Tourniquet use in the prehospital setting: Are they being used appropriately?

The objective of this study was to evaluate tourniquet use in the Hartford prehospital setting during a 34-month period after the Hartford Consensus was published, which encouraged increasing tourniquet use in light of military research.

This was a retrospective review of patients with bleeding from a serious extremity injury to determine appropriateness of tourniquet use or omission.

Level II trauma center between April 2014 and January 2017.

Eighty-four patients met inclusion criteria and were stratified based on tourniquet use during prehospital care.

Five of the 84 patients received a tourniquet. All five of those tourniquets (100 percent of the group, 6.0 percent of the population) were not indicated and deemed inappropriate. Three of the 84 patients did not receive a tourniquet when one was indicated (3.8 percent of the group, 3.6 percent of the population) and these omissions were also deemed inappropriate. Total error rate was 9.5 percent (8/84).

There was a significant association between Mangled Extremity Severity Score (MESS) and likelihood of requiring a tourniquet (p = 0.0013) but not between MESS and likelihood of receiving a tourniquet (p = 0.1055). There was also a significant association between wrongly placed tourniquets and the type of providers who placed them [first responders, p = 0.0029; Emergency Medicine Technicians (EMTs), p = 0.0001].

Tourniquets are being used inappropriately in the Hartford prehospital setting. Misuse is associated with both EMTs and first responders, highlighting the need for better training and more consistent protocols.
