RESUMEN
BACKGROUND: Multiple educational modalities have been utilized including leaflet, face-to-face counseling and watching videos in waiting areas for engaging patients. Considering the two challenges of waiting time frustration and lack of health screening awareness, Family Physicians' waiting area are an ideal place to bridge this gap. The objective of this study is to evaluate the effectiveness of video-based health education intervention in improving knowledge about health screening among patients and their families sitting in waiting area of Family Medicine clinics. METHODS: It was a pre and post quasi-experimental study that was conducted in family medicine clinics located at main campus and Outreach centers of a tertiary care hospital. A total of 300 participants were approached during the six month period. The intervention consisted of an educational video on health screening. The content of the video was taken from the recommended preventive care guidelines from CDC and USPSTF. The pre-and post-intervention knowledge of the participants was assessed through a semi-structured coded questionnaire by an interviewer who was trained in data collection. Data was analyzed using SPSS version 26. Pre and post intervention knowledge adequacy was determined using MacNemar's Chi-square test. RESULTS: Total 300 participants voluntarily participated into the study. Median age of the participants was 28 (IQR = 23.25-36.75) years. Majority of participants were males (56%). Following the intervention, there was significant increase in the proportion of participants (51.3% versus 68%) who had understanding of health screening check-up (p < 0.001). Following the study intervention, there was significant increase in proportion of participants who had adequate knowledge related to diabetes (p = 0.045), hypertension (p < 0.001), cholesterol (p < 0.001), cervical cancer (p < 0.001), colon cancer (p < 0.001) and hepatitis B & C (p < 0.001). No significant improvement in breast cancer related knowledge was observed (p = 0.074). Highest post-intervention increase in knowledge from baseline was observed for hypertension (13.3% versus 63.3%) followed by colon cancer (24.3% versus 59.3%), cholesterol (67 versus 96.7%), hepatitis b & C (56.7% versus 77.3%), diabetes (29.7% versus 48%), cervical cancer (1.7% versus 19%), and breast cancer (7.7% versus 18.3%). CONCLUSION: This study highlighted a pivotal role of an educational video intervention in clinic waiting area to improve awareness regarding health screening among patients and their families. Further interventional community based or multicenter studies are warranted to assess the long-term impact of these educational videos on knowledge and utilization of health screening among adult population.
