AIM: The aim of the study was to determine the reliability and validity of the agreement between the Asthma Control Test (ACT) and Global Initiative for Asthma (GINA) in classifying asthma control in the Czech Republic. METHODS: A sample of 316 people with asthma was recruited from the Clinic of Tuberculosis and Respiratory Diseases of the University Hospital in Ostrava between November 2011 and July 2012. Two questionnaires were used in this study, the Asthma Control Test and Mini Asthma Quality of Life Questionnaire (Mini-AQLQ). Regardless of the questionnaire results the asthma specialist assessed the asthma control status of enlisted patients according to the criteria described in the GINA 2006 guidelines. RESULTS: The internal consistency of the five-item ACT was good. The ACT score of ≥20 predicted GINA-defined controlled asthma in 29% of cases with a sensitivity of 65% and specificity of 89%. The kappa level of agreement between the ACT classification and GINA classification of asthma control was 0.29, suggesting fair agreement. The ACT score showed the strongest correlation with the specialists' rating, followed by the FEV1 percent predicted. Overall, in line with previous studies we confirmed significant relationship between the ACT scores and FEV1 and health related quality of life. CONCLUSIONS: ACT is a reliable and simple tool that might be a significant asset in the management of outpatients with asthma in the Czech Republic. The ACT score correlates well with lung function parameters and health related quality of life. It appears to be a good tool to predict GINA-defined 'not-controlled asthma'.
