Radiographers' role in justification of medical imaging examinations.

INTRODUCTION:Justification is one of the fundamental principles in radiation protection and according to the ICRP, justification means that any decision that alters the radiation exposure situation should do more good than harm. The purpose of this study was to explore diagnostic radiographers' attitude towards their role in justification, and to assess the perceived need for justification discussions with peers and the ability to reject unjustified referrals during day, evening, and night shifts. METHODS:This study was conducted in Norway and Denmark. A questionnaire was developed in Norwegian and translated into Danish, and two experienced radiographers assessed content validity. A secure online data capture solution was used, and the questionnaire was distributed to radiographers working in clinical settings in March and April 2022 (n = 1215). RESULTS:A total of 202 radiographers were included in the study, 93 from Norway and 109 from Denmark, respectively. Seventy-nine per cent of the radiographers reported that they had a duty to assess justification and 86 % did so daily. Their role in justification assessment was reported as relatively important, where CT and MRI had significantly different results than the total respondents. Radiologists were designated as being most responsible in the assessment, closely followed by referring doctors and radiographers. The most important criterion for justification assessment was the referring doctor's clinical assessment. The need to confer was highest during daytime when there were also more opportunities to confer. CONCLUSION:The need to discuss justification of examinations is greater during daytime when access to radiologists is also high, while both access and need are low during night shifts. Further research is needed to explain the latter finding. Radiographers who engage in daily justification assessments, and perceive it as a duty, find justification important and report having sufficient knowledge to carry out these assessments.
