The NTRR specifies a limited set of trauma core Common Data Elements (CDEs) highly recommended to be collected in all trauma studies that will be submitted to the National Trauma Research Repository (NTRR). The NTRR additionally specifies sets of basic CDEs in four environments of care: epidemiology, prehospital, acute hospital, and outcomes & rehabilitation, as well as CDEs related to social determinants of health (SDOH).
Investigators conducting studies relevant to any of these environments are strongly encouraged to select appropriate CDEs from the data dictionary to ensure that the data collected are standardized and interoperable across studies. Standardized data collection enables data sharing and cross-study secondary analyses.
