To explore the accuracy of rehabilitation service use reports by older adults as well as variation in accuracy by demographic characteristics, time since use, duration, and setting (inpatient, outpatient, home).
Longitudinal observational study.
Participants' homes.
Community-dwelling adults ages 65 and older (N=4228) in the 2015 National Health and Aging Trends Study who were enrolled in Medicare Parts A and B for 12 months before their interview.
Not applicable.
Respondents were asked whether they received rehabilitation services in the past year and the duration and location of services. Healthcare Common Procedure Coding System codes and Revenue Center codes were used to identify Medicare-eligible rehabilitation service.
Survey-based reports and Medicare claims yielded similar estimates of rehabilitation use over the past year. Self-reported measures had high sensitivity (77%) and positive predictive value (80%) and even higher specificity and negative predictive value (approaching 95%). However, in adjusted models, sensitivity was lower for black enrollees, the very old, and those with lower education levels.
Survey-based measures of rehabilitation accurately captured use over the past year, but differential reporting should be considered when characterizing rehabilitation use in certain subgroups of older Americans.
探索老年人康复服务使用报告的准确性，以及准确性在人口统计学特征、使用时间、持续时间和地点（住院、门诊、家庭）方面的差异。
纵向观察性研究。
参与者的家中。
2015 年国家健康老龄化趋势研究中，参加 Medicare 第 A 部分和第 B 部分的 65 岁及以上的社区居住成年人（N=4228），在接受访谈前的 12 个月内已参加 Medicare。
不适用。
受访者被问及他们在过去一年中是否接受过康复服务，以及服务的持续时间和地点。医疗保健通用程序编码系统代码和收入中心代码用于确定符合 Medicare 资格的康复服务。
基于调查的报告和 Medicare 索赔得出了过去一年康复服务使用情况的相似估计。自我报告的措施具有较高的敏感性（77%）和阳性预测值（80%），甚至具有更高的特异性和阴性预测值（接近 95%）。然而，在调整后的模型中，黑人参保者、非常年老和受教育程度较低的人的敏感性较低。
基于调查的康复服务使用措施准确地捕捉了过去一年的使用情况，但在描述美国老年人某些特定亚组的康复使用情况时，应考虑差异报告。
