This article compares competency-based and time-based education in neurosurgery, with special emphasis on the German model as a case study of CBE implementation.

Abstract

Modern neurosurgical training is evolving from traditional time-based models to competency-based training. This article explores the principles, strengths, and limitations of both approaches, using the Germany system as a model for competency-based neurosurgical training.

Introduction

Neurosurgical education has long relied on fixed durations and structured rotations. However, modern demands are steering programs toward competency-based education (CBE). Germany stands out in Europe for its structured yet flexible implementation of this model.

Time-Based Education in Neurosurgery

Show/Hide Details

✅ Strengths

  • Simple and standardized
  • Predictable for staffing and scheduling
  • Encourages peer relationships

⚠️ Weaknesses

  • Not tailored to learning speed
  • Risks passive progression
  • Emphasis on volume, not competence

Competency-Based Education (CBE): Key Principles

Germany’s Approach to Neurosurgical CBE

Germany’s shift to CBE encourages autonomy, adaptability, and personalized progression.

Comparative Analysis Table

Aspect Time-Based Model Competency-Based Model (Germany)
Duration Fixed (5 years) Variable (depends on competence)
Progression Calendar-based Skill-based
Assessment No Final board exam Continuous feedback & milestones
Flexibility Low High
Focus Quantity of cases Quality & autonomy
Trainee Empowerment Limited High

Implementation Challenges

Transitioning to CBE requires:

  1. Faculty training in assessment techniques
  2. Creation of valid tools for competency evaluation
  3. Institutional capacity for individualized progression
  4. National alignment and certification standards

Conclusion

CBE offers a promising alternative to traditional models, as seen in the German experience. It emphasizes mastery over time, allows individualized learning paths, and aligns better with the complexities of modern neurosurgical care. Future training models should consider integrating CBE elements to ensure high-quality, adaptive, and responsible neurosurgical education.

Limitations of the Spanish Neurosurgical Training Model

Spain follows a strict time-based model for neurosurgical training, with limited competency verification at the end of the residency.

  1. Training inequality across hospitals: Not all centers offer balanced exposure to all subspecialties.
  2. Risk of graduating underprepared residents: Without final objective evaluations or defined milestones.
  3. Lack of structured feedback: Assessments are informal and highly dependent on individual tutors.
  4. Demotivation for high-performing residents: No option to progress faster, even if exceeding expectations.
  5. Limited international recognition: The absence of final certification or competency exams hinders global mobility.

👉 In contrast, models like the German competency-based approach promote individual responsibility, learning autonomy, and ongoing real-world evaluation.

The Structural Crisis of Neurosurgical Training in Spain

Introduction

Neurosurgery is among the most demanding medical specialties, requiring not only technical excellence but deep clinical judgment, resilience, and lifelong learning. Yet, the Spanish system for training neurosurgeons remains entrenched in an obsolete, time-based model that fails to guarantee competency, consistency, or accountability. While other nations evolve toward rigorous competency-based frameworks, Spain’s system lags dangerously behind, raising ethical, clinical, and professional concerns.

Time-Based, Not Competency-Based

The foundation of neurosurgical training in Spain is a fixed-duration residency: five years, structured into predefined rotations (tumors, spine, vascular, pediatrics, etc.), typically without formal documentation of competency milestones. Progression is automatic, dictated by calendar time rather than demonstrated skill or readiness. There is no national final board exam. No procedural benchmarks. No standardized assessments of intraoperative decision-making or surgical autonomy.

Residents may complete their training without ever being formally evaluated on their capacity to independently perform critical neurosurgical procedures. The assumption that time served equates to competence is both scientifically unfounded and ethically indefensible.

Absence of National Oversight and Uniform Standards

Spain lacks a centralized national body that enforces minimum educational standards or audits training quality across hospitals. Each training center operates independently, with wide variability in surgical volume, faculty expertise, and subspecialty exposure. While some residents receive robust, well-supervised training, others operate in under-resourced departments where their learning is opportunistic and inconsistent.

There is no national logbook of surgical cases, no uniform curriculum, and no system to ensure that residents are exposed to the full spectrum of neurosurgical pathology. This results in profound inequality of training—one of the most corrosive features of the current model.

Unregulated Expansion of Training Centers

Perhaps most alarming is the fact that there is no national regulation governing how many hospitals may train neurosurgeons. The creation of new residency positions often depends solely on a department chief's request, without rigorous external review of case load, educational capacity, or subspecialty availability.

This leads to the accreditation of training programs in low-volume hospitals, some of which lack even the most basic infrastructure for neurosurgical education. The motivations behind these new positions are often more administrative or labor-related than educational. In effect, residency becomes a mechanism for staffing, not learning.

Culture of Complacency and Silence

Despite widespread awareness of these deficiencies among neurosurgeons and residents, few speak out. A culture of complacency, combined with fear of professional retaliation, preserves the status quo. Institutional inertia and bureaucratic complexity further block reform. There is no national forum for resident advocacy, no anonymous reporting system, and no incentives for transparency or innovation.

Consequences for Patients, Professionals, and the System

The risks of this training model are not theoretical—they are real. Undertrained neurosurgeons may be placed in high-responsibility roles without the skills or confidence to manage them. Patients may suffer the consequences of surgical inexperience, poor decision-making, or inadequate supervision. Meanwhile, capable residents are stifled by rigid structures that reward time over talent.

Internationally, Spain's standing in surgical education is eroding. Spanish-trained neurosurgeons often struggle to demonstrate equivalence when applying abroad. Conversely, foreign-trained specialists are met with bureaucratic resistance when attempting to integrate into the Spanish system, no matter how superior their background.

A Call to Radical Reform

Spain's neurosurgical training system does not need minor adjustments—it needs comprehensive reform. Essential measures include:

Conclusion

The current model of neurosurgical training in Spain is obsolete, fragmented, and dangerously permissive. It fails to protect patients, demotivates talent, and isolates Spain from international progress in surgical education. Radical change is no longer a matter of professional ambition—it is an ethical obligation.

Until this transformation occurs, every graduating neurosurgeon remains a product of a system that prioritizes duration over competence, bureaucracy over quality, and tradition over truth.
