Delirium is a frequent preventable complication of hospitalization in elderly patients. We aimed to assess the impact of delirium on clinical and functional outcomes in older patients with an acute cardiac disease.
We analyzed 203 patients over 75 years admitted to the cardiology unit. Delirium was diagnosed based on the Confusion Assessment Method. Risk factors, comorbidity, prior geriatric conditions, diagnosis on admission, and interventions during hospitalization were recorded. Clinical (mortality, readmission) and functional outcomes (functional decline, need for new social help) were evaluated by a multivariate logistic regression analysis with a follow-up of 12 months.
The incidence of delirium was 17.2%. Patients with delirium were older (83 ± 5 vs 81 ± 5 years, p = 0.016) and had a higher incidence of major geriatric syndromes (82.9% vs 54.5%, p = 0.002). Delirium was associated with a higher length of stay (8.9 ± 6.2 vs 6.5 ± 4.0, p = 0.016) and an increased risk of functional decline at discharge (OR = 2.94, 95% CI: 1.10-7.86, p = 0.032) and long-term mortality (12-month follow-up OR = 4.20, 95% CI: 1.81-9.74, p = 0.001) after adjusting for age, comorbidity, major geriatric syndromes and diagnosis on admission (figure).
Delirium is a common complication in older patients hospitalized for an acute cardiac disease, and is related to poorer in-hospital functional and clinical outcomes, and higher long-term mortality.
