Abstract

The causes of childhood asthma death were analyzed on 206 patients from 0 to 34 years of age, who had died from 1988 to 2010 and were reported to the committee until October in 2010. Subjects analyzed were divided into two groups by year to study the annual change in asthma death; the former group who died between 1988 and 1997 and the latter group between 1998 and 2010.<br> The number of annual asthma death has decreased since 1998.<br> Sex ratio (Male to female) was 98 to 63 (1.6 : 1) in the former group and 28 to 17 (1.6 : 1) in the latter group. The grades of asthma severity during one year before asthma death were severe 45%, moderate 30%, mild 26% in the former group and severe 38%, moderate 27%, mild 35% in the latter group respectively showing no differences between the groups.<br> Number of deaths in the hospital where they had usually visited were 73% in 0 to 6, 55% in 7 to 12 and 38% in older than 13 years of age showing that the older the asthmatic children became, the more the number of asthma deaths in the places other than the hospital increased. There were some cases of asthma death where school environment was concerned. The primary contributory cause for asthma death was unexpectedly rapid exacerbation 94% that was most important and the second cause was delay in time for visiting the hospital 83%. The medication in the most recent one year indicated increases in inhaled corticosteroids from 24% in the former group to 38% in the latter group and also a novel beta-agonist patch was recognized.<br> Analysis in the medication use before asthma death according to severity revealed that corticosteroid use in both inhaled and oral seemed inadequately less and the analysis for short acting beta agonist inhaler use showed same tendency.<br> Concerning other medications, numbers of cases reported were so few, clear conclusion seemed difficult to be drawn.<br>
