Asthma therapy in the observation unit.

The management of asthma is a commonly encountered clinical problem. There have been major advances in the treatment of asthma, including an increase in the drugs available for treatment, as well as in knowledge of the pathophysiology of the disease. Despite these advances, however, the prevalence, morbidity, and mortality for asthma have shown a disturbing upward trend over the past few decades. Experience with the OU management of asthma has shown many advantages: decreased inpatient hospitalization, better quality of life for patients, higher patient satisfaction, cost-effectiveness, and effective patient care. It is estimated that 60% to 70% of asthmatic patients could be treated in an ED observation unit instead of in an inpatient hospital ward. There is a tremendous opportunity for the OU management of asthma to improve patient care, as well as decrease costs, thereby reducing asthma morbidity and mortality.
