RESUMO
BACKGROUND: Asthma has a growing prevalence all over the world. GINA guidelines had improved diagnostic and therapeutic asthma approach, but it is not enough. OBJECTIVE: To evaluate the knowledge about GINA in physicians of first, second and third care level. PARTICIPANTS AND METHODS: Physicians working in first, second and third care level, from medical units related to the Centro Medico Nacional La Raza answered a 19 items questionnaire about GINA. Results were analyzed with Kruskal-Wallis, Pearson's correlation and U of Mann-Whitney tests. RESULTS: We included 179 physicians with an age average of 43 years; 99 or them were 99 females and 80 males. According to medical specialty, Allergy and Immunology had 145 points; Pneumology, 136; Pediatrics, 122; Family Medicine, 81 and Internal Medicine, 78. We found a statistical difference between these specialties (p < 0.0001). Doctors from third and second care level had a higher and significative scoring than first care level colleagues (p < 0.005). We did not find differences between labor years, working schedule and gender with GINA knowledge scoring. CONCLUSIONS: There are differences in GINA knowledge between medical specialties and care level.
