Abstract

Introduction: Frailty is associated with functional decline and physiological impairments in seniors with minor injuries. Serum biomarkers have also been suggested as potential markers of these impairments in clinical studies. However, no study has addressed the usefulness of serum biomarkers among pre-frail seniors consulting emergency departments (ED) in order to detect these impairments.Objectives: The purpose of the present study was to explore the association between several serum biomarkers and the frailty status of seniors seen in ED for a minor injury who are at risk of functional decline and 2) assist professionals in clinical decisions while identifying frail seniors in whom interventions should be started in order to prevent potential functional decline. Methods: This cross-sectional study includes 190 seniors retrieved from the larger CETI cohort and discharged home from 4 EDs after treatment of minor injuries. Their frailty status was measured by the Canadian Study of Health & Aging-Clinical Frailty Scale (CSHA-CFS). Then, patients were classified as “Robust” (CHSA-CFS levels 1 and 2) vs. “Pre-frail/Frail” (CHSA-CFS levels ≥3). Biomarkers (Albumin, Creatinine, C-reactive protein (CRP), Vitamin D, Ferritin, Glucose and Insulin-Growth Factor (IGF-1)) were obtained from blood samples. “Normal” vs. “Impaired” (low and/or high) clinical threshold values were used for statistical analyses. Results: The proportion of patients with clinically high creatinine levels (>105 µmol/L for male and >85 µmol/L for female) was higher in Pre-frails/Frails when compared to Robusts (P-value=0.01). Also, regarding IGF-1, we observed that the proportion of patients with lower IGF-1 levels (<50 µg/L) was higher in patients showing Pre-frail/Frail status (P-value=0.01). Finally, a significant correlation was found between frailty status and blood glucose (r=0.22; P-value=0.02) whereas a tendency was noted for CRP level (r=0.14; P-value=0.1). Conclusion: When compared to Robust seniors, Pre-frail/Frail individuals presenting to EDs tend to have physiological dysregulations that may help detect pre-frail status in community-dwellers. Larger prospective studies are needed to specify the usefulness and clinical implications of frailty biomarkers in the continuum of acute elder care.
