Minimizing radiation doses during the procedures is essential. We investigated whether fine-tuning the radiation protocol reduces radiation doses in the cardiac catheterization laboratory. In January 2016, we implemented a new protocol with reduced radiation doses in the Hospital de Jerez catheterization laboratory. We analyzed 170 consecutive coronary interventional procedures (85 of which were performed after the new protocol was implemented) and the personal dosimeters of the interventional cardiologists who performed the procedures. Overall, the low-radiation protocol reduced air kerma (dose of radiation) by 44.9% (95% CI, 18.4%-70.8%; P=0.001). The dose-area product decreased by 61% (95% CI, 30.2%-90.1%; PenCardiac catheterization/adverse effectsoccupational exposure/prevention & controlpatient safetyradiation exposure/prevention & controlradiation monitoringradiation protection/methodsradiography, interventional/adverse effectsrisk factorsworkforceAgedCardiac CatheterizationCoronary AngiographyFemaleFluoroscopyFollow-Up StudiesHumansIncidenceMaleMiddle AgedOccupational ExposureRadiation DosageRadiation ExposureRadiation InjuriesRetrospective StudiesRisk AssessmentRisk FactorsSpainresearch article31708696open access10.14503/THIJ-17-65481526-6702PMC6827476https://doi.org/10.14503/thij-17-6548https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6827476/pdf
