Background. Few studies have focused on the agreement level of pediatric triage scales (PTSs). The aim of this meta-analytic review was to examine the level of inter-rater reliability of PTSs. Methods. Detailed searches of a number of electronic databases were performed up to 1 March 2019. Studies that reported sample sizes, reliability coefficients, and a comprehensive description of the assessment of the inter-rater reliability of PTSs were included. The articles were selected according to the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) taxonomy. Two reviewers were involved in the study selection, quality assessment, and data extraction and performed the review process. The effect size was estimated by z-transformation of reliability coefficients. Data were pooled with random-effects models, and a metaregression analysis was performed based on the method of moments estimator. Results. Thirteen studies were included. The pooled coefficient for the level of agreement was 0.727 (confidence interval (CI) 95%: 0.650–0.790). The level of agreement on PTSs was substantial, with a value of 0.25 (95% CI: 0.202–0.297) for the Australasian Triage Scale (ATS), 0.571 (95% CI: 0.372–0.720) for the Canadian Triage and Acuity Scale (CTAS), 0.810 (95% CI: 0.711–0.877) for the Emergency Severity Index (ESI), and 0.755 (95% CI: 0.522–0.883) for the Manchester Triage System (MTS). Conclusions. Overall, the reliability of pediatric triage systems was substantial, and this level of agreement should be considered acceptable for triage in the pediatric emergency department. Further studies on the level of agreement of pediatric triage systems are needed.

Introduction It is unclear whether the Emergency Severity Index (ESI) can identify high-risk patients with Chronic Obstructive Pulmonary Disease (COPD). This study aims to compare the mistriage rates of the ESI plus the Peak Expiratory Flowmeter (PEF) approach and ESI approach among dyspneic patients with COPD. Methods This study was a randomized clinical trial conducted between July and October 2018. We randomly assigned COPD patients with dyspnea to the ESI + PEF or ESI groups. Triage levels, disposition rates, number of resources used, and time to first physician contact were compared in patients admitted to the Intensive Care Unit (ICU), the Pulmonary Care Unit (PU), or discharged from the ED. Reliability of the ESI was evaluated by using the interobserver agreement (Kappa). Results Seventy COPD patients were equally assigned to the ESI + PEF and ESI groups. The under-triage rates were 11.42% and 0%, the over-triage rates were 31.42% and 2.85% in the ESI and ESI + PEF groups, respectively. The triage levels of the patients admitted to the ICU (2 vs. 3), the PU (2 vs. 4), or discharged from the ED (3 vs. 2) were significantly different between the ESI + PEF and ESI groups. Conclusions Addition of PEF to the ESI provides a more accurate method for triaging COPD patients compared to ESI alone. We recommend using PEF for the triage of COPD patients in the ED.
