Multicenter Study
Signs of critical conditions and emergency responses (SOCCER): a model for predicting adverse events in the inpatient setting.
Emergency response systems (ERS) are based on a set of triggers used to identify patients "at risk". This study aimed to establish the association between recordings of disturbed physiological variables and adverse events. ⋯ Both ES and LS were associated with adverse events. This study confirms the validity of current MET call criteria but points to the need to expand them. It provides a possible explanation for the failure to demonstrate efficacy of a MET in some trials because current call criteria maybe too late in the progress of the patient's critical condition. It allows the modelling of ERS and education programmes focused on signs of critical conditions. It potentially brings together ICU outreach and ward based responses. Broader use of clinical signs, monitoring such as pulse oximetry and objective data such as blood gas results may assist early intervention and help prevent loss of life.

Randomized Controlled Trial Multicenter Study
Survival from prehospital cardiac arrest is critically dependent upon response time.
This study correlated the delay in initiation of bystander cardiopulmonary resuscitation (ByCPR), basic (BLS) or advanced cardiac (ACLS) life support, and transport time (TT) to survival from prehospital cardiac arrest. This was a secondary endpoint in a study primarily evaluating the effect of bicarbonate on survival. ⋯ Delay to the initiation of BLS and ACLS intervention influenced outcome from prehospital cardiac arrest negatively. There were no survivors after prolonged delay in initiation of ACLS of 30 min or greater or total resuscitation and transport time of 90 min. This result was not influenced by giving bicarbonate, the primary study intervention, except at longer arrest times.
