Potential risk assessment: a model for quality evaluation in fluoroscopy-guided interventional procedures

Area of Science:

• Medical Imaging
• Radiology
• Radiation Safety

Background:

• Interventional radiology procedures involve significant radiation exposure.
• Effective risk assessment and safety monitoring are crucial in these settings.
• Existing models may not comprehensively address both patient and occupational doses.

Purpose of the Study:

• To introduce and evaluate a novel model for potential risk assessment (MARP) in interventional radiology.
• To establish a system for monitoring patient and occupational radiation doses.
• To enhance safety protocols in fluoroscopy procedures.

Main Methods:

• Development of the Model for Potential Risk Assessment (MARP) with a 0-5 indicator scale.
• Categorization of radiation levels by gender, procedure type, Kerma air product (Pka), and accumulated dose (mGy).
• Application of the MARP model across 121 institutions over 8 years, collecting data on 201,656 patient doses and 8,007 occupational doses.

Main Results:

• The MARP model was successfully implemented in numerous institutions, gathering extensive radiation dose data.
• Detailed records of both patient (average 22,406/year) and occupational (average 890/year) radiation doses were collected.
• The study demonstrated a viable strategy for quality evaluation in fluoroscopy.

Conclusions:

• The MARP model provides a robust framework for potential risk assessment in interventional radiology.
• Implementation of a compulsory information system is effective for monitoring radiation safety.
• This approach contributes to improved quality evaluation and safety in fluoroscopic procedures.
