DESCRIPTION (provided by applicant): The elderly account for 1/3rd of prescription drug consumption in the United States and are at greater risk for medication errors (MEs) and adverse drug events (ADEs). They are also more likely to have low health literacy that increases the possibility of medication-related problems. Data on MEs and ADEs are collected predominantly in hospitals where it is easier to monitor such errors and to identify patients experiencing medication-related problems. This approach is not optimal in the United States, because here most medications are prescribed in the outpatient setting by primary care physicians. The proposed study will describe the spectrum of MEs and ADEs in the elderly and how health literacy affects medication safety. The aim of this application is to determine the frequency, type, severity, and preventability of MEs among elderly primary care patients who have low (inadequate and marginal) functional health literacy (FHL) vs. elderly primary care patients who have adequate FHL. Furthermore, we will conduct cognitive interviews to understand why MEs may have occurred. The study will be conducted in a primary care research network, the Southern Primary care Urban Research Network (SPUR-NetSM), which is located in Houston, Texas. In this application, we propose to evaluate medications used by 300 elderly patients from diverse ethnic and socioeconomic backgrounds who are seen by primary care providers in outpatient clinics. This is a unique study, because our main outcome measure is ME as it occurs in primary care clinics;. Moreover, we will generate findings and compare types and rates of MEs and ADEs among elderly patients who have different ethnicity, socioeconomic status, and literacy. Findings from this study will be used to design interventions for medication-safety-promotion education programs to be implemented and evaluated within primary care clinics. The proposed research is innovative, because it will provide an understanding of MEs and ADEs in a diverse primary care population and the association of health literacy with such errors. The outcomes of the proposed research will be significant, because millions of the American elderly will receive improved quality of care.

描述（由申请人提供）：老年人占美国处方药消费量的1/3，并且用药错误（MEs）和药物不良事件（ADEs）的风险更大。他们也更有可能缺乏健康知识，这增加了与药物有关的问题的可能性。关于MEs和ADEs的数据主要是在医院收集的，在那里更容易监测此类错误并确定遇到药物相关问题的患者。这种方法在美国并不理想，因为这里的大多数药物都是由初级保健医生在门诊开的。该研究将描述老年人MEs和ADEs的频谱，以及健康素养如何影响药物安全。本应用程序的目的是确定低（不充分和边缘）功能健康素养（FHL）的老年初级保健患者与具有足够功能健康素养的老年初级保健患者之间MEs的频率、类型、严重程度和可预防性。此外，我们将进行认知访谈，以了解为什么会发生小微。这项研究将在一个初级保健研究网络中进行，即位于德克萨斯州休斯顿的南部初级保健城市研究网络（spr - netsm）。在这个应用程序中，我们建议评估300名来自不同种族和社会经济背景的老年患者在门诊就诊的初级保健提供者所使用的药物。这是一项独特的研究，因为我们的主要结果测量是在初级保健诊所发生的ME；此外，我们将得出结果，并比较不同种族、社会经济地位和文化程度的老年患者的MEs和ADEs的类型和发生率。本研究的结果将用于设计在初级保健诊所实施和评估的药物安全促进教育计划的干预措施。拟议的研究具有创新性，因为它将提供对不同初级保健人群中的MEs和ADEs的理解，以及健康素养与此类错误的关联。拟议研究的结果将是重大的，因为数以百万计的美国老年人将得到更高质量的护理。
