Acute asthma: emergency department management and prospective evaluation of outcome.
To determine the current management of acute asthma in the emergency department and to evaluate outcome we reviewed the charts of 99 patients aged 15 to 55 years who presented to the emergency department of a tertiary referral, university-affiliated hospital and were subsequently discharged with a diagnosis of acute asthma. Outcome was evaluated prospectively, with a structured questionnaire, by telephone. During the visit pulsus paradoxus was documented in four patients. Spirometry was done in 63 patients; postbronchodilator values ranged from 0.9 to 4.1 L. A total of 92 patients received inhaled bronchodilator therapy, most by wet nebulization. Sixteen patients received anticholinergic agents and three received theophylline. Ingested corticosteroids were given to 27 patients. Of the 71 patients contacted, a mean of 12 days after the visit, 26 (37%) had sought further medical attention, 19 at the emergency department; 9 had required admission. Forty-six patients reported that their condition had improved, but over 60% continued to have cough, sputum production, nocturnal waking and early-morning chest tightness. The results indicate that asthma continues to be undertreated in the emergency department and highlight the importance of routine spirometry in all patients and the need for systemic corticosteroid therapy.
