5 -1 - 1 - Dermatologists’ Knowledge Towards Computed Tomography Radiation dose in the Kingdom of Saudi Arabia


Objective: To assess the knowledge of Saudi dermatologists regarding protection against hazards of ionizing radiation during computed tomography (CT) procedure. Methods: It was a cross-sectional research design, comprising of dermatologists. A study questionnaire was designed and developed by the researcher, which included personal characteristics of the participants and statements on their knowledge regarding risks of exposing patients to ionizing radiation during radiological investigations. Results: This study included 120 dermatologists. The majority of participants (93.3%) did not attend any course on protection against ionizing radiation. Only 19.2% were familiar with the ALARA principle, while 51.7% were aware of a link between radiation exposure and increased risk of developing cancer. Recommended dose limits (1.7%) concern about radiation doses delivered to patients (31.79%) from requested CT, and alternative imaging investigations (80%) other than CT known to the participants, was found unsatisfactory. Most participants (86.7%) had poor knowledge regarding exposure to ionizing radiation. Attending courses on radiation protection was significantly associated with better knowledge (p<0.001). Conclusion: Knowledge of most Saudi dermatologists regarding hazards of ionization radiation is poor. This can be attributed to their lack of exposure to any courses on radiation protection. Awareness of Dermatologists can be done by conducting more workshops and associated seminars, in order to enhance their knowledge regarding this issue.
