The ACT and the ATAQ Are Useful Surrogates for Asthma Control in Resource-Poor Countries with Inadequate Spirometric Facilities

Abstract

The ACT and ATAQ are the objective and reliable tools in determining asthma control due to their strong correlation with the FEV1 and the asthma-specific health-related quality of life. Use of either questionnaire routinely will identify more patients with poor asthma control even when spirometry services are not readily available.
