The return of a Democratic administration to the White House, coupled with coronavirus disease 2019 (COVID-19) pandemic-induced contractions of job-based insurance, may reignite debate over public coverage expansion and its costs. Decades of research demonstrate that uninsured people and people with copays and deductibles use less care than people with first-dollar coverage. Hence, most economic analyses of Medicare for All proposals and other coverage expansions project increased utilization and associated costs. We review the utilization surges that such analyses have predicted and contrast them with the more modest utilization increments observed after past coverage expansions in the US and other affluent nations. The discrepancy between predicted and observed utilization changes suggests that analysts underestimate the role of supply-side constraints-for example, the finite number of physicians and hospital beds. Our review of the utilization effects of past coverage expansions suggests that a first-dollar universal coverage expansion would increase ambulatory visits by 7-10 percent and hospital use by 0-3 percent. Modest administrative savings could offset the costs of such increases.
民主党重新入主白宫,再加上 2019 年冠状病毒病(COVID-19)大流行导致就业保险收缩,可能会再次引发关于扩大公共保险范围及其成本的争论。数十年来的研究表明,没有保险的人以及需要自付费用和扣除额的人与拥有全额保险的人相比,使用的医疗服务较少。因此,对全民医疗保险提案和其他保险范围扩大的大多数经济分析都预测利用率会提高,并随之增加相关成本。我们回顾了此类分析所预测的利用率飙升情况,并将其与美国和其他富裕国家过去扩大保险范围后观察到的利用率适度增长进行了对比。预测和观察到的利用率变化之间的差异表明,分析人员低估了供应方面的限制因素(例如,医生和医院床位的数量有限)的作用。我们对过去保险范围扩大的利用效果的回顾表明,全额普及保险的扩大将使门诊就诊量增加 7-10%,住院使用量增加 0-3%。适度的行政节省可以抵消这些增长的成本。
