Chen JY, Hsieh CC, Lee JT, Lin CH, Kao CY. Patient stratification based on the risk of severe illness in emergency departments through collaborative machine learning models. Am J Emerg Med 2024; 82:142-152. [PMID: 38908339 DOI: 10.1016/j.ajem.2024.06.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 04/18/2024] [Accepted: 06/07/2024] [Indexed: 06/24/2024] Open
Abstract
OBJECTIVES Emergency department (ED) overcrowding presents a global challenge that inhibits prompt care for critically ill patients. Traditional 5-level triage system that heavily rely on the judgment of the triage staff could fail to detect subtle symptoms in critical patients, thus leading to delayed treatment. Unlike previous rivalry-focused approaches, our study aimed to establish a collaborative machine learning (ML) model that renders risk scores for severe illness, which may assist the triage staff to provide a better patient stratification for timely critical cares. METHODS This retrospective study was conducted at a tertiary teaching hospital. Data were collected from January 2015 to October 2022. Demographic and clinical information were collected at triage. The study focused on severe illness as the outcome. We developed artificial neural network (ANN) models, with or without utilizing the Taiwan Triage and Acuity Scale (TTAS) score as one of the predictors. The model using the TTAS score is termed a machine-human collaborative model (ANN-MH), while the model without it is referred to as a machine-only model (ANN-MO). The predictive power of these models was assessed using the area under the receiver-operating-characteristic (AUROC) and the precision-recall curves (AUPRC); their sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and F1 score were compared. RESULTS The study analyzed 668,602 ED visits from 2015 to 2022. Among them, 278,724 visits from 2015 to 2018 were used for model training and validation, while 320,201 visits from 2019 to 2022 were for testing model performance. Approximately 2.6% of visits were by severely ill patients, whose TTAS scores ranged from 1 to 5. The ANN-MH model achieved a testing AUROC of 0.918 and AUPRC of 0.369, while for the ANN-MO model the AUROC and AUPRC were 0.909 and 0.339, respectively. Based on these metrics, the ANN-MH model outperformed the ANN-MO model, and both surpassed human triage classification. Subgroup analyses further highlighted the models' capability to identify higher-risk patients within the same triage level. CONCLUSIONS The traditional 5-level triage system often falls short, leading to under-triage of critical patients. Our models include a score-based differentiation within a triage level to offer advanced risk stratification, thereby promoting patient safety.

Use of Reverse Shock Index Multiplied by Simplified Motor Score in a Five-Level Triage System: Identifying Trauma in Adult Patients at a High Risk of Mortality. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:647. [PMID: 38674293 PMCID: PMC11052466 DOI: 10.3390/medicina60040647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Revised: 04/12/2024] [Accepted: 04/14/2024] [Indexed: 04/28/2024]
Abstract
Background and Objectives: The Taiwan Triage and Acuity Scale (TTAS) is reliable for triaging patients in emergency departments in Taiwan; however, most triage decisions are still based on chief complaints. The reverse-shock index (SI) multiplied by the simplified motor score (rSI-sMS) is a more comprehensive approach to triage that combines the SI and a modified consciousness assessment. We investigated the combination of the TTAS and rSI-sMS for triage compared with either parameter alone as well as the SI and modified SI. Materials and Methods: We analyzed 13,144 patients with trauma from the Taipei Tzu Chi Trauma Database. We investigated the prioritization performance of the TTAS, rSI-sMS, and their combination. A subgroup analysis was performed to evaluate the trends in all clinical outcomes for different rSI-sMS values. The sensitivity and specificity of rSI-sMS were investigated at a cutoff value of 4 (based on previous study and the highest score of the Youden Index) in predicting injury severity clinical outcomes under the TTAS system were also investigated. Results: Compared with patients in triage level III, those in triage levels I and II had higher odds ratios for major injury (as indicated by revised trauma score < 7 and injury severity score [ISS] ≥ 16), intensive care unit (ICU) admission, prolonged ICU stay (≥14 days), prolonged hospital stay (≥30 days), and mortality. In all three triage levels, the rSI-sMS < 4 group had severe injury and worse outcomes than the rSI-sMS ≥ 4 group. The TTAS and rSI-sMS had higher area under the receiver operating characteristic curves (AUROCs) for mortality, ICU admission, prolonged ICU stay, and prolonged hospital stay than the SI and modified SI. The combination of the TTAS and rSI-sMS had the highest AUROC for all clinical outcomes. The prediction performance of rSI-sMS < 4 for major injury (ISS ≥ 16) exhibited 81.49% specificity in triage levels I and II and 87.6% specificity in triage level III. The specificity for mortality was 79.2% in triage levels I and II and 87.4% in triage level III. Conclusions: The combination of rSI-sMS and the TTAS yielded superior prioritization performance to TTAS alone. The integration of rSI-sMS and TTAS effectively enhances the efficiency and accuracy of identifying trauma patients at a high risk of mortality.

Lau T, Maltby A, Ali S, Moran V, Wilk P. Does the definition of preventable emergency department visit matter? An empirical analysis using 20 million visits in Ontario and Alberta. Acad Emerg Med 2022; 29:1329-1337. [PMID: 36043233 DOI: 10.1111/acem.14587] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 08/11/2022] [Accepted: 08/28/2022] [Indexed: 01/25/2023]
Abstract
OBJECTIVES This study had two objectives: (1) to estimate the prevalence of preventable emergency department (ED) visits during the 2016-2020 time period among those living in 19 large urban centers in Alberta and Ontario, Canada, and (2) to assess if the definition of preventable ED visits matters in estimating the prevalence. METHODS A retrospective, population-based study of ED visits that were reported to the National Ambulatory Care Reporting System from April 1, 2016, to March 31, 2020, was conducted. Preventable ED visits were operationalized based on the following approaches: (1) Canadian Triage and Acuity Scale (CTAS), (2) ambulatory care-sensitive conditions (ACSC), (3) family practice-sensitive conditions (FPSC), and (4) sentinel nonurgent conditions (SNC). The overall proportion of ED visits that were preventable was estimated. We also estimated the adjusted relative risks of preventable ED visits by patients' sex and age, fiscal year, province of residence, and census metropolitan area (CMA) of residence. RESULTS There were 20,171,319 ED visits made by 8,919,618 patients ages 1 to 74 who resided in one of the 19 CMAs in Alberta or Ontario. On average, there were 2.26 visits per patient over the period of 4 fiscal years; most patients made one (44.22%) or two ED visits (20.72%). The overall unadjusted prevalence of preventable ED visits varied by definition; 35.33% of ED visits were defined as preventable based on CTAS, 12.88% based on FPSC, 3.41% based on SNC, and 2.33% based on ACSC. CONCLUSIONS There is a substantial level of variation in prevalence estimates across definitions of preventable ED visits, and care should be taken when interpreting these estimates as each has a different meaning and may lead to different conclusions. The conceptualization and measurement of preventable ED visits is complex and multifaceted and may not be adequately captured by a single definition.

Impact of COVID-19 Pandemic on Emergency Department Volume and Acuity in Low Incidence Area: Taiwan's Experience in Three Hospitals. J Acute Med 2022; 12:105-112. [PMID: 36313608 PMCID: PMC9561484 DOI: 10.6705/j.jacme.202209_12(3).0003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 10/08/2021] [Accepted: 11/12/2021] [Indexed: 06/16/2023]
Abstract
BACKGROUND The decrease in emergency department (ED) patient visits during the COVID-19 pandemic was reported by various studies. Our study aimed to investigate whether a similar trend can be observed in a country with a low incidence of COVID-19 as well as the impact caused by the pandemic on ED patients in different triage levels and categories. METHODS This multicenter retrospective study collected data from three regional hospitals between March 2019 and December 2020. We evaluated the differences between patient volume, disease severity, and patient composition in ED before and after the COVID-19 pandemic among these hospitals. RESULTS There was a 23% reduction in ED patient volume in the urban hospital (hospital A) as well as a 16% reduction in suburban hospitals (hospitals B and C) during the pandemic period, respectively. The regression analysis showed a high correlation in the change in monthly patient volume among these hospitals. In terms of severity, there was a 24% reduction in ED visits with high severity levels (Taiwan Triage and Acuity Scale [TTAS] I, II) in hospital A, as well as 16% and 12% in hospitals B and C during the pandemic period, respectively. Similarly, there was a 23% reduction in ED visits with low severity levels (TTAS III, IV, V) in hospital A, as well as 20% and 16% in hospitals B and C during the pandemic period, respectively. In terms of patient types, there was a significant decline in non-traumatic adult patients (19%, 17%, and 10%), and pediatric patients (49%, 50%, and 46%) in hospitals A, B, and C, respectively. CONCLUSIONS Despite the low incidence of COVID-19 in Taiwan, a decrease in total ED visits was still found during the pandemic, especially in non-trauma adult visits and pediatric visits. In addition, ED visits in both high and low severity levels decreased in these regional hospitals.

Machine learning-based triage to identify low-severity patients with a short discharge length of stay in emergency department. BMC Emerg Med 2022; 22:88. [PMID: 35596154 PMCID: PMC9123815 DOI: 10.1186/s12873-022-00632-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Accepted: 04/14/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Overcrowding in emergency departments (ED) is a critical problem worldwide, and streaming can alleviate crowding to improve patient flows. Among triage scales, patients labeled as "triage level 3" or "urgent" generally comprise the majority, but there is no uniform criterion for classifying low-severity patients in this diverse population. Our aim is to establish a machine learning model for prediction of low-severity patients with short discharge length of stay (DLOS) in ED. METHODS This was a retrospective study in the ED of China Medical University Hospital (CMUH) and Asia University Hospital (AUH) in Taiwan. Adult patients (aged over 20 years) with Taiwan Triage Acuity Scale level 3 were enrolled between 2018 and 2019. We used available information during triage to establish a machine learning model that can predict low-severity patients with short DLOS. To achieve this goal, we trained five models-CatBoost, XGBoost, decision tree, random forest, and logistic regression-by using large ED visit data and examined their performance in internal and external validation. RESULTS For internal validation in CMUH, 33,986 patients (75.9%) had a short DLOS (shorter than 4 h), and for external validation in AUH, there were 13,269 (82.7%) patients with short DLOS. The best prediction model was CatBoost in internal validation, and area under the receiver operating cha racteristic curve (AUC) was 0.755 (95% confidence interval (CI): 0.743-0.767). Under the same threshold, XGBoost yielded the best performance, with an AUC value of 0.761 (95% CI: 0.742- 0.765) in external validation. CONCLUSIONS This is the first study to establish a machine learning model by applying triage information alone for prediction of short DLOS in ED with both internal and external validation. In future work, the models could be developed as an assisting tool in real-time triage to identify low-severity patients as fast track candidates.

Abstract
Today, the concomitant abuse of nitrous oxide (N2O) and illicit drugs is evident and problematic. However, there are few reports regarding the clinical manifestations of N2O users when they present to the emergency department (ED). The purpose of this study was to describe the clinical presentations, the associated illicit substances used in combination, and the outcomes in N2O users visiting the ED. This was a retrospective observational cohort study. All N2O adult users admitted to the ED at Linkou Chang Gung Memorial Hospital between 2012 and 2020 were included. Demographic variables, clinical symptoms, and examination results were collected from medical records. Univariate comparisons were conducted between pure N2O users and combined illicit drug users. A total of 40 patients were included, 24 of which were pure N2O users. Limb weakness and numbness accounted for the majority of chief complaints. Neurologic symptoms were the most common clinical manifestations (90%). A more severe ED triage level, faster heart rate, greater agitation, and cardiovascular symptoms were significantly noted in combined illicit drug users. In ED, limb numbness/weakness should arouse physicians’ awareness of patients using N2O. Combined use of N2O and illicit drugs can cause great harm to health.

Abstract
Emergency triage is crucial for the treatment and prognosis of emergency patients, but its validity needs further improvement. The purpose of this study was to identify a risk score for adult triage. We conducted a regression analysis of physiological and biochemical data from 1,522 adult patients. A 60-point triage scoring model included temperature, pulse, systolic blood pressure, oxygen saturation, consciousness, dyspnea, admission mode, syncope history, chest pain or chest tightness, complexion, hematochezia or hematemesis, hemoptysis, white blood count, creatinine, bicarbonate, platelets, and creatine kinase. The area under curve in predicting ICU admission was 0.929 (95% CI [0.913-0.944]) for the derivation cohort and 0.911 (95% CI [0.884-0.938]) for the validation cohort. Four categories: critical level (≥13 points), severe level (6-12 points), urgency level (1-5 points), and sub-acute level (0 points) were divided, which significantly distinguished the severity of emergency patients.

Abstract
Investigation of physician-related causes of unscheduled revisits to the emergency department (ED) within 72 h with subsequent admission to the intensive care unit (ICU) is an important parameter of emergency care quality. Between 2012 and 2017, medical records of all adult patients who visited the ED and returned within 72 h with subsequent ICU admission were retrospectively reviewed by three experienced emergency physicians. Study parameters were categorized into "input" (Patient characteristics), "throughput" (Time spent on first ED visit and seniority of emergency physicians, and "output" (Charlson Comorbidity Index). Of the 147 patients reviewed for the causes of ICU admission, 35 were physician-related (23.8%). Eight belonged to more urgent categories, whereas the majority (n = 27) were less urgent. Patients who spent less time on their first ED visits before discharge (< 2 h) were significantly associated with physician-related causes of ICU admission, whereas there was no significant difference in other "input," "throughput," and "output" parameters between the "physician-related" and "non-physician-related" groups. Short initial management time was associated with physician-related causes of ICU admission in patients with initial less urgent presentations, highlighting failure of the conventional triage system to identify potentially life-threatening conditions and possibility of misjudgement because of the patients' apparently minor initial presentations.

Abstract
AIM To measure and compare the reliability and validity of three international triage systems (CTAS, MTS and ESI) when applied to patient presentations in the emergency centres of a private health-care group in the United Arab Emirates. BACKGROUND The ability of triage systems to sort patients into categories based on the urgency of their need and time to physician is a key indicator. Three international triage systems are being used for this purpose in private emergency centre settings. METHOD Bespoke reference scenarios, 50 vignettes (10 per severity level) were created and validated by a local expert panel. Nurses performing triage at four emergency centres in the Emirate of Dubai completed online surveys to categorise the vignettes based on the triage system they used in their emergency centre. RESULTS Overall inter-rater reliability per triage category was substantial for allocations in category one, moderate for those in categories two and five, and fair for those in categories three and four. Agreement between raters and the reference standard was consistent throughout all four emergency centres. The accuracy of triaging allocations into categories one, two and five were good, whereas allocations in categories three and four were less accurate. CONCLUSION International triage systems focus on the identification of more urgent cases and perform poorly in discriminating between those that are less serious, which is less ideal in a setting where less-serious cases are more prevalent.

Abstract
BACKGROUND Communication skills may be an important skill for the front-line emergency physicians. AIM This study aimed to investigate the effect of training in a SHARE communication course by emergency physicians on patient notification and signing of do-not-resuscitate (DNR) orders for critical patients in the emergency room. DESIGN From a total of 29 attending physicians in the emergency department, 19 physicians had been trained in the SHARE communication course. An observation form designed based on the SHARE training was completed by two observers who noted the communication process between physicians and patients and family members during patient notification and signing a DNR order. To assess the influence of physicians trained in a SHARE communication course on the signing of DNR orders, a propensity score-matched population was created to reduce the potential selection bias of patients and family members. SETTING Level 1 trauma medical center in southern Taiwan. RESULTS There were 145 individuals enrolled in the study, of which 93 signed the DNR order, and 52 did not sign it. Analysis from 23 matched pairs from this population revealed that significantly more family members would sign a DNR order if the physician had been trained in the SHARE communication course than when they did not receive this training (78.3% vs. 39.1%, respectively, p = 0.017). The overall score of the observation form for physicians was higher in those individuals who had signed a DNR order than in those who did not sign it (29.48 ± 3.72 vs. 26.13 ± 3.52, respectively, p = 0.003), especially when the physician had chosen a quiet environment (1.35 ± 0.65 vs. 0.87 ± 0.69, respectively, p = 0.020), understood the patient's wishes and confirmed them (1.78 ± 0.42 vs. 1.30 ± 0.70, respectively, p = 0.008), and expressed concern (1.48 ± 0.79 vs. 0.96 ± 0.77, respectively, p = 0.028). In addition, a feedback survey about the feelings experienced by these physicians during the process of patient notification did not reveal a significant difference during the communication with those who had or had not signed DNR orders. CONCLUSION The training in a SHARE communication course can improve the communication skills of emergency physicians in patient notification and signing of DNR orders for critical patients.

Abstract
OBJECTIVE To assess and compare the performance of triage systems for identifying high and low-urgency patients in the emergency department (ED). DESIGN Systematic review and meta-analysis. DATA SOURCES EMBASE, Medline OvidSP, Cochrane central, Web of science and CINAHL databases from 1980 to 2016 with the final update in December 2018. ELIGIBILITY CRITERIA Studies that evaluated an emergency medical triage system, assessed validity using any reference standard as proxy for true patient urgency and were written in English. Studies conducted in low(er) income countries, based on case scenarios or involving less than 100 patients were excluded. REVIEW METHODS Reviewers identified studies, extracted data and assessed the quality of the evidence independently and in duplicate. The Quality Assessment of studies of Diagnostic Accuracy included in Systematic Reviews -2 checklist was used to assess risk of bias. Raw data were extracted to create 2×2 tables and calculate sensitivity and specificity. ED patient volume and casemix severity of illness were investigated as determinants of triage systems' performance. RESULTS Sixty-six eligible studies evaluated 33 different triage systems. Comparisons were restricted to the three triage systems that had at least multiple evaluations using the same reference standard (Canadian Triage and Acuity Scale, Emergency Severity Index and Manchester Triage System). Overall, validity of each triage system to identify high and low-urgency patients was moderate to good, but performance was highly variable. In a subgroup analysis, no clear association was found between ED patient volume or casemix severity of illness and triage systems' performance. CONCLUSIONS Established triage systems show a reasonable validity for the triage of patients at the ED, but performance varies considerably. Important research questions that remain are what determinants influence triage systems' performance and how the performance of existing triage systems can be improved.

Abstract
BACKGROUND In developed nations, the age of patients in emergency departments (ED) continues to increase. Many emergency triage systems, such as the Canadian Triage and Acuity Scale (CTAS), triage patients as a homogenous group, regardless of age. However, older adults have multiple comorbidities and a higher risk of undertriage. The Japan Acuity and Triage Scale (JTAS) was developed based on the CTAS and has been validated for overall adults. We assessed the validity of the JTAS for use in elderly ED patients. METHODS This was a secondary analysis of a cohort study that previously validated the JTAS in self-presenting adults of all ages in the ED of a Japanese tertiary-care hospital. We included non-transferred patients who were ≥65 years old and triaged between June 2013 and May 2014. Our primary outcome measures were overall admission and ED length of stay. Our secondary outcomes included admission to the intensive care units (ICUs) and in-hospital mortality. We examined the association between the triage level and patient outcomes with multivariable logistic regression analysis (overall and ICU admission and in-hospital mortality) and the Kruskal-Wallis rank-sum test (ED length of stay). RESULTS We included a total of 11,087 elderly patients in our study. Higher odds ratios for overall and ICU admission and in-hospital mortality corresponded to higher acuity levels. ED length of stay was significantly longer in patients with a higher JTAS level (p < 0.001). Twenty-nine percent of admissions who were triaged as lower acuity levels were related to non-acute diseases including malignancy-related events. CONCLUSION Our study suggests an association between the JTAS triage level and clinical outcomes in self-presenting elderly patients, thereby demonstrating the validity of the JTAS in these patients. However, admission due to chronic diseases including malignancy was common in patients who were rated as low acuity level.

Abstract
Background:While emergency patient triage system is effective when the pre-hospital triage acuity scale is linked with the in-hospital triage acuity scale. However, the 119 emergency medical triage system and the Korea Triage and Acuity Scale are not linked in Korea.Objective:This study aimed to investigate the correlation between the two triage systems and to utilize the results as basic data for the future development of a pre-hospital triage system.Methods:Among the 1114 patients who visited a regional emergency medical center by a 119 ambulance from April to May 2016, we analyzed the correlation between the pre-hospital and in-hospital triage systems based on the general characteristics of the patients and their reason of hospital visit (non-trauma or trauma).Results:Upon reclassifying the pre-hospital and in-hospital triage systems into three levels, among the 289 patients (28.1%) in level 3 of the pre-hospital triage, 79 (27.3%) were reclassified as the highest level (Resuscitation) in the in-hospital triage. The kappa coefficient as a measure of agreement between the two triage systems was very low at 0.211 (95% confidence interval, 0.164–0.258), and the kappa coefficient of the paramedic category was 0.232 (95% confidence interval, 0.161–0.303).Conclusion:There is a low agreement between the pre-hospital and in-hospital triage systems.

Abstract
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.

Abstract
OBJECTIVE The Japan Acuity and Triage Scale (JTAS) was developed based on Canadian Triage and Acuity Scale in 2012 and has been implemented in many Japanese EDs. We assessed the validity of JTAS by examining the association between JTAS triage levels and throughput and clinical outcomes in adult patients. METHODS We conducted a retrospective analysis of prospectively collected clinical data in the ED of a Japanese tertiary-care hospital. We included self-presenting patients who were ≥16 years of age and triaged between June 2013 and May 2014. We assessed the association between the triage level and overall admission and admission to the intensive care units (ICUs) with multivariable logistic regression analysis adjusted with patients' age and the time of visit and ED length of stay using the Kruskal-Wallis rank-sum test. We examined the predictive ability of JTAS for determining overall and ICU admission using receiver operating characteristic curves. RESULTS We included a total of 27 120 adult patients in our study. The OR for overall admission was greater with a higher triage level compared with the lowest urgency levels. ED length of stay was significantly longer with a higher JTAS level (p<0.001). The OR for ICU admission was greater in JTAS 1 (117.93 (95% CI 69.07 to 201.38)) and JTAS 2 (9.43 (95% CI 13.74 to 29.30)) compared with the lowest urgency levels. The areas under the curve for the predictive ability of JTAS for overall and ICU admission were 0.726 and 0.792, respectively. CONCLUSION Our study suggests an association of JTAS acuity with overall admission, ICU admission and ED length of stay, thereby demonstrating the predictive validity of JTAS.

Abstract
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.

Abstract
OBJECTIVE There is lack of scientific evidence regarding the effectiveness of prehospital triage systems. This study compared the two-level Taiwan Prehospital Triage System (TPTS) with the five-level Taiwan Triage and Acuity Scale (TTAS) at ED arrival regarding the prediction of patient outcomes and the utilisation of medical resources. DESIGN This was a retrospective cohort study. Adult patients transported via the emergency medical service (EMS), who arrived at the ED of a medical centre in northern Taiwan during the study period were enrolled. TTAS acuity levels 1-2 were considered comparable to the designation of 'emergent' by the prehospital TPTS system. The outcomes were analysed by comparing TPTS and TTAS by acuity levels. RESULTS Among 4430 enrolled patients, 25.2% and 74.8% were classified as emergent and non-emergent by TPTS; 44.1% and 55.9% were classified as levels 1-2 and levels 3-5 by TTAS. Of the TPTS emergent patients, 15.2% were classified as TTAS levels 3-5, whereas 30.4% of TPTS non-emergent transports were classified as TTAS levels 1-2 at the ED. TTAS levels 1-2 showed better predictability than TPTS emergent level for hospitalisation rate with a sensitivity of 70.3% (95% CI 68.3% to 72.2%) versus 41.1% (95% CI 39.0% to 43.2%), and a negative predictive value of 74.8% (95% CI 73.4% to 76.0%) versus 62.6% (95% CI 61.7% to 63.5%). CONCLUSION The current prehospital triage system is insufficient and inappropriate in classifying patients transported to the ED. The present study offers supporting evidence for the introduction of a five-level triage system to prehospital EMS systems.

Abstract
ABSTRACTObjectiveTo compare emergency department triage nurses’ time to triage and accuracy of a simulated mass casualty incident (MCI) population using a computerized version of CTAS or START systems.MethodsThis pilot study was a prospective trial using a convenience sample. A total of 20 ED triage nurses, 10 in each arm of the study, were recruited. The paper-based questionnaire contained nine simulated MCI vignettes. An expert panel arrived at consensuses on the wording of the vignettes and created a standard triage score from which to compare the study participants. Linear regression and chi-squared test were used to examine the time to triage and accuracy of triage, respectively.ResultsThe mean triage time for computerized CTAS (cCTAS) and START were 138 seconds/patient and 33 seconds/patient, respectively. The effect size due to triage method was 108 seconds/patient (95% CI 83-134 seconds/patient). The cumulative triage accuracy for the cCTAS and START tools were 70/90 (77.8%) and 65/90 (72.2%), respectively. The percent difference between cumulative triage was 6% (95% CI −19-8%).ConclusionsTriage nurses completed START triage 105 seconds/patient faster when compared to cCTAS triage and a similar level of accuracy between the two methods was achieved. However, when the typing time is taken into consideration cCTAS took 45 seconds/patient longer. The use of either CTAS or START in the ED during a MCI may be reasonable but choosing one method over another is not justified from this investigation.

Abstract
OBJECTIVES Triage is fundamental to emergency patient assessment. Effective triage systems accurately prioritize patients and help predict resource utilization. CTAS is a validated five-level triage score utilized in Emergency Departments (EDs) across Canada and internationally. Historically CTAS has been applied by triage nurses in EDs. Observational evidence suggests that the CTAS might be implemented reliably by paramedics in the prehospital setting. This is the first system-wide assessment of CTAS interrater reliability between paramedics and triage nurses during clinical practice. METHODS Variables were extracted from hospital and EMS databases. EMS providers determined CTAS on-scene, CTAS pre-transport, and CTAS on-arrival at hospital for each patient (N=14,378). The hospital arrival EMS CTAS (CTAS arrival ) score was compared to the initial nursing CTAS score (CTAS initial ) and the final nursing CTAS score (CTAS final ) incuding nursing overrides. Interrater reliability between ED CTAS initial and EMS CTAS arrival scores was assessed. Interrater reliability between ED CTAS final and EMS CTAS arrival scores, as well as proportion of patient encounters with perfect or near-perfect agreement, were evaluated. RESULTS Our primary outcome, interrater reliability [kappa=0.437 (p<0.001, 95% CI 0.421-0.452)], indicated moderate agreement. EMS CTAS arrival and ED CTAS initial scores had an exact or within one point match 84.3% of the time. The secondary interrater reliability outcome between hospital arrival EMS CTAS (CTAS arrival ) score and the final ED triage CTAS score (CTAS final ) showed moderate agreement with kappa =0.452 (p<0.001, 95% CI 0.437-0.466). CONCLUSIONS Interrater reliability of CTAS scoring between triage nurses and paramedics was moderate in this system-wide implementation study.

Abstract
Nonurgent emergency department (ED) patients are a controversial issue in the era of ED overcrowding. However, a substantial number of post-ED hospitalizations were found, which prompted for investigation and strategy management. The objective of this study is to identify risk factors for predicting the subsequent hospitalization of nonurgent emergency patients. This was a retrospective study of a database of adult nontrauma ED visits in a medical center for a period of 12 months from January 2013 to December 2013. Patient triages as either Taiwan Triage and Acuity Scale (TTAS) level 4 or 5 were considered "nonurgent." Basic demographic data, primary and secondary diagnoses, clinical parameters including blood pressure, heart rate, body temperature, and chief complaint category in TTAS were analyzed to determine if correlation exists between potential predictors and hospitalization in nonurgent patients.A total of 16,499 nonurgent patients were included for study. The overall hospitalization rate was 12.47 % (2058/16,499). In the multiple logistic regression model, patients with characteristics of males (odds ratio, OR = 1.37), age more than 65 years old (OR = 1.56), arrival by ambulance (OR = 2.40), heart rate more than 100/min (OR = 1.47), fever (OR = 2.73), and presented with skin swelling/redness (OR = 4.64) were predictors for hospitalization. The area under receiver-operator calibration curve (AUROC) for the prediction model was 0.70. Nonurgent patients might still be admitted for further care especially in male, the elderly, with more secondary diagnoses, abnormal vital signs, and presented with dermatologic complaints. Using the TTAS acuity level to identify patients for diversion away from the ED is unsafe and will lead to inappropriate refusal of care for many patients requiring hospital treatment.

Abstract
Triage classifies and prioritizes patients' care based on the acuity of the illness in emergency departments (EDs). In Taiwan, the five-level Taiwan Triage and Acuity Scale (TTAS) computerized system was implemented nationally in 2010. The purpose of this study was to understand which factors affect decision-making practices of triage nurses in the light of the implementation of the new TTAS tool and computerized system. The qualitative data were collected by in-depth interviews. Data saturation was reached with 16 participants. Content analysis was used. The results demonstrated that the factors affecting nurses' decision making in the light of the newly implemented computerized system sit within three main categories: external environmental, patients' health status, and nurses' experiences. This study suggests ensuring the patient's privacy while attending the triage desk, improving the critical thinking of triage nurses, and strengthening the public's understanding of the ED visits. These will make ED triage more efficient.

[PMID: 26861172 PMCID: PMC4748603 DOI: 10.1186/s13049-016-0208-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2015] [Accepted: 02/05/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The ratio of systolic blood pressure (SBP) to heart rate (HR), called the reverse shock index (RSI), is used to evaluate the hemodynamic stability of trauma patients. To minimize undertriage in emergency departments (EDs), we evaluated whether RSI < 1 (i.e., SBP lower than HR) could be used as an additional variable to identify patients at high risk for more severe injury within a level category of the five-level Taiwan Triage and Acuity Scales (TTAS) system. METHODS Data obtained from the Trauma Registry System, including triage level according to the TTAS system, were retrospectively reviewed for trauma admissions from January 2009 through December 2013 in a Level I trauma center. In our study, the primary outcomes were injury severity as measured using different scoring systems, including the Glasgow coma scale (GCS), abbreviated injury scale scores, and the injury severity score (ISS), and in-hospital mortality. The secondary outcomes were hospital and intensive care unit (ICU) length of stay (LOS). RESULTS Of 10,814 trauma patients, 348 patients (3.2%) had RSI < 1, whereas 10,466 (96.8%) had RSI ≥ 1. Those with RSI < 1 had greater injury severity, a higher incidence of commonly associated injuries, lower GCS scores, greater deterioration of vital signs, and a higher incidence of procedures those with RSI ≥ 1. Patients with RSI < 1 also worse outcomes including hospital and ICU LOS, a greater frequency of ICU admission, and higher in-hospital mortality. Although the five-level TTAS system provides good prioritization of patients with major trauma, using the additional criterion of RSI < 1 could identify the patients at higher risk within the same triage level (I-III). DISCUSSION The alert of a trauma patient's SBP being lower than his/her HR (RSI < 1) without the requirement of any additional equipment makes the concept of RSI particularly valuable in crowded EDs for identifying high-risk patients. RSI < 1 may serve as a principle trigger for action in the ED to alert trauma surgeons to the need for early intervention and timely preparation upon patient arrival particularly for those patients triaged in levels II and III of the TTAS system. CONCLUSIONS RSI < 1 upon arrival at an ED is an alarming sign of an associated worse outcome. Within the same triage level from level I to level III, patients with RSI < 1 had worse outcomes than those with RSI ≥ 1. The inclusion of RSI in the TTAS system may help to identify patients with more serious injuries who need an upgraded management level.

Abstract
Emergency department (ED) overcrowding threatens healthcare quality. Ambulance diversion (AD) may relieve ED overcrowding; however, diverting patients from an overcrowded ED will load neighboring EDs with more patients and may result in regional overcrowding. The purpose of this study was to evaluate the impact of different diversion strategies on the crowdedness of multiple EDs in a region. The importance of regional coordination was also explored. A queuing model for patient flow was utilized to develop a computer program for simulating AD among EDs in a region. Key parameters, including patient arrival rates, percentages of patients of different acuity levels, percentage of patients transported by ambulance, and total resources of EDs, were assigned based on real data. The crowdedness indices of each ED and the regional crowdedness index were assessed to evaluate the effectiveness of various AD strategies. Diverting patients equally to all other EDs in a region is better than diverting patients only to EDs with more resources. The effect of diverting all ambulance-transported patients is similar to that of diverting only low-acuity patients. To minimize regional crowdedness, ambulatory patients should be sent to proper EDs when AD is initiated. Based on a queuing model with parameters calibrated by real data, patient flows of EDs in a region were simulated by a computer program. From a regional point of view, randomly diverting ambulatory patients provides almost no benefit. With regards to minimizing the crowdedness of the whole region, the most promising strategy is to divert all patients equally to all other EDs that are not already crowded. This result implies that communication and coordination among regional hospitals are crucial to relieve overall crowdedness. A regional coordination center may prioritize AD strategies to optimize ED utility.

Abstract
The emergency department (ED) is a primary health care unit and one of the main entrances to the hospital system where appropriate, timely and good performance can save lives. Lack of sufficient resources, such as beds and qualified health care professionals, are major stumbling blocks to providing timely and suitable services; but resources availability and moving towards the ideal situation without attention to budget restrictions is neither practical nor achievable. In this study, simulation optimization is used to finding the best configuration in ED resources (e.g., Bed, Nurse, and GP) that affects a patient's length of stay, subject to budget constraints. Simulation is used to analyze the system and estimate target function an optimization model is then solved under different budget constraints. By considering the current budget, the new configuration of 20 inpatient beds, 3 nurses and 1 GP, with 554.4 minutes of a patient's length of stay shows 8.1% length of stay (LOS) improvement. Whilst with a maximum 35.5 budget units allocation of 20 inpatient beds, 4 nurses and 3 GPs a 9.5% decrease in LOS is proposed.

Abstract
In this review, the current status of emergency department triage in mainland China is explored, with the purpose of generating a deeper understanding of the topic. Literature was identified through electronic databases, and was included for review if published between 2002 and 2012, included significant discussion of daily emergency department triage in mainland China, was peer reviewed, and published in English or Chinese. Thematic analysis was used to identify themes which emerged from the reviewed literature. This resulted in 21 articles included for review. Four themes emerged from the review: triage process, triage training, qualification of triage nurses, and quality of triage. The review demonstrates that there is currently not a unified approach to emergency department triage in mainland China. Additionally, there are limitations in triage training for nurses and confusion around the role of triage nurses. This review highlights that emergency department triage in mainland China is still in its infancy and that more research is needed to further develop the role of triage.

Reducing uncertainty in triaging mental health presentations: examining triage decision-making. Int Emerg Nurs 2013; 22:47-51.

Abstract
Little is known about how emergency department (ED) nurses make decisions and even less is known about triage nurses' decision-making. There is compelling motivation to better understand the processes by which triage nurses make decisions, particularly with complex patient populations such as those with frequently emotive mental health and illness issues. While accuracy and reliability of triage decisions generally have been improved through the introduction of standardised triage scales and instruments, other factors such as lack of knowledge or confidence related to mental health issues, past experiences that may elicit transference and countertransference, judgments about individuals based on their behavioural presentations may impact on decisions made at triage. In this paper, we review the current research regarding the effectiveness of triage tools particularly with mental health presentations, present a theoretical framework that may guide research in understanding how triage nurses approach decision-making, and apply that framework to thinking about research in mental health-related triage. Developing a better understanding of how triage nurses make decisions, particularly in situations where issues related to mental health and illness may raise the levels of uncertainty, is crucial to ensure that they have the skills and tools they need to provide the most effective, sensitive, and compassionate care possible.

Abstract
Objectives To examine the effectiveness of a five-level Paediatric Triage and Acuity System (Ped-TTAS) by comparing the reliability of patient prioritisation and resource utilisation with the four-level Paediatric Taiwan Triage System (Ped-TTS) among non-trauma paediatric patients in the emergency department (ED). Methods The study design used was a retrospective longitudinal analysis based on medical chart review and a computer database. Except for a shorter list of complaints and some abnormal vital sign criteria modifications, the structure and triage process for applying Ped-TTAS was similar to that of the Paediatric Canadian Emergency Triage and Acuity Scale. Non-trauma paediatric patients presenting to the ED were triaged by well-trained triage nurses using the four-level Ped-TTS in 2008 and five-level Ped-TTAS in 2010. Hospitalisation rates and medical resource utilisation were analysed by acuity levels between the contrasting study groups. Results There was a significant difference in patient prioritisation between the four-level Ped-TTS and five-level Ped-TTAS. Improved differentiation was observed with the five-level Ped-TTAS in predicting hospitalisation rates and medical costs. Conclusions The five-level Ped-TTAS is better able to discriminate paediatric patients by triage acuity in the ED and is also more precise in predicting resource utilisation. The introduction of a more accurate acuity and triage system for use in paediatric emergency care should provide greater patient safety and more timely utilisation of appropriate ED resources.
