Possible effect of video and written education on anxiety of patients undergoing coronary angiography

Purpose: The aim of this study was to investigate possible effects of video and written education on anxiety of patients undergoing coronary angiography. Design: The study design was quasi-experimental. Methods: This randomized controlled semitrial model included patients who underwent coronary angiography between October 2015 and May 2016 at the Department of Cardiology of a university hospital. The number of subjects determined by power analysis was 90 patients in three groups. Written education, video education, and control groups were included. Data were collected using personal information forms, State-Trait Anxiety Inventory, and physiological variables. Findings: There was a statistically significant difference in the mean scores of state anxiety, satisfaction, and physiological variables after education, compared with baseline, in both patient and control groups (P , .005). Conclusions: Our study results suggest that education given by the nurse before the procedure reduces level of anxiety and affects physiological variables positively
