Multicenter Study Comparative Study Observational Study
Advanced vs. Basic Life Support in the Treatment of Out-of-Hospital Cardiopulmonary Arrest in the Resuscitation Outcomes Consortium.
Prior observational studies suggest no additional benefit from advanced life support (ALS) when compared with providing basic life support (BLS) for patients with out-of-hospital cardiac arrest (OHCA). We compared the association of ALS care with OHCA outcomes using prospective clinical data from the Resuscitation Outcomes Consortium (ROC). ⋯ ALS care was associated with survival to hospital discharge when provided initially or within six minutes of BLS arrival. ALS care, with or without initial BLS care, was associated with increased ROSC, however it was not associated with functional outcome.

Randomized Controlled Trial Multicenter Study
Oxygen titration after resuscitation from out-of-hospital cardiac arrest: A multi-centre, randomised controlled pilot study (the EXACT pilot trial).
Recent studies suggest the administration of 100% oxygen to hyperoxic levels following return-of-spontaneous-circulation (ROSC) post-cardiac arrest may be harmful. However, the feasibility and safety of oxygen titration in the prehospital setting is unknown. We conducted a multi-centre, phase-2 study testing whether prehospital titration of oxygen results in an equivalent number of patients arriving at hospital with oxygen saturations SpO2 ≥ 94%. ⋯ Oxygen titration post-ROSC is feasible in the prehospital environment, but incremental titration commencing at 4L/min oxygen flow may be needed to maintain an oxygen saturation >90% (NCT02499042).

Observational Study
Lower heart rate is associated with good one-year outcome in post-resuscitation patients.
Optimal hemodynamic goals in post-resuscitation patients are not clear. Previous studies have reported an association between lower heart rate and good outcome in patients receiving targeted temperature management (TTM) after out-of-hospital cardiac arrest. ⋯ Lower heart rate was independently associated with good neurologic outcome. Whether HR in post-resuscitation patients is a prognostic indicator or an important variable to be targeted by treatment, needs to be assessed in future prospective controlled clinical trials.

Multicenter Study
Demographic, social, economic and geographic factors associated with long-term outcomes in a cohort of cardiac arrest survivors.
Demographic, social, economic and geographic factors are associated with increased short-term mortality after cardiac arrest. We sought to determine if these factors are additionally associated with long-term outcome differences using a detailed clinical database linked to state-wide administrative data. ⋯ There are persistent long-term outcome differences in cardiac arrest survival based on sex, income, and geographic access acute care.

Randomized Controlled Trial
The effect of different retraining intervals on the skill performance of cardiopulmonary resuscitation in laypeople-A three-armed randomized control study.
Our study aimed to compare cardiopulmonary resuscitation (CPR) performance among laypeople with different retraining intervals. ⋯ Although young laypeople with a 3-month retraining interval had the highest pass rate when performing conventional CPR, a 6-month retraining interval may be considered for training compression-only CPR and AED when balancing outcomes and resources.
