概要	The ACQ is a 7-item self-report questionnaire developed by Juniper and colleagues at McMaster University in 1999 to assess the degree of asthma control in the previous one to two weeks. Unlike generic respiratory tools, the ACQ measures symptom-based control and rescue medication use, providing a simple yet psychometrically sound method for evaluating treatment efficacy. It is widely adopted in clinical trials, guideline-driven care, and routine asthma management to guide therapy titration and assess treatment response.	The BCS is a brief, symptom-focused assessment tool measuring the frequency and severity of three cardinal respiratory symptoms: breathlessness (dyspnea), cough, and sputum production. Developed in cardiopulmonary research as a pragmatic measure of disease burden in chronic heart failure and chronic obstructive pulmonary disease, the BCS provides rapid, patient-centered tracking of respiratory symptom trajectories. Unlike comprehensive quality-of-life questionnaires, the BCS concentrates solely on symptom phenotype, making it ideal for routine monitoring and longitudinal disease surveillance in busy clinical settings.
