  • National Survey of Physicians Part I: Doctors on Disparities in Medical Care

    Other Post

    Selected findings from the Kaiser Family Foundation's forthcoming National Survey of Physicians reveal that most physicians are aware of racial disparities in medical treatment for specific conditions, but they don't believe it is a widespread problem. In sharp contrast, African American physicians disagree with their fellow physicians with nearly eight in ten (77%) believing race and ethnicity impact how people are treated at least somewhat often. Physicians see insurance status as a key determinate of…

  • A Challenge for States: Assuring Timely Access to Optimal Long-Term Services and Supports in the Community

    Issue Brief

    The Medicaid program is a major payer for long-term services and supports (LTSS) in the United States, accounting for 40 percent of total spending for long-term services and supports. The federal government has played an active role in sponsoring initiatives to promote a shift to community-based care; and evidence from several states suggests that providing care in the community can be less expensive than providing institutional care. The Affordable Care Act (ACA) provides incentives for…

  • Pulling it Together: The Most Popular Provision in the ACA?

    Perspective

    In our most recent monthly tracking poll, we asked the American people what elements of the health reform law they like and dislike. Surprisingly, the runaway favorite was a relatively obscure requirement that health plans provide consumers with a short, easy to understand description of their benefits and coverage. Sixty percent of the American people gave this requirement for greater transparency in health insurance benefits a very favorable rating, the only provision in the law…

  • Pulling it Together: Business and Health Care Costs

    Perspective

    Hidden away on page 218 of our annual Employer Health Benefits Survey is a table that shows what employers think of the main strategies they have to control health care costs.  More specifically, the table shows what the person in the firm responsible for its health benefits thinks, which is whom we survey.  The short answer is, employer confidence in their own ability to control costs is not high. Not more than about a quarter…
