The management of newly identified asthma in primary care in England

To establish by case note review how people with newly diagnosed asthma were treated in general practice.

A retrospective cross-sectional survey was carried out in twelve general practices from the MRC General Practice Research Framework. Children between their 3rd and 8th birthdays and adults 16 years and over were identified with newly diagnosed or treated asthma from computer records with further details obtained from a case record search. The main outcome measure was the time of recorded asthma diagnosis and the time of first prescriptions for inhaled corticosteroids.

For 41% of children and 53% of adults with a diagnosis of asthma and inhaled corticosteroids, inhaled corticosteroids were prescribed before or on the same day as the diagnosis of asthma was recorded. Diagnosis tended to be made on the basis of a patient's medical history with fewer than 20% of patients having results of any tests recorded in their medical notes. The time from first respiratory consultation to inhaled corticosteroid prescription was statistically significantly shorter in those children for whom a diagnosis of asthma was recorded (p=0.038) compared to those children without a recorded diagnosis of asthma.

Inhaled corticosteroids are frequently prescribed before a diagnosis of asthma is recorded. A diagnostic label of asthma in children significantly reduces the length of time from the date of first respiratory consultation to inhaled corticosteroid prescription. If inhaled corticosteroids are to be prescribed early there must be an improvement in the diagnosis of asthma in primary care, including the recording of results in patient's medical notes.
