Asthma: Definition of severe cases and use of high dose inhaled steroids – 3 April



Severe asthma definition 

In rapid guidance produced by NICE in light of Covid-19, it says – 

Be aware that severe asthma is defined by the European Respiratory Society and American Thoracic Society as asthma that requires treatment with high-dose inhaled corticosteroids (see inhaled corticosteroid doses for NICE’s asthma guideline) plus a second controller (and/or systemic corticosteroids) to prevent it from becoming ‘uncontrolled’, or which remains ‘uncontrolled’ despite this therapy.
