DESCRIPTION (provided by the applicant): The objective of this study is to test the effectiveness of an evidence-based, Spanish language prescription drug (Rx) labeling strategy to improve patient understanding and use. The primary aims of this study are to: 1) Test the efficacy of enhanced Spanish Rx labeling (container label, leaflet) to improve Spanish-speaking patients' understanding of instructions compared to two current standard labeling strategies, and 2) Evaluate the effectiveness of the enhanced Rx labeling to improve Spanish-speaking patients' understanding and actual use of their own medicine compared to a current labeling standard. Research activities will be conducted in three phases: i) Preparation, ii) Comprehension Testing, and iii) "Actual Use" Assessment. During a brief Preparation phase, an evidence-based Spanish language Rx container label prototype and accompanying 'enhanced print' leaflets will be refined and pilot tested among Spanish-speaking adults recruited from three diverse settings. In the Comprehension Testing phase, Spanish-speaking patients' ability to comprehend the instructions for use on the enhanced Rx labeling will be compared against two standard labeling practices representing current pharmacy practices. For Aim 2, the proposed research study takes advantage of a rare opportunity within a pharmacy practice to evaluate the effectiveness of this evidence-based, Spanish Rx labeling strategy in actual use. A randomized trial will be conducted among diabetic Spanish-speaking patients at safety-net clinics affiliated with a central-fill pharmacy. Correct understanding and self-reported adherence (3-month follow-up) will be compared between Spanish-speaking patients who receive the enhanced Rx labeling and those receiving current standard labeling for all of their prescribed medicines. Pharmacy and medical records data will be used in exploratory analyses to examine label differences in adherence (refill), health care use, and outcome (HBA1C) at one year. We will also conduct a 'post-use' formative assessment of patients' perspectives regarding the clarity and utility of enhanced Rx labeling, and gather patient data pertaining to specific cultural factors to examine the association between health beliefs and practices on medication understanding and use. Findings gathered will inform anticipated next steps for a dissemination strategy.

描述（由申请人提供）：本研究的目的是测试以证据为基础的西班牙语处方药（Rx）标签策略的有效性，以提高患者的理解和使用。本研究的主要目的是：1)测试增强的西班牙语Rx标签（容器标签，传单）与目前两种标准标签策略相比，对提高西班牙语患者对说明书的理解的有效性；2)评估增强的Rx标签与目前的标签标准相比，对提高西班牙语患者对自己药物的理解和实际使用的有效性。研究活动将分三个阶段进行：i)准备，ii)理解测试和iii)“实际使用”评估。在短暂的准备阶段，一个基于证据的西班牙语Rx容器标签原型和随附的“增强印刷”传单将被完善，并在三个不同环境中招募的讲西班牙语的成年人中进行试点测试。在理解测试阶段，讲西班牙语的患者理解增强Rx标签上使用说明的能力将与代表当前药房实践的两种标准标签实践进行比较。对于目标2，拟议的研究利用药房实践中的难得机会来评估这种以证据为基础的西班牙Rx标签策略在实际使用中的有效性。一项随机试验将在中心药房附属的安全网诊所的西班牙语糖尿病患者中进行。正确理解和自我报告的依从性（3个月的随访）将比较接受增强Rx标签的西班牙语患者和接受当前标准标签的所有处方药的患者。药房和医疗记录数据将用于探索性分析，以检查一年内依从性（补充）、医疗保健使用和结果（HBA1C）的标签差异。我们还将对患者关于增强Rx标签的清晰度和效用的观点进行“使用后”形成性评估，并收集与特定文化因素有关的患者数据，以检查健康信念与药物理解和使用实践之间的关系。收集到的调查结果将为传播战略的预期后续步骤提供信息。
