Our data emphasize the high burden of disease, the persistence of inflammation and the existence of clinical possible phenotypes population sharing common features with published cohorts. Despite the necessity of further investigation into pathogenic mechanisms, this study with clinically difficult patient group may help to improve future asthma care.

Hospitalizations and medications seem to be the most important resources funded by the Brazilian public health system and by patients and their families. Although further studies are necessary, as information on cost of this disease is scarce in Brazil, these findings suggest that there is a potential room for improving severe asthma care among Brazilian patients.

The study suggests that the Brazilian version of the ECRHS is conceptually equivalent to the original and similarly reliable and may be used in international studies involving Portuguese-speaking respiratory patients.

Objective: To evaluate the understanding of asthma and the clinical improvement in patients with moderate or severe persistent asthma prior to and after their participation in an educational program presented during the routine outpatient visits. Methods: This was a prospective pilot study involving 164 patients over a two-year period. The educational program, presented to small groups on outpatient visit days, consisted of lectures divided into three parts: pathophysiology; environmental control; and treatment, including training in the inhalation technique. The program was evaluated using standardized questionnaires on clinical improvement and understanding of the disease. Results: By the end of the first year, 120 patients had completed three visits, and 51 of those patients were revaluated at the end of the second year. The mean age of the patients was 44 years, 70% were female, and 43% had up to eight years of schooling. The educational intervention significantly increased the understanding of the disease (p < 0.001), and allowed greater clinical improvement (p < 0.05) with a decrease in the use of oral corticosteroids, fewer visits to the emergency room and fewer days missed from work or school. Conclusions: The educational program offered during the routine outpatient visits of adult patients with asthma at our clinic resulted in a progressive long-term increase in knowledge, as well as in clinical improvement.Keywords: Asthma; Adult; Patient education as topic. ResumoObjetivo: Avaliar o conhecimento da doença e a melhora clínica de portadores de asma persistente moderada e grave antes e após a sua participação em um programa de educação realizado durante as visitas ambulatoriais de rotina. Métodos: Trata-se de um estudo piloto, prospectivo que envolveu 164 pacientes durante um período de dois anos. O programa de educação, oferecido para pequenos grupos nos dias de consulta, consistiu de aulas expositivas divididas em três módulos: fisiopatologia, controle ambiental e tratamento, incluindo o treinamento da técnica inalatória. Para a avaliação do programa, foram utilizados questionários padronizados sobre a melhora clínica e conhecimento da doença. Resultados: Em um ano, 120 pacientes completaram três visitas, e 51 pacientes foram reavaliados em dois anos. A média de idade dos pacientes foi de 44 anos, 70% eram do sexo feminino, e 43% tinham até oito anos de educação formal. A intervenção educacional aumentou o conhecimento da doença de forma significativa (p < 0,001) e possibilitou melhora clinica (p < 0,05) com a diminuição do uso de corticosteroide oral, redução de visitas ao serviço de emergência e menor número de faltas ao trabalho ou escola. Conclusões: O programa de educação expositivo oferecido durante a rotina de atendimento ambulatorial de adultos asmáticos de nosso serviço mostrou um crescente e progressivo aprendizado em longo prazo. Paralelamente, promoveu melhora clínica.Descritores: Asma; Adulto; Educação de pacientes como assunto. to participate in educational programs due to major ...
