Abstract 12571: Social Network Analysis Demonstrating Impact of Resuscitation Outcome Consortium (ROC) on Collaboration
Introduction: National Institute of Health (NIH) funded ROC to create an infrastructure that would support clinical resuscitation research and facilitate collaboration among investigators from numerous institutions. While collaborations are key elements of scientific productivity, few have formally quantified collaboration over time. Social Network Analysis (SNA ) is widely used in social and clinical science to quantify and illustrate network relationships.We sought to characterize collaboration and cohesion amongst ROC investigators using (SNA) techniques.
Hypothesis: The number of collaborations between participating sites increased after the introduction of a clinical research consortium.
Methods: Lists of publications were abstracted from PubMed for investigators listed as contributing authors on at least one ROC publication. Publications were abstracted from two different time periods: 2003-2005 and 2013-2015 the time periods before the creation of ROC and after. The number of co-authorships was used to construct a matrix analyzed using UCINET Version 6.205 to calculate density as well as a network sociogram illustrating the collaborations. Density refers to the overall measure of interaction. Values range from 0-100, higher values indicate greater cohesion and collaboration between nodes (members) in a defined network.
Results: The network density was 1.4% in the time period before ROC and increased to 29.7%. In the pre-ROC period, there were 56 investigators within the 10 participating sites which grew to 126 investigators by 2015. In the pre-ROC epoch of time (3 years) there were 418 total publications which increased to 1,558 by the 2013-2015 epoch.
Conclusions: ROC helped facilitate collaboration resulting in an increase in both co-authored publications and network density that might not have existed without ROC. It also created a framework for interaction amongst investigators with shared clinical interests across multiple institutions.
