Defining Representativeness Heuristic in Trauma Triage Data File

This is the data set used to define the representativeness heuristic in trauma triage. We performed a retrospective observational cohort study of moderate-to-severely injured patients who presented to non-trauma centers at UPMC from 2010-2014. We identified these patients using a validated algorithm to converted ICD-9 discharge codes into Abbreviated Injury Scale scores and Injury Severity Scores. We then abstracted initial encounter notes from the UPMC medical record for these patients and coded them for evidence of "representative" characteristics. We looked for differences in the presence of these characteristics by injury subgroups in between patients who were appropriately transferred to a trauma center and those who were not. We then performed a multi-variate logistic regression with random effects for hospital to identify the effect of having any representative characteristics at all on odds of transfer while adjusting for other covariates.
