BACKGROUND In a departure from the previous strategy of immediate defibrillation, the 2005 resuscitation guidelines from the American Heart Association-International Liaison Committee on Resuscitation suggested that emergency medical service (EMS) personnel could provide 2 minutes of cardiopulmonary resuscitation (CPR) before the first analysis of cardiac(More)
OBJECTIVE Cardiopulmonary resuscitation (CPR) guidelines recommend the administration of chest compressions (CC) at a standardized rate and depth without guidance from patient physiologic output. The relationship between CC performance and actual CPR-generated blood flow is poorly understood, limiting the ability to define "optimal" CPR delivery. End-tidal(More)
BACKGROUND Non-shockable arrest rhythms (pulseless electrical activity and asystole) represent an increasing proportion of reported cases of out-of-hospital cardiac arrest (OHCA). The prognostic significance of conversion from non-shockable to shockable rhythms during the course of resuscitation remains unclear. OBJECTIVE To evaluate whether(More)
BACKGROUND Withdrawing life-sustaining therapy because of perceived poor neurological prognosis (WLST-N) is a common cause of hospital death after out-of-hospital cardiac arrest (OHCA). Although current guidelines recommend against WLST-N before 72h (WLST-N<72), this practice is common and may increase mortality. We sought to quantify these effects. (More)
BACKGROUND Survival varies among those resuscitated from out-of-hospital cardiac arrest (OHCA). Evidence-based performance measures have been used to describe hospital quality of care in conditions such as acute coronary syndrome and major trauma. It remains unclear if adherence to performance measures is associated with better outcome in patients(More)
OBJECTIVES To identify variation in patient, event, and scene characteristics of out-of-hospital cardiac arrest (OOHCA) patients assessed by emergency medical services (EMS), and to investigate variation in transport practices in relation to documented prehospital return of spontaneous circulation (ROSC) within eight regional clinical centers participating(More)
OBJECTIVES To examine the relationship between Physician Orders for Life-Sustaining Treatment (POLST) for Scope of Treatment and setting of care at time of death. DESIGN Cross-sectional. SETTING Oregon in 2010 and 2011. PARTICIPANTS People who died of natural causes. MEASUREMENTS Oregon death records containing cause and location of death were(More)

BACKGROUND Physician Orders for Life-Sustaining Treatment (POLST) has become a common means of documenting patient treatment preferences. In addition to orders either for Attempt Resuscitation or Do Not Attempt Resuscitation, for patients not in cardiopulmonary arrest, POLST provides three levels of treatment: Full Treatment, Limited Interventions, and(More)
STUDY OBJECTIVE Resuscitation measures should be guided by previous patient choices about end-of-life care, when they exist; however, documentation of these choices can be unclear or difficult to access. We evaluate the concordance of a statewide registry of actionable resuscitation orders unique to Oregon with out-of-hospital and emergency department (ED)(More)
