Knowledge about Chagas Disease among Family and Community Medicine Residents in a Non-Endemic Region: A Cross-Sectional Study

Abstract

ABSTRACT. Chagas disease (CD) is a parasitic disease endemic to continental Latin America that has globalized in recent years. The most relevant mechanisms of transmission of CD in non-endemic countries are transfusion with infected blood and mother-to-child transmission. There is limited information regarding practicing physicians’ knowledge of CD transmission, clinical presentation, and treatment in non-endemic countries, including Spain. Our objective was to analyze the level of knowledge about CD in family and community medicine residents and how it has evolved over the last 5 years. A cross-sectional study was performed in the framework of the training program for family and community medicine specialists in Alicante, Spain. Convenience sampling was used to enroll 214 fourth-year family and community medicine residents from 2016 to 2020. Participants completed the validated Chagas Level of Knowledge Scale questionnaire prior to attending the seminar “Health Care for the Immigrant Population.” The mean score on the scale was 7.1/10 points. Only 12 participants (5.6%) answered all questions correctly. Resident physicians who reported having received prior information on CD scored better than those who were not informed (mean, 7.2 versus 6.1 points). Participants from Latin America had scores similar to those of the rest of the participants. Over the 5-year study period, questionnaire scores tended to increase. Knowledge about CD among family and community medicine residents has improved in recent years, although it is still not optimal. Specific training on CD during specialized health care training is warranted.
