Asthma Control Test (ACT)
Patient-completed 5-question test for asthma control over past 4 weeks. Score <=19 = not well controlled; score <=15 = very poorly controlled.
Score interpretation
→ Continue current therapy; annual asthma review; consider step down if stable >=3 months; check inhaler technique; flu vaccine
→ Review inhaler technique and adherence; step up therapy (increase ICS or add LABA); identify and avoid triggers; respiratory review; asthma action plan
→ Urgent respiratory review; step up significantly; rule out alternative diagnoses; ICS-LABA combination; consider monoclonal antibodies if severe allergic/eosinophilic asthma; oral prednisolone if acute exacerbation
