Justification and design of the BOCADOS-IC study: nutritional management in adults followed in Spanish hospitals for heart failure

Introduction and objectives: Malnutrition is common in patients with heart failure (HF) and is associated with increased mortality and hospital admissions. There is evidence that nutritional intervention in the inpatient setting improves the prognosis, but evidence in the outpatient setting is limited. This study aims to assess whether a nutritional intervention in outpatients with HF and malnutrition produces a benefit in their morbidity and mortality.
