Marital status is recognized as an important social determinant of health, income, and social support, but is rarely available in administrative data. We assessed the feasibility of using exact address data and zip code history to identify cohabiting couples using the 2018 Medicare Vital Status file and ZIP codes in the 2011-2014 Master Beneficiary Summary Files. Medicare beneficiaries meeting our algorithm displayed characteristics consistent with assortative mating and resembled known married couples in the Health and Retirement Study linked to Medicare claims. Address information represents a promising strategy for identifying cohabiting couples in administrative data including healthcare claims and other data types.
婚姻状况被视为健康、收入和社会支持的重要社会决定因素，但行政数据中很少有这方面的信息。我们利用2018年医疗保险生命状态文件和2011 - 2014年主要受益人汇总文件中的邮政编码，评估了使用精确地址数据和邮政编码历史来识别同居伴侣的可行性。符合我们算法的医疗保险受益人表现出与选择性婚配一致的特征，并且类似于与医疗保险理赔相关联的健康与退休研究中已知的已婚夫妇。地址信息是在包括医疗保健理赔和其他数据类型在内的行政数据中识别同居伴侣的一种有前景的策略。
