Validity of the Manchester Triage System in paediatric emergency care

Emergency pediatric patients and use of the pediatric assessment triangle tool (PAT): a scoping review

BACKGROUND

We conducted a scoping review of the evidence for the use of the Pediatric Assessment Triangle (PAT) tool in emergency pediatric patients, in hospital and prehospital settings. We focused on the psychometric properties of the PAT, the reported impact, the setting and circumstances for tool implementation in clinical practice, and the evidence on teaching the PAT.

METHODS

We followed the Joanna Briggs Institute methodology for scoping reviews and registered the review protocol. We searched MEDLINE, PubMed Central, the Cochrane Library, Epistemonikos, Scopus, CINAHL, Grey literature report, Lens.org, and the web pages of selected emergency pediatrics organizations in August 2022. Two reviewers independently screened and extracted data from eligible articles.

RESULTS

Fifty-five publications were included. The evidence suggests that the PAT is a valid tool for prioritizing emergency pediatric patients, guiding the selection of interventions to be undertaken, and determining the level of care needed for the patient in both hospital and prehospital settings. The PAT is reported to be fast, practical, and useful potentially impacting overcrowded and understaff emergency services. Results highlighted the importance of instruction prior using the tool. The PAT is included in several curricula and textbooks about emergency pediatric care.

CONCLUSIONS

This scoping review suggests there is a growing volume of evidence on the use of the PAT to assess pediatric emergency patients, some of which might be amenable to a systematic review. Our review identified research gaps that may guide the planning of future research projects. Further research is warranted on the psychometric properties of the PAT to provide evidence on the tool's quality and usefulness. The simplicity and accuracy of the tool should be considered in addressing the current healthcare shortages and overcrowding in emergency services.

Epidemiological trends of febrile infants presenting to the Paediatric Emergency department, in a tertiary care hospital, Karachi, Pakistan: a retrospective review

BACKGROUND

Understanding the epidemiological patterns of febrile infants can offer valuable insights for optimising management strategies and developing quality improvement initiatives, aiming to improve healthcare delivery in high-volume, low-resource emergency departments (EDs).

OBJECTIVES

To characterise the epidemiology of febrile infants presenting to the paediatric ED of a tertiary care hospital.

METHODS

A retrospective chart review of medical records was performed for febrile infants ≤1 year old, at paediatric ED, Indus Hospital and Health Network (IHHN), Karachi, Pakistan (1 January 2020-31 December 2020).

RESULTS

There were a total of 2311 patients in the study, with a male-to-female ratio of 1.4:1. The mean age of presentation was 4.9±2.7 months. Cough (n=1002, 43.2%) was the most frequent presenting symptom. The most common provisional ED diagnosis in ≤1 month of age was sepsis (n=98, 51%), bronchopneumonia (n=138, 28.6%) in 1.1-3 and 3.1-6 months (n=176, 36.45%); and upper respiratory tract illness (n=206, 47.4%) in 6.1-12 months of age. Age was significantly associated with provisional ED diagnosis and outcomes (p<0.001). Of 175 ED admissions (n=47, 26.8%), patients were discharged with a hospital diagnosis of bronchopneumonia and (n=27, 15.4) of sepsis. The infant mortality rate was 3/1000 live births.

CONCLUSIONS

This study is the first of its kind to explore the epidemiology of febrile infants in Pakistan, highlighting the burden and severity of respiratory illnesses and sepsis. It underscores the challenges of resource-limited settings, failing to meet the need for admission of febrile infants presenting to ED, IHHN. Moreover, it has highlighted the necessity to optimise the existing triage systems to effectively allocate resources and manage high patient volumes in low-resource EDs.

A low proportion of undertriage validates the new West coast system for triage-Paediatric

AIM

There is a lack of studies on paediatric triage systems. This study aimed to evaluate patient safety of the Gothenburg-developed paediatric triage system West Coast System for Triage-Paediatric (WEST-P).

METHOD

This study was performed at the paediatric emergency department in Gothenburg, Sweden, October 2020 to April 2021. Included patients were double-triaged with the WEST-P, and the established Rapid Emergency Triage and Treatment System-Paediatrics (RETTS-p). We compared the level of urgency between both systems to identify potentially undertriaged patients. Also, we assessed the patient safety according to clinical assessment at presentation, and pre-defined criteria.

RESULTS

This study included 2290 (23%) of triaged patients (44% girls, median age: 5.0 years) during the study period. A higher number of patients triaged to low urgency in WEST-P compared to RETTS-p (p < 0.0001) was observed, and 497 cases with low WEST-P and high RETTS-p urgencies identified. Of these, 29 had a clinical assessment indicating high urgency. After patient safety assessment, seven (0.4%) were determined undertriaged by the new triage system WEST-P.

CONCLUSION

Our findings demonstrate a low risk of undertriage in the new WEST-P. Thus, the WEST-P has a high degree of patient safety when used in a paediatric emergency department.

Five Level Triage vs. Four Level Triage in a Quaternary Emergency Department: National Analysis on Waiting Time, Validity, and Crowding-The CREONTE (Crowding and RE-Organization National TriagE) Study Group

Background and Objectives: Triage systems help provide the right care at the right time for patients presenting to emergency departments (EDs). Triage systems are generally used to subdivide patients into three to five categories according to the system used, and their performance must be carefully monitored to ensure the best care for patients. Materials and Methods: We examined ED accesses in the context of 4-level (4LT) and 5-level triage systems (5LT), implemented from 1 January 2014 to 31 December 2020. This study assessed the effects of a 5LT on wait times and under-triage (UT) and over-triage (OT). We also examined how 5LT and 4LT systems reflected actual patient acuity by correlating triage codes with severity codes at discharge. Other outcomes included the impact of crowding indices and 5LT system function during the COVID-19 pandemic in the study populations. Results: We evaluated 423,257 ED presentations. Visits to the ED by more fragile and seriously ill individuals increased, with a progressive increase in crowding. The length of stay (LOS), exit block, boarding, and processing times increased, reflecting a net raise in throughput and output factors, with a consequent lengthening of wait times. The decreased UT trend was observed after implementing the 5LT system. Conversely, a slight rise in OT was reported, although this did not affect the medium-high-intensity care area. Conclusions: Introducing a 5LT improved ED performance and patient care.

Validity of the Brazilian pediatric triage system CLARIPED at a secondary level of emergency care

OBJECTIVE

To evaluate the validity of the triage system CLARIPED in a pediatric population in the city of São Paulo, Brazil.

METHODS

Prospective, observational study in a secondary-level pediatric emergency service from Sep-2018 to Ago-2019. A convenience sample of all patients aged 0-18 years triaged by the computerized CLARIPED system was selected. Associations between urgency levels and patient outcomes were analyzed to assess construct validity. Sensitivity, specificity, and positive and negative predictive values (PPV and NPV) to identify the most urgent patients were estimated, as well as under-triage and over-triage rates.

RESULTS

The distribution of 24,338 visits was: RED 0.02%, ORANGE 0.9%, YELLOW 23.5%, GREEN 47.9%, and BLUE 27.7% (highest to the lowest level of urgency). The frequency of the following outcomes increased with increasing urgency: hospital admission (0.0%, 0.02%, 0.1%, 7.1% and 20%); stay in ED observation room (1.9%, 2,4%, 4.8%, 24.1%, 60%); use of ≥ 2 diagnostic/therapeutic resources (2.3%, 3.0%, 5.9%, 28.8%, 40%); ED length of stay (12, 12, 15, 99.5, 362 min). The most urgent patients (RED, ORANGE, and YELLOW) exhibited higher chances of using ≥ 2 resources (OR 2.55; 95%CI: 2.23-2.92) or of being hospitalized (OR 23.9; 95%CI: 7.17-79.62), compared to the least urgent (GREEN and BLUE). The sensitivity to identify urgency was 0.88 (95%CI: 0.70-0.98); specificity, 0.76 (95%CI: 0.75-0.76); NPV, 0.99 (95%CI: 0.99-1.00); overtriage rate, 23.0%, and undertriage, 11.5%.

CONCLUSION

This study corroborates the validity and safety of CLARIPED, demonstrating significant correlations with clinical outcomes, good sensitivity, and low undertriage rate in a secondary-level Brazilian pediatric emergency service.

Validity of the computerized version of the pediatric triage system CLARIPED for emergency care

OBJECTIVE

To evaluate the validity of the computerized version of the pediatric triage system CLARIPED.

METHODS

Prospective, observational study in a tertiary emergency department (ED) from Jan-2018 to Jan-2019. A convenience sample of patients aged 0-18 years who had computerized triage and outcome variables registered. Construct validity was assessed through the association between urgency levels and patient outcomes. Sensitivity, specificity, positive and negative predictive values (PPV and NPV), undertriage, and overtriage rates were assessed.

RESULTS

19,122 of 38,321 visits were analyzed. The urgency levels were: RED (emergency) 0.02%, ORANGE (high urgency) 3.21%, YELLOW (urgency) 35.69%, GREEN (low urgency) 58.46%, and BLUE (no urgency) 2.62%. The following outcomes increased according to the increase in the level of urgency: hospital admission (0.4%, 0.6%, 3.1%, 11.9% and 25%), stay in the ED observation room (2.8%, 4.7%, 15.9%, 40.4%, 50%), ≥ 2 diagnostic or therapeutic resources (7.8%, 16.5%, 33.7%, 60.6%, 75%), and ED length of stay in minutes (18, 24, 67, 120, 260). The odds of using ≥ 2 resources or being hospitalized were significantly greater in the most urgent patients (Red, Orange, and Yellow) compared to the least urgent (Green and Blue): OR 7.88 (95%CI: 5.35-11.6) and OR 2.85 (95%CI: 2.63-3.09), respectively. The sensitivity to identify urgency was 0.82 (95%CI: 0.77-0.85); specificity, 0.62 (95%CI: 0.61-0.6; NPV, 0.99 (95%CI: 0.99-1.00); overtriage rate, 4.28% and undertriage, 18.41%.

CONCLUSION

The computerized version of CLARIPED is a valid and safe pediatric triage system, with a significant correlation with clinical outcomes, good sensitivity, and low undertriage rate.

Reliability and Validity of a New Computer-Based Triage Decision Support Tool: ANKUTRIAGE

OBJECTIVE

Triage is a tool used to determine patients' severity of illness or injury within minutes of arrival. This study aims to assess the reliability and validity of a new computer-based triage decision support tool, ANKUTRIAGE, prospectively.

METHODS

ANKUTRIAGE, a 5-level triage tool was established considering 2 major factors, patient's vital signs and characteristics of the admission complaint. Adult patients admitted to the ED between July and October, 2019 were consecutively and independently double triaged by 2 assessors using ANKUTRIAGE system. To measure inter-rater reliability, quadratic-weighted kappa coefficients (Kw) were calculated. For the validity, associations among urgency levels, resource use, and clinical outcomes were evaluated.

RESULTS

The inter-rater reliability between users of ANKUTRIAGE was excellent with an agreement coefficient (Kw) greater than 0.8 in all compared groups. In the validity phase, hospitalization rate, intensive care unit admission and mortality rate decreased from level 1 to 5. Likewise, according to the urgency levels, resource use decreased significantly as the triage level decreased (P < 0.05).

CONCLUSIONS

ANKUTRIAGE proved to be a valid and reliable tool in the emergency department. The results showed that displaying the key discriminator for each complaint to assist decision leads to a high inter-rater agreement with good correlation between urgency levels and clinical outcomes, as well as between urgency levels and resource consumptions.

Analysis of the validity of the five-level TRIPED-GM paediatric triage system

OBJECTIVE

To determine the validity of the five-level TRIPED-GM pediatric triage system.

METHODS

Unicentric, observational, descriptive, cross-sectional study of 485 patients aged 0-16 years in the pediatric emergency department of the HGU Gregorio Marañon. Two measures of validity were used: a direct measure calculated by the sensitivity and specificity obtained based on the number of infratriages and overtriages of the priorities given by classification nurses compared with a panel of experts and another indirect measure by the length of stay, the resources consumed and the percentage of income for each priority level.

RESULTS

10 patients were incorrectly classified, 4 (0.8%) were considered infratriages and 6 (1.2%) overtriages. The results showed a sensitivity of 99.45% (95% CI 96.5-99.97%) and a specificity of 99.01% (95% CI 96.9-99.7%) for high priorities (P2 and P3) and 98.99% (95% CI 96.8-99.6%) and 98.4% (95% CI 96.84-99.74%) respectively for low priorities (P4 and P5). The quadratic weighted Kappa index was 0.96 (95% CI 0.94-0.98; p = 0.0000). Resource consumption showed moderate Spearman correlation coefficients as the priority level increased. The percentage of admissions and the need for observation increased as the priority level p = 0,000 increased, not requiring observation or admitting any patients with priority 5.

CONCLUSIONS

The TRIPED-GM pediatric triage system is valid for use in emergency departments with similar patients.

Reliability and validity of the Netherlands Triage Standard in emergency care settings: a case scenario study

BACKGROUND

The Netherlands Triage Standard (NTS) is a triage system that can be used by different types of emergency care organisations. Our objective was to determine the interrater reliability and construct validity of the NTS when applied to self-presenting patients.

METHODS

We performed a cross-sectional case scenario study consisting of two parts: (1) paediatric triage in January-February 2019 and (2) adult triage in October-November 2020. In each part, we invited nurse triagists from three general practitioner cooperatives, three ambulance dispatching centres and three hospital emergency departments in the Netherlands to participate. We used 40 case scenarios involving paediatric patients and 41 involving adult patients who could self-present to any emergency care organisation. In advance, an expert panel determined the urgency (six levels) of the case scenarios (reference standard). The main outcome for reliability was the intraclass correlation coefficient (ICC) for urgency level. The main outcomes for validity were degree of agreement with the reference standard, for urgency level, and sensitivity and specificity for high versus low urgency. We used descriptive statistics and logistic multilevel modelling with both case and triagist as random effects.

RESULTS

218 out of 240 invited triagists participated. The ICC among all triagists was 0.73 for paediatric cases and 0.88 for adult cases and was highest in general practitioner cooperatives. For paediatric cases, there was 62.3% agreement with the reference standard about urgency, 17.4% underestimation and 20.2% overestimation. The sensitivity of the NTS for identifying highly urgent paediatric cases was 85.2%; the specificity was 89.7%. For adult cases, there was 68.3% agreement, 13.7% underestimation and 18.0% overestimation. The sensitivity of triage for high urgency in adults was 94.5% and the specificity 83.3%.

CONCLUSION

NTS appears to have good reliability and construct validity for estimating the urgency of health complaints of non-referred patients presenting themselves in emergency care.

The Manchester Triage System in a Pediatric Emergency Department of an Austrian University Hospital: A Retrospective Analysis of Urgency Levels

OBJECTIVES

The Manchester Triage System (MTS) has entered widespread international use in emergency departments (EDs). This retrospective study analyzes urgency of patient visits (PV) at the ED of the Clinic for Pediatrics at the Medical University of Innsbruck.

METHODS

We collected demographic and outcome information, including PV urgency levels (UL) according to the MTS, for 3 years (2015-2018), separating PV during regular office hours (ROH; 8:00 am to 5:00 pm) from PV during afternoon and night hours (5:00 pm to 8:00 am), and PV on weekdays from PV on weekends and bank holidays (WE).

RESULTS

A total of 56,088 PV were registered with a UL. Most (68.4%) PV were classified as nonurgent. During ROH, more PV per hour (PV/h) were recorded than during afternoon and night hours (3.0 PV/h vs 1.6 PV/h), with a higher proportion of less urgent cases during ROH. On WE, the amount of PV/h was higher than on weekdays (3.6 PV/h vs 2.8 PV/h), with a higher proportion of nonurgent cases (74.6% vs 68.6%). Likelihoods of inpatient admission and hospital stay lengths increased in step with UL.

CONCLUSIONS

The MTS proved useful for delineating UL distributions. The MTS analyses may be of value in managing EDs. Prompted by the results of our study, a general practice pediatric care unit was established to support the ED during WE.

Validation of the Computerized Pediatric Triage Tool, pediaTRI, in the Pediatric Emergency Department of Lenval Children's Hospital in Nice: A Cross-Sectional Observational Study

INTRODUCTION

A reliable pediatric triage tool is essential for nurses working in pediatric emergency departments to quickly identify children requiring priority care (high-level emergencies) and those who can wait (low-level emergencies). In the absence of a gold standard in France, the objective of our study was to validate our 5-level pediatric triage tool -pediaTRI- against the reference tool: the Pediatric Early Warning Score (PEWS) System.

MATERIALS AND METHODS

We prospectively included 100,506 children who visited the Pediatric Emergency Department at Lenval Children's Hospital (Nice, France) in 2016 and 2017. The performance of pediaTRI to identify high-level emergencies (severity levels 1 and 2) was evaluated in comparison with a PEWS ≥ 4/9. Data from 2018-19 was used as an independent validation cohort.

RESULTS

pediaTRI agreed with the PEWS score for 84,896 of the patients (84.5%): 15.0% (14.8-15.2) of the patients were over-triaged and 0.5% (0.5-0.6) under-triaged compared with the PEWS score. pediaTRI had a sensitivity of 76.4% (74.6-78.2), a specificity of 84.7% (84.4-84.9), and positive and negative likelihood ratios of 5.0 (4.8-5.1) and 0.3 (0.3-0.3), respectively, for the identification of high-level emergencies. However, the positive likelihood ratios were lower for patients presenting with a medical complaint [4.1 (4.0-4.2) v 10.4 (7.9-13.7 for trauma), and for younger children [1.2 (1.1-1.2) from 0 to 28 days, and 1.9 (1.8-2.0) from 28 days to 3 months].

CONCLUSION

pediaTRI has a moderate to good validity to triage children in a Pediatric Emergency Department with a tendency to over-triage compared with the PEWS system. Its validity is lower for younger children and for children consulting for a medical complaint.

Improving the safety of the Manchester triage system for children with congenital heart disease

This study is a prospective evaluation of the validity of a Manchester triage system (MTS) modification for detecting under-triaged pediatric patients with congenital heart disease (CHD). Children with CHD visiting the emergency unit of the Department of Pediatrics and Adolescent Medicine, University Hospital Vienna in 2014 were included. The MTS modification updated the prioritization of patients with complex syndromic diseases, specific symptoms related to chronic diseases, decreased general condition (DGC), profound language impairment, unknown medical history, or special needs. A four-level outcome severity index based on diagnostic and therapeutic interventions, admission to hospital, and follow-up strategies was defined as a reference standard for the correct clinical classification of the MTS urgency level. Of the 19,264 included children, 940 had CHD. Of this group, 266 fulfilled the inclusion criteria for the modified triage method. The MTS modification was significantly more often applied in under-triaged (65.9%) than correctly or over-triaged (25%) children with CHD (p-value χ² test < 0.0001, OR 5.848, 95% CI: 3.636-9.6).

CONCLUSION

The MTS urgency level upgrade modification could reduce under-triage in children with CHD. Applying a safety strategy concept to the MTS could mitigate under-triage in such a high-risk patient group.

WHAT IS KNOWN

• The Manchester triage system is considered to be valid and reliable but tends to over-triage. • A study by Seiger et al. showed poor performance in children with chronic illnesses, especially in children with cardiovascular diseases.

WHAT IS NEW

• The MTS modification with one urgency level upgrade could decrease under-triage in children with congenital heart disease. • As reference standard a four level outcome severity index (OSI) was established to include diagnostic investigations, medical interventions, hospital admission or follow up visits in the assessment.

Decision-making for children requiring interhospital transport: assessment of a novel triage tool

OBJECTIVE

The use of specialist retrieval teams to transport critically ill children is associated with reduced risk-adjusted mortality and morbidity; however, there is a paucity of data to guide decision-making related to retrieval team activation. We aimed to assess the accuracy of a novel triage tool designed to identify critically ill children at the time of referral for interhospital transport.

DESIGN

Prospective observational study.

SETTING

Regional paediatric retrieval and transport services.

PATIENTS

Data were collected for 1815 children referred consecutively for interhospital transport from 87 hospitals in Queensland and northern New South Wales.

INTERVENTION

Implementation of the Queensland Paediatric Transport Triage Tool.

MAIN OUTCOME MEASURES

Accuracy was assessed by calculating the sensitivity, specificity and negative predictive value for predicting transport by a retrieval team, or admission to intensive care following transport.

RESULTS

A total of 574 (32%) children were transported with a retrieval team. Prediction of retrieval (95% CIs): sensitivity 96.9% (95% CI 95.1% to 98.1%), specificity 91.4% (95% CI 89.7% to 92.9%), negative predictive value 98.4% (95% CI 97.5% to 99.1%). There were 412 (23%) children admitted to intensive care following transport. Prediction of intensive care admission: sensitivity 96.8% (95% CI 94.7% to 98.3%), specificity 81.2% (95% CI 79.0% to 83.2%), negative predictive value 98.9% (95% CI 98.1% to 99.4%).

CONCLUSIONS

The triage tool predicted the need for retrieval or intensive care admission with high sensitivity and specificity. The high negative predictive value indicates that, in our setting, children categorised as acutely ill rather than critically ill are generally suitable for interhospital transport without a retrieval team.

The new emergency department "Tuscan triage System". Validation study

INTRODUCTION

A new organizational framework was recently implemented in Tuscan Emergency Departments (EDs), including specific low-priority streaming. A new ED triage system, named "Tuscan Triage System" (TTS), was devised with the purpose of applying this reorganization.

METHODS

A validation study was designed with the primary aims of assessing the content, face, and criterion validities, and the inter-rater reliability of the TTS. The secondary aim was to estimate the differences in triage level assignation between the previous "Regional Triage System" (RTS) and the TTS. Twenty-four nurses trained for the TTS were enrolled to assign TTS priority levels to 100 triage clinical case vignettes drawn up by the developers of the TTS (reference standard).

RESULTS

The Content Validity Index - Scale/Average (S-CVI/Ave) of TTS was 0.98. Concerning to face validity, the S-CVI/Ave was 1. The highest adherence of triage level assignation to the reference standard was for levels 1 and 2. The Krippendorff α value was 0.808. Undertriage and overtriage were 10.45% and 14.29%, respectively. Overall, the comparation between RTS and TTS showed a marked shift of level assignation towards TTS low priority levels.

CONCLUSIONS

The TTS seems to be safe. These results should be confirmed through studies in the real clinical settings.

The performance of the EMS triage (RETTS-p) and the agreement between the field assessment and final hospital diagnosis: a prospective observational study among children < 16 years

Background

The rapid triage and treatment system for paediatrics (RETTS-p) has been used by the emergency medical services (EMS) in the west of Sweden since 2014. The performance of the RETTS-p in the pre-hospital setting and the agreement between the EMS nurse’s field assessment and the hospital diagnosis is unknown. The aim of this study was to evaluate the performance of the RETTS-p in the EMS and the agreement between the EMS field assessment and the hospital diagnosis.

Methods

A prospective observational study was conducted among 454 patients < 16 years of age who were assessed and transported to the PED. Two instruments were used for comparison: 1) Classification of an emergent patient according to predefined criteria as compared to the RETTS-p and 2) Agreement between the EMS nurse’s field assessment and the hospital diagnosis.

Results

Among all children, 11% were identified as having vital signs associated with an increased risk of death and 7% were diagnosed in hospital with a potentially life-threatening condition. Of the children triaged with RETTS-p (85.9%), 149 of 390 children (38.2%) were triaged to RETTS-p red or orange (life-threatening, potentially life-threatening), of which 40 (26.8%) children were classified as emergent. The hospitalised children were triaged with the highest frequency to level yellow (can wait; 41.5%). In children with RETTS-p red or orange, the sensitivity for a defined emergent patient was 66.7%, with a corresponding specificity of 67.0%. The EMS field assessment was in agreement with the final hospital diagnosis in 80% of the cases.

Conclusions

The RETTS-p sensitivity in this study is considered moderate. Two thirds of the children triaged to life threatening or potentially life threatening were later identified as non-emergent. Of those, one in six was discharged from the PED without any intervention. Further, one third of the children were under triaged, the majority were found in the yellow triage level (can wait). The highest proportion of hospitalised patients was found in the yellow triage level. Our result is in agreement with previous studies using other triage instruments. A computerised decision support system might help the EMS triage to increase sensitivity and specificity.

VALIDITY AND RELIABILITY OF THE MANCHESTER SCALE USED IN THE ORTHOPEDIC EMERGENCY DEPARTMENT

Objectives:

To describe the clinical utility of the Manchester triage scale adapted for orthopedic emergency departments and to evaluate its validity in identifying patients with the need for hospital care and its reliability when reproduced by different professionals.

Methods:

Five triage flowcharts were developed based on the Manchester scale for the following orthopedic disorders: traumatic injuries, joint pain, vertebral pain, postoperative disorders, and musculoskeletal infections. A series of patients triaged by two orthopedists was analyzed to assess the concordance between the evaluators (reliability) and the validity of the Manchester scale as predictive of severity.

Results:

The reliability analysis included 231 patients, with an inter-observer agreement of 84% (Kappa = 0.77, p <0.001). The validity analysis included 138 patients. The risk category had a strong association with the need for hospital care in patients with trauma (OR = 6.57, p = 0.001) and was not significant for non-traumatic disorders (OR = 2.42; p = 0.208). The overall sensitivity and specificity were 64% and 76%, respectively.

Conclusion:

The evaluated system presented high reliability. Its validity was adequate, with good sensitivity for identifying patients requiring hospital care among those with traumatic lesions. However, the sensitivity was low for patients with non-traumatic lesions. Level of Evidence III, Retrospective Study.

2019 WACEM - Academic College of Emergency Experts Consensus Recommendations on Admission Criteria to Pediatric Intensive Care Unit from the Emergency Departments in India

There is a global variation in policies that define clear indications for pediatric intensive care unit (PICU) admissions. In resource-limited countries where PICU service availability is limited, the admission criteria to PICU are urgently needed to optimize the utilization of available intensive care services and to maximize patient benefit. The objective of these consensus recommendations on PICU admission criteria is to provide a framework and reference for future policy development by professional societies and governments.

VALIDADE E CONFIABILIDADE DE UM NOVO SISTEMA DE CLASSIFICAÇÃO DE RISCO PARA EMERGÊNCIAS PEDIÁTRICAS: CLARIPED

Objective:

To assess the validity and reliability of a triage system for pediatric emergency care (CLARIPED) developed in Brazil.

Methods:

Validity phase: prospective observational study with children aged 0 to 15 years who consecutively visited the pediatric emergency department (ED) of a tertiary hospital from July 2 to 18, 2013. We evaluated the association of urgency levels with clinical outcomes (resource utilization, ED admission rate, hospitalization rate, and ED length of stay); and compared the CLARIPED performance to a reference standard. Inter-rater reliability phase: a convenience sample of patients who visited the pediatric ED between April and July 2013 was consecutively and independently double triaged by two nurses, and the quadratic weighted kappa was estimated.

Results:

In the validity phase, the distribution of urgency levels in 1,416 visits was the following: 0.0% red (emergency); 5.9% orange (high urgency); 40.5% yellow (urgency); 50.6% green (low urgency); and 3.0% blue (no urgency). The percentage of patients who used two or more resources decreased from the orange level to the yellow, green, and blue levels (81%, 49%, 22%, and 2%, respectively, p<0.0001), as did the ED admission rate, ED length of stay, and hospitalization rate. The sensitivity to identify patients with high urgency level was 0.89 (confidence interval of 95% [95%CI] 0.78-0.95), and the undertriage rate was 7.4%. The inter-rater reliability in 191patients classified by two nurses was substantial (kw²=0.75; 95%CI 0.74-0.79).

Conclusions:

The CLARIPED system showed good validity and substantial reliability for triage in a pediatric emergency department.

Triage Performance in Emergency Medicine: A Systematic Review

STUDY OBJECTIVE

Rapid growth in emergency department (ED) triage literature has been accompanied by diversity in study design, methodology, and outcome assessment. We aim to synthesize existing ED triage literature by using a framework that enables performance comparisons and benchmarking across triage systems, with respect to clinical outcomes and reliability.

METHODS

PubMed, EMBASE, Scopus, and Web of Science were systematically searched for studies of adult ED triage systems through 2016. Studies evaluating triage systems with evidence of widespread adoption (Australian Triage Scale, Canadian Triage and Acuity Scale, Emergency Severity Index, Manchester Triage Scale, and South African Triage Scale) were cataloged and compared for performance in identifying patients at risk for mortality, critical illness and hospitalization, and interrater reliability. This study was performed and reported in adherence to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

RESULTS

A total of 6,160 publications were identified, with 182 meeting eligibility criteria and 50 with sufficient data for inclusion in comparative analysis. The Canadian Triage and Acuity Scale (32 studies), Emergency Severity Index (43), and Manchester Triage Scale (38) were the most frequently studied triage scales, and all demonstrated similar performance. Most studies (6 of 8) reported high sensitivity (>90%) of triage scales for identifying patients with ED mortality as high acuity at triage. However, sensitivity was low (<80%) for identification of patients who had critical illness outcomes and those who died within days of the ED visit or during the index hospitalization. Sensitivity varied by critical illness and was lower for severe sepsis (36% to 74%), pulmonary embolism (54%), and non-ST-segment elevation myocardial infarction (44% to 85%) compared with ST-segment elevation myocardial infarction (56% to 92%) and general outcomes of ICU admission (58% to 100%) and lifesaving intervention (77% to 98%). Some proportion of hospitalized patients (3% to 45%) were triaged to low acuity (level 4 to 5) in all studies. Reliability measures (κ) were variable across evaluations, with only a minority (11 of 42) reporting κ above 0.8.

CONCLUSION

We found that a substantial proportion of ED patients who die postencounter or are critically ill are not designated as high acuity at triage. Opportunity to improve interrater reliability and triage performance in identifying patients at risk of adverse outcome exists.

Initial assessment, level of care and outcome among children who were seen by emergency medical services: a prospective observational study

Background

The assessment of children in the Emergency Medical Service (EMS) is infrequent representing 5.4% of the patients in an urban area in the western part of Sweden. In Sweden, patients are assessed on scene by an EMS nurse whom independently decides on interventions and level of care. To aid the EMS nurse in the assessment a triage instrument, Rapid Emergency Triage and Treatment System-paediatrics (RETTS-p) developed for Emergency Department (ED) purpose has been in use the last 5 years. The aim of this study was to evaluate the EMS nurse assessment, management, the utilisation of RETTS-p and patient outcome.

Methods

A prospective, observational study was performed on 651 children aged < 16 years from January to December 2016. Statistical tests used in the study were Mann-Whitney U test, Fisher’s exact test and Spearman’s rank statistics.

Results

The dispatch centre indexed life-threatening priority in 69% of the missions but, of all children, only 6.1% were given a life threatening RETTS-p red colour by the EMS nurse. A total of 69.7% of the children were transported to the ED and, of these, 31.7% were discharged without any interventions. Among the non-conveyed patients, 16 of 197 (8.1%) visited the ED within 72 h but only two were hospitalised. Full triage, including five out of five vital signs measurements and an emergency severity index, was conducted in 37.6% of all children. A triage colour was not present in 146 children (22.4%), of which the majority were non-conveyed. The overall 30-day mortality rate was 0.8% (n = 5) in children 0–15 years.

Conclusions

Despite the incomplete use of all vital signs according to the RETTS-p, the EMS nurse assessment of children appears to be adapted to the clinical situation in most cases and the patients appear to be assessed to the appropriate level of care but indicating an over triage. It seems that the RETTS-p with full triage is used selectively in the pre-hospital assessment of children with a risk of death during the first 30 days of less than 1%.

Validity and Reliability of the Emergency Severity Index and Australasian Triage System in Pediatric Emergency Care of Mofid Children's Hospital in Iran

Objective:

To evaluate the validity, reliability, sensitivity, and specificity of the Emergency Severity Index (ESI) and Australasian Triage System (ATS) for children visiting admitted to the emergency department (ED).

Methods:

This was a prospective study occurred in the Mofid children's Hospital in Iran from August 2017 to November 2018 and children had aged ≤14 years and presented at the ED with a medical symptom were considered eligible for participation. This study was divided into two phases: in the first phase, we determined the inter-rater reliability of ESI version 4 and ATS by triage nurses and pediatric residents. In the second phase, to analyze the validity, sensitivity, and specificity of each triage system. Reliability and agreement rates were measured using kappa statistics.

Results:

ESI showed inter-rater reliability with kappa of 0.65–0.92 (P<0.001) and ATS showed inter-rater reliability with kappa of 0.51–0.87 ESI had sensitivity ranged from 81% to 95% and specificity ranged from 73% to 86%. In addition, sensitivity ranged of the ATS were 80% to 95% and specificity ranged from 74% to 87%. Under triage and over triage occurred in 12% and 15% of patients respectively in ESI and 13% and 15% of patients respectively in ATS.

Conclusion:

The ESI and ATS both valid to triage children in the ED section of Mofid children's Hospital paediatric. Reliability of the ESI is good, moderate to good for the ATS.

Pediatric Vital Sign Distribution Derived From a Multi-Centered Emergency Department Database

BACKGROUND

We hypothesized that current vital sign thresholds used in pediatric emergency department (ED) screening tools do not reflect observed vital signs in this population. We analyzed a large multi-centered database to develop heart rate (HR) and respiratory rate centile rankings and z-scores that could be incorporated into electronic health record ED screening tools and we compared our derived centiles to previously published centiles and Pediatric Advanced Life Support (PALS) vital sign thresholds.

METHODS

Initial HR and respiratory rate data entered into the Cerner™ electronic health record at 169 participating hospitals' ED over 5 years (2009 through 2013) as part of routine care were analyzed. Analysis was restricted to non-admitted children (0 to <18 years). Centile curves and z-scores were developed using generalized additive models for location, scale, and shape. A split-sample validation using two-thirds of the sample was compared with the remaining one-third. Centile values were compared with results from previous studies and guidelines.

RESULTS

HR and RR centiles and z-scores were determined from ~1.2 million records. Empirical 95th centiles for HR and respiratory rate were higher than previously published results and both deviated from PALS guideline recommendations.

CONCLUSION

Heart and respiratory rate centiles derived from a large real-world non-hospitalized ED pediatric population can inform the modification of electronic and paper-based screening tools to stratify children by the degree of deviation from normal for age rather than dichotomizing children into groups having "normal" versus "abnormal" vital signs. Furthermore, these centiles also may be useful in paper-based screening tools and bedside alarm limits for children in areas other than the ED and may establish improved alarm limits for bedside monitors.

Follow-up in patients with a burn-related emergency department visit: a feasibility study

Background

Data on epidemiology, costs, and outcomes of burn-related injuries presenting at emergency departments (EDs) are scarce. To obtain such information, a questionnaire study with an adequate response rate is imperative. There is evidence that optimized strategies can increase patient participation. However, it is unclear whether this applies to burn patients in an ED setting. The objective of this feasibility study was to optimize and evaluate patient recruitment strategy and follow-up methods in patients with burn injuries presenting at EDs.

Methods

In a prospective cohort study with a 6-month follow-up, patients with burn-related injuries attending two large EDs during a 3-month study period were included. Eligible patients were quasi-randomly allocated to a standard or optimized recruitment strategy by week of the ED visit. The standard recruitment strategy consisted of an invitation letter to participate, an informed consent form, a questionnaire, and a franked return envelope. The optimized recruitment strategy was complemented by a stamped returned envelope, monetary incentive, sending a second copy of the questionnaire, and a reminder by telephone in non-responders. Response rates were calculated, and questionnaires were used to assess treatment, costs, and health-related quality of life.

Results

A total of 87 patients were included of which 85 were eligible for the follow-up study. There was a higher response rate at 2 months in the optimized versus the standard recruitment strategy (43.6% vs. 20.0%; OR = 3.1 (95% CI 1.1–8.8)), although overall response is low. Non-response analyses showed no significant differences in patient, burn injury or treatment characteristics between responders versus non-responders.

Conclusions

This study demonstrated that response rates can be increased with an optimized, but more labor-intensive recruitment strategy, although further optimization of recruitment and follow-up is needed. It is feasible to assess epidemiology, treatment, and costs after burn-related ED contacts.

The Singapore Paediatric Triage Scale Validation Study

INTRODUCTION

This study aimed to determine the usefulness and validity of the triaging scale used in our emergency department (ED) by analysing its association with surrogate clinical outcome measures of severity consisting of hospitalisation rate, intensive care unit (ICU) admission, length of ED stay, predictive value for admission and length of hospitalisation.

METHODS

A retrospective observational study was conducted of the performance markers of the Singapore Paediatric Triage Scale (SPTS) to identify children who needed immediate and greater care. All children triaged and attended to at the paediatric ED at KK Women's and Children's Hospital, Singapore, from 1 January 2014 to 31 December 2014 were included. Data was retrieved from the Online Paediatric Emergency Care system, which is used for patients' care from initial triaging to final disposition.

RESULTS

Among 172,933 ED attendances, acuity levels 1, 2 plus, 2 and 3 were seen in 2.3%, 26.4%, 13.5% and 57.8% of patients, respectively. For admissions, triage acuity level 1 had a strong positive predictive value (79.5%), while triage acuity level 3 had a strong negative predictive value (93.7%). Fewer patients with triage acuity level 3 (6.3%) were admitted as compared to those with triage acuity level 1 (79.5%) (p < 0.001). There was a correlation between triage level and length of ED stay.

CONCLUSION

The SPTS is a valid tool for use in the paediatric emergency setting. This was supported by strong performance in important patient outcomes, such as admission to hospital, ICU admissions and length of ED stay.

Validity of triage systems for paediatric emergency care: a systematic review

AIM

To present a systematic review on the validity of triage systems for paediatric emergency care.

METHODS

Search in MEDLINE, Cochrane Library, Latin American and Caribbean Health Sciences Literature (LILACS), Scientific Electronic Library Online (SciELO), Nursing Database Index (BDENF) and Spanish Health Sciences Bibliographic Index (IBECS) for articles in English, French, Portuguese or Spanish with no time limit. Validity studies of five-level triage systems for patients 0-18 years old were included. Two reviewers performed data extraction and quality assessment as recommended by PRISMA statement.

RESULTS

We found 25 studies on seven triage systems: Manchester Triage System (MTS); paediatric version of Canadian Triage and Acuity Scale (PedCTAS) and its adaptation for Taiwan (paediatric version of the Taiwan Triage and Acuity System); Emergency Severity Index version 4 (ESI v.4); Soterion Rapid Triage System and South African Triage Scale and its adaptation for Bostwana (Princess Marina Triage Scale). Only studies on the MTS used a reference standard for urgency, while all systems were evaluated using a proxy outcome for urgency such as admission. Over half of all studies were low quality. The MTS, PedCTAS and ESI v.4 presented the largest number of moderate and high quality studies. The three tools performed better in their countries or near them, showing a consistent association with hospitalisation and resource utilisation. Studies of all three tools found that patients at the lowest urgency levels were hospitalised, reflecting undertriage.

CONCLUSIONS

There is some evidence to corroborate the validity of the MTS, PedCTAS and ESI v.4 for paediatric emergency care in their own countries or near them. Efforts to improve the sensitivity and to minimise the undertriage rates should continue. Cross-cultural adaptation is necessary when adopting these triage systems in other countries.

Five-level emergency triage systems: variation in assessment of validity

INTRODUCTION

Triage systems are scales developed to rate the degree of urgency among patients who arrive at EDs. A number of different scales are in use; however, the way in which they have been validated is inconsistent. Also, it is difficult to define a surrogate that accurately predicts urgency. This systematic review described reference standards and measures used in previous validation studies of five-level triage systems.

METHODS

We searched PubMed, EMBASE and CINAHL to identify studies that had assessed the validity of five-level triage systems and described the reference standards and measures applied in these studies. Studies were divided into those using criterion validity (reference standards developed by expert panels or triage systems already in use) and those using construct validity (prognosis, costs and resource use).

RESULTS

A total of 57 studies examined criterion and construct validity of 14 five-level triage systems. Criterion validity was examined by evaluating (1) agreement between the assigned degree of urgency with objective standard criteria (12 studies), (2) overtriage and undertriage (9 studies) and (3) sensitivity and specificity of triage systems (7 studies). Construct validity was examined by looking at (4) the associations between the assigned degree of urgency and measures gauged in EDs (48 studies) and (5) the associations between the assigned degree of urgency and measures gauged after hospitalisation (13 studies). Particularly, among 46 validation studies of the most commonly used triages (Canadian Triage and Acuity Scale, Emergency Severity Index and Manchester Triage System), 13 and 39 studies examined criterion and construct validity, respectively.

CONCLUSION

Previous studies applied various reference standards and measures to validate five-level triage systems. They either created their own reference standard or used a combination of severity/resource measures.

The danish regions pediatric triage model has a limited ability to detect both critically ill children as well as children to be sent home without treatment - a study of diagnostic accuracy

Background

The Danish Regions Pediatric Triage model (DRPT) was introduced in 2012 and subsequent implemented in most Danish acute pediatric departments. The aim was to evaluate the validity of DRPT as a screening tool to detect both the most serious acute conditions and the non-serious conditions in the acute referred patients in a pediatric department.

Method

The study was prospective observational, with follow-up on all children with acute referral to pediatric department from October to December 2015. The DRPT was evaluated by comparison to a predefined reference standard and to the actual clinical outcomes: critically ill children and children returned to home without any treatment. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy and likelihood for positive and negative test were calculated.

Results

Five hundred fifty children were included. The DRPT categorized 7% very urgent, 28% urgent, 29% standard and 36% non-urgent. The DRPT was equal to the reference standard in 31% of the children (CI: 27-35%). DRPT undertriaged 55% of the children (CI: 51-59%) and overtriaged 14% of the children (CI: 11-17%). For the most urgent patients the sensitivity of DRPT was 31% (CI: 20-48%) compared to the reference standard and 20% (CI: 7-41) for critically ill. For children with non-urgent conditions the specificity of DRPT was 66% (CI: 62-71%) compared to the reference standard and 68% (CI: 62-75%) for the children who went home with no treatment. In none of the analyses, the likelihood ratio of the negative test was less than 0.7 and the positive likelihood ratio only reached more than 5 in one of the analyses.

Discussion

This study is the first to evaluate the DRPT triage system. From the very limited validity studies of other well-established triage systems, it is difficult to judge whether the DRPT performs better or worse than the alternatives. The DRPT errs to the undertriage side. If the sensitivity is low, a number of the sickest children are undetected and this is a matter of concern.

Conclusion

The DRPT is a triage tool with limited ability to detect the critically ill children as well as the children who can be returned to home without any treatment.

Validation of different pediatric triage systems in the emergency department

BACKGROUND

Triage system in children seems to be more challenging compared to adults because of their different response to physiological and psychosocial stressors. This study aimed to determine the best triage system in the pediatric emergency department.

METHODS

This was a prospective observational study. This study was divided into two phases. The first phase determined the inter-rater reliability of five triage systems: Manchester Triage System (MTS), Emergency Severity Index (ESI) version 4, Pediatric Canadian Triage and Acuity Scale (CTAS), Australasian Triage Scale (ATS), and Ramathibodi Triage System (RTS) by triage nurses and pediatric residents. In the second phase, to analyze the validity of each triage system, patients were categorized as two groups, i.e., high acuity patients (triage level 1, 2) and low acuity patients (triage level 3, 4, and 5). Then we compared the triage acuity with actual admission.

RESULTS

In phase I, RTS illustrated almost perfect inter-rater reliability with kappa of 1.0 (P<0.01). ESI and CTAS illustrated good inter-rater reliability with kappa of 0.8-0.9 (P<0.01). Meanwhile, ATS and MTS illustrated moderate to good inter-rater reliability with kappa of 0.5-0.7 (P<0.01). In phase II, we included 1 041 participants with average age of 4.7±4.2 years, of which 55% were male and 45% were female. In addition 32% of the participants had underlying diseases, and 123 (11.8%) patients were admitted. We found that ESI illustrated the most appropriate predicting ability for admission with sensitivity of 52%, specificity of 81%, and AUC 0.78 (95%CI 0.74-0.81).

CONCLUSION

RTS illustrated almost perfect inter-rater reliability. Meanwhile, ESI and CTAS illustrated good inter-rater reliability. Finally, ESI illustrated the appropriate validity for triage system.

Safety of the Manchester Triage System to Detect Critically Ill Children at the Emergency Department

OBJECTIVE

To assess the safety of the Manchester Triage System in pediatric emergency care for children who require admission to the intensive care unit (ICU).

STUDY DESIGN

Between 2006 and 2013, 50 062 consecutive emergency department visits of children younger than the age of 16 years were included. We determined the percentage of undertriage, defined as the proportion of children admitted to ICU triaged as low urgent according to the Manchester Triage System, and diagnostic performance measures, including sensitivity, specificity, and diagnostic OR. Characteristics of undertriaged patients were compared with correctly triaged patients. In a logistic regression model, risk factors for undertriage were determined.

RESULTS

In total, 238 (28.7%) of the 830 children admitted to ICU during the study period were undertriaged. Sensitivity of high Manchester Triage System urgency levels to detect ICU admission was 71% (95% CI 68%-74%) and specificity 85% (95% CI 85%-85%). Severity of illness was lower in undertriaged children than correctly triaged children admitted to ICU. Risk factors for undertriage were age <3 months, medical presenting problem, comorbidity, referral by a medical specialist or emergency medical services, and presentation during the evening or night shift.

CONCLUSION

The Manchester Triage System misclassifies a substantial number of children who require ICU admission. Modifications targeted at young children and children with a comorbid condition could possibly improve safety of the Manchester Triage System in pediatric emergency care.

Manchester Triage System: main flowcharts, discriminators and outcomes of a pediatric emergency care

Objetive:

to characterize the care services performed through risk rating by the Manchester Triage System, identifying demographics (age, gender), main flowcharts, discriminators and outcomes in pediatric emergency

Method:

cross-sectional quantitative study. Data on risk classification were obtained through a search of computerized registration data from medical records of patients treated in the pediatric emergency within one year. Descriptive statistics with absolute and relative frequencies was used for the analysis.

Results:

10,921 visits were conducted in the pediatric emergency, mostly male (54.4%), aged between 29 days and two years (44.5%). There was a prevalence of the urgent risk category (43.6%). The main flowchart used in the care was worried parents (22.4%) and the most prevalent discriminator was recent event (15.3%). The hospitalization outcome occurred in 10.4% of care performed in the pediatric emergency, however 61.8% of care needed to stay under observation and / or being under the health team care in the pediatric emergency.

Conclusion:

worried parents was the main flowchart used and recent events the most prevalent discriminator, comprising the hospitalization outcomes and permanency in observation in the pediatric emergency before discharge from the hospital.

Scoring systems in paediatric emergency care: Panacea or paper exercise?

Scoring systems to recognise the most ill patients, or those at risk of deterioration, are increasingly utilised in hospitals that look after paediatric inpatients. There have been efforts to implement these systems in emergency and urgent care settings, but they have yet unproven value. This is because the child or young person presenting acutely is a different cohort than the 'treated' ward-based group. The majority of children presenting to emergency and urgent care settings are discharged home, and so, scoring systems need to recognise the most unwell but also assist in safe and appropriate discharge as well as highlighting those patients in need of more senior review. This article explores this conundrum, suggesting how cognitive factors have a role to play, and how scoring systems can have wider effects than just individual patient care.

Validation of pediatric early warning score in pediatric emergency department

BACKGROUND

One of the most important functions of the emergency department (ED) is to assess patient status. Only one, the pediatric early warning score (PEWS), has been designed for ED with acceptable validity, but it has never been validated in Thailand. The objective of this study was to validate PEWS in predicting hospitalization in children visiting the ED.

METHODS

During the initial phase, two triage nurses performed blind scoring (in order to determine inter-rater reliability using kappa statistics) for the first 30 patients who presented to the ED at Ramathibodi Hospital between March and May 2014 and who were aged < 15 years. The second phase then consisted of validation and involved 1136 patients. Patients who presented with trauma, psychiatric, dental and surgical concerns were excluded. Validity of the scoring system in predicting admission was assessed using area under the receiver operating characteristics (ROC) curve (AUC), sensitivity, and specificity, positive predictive value (PPV) and negative predictive value (NPV).

RESULTS

Phase I demonstrated good inter-rater reliability (kappa = 0.75). In phase II, of the total group of 1136 patients, 168 patients (14.8%) were admitted: 162 to the general ward and six to the intensive care unit (ICU) during the study period. AUC for predicting overall, ICU, and general ward admission were 0.73 (95%CI: 0.68-0.77), 0.98 (95%CI: 0.96-1) and 0.71 (95%CI: 0.66-0.75), respectively. The sensitivity and specificity in predicting overall admission with a cut-off of PEWS ≥ 1 was 78% and 60%, respectively (PPV, 28%; NPV, 95%). Sensitivity and specificity in predicting ICU admission with the cut-off PEWS ≥ 3 was 100% and 91%, respectively (PPV, 5%; NPV, 100%). Using the cut-off PEWS ≥ 1, sensitivity and specificity in predicting ward admission were 77% and 59%, respectively (PPV, 24%; NPV, 94%).

CONCLUSION

PEWS can be helpful in assessing patient status in pediatric ED with acceptable validity and can serve as a potentially excellent screening tool for prediction of ICU admission.

Impact of a clinical decision model for febrile children at risk for serious bacterial infections at the emergency department: a randomized controlled trial

OBJECTIVES

To assess the impact of a clinical decision model for febrile children at risk for serious bacterial infections (SBI) attending the emergency department (ED).

METHODS

Randomized controlled trial with 439 febrile children, aged 1 month-16 years, attending the pediatric ED of a Dutch university hospital during 2010-2012. Febrile children were randomly assigned to the intervention (clinical decision model; n = 219) or the control group (usual care; n = 220). The clinical decision model included clinical symptoms, vital signs, and C-reactive protein and provided high/low-risks for "pneumonia" and "other SBI". Nurses were guided by the intervention to initiate additional tests for high-risk children. The clinical decision model was evaluated by 1) area-under-the-receiver-operating-characteristic-curve (AUC) to indicate discriminative ability and 2) feasibility, to measure nurses' compliance to model recommendations. Primary patient outcome was defined as correct SBI diagnoses. Secondary process outcomes were defined as length of stay; diagnostic tests; antibiotic treatment; hospital admission; revisits and medical costs.

RESULTS

The decision model had good discriminative ability for both pneumonia (n = 33; AUC 0.83 (95% CI 0.75-0.90)) and other SBI (n = 22; AUC 0.81 (95% CI 0.72-0.90)). Compliance to model recommendations was high (86%). No differences in correct SBI determination were observed. Application of the clinical decision model resulted in less full-blood-counts (14% vs. 22%, p-value < 0.05) and more urine-dipstick testing (71% vs. 61%, p-value < 0.05).

CONCLUSIONS

In contrast to our expectations no substantial impact on patient outcome was perceived. The clinical decision model preserved, however, good discriminatory ability to detect SBI, achieved good compliance among nurses and resulted in a more standardized diagnostic approach towards febrile children, with less full blood-counts and more rightfully urine-dipstick testing.

Validity of the Canadian Paediatric Triage and Acuity Scale in a tertiary care hospital

Objective:

We evaluated the validity of the Canadian Paediatric Triage and Acuity Scale (Paed-CTAS) for children visiting a pediatric emergency department (ED).

Methods:

This was a retrospective study evaluating all children who presented to a pediatric university-affiliated ED during a 1-year period. Data were retrieved from the ED database. Information regarding triage and disposition was registered in an ED database by a clerk following patient management. In the absence of a gold standard for triage, admission to hospital, admission to pediatric intensive care unit (PICU) and length of stay (LOS) in the ED were used as surrogate markers of severity. The primary outcome measure was the correlation between triage level (from 1 to 5) and admission to hospital. The correlation between triage level and dichotomous outcomes was evaluated by aχ2test and an analysis of variance (ANOVA) was used to evaluate the association between triage level and ED LOS.

Results:

Over the 1-year period, 58 529 patients were triaged in the ED. The proportion admitted to hospital was 63% for resuscitation (level 1), 37% for emergent (level 2), 14% for urgent (level 3), 2% for semiurgent (level 4) and 1% for nonurgent (level 5) (p&lt; 0.001). There was also a good correlation between triage levels and LOS and admission to PICU (bothp&lt; 0.001).

Conclusion:

This computerized version of PaedCTAS demonstrates a strong association with admission to hospital, admission to PICU and LOS in the ED. These results suggest that PaedCTAS is a valid tool for triage of children in a pediatric ED.

Scientific Literature on the Reliability and Validity of the Manchester Triage System (MTS) Protocol: A Integrative Literature Review

OBJECTIVE To analyze the scientific production about the validity and reliability of the Manchester Triage System (MTS) protocol. METHOD A descriptive study of an integrative literature review. Articles on the validity and reliability of the MTS developed with children and adults published between 1999 and 2013 were included. RESULTS 14 articles were selected from a total of 8438, nine of validity and five of reliability. The reliability of the MTS ranged from moderate to almost perfect, with higher intra-evaluation. Regarding validity, the results seem to point to equivalent and satisfactory sensibility and specificity levels of the MTS. The instrument proved to be a good predictor of the need for hospitalization and of hospital mortality. CONCLUSION The reliability and validity of the MTS obtained in the studies is varied. It is recommended that new studies indicate necessary modifications to the MTS so that it is more safely used by nurses.

Predicting patient disposition in a paediatric emergency department

AIM

The aim of this study is to directly compare published prediction tools with triage nurse (TN) predictions within a defined paediatric population.

METHOD

A prospective observational study carried out over a week in May 2010 in the Emergency Department (ED) at Princess Margaret Hospital for Children in Perth, Western Australia. TN predicted which patients would be admitted to hospital at the time of ED presentation. Data required for the other prediction tools (paediatric early warning score (PEWS); triage category and the Pediatric Risk of Admission Score (PRISA) and PRISA II were obtained from the notes following the patient's ED attendance.

RESULTS

A total of 1223 patients presented during the study week, 91 patients were excluded and a total of 946 patients (83.6%) had TN predictions and were included in the analysis. TN predictions were compared against a PEWS ≥ 4, triage category 1, 2 and 3, PRISA ≥ 9 and PRISA II ≥ 2. TNs had the highest prediction accuracy (87.7%), followed by an elevated PEWS (82.9%), triage category of 1, 2, or 3 (82.9%). The PRISA and PRISA II score had an accuracy of 80.1% and 79.7%, respectively.

CONCLUSION

When compared with validated prediction tools, the TN is the most accurate predictor of need to admit. This study provides valuable information in planning efficient flow of patients through the ED.

Efficacy of the Manchester Triage System: a systematic review

INTRODUCTION

The growing number of patients in emergency departments can lead to overcrowding, often adding to organisational problems. Triage aims to predict the severity of disease, with the aim of organising patient flow. The aim of this study was to analyse the efficacy of the Manchester Triage System (MTS) for risk classification of patients.

METHODS

A systematic review of the literature in Ebscohost, Pubmed and Scielo (2002-2013) was undertaken. Articles were selected independently by two researchers using selection criteria. Twenty-two articles were selected for inclusion in this review.

RESULTS

The results support the applicability of the MTS, which has proven validity for use in children, adults, patients with coronary syndrome and patients with acute pulmonary embolism. The MTS was found to be inclusive, and to predict emergency department admission and death in the short term.

CONCLUSION

The majority of studies found that the MTS was useful in triage of patients in emergency departments, but sub-triage and super-triage (i.e. under and over classification of severity, respectively) still occur.

A systematic review on the validity and reliability of an emergency department triage scale, the Manchester Triage System

OBJECTIVE

To conduct a systematic review to check the level of validity and reliability of the Manchester Triage System and the quality of reporting of literature on this topic.

DESIGN

This is a systematic review based on the PRISMA guideline on reporting systematic reviews.

DATA SOURCES

The systematic search of the international literature published from 1997 through 30 November 2012 in the PubMed, Embase, Cochrane Library, Cinahl, Web of Knowledge, and Scopus databases.

REVIEW METHODS

This review included quantitative and qualitative research investigating the reliability and validity of the Manchester Triage System for the broad population of adults and children visiting the emergency department. After a systematic selection process, included studies were assessed on their quality by three researchers using the STARD guidelines.

RESULTS

Twelve studies were included in the review. The studies investigated the inter- and intra-rater reliability using the "kappa" statistic; the validity was tested with many measures: validity in predicting mortality, hospital admission, under- and overtriage, used resources, and length of stay in the emergency department, as well as a reference standard rating.

CONCLUSIONS

In this review, the Manchester Triage System shows a wide inter-rater agreement range with a prevalence of good and very good agreement. Its safety was low because of the high rate of undertriage and the low sensitivity in predicting higher urgency levels. The high rate of overtriage could cause unnecessarily high use of resources in the emergency department. The quality of the reporting in studies of the reliability and validity of the Manchester Triage System is good.

EDs of two hospitals in The Netherlands (2006–2009), one in Portugal (November–December 2010), and one in UK (June–November 2010).

Patients

Children (<16years) triaged with the MTS who presented at the ED.

Methods

Changes to discriminators (MTS 1) and the value of including abnormal vital signs (MTS 2) were studied to test if this would decrease the number of incorrect assignment. Admission to hospital using the new MTS was compared with those in the original MTS. Likelihood ratios, diagnostic odds ratios (DORs), and c-statistics were calculated as measures for performance and compared with the original MTS. To calculate likelihood ratios and DORs, the MTS had to be dichotomized in low urgent and high urgent.

Results

60,375 patients were included, of whom 13% were admitted. When MTS 1 was used, admission to hospital increased from 25% to 29% for MTS ‘very urgent’ patients and remained similar in lower MTS urgency levels. The diagnostic odds ratio improved from 4.8 (95%CI 4.5–5.1) to 6.2 (95%CI 5.9–6.6) and the c-statistic remained 0.74. MTS 2 did not improve the performance of the MTS.

Conclusions

MTS 1 performed slightly better than the original MTS. The use of vital signs (MTS 2) did not improve the MTS performance.

Inter-Rater Agreement of Emergency Nurses and Physicians in Emergency Severity Index (ESI) Triage

INTRODUCTION

Triage is one of the most important systems in patients prioritizing at the time of arrival to hospital. Based on the severity of the injury and the need for treatment, this system manages patients in the least time, which could lead to rotation of patients with high reliability and safety. Currently, the most accepted method for triage is emergency severity index (ESI) system, considered as five-level triage method, too. This method were implemented in Al Zahra Hospital of Isfahan by trained nurses since March to May 2010. This study was aimed to evaluate the accuracy of emergency nursing triage using ESI.

METHODS

This prospective cross sectional study was carried out on 601 patients referred to Al-Zahra hospital of Isfahan through May 2010. The patients' triage level were determined by physicians and nurses separately and the results compared. To define the level of agreement between two groups (inter-rater agreement), the kappa index was evaluated. To specify the association between the time interval of initial triage and patient final status, Chi-Square test was applied using SPSS 18 statistical software.

RESULTS

There was no significant difference between results of nurses and physicians triage (P<0/0001). The agreement level (kappa index) between two groups was 94% (95% CI: 0.931-0.957). Of 601 patients, 44.1% ones were hospitalized at the emergency department, 52.6% discharged and 3.3% died. The average of time interval between nursing triage and physician visit was 9.55 minutes at the level one triage, 21.64 minutes at level two, 26.03 minutes at level three, 26.93 minutes at level four, and 11.70 minutes at level five.

CONCLUSION

It seems that there is an acceptable inter-rater agreement between emergency nurses and physicians regarding patients' triage in terms of ESI system.

[Interdisciplinary emergency departments : first experiences from the ENT and head and neck perspective]

BACKGROUND

Centralized emergency departments are becoming a major source of health care in Germany. In this study, we evaluated the importance for ENT health care.

METHODS

In a retrospective study, all ENT emergency patients between May and July 2011 were characterized by diagnosis, therapy, and urgency (measured using the Manchester Triage System [MTS]). General epidemiological data from the emergency department were recorded between 2009 and 2011.

RESULTS

Between 2009 and 2011, 50,699 patients were treated in the centralized emergency department of the University Hospital Bonn. A total of 15,658 (30.8%) needed ENT health care. During May 2011 to July 2011, ENT emergency patients had not only a wide variety of diseases but also a broad range of ages (0-98 years). Using the MTS, emergency patients (4% acute emergencies) were identified and urgency was determined prior to first contact with the physician.

CONCLUSION

ENT emergency care plays an important role for centralized emergency departments. Most of the patients have ENT diseases treatable as an outpatient in a single visit. MTS can be used to determine the appropriate level of urgency.
