Regional Variation in Out-of-Hospital Cardiac Arrest Incidence and Outcome
Graham Nichol,Elizabeth Thomas,Clifton W. Callaway,Jerris R. Hedges,Judy Powell,Tom P. Aufderheide,Thomas D. Rea,Robert A. Lowe,Todd M. Brown,John Dreyer,Daniel Davis,Ahamed H. Idris,Ian G. Stiell +12 more
TL;DR: In this study involving 10 geographic regions in North America, there were significant and important regional differences in out-of-hospital cardiac arrest incidence and outcome.
Journal ArticleDOI
Chest Compression Fraction Determines Survival in Patients With Out-of-Hospital Ventricular Fibrillation
Jim Christenson,Douglas L. Andrusiek,Siobhan Everson-Stewart,Peter J. Kudenchuk,David Hostler,Judy Powell,Clifton W. Callaway,Dan Bishop,Christian Vaillancourt,Daniel P. Davis,Tom P. Aufderheide,Ahamed H. Idris,John A Stouffer,Ian G. Stiell,Robert A. Berg +14 more
TL;DR: An increased chest compression fraction is independently predictive of better survival in patients who experience a prehospital ventricular fibrillation/tachycardia cardiac arrest.
Journal ArticleDOI
Quality of Life in the Antiarrhythmics Versus Implantable Defibrillators Trial Impact of Therapy and Influence of Adverse Symptoms and Defibrillator Shocks
Eleanor Schron,Derek V. Exner,Qing Yao,Louise S Jenkins,Jonathan S Steinberg,James R Cook,Steven P Kutalek,Peter L. Friedman,Rosemary S. Bubien,Richard L Page,Judy Powell +10 more
TL;DR: ICD and AAD therapy are associated with similar alterations in self-perceived QoL over 1-year follow-up, and sporadic shocks were associated with reducedQoL in ICD recipients.
Journal ArticleDOI
Survival After Application of Automatic External Defibrillators Before Arrival of the Emergency Medical System: Evaluation in the Resuscitation Outcomes Consortium Population of 21 Million
Myron L. Weisfeldt,Colleen M. Sitlani,Joseph P. Ornato,Thomas D. Rea,Tom P. Aufderheide,Daniel Davis,Jonathan Dreyer,Erik P. Hess,Jonathan Jui,Justin Maloney,George Sopko,Judy Powell,Graham Nichol,Laurie J. Morrison +13 more
TL;DR: Application of an AED in communities is associated with nearly a doubling of survival after out-of-hospital cardiac arrest, and these results reinforce the importance of strategically expanding community-based AED programs.
Journal ArticleDOI
What is the Role of Chest Compression Depth during Out-of-Hospital Cardiac Arrest Resuscitation?
Ian G. Stiell,Siobhan P. Brown,Jim Christenson,Sheldon Cheskes,Graham Nichol,Judy Powell,Blair L. Bigham,Laurie J. Morrison,Jonathan Larsen,Erik P. Hess,Christian Vaillancourt,Daniel P. Davis,Clifton W. Callaway +12 more
TL;DR: A strong association between survival outcomes and increased compression depth is found but no clear evidence to support or refute the 2010 recommendations of >50 mm is found.
