A Single Institution Experience of a Biweekly Head and Neck Contouring Peer Review.

Abstract

Due to the complexity of head and neck radiotherapy, a single weekly chart rounds session is insufficient to review contours. A dedicated biweekly review of all head and neck contours (prior to treatment planning) that can fully assess images and targets can lead to better patient outcomes. A full review of all head and neck contours also increases the number of contours that resident physicians can observe. In total, 38 consecutive patients treated between August 2022 and December 2022 were analyzed in a biweekly head and neck contouring peer review. Three head and neck faculty radiation oncologists and four resident physicians participated. An allotted 30-minute time was granted per review session. Changes were tracked and stratified by whether physician contours underwent no changes/minor changes/major changes. Other metrics including re-irradiation status and attendance were noted. An average of 1.65 patients were discussed per review. Given the allotted time, on average this allowed for up to 18 minutes of discussion per patient. In contrast, our departmental chart rounds session is allotted 1 hour for 40+ patients to be discussed (1.5 minutes per patient). Overall, 10/38 patients underwent minor changes (26.3%) to contour structures and 1 patient underwent a major change (2.6%). Four patients (10.5%) were re-irradiation cases CONCLUSION: A dedicated biweekly half hour review session is both feasible and practical. Additional discussion of head and neck contours helps to implement improvements into a patient's treatment plan. Additional discussion and debate for primary and re-irradiation also increases the number of cases that a training resident physician can observe.
