A method for evaluating quality assurance needs in radiation therapy.

Area of Science:

• Medical Physics
• Radiation Oncology
• Quality Management

Background:

• Modern radiation therapy planning and delivery are increasingly complex.
• Traditional quality control and assurance programs struggle to keep pace with technological advancements.
• Existing quality management (QM) guidelines focus on equipment performance but need to adapt to new challenges.

Purpose of the Study:

• To address the need for a more effective QM framework in radiation therapy.
• To develop a systematic approach for prioritizing QM activities based on clinical impact and risk.
• To guide the allocation of resources for maximal benefit to patient care.

Main Methods:

• Developing a framework for designing QM activities based on risk assessment and failure modes.
• Utilizing failure mode and effect analysis (FMEA) to identify and evaluate potential errors.
• Presenting examples of FMEA application to intensity-modulated radiation therapy and high-dose-rate brachytherapy.

Main Results:

• A proposed framework for risk-based QM in radiation therapy.
• Guidelines for implementing QM programs that balance achievability and patient benefit.
• Demonstration of FMEA's utility in identifying potential failure modes in advanced radiotherapy techniques.

Conclusions:

• A risk assessment approach, particularly FMEA, is crucial for modern radiation therapy QM.
• This framework enables efficient resource allocation to enhance patient safety and treatment quality.
• The proposed approach offers a pathway for clinics to optimize their QM programs and guides future research.
