Online Adaptive Radiotherapy

Online adaptive radiotherapy (oART) is a cutting-edge radiation therapy technique that addresses anatomical changes during a course of treatment. Its core concept involves using on-board imaging, such as cone-beam CT (CBCT), to assess the patient's current anatomy immediately before each treatment session. A new treatment plan is then generated or adapted 'online' within minutes to account for tumor shrinkage or organ motion. Within an enterprise risk management framework, oART is a high-complexity, high-risk process. Its implementation must adhere to standards like **ISO 14971:2019 (Medical devices — Application of risk management)**, which mandates systematic identification, evaluation, and control of potential hazards like imaging artifacts, software errors, or human factors to ensure patient safety and treatment quality. It differs from offline ART, where plan adaptations take days and cannot respond to daily variations.

In a healthcare provider's ERM, applying oART involves rigorous operational risk control. Key implementation steps include: 1. **Risk Identification & Analysis**: Following the **IEC 60812 (Failure modes and effects analysis - FMEA)** standard, a cross-functional team (physicists, physicians, therapists) maps the oART workflow to identify potential failure modes, such as incorrect contouring or software crashes, and assesses their risk priority. 2. **Risk Control & Mitigation**: For high-risk items, specific controls are designed. This includes implementing standard operating procedures (SOPs) for dual-person verification of contours and developing robust fallback plans to ensure patient safety if the automated workflow fails. 3. **Monitoring & Review**: Key Risk Indicators (KRIs), such as 'frequency of adaptation time exceeding threshold' or 'QA failure rates,' are established and monitored. Regular reviews of incident reports and KRI data help continuously improve the process, leading to measurable outcomes like a reduction in treatment delivery errors and enhanced compliance with regulatory audits.

Taiwanese healthcare institutions face three main challenges when implementing oART: 1. **High Costs and Resource Constraints**: The substantial initial investment and ongoing maintenance costs for oART systems pose a significant financial barrier. The solution involves conducting a thorough cost-benefit analysis and exploring phased implementation or regional alliances to share costs. 2. **Interdisciplinary Talent Gap**: Effective oART operation requires seamless collaboration among physicists, oncologists, and IT staff, but professionals with such integrated skills are scarce. Mitigation strategies include establishing robust in-house training programs in partnership with vendors and academic institutions. 3. **Evolving Regulatory and QA Standards**: The quality assurance (QA) protocols for this new technology are complex, and national standards from regulators like the Taiwan FDA (TFDA) are still developing. The priority is to proactively adopt international best practices (e.g., AAPM guidelines) to build a rigorous internal QA system that exceeds current regulatory requirements.
