In 2018, spending on healthcare accounted for 17.7 percent of the United States gross domestic product, yet the majority of this spending was concentrated in a small percentage of the population. Medical Expenditure Panel Survey (MEPS) data show that about 13 percent of the U.S. civilian noninstitutionalized population had no personal healthcare expenditures in 2018. On the other hand, only 5 percent of the population accounted for nearly half of healthcare spending. This spending includes all sources of payments for medical care, including private insurance payments, Medicare, Medicaid, out-of-pocket spending, and other sources. In this Statistical Brief, data from the Agency for Healthcare Research and Quality (AHRQ) Medical Expenditure Panel Survey Household Component (MEPS-HC) are used to describe the overall concentration of healthcare expenditures across the U.S. civilian noninstitutionalized population in 2018. In addition, the most commonly treated conditions among top spenders are identified, and the shares of spending by age group, race/ethnicity, type of medical service, and source of payment are compared across the distribution. All differences discussed in the text are statistically significant at the 0.05 level.
2018年，医疗保健支出占美国国内生产总值的17.7%，然而，这些支出的大部分集中在一小部分人口身上。医疗支出面板调查（MEPS）数据显示，2018年约13%的美国非机构化平民人口没有个人医疗保健支出。另一方面，仅5%的人口占了近一半的医疗保健支出。这笔支出包括医疗保健的所有支付来源，包括私人保险支付、医疗保险、医疗补助、自付费用以及其他来源。在本统计简报中，医疗保健研究与质量局（AHRQ）医疗支出面板调查家庭部分（MEPS-HC）的数据用于描述2018年美国非机构化平民人口医疗保健支出的总体集中情况。此外，还确定了高支出人群中最常见的治疗疾病，并比较了不同分布情况下按年龄组、种族/族裔、医疗服务类型和支付来源划分的支出份额。文中讨论的所有差异在0.05水平上均具有统计学意义。
