Developing Community Event-Based Surveillance Technology for Disease Outbreaks in Cross-Cultural Contexts
摘要
This study addresses the development of a Community Event-Based Surveillance (CEBS) digital system, focusing on cross-cultural collaboration between community leaders in Brazil and Cape Verde, as part of the Guardians of Health—Community Leaders project. CEBS utilizes community leaders as sources for monitoring public health, emphasizing its importance in situations where resources are limited. This research investigates whether involving community leaders from different countries in adapting and developing a health surveillance application impacts the usability and acceptance of these tools and identifies cross-cultural factors that must be considered for implementation in other territories. We employed a user-centered design approach that included workshops and usability testing. Our evaluation considered two phases: Phase 1 involved testing an initial version of the application and gathering feedback for improvements, while Phase 2 assessed the revised version to compare usability metrics. Substantial advancements were highlighted in the results. User satisfaction, measured by the System Usability Scale (SUS), increased from 81.6 in Phase 1 to 84.1 in Brazil and from 76.6 to 84.2 in Cape Verde. Efficiency was improved, with average completion times reduced, decreasing from 359 to 277.6 s in Cape Verde. However, cross-cultural challenges continued: in Cape Verde, the need for offline functionality, while in Brazil, improvements on accessibility for users with different levels of digital literacy. The research reinforces the importance of cross-cultural design principles and the involvement of community leaders as co-designers to create inclusive and sustainable digital solutions for global health challenges.
