  • Figure 3. City population
  • Most institutions have dedicated neuroICUs (78.2%) and neurointensivists cared for most of the patients (64.3%). Other practitioners that care for neuroICU patients include: PCCM (8.3%), anesthesiologists intensivists (4.2%), surgical intensivists (1.8%) and others (21.4%).
  • Research activities:
  • Even though majority of members are currently participating in clinical trials (66%), they are not members of any other research network (68%). However, 98% of members are willing to participate in clinical trials via NCRN and most of them (72%) already have full-time research coordinators.
  • The NCRN now includes a large number of centers from many countries.
  • This evolution into a large organized research infrastructure shows promise to be able to move the field of Neurocritical Care research forward.
  • NCRN is currently endorsing three Phase III clinical trials:
  • -ATACH II: funded by NINDS and currently actively enrolling.
  • -ALISAH II: submitted to NINDS for funding October 2011.
  • -TISH: currently under review by NINDS

  • The NCRN is a sub-committee of the Neurocritical Care Society committed to supporting and fostering the mission of the Society and is accountable to its Board of Directors.
  • The NCRN is composed of neurocritical care units and passionate neurointensivists who are motivated to carry out excellent clinical research in neurocritical care and to collaborate with colleagues around the world (1).
  • Mission
  • The mission of the NCRN will be to serve as a conduit for the design and execution of high quality, multi-center studies in the neurocritical care setting, intended to enhance the understanding of neurocritical care disorders and to improve outcome of the neurocritically ill patient. NCRN also will be committed to foster investigator-initiated collaborative studies and promote and promulgate neurocritical care research internationally.
  • Vision
  • To promote neurocritical care research.
  • To enhance and facilitate high-quality investigator-initiated studies.
  • To investigate clinically-relevant questions drawing from both bedside and laboratory observations.
  • To advance the understanding and development of research methods.
  • Core values
  • Collaboration and collegiality.
  • Innovation.
  • Promotion and development of scientific thought.
  • Integrity.
  • Accountability to our scientific community and our patients.


The NCRN was created in 2010 to further research endeavors in neurocritical care. In this report we update the NCS and show progress of the NCRN toward organizing the research infrastructure. We have abstracted data from the registration questionnaire that individuals or institutions are required to fill out when they request NCRN membership. Here we describe the number of participating sites along with their geographic location, and organization.


There were 170 registrations in the NCRN database as of September 18, 2011, with 154 confirmable active sites. The database includes sites from 23 countries. Nearly two thirds of sites are located in the US. Other countries include with number of sites: Canada 6, Germany 5, Argentina 5, Colombia 3, Holland 3, Brazil 3, Japan 2, Philippines 2, Switzerland (2) and several other countries with 1.

Most sites are located in large urban centers (72%), are academic centers (79%), have dedicated neuroICUs (79%), and have >500 hospital beds (62%) (Figures 1-3).
