A national study of neurosurgical residency competency development

In a retrospective observational cohort study Using national milestone data from 2478 neurosurgery residents across 120 U.S. programs (2018–2022), with descriptive statistical analysis Khalid et al.evaluate the progression of neurosurgical residents across the 6 ACGME core competencies and 20 subcompetencies, specifically: Assessing how many residents reach level 4 proficiency by the final year (PGY-7). Identifying patterns of co-occurring deficiencies in competencies. They conclude that neurosurgery residents demonstrate substantial milestone progression throughout training, but gaps remain—particularly in specialized clinical skills and self-assessment (Reflective Practice). Nearly 45% fail to reach level 4 in at least one subcompetency by PGY-7. These deficiencies are concentrated in areas often covered during fellowship training (e.g., epilepsy, pain, peripheral nerve). Therefore, residency programs may need to enhance exposure to these areas or redefine competency expectations. The authors recommend: Targeted educational interventions

Specialized procedural training To ensure that all residents achieve the necessary competencies for independent practice 1)


This study mistakes numerical progression in a checklist for actual neurosurgical maturity. “Milestones” are treated as objective truths, when in reality they are administrative fictions imposed top-down by ACGME to simulate accountability. The implicit assumption—that every resident must hit an arbitrary “level 4” to be considered competent—is never questioned. The authors do not interrogate what level 4 means, who defines it, or whether it maps to meaningful clinical outcomes. Instead, they deliver descriptive statistics masquerading as insights.

Post-traumatic hydrocephalus after decompressive craniectomy: a multidimensional analysis of clinical, radiological, and surgical risk factors

In a retrospective observational cohort study Romualdo et al. from the Department of Neurosurgery Faculty of Medicine, Technische Universität Dresden University Hospital Carl Gustav Carus published in the Neurosurgical Review to identify clinical, radiological, and surgical risk factors associated with the development of shunt-dependent posttraumatic hydrocephalus (PTH) in patients who underwent decompressive craniectomy following severe traumatic brain injury (TBI). Shunt-dependent post-traumatic hydrocephalus (PTH) occurred in 27% of patients after decompressive craniectomy for severe TBI. Independent risk factors included older age, basal cistern subarachnoid hemorrhage, post-traumatic ischemic infarcts, transcalvarial herniation, subdural hygroma, and progressive contusion hemorrhages. Surgical parameters were not predictive. Patients requiring shunt placement had significantly worse neurological outcomes 5).


🚨 The Illusion of Multidimensionality Despite claiming a “multidimensional” analysis, the study delivers a monotonous list of obvious associations—many of which have been reported in the literature for over a decade. Subarachnoid hemorrhage, infarction, hygroma, contusion progression… yes, thank you, we knew that. What’s new? Almost nothing.
