Asthma management and morbidity in Australian general practice: the relationship between patient and doctor estimates.
The aims of this study were to describe asthma management and morbidity in patients attending general practitioners in Australia, and to assess the relationship between patient reports and those of their general practitioner (GP). The sample comprised consecutive patients attending 46 general practitioners chosen at random in five regions of New South Wales, Australia. A total of 4538 patients were screened, 607 (13.4%) reported ever having diagnosed asthma, and the 501 who reported asthma in the previous 12 months completed a detailed questionnaire. Three hundred and thirty-four patients also had information about their asthma management recorded by their GP. The patient questionnaire asked about asthma symptoms, therapy, lung function measurement, and asthma-related morbidity. The GP questionnaire asked the doctor to record similar information about the patients. Two-thirds of the patients used regular inhaled beta 2-agonist medication, and one-half reported using preventive therapy. Only 24% owned a peak flow meter and 9% had a written plan of action for asthma attacks. Although preventive therapy and airway function assessment were more common in those with frequent symptoms (> 2-3 times per week), this group were still sub-optimally managed. In the matched sample (n = 334), doctors reported prescribing bronchodilator and preventive medication, measuring airway function and recommending peak flow meter use more often than suggested by patient-reported data. The study concludes that many patients do not attend for regular review, and that management remains sub-optimal, particularly in young adults. Data from patient surveys may underestimate clinical practice, as assessed from doctors' records. This should lead to patient-derived estimates of management being interpreted with caution in epidemiological studies. Further attention to patient understanding and compliance with prescribed asthma management advice is needed in order to better manage asthma in the community.
