Abstract

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.
