Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized clinical trial will determine if adult participants who are in the emergency department after being resuscitated from a cardiac arrest outside of the hospital benefit from care delivered at specialized centers.

The main question that it will answer is whether transferring participants to a hospital with a specialized cardiac arrest service improves recovery of function after 90 days.

Participants will receive all usual medical care, but some participants will be offered transfer to a regional cardiac arrest center and others will be offered care at the closest appropriate hospital. Investigators will interview participants after 90 days to assess their recovery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cardiac arrest is a sudden stopping of the heart, which can sometimes be reversed by rapid cardiopulmonary resuscitation (CPR) and emergency medical care. Each year, over 150,000 Americans are admitted to the hospital after receiving CPR. However, many of these patients die in the hospital. There is wide variation in patient outcomes between hospitals. A key knowledge gap about systems of care is whether specific hospital or subsequent interventions or processes of care are associated with better patient outcomes. Specifically, it is unknown if patient outcomes are improved by specialized centers or by improved implementation of recommended interventions at all hospitals.

Observational data in our region and internationally suggest that out-of-hospital cardiac arrest outcomes are better when patients who survive CPR are hospitalized in specialty care or high-volume centers. It is unclear from these studies what are the minimal capabilities that distinguish specialty care from usual care and which aspects of specialty care are influencing outcomes.

This trial will take advantage of a regional system of care that includes 18 hospitals in southwestern Pennsylvania that treat over 1,000 patients resuscitated from out-of-hospital cardiac arrest annually. This region includes one high-volume specialty center with specific attention to recommended interventions for this patient population, as well as several secondary and tertiary care facilities with variable resources and approaches to patient care. This randomized trial will compare outcomes for patients assigned to care at the specialty center versus other centers and will leverage the heterogeneity of treatment between centers to understand the influence of specific treatments.
