BackgroundThe Mexican Guidelines for the diagnosis and treatment of urticaria have been published. Just before their launch, physicians' knowledge was explored relating to key issues of the guidelines.ObjectiveThe aim of this study was to investigate the opinion of medical specialists concerning urticaria management.MethodsA SurveyMonkey® survey was sent out to board-certified physicians of three medical specialties treating urticaria. Replies were analyzed per specialty against the evidence-based recommendations.ResultsSixty-five allergists (ALLERG), 24 dermatologists (DERM), and 120 pediatricians (PED) sent their replies. As for diagnosis: ALERG 42% and PED 76% believe cutaneous mastocytosis, urticarial vasculitis, and hereditary angioedema are forms of urticaria, versus DERM 29% (P < 0.005). Most of the specialties find that the clinical history and physical examination are enough to diagnose acute urticaria, except DERM 45% (P < 0.01). DERM 45% believe laboratory-tests are necessary, as opposed to <15% ALLERG-PED (P < 0.005). However, PED 69% did not know that the most frequent cause of acute urticaria in children is infections, versus ALLERG-DERM 30% (P < 0.005). Many erroneously do laboratory testing in physical urticaria and ALLERG 51%, DERM 59%, and PED 37% do extensive laboratory testing in chronic spontaneous urticaria (CSU); many more PED 59% take Immunoglobulin G (IgG) against foods (P < 0.005). More than half of non-allergists do not know about autologous serum testing nor autoimmunity (P < 0.05). As for treatment, there were a few major gaps: when CSU was controlled, >75% prescribed antihistamines pro re nata, and >85% gave first-generation antiH1 for insomnia. Finally, >40% of DERM did not know that cyclosporine A, omalizumab, or other immunosuppressants could be used in recalcitrant cases.ConclusionSpecialty-specific continuous medical education might enhance urticaria management.
