The objectives of this study were to examine the relationship between prescription benefit status and access to medications among Medicare beneficiaries with hypertension, congestive heart failure, coronary artery disease, and diabetes and to determine how income, wealth, and health status influence this relationship.
We analyzed survey and administrative data for 4492 Medicare + Choice enrollees aged 67 and above enrolled in a predominantly group-model health maintenance organization in 2000. Outcome measures included difficulty affording medications, methods of coping with medication costs including obtaining medicines from another country, using free samples, and stretching out medications to make them last longer. Independent variables included prescription benefit status, income, wealth measures, health status, and out-of-pocket prescription drug spending.
Lacking a prescription benefit was independently associated with difficulty affording medications (25% of those without a benefit vs. 17% with a benefit) and coping methods such as stretching out medications. Lower income, lower assets, and worse health status also independently predicted greater difficulty as measured by these outcomes; there was no effect modification between these factors and benefit status. Relative to national figures, out-of-pocket spending in this setting was quite low, with only 0.2 and 13% of those with and without a benefit, respectively, spending over 100 dollars per month. Higher out-of-pocket spending predicted greater difficulty affording medications but not stretching out medications.
Efforts to improve medication accessibility for older Americans with chronic conditions need to address not only insurance coverage but also barriers related to socioeconomic status and health status.
本研究的目的是调查高血压、充血性心力衰竭、冠状动脉疾病和糖尿病的医疗保险受益人的处方福利状况与药物可及性之间的关系,并确定收入、财富和健康状况如何影响这种关系。
我们分析了2000年在一个主要为团体模式的健康维护组织中登记的4492名67岁及以上的医疗保险 + 选择计划参保者的调查和管理数据。结果指标包括支付药物费用困难、应对药物费用的方法,包括从另一个国家获取药物、使用免费样品以及延长药物使用时间以使其持续更长时间。自变量包括处方福利状况、收入、财富指标、健康状况和自付处方药支出。
缺乏处方福利与支付药物费用困难(无福利者中有25%,有福利者中有17%)以及诸如延长药物使用时间等应对方法独立相关。较低的收入、较少的资产和较差的健康状况也独立预测了这些结果所衡量的更大困难;这些因素与福利状况之间没有效应修正。相对于全国数据,在这种情况下自付支出相当低,有福利和无福利者中分别只有0.2%和13%的人每月支出超过100美元。较高的自付支出预测支付药物费用困难更大,但与延长药物使用时间无关。
改善患有慢性病的美国老年人药物可及性的努力不仅需要解决保险覆盖问题,还需要解决与社会经济地位和健康状况相关的障碍。
