The United States is in the midst of the most sweeping health insurance expansions and market reforms since the enactment of Medicare and Medicaid in 1965. Our 2013 survey of the general population in eleven countries—Australia, Canada, France, Germany, the Netherlands, New Zealand, Norway, Sweden, Switzerland, the United Kingdom, and the United States—found that US adults were significantly more likely than their counterparts in other countries to forgo care because of cost, to have difficulty paying for care even when insured, and to encounter time-consuming insurance complexity. Signaling the lack of timely access to primary care, adults in the United States and Canada reported long waits to be seen in primary care and high use of hospital emergency departments, compared to other countries. Perhaps not surprisingly, US adults were the most likely to endorse major reforms: Three out of four called for fundamental change or rebuilding. As US health insurance expansions unfold, the survey offers benchmarks to assess US progress from an international perspective, plus insights from other countries’ coverage-related policies.
