To support the development of the National Trauma Research Repository (NTRR), a multidisciplinary workgroup used a consensus-driven approach to review established acute hospital-based trauma care data elements and recommend common data elements (CDEs) for inclusion in the NTRR data dictionary. A 14-member workgroup of military and civilian trauma researchers and data scientists located and reviewed databases, codebooks, data collection forms and published articles for trauma data elements relevant to the acute hospital-based trauma care environment. Identified data elements were reviewed in a three-round Delphi survey and monthly meetings with the workgroup were conducted. Consensus during the Delphi survey was defined by an 80% agreement threshold. 31 sources were reviewed for acute hospital-based trauma care data elements. After the three rounds and workgroup discussions, 62 elements (90%) reached consensus for inclusion, 2 elements (3%) were excluded, and 5 elements (7%) did not reach consensus. After final workgroup discussions, 61 elements were recommended for adoption in the NTRR The Delphi process proved effective in achieving expert consensus on data elements for acute hospital-based trauma care research. The resulting standardized CDEs will improve data harmonization and support consistent data collection in trauma research. These CDEs represent an initial framework and serve as a foundational starting point for acute hospital-based trauma care data collection within the NTRR. As researchers use the NTRR, the list of CDEs will grow and evolve to meet the needs of the trauma research community. VII.

Introduction: To support the development of the National Trauma Research Repository (NTRR), a multidisciplinary workgroup focused on prehospital trauma care used a consensus-driven approach to review established data elements and recommend basic common data elements (CDEs) for inclusion in the NTRR data dictionary. Methods: A 13-member workgroup of military and civilian trauma researchers and data scientists located and reviewed databases, codebooks, data collection forms, and published articles for data elements relevant to prehospital trauma care. Identified data elements were reviewed in a three-round Delphi survey and during monthly workgroup meetings. Consensus during the Delphi survey was determined with an 80% agreement threshold. Results: Twenty-one sources were reviewed for prehospital data elements. Following three rounds and workgroup discussions, 52 elements (84%) reached consensus for inclusion, two elements (3%) were excluded, and eight elements (13%) did not reach consensus. Discussion: The Delphi process proved effective in achieving expert consensus on basic CDEs for prehospital trauma care research. The resulting standardized basic CDEs will improve data harmonization and support consistent data collection in the NTRR. These CDEs represent an initial framework and serve as a foundational starting point for prehospital data collection within the NTRR. As researchers use the NTRR, the list of CDEs will grow and evolve to meet the needs of the trauma research community.

Introduction: To support the development of the National Trauma Research Repository (NTRR), a multidisciplinary workgroup used a consensus-driven approach to review established epidemiologic data elements and recommend basic common data elements (CDEs) for inclusion in the NTRR data dictionary. Methods: A 10-member workgroup of military and civilian trauma researchers and data scientists located and reviewed databases, codebooks, data collection forms, and published articles for data elements relevant to trauma epidemiology. Identified data elements were reviewed in a three-round Delphi survey, and monthly meetings with the workgroup were conducted. Consensus during the Delphi survey was analyzed with an 80% agreement threshold. Results: 13 sources were reviewed for epidemiology data elements. After the three survey rounds and workgroup discussions, 33 elements (80%) reached consensus for inclusion, 3 elements (7%) were excluded, and 5 elements (12%) did not reach consensus. Discussion: The Delphi process proved effective in achieving expert consensus on basic CDEs for trauma epidemiologic research. The resulting standardized basic CDEs will improve data harmonization and support consistent data collection in the NTRR. These CDEs represent an initial framework and serve as a foundational starting point for epidemiological data collection within the NTRR. As researchers use the NTRR, the list of CDEs will grow and evolve with the needs of the trauma research community. CDE standardization not only supports interoperable research but also enhances research quality, efficiency, and translation into clinical practice. Level of Evidence: Level VII
