The two-arm Clinical Decisions/Diagnostic Workshop (CD/DW) approach to undergraduate medical education has been successfully used in Brazil. Objective: Present the CD/DW approach to the teaching of stroke, with the results of its pre-experimental application and of a comparative study with the traditional lecture-case discussion approach. Method: Application of two questionnaires (opinion and Knowledge-Attitudes-Perceptions-KAP) to investigate the non-inferiority of the CD/DW approach. Results: The method was well accepted by teachers and students alike, the main drawback being the necessarily long time for its completion by the students, a feature that may better cater for different educational needs. The comparative test showed the CD/DW approach to lead to slightly higher cognitive acquisition as opposed to the traditional method, clearly showing its non-inferiority status. Conclusion: The CD/DW approach seems to be another option for teaching neurology in undergraduate medical education, with the bonus of respecting each learner`s time.Keywords: neurology, stroke, medical education, teaching materials.RESUMO O método Decisões Clínicas/Oficinas Diagnósticas (DC/OD) é usado com sucesso na graduação médica no Brasil. Objetivo: Apresentar o método DC/OD usando o exemplo do Acidente Vascular Encefálico, assim como os resultados de sua aplicação pré-experimental e de um estudo comparativo com o método tradicional (aula mais discussão de casos). Método: Aplicação de questionários de opiniões e de questionários de conhecimentos, atitudes e percepções para investigar a não inferioridade do método DC/OD. Resultados: DC/OD foi bem aceito por professores e estudantes. A principal crítica foi o tempo necessariamente longo para os estudantes completá-lo, característica que pode atender às diferentes necessidades educacionais. O estudo comparativo demonstrou que o método DC/OD levou a uma aquisição cognitiva maior que o tradicional, demonstrando sua não inferioridade. Conclusão: O método DC/OD parece ser uma alternativa para o ensino da neurologia na graduação médica, com a vantagem de respeitar o diferente tempo de aprendizado dos estudantes.Palavras-chave: neurologia, acidente vascular cerebral, educação médica, materiais de ensino.The last decades have witnessed a deluge of scientific evidence in all areas of neurology 1 . Yet, such evidence is still little applied to those who need it most, patients 2 , as the diagnostic acumen of primary care practitioners, chiefly in neurology, has lagged behind 3,4,5 . These professionals who lack the basic skills of data collection and interpretation, differential diagnosis and diagnostic work-up place a heavy burden on already over-stretched health systems 6,7 . Additionally, clinical inertia, which fails to implement evidence-based diagnostic tools 8 , makes practice predominantly replicative 9 . Thus, the formation of professionals who can successfully translate people's complaints into meaningful diagnoses is deficient, to say the least, calling for innovative approache...
