Radiation safety education for orthopaedic surgeons significantly improved attitudes and reduced radiation exposure and skin injuries over five years. These findings highlight the impact of targeted educational campaigns on occupational health.
Area of Science:
- Medical Imaging and Radiation Oncology
- Occupational Health and Safety
- Dermatology
Background:
- Occupational radiation exposure poses risks to healthcare professionals.
- Orthopaedic surgeons are particularly susceptible to radiation-induced skin injuries.
- The effectiveness of educational interventions in mitigating these risks requires evaluation.
Purpose of the Study:
- To assess the impact of a 5-year longitudinal educational campaign on orthopaedic surgeons' radiation exposure and skin health.
- To evaluate changes in radiation safety attitudes and practices.
- To determine if educational interventions can reduce the incidence of radiation-induced skin injuries.
Main Methods:
- A 5-year longitudinal study involving orthopaedic surgeons at Hirosaki University (2019-2024).
- Surveys collected self-reported weekly fluoroscopy (beam-on) time and dermatologist-graded hand skin findings.
- Educational campaigns focused on As Low As Reasonably Achievable principles and personal protective equipment were implemented from 2020-2023.
Main Results:
- Surgeon caution regarding radiation increased from 5.8% to 70.9%.
- Median weekly fluoroscopy time decreased from 9.5 to 8.0 minutes (p=0.045).
- Prevalence of radiation-induced skin injury declined from 34.9% to 25.6%.
Conclusions:
- Repeated radiation safety education was associated with improved surgeon attitudes, reduced self-reported fluoroscopy time, and better skin findings.
- The study suggests a link between educational activities, exposure, and skin health outcomes.
- Causality cannot be definitively established due to self-reported exposure and lack of a control group.
