The neurosurgical curriculum: Which procedures are essential?

Abstract

Objective: Traditionally, neurosurgery is a competitive field. Throughout the years, the surgical armamentarium has been subject to change, e.g. due to the rise of indications for gamma knife, functional or endovascular surgery. Furthermore, due to modern day issues among residents, such as work hour restrictions (WHRs) and prevalence of burn-out, may require contemporary modifications of the neurosurgical curriculum. By the means of this cross sectional research, the current curriculum is evaluated. Methods: In September 2019, a 21-question survey was mailed to members of the Congress of Neurological Surgeons using SurveyMonkey. The survey consisted out of 3 parts: demographics of the respondents, respondent‘s neurosurgical residency and opinions on essential procedures. Results: After the two reminders, 578 members responded resulting in a response rate of 7.3%. Respondents had a mean residency program of 7 years (range 3 to 12 years). Of the residents, 87.5% had a weekly WHR of 80 h per week. A minority (43.8%) felt WHRs would limit the chances of residents to master surgical techniques.Neurotraumatical procedures such as decompression of subdural (91.5%) and epidural (91.3%) hematoma‘s, ventriculoperitoneal shunt insertion (86.9%), Chiari decompression (81.4%) and cervical discectomy (81.4%) were the procedures respondents mastered the most. This in contrast to endovascular procedures (67.9%), percutaneous endoscopic lumbar discectomy (48.5%) and deep brain stimulation (34%), in which respondents were less proficient. Conclusions: The current study gives an evaluation of different neurosurgical curricula and aimed to identify which surgical procedures are deemed as essential by neurosurgeons worldwide. Functional neurosurgery is the field in which most neurosurgeons required more instruction. Neuroendovascular and Gamma knife surgery were subspecializations in which neurosurgeons were less proficient but also specializations that were deemed more desirable to be known during residency.
