In plain language
In one cath lab, lowering the default fluoroscopy frame rate to 7.5 frames/s and favouring low-dose acquisition cut patient air kerma by about a fifth in diagnostic cases and a third in percutaneous coronary intervention (PCI). Staff dose was not measured directly.

What it found
Median total air kerma during diagnostic catheterization fell after lowering the default frame rate and emphasising low-dose acquisition.
Key figures: 625 mGy in 2013 vs 798 mGy in 2012; P<0.001
Median total air kerma during PCI also fell significantly.
Key figures: 1675 mGy in 2013 vs 2463 mGy in 2012; P<0.001
Fluoroscopy- and acquisition-based air kerma rates were reduced in all projections after the measures.
Limits to keep in mind
Single-centre before-after comparison with propensity matching; measures patient air kerma only, with no direct staff dose measurement. Sample size not stated in the abstract.
