Abstract To clarify recent trends in adult asthma mortality, the Asthma Death Investigation Committee of Japan studied the clinical characteristics of 295 patients who died of asthma between 1995 and 1997. Males were slightly more than females among the death cases. Approximately half of the patients ranged in age from 60 to 79 years. Tendency to increase of death among young male adults continued. One third of the patient deaths involved the asphyxic type, while status asthmaticus was the cause death in 21.9\%. Half of the asthmatics died in hospitals or emergency rooms, and places where the fatal attacks occurred were mainly patients' houses. The main cause fatal asthma attacks was respiratory infection, followed by fatigue, stress, and discontinuation of medication. Most of the patients were classified moderate or severe type of asthma 1 month before death. Histories of life-threatening attacks and hospitalization due to severe attacks, irregular visits to the hospital, low compliance, and insufficiency of corticosteroid treatment were suggested as the main risk factors in adult asthma deaths.
