Cohort study of a simple 'Step-Up' regimen with the Asthma Control Test

Abstract

This prospective cohort study investigates whether simple guideline-based asthma management using a 'Step-Up' regimen with the Asthma Control Test score improves asthma control in patients with inadequately controlled asthma in primary care. Seventy out of ninety-three (75%) participants achieved a score of >19 (good control), and the mean increase in Asthma Control Test score was 6.0 (95% confidence interval: 5.3-6.8), P < 0.001. The improvement was independent of baseline inhaled corticosteroid use.
