Background:Cardiac self-efficacy is an essential factor in persistence of healthy behaviors in patients with coronary artery disease (CAD). Today, telenursing methods have numerous applications in health care. Therefore, this study aimed to determine the effect of a text message and telephone follow-up program on cardiac self-efficacy of patients with CAD.Materials and Methods:This was a randomized controlled trial on 70 patients with CAD who were hospitalized in Shahid Chamran Hospital (Isfahan, Iran). The participants were randomly assigned to the experimental and control groups. Collection of data on cardiac self-efficacy was performed before, 3 months after, and 4 months after the beginning of the intervention using Cardiac Self-Efficacy Scale designed by Sullivan et al. During the 3 months of intervention, six messages were sent to the subjects each week and calls were made twice a week in the first month and once a week during the second and third months. The statistical analysis of data was performed using independent t-test, Chi-square, Mann-Whitney U test, and repeated measures analysis of variance (ANOVA).Results:Before the intervention, there was no significant difference between the mean scores of cardiac self-efficacy of the two groups. However, 3 months and 4 months after the beginning of the intervention, the mean score of cardiac self-efficacy in the experimental group was significantly higher than in the control group (P < 0.001).Conclusions:The text message and telephone follow-up program is effective in promoting the cardiac self-efficacy of patients with CAD.

Background: Cardiac insufficiency is one of the leading causes of mortality in the world and affects quality of life more than other chronic diseases. Cardiac self-efficacy can be considered for improving the quality of life of patients with this disease. Objectives: The purpose of this study was to determine the relationship between quality of life and cardiac self-efficacy in patients with heart failure. Methods: This descriptive correlational study was performed on 227 patients with heart failure who referred to the cardiac clinics of Isfahan University of Medical Sciences affiliated hospitals, Iran, 2016-17. Sampling was done in a simple random way. The data gathering tool was comprised of three parts: demographic data questionnaire, Sullivan cardiac self-efficacy questionnaire, and Quality of Life questionnaire. Data were analyzed by SPSS software version 22. Results:The mean score of self-efficacy was 58.45 ± 25.92 and the mean score of satisfaction and importance of quality of life was 69.73 ± 18.72 and 82.76 ± 15.46, respectively. The results of this study showed that the importance of quality of life and satisfaction with quality of life are related to cardiac self-efficacy (P < 0.001). Pearson correlation coefficients showed a direct correlation between the scores of quality of life dimensions and the score of cardiac self-efficacy (in all cases, P < 0.001). Conclusions: There is a positive and significant relationship between quality of life and cardiovascular self-efficacy in patients with heart failure.

Background: The main problem of preterm infants is lung function disorder and disordered oxygenation due to an immature respiratory tract, therefore, appropriate performance of nurses in oxygen therapy is very important. Objectives: The aim of this study was to investigate nurses' performance during oxygen therapy for hospitalized infants at the neonatal intensive care unit (NICU). Patients and Methods:In this descriptive, cross-sectional study, 110 nurses working at the NICU of teaching hospitals affiliated with the Isfahan University of Medical Sciences were enrolled by the census. Data were gathered from a questionnaire on demographic characteristics and a checklist for observational assessment of nurses' performance. Data analysis was done with the SPSS 20 software. Results: Of the nurses, 39.1% had favorable performance. Furthermore, Spearman's correlation coefficient indicated that age and nurse's performance were directly and significantly correlated, yet education level and work shift types were not correlated with performance. Conclusions: Since oxygen is frequently administered at the NICU, holding in-service training courses for improving nurse's performance and preventing long-term complications due to oxygen administration seem necessary.
