In plain language
In one US electrophysiology lab, adding a radiation safety time-out was followed by a 21% lower median dose area product across 1,040 cases, plus more use of disposable shields. Staff dose itself was not reported directly.

What it found
Median dose area product fell by 21% after the radiation safety time-out was introduced.
Key figures: 18.7 Gy∙cm2 to 14.7 Gy∙cm2; 21% reduction (p = 0.007)
Median reference point dose decreased after the time-out.
Key figures: 163 mGy to 122 mGy (p = 0.011)
Use of sterile disposable protective shields and ultrasound-guided access increased significantly with the time-out.
Limits to keep in mind
Single-center before-after comparison without a concurrent control, so secular trends may contribute. Outcomes are patient dose metrics; staff dose was not directly measured in the abstract.
