Area of Science:

  • Neurosurgery Workforce Development
  • Global Health Equity
  • Medical Education

Background:

  • A sustainable neurosurgery workforce requires understanding the global trainee landscape.
  • Previous data on the size and distribution of neurosurgery trainees worldwide is lacking.
  • Identifying training program characteristics and support is crucial for workforce planning.

Purpose of the Study:

  • To determine the number and distribution of global neurosurgery training programs and trainees.
  • To assess the support, diversity of experiences, and accreditation processes for neurosurgery trainees.
  • To analyze disparities in neurosurgery training resources based on country income and geographic region.

Main Methods:

  • A cross-sectional online survey was administered across 193 countries and 26 territories.
  • Participants were identified via neurosurgery societies, author contacts, and bibliometric searches.
  • Data were analyzed using population-weighted statistics, stratified by country income level and WHO regions.

Main Results:

  • An estimated 1261 neurosurgery training programs and 10,546 trainees were identified globally.
  • Trainee density was significantly higher in high-income countries (0.48/100,000) compared to low- and middle-income countries.
  • Low-income countries reported poorer access to subspecialty training and resources; accreditation was less common in LMICs.

Conclusions:

  • The global neurosurgery trainee workforce is estimated at 10,546 across 1261 programs.
  • Significant disparities exist in trainee density and resource availability between high-income and low-/middle-income countries.
  • Addressing these inequities is vital for a sustainable and globally representative neurosurgery workforce.
