Development of a Core Critical Care Data Dictionary With Common Data Elements to Characterize Critical Illness and...

Area of Science:

• Critical care medicine
• Health informatics
• Data standardization

Background:

• Standardized data collection is crucial for critical care research and quality improvement.
• Existing data elements for critical illness and injuries lack uniformity, hindering analysis and collaboration.

Purpose of the Study:

• To develop the first core Critical Care Data Dictionary (C2D2).
• To establish a set of common data elements (CDEs) for characterizing critical illness and injuries.

Main Methods:

• A modified Delphi approach involving a multidisciplinary workgroup.
• Utilized electronic surveys and in-person meetings for consensus building.
• Iterative rounds of item generation, reduction, and refinement.

Main Results:

• The final C2D2 comprises 226 patient-level CDEs across nine domains.
• Key domains include ICU diagnoses, interventions, medications, and outcomes.
• 91% of the panel endorsed the C2D2 as a minimum viable data dictionary.

Conclusions:

• The C2D2 offers a foundation for enhanced critical care research, quality improvement, and clinical practice.
• Facilitates rapid data collection, analysis, and dissemination.
• Further validation in diverse critical care settings is recommended.
