Overview

Out-of-hospital cardiac arrest (OHCA) is a global public health issue. There is wide variation in both regional and inter-hospital survival rates from OHCA and overall survival remains poor at 7%. Regionalization of care into cardiac arrest centers (CAC) improves outcomes following cardiac arrest from ST elevation myocardial infarction (STEMI) through concentration of services and greater provider experience. The International Liaison Committee on Resuscitation (ILCOR) recommends delivery of all post-arrest patients to a CAC, but that randomized controlled trials are necessary in patients without ST elevation (STE). Following completion of a pilot randomized trial to assess safety and feasibility of conducting a large-scale randomized controlled trial in patients following OHCA of presumed cardiac cause without STE, we present the rationale and design of A Randomized tRial of Expedited transfer to a cardiac arrest center for non-ST elevation OHCA (ARREST). In total 860 patients will be enrolled and randomized (1:1) to expedited transfer to CAC (24/7 access to interventional cardiology facilities, cooling and goal-directed therapies) or to the current standard of care, which comprises delivery to the nearest emergency department. Primary outcome is 30-day all-cause mortality and secondary outcomes are 30-day and 3-month neurological status and 3, 6 and 12-month mortality. Patients will be followed up for one year after enrolment. Post-arrest care is time-critical, requires a multi-disciplinary approach and may be more optimally delivered in centers with greater provider experience. This trial would help to demonstrate if regionalization of post-arrest care to CACs reduces mortality in patients without STE, which could dramatically reshape emergency care provision.
