Awareness of the importance of decreasing death rates in the 1980s led to the development of asthma management plans or guidelines, first at national level, such as those for Australia2 and England,3 then at international level, and now globally.4 The aim of these plans was to achieve better care. One of the signs of this is decreasing death rates, especially in young people, in whom deaths are mostly avoidable (as shown by the falling rates in the presence of increasing prevalence of the disease). Since it is widely stated in the lay press that death rates from asthma are rising worldwide, the paper by Campbell et al in this week's BMJ (p 1439), showing that the mortality from asthma is decreasing in those under 65 years in England and Wales, is timely.5
