Physician Knowledge of Radiation Exposure and Risk in Medical Imaging

Area of Science:

• Medical Physics
• Radiology
• Healthcare Education

Background:

• Medical imaging is a significant source of radiation exposure for the public.
• Studies indicate a gap in healthcare providers' understanding of medical radiation risks.
• Diagnostic imaging knowledge is crucial for patient safety and effective care.

Purpose of the Study:

• To evaluate physicians' knowledge of radiation exposure and risk in diagnostic imaging across various specialties and training levels.
• To assess the impact of a brief educational presentation on improving physicians' understanding of radiation safety.

Main Methods:

• A pre- and post-presentation test was administered to 232 healthcare providers from multiple departments.
• The study was conducted at a large academic institution between 2014 and 2016.
• Tests assessed knowledge of radiation exposure and risk associated with different imaging modalities.

Main Results:

• Baseline knowledge of radiation exposure and risk was low, with 26% unable to identify ionizing radiation modalities.
• Post-presentation test scores significantly improved, indicating enhanced radiation safety knowledge.
• Radiologists had higher baseline scores but also showed improvement; other specialties had similar initial knowledge levels.

Conclusions:

• A brief educational intervention effectively improved physicians' understanding of medical radiation risks.
• There is a clear need to educate healthcare providers on radiation exposure to ensure informed decision-making in medical imaging.
• Improving provider knowledge supports high-quality, patient-centered care by optimizing the risk-benefit balance of imaging procedures.
