The Soterion Rapid Triage System is a new, computerized, five-level triage acuity system. The purpose of this study was to evaluate the system's inter-rater reliability and validity for stratifying patient acuity. The study was comprised of two components. A prospective evaluation of inter-rater reliability was conducted by the blinded, paired simultaneous triage of 423 patients. A retrospective evaluation of validity consisted of the analysis of 33,850 patients triaged with the system over an 8-month period. The system's validity was measured by in-hospital admission rate, Emergency Department (ED) length-of-stay, hospital charges and Current Procedural Terminology (CPT) Codes 99281-99285. Evaluation of inter-rater reliability demonstrated a weighted kappa of 0.87 (95% confidence interval 0.84, 0.91). The in-hospital admission rates for patients triaged as Level 1 Immediate-Level 5 Non-Urgent were 43%, 30%, 13%, 3% and 1%, respectively (p < 0.0001). Similarly, there were significant differences in the means for all hospital charges, ED lengths-of-stay, and CPT Codes. In conclusion, the Soterion Rapid Triage System possesses high inter-rater reliability and validity. The system's reliability and validity, and the availability of the system's electronically archived data are characteristics beneficial to the development of a national standardized five-level triage acuity system.

Hypothermia, occurring when the core body temperature falls below 35 degrees C, gives rise to life threatening physiological changes, and may present in the Accident and Emergency (A & E) department with varying aetiology and implications for nursing management. Rewarming the hypothermic patient is a priority of nursing care, and several different ways of achieving this are practised. This review of relevant literature aims to evaluate current methods of rewarming hypothermic patients commonly employed, their associated difficulties, and considers their potential implementation in the A & E setting.
