[Patient dose: implementation of a clinical practice assessment in medical imaging].
OBJECTIVE
To describe our experience with the implementation of a clinical practice assessment (CPA) with regards to radiation exposure in CT.


METHODS
Such a CPA requires that a reference level be available (DRL: diagnostic reference level) along with exposure data (CTDIvol and DLP) allowing for the evaluation of current practices, development of an action plan for improvement and future follow-up after implementation.


RESULTS
The action plan for improvements was elaborated based on the review of 641 radiation exposure data points collected over 1 year (CTDIvol and DLP). These data were compared to DRL values of corresponding anatomical regions. The implementation of dose guidelines enabled continuous quality improvement as opposed to punctual radiation dose assessments.


CONCLUSIONS
The requirement of recording patient exposure was an excellent opportunity to perform a CPA activity as described by the Haute Autorité de Santé (HAS) in its clinical audit process.
