Introduction: Myocardial infarction (MI) affects over 3 million individuals globally and is responsible for over 1 million deaths annually in the United States. MI results in irreversible myocardial damage due to inadequate oxygen supply, potentially impairing both diastolic and systolic functions, and increasing the risk of life-threatening arrhythmias. Prompt restoration of blood flow is critical, with treatment within six hours of symptom onset significantly improving outcomes.
Aims of the Study: The study aimed to evaluate the effectiveness of video-assisted teaching in enhancing knowledge regarding the pre-hospital management of acute myocardial infarction among bus operators in selected areas of Pune city.
Methodology: A Quantitative, Quasi Experimental Study design was adopted. A total of 120 participants were selected using a non-probability purposive sampling technique. Data were collected through a structured demographic questionnaire and analyzed using descriptive statistics.
Results: The post-test mean score was 15.23 with a standard deviation of 2.21. Demographic variables including age, gender, education, years of experience, and prior knowledge did not exhibit a statistically significant association with knowledge outcomes (p > 0.05). Notably, 76.67% of participants in the experimental group achieved excellent post-test scores, indicating a significant improvement in knowledge following the video-assisted intervention. The control group showed minimal improvement, further validating the intervention's effectiveness.
Conclusion: The study concluded that video-assisted teaching significantly enhances knowledge regarding pre-hospital management of Acute Myocardial Infarction among bus operators. The intervention’s effectiveness was independent of demographic variables, suggesting its broad applicability across diverse groups.
