Abstract

Background: Hemophilia is a rare hereditary bleeding disorder that may lead to serious complications, especially in school settings. Teachers lack of awareness about hemophilia can endanger affected children during injuries. Structured educational interventions are considered effective in improving knowledge and emergency preparedness.
Objective: To assess the effectiveness of a structured educational intervention in increasing teachers knowledge about hemophilia.
Methods: A quasi-experimental one-group pretest-posttest design involved 42 teachers from kindergarten and elementary schools affiliated with Universitas Muhammadiyah Purwokerto. Participants were selected through purposive sampling based on specific inclusion criteria. The intervention was delivered through a 20-minute PowerPoint presentation. Teachers knowledge was measured using a 15-item questionnaire before and after the intervention. Data were analyzed using the Wilcoxon Signed-Rank Test in JASP version 0.18.3.0.
Results: A significant improvement in knowledge scores was observed after the intervention, with the median increasing from 8.0 (pretest) to 14.5 (posttest) (p < 0.001).
Conclusion: Structured educational intervention significantly improved teachers knowledge of hemophilia. Similar initiatives are recommended to enhance school preparedness in handling hemophilia-related emergencies.
