The Shift from Asthma Severity to Control
In developing the ACT for asthma needs, 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 for the asthma control test questionnaire 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 in our questionnaire for asthma patients to more appropriately monitor improvement or decline in a patient’s asthma control.
