Further studies are needed to investigate patient attitudes and behaviours that influence use, delay or
avoidance of maintenance medications and action plan recommendations when asthma worsens [71], and
about ways of enhancing the delivery and use of written asthma action plans.
Exacerbation severity classification has been streamlined into mild/moderate, severe, and life-threatening. In
both primary care and acute care, the initial management of mild and moderate exacerbations is the same,
so they are combined into a single category.
