In plain language
In a pediatric interventional radiology service, showing staff their radiation dose in real time was linked to lower measured staff dose per minute of fluoroscopy, without changes in procedure or fluoroscopy time. Behavior change is a likely but unmeasured explanation.

What it found
Median staff dose was lower when real-time dose feedback was displayed than when it was hidden.
Key figures: 0.56 µSv/min vs 3.01 µSv/min; P < .05
Attending interventional radiologist dose fell significantly for procedures performed close to the patient, but not for those performed far away.
Procedure time, fluoroscopy time and normalized patient dose did not differ between phases.
Authors attribute the reduction most likely to increased compliance with protection equipment and dose-reduction techniques.
Limits to keep in mind
Single-site, non-randomized before-after design in pediatric interventional radiology (IR) with unreported sample size; the proposed mechanism (better compliance) was not directly measured.
