Asthma Care Practices in Chicago-Area Emergency Departments: Asthma Treatment

As seen in Table 2, use of arterial blood gases in the initial assessment of persons with asthma was reported infrequently (9.1 ± 1.8% of patients). However, arterial blood gases were much more likely to be obtained for persons presenting with a severe asthma exacerbation (72.3 ± 3.8% of patients). Chest radiography was a common assessment tool for selected indications. Specifically, when the diagnosis was in doubt, 85.0 ± 2.8% of patients had a chest radiograph; 79.2 ± 2.3% of patients received one if they were both wheezing and febrile; and 70.1 ± 3.8% of patients received one if they were presenting with wheezing for the first time.
Asthma Treatment
The average estimated length of stay for an asthma-related ED visit was 3.0 ± 0.1 h (see Table 3). The average disposition time (ie, the decision to admit) for patients with asthma was estimated at 2.5 ± 0.2 h.
All of the respondents reported use of p-agonists as initial pharmacotherapy. All but one ED reported use of nebulizer-administered p-agonist as initial therapy. One ED reported administering p-agonist therapy via me-tered-dose inhaler. Theophylline was administered infrequently, to only 9.6 ± 1.6% of patients. Steroid use was also examined. Systemic steroids (either IV or po) were given to 62.3 ± 4.0% of asthma patients during the first hour of care, and to 73.2 ± 3.9% of patients at some time during their ED visit. Approximately 13% of the EDs reported low use of systemic steroids (administered to < 50% of asthma patients). canadian neighbor pharmacy viagra

The survey data indicate that supplemental oxygen was given to an average of 77.1 ± 3.4% of all persons treated for asthma.
Discharge and Follow-up Procedures
Table 4 describes several aspects of the discharge and follow-up procedures reported by the Chicago-area EDs. According to survey results, systemic steroids were prescribed at discharge for 55.9 ± 3.5% of patients with asthma (Fig 2). Inhaled steroids, cromolyn, and antibiotics were reportedly prescribed less frequently than systemic steroids; an average of 19.8 ± 2.9% of patients received inhaled steroids or cromolyn and 19.9 ± 1.7% received antibiotics. The respondents indicated that most asthma patients had a peak flow assessment at discharge (73.1 ± 4.1%). Only 25.0 ± 4.3% of patients were reported to have received a detailed follow-up appointment (with site and time specified) at discharge.
On average, the respondents estimated that 13.8 ± 1.1% of the persons with asthma seen in the ED had a relapse within 7 days.
