Figure produced by Blakey JD Figure produced by Blakey JD. A representation of a potential coordinates system to inform asthma management. Ongoing poor daily control results in escalation along the y axis and ongoing risk of severe asthma attack leads to escalation along the x axis. Letters represent example patients.

Reduce magnitude of loss
Intervene early >20% less likely to get OCS Get them days later in the episode 2-3 x more likely to come back to the ED More likely to report ongoing problems 2 week later Both pregnant and non-pregnant women have 65% concordance with OCS bursts Cydulka RK et al.
