[Emergency room visits by patients with exacerbations of asthma].
We retrospectively analyzed patterns of emergency room visits by patients with exacerbations of asthma from December 1995 through November 1996. A total of 591 episodes in 198 patients were reviewed. The average age was 35.8 years, ranging from 15 to 71. The largest number of visits occurred in September. The number of visits per year ranged from 1 to 22; the mean was 2.9 per year. In patients who were followed on a regular basis at our institution, serve attacks accounted for 7.1% of the total, compared with 21.6 percent at other hospitals or outpatient clinics. We suspect that this difference was related to differences in the use of inhaled steroids. At our institution, 89% of patients were taking inhaled steroids; at other hospitals or clinics, only 21% were taking inhaled steroids. Of the 198 patients, 33 fulfilled one of the following criteria: (1) endotracheal intubation for respiratory failure or respiratory arrest, (2) respiratory acidosis (pH < 7.35) without endotracheal intubation; 27% of those patients had been given a diagnosis of mild asthma before the acute exacerbation. We conclude that patient education and standard guidelines for treatment of asthma, are very important for appropriate management of asthma, to prevent exacerbations and asthma-related deaths.
