E-health Enhanced Motor-cognitive Training for AED Discharged Older Adults With Cognitive Frailty

The goal of this pilot randomized controlled trial is to explore the feasibility of e-health enhanced motor-cognitive interventions for discharged community-dwelling older adults with cognitive frailty in the emergency department and to evaluate the effectiveness of the interventions on (1) cognitive functions, (2) physical functions and (3) frailty status.

Participants in the intervention group will receive three-90-minute weekly physical and cognitive training for 12 weeks, facilitated with persuasive technology on smartphones, in addition to the usual care. The control group will receive the usual care. Researchers will explore the feasibility and compare the changes of outcomes between two groups.

Motor-cognitive training effectively reverses and prevents further deterioration of cognitive function, frailty status, and physical function in older adults with cognitive frailty. Recent systematic reviews showed that older adults with cognitive frailty are more likely to develop dementia and have falls than those with frailty alone. The current time-pressured Accident and Emergency Department (AED) setting is challenging for the practitioners to have an intervention to maintain or improve the current physical and cognitive function of these older adults with non-acute complaints and prone to further deteriorate after being discharged from AED. There is a mismatch of services in traditional emergency medicine with the demand of the elderly population. Particular intervention for these older adults is needed. Based on the systematic review and the previous literature, motor-cognitive training is an essential intervention component. Interventions in a home setting can increase flexibility and improve adherence to the intervention. However, the effect on motor-cognitive training in a home setting is unknown. This study aims to explore the feasibility of e-health enhanced motor-cognitive interventions for discharged community-dwelling older adults with cognitive frailty in the emergency department and to evaluate the effectiveness of the interventions on (1) cognitive functions, (2) physical functions and (3) frailty status.

This study is a single-blinded pilot randomised, controlled study. Subjects will be allocated to either the intervention or control group by a 1:1 ratio, where they will receive motor-cognitive training in addition to usual care or usual care only. The program will be targeted older adults aged 60 or above with cognitive frailty and discharged from AED. The intervention lasts for 12 weeks, with three 90 minutes sessions (60 minutes of physical activity and 30 minutes of cognitive training) per week. Trained emergency nurses will provide respective assessments and interventions separately. The primary outcomes are to check the feasibility, including compliance, adherence and adverse effect of the study. Intervention efficacy is the secondary outcome, including physical frailty level, physical performance, and cognitive function. Fried Frailty Index will measure frailty level, physical performance will be measured by Timed-Up-Go Test, handgrip strength, gait speed, chair stand test, arm curl test and Physical Activity Scale for the Elderly. Montreal cognitive assessment (MoCA), Fuld object-memory evaluation (FOME), trail making test (TMT) will be used to measure the cognitive functions. Secondary outcome indicators included. Data will be collected in two-time points, baseline and post-intervention Findings of the study can help in improving the actual research and providing evidence for implementing motor-cognitive training for AED-discharged older adults with cognitive frailty.
