This study aimed to investigate the predictors of 1 year-readmission in patients with acute decompensated heart failure within a year. A retrospective study was applied with a sample of 461 eligible HF patients, who were admitted to a tertiary care hospital. Reviews of annual medical records were conducted for data collection which consisted of two domains, including demographic domain (age and gender) and heath and illness (length of stay, co-morbidity, serum creatinine, serum sodium, heart rate [HR], and systolic blood pressure [SBP]). Descriptive statistic was used to analyze frequency and percentage of demographic data and binary logistic regression was used to model the effect of predictors of 1 year-readmission after hospital discharge.
The results show that fifty-one percents of HF patients were 1 year-readmissions with ADHF. Three variables, including comorbidity, SBP, and HR variable, were significant association with 1 year- readmission. The final predictive model with binary logistic regression test was 57.3% variance explained. Increment risk for hospital readmission was found in patient with comorbidity (OR 2.83, 95%CI 1.36-5.91). Patients with HR > 80 bpm had predicted hospital readmission (OR 1.60; 95%CI 1.10- 2.33). Additionally, patients with SBP ≥ 140 mmHg had lower risk of hospital readmission by 41% (OR 0.59; 95%CI 0.37-0.91).
The findings of this study offer insight information for caring HF patients. The nurses should provide appropriately continuity of care for HF patients who were cormobidity, HR higher than 80 bpm, and SBP lower than 140 mmHg before hospital discharge.
