Knowledge and practices of interventional radiology staff regarding radiation protection

Abstract

Interventional radiology (IR) has become a widespread medical imaging technique, offering minimally invasive treatment options. However, IR procedures can expose patients and staff to substantial radiation risks, necessitating enhanced radiation protection practices. This study aimed to survey the knowledge and practices of interventional radiology staff regarding radiation protection. A cross-sectional study with a descriptive aim, based on a questionnaire was done. The study subjects were all healthcare personnel of all specialties having practiced in interventional radiology between 2019 and 2022 at the University Hospital Center of Rabat. The statistical processing was carried out using Microsoft Excel 2013® and the IBM SPSS Statistical program version 20 (IBM Inc. NY, USA). The results indicated that 59.4% of participants had not received any specific training in radiation protection, and 45% were unaware of the radiation-induced risks associated with interventional radiology procedures. Regarding safety practices, 75% of participants maintained a distance of at least 1 meter from the x-ray source, while only 6% used the lowest possible exposure settings. Concerning the use of radiation protection devices, 87.5% of participants wore a lead apron, 75% used a thyroid shield, 6.3% wore lead glasses, and 37.5% utilized suspended mobile screens, whereas 12.5% did not use any radiation protection devices. Additionally, 84% of participants wore their personal dosimeter, though not consistently. The knowledge and practices of most interventional radiology personnel are inadequate for effective radiation protection. Regular, ongoing training in radiation safety is essential to improve adherence to protection standards and enhance overall safety in clinical practice.
