Valoración geriátrica y factores asociados a mortalidad en ancianos con insuficiencia cardíaca ingresados en una unidad de geriatría de agudos

Abstract

Introduction and objectivesHeart failure (HF) is very prevalent in older adults, and is associated with a high mortality. The prediction of the outcome of HF and the identification of patients in advanced stages is difficult. The present work aims at identifying variables of the geriatric assessment and other clinical variables associated with an increased risk of death at one year in older adults with HF. Material and methodsProspective study of 101patients (mean age, 85.9±6.3years, 81% women) admitted during 2006 to an Acute Geriatric Unit, with principal diagnosis of HF. We recorded: demographic data, predisposing heart disease, main trigger of exacerbation, comorbidity, number of prescriptions at discharge and specific treatment of HF, average length-of-stay, readmissions, and mortality at one year after discharge. Geriatric assessment included: disability in basic (Barthel index) and instrumental (Lawton index) activities of daily living, cognitive function (Pfeiffer test), comorbidity (Charlson index), and geriatric syndromes. ResultsIn a multivariable logistic regression model, previous disability (lower Barthel index) (OR [95%CI]=1.03 [1.01-1.06]; P=.040) and higher number of re-admissions (OR [95%CI]=3.53 [1.19-10.44]; P=.023) were associated with 1-year mortality. Female sex had a protective effect (OR [95%CI]=0.15 [0.04-0.59]; P=.007). ConclusionsDisability in the basic activities of daily living and re-admissions were associated with increased 1-year mortality in older adults, whereas female sex was protective. If confirmed in further studies, these data could reinforce the need for a systematic comprehensive geriatric assessment in older adults with HF.
