Abstract

This study compares the characteristics of fatal asthma patients and those of near-fatal asthma patients who had experienced severe life threatening attacks. Data from 67 fatal asthma patients and 80 near-fatal asthma patients were analyzed. The mean age of fatal asthma cases were older than near-fatal asthma cases, 51.9 yrs and 44.3 yrs, respectively. Similarities of the two cases were seen in sex, type of asthma and severity of asthma. The experiences of previous life-thretening asthma did not differ in both groups (43.3% of fatal vs 40.0% of near-fatal). From the viewpoint of type of development of severe exacerbation, rapid exacerbation was more frequent in fatal cases than near-fatal cases, but acute exacerbation after unstable asthma was more in near-fatal asthma. Seventy-six percent of all asthma deaths occured at home or on the way to the emergency department. The rate of delay of receiving medical care was significantly higher in fatal cases (72%) than near-fatal cases (26%). There was no significant difference in the frequency of medical management before fatal or near-fatal episode such as oxygen therapy, mechanical ventilation. Use of ambullance, visiting emergency department, previous hospitalization between the two groups. The profile of fatal cases was almost same to that of near-fatal cases except delay of receiving medical care. In conclusion, the analysis of near-fatal cases was very important to make clear the causes of asthma death.
