Effect of Educational Video in the Level of Knowledge of Herbal Supplements Among Patients

Patient education plays a vital role in promoting health literacy, treatment adherence, and overall wellness. Traditional methods, such as verbal instructions or printed materials, are often limited by literacy levels, comprehension barriers, and time constraints in clinical settings. With the growing accessibility of multimedia tools, this study explores the effects of educational videos in enhancing patient’s level of knowledge.
This quasi-experimental study was conducted among selected patients to assess their understanding of specific health-related topics before and after viewing educational videos. A pre-test and post-test design was used to measure knowledge levels. The intervention involved presenting a short, informative, and professionally curated educational video tailored to the patients’ needs. Data collected were analyzed using appropriate statistical tools to determine whether there was a significant improvement in knowledge after the intervention.
The results revealed that most participants demonstrated a notable increase in their knowledge levels following exposure to the educational video. Statistical analysis confirmed a significant difference between pre-test and post-test scores, indicating that audiovisual content can serve as an effective tool for patient education.
The findings highlight the importance of adopting modern, engaging, and patient- centered educational strategies in healthcare. Educational videos offer a visual and auditory experience that enhances comprehension and information retention. This study provides valuable insight into the potential of integration of technology within pharmacy and clinical practice to improve patient outcomes. Further research is recommended to examine long- term effects, different video formats, and their applicability across diverse patient populations and medical topic.
