Generation of Interactive Knowledge Graphs to Enable Research of the Effects of Trauma Center Organization on Patient Outcomes.

This research addresses a knowledge gap on the effect of trauma center organization on patient outcomes. To allow trauma care stakeholders to explore data from their center and identify potential opportunities to improve patient outcomes by adjusting organizational patterns, we are creating knowledge graphs from data on relevant parameters. These include data on organizational parameters of trauma centers, currently an understudied topic, and patient outcome data. We have recruited 42 trauma centers in the US and have collected data from those sites. Our knowledge graph uses an ontology to aid knowledge collection and data integration across medical institutions. We are presenting a novel tool, the Knowledge Path Explorer, that allows users to query and expand the knowledge graph at their own pace and based on their needs. This paper presents the basics of the Knowledge Path Explorer, the extension of the underlying ontology to capture trauma patient outcomes, and the data curation process underlying the knowledge graph.
