Observational Study
What is the 30-day rate of adverse cardiac events in chest pain patients with ED troponin I assays≤99th centile using a contemporary sensitive assay? An exploratory analysis.
For nonhigh-risk patients who 'rule out' for acute coronary syndrome, Australasian guidelines recommend further testing to identify coronary artery disease. Testing is usually performed as an outpatient procedure. This recommendation has not changed with the advent of sensitive biomarker assays. We aimed to determine the 30-day rate of adverse cardiac events in emergency department (ED) chest pain patients without known coronary artery disease who had ED troponin I (TnI) assays≤99th centile using a contemporary troponin assay, stratified by the Heart Foundation (HF; Australia) risk group. ⋯ Among ED patients presenting with suspected acute coronary syndrome, adverse cardiac events at 30 days are rare in nonhigh-risk patients with contemporary TnI assays<99th centile.

Randomized Controlled Trial
Teaching basic life support: a prospective randomized study on low-cost training strategies in secondary schools.
Cardiopulmonary resuscitation (CPR) training at school is recommended. Limited school resources prevent implementation. The learning efficacy of low-cost training strategies is unknown. ⋯ Training efficacy with low-cost equipment was not different from training with a manikin. The outcome for all training strategies was suboptimal. The basics of CPR can be taught with alternative equipment if manikins are not available.

The aim of this study was to identify a reliable tool for the early prognostic stratification of septic patients admitted to the emergency department-high dependency unit (ED-HDU), a clinical setting providing a subintensive level of care; we also estimated the cost saving associated with HDU stay compared with ICU stay. ⋯ SOFA score is a feasible and accurate tool for an early risk stratification of septic patients admitted to the ED-HDU.

Critical care paramedics (CCPs) have been introduced by individual ambulance trusts in England, but there is a lack of national coordination of training and practice. We conducted an online survey of NHS ambulance services to provide an overview of the current utilization and role of CCPs in England. The survey found significant variations in training, competencies and the working patterns of the ∼90 CCPs working in five ambulance services. ⋯ The CCP model established in five ambulance services in England is unique within Europe. With increasing numbers of CCPs, concerns about lack of supportive scientific evidence and clinical need should be addressed. Optimal delivery of prehospital critical care in England remains controversial.

Blood gas analysers provide electrolyte and metabolic data. In the author's institution, these values were not used clinically because of the risk of inaccuracy. To discover whether this approach was warranted, we compared values from our Radiometer point-of-care (POC) analyser and the laboratory. ⋯ Thus, sodium and potassium showed negative bias on the Radiometer compared with the laboratory. Creatinine and haemoglobin agreed well. We advocate the clinical use of POC values when taken in clinical context.
