Effect of video education on knowledge and satisfaction of patients undergoing coronary angiography

Most of patients that refer for angiography do not have enough information about the procedure; this lack of knowledge makes the patients dissatisfied. Accordingly the aim of this study was investigating the effect of video education based on patients’ native language on knowledge and satisfaction of patients hospitalized for coronary angiography. In This quasi experimental study, 160 patients were randomly assigned into two control (n=80) and experimental (n=80) groups. These patients were selected among all the patients who came for non-emergency coronary angiography for the first time in the Thoracic Department of Medical-Educational Center of Imam Khomeini in 2013. For the experimental group, an educational film about the coronary angiography was presented. And for the control group, the routine actions of the ward were presented. The awareness level of the patients in both groups was measured after and before education by using a researcher-made awareness questionnaire. And the satisfaction level of the patients in both groups was measured after education by using a researcher-made satisfaction questionnaire. Data was analyzed by SPSS13 software with using chi-square test, independent t-test and paired t-test. After the intervention, the mean of satisfaction in the experimental and control groups was respectively; 41.20 and 23.95 and the mean of awareness was respectively; 15.81 and 6.81; the experimental group in both dimensions (p =0. 001) was better than the control group. Results of this study confirm the efficiency of video education based on patients’ native language in increasing knowledge and satisfaction of the patients candidate for coronary angiography. Therefore, the video education is recommended for educating these patients.
