Background: Pneumothorax is a potential life-threatening condition especially in patients with underlying disorders. In this study we compared the diagnostic accuracy of general practitioners and emergency medicine specialists in interpreting chest x-rays (CXR) suspected of having iatrogenic pneumothorax in emergency departments.
Methods: This cross-sectional study was conducted in Shahid Chamran Hospital in Tehran, Iran during 2008- 2010. The study was designed to compare the ability of general practitioners and emergency medicine specialists in diagnosing iatrogenic pneumothorax regarding 500 CXRs of one-hundred patients admitted for upper central venous catheterization.
Results: General practitioners and emergency medicine specialists could accurately (P<0.001) diagnose pneumothorax in 484 (96.8%) and 497 (99.4%) CXRs, respectively. None of the underlying causes of the condition affected the diagnostic accuracy of both physician groups (P>0.05).
Conclusion: These findings indicate that the diagnostic accuracy of emergency medicine specialists is significantly higher than those of general physicians. The diagnostic accuracy of both physician groups was higher than the values in similar studies that signifies the role of relevant training given in the emergency departments of the Hospital.
