AimsDEPPAS ("Dispositivo Electrónico Personal y Portable en Salud" or Personal, Portable Electronic Health Device in English) is a portable device in form of a bracelet that allows storing electronic health records of older adults experiencing chronic illnesses. The device seeks to support the vital sustainability of older adults by storing critical health information when electronic or paper records have been lost as a consequence of a disaster. Older adults are particularly vulnerable to experience negative consequences in this context. The present study explores the end-user acceptability of DEPPAS in order to inform the next design stages of the device.MethodsTwenty home-dwelling urban male and female older adults enrolled in a chronic health management program were invited to participate in two focus groups. A prototype of DEPPAS was presented and reactions to health service disruption scenarios were explored. Focus groups were transcribed. Content analysis based on the Technology Acceptance Model was conducted.ResultsOlder adults are acutely aware of their vulnerable health status. Participants report overall positive reactions to DEPPAS. The device was associated with feelings of relief and an increased sense of control over their health management. DEPPAS is perceived as useful, usable, and safe. Even though concerns regarding confidentiality were raised, benefits are perceived as more relevant than potential risks. Participants agree that its usefulness could be extended beyond disaster situations to everyday health care management. Implications for future development and limitations are discussed.ConclusionThe conceptual design DEPPAS shows a high level of acceptability by this end user and a high potential to be integrated with other complementary technologies (e.g. GPS, medication reminders) that could significantly contribute to improving health management in disaster situations.© 2019 Hein Willius et al.
