Introduction: Several tools are useful in detecting uncontrolled asthma such as asthma control test (ACT) and GINA criteria. Objective: Assess the concordance between ACT and GINA criteria in evaluation of asthma control. Methods: a cross-sectional study including 106 asthmatics followed up in the outpatient allergology department of Pneumology 1 at Abderrahmane Mami Hospital, between April 2020 and September 2022. Results: Mean age was 45±15 years with female predominance (sex ratio H/F=0.3). Regarding the distribution of ACT score vs GINA classification, among the 24 patients with ACT?15, 18 patients (75%) were labeled as uncontrolled on GINA, 6(25%) as partially controlled and none labeled as controlled (p<10-3). Among patients with ACT between 16 and 19, 36.8% were labeled as partially controlled and 36,8% as uncontrolled on GINA (p=0.029). About patients with ACT score> 19, 87.3% were labeled as controlled, 11.1% as partially controlled and only one patient was labeled as uncontrolled on GINA (p<10-3). The mean ACT score was higher in patients with controlled asthma on GINA( 23.3±2; p<10-3), and was lower in patients with partially controlled asthma and uncontrolled asthma on GINA (17.55±4; p<10-3 and 12.85±4; p<10-3 respectively), so a negative correlation was found between the number of GINA ITEMS and the ACT score (p<10-3, r= -0.77). Conclusion: ACT correlate well with GINA criteria in predicting asthma control. However ACT seems to be a source of error in the evaluation of control due to the subjectivity of the answers and the low level of education in the Tunisian population. Hence GINA items seem to be the more appreciated tool to assess asthma control in our population.
