As part of the national Stop the Bleed campaign in the United States, more than a million people have received bleeding control training through the work of many organizations. These public and professional educational experiences are ideally grounded in health sciences, clinical, and educational evidence to be most effective. However, there is currently no standard tool for evaluating the educational quality of these programs. We developed and validated the Stop the Bleed Education Assessment Tool (SBEAT) to provide a standard measure of life-threatening bleeding educational programs knowledge learning outcomes to aid in evaluation and development of this public health program. The SBEAT development included medical, clinical, and educational experts to derive and validate learning outcomes. Specific item writing incorporated focus groups for input on language and then pilot testing before a full community pilot test established a data set, for which a Rasch methodology was applied. The resulting tool used 34 items embedded in 19 survey questions, with item separation statistic of 5.56 (0.97 reliability) and person separation statistic of 2.09 (0.81 reliability) for 171 persons. Overall, the Cronbach Alpha (KR-20) person score "test reliability" equaled 0.85 (SEM = 2.24). The SBEAT project establishes a standardized assessment tool to evaluate the cognitive aspects of first aid for life threatening bleeding. Comparison of outcomes from different teaching styles and methods will allow for the development of best practices for future bleeding control education and help organizations demonstrate value to learners, funders, and policy makers, and advance health sciences education. SBEAT offers a measure for which educational efficiency and efficacy can be judged within a larger effort to prepare people for personal emergencies or large-scale disasters.
作为美国全国“止血”运动的一部分，超过100万人通过众多组织的工作接受了出血控制培训。这些公共和专业教育体验理想地基于健康科学、临床和教育证据，以达到最佳效果。然而，目前尚无评估这些项目教育质量的标准工具。我们开发并验证了“止血教育评估工具”（SBEAT），以提供一种对危及生命出血教育项目知识学习成果的标准衡量方法，以帮助评估和发展这一公共卫生项目。SBEAT的开发包括医学、临床和教育专家，以得出并验证学习成果。具体的项目编写纳入了焦点小组以获取语言方面的意见，然后进行预测试，之后进行全面的社区预测试以建立一个数据集，并应用了拉施方法。最终的工具使用了19个调查问题中的34个项目，171人的项目区分度统计为5.56（信度为0.97），人员区分度统计为2.09（信度为0.81）。总体而言，克朗巴哈α（KR - 20）人员得分“测试信度”等于0.85（标准误 = 2.24）。SBEAT项目建立了一个标准化评估工具，以评估危及生命出血急救的认知方面。比较不同教学风格和方法的结果将有助于为未来的出血控制教育制定最佳实践，并帮助组织向学习者、资助者和政策制定者展示价值，推进健康科学教育。SBEAT提供了一种衡量方法，通过它可以在更大的努力中判断教育效率和效果，为个人紧急情况或大规模灾难做好准备。
