  • Kaiser Health Tracking Poll: September 2015

    Feature

    As the Centers for Medicare & Medicaid Services prepares to finalize a plan to pay physicians for discussing end-of-life treatment options with Medicare patients, this month’s Kaiser Health Tracking Poll finds that about 8 in 10 of the public favors Medicare and private insurance covering such discussions and about 9 in 10 say doctors should have these discussions with their patients. However, relatively few (17 percent) say they’ve had such discussions with a doctor or other health care provider, while half of the public says they would want to have such a discussion. Overall, opinion of the health care law has remained divided with similar shares reporting favorable views (41 percent) and unfavorable views (45 percent), with opinion starkly divided by party. The Kaiser Health Policy News Index also finds that the 2016 presidential election is the most widely followed news story included in this month’s Index, placing far ahead of health policy news stories.

  • Kaiser Health Tracking Poll: August 2015

    Feature

    With renewed discussion of the high cost of prescription drugs recently, the August Kaiser Health Tracking poll finds that most Americans feel that drug costs are unreasonable and that drug companies put profits before people. At the same time, the public largely values the role prescription drug companies play, with most saying that prescription drugs developed in the past two decades have made the lives of people in the U.S. better, including about 4 in 10 who say a lot better. When it comes to their views of the Affordable Care Act (ACA) this month, the American public remains divided in their opinion of the law. Those who favor repeal are divided on whether the law should be replaced with a Republican-sponsored alternative or if it should be repealed and not replaced

  • Kaiser Health Tracking Poll: January 2016

    Feature

    Despite the ongoing debate between Republican lawmakers and President Obama on the future of the 2010 health care law, the January Kaiser Health Tracking Poll finds the Affordable Care Act (ACA) is only one of many issues that may impact voting decisions. While there has been recent focus on improving the value of health care, those with insurance under 65 years old largely say the health care services they receive are at least a good value for what they pay for them. Also, in the final days of the 2016 open enrollment period, many uninsured are largely disengaged from the health care system and opportunities for coverage, with large majorities being unaware of the date for the upcoming deadline to enroll or of the fine for not having health insurance in 2016.

  • Data Note: Abbreviated January 2016 Health Tracking Poll Topline

    Feature

    This is an abbreviated topline for the upcoming January 2016 Kaiser Health Tracking Poll.  It contains the survey questions addressed in Drew Altman's column, "Candidate Policy Plans Resonate More With Democrats. Here’s Why," for The Wall Street Journal's Think Tank.

  • Kaiser Health Tracking Poll: December 2015

    Feature

    The ACA’s third open enrollment will come to a close at the end of January and the December Kaiser Health Tracking Poll finds that only 7 percent of the uninsured correctly identify this as the deadline to enroll in coverage. With Democratic presidential candidates debating the idea of Medicare-for-all, which involves creating a national health plan in which all Americans would get their insurance through an expanded version of the Medicare program, most Democrats like the idea, but very few say the issue will drive their votes in the 2016 elections. As the U.S. Senate voted to repeal the Affordable Care Act (ACA) earlier this month, more of the public views the health care law unfavorably than favorably (46 percent vs. 40 percent). In addition, the public remains divided over what Congress should do next with the law, with 35 percent supporting repeal, 14 percent supporting scaling back the law, 18 percent who say they would like to see it implemented as is, and 22 percent who say they want the law expanded.

  • Kaiser Health Tracking Poll: November 2015

    Feature

    As the problem of prescription painkiller abuse has captured greater attention from policymakers and the media, the November Kaiser Health Tracking Poll explores the public’s connection to and knowledge of the issue, as well as their views of how to address it. A surprising 56 percent of the public say they have some personal connection to the issue – either because they say they know someone who has taken a prescription painkiller that wasn’t prescribed to them, know someone who has been addicted, or know someone who has died from a prescription painkiller overdose. While views of the health care law have been narrowly divided for much of the year, this month more say they have an unfavorable view of the law than a favorable one. The poll also includes views of the uninsured during the third open enrollment period under the health care law.

  • 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.
