HEALTH CARE MARKETS & ACCESS FOR THE UNINSURED

该项目将使用医疗支出小组调查(MEPS)的数据来研究保健市场结构和安全网结构如何影响未参保人员获得和利用医疗保健。具体地说，该项目将使用医疗保健计划来检查医疗保健市场结构和安全网对未参保人员是否有通常的护理来源以及对多种利用指标的影响，包括医生就诊、非医生就诊、住院入院和住院总日数、家庭医疗就诊、急诊室使用、预防性护理的使用、处方药的使用和医疗总支出。该项目的主要方法创新将是使用高度详细的安全网措施，其中包括个人未参保人与不同类型的安全网提供者之间的距离。此外，该项目将探索建模使用的替代方法，以说明健康保险中的动态。

This project will use data from the Medical Expenditure Panel Survey (MEPS) to study how health care market structure and the structure of the safety net affects access to and utilization of medical care by uninsured persons. Specifically, the project will use the MEPS to examine the effects of health care market structure and the safety net on whether uninsured persons have a usual source of care and on multiple measures of utilization including physician visits, non-physician visits, hospital admissions and total hospital nights, home health care visits, use of the emergency room, use of preventative care, use of prescription medicines, and total medical care expenditures. The major methodological innovation in the project will be the use of highly detailed measures of the safety net that include the distance form individual uninsured persons to different types of safety net providers. In addition, the project will explore alternative approaches to modeling use in order to account for the dynamics in health insurance.
