Prevalence of dysfunctional breathing in patients treated for asthma in primary care: cross sectional survey
Open accessAbstract
Objectives: To estimate the prevalence of dysfunctional breathing in adults with asthma treated in the community. Design: Postal questionnaire survey using Nijmegen questionnaire. Setting: One general practice with 7033 patients. Participants: All adult patients aged 17-65 with diagnosed asthma who were receiving treatment. Main outcome measure: Score23 on Nijmegen questionnaire. Results: 227/307 patients returned completed questionnaires; 219 (71.3%) questionnaires were suitable for analysis. 63 participants scored 23. Those scoring 23 were more likely to be female than male (46/132 (35%) v 17/87 (20%), P=0.016) and were younger (mean (SD) age 44.8 (14.7) v 49.0 (13.8, (P=0.05). Patients at different treatment steps of the British Thoracic Society asthma guidelines were affected equally. Conclusions: About a third of women and a fifth of men had scores suggestive of dysfunctional breathing. Although further studies are needed to confirm the validity of this screening tool and these findings, these prevalences suggest scope for therapeutic intervention and may explain the anecdotal success of the Buteyko method of treating asthma. What is already known on this topic: Abnormal breathing patterns may cause characteristic symptoms and impair quality of life Effective interventions exist for dysfunctional breathing Dysfunctional breathing has been described in patients attending hospital respiratory clinics What this study adds: 29% of adults treated for asthma in primary care had symptoms suggestive of dysfunctional breathing Affected patients were more likely to be female and younger, but no differences were found with severity of asthma Some patients with asthma may benefit from breathing therapy

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
