Components of control | Classification of asthma control (youths ≥12 years of age and adults) | |||
Well-controlled | Not well-controlled | Very poorly controlled | ||
Impairment | Symptoms | ≤2 days/week | >2 days/week | Throughout the day |
Nighttime awakenings | ≤2 times/month | 1 to 3 times/week | ≥4 times/week | |
Interference with normal activity | None | Some limitation | Extremely limited | |
Short-acting beta2-agonist use for symptom control (not prevention of EIB) | ≤2 days/week | >2 days/week | Several times per day | |
FEV1 or peak flow | >80% predicted/personal best | 60 to 80% predicted/personal best | <60% predicted/personal best | |

Risk | Exacerbations | 0 to 1/year | ≥2/year (refer to legend) | |
Consider severity and interval since last exacerbation | ||||
Progressive loss of lung function | Evaluation requires long-term follow-up care | |||
Treatment-related adverse effects | Medication side effects can vary in intensity from none to very troublesome and worrisome. The level of intensity does not correlate to specific levels of control but should be considered in the overall assessment of risk. |
ACQ: Asthma Control Questionnaire (Juniper et al. 1999b); ACT: Asthma Control Test (Nathan et al. 2004); ATAQ: Asthma Therapy Assessment Questionnaire (Vollmer et al. 1999); EIB: exercise-induced bronchospasm; FEV1: forced expiratory volume in 1 second; N/A: not applicable.
* ACQ values of 0.76 to 1.4 are indeterminate regarding well-controlled asthma.Do you want to add Medilib to your home screen?
