PURPOSE Imaging may produce unexpected or incidental fi ndings with consequences for patients and ordering of future investigations. Chest radiography in patients with acute cough is among the most common reasons for imaging in primary care, but data on associated incidental fi ndings are lacking. We set out to describe the type and prevalence of incidental chest radiography fi ndings in primary care patients with acute cough. METHODS We report on data from a cross-sectional study in 16 European primary care networks on 3,105 patients with acute cough, all of whom were undergoing chest radiography as part of a research study workup. Apart from assessment for specifi ed signs of pneumonia and acute bronchitis, local radiologists were asked to evaluate any additional fi nding on the radiographs. For the 2,823 participants with good-quality chest radiographs, these fi ndings were categorized according to clinical relevance based on previous research evidence and analyzed for type and prevalence by network, sex, age, and smoking status. RESULTS Incidental fi ndings were reported in 19% of all participants, and ranged from 0% to 25% by primary care network, with the network being an independent contributor (P <.001). Of all participants 3% had clinically relevant incidental fi ndings. Suspected nodules and shadows were reported in 1.8%. Incidental fi ndings were more common is older participants and smokers (P <.001). CONCLUSIONS Clinically relevant incidental fi ndings on chest radiographs in primary care adult patients with acute cough are uncommon, and prevalence varies by setting.
