  • Kaiser Health Policy News Index: April 2014

    Feature

    The Kaiser Health Policy News Index is designed to help journalists and policymakers understand which health policy-related news stories Americans are paying attention to, and what the public understands about health policy issues covered in the news. This month’s Index finds that the public followed the missing Malaysia Airlines flight, the shooting at the Fort Hood army post, and the conflict between Ukraine and Russia, more closely than any health policy news stories. Among health policy news, the most closely-followed story was coverage of how many people have enrolled in health insurance options under the Affordable Care Act (ACA), which just over half the public reports following “very” or “fairly” closely.

  • Kaiser Health Tracking Poll: June 2015

    Feature

    Given recent news about some high-cost prescription drugs and the debate about who should pay for them, this month’s Kaiser Health Tracking Poll has a special focus on the issue. Nearly three-quarters of the public think that the cost of prescription drugs is unreasonable. Americans place much of the blame with the drug companies saying they set prices too high and that company profits are a major factor in drug pricing. The poll also finds that most of the public still hasn’t heard much about the Supreme Court case on whether people in states with federal marketplaces are eligible for financial assistance to purchase health insurance. Most feel that Congress and states should act if the Court rules for the plaintiffs, but there is no agreement among partisans.

  • Kaiser Health Policy News Index: April 2015

    Feature

Of the stories asked about this month, the one that garnered the most attention was coverage of the white police officer charged with the murder of an unarmed black man in South Carolina. Over half report closely following other stories, including the Germanwings plane crash in the French Alps, a new religious freedom law in Indiana that allows business owners to refuse service to gay customers, negotiations over Iran’s Nuclear Program, and a terrorist attack by Islamic militants at a university in Kenya. The only non-health story to receive less attention than the health stories this month was coverage of the Congressional Republican budget proposals, followed closely by just over a third of the public.

  • Kaiser Health Tracking Poll: April 2015

    Feature

    This month’s Kaiser Health Tracking Poll finds public opinion of the Affordable Care Act (ACA) continues to be almost evenly split The poll also asks about health care priorities for the President and Congress, and the concern that comes out on top for Democrats, Republicans and independents alike is making sure that high-cost drugs for chronic conditions are affordable to those who need them. Other than high-cost prescription drugs, Democrats, Republicans and independents have different ideas of their top priorities in health care. The poll also assesses Americans' use of comparative price and quality information about doctors, hospitals and health plans.
