About this trial
The PRE-hospital Cooling to improvE carDiac arrEst Neurological outComEs (PRECEDENCE) study is a pilot feasibility trial evaluating the implementation of pre-hospital targeted temperature management (TTM) using a wearable surface cooling device (CarbonCool® vest) in adult out-of-hospital cardiac arrest (OHCA) patients with return of spontaneous circulation (ROSC). The study aims to assess feasibility, fidelity, acceptability, and safety of initiating cooling in the field by emergency medical services (EMS) prior to hospital arrival. Results will inform the design of a larger definitive trial to determine the clinical effectiveness of early pre-hospital TTM in improving neurological outcomes.
