Summary
Discrepancies in combat casualty severity scores were found in one-third of cases when comparing the Military Abbreviated Injury Scale (mAIS) and the Military Combat Injury Scale (MCIS). These differences highlight potential variations in assessing injury severity in military settings.
Area of Science:
- Military Medicine
- Trauma Surgery
- Injury Scoring Systems
Background:
- Trauma scoring systems are crucial for assessing combat casualty severity.
- Specific systems like the Abbreviated Injury Scale 2005-Military (mAIS) and Military Combat Injury Scale (MCIS) are used in military settings.
- Understanding discrepancies between these systems is vital for accurate casualty management.
Purpose of the Study:
- To examine discrepancies in combat casualty severity scores between mAIS and MCIS.
- To review the literature on trauma scoring system application in the military.
- To compare the Military New Injury Severity Score (mNISS) and MCIS-New Injury Severity Score (MCIS-NISS).
Main Methods:
- A retrospective, cross-sectional study of 911 combat casualties from May 2005 to December 2014.
- Utilized the New Injury Severity Score (NISS) as a reference.
- Calculated severity using mAIS and MCIS, generating mNISS and MCIS-NISS.
Main Results:
- Explosion and gunshot wounds were predominant injury mechanisms.
- Overall mortality was 3.51%.
- Significant discordance (34.35%) was observed between mNISS and MCIS-NISS, particularly in survivors (P < .0001).
Conclusions:
- Discrepancies in injury severity levels between mNISS and MCIS-NISS affect approximately one in three combat casualties.
- These findings underscore the importance of considering potential variations in trauma scoring systems for military personnel.
- Further research may be needed to refine or standardize military trauma scoring.
