A Study to Determine the Effectiveness of Video Assisted Teaching Vs Lecture Method on Knowledge of Staff nurses Regarding Immediate Management of Patients with Myocardial Infarction, at a Selected Hospital, in Visakhapatnam District
Abstract: Introduction- The Heart is having a superb mechanism, with a great wisdom in its construction. It is the central organ of the circulatory system & #039, acting as a force and suction pump in relation to the blood vessels. The integrity of the coronary arteries is an important determinant of oxygen supply to the heart muscle. Any disorder that reduces the lumen of one of the coronary arteries may cause a decreased in blood flow and oxygen delivery to the area of the myocardium supplied by that vessels and leads to acute coronary syndromes of Angina pectoris, myocardial infarction and sudden cardiac death. Worldwide 32.4 million people are suffering from cardiovascular diseases. In India 30 million suffer from cardiovascular disease Methodology-An quantitative research approach with pre-experimental one group pretest post-test design was used for the study. The subjects were 60 staff nurses selected by non- probability convenience sampling technique. Video assisted teaching and Lecture was administered after the assessment of pre-test knowledge on immediate management of patient with Myocardial infarction. Post intervention knowledge was assessed on the 7 day of the administration of Video assisted teaching and Lecture through the same structured knowledge questionnaire. Results - The study revealed that out of 60 samples pretest knowledge of staff nurses 9 (96.67 %) in video assisted teaching and 27 (90.0 %) in lecture method had moderate knowledge. Pre-test mean score was 17.766 for video assisted teaching and 17.3 for lecture method. After intervention the Knowledge level of staff nurses were increased from moderate knowledge to adequate knowledge level 29 (96.67 %) in video assisted teaching and 9 (30.0 %) in lecture method had adequate knowledge. The mean post test knowledge score of Video assisted teaching 25.4 was greater than the mean post test score of lecture 19.36, showed that there is a significant difference between the post test knowledge scores of staff nurses. The obtained t Value 10.7869 is greater than table value 2.001 at 58 DF at 0.05 level of significance. Therefore the obtained t value is found to be significant. Hence, we have sufficient evidence to conclude that video assisted teaching gives more knowledge than lecture method. The chi- square test revealed that there was no significant association between the demographic characteristic and their knowledge regarding immediate management of patient with myocardial infarction. Conclusion- This study concluded that intervention programme played an important role in enhancing the knowledge level of respondents.
