Completed by the Caregiver, the ACT is an efficient, reliable and valid way to measure asthma control, with or without lung functioning measures, such as spirometry.
In developing the ACT, we followed a paradigm shift away from the severity of asthma and towards the ability to control the condition. Asthma experts assisted us in establishing cut-point scores to improve the survey’s clinical utility. These cut-points identify asthma patients with somewhat controlled or poorly controlled asthma. Additionally, clinically meaningful change score thresholds are available to more appropriately monitor improvement or decline in a patient’s asthma control.
