In 2021, 81 percent of all Medicare Advantage enrollees are in plans that receive a bonus payment from Medicare based on star quality ratings (or because they are new), substantially higher than the share in 2015 (55 percent). Annual bonus payments from the federal government to Medicare Advantage insurers have increased correspondingly, quadrupling from $3 billion in 2015 to $11.6 billion in 2021.
This Health Policy 101 chapter explores the performance of the U.S. health system on a number of cost, outcomes, and quality measures by comparing it with those in similarly large and wealthy OECD nations. It highlights that despite significant spending, Americans have shorter life expectancies and encounter more barriers to health care, influenced by both the health system's structure and broader socioeconomic factors.
A new brief on the Peterson-Kaiser Health System Tracker finds that the quality of the U.S. health system is improving in many areas, but comparable countries continue to outperform the United States on key measures.
The quality of the U.S. health system is improving in many areas, but comparable countries continue to outperform the United States on key measures. In this brief on the Peterson-Kaiser Health System Tracker, analysts from the Kaiser Family Foundation compile an overall picture of health care quality in the United States, using the best available data from numerous sources on health outcomes, quality of care, and access to services.
This Data Spotlight reviews national and state-level enrollment trends as of March 2015 and examines variation in enrollment by plan type and firm. It analyzes the most recent data on premiums, out-of-pocket limits, Part D cost-sharing for drugs, and plans’ quality ratings for Medicare Advantage enrollees.
This chart collection compare health outcomes, quality of care, and access to services between the U.S. and peer countries. While inconsistent and imperfect metrics make it difficult to firmly assess system-wide health quality in the U.S., a review of the available data prior to the onset of the COVID-19 pandemic suggests that in most of these measures, the U.S. has lagged behind comparably large and wealthy countries.
This issue brief presents national and state-level analysis of nursing homes based on the Five-Star Quality Rating System, recently updated by the Centers for Medicare and Medicaid Services (CMS) to help consumers compare nursing homes when selecting one for themselves or their family members. The issue brief finds that more than one-third (36%) of the nation’s 15,500 nursing homes certified by Medicare or Medicaid received relatively low ratings of 1 or 2 stars (out of a possible 5 stars). In 11 states, at least 40 percent of nursing homes in the state have 1- or 2-star ratings. In 23 states, however, at least half of the nursing homes have 4- or 5- star ratings. This issue brief discusses relevant policy considerations regarding nursing home quality—a serious issue in light of the vulnerability of the nursing home population and recent reports of problems arising from inadequate staffing, fire safety hazards, and substandard care.

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.
