In plain language

In 764 cardiac catheterizations, adding an accessory lead shield for nurses and scrub technologists was associated with roughly 35% to 64% lower measured radiation dose for these staff, depending on adjustment.

Summary based on
the abstract

What it found

  • Accessory lead shield use was associated with 62.5% lower normalized dose per case among technologists.

    Key figures: 62.5% lower; 2.4 [4.3] vs 0.9 [2.8] μSv/[mGy × cm2] × 10-5; p < 0.001

  • Accessory lead shield use was associated with 63.6% lower normalized dose per case among nurses.

    Key figures: 63.6% lower; 1.1 [3.1] vs 0.4 [1.8] μSv/[mGy × cm2] × 10-5; p < 0.001

  • After multivariate adjustment, shielding remained independently associated with lower dose among technologists.

    Key figures: 34.2% reduction; 95% confidence interval (CI) 20.1% to 45.8%; p < 0.001

  • After multivariate adjustment, shielding remained independently associated with lower dose among nurses.

    Key figures: 36.4% reduction; 95% CI 19.7% to 49.6%; p < 0.001

  • Shielding for staff other than physicians is not commonplace in catheterization labs.

Limits to keep in mind

Sequential two-phase observational design rather than randomization, so time-related changes in practice may confound results; dosimeter-based dose measures, not health outcomes; single-setting details not reported in the abstract.

How this summary was made

ORSIF prepared this summary with AI assistance from the abstract of the paper. A program then checked that the passage supporting each finding appears word for word in that source. A person has not yet reviewed each summary, so read the original before relying on a number. ORSIF summarizes research and does not endorse any product or company.
