Standardizing Tourniquet Reassessment and Conversion Across TCCC Tiers: TCCC Guidelines Proposed Change 25-2

Operational experience from the Russo-Ukrainian War revealed frequent use of tourniquets that were not medically indicated and an increase in ischemic complications from prolonged tourniquet application as a consequence of extended evacuation times. In response to this, the Committee on Tactical Combat Casualty Care (CoTCCC) convened a working group to evaluate whether tourniquet reassessment and conversion practices should extend to the All Service Member (ASM) level. With input from NATO and partner nations, the Working Group developed a standardized, time-based algorithm that provides plain language guidance for reassessment, repositioning, and conversion. The proposed change replaces the term replacement with repositioning, affirms a reassessment window within 2 hours for nonmedical personnel, and limits conversion beyond 2 hours to medical personnel. These updates will expand lifesaving capability to nonmedical responders, reduce preventable morbidity and mortality from tourniquet use, and align TCCC principles with current operational realities.
