Changes in asthma mortality in England and Wales since 2001.

The number of deaths from asthma in England and Wales has not changed significantly over the last decade. This lack of improvement has received attention from both national asthma guidelines and the media. We examined asthma death data from the Office for National Statistics, stratified by age band. Every 5-year age band below the age of 80 years has seen a large reduction in mortality between 2001 and 2017, whereas numbers of asthma deaths have increased by 81% for people aged 80 years or above. This increase in older people dying from asthma requires explanation.
