Event Adjudication Changes Key Results in Open-Label Trials: The AFFIRM Experience Author Block: Elaine M. Nasco, April Slee, Kent Koprowicz, Robert G. Hart, Axio Research, LLC, Seattle, WA Abstract: Background: The value of central event adjudication of endpoints in multi-center randomized trials has recently been questioned. Methods: The NIH-sponsored Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) trial randomized 4,060 atrial fibrillation patients to antiarrhythmic drugs (rhythm control) vs. rate-controlling drugs, given open-label, at 213 clinical sites. While the primary outcome was mortality, a key secondary endpoint was ischemic stroke (IS), centrally adjudicated by those reviewing source documents from which …

Introduction: To improve survival from out of hospital cardiac arrest (OHCA), the American Heart Association released guidelines in 2005. We examined the effect of these guidelines on survival in the Resuscitation Outcomes Consortium (ROC) Epistry – Cardiac Arrest. We hypothesized that survival would increase after guideline implementation. Methods: 174 EMS agencies from 8 of the 10 ROC sites were surveyed to determine 2005 AHA guideline implementation, or crossover, date. Two sites with 2005 compatible treatment algorithms prior to guideline release were not included. Patients with OHCA secondary to a non cardiac cause, EMS witnessed events, patients <18 years>old, and patients with …

Objectives: To describe and characterize a group of private insurance members taking multiple medications over a one-year period. Methods: Persons were selected for this polypharmacy analysis if they had at least five unique maintenance prescriptions in their pharmacy claims records for the period of January-March 2005, based on a customized list of chronic medications. The full set of pharmacy and medical claims for these members were evaluated for a twelve month period, October 2004 to September 2005. Standard descriptive statistics were calculated to characterize the population. Logistic regression models were used to assess the association of pharmacy claims and “safety …

Introduction: EMS protocols outlining when to attempt and terminate resuscitation for non-traumatic out-of- hospital cardiac arrest (OHCA) vary substantially across North America. The ROC Epistry is a prospective population based cohort study with uniform Utstein-style data definitions from 11 sites in North America. The purpose of this study was to compare site variation in EMS treatment and transport percentages within the ROC Epistry. We also examined the differences in overall survival in relation to the presence of ROSC prior to transport. Methods: Analysis of ROC Epistry data from 7 sites for all patients > 20 years of age with OHCA between …
