The ProfessionDetermining an Imaging Literacy Curriculum for Radiation Oncologists: An International Delphi Study
Introduction
Medical imaging plays a fundamental role in the practice of radiation oncology (RO). It is critical for accurate staging, target and organ-at-risk delineation, and image guidance for radiation treatment. Technological advances in imaging science have always provoked radical changes in nearly every aspect of RO 1, 2, 3. Radiation oncologists currently have new imaging techniques and tools at their disposal that combine anatomic and functional imaging for staging, planning, treatment delivery, and follow-up (4). Advances in imaging have allowed for more conformal radiation treatments and have facilitated dose escalation while maintaining a favorable impact on normal tissue tolerances (5). The effective use of multiple imaging modalities has resulted in significant improvements in patient outcomes 6, 7.
New knowledge, skills, and attitudes are needed to optimize the application of medical imaging in modern RO practice (8). Elsewhere, we define “imaging literacy” in RO as being competent in a diverse set of skills including image acquisition, image optimization, and application to patient specific situations (9). While some residency programs are beginning to understand the need for including comprehensive imaging components in their curricula 10, 11, there are no accepted competency profiles that fully address the training needs of RO residents and practicing physicians (12). A review of international requirements for RO 13, 14, 15, along with a review of published literature 16, 17, 18, further emphasizes a widening gap between the need for updated imaging competency among radiation oncologists and the lack of appropriate educational guidelines.
The CanMEDS medical education framework defines the national postgraduate medical education standards in Canada (19). This framework articulates an educational taxonomy of competency groupings that, taken together, guide the essential abilities that physicians require (20). Individual competency items are formed from the best available evidence. These essential “key” competencies are broad abilities that form the grounding on which program-level objectives may be built. Subordinate abilities, referred to as “enabling” competencies, are the specific “ingredient” abilities (knowledge, skills, and attitudes) required to attain each key competency. The viability of any new competency framework depends on the completeness, accuracy, and applicability of both key and enabling competencies to the practice setting. The purpose of this study was to develop a viable entry-to-practice competency profile in imaging literacy for RO based on international consensus.

Competency list generation
From September 2012 to December 2012, a review of the published literature, published objectives of training, and program-specific curricula was conducted to generate an inclusive preliminary list of potential imaging competency items. Most of these sources were readily available to investigators through academic departments or online through professional organizations such as the Royal College of Physicians and Surgeons of Canada and the American Board of Radiology. Permission was requested
Competency list refinement
An initial list of 263 potential enabling competency items was compiled from 14 sources including University of Toronto, Department of Radiation Oncology Medical Physics Residency Program (24); imaging sub-module, Ryerson University Introduction to Imaging Course (25); Royal College of Physicians and Surgeons of Canada Objective of Training for Radiation Oncology (26); Royal Australian and New Zealand College of Radiologists (13); Royal College of Physicians and Surgeons of Canada, Objective of
Discussion
The practice of RO is changing. Advances in imaging technology have impacted all aspects of RO practice including diagnosis, treatment planning, treatment delivery, and follow-up. These changes have improved clinical outcomes and have facilitated the use of new techniques such as stereotactic body radiation therapy 3, 33. RO training programs have struggled to keep curricular content relevant for modern clinical practice (12). This is in part due to a lack of consensus guidelines on the level
Conclusions
The competency profile described in this study represents an international consensus on the items which can inform RO training requirements. Future work should address novel methods to deliver and assess these competencies.

Postgraduate Global Health Competency Profile for Radiation Oncology
2018, Clinical OncologyCitation Excerpt :In our study, items voted to be included by >75% of phase 2 participants were included in the final profile. This is consistent with previous studies [19,21]. The final competency items were aggregated and refined by investigators and placed into the seven CanMEDS categories of key competencies: (1) professional; (2) communicator; (3) collaborator; (4) leader; (5) health advocate; (6) scholar; and (7) medical expert, to generate a final competency profile structure.

The field of radiation therapy is expected to continue to evolve [16], and training programs for radiation oncologists, physicists, and RTT must evolve to keep pace of clinical practice [17]. As image guidance technology impacts all disciplines in radiation medicine, the module's applicability to radiation oncology and physics was explored in this investigation [10].
Development of a Quality and Safety Competency Curriculum for Radiation Oncology Residency: An International Delphi Study
2017, International Journal of Radiation Oncology Biology PhysicsCitation Excerpt :Items ranked for inclusion by ≥75% of participants were included in the final competency profile, and the remaining items were excluded. This criterion is consistent with previous studies (20, 21). The final competency profile structure was derived by organizing all the competency items ranked for inclusion into thematic groups under headings adapted from Deming's System of Profound Knowledge (22): Appreciation for a System, Knowledge of Variation, Theory of Knowledge, Psychology, and Safety.
