背景技术背景：本文提出的分析探讨了多年的能力，医疗保险当前Beneficiary Survey（MCBS）。方法：我们系统地回顾了文献的方法学方法，在研究中使用多年的MCBS和分类研究的研究设计，使用调查抽样权重，方差调整。然后，我们复制的方法，在一个实证演示功能状态（日常生活活动（ADL）和2005-2007 MCBS data.RESULTS：在系统性综述中，我们确定了22个汇总，17个重复的横截面，和17个纵向研究。不到一半的研究明确描述了加权方法或方差估计。在实证论证中，我们发现，不同的研究设计和加权方法将产生统计上不同的estimation.CONCLUSION：有多种方法时，使用多年的MCBS，其中一些提供有偏见的结果。研究需要改进，以描述使用这些复杂数据的方法和首选方法。
BACKGROUND: The analysis presented in this paper examines the multi-year capacity of the Medicare Current Beneficiary Survey (MCBS).METHODS: We systematically reviewed the literature for methodological approaches in research using multiple years of the MCBS and categorized the studies by study design, use of survey sampling weights, and variance adjustments. We then replicated the approaches in an empirical demonstration using functional status (activities of daily living (ADL) and 2005-2007 MCBS data.RESULTS: In the systematic review, we identified 22 pooled, 17 repeated cross-sectional, and 17 longitudinal studies. Less than half of these studies explicitly described the weighting approach or variance estimation. In the empirical demonstration, we showed that different study designs and weighting approaches will yield statistically different estimates.CONCLUSION: There is a variety of methodological approaches when using multiple years of the MCBS, and some of them provide biased results. Research needs to improve in describing the methods and preferred approaches for using these complex data.
