[Evaluation of radiological medical practice at a hospital during night duty].

PURPOSE
To evaluate the radiological activity during night duty, in a University Hospital. Materials and methods. During 100 days, the radiological activity has been evaluated from examinations requiring radiologist (including US and CT, special X-ray examinations). The urgent nature and the agreement between the suspected disease and the final diagnose have been compared with the level of the clinician (medical student, resident, senior).


RESULTS
981 radiological examinations were performed on an emergency basis. In 39%, the examination was urgent or very urgent and for 61%, little urgent or non-urgent. The level of the clinician was correlated with the degree of emergency evaluated by the radiologist and with the agreement between suspected disease and the final diagnose (p<0. 0001).


CONCLUSION
During night duty, the medical activity in radiology is not justified only by emergency, but also by the continuous hospital activities. Better formation of the physician is required to limit the number of examinations.
