Tablet-based frailty assessments in emergency care for older adults

The rise in aging populations worldwide places a focus on shifting healthcare needs to match changing demographics. Older adults have a higher risk of becoming frail and losing functional abilities (e.g., walking and bathing) as well as the ability to perform daily activities such as shopping and cooking. Providing care and appropriate interventions to assist older adults with frailty is contingent upon identifying these individuals through effective screening. Frailty is often characterized by self-reports of exhaustion, weakness, slowing, and low physical activity. Older adults at risk of becoming frail often enter the healthcare system through emergency services (e.g., calling 911 or presenting at an emergency department), and screening should target these entry points. This paper discusses the design process, and usability findings associated with a tablet-based battery of frailty measures for assessing functional and cognitive states in elderly adults while being admitted to emergency care. This research is focusing on the use of digital technologies as a medium for physical and mental frailty assessment in emergency care. A diverse group of healthcare users is envisaged including paramedics, physicians, and research personnel, as well as end-users such as elderly patients and their caregivers. We describe the development and usability of the tablet-based frailty assessment system and we report on the concurrent validity of frailty measures.
