Risk factors for death of asthma

This prospective cohort study included 865 adults with severe asthma. Patients were followed up until death or the end of the study (mean, 2 years).

Risk factors for death in asthma included:

- higher severity-of-asthma scores
- lower perceived asthma control scores

The highest risk patients seem to have severe asthma but they "do not feel it" until it is too late.
