A multinational study of treatment failures in asthma management.

SETTING

Emergency rooms.

OBJECTIVE

To assess quality of care and its determinants for asthma patients before emergency room treatment.

DESIGN

Consecutive patients with acute severe asthma attending emergency rooms were questioned about the severity of their disease and treatment in the previous 4 weeks. Prescriptions of inhaled corticosteroids were recorded. Other outcomes included self-reported adherence to treatment and loss of work.

RESULTS

Thirteen centres in 11 countries recruited 1156 patients. Only 36% of patients with persistent asthma had been prescribed an adequate dose of inhaled corticosteroids. This percentage improved in those receiving regular care from the same doctor (OR 2.86, 95%CI 1.38-5.96), and was at least as good for the 10% of patients receiving 'private' health care (OR 3.08, 95%CI 1.69-5.62). Forty-four per cent of patients had health insurance covering some asthma medications. These patients were more likely to be receiving adequate inhaled corticosteroids (OR 1.74, 95%CI 1.17-2.58), and reported better adherence than those without insurance (OR 3.00, 95%CI 1.64-5.50). Of those on adequate inhaled corticosteroids, 18% had lost work in each of the 4 previous weeks compared with 59% among those more than one treatment step below the recommended dose.

CONCLUSIONS

Access to adequate treatment is critical for better management of asthma.
