NCT07304570

Brief Summary

The goal of this randomized controlled trial was to learn whether a hybrid telemedicine curriculum that combines virtual-reality (VR) simulation with interactive live-streamed neurosurgical cases improves neurosurgical intentionality and clinical decision-making in fourth-year medical students whose clerkships were disrupted by COVID-19. It also assessed technical skills, theoretical knowledge, and student experience. The main questions it aimed to answer were: Does the 4-week hybrid model (VR + live cases) produce greater gains in neurosurgical intentionality and decision-making than traditional online videos and readings? Does the hybrid model improve VR technical skill performance and student satisfaction without harming theoretical knowledge? Researchers randomized 112 students 1:1 to the hybrid intervention (15 h VR neuroanatomy/procedures + 20 h live-streamed surgeries/ICU rounds + real-time Q\&A) or a time-matched control group (pre-recorded videos, textbook readings, asynchronous forums). Participants in both groups: Completed 40 hours of remote content over 4 weeks Were tested at baseline and post-course on intentionality (modified Zwisch scale), decision-making (neurosurgery-specific SCT), 50-item MCQ knowledge, and VR proficiency metrics Joined focus groups and rated satisfaction on a 5-point Likert scale

Outcome Measures

Primary Outcomes (2)

  • Neurosurgical Intentionality

    Neurosurgical Intentionality: Intervention group post-intervention scores were compared with controls, the higer the score, the better the outcome

    4 weeks

  • Clinical decision-making score

    Clinical Decision-Making Score Range: 24-120 points (5-point Likert, 24 items) Levels: 24-48 = low 49-84 = moderate 85-120 = high The higher the score, the better the outcome

    4 weeks

Secondary Outcomes (3)

  • Theoretical Knowledge

    4 weeks

  • Technical Skill Performance score

    4 weeks

  • Student experience score

    4 weeks

Study Arms (2)

Intervention Group

EXPERIMENTAL
Other: VR Simulation (15 hours)+Live-Streamed Neurosurgical Procedures (20 hours)+Live-Streamed Neurocritical Care Rounds (5 hours)

Control group

NO INTERVENTION

* Pre-recorded neurosurgical videos (20 hours): Matched case types from the Neurosurgical Education and Training Resource (NETR) library, with voiceover but no interactivity. * Textbook/journal readings (15 hours): Chapters from Neurosurgery: The Essential Guide and articles from Journal of Neurosurgical Education (aligned with case content). * Asynchronous case discussions (5 hours): Text-based forums on the institution's LMS, moderated by faculty (48-hour response window).

Interventions

1. VR Simulation (15 hours): Customized modules on the NeuroVR Platform (validated for neurosurgical education): * Neuroanatomy (5 hours): 3D interactive models of cerebral cortex, brainstem, cranial nerves, and spinal cord (with vascular/meningeal overlays). * Procedural skills (10 hours): Craniotomy basics, ventriculostomy, lumbar puncture, and spine decompression-with real-time feedback on instrument handling and anatomical precision. 2. Live-Streamed Neurosurgical Procedures (20 hours): 18 diverse cases (brain tumor resection \[n=6\], spine fusion \[n=5\], aneurysm clipping \[n=3\], epilepsy surgery \[n=4\]) via HIPAA-compliant Zoom for Healthcare. Each session included: * Pre-procedure briefing (anatomical landmarks, surgical goals). * Intraoperative expert commentary (neurosurgeon + neuroanesthesiologist). * Real-time Q\&A (focused on neurocritical decision-making: e.g., "How do you adjust resection for eloquent cortex mapping?"). 3. Live-Streamed Neurocritical Care Rounds (5 hours): Week
