Death from asthma.

The factors associated with the deaths of 31 asthma patients were examined. The subjects, whose deaths occurred in the period 1967 through 1979, had all received some care at the Hospital for Sick Children in Toronto, but only nine died there. The greatest single cause of death was the inappropriate use of beta-agonists, with or without the concurrent use of epinephrine. In seven patients an asthma attack that occurred outside hospital progressed so rapidly that there was insufficient time for them to obtain adequate therapy. In five cases the assessment of the patient's condition or the therapy recommended by the attending physician appeared to have been inadequate. Two patients suffered an acute attack in hopital and did not respond to treatment that appeared to have been adequate. In six cases the available information was insufficient to indicate the cause of death. Over half (18) of the deaths occurred in teenagers. Various ways of preventing death from asthma are discussed, including better education of physicians and patients, adequate management of factors that provoke bronchospasm, sufficient follow-up -- especially in teenagers -- and the use of approaches with teenagers that encourage better compliance.
