Summary
The ICD/AIS MAP effectively classifies pediatric injury severity, showing excellent agreement in Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS) for children across various ages and body regions.
Area of Science:
- Trauma research
- Medical informatics
- Pediatric emergency medicine
Background:
- Accurate injury severity classification is crucial for trauma care and research.
- Existing methods for classifying pediatric injury severity require validation.
- The ICD/AIS MAP offers a potential automated solution for injury coding.
Purpose of the Study:
- To evaluate the performance of the ICD/AIS MAP in classifying pediatric injury severity.
- To compare ICD/AIS MAP scores with existing trauma registry data for children.
Main Methods:
- Utilized data from Pennsylvania trauma centers (1994-1996) for children under 16.
- Converted ICD-9-CM codes to Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS) using the ICD/AIS MAP.
- Assessed agreement using weighted kappa and intraclass correlation coefficients.
Main Results:
- Excellent agreement was found for Injury Severity Scores (ISS), both overall and by severity level.
- Excellent agreement was observed for Abbreviated Injury Scale (AIS) scores across body regions and age groups.
- Agreement improved with age and was consistently high across all body regions.
Conclusions:
- The ICD/AIS MAP demonstrates excellent performance in assessing pediatric injury severity.
- Its accuracy in children is comparable to or exceeds performance in adult populations.
- The tool is reliable across the pediatric age spectrum and most body regions.
