Quality Control of Radiation Delivery for Lower Gastrointestinal Cancers.

Abstract

Assessing the quality of health care delivered is a priority across medical specialties, but it is particularly critical for radiation oncology, a field with rapid introduction of new technologies and treatment paradigms. Deviation from acceptable standards can lead to delivery of inferior therapies and medical errors that can directly compromise patient clinical outcome, thus leading to disparities in quality of care. Professional oncologic specialty societies often take ownership of standardizing best practices by issuing evidence-based disease-specific consensus guidelines. They also inform quality indicators that are set as requirements for accreditation, maintenance of certification, and reimbursement. Cooperative groups also create benchmarks for quality radiation therapy through design of clinical protocols that set standard-of-care treatment practices. Pelvic radiotherapy for colorectal and anal cancers has undergone a significant transformation in radiation planning and delivery including increased complexity in contour segmentation with a transition from three-dimensional to intensity-modulated radiation therapy (IMRT). Compliance with quality metrics proposed in national consensus guidelines and participation in clinical trials help keep practicing radiation oncologists up-to-date with advances in our field and well-trained to provide safe and effective high-value care.
