Original contributionThe use of the soterion rapid triage system in children presenting to the Emergency Department
Introduction
It is estimated that there are over 31 million pediatric visits to Emergency Departments (EDs) each year (1). Inadequately developed communication skills, the subtlety of presenting signs and symptoms, and their unique physiology make the initial assessment of children more difficult, and place the seriously ill child at higher risk of being overlooked.
Triage is the first and most critical step toward the early identification of the sick child and the timely delivery of emergency health care. Without well-defined guidelines, triage is dependent upon the skill, education and experience of the individual performing triage. Many countries have adopted national five-level triage systems due to the recognized need for a more uniform triage tool (2, 3, 4). However, there are few five-level triage systems that have been developed that address the specific needs of the pediatric patient and no studies in this country that have evaluated the effectiveness of five-level triage systems in children (5, 6).
The Soterion Rapid Triage System (SRTS) is a new, computerized five-level triage system that contains both an adult and pediatric clinical decision-making process. We have previously reported on our initial experience using the system in a mixed general patient population (7). The unique aspects surrounding the care of children and the recent emphasis on five-level triage systems prompted the further study of the SRTS in this subgroup of patients. Therefore, this study was undertaken to evaluate the system’s reliability and validity for stratifying acuity levels in children under the age of 13 years.

Methods
The SRTS is a five-level triage acuity scale with the definition of each level based on the Canadian Triage and Acuity Scale (CTAS) (3). The development of the software application has been previously described (7). The overall logic of the system is comprised of three main components: standardized observations made of the patient, the computerized analysis of vital signs, and chief complaint-based algorithms with scripted interview questions directed to the child or the child’s caretaker. The
Characteristics of the Study Subjects
During the time period between April 12, 2003 and December 12, 2003, there were a total of 38,763 ED patient visits. Of those, 7077 (18%) were children under the age of 13 years who were triaged by SRTS. The characteristics of the study subjects triaged by the SRTS are shown in Table 4. There was a significant difference in mean age throughout all triage levels, such that acuity increased as age decreased (p < 0.0001). The mean age was 5 years ± 3.9. The five most common chief complaints were:
Five-Level Triage Systems
Since the mid 1990s, Australia, Canada and England have each adopted national five-level triage systems due to the recognized need for a more uniform triage tool and the demonstration of greater inter-rater reliability with a five-level system as compared with previous three- and four-level systems (10, 11, 12, 13, 14, 15). Recently, the need for a uniform triage tool has been underscored by the American College of Emergency Physicians and the Emergency Nurses Association’s recent approval of
Limitations
This study was performed in an ED with a mixed adult and pediatric population. It is unknown whether similar results would be experienced in a high-acuity pediatric ED. One could contend, however, that the mixed patient population in this study is more representative of EDs in this country, with pediatric EDs comprising less than 10% of the total EDs in this country (29).
Also, there must be continued refinement of the clinical content of the algorithms as more outcome-related data become
Conclusions
This report represents the first study in this country on the use of a five-level triage system in children. We have demonstrated that the Soterion Rapid Triage System possesses high inter-rater reliability and validity when used to triage children younger than 13 years of age. This system has the characteristics of an ideal triage system, being highly reliable and strongly predictive of clinical outcome and resource utilization.
