After the confirmation via the ethics group of Tehran University of Medical Sciences, subjects were chosen though utility sampling, and after obtaining a written informed consent to take part in the research, participants were set into two groups of 5 people based on random block method. In this study, assuming P = 0.5 and the confidence interval of 95%, the total number of samples was 80, and considering the loss, there were 45 people calculated for each group. In the intervention group, one patient was excluded from the study due to the unwillingness to continue participating in the study, and four patients due to defects in their questionnaire. In the control group, five patients avoided completing the survey after two months and were therefore excluded from the comprehensive study. In addition, at the end of the survey, the total number of the participants who completed the questionnaire for each group was 40 people. During discharge, after the regular training of the medical staff, both groups completed the questionnaires mentioned above. In the intervention group, in addition to the regular training received from the medical staff, one educational CD with audio and video features created by the researcher was given to the patients for use at home. The content of the CD contained an introduction to tracheostomy care, showing the daily care the tracheostomy patients need including bathing, shaving, suction, replacing the bandage around tracheostomy, cleaning the tracheostomy tube, the tracheostomy site infection symptoms, how to communicate with others and the way they should present in public. The scientific confirmation of the content of the film was given by ten professors from Tehran University of Medical Sciences. The intervention group could watch the movie with no restrictions regarding the number of times at home. To ensure that it was watched by the patients, two telephone numbers reminded them of this issue. In addition, all the patients mentioned that they watched the video. What should also be mentioned is that there were no restrictions for other members of the family regarding the watching of the movie. After two months, the patients were coordinated by the two groups to have another meeting to complete the questionnaire.
