Morbidity and mortality of asthma.
Morbidity and mortality of asthma has been on the upswing since the 1960s, as marked by increased hospitalizations with asthma since the early 1980s. This has not been explained adequately. The possibility of change in the natural history or increased exposure to environmental irritant chemicals or allergens has been suggested by some. There probably has been better recognition and diagnosis of asthma by distinguishing it from bronchitis, recurrent croup, and bronchiolitis in children. Despite evidence to suggest that this is the case, there are still some missing factors. The increase in asthma mortality is more understandable when one considers the fact the management of asthma has changed greatly in the past two decades. The use of corticosteroids orally, parenterally, and by inhalation has been a double-edged sword. There is no doubt that many asthmatics have a much improved sense of well-being and have lived more normal lives due to the use of corticosteroids. The inability of some patients, parents, or physicians to perceive impending respiratory difficulty, however, may result in underuse of drugs, including corticosteroids, leading to increased mortality. Other factors have led to increased mortality from asthma in recent years, and they include arrhythmias with combinations of theophylline, beta-agonists, and hypoxia. The psychological factors attendant to adolescence and psychological problems are probably quite important in the recent upsurge in asthma deaths in the 15- to 25-year age group. Many deaths are occurring outside of the hospital environment and may be largely preventable. There must be increased awareness by the patient, the family, and the physician. In view of the increased hospitalizations, the total number of deaths is not increasing at an alarming rate, yet it is necessary to make all of us who care for asthmatics aware and take corrective action as soon as we are aware of an asthmatic with respiratory problems.
