A Quasi Experimental Study to Evaluate the Effectiveness of Audio-Visual Education on Anxiety among patients undergoing Coronary Angiography at selected hospital, Coimbatore

Abstract

Coronary angiography is the most widely used interventional and diagnostic procedure for coronary artery disease. The patient experiences the pre-procedural anxiety prior to coronary angiography. The main aim of the study was to identify the effectiveness of audio-visual education on anxiety among patients undergoing coronary angiography. Quasi experimental posttest only control group design was adopted in the study. By using Non probability purposive sampling technique 60 participants were selected and 30 were assigned to the experimental and control group respectively. The demographic variables, clinical variables were collected from the patients undergoing coronary angiography. Audio- Visual Education was provided to the patients in the experimental group for 15 minutes. Routine nursing care was provided to patients in the control group. After audio-visual education, Post-test was conducted by using the State anxiety inventory scale for both experimental and control group. It was identified that the calculated mean level of anxiety in the experimental and control group was 34.3 and 61.2 respectively with the mean difference of 26.9. Likewise the standard deviation of the experimental and control group was 10.9 and 7.9 respectively. The calculated ‘t’ value 10.79 was greater than the table value of 1.96 at 0.001 level of significance. Hence, it was concluded that Audio-visual education is an effective method in reducing the anxiety among patients undergoing coronary angiography.
