The Effect of Medicaid on Health Care Consumption of Young Adults
研究发现，年轻成年人在19岁后失去医疗补助资格，导致医疗使用量下降超60%，其中三分之二是门诊减少，住院支出也大幅下降。
All states provide Medicaid until the age of 19 years. After 19 years, young adults may become ineligible for Medicaid. Using the Medical Expenditure Panel Survey, we find that the resulting loss of Medicaid coverage causes substantial changes to the level and composition of health care use. The total number of visits to health care providers falls by over 60%, two-thirds of which is due to a decline in office visits. Expenditures, in particular inpatient expenditures, also appear to fall sharply.
