The Jintronix technology to prevent functional decline in pre-frail/frail seniors consulting Emergency Departments

Screening and identification of seniors at risk is crucial in emergency departments (EDs) in order for effective interventions to be implemented. Therefore, this project will measure the feasibility and effectiveness of a screening-intervention process in two Québec EDs.

Possible Research Results

Anticipated findingsAnticipated findings include an increase ≥ 2/12 points on the SPPB 12 weeks after the intervention (3 months post-injury), and a 30% improvement in frailty status is possible.

Impact of findingsWith a growing senior population in EDs, changes are needed to organize care accordingly. EDs must develop better tools to reduce preventable ED visits and thereby lower the associated health care costs. This innovative interdisciplinary study will be the first to implement frailty-based screening tools in the EDs for this population and to quickly direct patients to evidence based physical activity interventions accordingly. The Jintronix platform, JRS, allows the clinician to conveniently assign new exercises and monitor progress anytime and anywhere. By using JRS and the individualized physical activity program at home, prefrail and frail seniors can now feel they are getting the attention they need to maintain their independence.

About the Project

Each year in Canada, nearly 400,000 community-dwelling seniors sustain injuries that are not fatal but that limit their mobility and activities of daily living. The vast majority of them seek medical care in EDs and two thirds are discharged back home with various minor injuries. The Canadian Emergency Team Initiative has recently shown that these minor injuries can trigger a downward spiral of functional decline in seniors who are still independent at the time of injury. Moreover, these injuries may mask undetected early signs of physical impairments as well as a pre-frail or frail status. As there are no ED management guidelines for these pre-frail or frail injured seniors, their mobility and functional status deteriorate within six months post-discharge.

The main objective of this study is to implement frailty-based tools in EDs to screen seniors at risk of post-injury functional decline and to link them, at the time of consultation, to post-ED community-based mobility retraining interventions or to newly designed home-based rehabilitation technology.
