Effects of discharge education using teach-back methods in patients with heart failure: A randomized controlled trial

Heart failure is one of the most common causes of hospital readmission. Self-care is an essential but challenging task for patients with heart failure, and inadequate self-care is closely related to unplanned readmission and unnecessary health expenditure. Patient-centered education using the teach-back method emerged as a key strategy to prevent patients' adverse events by improving self-care. To evaluate the effects of discharge education using the teach-back method on self-care, self-care efficacy, symptoms of heart failure, caregiver dependency, and unplanned healthcare resource utilization among patients with heart failure. A prospective, two-arm randomized controlled trial. Four adult cardiology units at a tertiary hospital in Seoul, South Korea. A total of 100 patients diagnosed with heart failure and scheduled to be discharged to their homes. The intervention group received the HEART program® in addition to the usual discharge education by a trained nurse before discharge, while the control group received usual discharge education only. The discharge education included the definition of heart failure, medication, symptom management, diet, physical activity, and other precautions. Data on self-care (self-care maintenance; symptom-perception; self-care management), self-care efficacy, symptoms of heart failure, and caregiver dependency were measured at 7-days after discharge (T1), and unplanned healthcare resource utilization (including readmission, emergency room visit, and healthcare professional contacts) was assessed at 1-month after discharge (T2). Outcomes were analyzed with ANCOVA. A total of 94 patients (intervention group = 45, control group = 49) completed outcome measurements at the three-time points. Participants in the intervention group showed a significant improvement in self-care maintenance (F = 11.597, p = 0.001), symptom perception (F = 20.173, p < 0.001), self-care management (F = 7.205, p = 0.009), and self-care efficacy (F = 4.210, p = 0.043) compared to the control group. However, there were no statistically significant differences in symptoms of heart failure, caregiver dependency, and unplanned healthcare resource utilization between the two groups (all ps > 0.05). The findings demonstrated that discharge education using the teach-back method is an effective educational strategy to improve self-care and self-care efficacy in patients with heart failure. We recommend nurses implement discharge education using the teach-back method for patients with heart failure.
