This study estimates the effect of universal coverage on the use and cost of health services by the uninsured. Adults lacking insurance for a full year have about 60 percent as many ambulatory contacts and about 70 percent of the inpatient hospital days they would have if they were covered by insurance. This "access gap" is only slightly smaller for children. Providing universal coverage would increase ambulatory contacts and inpatient days by less than 4 percent a year. The dollar cost of these new services is estimated to be $19.9 billion--a 2 percent increase in health spending.
本研究估计了全民医保对未参保者医疗服务使用情况及成本的影响。全年未参保的成年人的门诊就诊次数约为参保时的60%，住院天数约为参保时的70%。儿童的这种“就医差距”仅略小。提供全民医保将使门诊就诊次数和住院天数每年增加不到4%。这些新增服务的成本估计为199亿美元，即医疗支出增加2%。
