Improving National Trauma Data Bank® coding data reliability for traumatic injury using a prospective systems...

Area of Science:

• Medical Informatics
• Trauma Surgery
• Health Services Research

Background:

• Trauma registries are crucial for research, quality improvement, and epidemiology in trauma care.
• Accurate data extraction from trauma registries is essential for optimal patient management.
• Current coding procedures may have limitations in diagnostic accuracy.

Purpose of the Study:

• To evaluate the accuracy of the Relational Trauma Scoring System™ for coding diagnoses.
• To compare the Relational Trauma Scoring System™ with the standard retrospective chart-based format.
• To identify methods for improving data accuracy in trauma registries.

Main Methods:

• 150 patient charts from a level I trauma service were abstracted.
• Charts were randomized and abstracted by trauma nurse clinicians using coding software.
• Coding accuracy was assessed before and after training on the Relational Trauma Scoring System™.

Main Results:

• Pre-training, trauma nurse clinicians achieved 52-64% accuracy; registrars scored 51%.
• Post-training, trauma nurse clinicians' accuracy increased to 80-86%.
• The Relational Trauma Scoring System™ demonstrated improved diagnostic coding accuracy.

Conclusions:

• Implementable changes can significantly enhance data accuracy from trauma centers.
• Training on the Relational Trauma Scoring System™ substantially improves coding performance.
• Optimized coding procedures are vital for reliable trauma registry data.
