Emergency department interventions for frailty (EDIFY): improving functional outcomes in older persons at the emergency department through a multicomponent frailty intervention.

Abstract

emergency department interventions for frailty (EDIFY) delivers frailty-centric interventions at the emergency department (ED). We evaluated the effectiveness of a multicomponent frailty intervention (MFI) in improving functional outcomes among older persons. a quasi-experimental study. a 30-bed ED observation unit within a 1,700-bed acute tertiary hospital. patients aged ≥65years, categorised as Clinical Frailty Scale 4-6, and planned for discharge from the unit. we compared patients receiving the MFI versus usual-care. Data on demographics, function, frailty, sarcopenia, comorbidities and medications were gathered. Our primary outcome was functional status-Modified Barthel Index (MBI) and Lawton's iADL. Secondary outcomes include hospitalisation, ED re-attendance, mortality, frailty, sarcopenia, polypharmacy and falls. Follow-up assessments were at 3, 6 and 12months. we recruited 140 participants (mean age 79.7 ± 7.6years; 47% frail and 73.6% completed the study). Baseline characteristics between groups were comparable (each n = 70). For the intervention group, MBI scores were significantly higher at 6months (mean: 94.5 ± 11.2 versus 88.5 ± 19.5, P = 0.04), whereas Lawton's iADL scores experienced less decline (change-in-score: 0.0 ± 1.7 versus -1.1 ± 1.8, P = 0.001). Model-based analyses revealed greater odds of maintaining/improving MBI in the intervention group at 6months [odds ratio (OR) 2.51, 95% confidence interval (CI) 1.04-6.03, P = 0.04] and 12months (OR2.98, 95%CI 1.18-7.54, P = 0.02). This was similar for Lawton's iADL at 12months (OR4.01, 95%CI 1.70-9.48, P = 0.002). ED re-attendances (rate ratio 0.35, 95%CI 0.13-0.90, P = 0.03) and progression to sarcopenia (OR0.19, 95%CI 0.04-0.94, P = 0.04) were also lower at 6months. the MFI delivered to older persons at the ED can possibly improve functional outcomes and reduce ED re-attendances while attenuating sarcopenia progression.
