We examined whether there was disparity in prescription medication cost-related non-adherence (CRN) by Hispanic ethnicity among Medicare enrollees.
Multivariate logistic regression, adjusting for race, other socio-demographic variables, health status, health care utilization, and patient rating of their personal physician, was used to examine association of Hispanic ethnicity with CRN using cross-sectional data from Medicare's Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey (data collected in Spring 2007).
Hispanic respondents constituted 6.9% (unweighted n=22,304) of the analytic sample (unweighted n=272,701; response rate 5 48%). Overall, 13.4% of respondents reported CRN; among Hispanics and non-Hispanics, 20.3% and 12.9% reported CRN, respectively, p<.0001. Adjusted odds ratio (95% CI) of reporting CRN in the past six months was 1.18 (1.08, 1.29) for Hispanic compared with non-Hispanic respondents.
Hispanic ethnicity was significantly associated with CRN. More research is needed to understand interventions to eliminate the disparity for this minority group.
我们研究了医疗保险参保者中西班牙裔在与处方药物费用相关的不依从性（CRN）方面是否存在差异。
利用医疗保险医疗服务提供者与系统消费者评估（CAHPS）调查（2007年春季收集的数据）的横断面数据，采用多因素逻辑回归分析，对种族、其他社会人口统计学变量、健康状况、医疗保健利用情况以及患者对其私人医生的评分进行调整，以检验西班牙裔与CRN之间的关联。
西班牙裔受访者占分析样本的6.9%（未加权n = 22,304）（未加权n = 272,701；回复率为48%）。总体而言，13.4%的受访者报告存在CRN；在西班牙裔和非西班牙裔中，分别有20.3%和12.9%的人报告存在CRN，p <.0001。与非西班牙裔受访者相比，西班牙裔受访者在过去六个月中报告CRN的调整后优势比（95%CI）为1.18（1.08，1.29）。
西班牙裔与CRN显著相关。需要更多研究来了解消除这一少数群体差异的干预措施。
