Global Neurosurg Research Collaborative

Advancing neurological and neurosurgical practice worldwide through the coordination of multicentre research studies.

About GNS

Our Mission

Our mission is to improve global health outcomes by advancing neurological and neurosurgical practice worldwide.

Our Work

We conduct international, multicentre studies to answer clinically relevant research questions in neurological and neurosurgical disease. The global collaborative model enables us to:

  • Compare outcomes across countries
  • Investigate determinants of patient outcome
  • Assess areas of variability in neurological and neurosurgical practice
  • Highlight neurological and neurosurgical needs in developed vs developing countries
01

Global Scope

Studies are conducted in multiple countries; any neurology/neurosurgery center around the world can take part.

02

Clinically Relevant

Research questions that translate to better patient outcomes.

03

Collaborative Authorship

A collaborative authorship model recognizing contributions from all participating centers.

Determining the Global Outcomes of Traumatic Brain Injury in Low-, Middle- and High-Income Countries: A Multi-center, International, Prospective Cohort Study

Background

Every year, there are about sixty-nine million new cases of Traumatic Brain Injury (TBI) worldwide. However, there are wide variations in the management of TBI across low-, middle-, and high-income countries which affect TBI outcomes worldwide.

Study Design

A multicenter, international, prospective cohort study conducted within the period from June 1, 2019 to December 31, 2021. The follow-up duration for each patient is 90 days.

Eligibility

Any hospital receiving and managing TBI patients is eligible to participate. The minimum patient number per center is 12 patients per one team; all consecutive TBI cases must be included.

Team Structure

Each team (three people) selects a two-week period. Multiple teams in the same center can participate as long as they collect data in different 2-week periods.

Data Collection

Anonymous data on patient demographics, TBI etiology and severity, clinical and surgical management, and mortality rates. All data submitted to the secure RedCap system of the Brain Institute at Oregon Health and Science University, USA.
