In plain language
At one US center, a package of radiation reduction measures in the cath lab was followed by roughly halved patient air kerma in diagnostic catheterization and about one-third lower in percutaneous coronary intervention (PCI). Staff dose was not measured directly.

What it found
In diagnostic catheterization, median total air kerma fell by more than half after the radiation reduction initiative.
Key figures: median 396 vs. 857 mGy; p < 0.001
In PCI, total air kerma was significantly lower after the initiative.
Key figures: 1265 vs. 1994 mGy; p < 0.001
Fluoroscopy- and acquisition-based air kerma rates and air kerma area product also fell in matched and unmatched cohorts.
The reduction was sustained over the 7-year post-initiative period.
Limits to keep in mind
Single-center before-after retrospective comparison with propensity matching; only patient dose metrics were reported, so staff dose reduction was not directly measured, and the specific measures and sample sizes are not described in the abstract.
