Neurosurgery is a demanding specialty, and a trainee’s exposure to its tenets is usually achieved through residency. Medical students only access neurosurgical knowledge via brief stints in clerkships/electives and often lack mentorship and early exposure. This study sought to investigate the varying expectations about neurosurgical training held by Canadian medical students, with the goal of determining the impact of early exposure through educational opportunities and mentorship in developing interest and familiarity in the field.

A cross-sectional study across Canada was conducted where students were provided with a 35-point questionnaire pertaining to mentorship, educational opportunities and interests regarding neurosurgery through REDcap. Questions were open-ended, closed-ended (single choice) or five-point Likert scale (matrix format). Interest in pursuing neurosurgery was selected as the primary outcome of this study and was dichotomized into high or low interest. Predictors of interest were determined using multivariable logistic regressions.

A total of 136 students from 14 accredited Canadian medical schools responded to the study. Most (55.9%) had prior exposure, and the most commonly reported deterring factors were work–life balance (94.5%) and family (84.6%). Predictors of interest included participation in relevant case-based discussion (OR = 2.644, 95% CI [1.221–5.847], p = 0.015) and involvement in neurosurgical research encouraged by home institution (OR = 1.619, 95% CI [1.124–2.396], p = 0.012).

Future efforts to improve student interest should focus on early exposure to the field such as developing pre-clerkship neurosurgical electives or medical student groups focused on neurosurgery.

Functional MRI (fMRI) has proven valuable in presurgical planning for people with brain tumors. However, it is underutilized for patients with epilepsy, likely due to less data on its added clinical value in this population. We reviewed clinical fMRI referrals at the QEII Health Sciences Center (Halifax, Nova Scotia) to determine the impact of fMRI on surgical planning for patients with epilepsy. We focused on reasons for fMRI referrals, findings and clinical decisions based on fMRI findings, as well as postoperative cognitive outcomes.

We conducted a retrospective chart review of patients who underwent fMRI between June 2015 and March 2021.

Language lateralization represented the primary indication for fMRI (100%), with 7.7% of patients also referred for motor and sensory mapping. Language dominance on the side of resection was observed in 12.8% of patients; in 20.5%, activation was adjacent to the proposed resection site. In 18% of patients, fMRI provided an indication for further invasive testing due to the risk of significant cognitive morbidity (e.g., anterograde amnesia). Further invasive testing was avoided based on fMRI findings in 69.2% of patients. Cognitive outcomes based on combined neuropsychological findings and fMRI-determined language dominance were variable.

fMRI in epilepsy was most often required to identify hemispheric language dominance. Although fMRI-determined language dominance was not directly predictive of cognitive outcomes, it helped identify patients at low risk of catastrophic cognitive morbidity and those at high risk who required additional invasive testing.

Many Royal College of Physicians and Surgeons of Canada (RCPSC) graduates in neurosurgery face significant challenges in finding full-time employment. The current study describes the career outcomes of neurosurgery residents from Canadian programs.

All RCPSC neurosurgery graduates (n = 106) who completed their residency between 2015 and 2020 were included in this study. Baseline characteristics were determined for the entire cohort and then stratified by employment status. Several logistic regression models were used to identify predictors of full-time employment after residency.

Overall, 26.4% of neurosurgery graduates from 2015 to 2020 have been underemployed, defined as locum and clinical associate positions (6.6%), the pursuit of multiple fellowships (16%) and career change/nonsurgical career (3.8%). Only 52.0% of graduates were fully employed in Canada, with 30.2% appointed at academic institutions. Skull-base/open vascular (OR: 0.055, 95%CI [<0.01, 0.74]) and general neurosurgery (OR: 0.027, 95% CI [<0.01, 0.61]) fellowships were associated with underemployment. Advanced research degrees (master’s or Ph.D.) and sex were not associated with full-time employment.

Over one-quarter of recent Canadian neurosurgery graduates were underemployed, and nearly half do not find employment in Canada. These results reflect a concerning reality for current and prospective neurosurgery graduates in Canada and will hopefully serve as a call to action for the Canadian neurosurgery community.

Meningiomas are common brain neoplasms that can significantly influence health-related quality of life (HRQOL), yet the factors influencing HRQOL in adult patients remain unclear. We aimed to bridge this knowledge gap by determining these key factors.

We conducted a systematic review, searching EMBASE, MEDLINE, CINAHL, Scopus and PsycINFO up to February 2024. We included original, peer-reviewed studies focusing on adult patients (>18 years) with current or past meningioma at any stage of treatment that measured HRQOL or its proxies in relation to patient-, tumour- and treatment-related factors. Two independent reviewers screened abstracts and full-texts, selecting studies with an acceptable risk of bias for data extraction and narrative synthesis. The protocol of this review was registered on PROSPERO (# CRD42023431097).

Of N = 3002 studies identified, N = 31 studies were included. Key factors found to influence HRQOL in adult meningioma patients include surgery, radiotherapy, neurological function, functional status, comorbidities, sleep quality, psychological impairment, age and employment. Factors related to tumour characteristics yielded inconsistent findings. Heterogeneity and inconsistencies in HRQOL measurement across studies hindered definitive conclusions about the impact of factors on HRQOL.

Our review elucidates the multifaceted influences on HRQOL in meningioma patients, with significant variability due to patient-, tumour- and treatment-related factors. We emphasize the need for standardized, disease-specific HRQOL assessments in meningioma patients. Collaborative efforts towards consistent, large-scale, prospective research are essential to comprehensively understand and improve HRQOL, thereby enhancing tailored care for this population.

Operative cancellations adversely affect patient health and impose resource strain on the healthcare system. Here, our objective was to describe neurosurgical cancellations at five Canadian academic institutions.

The Canadian Neurosurgery Research Collaborative performed a retrospective cohort study capturing neurosurgical procedure cancellation data at five Canadian academic centres, during the period between January 1, 2014 and December 31, 2018. Demographics, procedure type, reason for cancellation, admission status and case acuity were collected. Cancellation rates were compared on the basis of demographic data, procedural data and between centres.

Overall, 7,734 cancellations were captured across five sites. Mean age of the aggregate cohort was 57.1 ± 17.2 years. The overall procedure cancellation rate was 18.2%. The five-year neurosurgical operative cancellation rate differed between Centre 1 and 2 (Centre 1: 25.9%; Centre 2: 13.0%, p = 0.008). Female patients less frequently experienced procedural cancellation. Elective, outpatient and spine procedures were more often cancelled. Reasons for cancellation included surgeon-related factors (28.2%), cancellation for a higher acuity case (23.9%), patient condition (17.2%), other factors (17.0%), resource availability (7.0%), operating room running late (6.4%) and anaesthesia-related (0.3%). When clustered, the reason for cancellation was patient-related in 17.2%, staffing-related in 28.5% and operational or resource-related in 54.3% of cases.

Neurosurgical operative cancellations were common and most often related to operational or resource-related factors. Elective, outpatient and spine procedures were more often cancelled. These findings highlight areas for optimizing efficiency and targeted quality improvement initiatives.

Traumatic spinal cord injuries (tSCI) are common, often leaving patients irreparably debilitated. Therefore, novel strategies such as nerve transfers (NT) are needed for mitigating secondary SCI damage and improving function. Although different tSCI NT options exist, little is known about the epidemiological and injury-related aspects of this patient population. Here, we report such characteristics to better identify and understand the number and types of tSCI individuals who may benefit from NTs.

Two peripheral nerve experts independently evaluated all adult tSCI individuals < 80 years old admitted with cervical tSCI (C1–T1) between 2005 and 2019 with documented tSCI severity using the ASIA Impairment Scale for suitability for NT (nerve donor with MRC strength ≥ 4/5 and recipient ≤ 2/5). Demographic, traumatic injury, and neurological injury variables were collected and analyzed.

A total of 709 tSCI individuals were identified with 224 (32%) who met the selection criteria for participation based on their tSCI level (C1–T1). Of these, 108 (15% of all tSCIs and 48% of all cervical tSCIs) were deemed to be appropriate NT candidates. Due to recovery, 6 NT candidates initially deem appropriate no longer qualified by their last follow-up. Conversely, 19 individuals not initially considered appropriate then become eligible by their last follow-up.

We found that a large proportion of individuals with cervical tSCI could potentially benefit from NTs. To our knowledge, this is the first study to detail the number of tSCI individuals that may qualify for NT from a large prospective database.
