Unintended doses in radiotherapy-over, under and outside?

Area of Science:

• Medical Physics
• Radiation Oncology
• Healthcare Safety

Background:

• National reporting of serious incidents in radiotherapy is crucial for identifying potential harm and safety culture issues.
• Current UK guidance primarily addresses overexposures, but new legislation will encompass underexposures and positioning errors.

Purpose of the Study:

• To review current UK guidance on reporting serious incidents in radiotherapy.
• To propose practical approaches for addressing underexposures and positioning errors in incident reporting.
• To discuss the definition and implementation of a local error margin.

Main Methods:

• Review of existing UK radiotherapy safety guidance.
• Analysis of implications of new legislation regarding underexposures and positioning errors.
• Discussion of practical strategies for defining and applying local error margins.

Main Results:

• Radiotherapy is a safe treatment, but incident reporting is vital for continuous improvement.
• New legislation broadens the scope of reportable incidents to include underexposures and positioning errors.
• Practical approaches for defining local error margins are needed to manage these new categories.

Conclusions:

• Expanded incident reporting in radiotherapy enhances patient safety and safety culture.
• Clear definitions and practical application of error margins are essential for effective implementation of new guidance.
• Proactive management of radiotherapy incidents, including underexposures and positioning errors, is key to maintaining high safety standards.
