In plain language
Among 115 cardiologists at 27 centers, a 90-minute radiation safety course was followed by roughly halved patient dose in coronary angiography, more so when the team leader attended. Leaded glasses, gloves and caps were rarely used. Staff dose was not measured.

What it found
After a 90-minute radiation-reduction mini-course, median patient dose area product in coronary angiography roughly halved.
Key figures: Dose-area product (DAP) from 26.6 to 13.0 Gy × cm(2)
Fluoroscopic dose rate, fluoroscopy time and number of frames also fell after the course.
Key figures: fluoroscopic DAP/s -39%; fluoroscopy time -16%; frames -29%
In multilevel analysis, team leader participation and the course itself were associated with lower DAP, while operator experience mattered little.
Key figures: team leader -9.4 Gy × cm(2); mini-course -16.1 Gy × cm(2); experience -0.7 Gy × cm(2)/1000 CAs
Use of personal and room protection was uneven: aprons universal, but leaded glasses, gloves and caps rarely used.
Key figures: apron 100%, collar 89%, glasses 28%, gloves 3%, cap 1%
Authors conclude protective devices are underused in routine invasive cardiology.
Limits to keep in mind
Before-after design without a control group, with self-documented data on only 10 angiographies per cardiologist and short follow-up; outcomes are patient dose, not measured staff dose, and device use is self-reported.
