Canadian Neurosurgery Educators' Views on Stereotactic Radiosurgery in Residency Training

Despite the increasing prominence of stereotactic radiosurgery (SRS) in treating intracranial and spinal pathologies, there is currently a dearth of exposure to this modality in the neurosurgical residency. To address this gap, the aim of this study is to assess neurosurgery educators' views regarding the current state of SRS exposure, and to identify potential approaches to improve residency education in this domain.

Qualitative thematic analysis and constructivist grounded theory methodology were employed. Semistructured telephone-based interviews were conducted with current or past residency program directors, as well as current departmental chairs across neurosurgical departments in Canada. Interviews were transcribed and subjected to thematic analysis using open and axial coding.

Of the 34 eligible participants, the overall response rate was 41.1% (14/34), with a 35.3% participation rate (12/34). Participants represented 9 of the 12 Canadian institutions surveyed. The majority of participants were current program directors (n = 8), followed by past program directors (n = 2), and departmental chairs (n = 2). Most respondents 75% (9/12) view an increasing role for SRS in neurosurgery. Unanimously, respondents endorse greater exposure to SRS during residency through formal residency rotations and engagement in interdisciplinary tumor boards to facilitate involvement in clinical decision-making.

This is the first study to systematically collate neurosurgery educators' views on SRS in residency in Canada and demonstrates recognition of the discordance between SRS in practice and residency training. Neurosurgery educators broadly endorse increased exposure to this modality. Future work is needed to delineate the requirements necessary to achieve adequate competency in SRS.
