The high prevalence of urinary tract infection in aging adults is a challenging aspect of geriatric care. Incontinence and cognitive/functional impairment make collection of urine samples difficult and often require either catheterization for sample collection, which is a risk factor for infections, or more lenient criteria for initiating antibiotic treatment. We report the development of a diaper inlay with absorbent materials, superabsorbent polymer-based valve and chemical reaction pads for rapid screening of urinary tract infection of incontinent diaper-wearing elderly receivers of home care services. The developed diaper inlay was capable of collecting, isolating, analyzing samples and retaining results > 8 h. The diaper inlay can therefore be compatible with the diaper changing routines of nurses in home care services, without requiring much time or effort. A nurse can insert a diaper inlay in a diaper and the results can be recorded during a later diaper change. Although the research focuses on tools for home care services, the nursing home sector has similar problems and may benefit from technological development for rapid screening to avoid unnecessary catheterization and overuse of antibiotics.
老年人尿路感染的高发率是老年护理面临的一个挑战。失禁和认知/功能障碍使得尿液样本的收集变得困难，通常需要进行导尿以采集样本，这是感染的一个风险因素，或者放宽抗生素治疗的起始标准。我们报告了一种尿布衬垫的开发，该衬垫采用吸水性材料、基于高吸水性聚合物的阀门和化学反应垫，用于快速筛查失禁尿布使用者的尿路感染。开发的尿布衬垫能够收集、隔离、分析样本并保留结果>8 小时。因此，这种尿布衬垫可以与家庭护理服务护士的尿布更换常规相兼容，而不需要太多时间或精力。护士可以在尿布中插入尿布衬垫，然后在以后的尿布更换期间记录结果。虽然这项研究的重点是家庭护理服务的工具，但养老院部门也存在类似的问题，可能受益于快速筛查的技术发展，以避免不必要的导尿和抗生素的过度使用。
