Task Analysis Tool to Evaluate Tactical Combat Casualty Care in the Extreme Cold

Area of Science:

• Military Medicine
• Environmental Physiology
• Medical Device Development

Background:

• Growing geopolitical interest in the Arctic necessitates specialized military medical protocols.
• Current Tactical Combat Casualty Care (TCCC) is based on data from temperate climates, not extreme cold.
• Unique environmental factors in cold regions impact casualty care effectiveness.

Purpose of the Study:

• To develop and evaluate a tool for assessing TCCC protocols in extreme cold environments.
• To identify specific challenges in applying TCCC in sub-zero temperatures.
• To provide a standardized method for evaluating TCCC effectiveness in the Arctic.

Main Methods:

• Development of the Task Step Analysis Tool-Binary (TSAT-B).
• Pilot testing of TSAT-B using a trauma manikin in Alaskan field environments (-2 to -35°C).
• Task steps categorized (provider, casualty, procedure), timed, with hand temperature measured; binary go/no-go feedback utilized.

Main Results:

• The TSAT-B demonstrated utility in evaluating TCCC tasks under extreme cold conditions.
• Data collected provides insights into the impact of cold on medical task performance.
• The tool successfully captured performance metrics relevant to cold-weather TCCC.

Conclusions:

• The TSAT-B is a valuable tool for assessing the efficacy of TCCC in extreme cold.
• Standardized evaluation using TSAT-B can improve TCCC protocols for Arctic operations.
• The tool supports the adaptation of TCCC for near-peer geopolitical challenges in cold regions.
