تاثیر پخش پیام‌های سلامت بر آگاهی، میزان رضایتمندی و اضطراب همراهان بیماران مراجعه‌کننده به بیمارستان مرکز قلب تهران

Background and Objectives: One of the most important concerns of health care professionals is information.  This study was conducted with the aim of investigating the effects of health-message broadcast via the closed-circuit television (CCTV) system of the waiting lounge of Tehran Heart Center (THC) on knowledge, satisfaction, and anxiety of patients. Materials and Methods: In  this  quasi-experimental  study,  196  patients’  companions  were  selected  by the  available  sampling  method  in  2017.  The intervention tool was a 17-minute video about cardiovascular disease displayed at a certain time in the THC waiting lounge. The data were collected by the Spielberger’s State-Trait Anxiety Inventory before and after the intervention and a researcher-made questionnaire on the levels of satisfaction and knowledge after the health-message broadcast. The data were analyzed by the SPSS 22 software, using paired t-test and Pearson correlation coefficient. Results: There was a positive and significant correlation between the knowledge (r=0.480) and satisfaction (r=0.375) of individuals from health messages and the quality of the content of health messages (p=0.001). There was a significant difference between the mean scores of participants' anxiety before  and  after  intervention  (p<0.001),  indicating  the  effect of  intervention  on  reducing  their  anxiety levels. Conclusion: The  strategy  of  broadcasting  health  messages  on  the  CCTV  of  the THC waiting lounge is effective in improving the levels of knowledge, satisfaction, and anxiety of the patients’ companions and can be of help in protecting and making them participate in patient care and even prevention.
