Factors affecting radiographers' use of dose-reduction measures.

This study investigates radiographers' views on implementing dose-reduction measures, with a focus on verifying patient identity and pregnancy status, practising gonad shielding in men and using compression. An electronic questionnaire was distributed to radiographers working in general radiography and/or computed tomography. The questionnaire was based on factors from a framework for analysing risk and safety in clinical medicine. Ordered logistic regressions were used to analyse associations among factors and use of dose-reduction measures. In total, 466 questionnaires were distributed and 170 radiographers (36%) completed them. Clear instructions and routines, support from colleagues, knowledge and experience, a strong safety culture, managerial support and access to proper equipment influence the likelihood of using dose-reduction measures. The strongest associations were found between support from colleagues and verifying pregnancy status (OR = 5.65,P= 0.026), safety culture and use of gonad shielding (OR = 2.36,P= 0.042), and having enough time and use of compression (OR = 2.11,P= 0.003). A strong safety culture and a supportive work environment appears to be essential for the use of dose-reduction measures, and education, training and stress management can improve utilisation of dose-reduction measures.

Barriers to radiographers' use of radiation safety principles: A qualitative perspective.

INTRODUCTION: To minimise the risks associated with ionising radiation, it is necessary for all staff involved to employ specific techniques to reduce radiation exposure of the patient. These techniques include using compression during examinations of the pelvic region and lumbar spine, using a gonad shield, and asking women if they are pregnant. However, some staff do not use these techniques consistently. Increasing compliance requires determining why staff are non-compliant. Thus, this study aims to qualitatively investigate why radiographers do not use these techniques. METHODS: This qualitative study is based on a cross-sectional electronic survey with open-ended questions. The data were analysed using an inductive qualitative content analysis with quantification of the findings. In total, 111 radiographers from 20 hospitals in Sweden participated. RESULTS: Three categories appear related to barriers that could obstruct the radiographer from using compression, gonad shields and asking about pregnancy: patient characteristics, interaction between the patient and the radiographer and issues related to the situation and examination. CONCLUSIONS: The barriers to not using radiation protection measures varied depending on the specific measure. However, the barriers were mainly related to the patient experiencing pain, communication difficulties and cultural reasons. In addition, the lack of adequate and user-friendly equipment was seen as a barrier to applying compression and using gonad shielding.
