Multicenter StudyHospital rapid response team and patients with life-limiting illness: a multicentre retrospective cohort study.
Approximately one-third of rapid response team consultations involve issues of end-of-life care. We postulate a greater occurrence in patients with a life-limiting illness, in whom the opportunity for advance care planning and palliative care involvement should be offered. ⋯ Patients with a life-limiting illness had worse outcomes post-rapid response team consultation. Our findings suggest that a routine clarification of goals of care for this cohort, within 3 days of hospital admission, may be advantageous. These discussions may provide clarity of purpose to treating teams, reduce the burden of unnecessary interventions and promote patient-centred care agreed upon in advance of any deterioration.

Multicenter Study
Shorter time to target temperature is associated with poor neurologic outcome in post-arrest patients treated with targeted temperature management.
Time to achieve target temperature varies substantially for patients who undergo targeted temperature management (TTM) after cardiac arrest. The association between arrival at target temperature and neurologic outcome is poorly understood. We hypothesized that shorter time from initiation of cooling to target temperature ("induction") will be associated with worse neurologic outcome, reflecting more profound underlying brain injury and impaired thermoregulatory control. ⋯ In this multicenter cohort of post-arrest TTM patients, shorter induction time was associated with poor neurologic outcome.

Multicenter Study Observational Study
Correlation between initial serum levels of lactate after return of spontaneous circulation and survival and neurological outcomes in patients who undergo therapeutic hypothermia after cardiac arrest.
We analysed the relationship between serum levels of lactate within 1h of return of spontaneous circulation (ROSC) and survival and neurological outcomes in patients who underwent therapeutic hypothermia (TH). ⋯ High levels of lactate in serum measured within 1h of ROSC are associated with hospital mortality and high CPC scores in cardiac arrest patients treated with TH.

Multicenter Study Observational Study
Amplitude spectrum area to guide defibrillation: a validation on 1617 patients with ventricular fibrillation.
This study sought to validate the ability of amplitude spectrum area (AMSA) to predict defibrillation success and long-term survival in a large population of out-of-hospital cardiac arrests. ⋯ In this large derivation-validation study, AMSA was validated as an accurate predictor of defibrillation success. AMSA also appeared as a predictor of long-term survival.

Multicenter StudyImplementation of a dispatch-instruction protocol for cardiopulmonary resuscitation according to various abnormal breathing patterns: a population-based study.
We modified the dispatch protocol for cardiopulmonary resuscitation (CPR) using results of a retrospective analysis that identified descriptions by laypersons of possible patterns of agonal respiration. The purpose of this study was to assess the effectiveness of this modified protocol by comparing the frequency of dispatch instructions for CPR and bystander CPR before and after protocol implementation. We also identified descriptions of abnormal breathing patterns among 'Not in cardiac arrest (CA)' unresponsive cases. ⋯ This modified protocol based on abnormal breathing described by laypersons significantly increased CPR instructions. Considering high sensitivity and low specificity for abnormal breathing to identify CA and the low risk of chest compression for 'Not in CA' cases, our study suggested that dispatchers can provide CPR instruction assertively and safely for those unresponsive individuals with various abnormal breathing patterns.
