The presence of geriatric elements, such as cognitive impairment (OR 0.75; 95% CI 0.51-1.09) and frailty, was not significantly associated with oral anticoagulant prescribing in older AF patients.

Do geriatric impairments affect oral anticoagulant prescribing in older patients with atrial fibrillation?
Despite high prevalence of geriatric impairments like cognitive impairment and frailty, these factors did not significantly influence oral anticoagulant prescribing rates in older patients with atrial fibrillation.
Effect estimate: OR 0.75 (95% CI 0.51-1.09)
OBJECTIVES: Oral anticoagulants are the cornerstone of stroke prevention in high-risk patients with atrial fibrillation (AF). Geriatric elements, such as cognitive impairment and frailty, commonly occur in these patients and are often cited as reasons for not prescribing oral anticoagulants. We sought to systematically assess geriatric impairments in patients with AF and determine whether they were associated with oral anticoagulant prescribing. DESIGN: Cross-sectional analysis of baseline data from the ongoing Systematic Assessment of Geriatric Elements in Atrial Fibrillation (SAGE-AF) prospective cohort study. SETTING: Multicenter study with site locations in Massachusetts and Georgia that recruited participants from cardiology, electrophysiology, and primary care clinics from 2016 to 2018. PARTICIPANTS: -VASc (congestive heart failure; hypertension; aged ≥75 y doubled; diabetes mellitus; prior stroke, transient ischemic attack, or thromboembolism doubled; vascular disease; age 65-74; female sex) score of 2 or higher, and no oral anticoagulant contraindications (n = 1244). MEASUREMENTS: A six-component geriatric assessment included validated measures of frailty, cognitive function, social support, depressive symptoms, vision, and hearing. Oral anticoagulant use was abstracted from the medical record. RESULTS: A total of 1244 participants (mean age = 76 y; 49% female; 85% white) were enrolled; 42% were cognitively impaired, 14% frail, 53% pre-frail, 12% socially isolated, and 29% had depressive symptoms. Oral anticoagulants were prescribed to 86% of the cohort. Oral anticoagulant prescribing did not vary according to any of the geriatric elements (adjusted odds ratios ORs for oral anticoagulant prescribing and cognitive impairment: OR = .75; 95% confidence interval CI = .51-1.09; frail OR = .69; 95% CI = .35-1.36; social isolation OR = .90; 95% CI = .52-1.54; depression OR = .79; 95% CI = .49-1.27; visual impairment OR = .98; 95% CI = .65-1.48; and hearing impairment OR = 1.05; 95% CI = .71-1.54). CONCLUSION: Geriatric impairments, particularly cognitive impairment and frailty, were common in our cohort, but treatment with oral anticoagulants did not differ by impairment status. These geriatric impairments are commonly cited as reasons for not prescribing oral anticoagulants, suggesting that prescribers may either be unaware or deliberately ignoring the presence of these factors in clinical settings.

Saczynski et al. (Tue,) conducted a cross-sectional in Atrial Fibrillation (n=1,244). Geriatric elements (e.g., cognitive impairment, frailty) vs. Absence of geriatric elements was evaluated on Oral anticoagulant prescribing (OR 0.75, 95% CI 0.51-1.09). The presence of geriatric elements, such as cognitive impairment (OR 0.75; 95% CI 0.51-1.09) and frailty, was not significantly associated with oral anticoagulant prescribing in older AF patients.
