Effectiveness of Orientation Programme on Knowledge and Anxiety among Patients Undergoing Coronary Angiography at Selected Hospital

According to WHO, (2008), Out of the 17.3 million cardio vascular deaths, heart attacks were responsible for 7.3 million deaths and strokes were responsible for 6.2 million deaths. Coronary artery disease (CAD) is the leading cause of death in the world, coronary angiography remains the gold standard for detecting clinically significant atherosclerotic CAD. The aim of the study was to evaluate the effectiveness of orientation programme on knowledge and anxiety among patients undergoing coronary angiography at selected hospital.

A pre-experimental design was adopted for a total samples of 30 patients through non-probability convenience sampling technique. A pre test was conducted using a structured interview schedule to collect information regarding demographic variables and the Speilberger's state anxiety scale was used to assess the anxiety and a semi structured questionnaire to assess the knowledge. The post test was given on the 7^th day to assess the knowledge and anxiety.

The paired ‘t ’value for knowledge was 20.26, which was significant at P<0.05 level. Hence, H₁ was retained. The obtained ‘t ’value for anxiety was 17.5, which was significant at P<0.05 level. Hence H₂ was retained. The pre test and post test V value for knowledge and anxiety was-0.223 and-0.340 respectively, showing a negative correlation between the pre test and post test scores of knowledge and anxiety among patients undergoing coronary angiography. Hence H₃ was retained at P<0.05 level. There was a significant association (² =8.44) between anxiety and sex of the patient and significant association (χ²=9.71) with patient's dietary habit at P<0.05 level. Hence H⁴ was retained for these two variables and rejected for all other variables. The study concluded that orientation programme was effective in improving the knowledge and reducing the anxiety of the patients undergoing coronary angiography.
