Abstract
BACKGROUND: The knowledge level of caregivers and their support for patients can affect the self-care of patients with heart failure (HF). The present study was conducted to compare the effects of teach-back, multimedia, and blended training methods on self-care and social support in patients with HF and on knowledge in their caregivers. MATERIALS AND METHODS: In a randomized clinical trial, a total of 150 HF patient-caregiver dyads were randomly allocated into three equally sized training groups, using a simple number table (n = 50). The study was conducted between May to October 2018 in Sari, northern Iran. In the teach-back, multimedia and blended training groups, patient-caregiver dyads participated in 20-30-min training sessions held face-to-face, using digital video disc (DVD) and combination of teach-back and DVD on 4 consecutive days at the bedside of hospitalized patients in coronary care unit, respectively. Data were collected using the European Heart Failure Self-Care Behaviour Scale and the multidimensional scale of perceived social support for patients. Caregivers' level of knowledge was measured using the HF Knowledge Scale. Data were measured on the first day of hospitalization, 1 day before discharge and 4 and 8 weeks after patients' discharge. Data were analyzed using SPSS version 18 (SPSS Inc., Chicago, IL, USA). RESULTS: All three educational methods improved self-care behaviors in patients. The comparison of self-care behavior scores in patients with HF among the three groups at different time points showed no statistically significant differences (P > 0.05), except 1 day before discharge (P = 0.04). There were no statistically-significant differences between the teach-back, multimedia and the blended training group in terms of perceived social support at any of the four-time points (P > 0.05). All three training methods improved the level of knowledge of caregivers. However, the score in the blended training groups was higher than the other groups (P < 0.001). CONCLUSION: According to the results of the present study, it seems that all three educational interventions can improve self-care behaviors in HF patients and increase knowledge in their caregivers. However, using the blended training method was associated with better outcomes.
