Differences between Saudi Arabian and Australian radiographers' knowledge and attitudes about paediatric CT doses

Purpose: Computed tomography (CT) is used extensively in diagnostic radiology for examination of human soft tissues and is widely used in the paediatric population. Researchers and government regulators have expressed concerns about the cancer risk of CT radiation on children. Th e authors surveyed Saudi Arabian and Australian radiographers to enable comparison of their attitudes and knowledge towards paediatric CT radiation dose. Methods: Radiographers from all exclusively paediatric public hospitals in Australia and Saudi Arabia were sent a structured, purpose-designed questionnaire. Data were analysed using univariate statistics. Results: 56 of 71 eligible Saudi Arabian radiographers (79%) and 50 of 83 Australian radiographers (60%) participated. Australian participants were more highly educated and had longer work experience than their Saudi counterparts, and undertook most forms of ongoing training and education signifi cantly more frequently. Australians' mean ratings of radiation risk for head and chest CT scans were similar to those given by Saudi respondents, but Australians' mean ratings for abdomen/pelvis CT scans were signifi cantly lower. More Australians reported intervening to reduce paediatric dose (95.7% vs 72.7%, P < 0.005), and 88.0% believed that over 60% of CT scans are justifi ed compared with 8.9% of Saudi participants. Conclusion: Australian and Saudi Arabian radiographers working in paediatric hospitals diff er in their knowledge bases. Knowledge can be improved through enhancement of hospital protocols and continuing education and training, and will lead to reduced radiation exposure among paediatric patients.
