BACKGROUND: To deal with patients suffering from dyspnoea, it is crucial for
general practitioners to know the prevalences of different diseases causing
dyspnoea in the respective area and season, the likelihood of avoidable
life-threatening conditions and of worsening or recovery from disease. AIM: Aim
of our project was to conduct a systematic review of symptom-evaluating studies
on the prevalence, aetiology, and prognosis of dyspnoea as presented to GPs in a
primary care setting. METHODS: We did a systematic review of symptom-evaluating
studies on dyspnoea in primary care. For this we included all studies
investigating the complaint "dyspnoea" as a primary or secondary consulting
reason in general practice. Apart from qualitative studies, all kind of study
designs independent from type of data assessment, outcome measurement or study
quality were included. Symptom-evaluating studies from other settings than
primary care and studies which exclusively included children (age <18 years) were
excluded from the review. Studies selecting patients prior to recruitment, e.g.
because of an increased probability for a particular diagnosis, were also
excluded. RESULTS: This systematic review identified 6 symptom evaluating studies
on dyspnoea in the primary care setting. The prevalence of dyspnoea as reason for
consultation ranges from 0.87 to 2.59 % in general practice. Among all dyspnoea
patients 2.7 % (CI 2.2-3.3) suffer from pneumonia. Further specification of
underlying aetiologies seems difficult due to the studies' heterogeneity showing
a great variety of probabilities. CONCLUSION: There is a great lack of empirical
evidence on the prevalence, aetiology and prognosis of dyspnoea in general
practice. This might yield uncertainty in diagnosis and evaluation of dyspnoea in
primary care.
