This study evaluated the impact of an infographic on patient recall of health information during a medical service trip. During two service trips in May 2018 and May 2019, patients with a history of high blood pressure from an underserved community in the Dominican Republic received an anonymous four-question pre assessment evaluating their knowledge of high blood pressure prevention and treatment. The provider then educated the patients about high blood pressure prevention and treatment using an infographic. The patients received an identical post-assessment. The median total scores for 2018 and 2019 were 75% on the pre-assessment versus 87.5% on the post-assessment (p = 0.021). The study suggests infographics may increase recall of health information for patients on medical service trips and lays the foundation for more studies using educational tools to teach patients with language, cultural, and health literacy barriers.
