From the abstract:
During and immediately after the recent recession, national health expenditures grew exceptionally slowly. During 2009–11 per capita national health spending grew about 3 percent annually, compared to an average of 5.9 percent annually during the previous ten years. Policy experts disagree about whether the slower health spending growth was temporary or represented a long-term shift. This study examined two factors that might account for the slowdown: job loss and benefit changes that shifted more costs to insured people. Based on an examination of data covering more than ten million enrollees with health care coverage from large firms in 2007–11, we found that these enrollees’ out-of-pocket costs increased as the benefit design of their employer-provided coverage became less generous in this period. We conclude that such benefit design changes accounted for about one-fifth of the observed decrease in the rate of growth. However, we also observed a slowdown in spending growth even when we held benefit generosity constant, which suggests that other factors, such as a reduction in the rate of introduction of new technology, were also at work. Our findings suggest cautious optimism that the slowdown in the growth of health spending may persist—a change that, if borne out, could have a major impact on US health spending projections and fiscal challenges facing the country.
