RESUMEN
Incontinence and toileting difficulties can often be successfully addressed by treating their underlying causes. However, (complete) cure is not always possible and continence products to prevent or contain unresolved leakage or to facilitate toileting are in widespread use. Many people use them successfully but identifying the product(s) most likely to meet individual needs can be challenging and the recently published Seventh International Consultation on Incontinence includes a chapter which draws on the literature to provide evidence-based recommendations to help clinicians and product users to select appropriate products. This paper is based on the same evidence, but reviewed from the different perspective of those keen to identify unmet needs and develop improved products. For each of the main continence product categories it (i) outlines the design approach and key features of what is currently available; (ii) provides a generic functional design specification; (iii) reviews how well existing products meet the requirements of their main user groups; and (iv) suggests priorities for the attention of product designers. It also flags some core scientific problems which - if successfully addressed - would likely yield benefits in multiple incontinence product contexts.
