Integrated Health Interview Series Competing Continuation

 该提案旨在为综合健康访谈系列（IHIS）继续提供资金，该系列是美国最全面的描述美国人口健康的数据和元数据来源。这一延续将通过增加医疗支出专题调查的家庭部分来扩大和丰富IHIS，这是关于人口保健使用和支出的最完整信息来源。这项倡议是在一个关键时刻提出的。美国医疗保健系统正在经历前所未有的变化，以应对平价医疗法案。新的努力有望将医疗保健系统从临床急性护理模式转变为以人口为基础的改善健康的重点。IHIS数据系统将使科学家和政策研究人员能够轻松访问研究变化并做出明智决策所需的数据。在过去的十年中，IHIS项目成功地协调了50年的NHIS数据，包括550万人记录和12，000多个描述美国人口健康和健康行为的变量，并通过用户友好的网络应用程序免费提供这些数据。将MEPS数据添加到IHIS并更新Web访问系统将大大增加这一关键健康数据基础设施的功能。MEPS的内容是对NHIS的补充; MEPS收集个人医疗保健使用和成本的详细信息，使研究人员能够估计美国平均人均医疗保健支出和研究支出的医疗条件和医疗保健服务类型。MEPS的数据是纵向的，与NHIS一致;选择对前一年的NHIS做出答复的家庭的子样本参加MEPS，并在两年期间进行五次访谈。扩展后的IHIS数据库将增加22年的卫生支出微观数据（1996-2018），提供约52万名NHIS受访者的健康和医疗保健纵向数据，以及5年的NHIS微观数据（2014-2019）。这一延续项目将开发新的访问工具，以利用MEPS的纵向维度，建立两项调查之间的联系，并创建2,000多个综合变量。实现这一目标将需要将MEPS数据重组为一致的格式，为每个MEPS文件创建全面的机器可读文档，并开发描述文件之间关系的统一元数据。扩大和升级后的IHIS将提供宝贵的在线数据资源，在美国医疗保健历史的关键时刻，减少对美国人口健康和医疗保健服务使用和成本进行研究的障碍。

 DESCRIPTION (provided by applicant): This proposal seeks continuation funding for the Integrated Health Interview Series (IHIS), the nation's most comprehensive source for data and metadata describing the health of the U.S. population. The continuation will expand and enrich IHIS by adding the Household Component of the Medical Expenditure Panel Survey (MEPS), the most complete source of information on population healthcare use and expenditures. This initiative comes at a critical time. The U.S. healthcare system is undergoing unprecedented changes in response to the Affordable Care Act. New efforts promise to transform the healthcare system away from a clinical acute care model to a population-based focus on improved health. The IHIS data system will allow scientists and policy researchers to easily access the data needed to study change and to make informed decisions. Over the past ten years, the IHIS project has successfully harmonized 50 years of NHIS data, including 5.5 million person records and over 12,000 variables describing the health and health behaviors of the U.S. population, and made these data freely available via a user-friendly web application. Adding MEPS data to IHIS and updating the web access system will greatly multiply the power of this critical piece of health data infrastructure. The content of MEPS is complimentary to that of the NHIS; MEPS collects detailed information on individual healthcare use and costs, allowing researchers to estimate average U.S. per capita healthcare spending and study expenditures by medical condition and type of healthcare service. The MEPS data are longitudinal and linkable to the NHIS; a subsample of households responding to the previous year's NHIS is selected to participate in the MEPS and is interviewed five times over a two-year period. The expanded IHIS database will add 22 years of health expenditure microdata (1996-2018), providing longitudinal data on health and healthcare for approximately 520,000 NHIS respondents, and 5 years of NHIS microdata (2014-2019). This continuation project will develop new access tools to capitalize on the longitudinal dimension of the MEPS, build linkages across the two surveys, and create more than 2,000 integrated variables. Accomplishing this goal will require restructuring the MEPS data into a consistent format, creating comprehensive machine- readable documentation of each MEPS file, and developing harmonized metadata describing the relationship between files. The expanded and upgraded IHIS will provide an invaluable on-line data resource that will reduce barriers to research on the health of the U.S. population and the use and costs of healthcare services at a critical point in the history of American healthcare.
