Asthma control cost-utility randomized trial evaluation (ACCURATE): the goals of asthma treatment

BMC Pulmonary Medicine

Table 1 Levels of Asthma Control

Characteristic	Strictly Controlled (All of the following)	Sufficiently Controlled (Any measure present in any week)	Uncontrolled
Daytime symptoms	None (twice or less/week)	More than twice/week	Three or more features of sufficiently controlled asthma present in any week
Limitations of activities	None	Any
Nocturnal symptoms/awakening	None	Any
Need for reliever/rescue treatment	None (twice or less/week)	More than twice/week
Lung function (FEV₁)	Normal	< 80% predicted
Exacerbations*	None	1^st moderate exacerbation	≥ 2 moderate exacerbation^† or severe exacerbation

*modified from the GINA guidelines; the presence of an exacerbation influences the level of asthma control at baseline or at an exacerbation. If one or more exacerbations have led to an adjustment in treatment, this category starts at 0 again. At baseline: treatment levels only will be adjusted when exacerbations were present ≤ 3 months prior to the study: † during the same treatment regime.
