Determinants for the course of acute sinusitis in adult general practice patients.

摘要

BACKGROUND: Although the prognosis of acute sinusitis is important, little is known about it and the factors predicting its course in a general practice population. OBJECTIVE: To determine the course of acute sinusitis and factors predicting it in adults in general practice. METHODS: The prognostic value of demographic and clinical factors and the patient's emotional state, for example anxious or depressed, were determined prospectively by means of multivariate analysis. MAIN OUTCOME MEASUREMENTS: Resolution of facial pain, resumption of daily activities, and the patient's reported improvement. Factors with a significant predictive value were used to classify the patients into three different groups: quick, moderate, and slow recovery. RESULTS: The median time from enrollment to recovery was six (range percentile 25-75: 4-10) days in a population of 177 patients. Factors predictive of a prolonged clinical course were: female sex (hazard ratio (HR) 0.60; 95% confidence interval (CI) 0.42 to 0.83), history longer than 14 days before inclusion (HR 0.62; 95% CI 0.41 to 0.94), headache, cold, or cough as a reason for the encounter (HR 0.65; 95% CI 0.44 to 0.96), and absence of cervical adenopathy (HR 0.71; 95% CI 0.51 to 0.96). Antibiotic treatment did not influence the course of disease. The median time to recovery was three days for patients with a quick, five days for those with a moderate, and seven days for those with a slow recovery. CONCLUSION: In general practice acute sinusitis is mostly a self limiting disease. A limited number of characteristics are predictive of a (slightly) prolonged clinical course of acute sinusitis in general practice.
