This paper studies the effect of losing public health insurance eligibility on preventative care, self-reported health, and emergency department use. I exploit the 2005 TennCare disenrollment in which 190,000 residents–mainly non-elderly childless adults–lost public health insurance eligibility due to budget cuts. I use two surveys, the Behavioral Factor Surveillance System and the National Health Interview Survey, in a difference-in-difference methodology to study the effects of the reform. I find that the reform lead to a 4%–5% reduction in reporting having mammograms and breast exams. An increase of 20% in number of days with health incapacitation and no strong evidence of changes of emergency department visits (nor number of visits). I document margins of heterogeneity of the effects across demographic characteristics. Finally, I explore the margins of symmetry between gaining and losing public insurance by comparing estimates to those from the Affordable Care Act Medicaid Expansions.

失去公共健康保险对预防保健、健康和急诊科使用的影响：来自 TennCare 退出的证据

本文研究了失去公共医疗保险资格对预防保健、自我报告健康和急诊科使用的影响。我利用了 2005 年 TennCare 退出的情况，其中 190,000 名居民（主要是非老年人无子女的成年人）因预算削减而失去了公共医疗保险资格。我使用两个调查，行为因素监测系统和全国健康访谈调查，以差异中的差异方法来研究改革的效果。我发现改革导致进行乳房 X 光检查和乳房检查的报告减少了 4%–5%。健康丧失能力的天数增加了 20%，并且没有强有力的证据表明急诊科就诊次数（或就诊次数）发生了变化。我记录了人口特征影响的异质性边际。最后，
