Abstract: Background: Delirium is a frequent complication among seniors in the emergency department (ED). This condition is often underdiagnosed by ED professionals even though it is associated with functional & cognitive decline, longer hospital length of stay, institutionalization and death. Besides, frailty is increasingly recognized as an independent predictor of adverse events in seniors and screening for frailty in EDs is now recommended. Objectives: The aim of this study was to assess if screening seniors for frailty could help identify those at risk of developing delirium during their ED stay. Methodology: This study is part of the multicenter prospective cohort MIDI-INDEED 2015- 2016 study. Patients aged ³ 65 years old, initially free of delirium were recruited after 8 hours of ED exposure & followed up to 24h after ward admission. Frailty was assessed at ED admission using the Canadian Study of Health and Aging-Clinical Frailty Scale (CSHA-CFS) which classified seniors from robust (1/7) to severely frail (7/7). Seniors with CSHA-CFS ≥ 5/7were considered frail. Their Delirium status was assessed twice daily using the Confusion Assessment Method (CAM). Results: Among the 335 participants, 70 patients were considered frail, while 265 were considered robust. The cumulative Incidence of delirium at the end of follow-up was 12%. Among the frail seniors, there were 20 (28.6%) patients with delirium, while there were 20 (7.6%) in the non-frail group. The risk of delirium during the ED stay was 3.2 times higher in frail patients then in robust ones, after adjusting for age (p<0,0001). Adjusted hazard of delirium was 2.44 times higher in frail than in robust patients(HR=2.44 [1.26-4.74] p=0.0083), suggesting that “time to delirium” was 2.44 times shorter in frail older patients than the robust ones. Conclusion: Increased frailty appears to be associated with increased incident delirium in older ED patients. Screening for frailty at emergency triage could help ED professionals identify seniors at higher risk.
