Triage assessment of transitory loss of consciousness in the emergency department-A retrospective observational study.

AIM: To establish how the Manchester Triage System can correctly prioritize patients admitted to the emergency department for transitory loss of consciousness in relation to their risk of presenting severe acute disease. DESIGN: A observational retrospective study. METHODS: A total of 2291 patients who required a triage evaluation for a transitory loss of consciousness at the emergency department of Merano Hospital between 1 January 2017 and 30 June 2019 were considered. Transitory loss of consciousness was classified according to European Society of Cardiology guidelines. The baseline characteristics of the patients were collected and divided according to the priority level assigned at triage into two different study groups: high priority (red/orange) and low priority (blue/green/yellow). The composite outcome of the study was defined as the diagnosis of a severe acute disease. RESULTS: Of the patients enrolled, 17% (390/2291) had a high-priority code and 83% (1901/2291) received a low-priority code. Overall, a severe acute disease was present in 16.9% of patients (387/2291). The Manchester Triage System had a sensitivity of 42.4%, a specificity of 88.1% and an accuracy of 80.4% for predicting severe acute disease. The discriminatory ability had an area under the receiver operating characteristic curve of 0.651 (CI 95%: 0.618-0.685). CONCLUSIONS: Despite the good specificity, the low sensitivity does not currently allow the Manchester Triage System to completely exclude patients with a severe acute disease who presented in the emergency department for a transitory loss of consciousness. Therefore, it is important to develop precise nursing tools or assessments that can improve triage performance. IMPACT: The assessment of a complex symptom can create difficulties in the stratification of patients in triage, assigning low-priority codes to patients with a severe disease. Additional tools are needed to allow the correct triage assessment of patients presenting with transitory loss of consciousness.

Electrocardiogram interpretation during nurse triage improves the performance of the triage system in patients with cardiovascular symptoms - A prospective observational study.

BACKGROUND: An immediate ECG on arrival of a patient with cardiovascular symptoms in the ED may anticipate the need for life-saving intervention. The aim was to evaluate whether ECG interpretation during nurse triage can improve triage system performance in patients with cardiovascular symptoms. METHODS: All patients who required an assessment for cardiovascular symptoms were considered for this observational study. During triage assessment, the nurses assessed the patient's level of urgency applying the MTS, then again after this evaluation (confirming or modifying the level of urgency based on personal clinical experience) and after interpretation of the patient's ECG. The main study outcome was the diagnosis of an acute cardiovascular event. RESULTS: Of the 1211 patients in the study, 10.5% presented the main study outcome. ECG interpretation in triage exhibited a nurse-physician agreement of 92.9% (p<0.001). increased patient priority in 7.5% of cases and reduced it in 39.6%. The discriminatory ability of the triage system had an area under the ROC of 0.712and 0.845 after ECG interpretation. ECG interpretation improved the baseline assessment of priority, with an NRI of 60.1% (p<0.001). CONCLUSIONS: ECG interpretation in triage can be a simple and safe tool that improves the assessment of patient priority.

Nurse triage accuracy in the evaluation of syncope according to European Society of Cardiology guidelines.

AIMS: The role of triage for patients admitted to the emergency department (ED) for a syncopal transitory loss of consciousness (TLOC) has not been debated, and no comparisons with the recent European Society of Cardiology (ESC) guidelines are currently available. To verify the ability of triage to correctly prioritize patients with syncopal TLOC. METHODS AND RESULTS: All patients who received a triage assessment at the ED of the Merano Hospital (Italy) between 1 January 2017 and 30 June 2019 for a syncope were considered. All syncope were reclassified according to the aetiology reported in the ESC guidelines. The baseline characteristics of the patients were recorded and divided according to the severity code provided during triage into two study groups: high priority (red/orange) and low priority (yellow/green/blue). The outcome of the study was the presence of a diagnosed cardiac cause within 30 days after the admission. A total of 2066 patients were enrolled (14.3% high priority vs. 85.7% low priority). Cardiac syncope was present in 7.5% of patients. Nurse triage showed a sensitivity for cardiac syncope of 44.8%, a specificity of 88.1%, and an accuracy of 84.9%. The observed discriminatory ability presented an area under the receiver operating characteristic curve of 0.685 (95% confidence interval 0.638-0.732). The possible identification of the aetiology of the syncopal TLOC by the nurse showed good agreement with the medical diagnosis (Cohen's kappa 0.857, P < 0.001). CONCLUSIONS: In cases of syncopal TLOC, nurse triage had a fair specificity but suboptimal sensitivity for cardiac causes. Specific nursing assessments following triage (e.g. precise scores or electrocardiogram) could improve the triage performance.

Effect of the Emergency Department Assessment of Chest Pain Score on the Triage Performance in Patients With Chest Pain.

The sensitivity of triage systems in identifying acute cardiovascular events in patients presented to the emergency department with chest pain is not optimal. Recently, a clinical score, the Emergency Department Assessment of Chest Pain Score (EDACS), has been proposed for a rapid assessment without additional instruments. To evaluate whether the integration of EDACS into triage evaluation of patients with chest pain can improve the triage's predictive validity for an acute cardiovascular event, a single-center prospective observational study was conducted. This study involved all patients who needed a triage admission for chest pain between January 1, 2020, and December 31, 2020. All enrolled patients first underwent a standard triage assessment and then the EDACS was calculated. The primary outcome of the study was the presence of an acute cardiovascular event. The discriminatory ability of EDACS in triage compared with standard triage assessment was evaluated by comparing the areas under the receiver operating characteristic curve, decision curve analysis, and net reclassification improvement. The study involved 1,596 patients, of that 7.3% presented the study outcome. The discriminatory ability of triage presented an area under the receiver operating characteristic curve of 0.688 that increased to 0.818 after the application of EDACS in the triage assessment. EDACS improved the baseline assessment of priority assigned in triage, with a net reclassification improvement of 33.6% (p <0.001), and the decision curve analyses demonstrated that EDACS in triage resulted in a clear net clinical benefit. In conclusion, the results of the study suggest that EDACS has a good discriminatory capacity for acute cardiovascular events and that its implementation in routine triage may improve triage performance in patients with chest pain.

Blood sampling during nurse triage reduces patient length of stay in the emergency department: A propensity score-weighted, population-based study.

BACKGROUND: Increases in patients' length of stay (LOS) in the emergency department (ED) have led to overcrowding. OBJECTIVES: In this study, the implementation of blood sampling during triage in lower priority level patients was assessed as a possible means to reduce LOS. METHODS: A retrospective study was performed from January 2018 to January 2019. Lower priority level patients who required blood sampling for further diagnosis were considered. Patients who underwent blood sampling during triage evaluation were compared with those who underwent blood sampling after a physician's initial evaluation. RESULTS: During the study period, 15,596 patients were enrolled. LOS was shorter in patients who underwent triage blood sampling, presenting a median value of 154 min in comparison with the 172 min recorded in the control group (p < 0.001). Using a propensity score-matching to control the two groups' differences, LOS remained lower in the triage-sampling group (151 vs. 175 min; p < 0.001). In the adjusted multivariate model, triage blood sampling was found to be an independent factor for a decrease in the LOS, with standardized coefficient ß = 0.857 (0.822-0.894; p < 0.001). CONCLUSIONS: Performing blood sampling during nurse triage can decrease LOS in ED and also reduce ED permanence after a physician's initial evaluation.
