Objective-To describe the development, design and consequent scientific implications of the Resuscitation Outcomes Consortium (ROC) population-based registry; ROC Epistry-Cardiac Arrest. Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final citable form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.Nonauthor contributions outlined in Online Appendix 1 Methods-The ROC Epistry-Cardiac Arrest is designed as a prospective population-based registry of all Emergency Medical Services (EMS)-attended 9-1-1 calls for patients with out-ofhospital cardiac arrest occurring in the geographical area described by the eight US and three Canadian regions. The data set was derived by an North American interdisciplinary steering committee. Enrolled cases include individuals of all ages who experience cardiac arrest outside the hospital, with evaluation by organized EMS personnel and: a) attempts at external defibrillation (by lay responders or emergency personnel), or chest compressions by organized EMS personnel; OR b) were pulseless but did not receive attempts to defibrillate or CPR by EMS personnel. Selected data items are categorized as mandatory or optional and undergo revisions approximately every 12 months. Where possible all definitions are referenced to existing literature. Where a common definition did not exist one was developed. Optional items include standardized CPR process data elements. It is anticipated the ROC Epistry-Cardiac Arrest will enroll between approximately 9000 and 13,500 treated all rhythm arrests and 4000 and 5000 ventricular fibrillation arrests annually and approximately 8000 EMS-attended but untreated arrests. Conflict of interest: None NIH Public AccessConclusion-We describe the rationale, development, design and future implications of the ROC Epistry-Cardiac Arrest. This paper will serve as the reference for subsequent ROC manuscripts and for the common data elements captured in both ROC Epistry-Cardiac Arrest and the ROC trials.

“…4,5 One way that community response to OHCA differs is in the number of emergency medical services (EMS) personnel dispatched to provide on-scene treatment. 6 This generally depends on EMS organizational structure. Accordingly, we sought to examine patterns of association between number of EMS personnel on-scene and survival to hospital discharge in adults with EMS-treated.…”

Volume versus outcome: More emergency medical services personnel on-scene and increased survival after out-of-hospital cardiac arrest

a b s t r a c tBackground and aim: : The large regional variation in survival after treatment of out-of-hospital cardiac arrest (OHCA) is incompletely explained. Communities respond to OHCA with differing number of emergency medical services (EMS) personnel who respond to the scene. The effect of different numbers of EMS personnel on-scene upon outcomes is unclear. We sought to evaluate the association between number of EMS personnel on-scene and survival after OHCA. Methods: We performed a retrospective review of prospectively collected data on 16,122 EMS-treated OHCA events from December 1, 2005 to May 31, 2007 from a combined population over 21 million people residing in an area of over 33,000 square miles in Canada and the United States. Number of EMS personnel on-scene was defined as the number of EMS personnel who responded to the scene of OHCA within 15 min after 9-1-1 call receipt and prior to patient death or transport away from the scene. Associations with survival to hospital discharge were assessed by using generalized estimating equations to construct multivariable logistic regression models. Results: Compared to a reference number of EMS personnel on-scene of 5 or 6, 7 or 8 EMS personnel onscene was associated with a higher rate of survival to hospital discharge, adjusted odds ratio [OR], 1.35 (95% CI: 1.05, 1.73). There was no significant difference in survival between 5 or 6 personnel on-scene versus fewer. Conclusion: More EMS personnel on-scene within 15 min of 9-1-1 call was associated with improved survival of out-of-hospital cardiac arrest. It is unlikely that this finding was mediated solely by earlier CPR or earlier defibrillation.

“…9 Paramedics from 55 emergency medical services (EMS) agencies enrolled patients with out-of-hospital cardiac arrest at 10 North American sites participating in the Resuscitation Outcomes Consortium (ROC). 10 The trial was conducted under exception from informed consent in emergency research in accordance with applicable regulatory requirements, oversight by the Food and Drug Administration and Health Canada, approval by institutional review boards in participating communities, and monitoring by an independent data and safety monitoring board appointed by the National Heart, Lung, and Blood Institute (NHLBI).…”

“…The initial dose of a trial drug, approximating current clinical practice, consisted of two syringes (one syringe if the estimated body weight was <100 lb [45.4 kg]) that were administered by rapid bolus. 10,15,16 If ventricular fibrillation or pulseless ventricular tachycardia persisted after the initial dose of the trial drug, standard resuscitation measures, and additional shocks, a supplemental dose (one syringe) of the same drug was administered. Thereafter, standard interventions for advanced life support ensued according to local practice, excluding open-label lidocaine or amiodarone before hospitalization.…”
