Project Summary/Abstract The proposed project relates to developing and evaluating an innovative, inexpensive, easy-to-use chair aiming to reduce the prevalence of pressure injuries among persons living with Alzheimer's disease or a related dementia (ADRD). The Agency for Healthcare Research & Quality estimates that more than 2.5 million individuals in the United States develop pressure injuries annually, resulting in treatment costs exceeding $10 billion per year. The condition is painful, often difficult to treat, and over 60,000 people die due to pressure injuries each year in the United States alone. Persons living with ADRD, both in long term care facilities and private residences, are at an increased risk for pressure injury formation due to the deterioration of several neurophysiological subsystems associated with motor, sensory, autonomic, cognitive, or behavioral pathways. Physical repositioning is the cornerstone of pressure injury prevention (and mandated by government regulation in beds); however, several barriers exist to conducting frequent, scheduled repositioning of persons living with ADRD in chairs. Some interventional technologies that have been developed for bed mattresses including reactive foam, static air, water, fiber, gel surfaces, and air‐fluidized ceramic beads along with active approaches including alternating pressure air surfaces, large‐celled ripple mattresses. Active alternating pressure air surfaces are made of air‐cells that intermittently inflate and deflate via electrically powered air compressors to regularly redistribute the pressure under the body. These mattress developments are slowly being applied to chairs. Despite the advantages of alternating pressure air surfaces, this type of surface in a chair overlay is not in ordinary widespread use due to cost, patient discomfort associated with inflation/deflation motion, compressor noise, and energy consumption. We propose an innovative low-cost chair design approach that achieves the functionality of an alternative pressure surface mattress without the need for electricity or compressed air. We hypothesize that the proposed chair will be suitable for widespread adoption both in long-term care facilities and private residences. It will be particularly useful in low-resource care environments. A prototype chair will be developed and evaluated.

项目摘要/摘要 拟议的项目与开发和评估创新，廉价，易于使用的椅子有关 降低阿尔茨海默氏病患者或相关患者的压力损伤的患病率 痴呆症（ADRD）。医疗保健研究与质量机构估计超过250万 美国的个人每年都会发生压力伤害，导致治疗费用超过10美元 每年十亿。这种情况很痛苦，通常很难治疗，超过60,000人因压力而死亡 仅在美国，每年受伤。与ADRD一起生活的人，无论是在长期护理设施中还是 私人住宅由于定义了几个 与运动，感觉，自主神经，认知或行为途径相关的神经生理子系统。 身体重新定位是预防压力伤害的基石（政府规定 床中的调节）；但是，有几个障碍存在经常进行的，预定的重新定位 与阿德德一起生活在椅子上。一些用于床床垫开发的介入技术 包括反应性泡沫，静态空气，水，纤维，凝胶表面和空气荧光陶瓷珠以及活性 方法包括改变压力空气表面，大型纹波床垫。主动替代方案 压力空气表面是由空气电池间歇性充气和放气的空气形成的 压缩机定期重新分配身体下的压力。这些床垫的开发很慢 被应用于椅子。尽管有替代压力空气表面的优势，但这种表面 由于成本，患者不适，椅子覆盖不适合使用 通货膨胀/通气运动，压缩机噪声和能耗。我们提出了一种创新的低成本 椅子设计方法可以实现替代压力表面床垫的功能 需要电或压缩空气。我们假设拟议的椅子适合宽度 在长期护理设施和私人住所中采用。这将在低资源中特别有用 护理环境。将开发和评估原型椅子。
