The knowledge, awareness and practices of radiation safety amongst orthopaedic surgeons

BACKGROUND: Fluoroscopic imaging in orthopaedic theatres is increasing, with added risk to the orthopaedic surgeon who is increasingly being exposed to ionising radiation. It is thus crucial for orthopaedic surgeons to have a working knowledge of radiation safety. In spite of these concerns, however, many orthopaedic surgeons do not receive standard training in radiation safety. OBJECTIVES: The evaluation of orthopaedic surgeons’ knowledge, awareness and everyday practices regarding radiation safety in an academic hospital. METHODS: A questionnaire with multiple-choice-type questions was developed by a panel of experts and used to conduct a descriptive study. The questionnaire had multiple dimensions, each evaluating orthopaedic knowledge, awareness and practices, respectively. The study population included orthopaedic surgeons rotating within the orthopaedic circuit of the University of Pretoria. RESULTS: Orthopaedic surgeons regularly make use of fluoroscopic imaging in theatre, with 34 (77%) participants indicating that they use fluoroscopy in more than half of all their procedures performed. Most participants have insufficient knowledge of radiation safety, with the majority failing to correctly answer basic questions on radiation safety. Forty (91%) participants do not wear personal dosimeters, in spite of 39 participants (89%) believing that they are vulnerable to adverse effects. Basic radiation protection devices are underutilised, with 32 (73%) participants indicating that they have not received adequate training in radiation safety. CONCLUSION: The majority of orthopaedic surgeons regularly use fluoroscopic imaging in theatre yet lack in-depth knowledge and awareness regarding radiation safety associated with this imaging modality. Implementation of a radiation safety training programme is thus recommended.
