In-hospital cardiac arrests are a common and lethal problem, accounting for approximately 160,000 deaths every year in the United States. Previous efforts to improve cardiac arrest outcomes have largely focused on pre-arrest (e.g., rapid response teams) and intra-arrest factors (e.g., quality of cardiopulmonary resuscitation [CPR]); much less emphasis has been placed on post-arrest factors or post-resuscitation care. Yet, nearly 50% of all deaths due to a cardiac arrest occur during the post-resuscitation phase and there is widespread belief that survival can be improved substantially. The importance of the post-resuscitation phase has been recently recognized by professional societies like the American Heart Association. However, our understanding of the critical elements of post-resuscitation care that might improve patient outcomes remains severely limited; we do not understand precisely which therapies, protocols and organizational factors are effective. The research proposed in this application has been designed to advance the science and knowledge regarding post- resuscitation care as well as support the continued development of Dr. Saket Girotra- an extremely promising cardiologist with interest and training in health services research.
Aim 1 will involve a systematic review of the existing literature to comprehensively synthesize all interventions (therapies, processes of care, organizational interventions) that have been studied for improving survival during the post-resuscitation phase. The available evidence will be systematically synthesized using both qualitative and quantitative (e.g., meta-analysis) methods.
Aim 2 will examine hospital-level variation in post-resuscitation survival using data from the Get With The Guidelines-Resuscitation (GWTG-Resuscitation) registry. Using hierarchical models, we will estimate risk- adjusted rates of post-resuscitation survival at each hospital. We will identify hospitals with exceptionally good survival rates (high-performing hospitals) using a deviance approach. This work will lay the foundation of our efforts to identify specific practices at high-performing hospitals that allow them to achieve superior outcomes.
Aim 3 will involve development and implementation of a survey of key informants at participating hospitals in GWTG-Resuscitation to obtain detailed information regarding hospital-specific post-resuscitation care practices. The survey will allow us to identify which specific strategies are used by high performing hospitals that allow them to achieve their exceptional outcomes. We hypothesize that these strategies will be multi- faceted and include specific treatments, processes of care, personnel, as well as organizational factors (e.g., leadership, communication). Identifying strategies that are most effective in improving post-resuscitation care (best practices) will inform on the design of a quality improvement intervention geared towards improving post -resuscitation care at all hospitals. This will be the subject of a future R01 by the applicant.

Public Health Relevance

Sudden death due to the heart stopping (i.e., cardiac arrest) occurs commonly among hospitalized patients in the United States. Even after successful revival with CPR, many cardiac arrest patients eventually die during the hospital stay. A patient's chance of surviving a cardiac arrest depends on the hospital in which they receive care. In other words, some hospitals are better than others in saving lives. This research project will identify hospitals that offer the best chance of survival to a cardiac arrest patient who has been successfully revived with CPR, and understand how these hospitals achieve their superior results. This knowledge will help us learn from the example of the 'best hospitals' and provide guidance on how to improve care so that all patients at all hospitals can be benefited.
