Rationale and Design of a Novel Method to Assess the Usability of Body-Worn Absorbent Incontinence Care Products by Caregivers.

The setting was a simulated laboratory, not a real home or nursing home, and the authors say the method needs validation in different care environments. Caregivers were experienced professional nursing-home caregivers familiar with the products, so results may not apply to family caregivers or less experienced staff. Simulated patients were passive and did not receive real skin care or product changes on real patients. Only one manufacturer's product types were tested, and no other manufacturer's products were included. Analysis included only changes performed in line with intended use, and the number of caregivers varied from 25 to 34 per product-posture combination. The method was a first application, and assumptions such as independence between metrics need further testing.

The supplied text says a cross-disciplinary group recruited by the product manufacturer SCA Hygiene Products AB and testing institute RISE Research Institutes of Sweden AB helped identify usability characteristics. Facilities were provided by Scandinfo Marketing Research AB. It does not give a separate funding or conflict-of-interest declaration.

Do not read the 90% or 81% scores as proof that one product is better for patients. The study used simulated patients in a laboratory and measured caregiver product-change tasks, not real-patient clinical outcomes.
