Background & Aim: Besides medical treatment, self-care education is necessary for patients with heart failure. The aim of this study is to compare the effect of telenursing and education without follow-up in the caregivers of heart failure patients on the self-care behavior and clinical status of heart failure patients.

Methods & Materials: This clinical trial (IRCT2016080829184N2) was performed on 66 heart failure patients referred to the clinic of Taleghani hospital in Abadan in 2015-2016. The patients were randomly divided into three groups: control, intervention-1 and intervention-2 groups. Control group did not receive any intervention. Patients and caregivers in the intervention-1 group received verbal education, and caregivers in the intervention-2 group received continuous phone follow-up plus verbal education. Self-care behavior, fatigue severity and exercise tolerance were assessed in the patients by the self-care behavior questionnaire, fatigue severity scale and six minutes walking test at baseline and the end of 3 months. Descriptive statistics, chi-square, paired t-test, ANOVA, ANCOVA and Scheffe post hoc test were used to analyze the data using the SPSS software v.18.

Results: At baseline, three groups were consistent in terms of demographic variables and three variables. At the post-test, there was a significant difference between the intervention-2 group with the control group and intervention-1 group in self-care behavior (P<0.001) and the patients’ fatigue score mean (P<0.004). But, no significant difference was observed between three groups in the patients’ exercise tolerance score mean.

Conclusion: Telenursing for the caregivers of heart failure patients can lead to the improvement of self-care behavior and decrease in fatigue among the patients.
