Patient-physician opinion concordance could play a key role in asthma control. There have been no studies evaluating this association in large samples of patients.
Objectives: To determine opinion concordance between asthma patients and their pulmonologists on the impact of the disease and to correlate concordance to asthma control.
Methods: This was a cross-sectional multicentre study including 1160 patients and 300 pulmonologists. Patient-physician concordance rates were assessed by two semi-structured qualitative questionnaires: (1) impact of the disease and (2) treatment satisfaction. Subsequently, participating pulmonologists determined the concordance between their perceptions and their patient's. Sociodemographic and clinical data were recorded for all patients.
Results: In 53.6% of cases, asthma was controlled. The rate of patient-pulmonologist concordance on disease impact on patient daily life was 57%, with physicians underestimating the impact (compared to patients) in 26% of cases. Concordance on satisfaction with treatment was 56%, with physicians underestimating satisfaction in 26% of cases. Patient-physician discordance rates were significantly lower among patients with controlled asthma (29 and 32.1%) than those with poor control (73.7 and 73.1%).
Conclusions: Patient-pulmonologist concordance on perceptions of disease impact is low, particularly in uncontrolled asthma. This poor concordance should be addressed in education programmes, particularly for patients with uncontrolled symptoms.
