ABSTRACT

Background: Several authors have evaluated the relation between functional variables and prolonged stay in elderly patients with heart failure (HF). They have concluded that the functional status at admission is a strong predictor of in-hospital stay.
Objective: To identify factors of clinical and biological risk associated with prolonged stay, after an initial assessment in patients older than 65 with HF admitted to the internal medicine service.
Material and Methods: Cross-sectional, descriptive, observational study. The sample size was 53 subjects. For statistical analysis, the statistical package R version 3.0.1, together with Rcmndr virtual libraries, vcd, rgl, MASS lmtest and used. The specific objectives were to determine the statistical significance of atrial fibrillation, the day of admission, smoking, functional class according to the NYHA classification, functional dependency status with the Barthel Index (BI).
Results: HF patients remained in-hospital 4.27 days. Patients with HF and atrial fibrillation remained 2.24 days longer in-hospital. NYHA functional class III or IV grade remained around 3.19 and 2.72 days longer in-hospital, respectively.
Conclusions: patients with HF and atrial fibrillation are estimated to remain 8 days in hospital. It is determined that hypertension and smoking are not statistically significant; moderate score is associated with increased BI extended stay.
