RESUMO
OBJECTIVES: To evaluate limited English proficiency (LEP) Latino caregiver asthma knowledge after exposure to an educational video designed for this target group. METHODS: A cross-sectional, interventional study was performed. We aimed to evaluate the post-test impact on asthma knowledge from baseline after exposure to a patient-centered, evidence-based, and professionally produced Spanish asthma educational video. Participants included LEP Latino caregivers of children 2-12 years old with persistent asthma. Enrollment was performed during ED encounters or scheduled through a local community organization. Asthma knowledge was measured with a validated Spanish parental asthma knowledge questionnaire. Differences in mean scores were calculated with a paired t-test. RESULTS: Twenty caregivers were enrolled. Participants included mothers (100%) from Puerto Rico (75%), with a high-school diploma or higher (85%), with no written asthma action plan (65%), whose child's asthma diagnosis was present for at least 3 years (80%). Mean baseline asthma knowledge scores improved 8 points from 58.4 to 66.4 after watching the educational video (95% CI 5.3-10.7; t(19) = 6.21, p < 0.01). Knowledge improvements were similar across the ED and community groups. Knowledge gains were observed in the areas of ED utilization, medication usage, and activity limitations. CONCLUSIONS: The developed educational video improved caregiver asthma knowledge for a Latino population facing communication barriers to quality asthma care. Dissemination of this educational resource to LEP caregivers has the potential to improve pediatric asthma care in the United States.
