P115: Limiting functional decline in seniors evaluated for minor injuries in the ED

Introduction: In its prospective cohorts of independent seniors with minor injuries, the CETIe (Canadian Emergency Team Initiative) has shown that minor injuries trigger a spiral of mobility and functional decline in 18% of those seniors up to 6 months post-injury. Because of their effects on multiple physiological systems, multicomponent mobility interventions with physical exercises are among the best methods to limit frailty and improve mobility & function in seniors. Methods: Pilot clinical trial among 4 groups of seniors, discharged home post-ED consultation for minor injuries. Interventions: 2x 1 hour /week/12 weeks with muscle strengthening, functional and balance exercises under kinesiology supervision either at home (Jintronix tele-rehabilitation platform) or at community-based programs (YWCA, PIED) vs usual ED-discharge (CONTROL). Measures: Functional Status in ADLs (Older American Ressources Scale); Global physical & social functioning (SF-12 questionnaire), physical activity level (RAPA questionnaire) at initial ED visit and at 3 months. Results: 135 seniors were included (Controls: n=50; PIED: n=28; Jintronix: n=27; YWCA: n=18). Mean age was 72.6±6.2 years, 45% were prefrail, 86% and 8% had a fall or motor vehicle-related injuries (e.g. fractures: 30%; contusions: 37%). Intervention could start as early as 7 days post-injury. Seniors in interventions (Home, YWCA or PIED) maintained or improved their functional status (84% vs 60%, p≤0.05), their physical (73% vs 59%, p=0.05) and social (45% vs 23%, p≤0.05) functioning. While 21% of CONTROLs improved their physical activity level three months post-injury, 46% of seniors in intervention did (p≤0.05). Conclusion: Exercises-based interventions can help improve seniors’ function and mobility after a minor injury.
