[Diagnosis and treatment of acute sinusitis by Danish general practitioners].

We studied Danish general practitioners' (GP) weighting of symptoms, clinical findings and use of paraclinical investigations when diagnosing acute sinusitis in adults. Questionnaires were sent to 300 representative GPs. Sixty-seven percent answered the questionnaire. The GPs weighted pain and tenderness on application of pressure over the sinuses as the most important symptom and finding. Only a few used paraclinical investigations. The GPs estimated their own diagnostic certainty as being 70%. Detumescent nose-drops were prescribed in 95% of the cases, and antibiotic treatment was given in 50%, most frequently as V-penicillin.
