Safety Considerations in Stereotactic Body Radiation Therapy

Area of Science:

• Radiation Oncology
• Medical Physics
• Patient Safety

Background:

• Stereotactic body radiation therapy (SBRT) involves high doses and short treatment courses, increasing complexity compared to conventional radiotherapy.
• SBRT relies heavily on imaging and presents unique technical and workflow challenges, potentially leading to a higher rate of errors.
• Errors in SBRT can have more significant consequences for patients due to the high doses and precise targeting involved.

Purpose of the Study:

• To identify and describe common error pathways in SBRT.
• To highlight the unique challenges and risks associated with SBRT quality and safety.
• To present established tools for mitigating SBRT errors and improving patient outcomes.

Main Methods:

• Review of SBRT error pathways.
• Analysis of case studies illustrating SBRT errors.
• Identification and description of 9 established quality and safety tools for SBRT.

Main Results:

• SBRT presents distinct challenges including high doses, reliance on imaging, and workflow differences.
• Errors in SBRT appear to occur at a higher rate and have a greater impact.
• Nine specific tools are identified to reduce SBRT errors or minimize their effects.

Conclusions:

• Systematic approaches are crucial for ensuring SBRT quality and safety.
• Understanding SBRT error pathways is key to developing effective safety strategies.
• Implementation of targeted tools can significantly enhance patient safety in SBRT treatments.
