Predictors of neurologic outcome in patients resuscitated from out-of-hospital cardiac arrest using classification and regression tree analysis.

The estimated survival rate of 8% to 10% after out-of-hospital cardiac arrest (OHCA) remains dismal. Few studies have addressed predictors of functional neurologic outcome after successful resuscitation. The objective of the study was to identify variables associated with favorable neurologic outcomes, defined by a Glasgow Coma Scale of 14 or 15, after OHCA.

Out-of-hospital cardiac arrest: early in-hospital hypotension versus out-of-hospital factors in predicting in-hospital mortality among those surviving to hospital admission.

Objective: The purpose of this study was to determine the prevalence of in-hospital hypotension in patients surviving to admission after resuscitation from out-of-hospital cardiac arrest and compare it to that of traditional Utstein factors in predicting in-hospital mortality.

Methods: Single-center retrospective cohort of adult patients surviving to hospital admission after resuscitation from out-of-hospital sudden death between January 1, 2006 and October 31, 2009. Study variables included Utstein template data: age, sex, initial rhythm, witnessed or nonwitnessed arrest, presence or absence of bystander CPR, location of arrest, response time (time of 9-1-1 dispatch to first vehicle arrival), and hypotension (systolic pressure<90 or mean arterial pressure<60) within 24h of ROSC.

Advanced rescuer- versus citizen-witnessed cardiac arrest: Is there a difference in outcome?

Background: Substantial financial and human resources are invested in training and maintaining advanced life support (ALS) skills of paramedics who are deployed to the field in response to out-of-hospital cardiac arrest. It would be expected that patients who experience cardiac arrest in the presence of a trained health care practitioner, such as a paramedic, have better outcomes.

Objective: To compare the rates of return of spontaneous circulation (ROSC), survival to hospital admission (SHA), and survival to hospital discharge (SHD) between paramedic-witnessed out-of-hospital cardiac arrest vs.
