Dear Global Neurosurg Team,

Many thanks again for joining the Global Neurosurg Research Collaborative. We look forward to the participation of your center in the GNS international multicentre research network.

COVID-19 update

We are aware that neurosurgical operations as well as the GNS data collection process have been affected by the current COVID-19 pandemic. Collaborator teams whose data collection period was interrupted by the pandemic can participate through an alternative two-weeks period of their choice, once the conditions improve and it becomes possible to participate.

Study Documents

For the GNS-I study, all documents are downloadable from the GNS website here:

RedCap Update

We have re-structured the RedCap database to enhance patient privacy. Each user will now only be able to view the records that correlate to their own institution. If you see many fewer records the next time you log in to enter data, this is why. Larger limited data sets that include data from all sites are still available upon request, but you will only be able to independently pull reports from records associated with your own site.


All investigators who participate in the GNS-1 study will get PubMed-citable co-authorship in the publication(s) that arise from this project.
