Recent efforts to provide an annual profile of the health care quality of the nation's health care delivery system and to identify health care disparities in the population's access to and use of health care services have served to stimulate design innovations and content enhancements to the Medical Expenditure Panel Survey (MEPS).
To present a summary of the analytical objectives, design, and core content of the MEPS, and to provide an overview of the new and innovative design features that add capacity for health status and quality of care measurement and improve data quality.
The MEPS questionnaire has been expanded to include content taken from the Consumer Assessment of Health Plans Study (CAHPS) to facilitate assessments of patient experiences with health care at the national level. The survey now includes the series of questions from the SF-12 and the EuroQol 5D to improve the survey's capacity to measure health status. Additional condition-specific questions for diabetes, asthma, high blood pressure, and heart disease were added to identify the health care services received for treatment and to determine whether the care received was consistent with practice guidelines. Sample design modifications are presented, with particular emphasis given to a summary of the recent sample size increase and resultant improvements in the precision of resultant survey estimates. Attention is also given to changes in survey design, estimation, and data collection strategies that improve data quality.
近期为呈现美国医疗保健服务体系的年度医疗质量概况以及确定人群在获取和使用医疗保健服务方面的差异所做的努力，推动了医疗支出面板调查（MEPS）在设计创新和内容改进方面的发展。
介绍MEPS的分析目标、设计和核心内容，并概述其新的创新设计特点，这些特点增强了对健康状况和医疗质量的测量能力并提高了数据质量。
MEPS调查问卷已扩展，纳入了来自消费者医疗计划评估研究（CAHPS）的内容，以促进在国家层面评估患者的医疗体验。该调查现在包括来自SF - 12和欧洲五维健康量表（EuroQol 5D）的一系列问题，以提高调查测量健康状况的能力。针对糖尿病、哮喘、高血压和心脏病增加了特定病情问题，以确定接受治疗所获得的医疗保健服务，并确定所接受的治疗是否符合实践指南。介绍了样本设计的修改，特别强调了近期样本量增加的情况以及由此带来的调查估计精度的提高。还关注了调查设计、估计和数据收集策略的变化，这些变化提高了数据质量。
