an interactive multimedia training on anxiety, uncertainty, and hope among patients undergoing percutaneous coronary intervention: an interventional study

Background: one of the most common treatments for cardiovascular diseases is coronary angioplasty. due to the short period of hospitalization, less attention has been given to patients’ education. this study was carried out to investigate the effects of interactive multimedia (im) training on anxiety, uncertainty, and hope among percutaneous coronary intervention (pci). methods: in this interventional study, 90 eligible patients were enrolled one day before angioplasty in september-december 2019. using the block random sampling method, the patients were assigned to im training (n=45) or an educational pamphlet (n=45). anxiety, uncertainty, and hope were evaluated at three periods (before, one day, and two weeks after pci) using the depression anxiety and stress scales (dass-21), mishel uncertainty of illness scale (muis), and snider hope scale. the chi-square test, independent t-test, and repeated measurements using spss18 were used for statistical analysis. results: one week and two weeks after the intervention, the hope score was significantly improved; uncertainty and anxiety levels were reduced considerably more in the multimedia group than in the educational pamphlet (p<0.001); and repeated measurement analysis confirmed the effectiveness of im (p<0.001). conclusion: im training reduced anxiety and uncertainty and improved hope among patients. since most patients were illiterate, im training was easier and more accessible.
