Abstract
in English, Portuguese

Our objective was to evaluate the reproducibility of Asthma Control Questionnaire 7 (ACQ-7) in asthma patients, comparing our results against those obtained with the Global Initiative for Asthma (GINA) criteria. We evaluated 52 patients. Patients completed the ACQ-7, underwent spirometry, and were clinically assessed to determine the level of asthma control according to the GINA criteria, in two visits, 15 days apart. The ACQ-7 cutoff for uncontrolled asthma was a score of 1.5. The ACQ-7 showed good reproducibility, with a correlation coefficient of 0.73. The ACQ-7 identified a greater number of patients with uncontrolled asthma than did the GINA criteria; according to the GINA criteria, 47 patients (90.4%) presented with partially controlled asthma.

Nosso objetivo foi avaliar a reprodutibilidade do Asthma Control Questionnaire 7 (ACQ-7) em asmáticos e comparar os resultados com os critérios de controle da Global Initiative for Asthma (GINA). Foram avaliados 52 pacientes em duas visitas com intervalo de 15 dias entre si. Os pacientes responderam o ACQ-7, realizaram espirometria e foram avaliados clinicamente para verificar o controle da asma de acordo com a GINA nas duas visitas. Em relação ao ACQ-7, o ponto de corte para asma não controlada foi definido em 1,5. Os resultados de ACQ-7 demonstraram boa reprodutibilidade, com coeficiente de correlação de 0,73. O ACQ-7 identificou um maior número de pacientes com asma não controlada em relação aos critérios da GINA; segundo os critérios GINA, 47 pacientes (90,4%) tinham asma parcialmente controlada.
