The Use of Protective Equipment and Personal Monitoring in Fluoroscopy-Guided Procedures: A Case Study in Portugal

Introduction: The increasing use of fluoroscopy-guided procedures raises concerns about occupational radiation exposure, underscoring the need for effective radiation protection (RP) practices among healthcare professionals. The primary objective was to evaluate compliance with the use of personal protective equipment (PPE) and dosimeters, and to identify factors influencing safety behaviors among exposed workers. Methods: A cross-sectional, exploratory quantitative study was conducted at a hospital centre using a self-administered questionnaire in fluoroscopy-guided operating and interventional settings. The questionnaire collected sociodemographic and professional data, information on RP training, compliance with personal and collective protective equipment, and dosimeter use, as well as perceptions of occupational risk. Results: The study included 52 workers. Compliance with PPE use varied across professions, with radiographers reporting significantly higher use of lead aprons/skirt-coats and thyroid shields than other professionals (p < 0.05). The RP training was significantly associated with compliance with PPE and dosimeter use (odds ratios: 4.2-8.9). Older age groups reported lower compliance with PPE use. Overall, risk perception of radiation-related diseases was low (46.2%), and no statistically significant association was found between risk perception and reported PPE use. Regarding protection practices, 67% reported appropriate use of the apron/skirt-coat, 65% of the thyroid shield, and 62% of the dosimeter. The main barriers to PPE use were discomfort, weight, and inadequate cleaning, while forgetfulness was the most reported reason for not using the dosimeter. Conclusions: Inconsistent use of protective equipment and dosimeters may lead to unnecessary exposure and underestimation of occupational radiation doses, whereas RP training is a key determinant of compliance and a strong safety culture.
