Bystander CPR rates are lowest at home, where 85% of out-of-hospital cardiac arrests occur. We sought to identify barriers and facilitators to CPR training and performing CPR among older individuals most likely to witness cardiac arrest. ⋯ Attitudinal beliefs were most predictive of respondents' intention to complete CPR training or perform CPR on a real victim. Behavioral change techniques targeting these specific beliefs are most likely to make an impact.

Few studies have described the value of the precordial thump (PT) as first-line treatment of monitored out-of-hospital cardiac arrest (OHCA) from ventricular fibrillation and pulseless ventricular tachycardia (VF/VT). ⋯ The PT used as first-line treatment of monitored VF/VT rarely results in ROSC, and is more often associated with rhythm deterioration.

Post-cardiac arrest fever has been associated with adverse outcome before implementation of therapeutic hypothermia (TH), however the prognostic implications of post-hypothermia fever (PHF) in the era of modern post-resuscitation care including TH has not been thoroughly investigated. The aim of the study was to assess the prognostic implication of PHF in a large consecutive cohort of comatose survivors after out-of-hospital cardiac arrest (OHCA) treated with TH. ⋯ Post-hypothermia fever ≥38.5°C is associated with increased 30-days mortality, even after controlling for potential confounding factors. Avoidance of PHF as a therapeutic target should be evaluated in prospective randomized trials.

The possibility of successful defibrillation decreases with an increased duration of ventricular fibrillation (VF). Futile electrical shocks are inversely correlated with myocardial contractile function and long-term survival. Previous studies have demonstrated that various ECG waveform analyses predict the success of defibrillation. This study investigated whether the absolute amplitude of pre-shock VF waveform is likely to predict the success of defibrillation. ⋯ Signal integral predicted successful electrical shocks on patients with ventricular fibrillation and have potential to optimize the timing of defibrillation and reduce the number of electrical shocks.

Rapid response teams (RRTs) are frequently employed to respond to deteriorating inpatients. Proactive rounding (PR) consists of the RRT nurse rounding through the inpatient wards identifying high risk patients and intervening preemptively. At our institution, PR began in July of 2007. Our objective was to determine the effect of PR by the RRT at our institution on non-ICU cardiac arrests, code deaths, RRT interventions, and transfers to a higher level of care. Also, to report ICU transfer survival and survival to discharge rates after the start of PR. ⋯ The institution of proactive rounding at a tertiary care, academic, level 1 trauma center results in reduced floor codes and code deaths as well as increased RRT interventions and transfers to a higher level of care.
