web site. This Web site also features daily summaries of major health care news from across the nation, as well as original videos and a broad range of commentary from contributing writers and issues.
KHN is a major program of the Kaiser Family Foundation, a non-profit private operating foundation, based in Menlo Park, Calif., dedicated to producing and communicating the best possible analysis and information on health issues.
