Evaluation of Moroccan physician’s knowledge about radiation doses and risks from pediatric computed tomography

Abstract

The large use of Computed Tomography Scan (CT scan) is a principal cause of increasing medical ionizing radiation exposure. Children are considered a population at risk for the occurrence of radiation-induced pathologies, and the implementation of radiation protection measures relies on the knowledge and skills of healthcare professionals. This analytical cross-sectional study aimed to assess the knowledge of Moroccan physicians prescribing pediatric CT scan examinations on the radiation protection of patients, radiation doses, and potential health risks of radiation exposure from CT scan. A questionnaire was distributed to all clinicians on the medical staff who prescribe pediatric CT examinations in five Moroccan pediatric hospitals. The questions have a focusing on prescribers’ practices and their knowledge of patient radiation protection, radiation doses, the potential health risks of radiation exposure from CT scan, and training on radiation protection. One hundred and ninety-two questionnaires were submitted to prescribers and among them, 88% responded. The data were analyzed using the Statistical Package of Microsoft Office Excel. Knowledge gaps regarding CT scan radiation doses and associated health risks among Moroccan physicians are evident from this study results, initial and continuing training of health care staff and the implementation of referral guidelines for medical imaging could lead to improve practitioners’ knowledge of patient radiation protection.
