Effectiveness of Edutainment-Based Interventions in Increasing Knowledge of Rheumatic Fever and Rheumatic Heart Disease Among School-Going Children in Nepal: Study Protocol for Colors to Save Hearts Quasi-Experimental Pretest-Posttest Study

Background: Acute rheumatic fever (ARF) and its sequela, rheumatic heart disease (RHD), remain significant public health concerns in low- and middle-income countries, including Nepal. Despite their preventable nature, awareness of ARF and RHD among schoolchildren is limited. Innovative, age-appropriate health education strategies are urgently needed to promote early recognition and prevention. Objective: This study aims to evaluate the effectiveness of an edutainment-based intervention in improving knowledge of ARF and RHD among school-going children in Nepal. Methods: A quasi-experimental pretest-posttest study design with a waitlist control group will be employed across 24 public schools in six diverse districts. A total of 2,400 students from Grades 6 to 9 will be included. The intervention integrates creative educational tools-coloring books, activity books, storytelling, videos, and interactive sessions-tailored to different age groups. Knowledge change will be measured using a validated questionnaire administered at baseline and post-intervention. Secondary outcomes include the prevalence of RHD-related symptoms assessed through clinical screening. Expected Outcomes: It is hypothesized that students in the intervention group will demonstrate a statistically significant improvement in knowledge scores compared to their baseline levels and the control group. The study will also assess the feasibility and acceptability of the intervention and inform recommendations for broader school-based health education programs. Conclusion: This study addresses a critical gap in child health education in Nepal using an innovative, scalable approach. Findings will contribute to the evidence base for integrating edutainment into school curricula to combat preventable diseases like RHD in resource-limited settings.
