Development of a stick-on hip protector: A multiple methods study to improve hip protector design for older adults in the acute care environment

摘要

Introduction Over 90% of hip fractures in older adults result from falls, and hospital patients are at especially high risk. Specific types of wearable hip protectors have been shown to reduce hip fracture risk during a fall by up to 80%, but user compliance has averaged less than 50%. We describe the development and evaluation of a “stick-on” hip protector (secured over the hip with a skin-friendly adhesive) for older patients in acute care. Methods An initial version of the product was evaluated with six female patients (aged 76–91) in a hospital ward, who were asked to wear it for one week. We subsequently refined the product through biomechanical testing and solicited feedback from 43 health professionals on a second prototype. Results The first prototype was worn by five of six patients for the full week or duration of their hospital stay. The second prototype (20?mm thick, surface area 19?×?15.5?cm) provided 36% force attenuation, more than common garment-based models (20–21%). Feedback from patients and health professionals highlighted usability, comfort, cost, and appearance. Conclusions Our results from biomechanical and user testing support the need for further work to determine the value of stick-on hip protectors in acute care.
