[Assessment of thoracic X-ray readings by emergency room physicians at a university hospital]

Background:
We aimed to find out whether systematic reading of chest radiography (CRx) by radiologists in the emergency unit might lead to a higher diagnostic efficiency and improve health care.
Material And Method:
Descriptive study of consecutive admissions during 3 months in an internal medicine department. We registered the CRx interpretation by the emergency unit physician first, and a radiologist the next day. In cases with different interpretations, we assessed whether these differences would have modified the treatment.
Results:
The overall disagreement between the emergency room physician and the radiologist was 13.7%. In 19 of 29 cases with different readings, the radiologist interpretation was in agreement with the final diagnosis. In 7 of these 19 cases, the radiologist reading of CRx would have led to a positive change of treatment. However, differences between both physicians were not statistically significant.
Conclusions:
There seems to be a higher diagnostic efficiency when the emergency room physician interpretation of CRx is complemented by a radiologist.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
