Accuracy in ED Triage for Symptoms of Acute Myocardial Infarction

Impact of triage nurses' recognition of acute coronary syndrome on patients' clinical outcomes: A retrospective study

BACKGROUND

Triage nurses' pivotal role in initial assessment makes their competence crucial. However, the specific impact on Acute Coronary Syndrome (ACS) recognition and outcomes remains unclear in Jordanian healthcare. Understanding this relationship could enhance ACS management and patient outcomes in Jordanian Emergency Departments (EDs).

OBJECTIVE

To assess how triage nurses' recognition of ACS diagnosis affects patient outcomes in Jordan.

METHODS

This retrospective study examined records of 150 ACS patients admitted to the coronary care unit (CCU). Data extraction assessed triage nurses' accuracy in recognizing ACS symptoms and the timelines for diagnosis procedures (e.g., electrocardiogram [ECG]) and treatment provision (e.g., thrombolytic) based on triage decisions. It also evaluated the impact on treatment outcomes, including length of stay in the ED and hospital. Multiple linear regression analyses quantified the influence of under-triage on treatment outcomes.

RESULTS

The sample comprised 150 patients. Most were female (78.7%), aged 45-59.9 years (37.3%). ACS classifications: unstable angina (52.0%), STEMI (38.0%), NSTEMI (10.0%). The study included a cohort of ACS patients, with findings indicating varying degrees of under-triage by triage nurses. Analysis of timelines revealed significant delays in diagnosis and treatment initiation for patients subjected to under-triage. Multiple linear regression analyses demonstrated a robust association between under-triage and prolonged time to essential treatment outcomes, including delays in physician assessment, ECG performance, thrombolytic administration, and extended ED length of stay.

CONCLUSION

Triage nurses' knowledge and competency are crucial determinants of accurate ACS recognition and subsequent clinical outcomes for patients presenting to the ED in Jordan. Investing in ongoing education and training programs for triage nurses may lead to improved ACS recognition rates and better patient outcomes in Jordanian healthcare settings.

A Nationwide Study of Emergency Nurses' Triage Decisions for Potential Acute Coronary Syndrome

INTRODUCTION

This study aimed to identify the symptoms used to assess angina, determine how emergency nurses make triage decisions for potential acute coronary syndrome, and determine emergency nurses' initial actions.

METHODS

This was a cross-sectional, survey-based design. Emergency nurses were recruited through a posting on the Emergency Nurses Association website and through postcards. Measures included demographic data, assessment of angina, and the Nurses' Cardiac Triage Instrument. Data were analyzed using descriptive statistics and ordinal logistic regression.

RESULTS

A total of 414 registered nurses with a mean age of 41.7 (SD = 12.0) years participated. They were predominantly female (80.7%), had a baccalaureate degree (60.1%), and worked as a registered nurse for a median 10.0 years. Common terms used to assess angina were chest pain (79.5%), chest pressure (77.3%), chest tightness (72.9%), and chest discomfort (72.5%). The severity of chest pressure (median 5.0, interquartile range 1.0) and nature of chest pain (median 5.0, interquartile range 1.0) had the highest overall median scores to support initial cardiac triage decisions. Associated symptoms of diaphoresis, fatigue, and shortness of breath along with health history contributed to decision making.

DISCUSSION

Emergency nurses primarily used chest symptoms and health history when deciding to evaluate for acute coronary syndrome in the emergency department. Associated symptoms of diaphoresis, fatigue, and shortness of breath, along with health history, also contributed to decision making. Initial registered nurse actions were to obtain an electrocardiogram, prepare the patient for the cardiac catheterization laboratory, and notify the emergency physician of the patient's admission.

Comparing Emergency Nursing Measures Before and During COVID-19: A Retrospective Study of Assessment, Triage, and Workflow

Background

The COVID-19 pandemic significantly impacted emergency department (ED) operations and patient care. Understanding its effects on nursing processes, triage accuracy, and wait times is pivotal for optimizing outcomes.

Objectives

This study aimed to analyze the differences in nursing processes, triage accuracy, and wait times before and during the COVID-19 pandemic.

Design

A retrospective cohort study.

Methods

The study analyzed 224 electronic medical records from a single ED, with 120 records from the pre-pandemic period (January 2019-February 2020) and 104 records from the pandemic period (March 2020-March 2021). Dependent variables included missed nursing care per validated scales, triage accuracy per Emergency Severity Index, and wait times for nursing triage and physician examination. Independent factors encompassed sociodemographic, clinical characteristics, and organization dynamics.

Results

Sociodemographic and clinical profiles were comparable between periods. Triage accuracy remained high except for older patients. Nursing triage wait times differed little, yet physician examination and urgent case waits decreased amidst the pandemic. Nursing documentation completeness, such as recording patient status and mental state, augmented during this crisis period.

Conclusion

This evaluation identified differences in triage accuracy, wait times, and documentation completeness before and during the COVID-19 pandemic period at a single institution. Patient age and clinical status influenced some metrics. Lessons from comparing precrisis benchmarks to intra-pandemic nursing performance may guide pandemic preparedness strategies. Further research is warranted to optimize emergency processes and outcomes during public health emergencies, as well as examine strategies through multicenter investigations comparing prepandemic to intra-pandemic performance to provide broader insights into challenges and inform efforts to bolster emergency care through future crises.

Triage Accuracy of Emergency Nurses: An Evidence-Based Review

INTRODUCTION

Accurate triage assessment by emergency nurses is essential for prioritizing patient care and providing appropriate treatment. Undertriage and overtriage remain an ongoing issue in care of patients who present to the emergency department. The purpose of this literature review was to examine factors associated with triage accuracy in the emergency department.

METHODS

We conducted an evidence-based literature review using the Cumulative Index to Nursing and Allied Health Literature, PubMed, and Embase. The search focused on peer-reviewed articles in English, available in full text, published between January 2011 and December 2021.

RESULTS

A total of 14 articles met inclusion criteria and revealed the following 3 themes for triage accuracy: triage nurse characteristics, patient characteristics, and work environment. Triage nurses' accuracy rates ranged from 59.3% to 82%, with experience in triage associated with higher accuracy. Patient characteristics influenced triage accuracy, with nontrauma patients being undertriaged and trauma patients often overtriaged. The work environment played a role, as accuracy rates varied based on shift time and patient volume. Competing systems between prehospital and ED triage posed challenges and affected accuracy during fluctuations in patient volumes.

DISCUSSION

This review underscores the complex nature of ED triage accuracy. It highlights the importance of nurse experience, training programs, patient characteristics, and the work environment in enhancing triage decision making. Enhanced understanding of these factors can inform strategies to optimize triage accuracy and improve patient outcomes.

Factors related to under-triage of patients with acute coronary syndrome in the emergency department: A retrospective study

INTRODUCTION

This study aimed to provide fundamental data to avoid under-triage in the initial severity classification of patients with suspected acute coronary syndrome (ACS) by analyzing factors associated with patients who visited the emergency department (ED).

METHODS

This retrospective study identified factors related to under-triage by comparing the characteristics of participants diagnosed with ACS and appropriately classified those who were under-triaged.

RESULTS

The probability of under-triage increased 5.402 times in patients who visited the ED immediately than in those who visited the ED through an outpatient clinic. The probability of under-triage decreased in patients who visited the ED by ambulance rather than using their personal vehicle. Furthermore, when patients experienced chest pain, the tendency for under-triage decreased. The under-triage tendency increased 8.315 times in patients with dementia.

CONCLUSIONS

Medical staff training on the classification of non-specific symptoms accompanying diseases is needed. Patients with ACS need to be aware of the symptoms that require visiting the ED and the appropriate route and method. Therefore, it is possible to avoid under-triage for possible ACS during the initial triage, and triage can be performed quickly and accurately.

Effect of triage training on nurses' practice and triage outcomes of patients with acute coronary syndrome

BACKGROUND

Accurate assessment and prompt management of patients with acute coronary syndrome (ACS) is a complex process for emergency department (ED) nurses and has variable clinical outcomes. The aim of the present study was to determine the effectiveness of an educational intervention on nurses' practice during the triage of patients with ACS and the triage outcomes in this group of patients.

METHODS

In this quasi-experimental study, a pretest-posttest group of 24 nurses were included by convenience sampling method and 960 patients with ACS were selected by sequential sampling during the pre-intervention (n = 480) and post-intervention (n = 480) phases. A case-based learning (CBL) intervention was performed for nurses for one month considering the role of the triage nurse according to the American College of Cardiology (ACC) and the American Heart Association (AHA) recommendations as well as the factors affecting the proper identification and management of patients with ACS. During patient triage in the pre- and post-intervention phases, the "Triage Nurse Practice Checklist" and the "Medical Electronic Records" were used to assess nurses' practice and the triage outcomes in patients, respectively.

RESULTS

The overall mean score of the triage nurses' practice and its subscales, including Primary monitoring and assessment, cardiovascular risk factors assessment, evaluation of coronary heart disease (CHD) symptoms, chest pain management, and adherence to the ACC/AHA practice guidelines were significantly improved in the post-intervention phase compared with the pre-intervention phase (p < 0.001). There was no significant difference between the triage outcomes, including in-hospital mortality within 24 hours, death in ED, hospitalization in other wards, and discharge from ED in the pre and post-intervention phases (P = 0.723).

CONCLUSION

The development of a cardiac triage-specific educational program could improve the performance of nurses in the evaluation and management of patients with ACS, but had no effect on the triage outcomes in this group of patients. We recommend a quality improvement project or a critical outcomes-based triage system to assess ACS patients' care needs in the ED.

Triage Errors in Primary and Pre-Primary Care

Triage errors are a major concern in health care due to resulting harmful delays in treatments or inappropriate allocation of resources. With the increasing popularity of digital symptom checkers in pre–primary care settings, and amid claims that artificial intelligence outperforms doctors, the accuracy of triage by digital symptom checkers is ever more scrutinized. This paper examines the context and challenges of triage in primary care, pre–primary care, and emergency care, as well as reviews existing evidence on the prevalence of triage errors in all three settings. Implications for development, research, and practice are highlighted, and recommendations are made on how digital symptom checkers should be best positioned.

Implementing a new emergency medical triage tool in one health region in Norway: some lessons learned

BACKGROUND

Acutely sick or injured patients depend on ambulance and emergency department personnel performing an accurate initial assessment and prioritisation (triage) to effectively identify patients in need of immediate treatment. Triage also ensures that each patient receives fair initial assessment. To improve the patient safety, quality of care, and communication about a patient's medical condition, we implemented a new triage tool (the South African Triage Scale Norway (SATS-N) in all the ambulance services and emergency departments in one health region in Norway. This article describes the lessons we learnt during this implementation process.

METHODS

The main framework in this quality improvement (QI) work was the plan-do-study-act cycle. Additional process sources were 'The Institute for Healthcare Improvement Model for improvement' and the Norwegian Patient Safety Programme.

RESULTS

Based on the QI process as a whole, we defined subjects influencing this work to be successful, such as identifying areas for improvement, establishing multidisciplinary teams, coaching, implementing measurements and securing sustainability. After these subjects were connected to the relevant challenges and desired effects, we described the lessons we learnt during this comprehensive QI process.

CONCLUSION

We learnt the importance of following a structured framework for QI process during the implementation of the SATS-N triage tool. Furthermore, securing anchoring at all levels, from the managements to the medical professionals in direct patient-orientated work, was relevant important. Moreover, establishing multidisciplinary teams with ambulance personnel, emergency department nurses and doctors with various medical specialties provided ownership to the participants. Meanwhile, coaching provided necessary security for the staff directly involved in caring for patients. Keeping the spirit and perseverance high were important factors in completing the implementation. Establishment of the regional network group was found to be important for sustainability and further improvements.

First Nations status and emergency department triage scores in Alberta: a retrospective cohort study

BACKGROUND

Previous studies have found that race is associated with emergency department triage scores, raising concerns about potential health care inequity. As part of a project on quality of care for First Nations people in Alberta, we sought to understand the relation between First Nations status and triage scores.

METHODS

We conducted a population-based retrospective cohort study of health administrative data from April 2012 to March 2017 to evaluate acuity of triage scores, categorized as a binary outcome of higher or lower acuity score. We developed multivariable multilevel logistic mixed-effects regression models using the levels of emergency department visit, patient (for patients with multiple visits) and facility. We further evaluated the triage of visits related to 5 disease categories and 5 specific diagnoses to better compare triage outcomes of First Nations and non-First Nations patients.

RESULTS

First Nations status was associated with lower odds of receiving higher acuity triage scores (odds ratio [OR] 0.93, 95% confidence interval [CI] 0.92-0.94) compared with non-First Nations patients in adjusted models. First Nations patients had lower odds of acute triage for all 5 disease categories and for 3 of 5 diagnoses, including long bone fractures (OR 0.82, 95% CI 0.76-0.88), acute upper respiratory infection (OR 0.90, 95% CI 0.84-0.98) and anxiety disorder (OR 0.67, 95% CI 0.60-0.74).

INTERPRETATION

First Nations status was associated with lower odds of higher acuity triage scores across a number of conditions and diagnoses. This may reflect systemic racism, stereotyping and potentially other factors that affected triage assessments.

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.

Factors affecting triage accuracy in patients with a definitive diagnosis of acute myocardial infarction

BACKGROUND

Triage is important to identifying patients with patients acute myocardial infartction (AMI) patients' triage accuracy, this research aims to study it in the ED, regarding factors affecting it.

METHODS

This retrospective study analyzed data from patients with an ultimate diagnosis of AMI who had been admitted to the ED of Imam Hossein Hospital in Shahroud, Iran, over the last three years and had met the study criteria. Data were collected from the hospital archives.

RESULTS

The triage accuracy was 82 % for a total of 400 patients with an ultimate diagnosis of AMI. Men, smokers, and those who had complained about chest pain and sweating at the time of their admission, as well as patients who had used pre-hospital medical services, had higher triage accuracy; indigestion or burning sensation had led to under triage. Based on multiple regression analysis, gender, chest pain, and sweating were found to be significant predictors of triage accuracy. Accordingly, male patients and those with chest pain and sweating had higher triage accuracy.

CONCLUSIONS

Despite the increase in triage accuracy rate in this study compared to previous studies, under triage continues to be a problem in the triage of patients with an ultimate diagnosis of AMI.

Exploring the complex interactions of baseline patient factors to improve nursing triage of acute coronary syndrome

Emergency department (ED) nurses need to identify patients with potential acute coronary syndrome (ACS) rapidly because treatment delay could impact patient outcomes. Aims of this secondary analysis were to identify key patient factors that could be available at initial ED nurse triage that predict ACS. Consecutive patients with chest pain who called 9-1-1, received a 12-lead electrocardiogram in the prehospital setting, and were transported via emergency medical service were included in the study. A total of 750 patients were recruited. The sample had an average age of 59 years old, was 57% male, and 40% Black. One hundred and fifteen patients were diagnosed with ACS. Older age, non-Caucasian race, and faster respiratory rate were independent predictors of ACS. There was an interaction between heart rate by Type II diabetes receiving insulin in the context of ACS. Type II diabetics requiring insulin for better glycemic control manifested a faster heart rate. By identifying patient factors at ED nurse triage that could be predictive of ACS, accuracy rates of triage may improve, thus impacting patient outcomes.

The Association Between Patient Outcomes and the Initial Emergency Severity Index Triage Score in Patients With Suspected Acute Coronary Syndrome

BACKGROUND

The Emergency Severity Index (ESI) is a widely used tool to triage patients in emergency departments. The ESI tool is used to assess all complaints and has significant limitation for accurately triaging patients with suspected acute coronary syndrome (ACS).

OBJECTIVE

We evaluated the accuracy of ESI in predicting serious outcomes in suspected ACS and aimed to assess the incremental reclassification performance if ESI is supplemented with a clinically validated tool used to risk-stratify suspected ACS.

METHODS

We used existing data from an observational cohort study of patients with chest pain. We extracted ESI scores documented by triage nurses during routine medical care. Two independent reviewers adjudicated the primary outcome, incidence of 30-day major adverse cardiac events. We compared ESI with the well-established modified HEAR/T (patient History, Electrocardiogram, Age, Risk factors, but without Troponin) score.

RESULTS

Our sample included 750 patients (age, 59 ± 17 years; 43% female; 40% black). A total of 145 patients (19%) experienced major adverse cardiac event. The area under the receiver operating characteristic curve for ESI score for predicting major adverse cardiac event was 0.656, compared with 0.796 for the modified HEAR/T score. Using the modified HEAR/T score, 181 of the 391 false positives (46%) and 16 of the 19 false negatives (84%) assigned by ESI could be reclassified correctly.

CONCLUSION

The ESI score is poorly associated with serious outcomes in patients with suspected ACS. Supplementing the ESI tool with input from other validated clinical tools can greatly improve the accuracy of triage in patients with suspected ACS.

Comparison between Emergency Severity Index and Heart Failure Triage Scale in heart failure patients: A randomized clinical trial

BACKGROUND

It is not clear whether Emergency Severity Index (ESI) is valid to triage heart failure (HF) patients and if HF patients benefit more from a customized triage scale or not. The aim of study is to compare the effect of Heart Failure Triage Scale (HFTS) and ESI on mistriage among patients with HF who present to the emergency department (ED).

METHODS

A randomized clinical trial was conducted from April to June 2017. HF patients with dyspnea were randomly assigned to HFTS or ESI groups. Triage level, used resources and time to electrocardiogram (ECG) were compared between both groups among HF patients who were admitted to coronary care unit (CCU), cardiac unit (CU) and discharged patients from the ED. Content validity was examined using Kappa designating agreement on relevance (K*). Reliability of both scale was evaluated using inter-observer agreement (Kappa).

RESULTS

Seventy-three and 74 HF patients were assigned to HFTS and ESI groups respectively. Time to ECG in HFTS group was significantly shorter than that of ESI group (2.05 vs. 16.82 minutes). Triage level between HFTS and ESI groups was significantly different among patients admitted to CCU (1.0 vs. 2.8), cardiac unit (2.26 vs. 3.06) and discharged patients from the ED (3.53 vs. 2.86). Used resources in HFTS group was significantly different among triage levels (H=25.89; df=3; P<0.001).

CONCLUSION

HFTS is associated with less mistriage than ESI for triaging HF patients. It is recommended to make use of HFTS to triage HF patients in the ED.

Improving STEMI management in the emergency department: Examining the role of minority groups and sociodemographic characteristics

OBJECTIVE

To evaluate whether a fast-track intervention program will reduce time-lags of patients with STEMI considering minority groups, various socioeconomic status (SES) and clinical risk factors.

METHODS

A retrospective-archive study was conducted according to clinical guidelines, comparing all STEMI patients (n = 140) admitted to the emergency department (ED) before (n = 60) and during (n = 80) implementation of the fast track intervention program. The program comprised four steps: (1) immediate bed rest, (2) marking patient chart, (3) assessing time-lags according to defined clinical guidelines, and (4) physician signing a dedicated sticker on the ECG.

RESULTS

The major ethnic group compared to other minority patients with STEMI were less delayed for physician examination (r = -0.398, p < 0.01), spent less time at ED (r = -0.541, p < 0.01) and reached percutaneous coronary intervention earlier (r = -0.672, p < 0.01). Patients with higher SES spent less time for physician (r = -338, p < 0.05) and in the ED (r = -0.415, p < 0.01). Before intervention patients with diabetes mellitus (DM) spent more time at ED compared to non DM patients, however during intervention this difference was blurred (β = -0.803, p < 0.001). Gaps regarding sociodemographic bias remained present throughout the intervention despite monthly staff evaluations considering patient cases.

CONCLUSIONS

The fast track intervention was associated with less time at ED and to cardiac reperfusion. Yet, sociodemographic bias was present. Our findings highlight the need for the healthcare profession to address the role of biases in disparities in healthcare.

Towards prompt electrocardiogram acquisition in triage: Preliminary testing of a symptom-based clinical prediction rule for the Android tablet

BACKGROUND

For patients with suspected acute coronary syndrome, international guidelines indicate that an Electrocardiogram (ECG) should be performed within 10 min of first medical contact, however success at achieving these guidelines is limited.

AIMS

The purpose of this study was to develop and perform initial testing of a clinical prediction rule embedded in a tablet application, and to expedite the identification of patients who require an electrocardiogram within 10 min.

METHODS

This derivation of the Acute Coronary Syndrome Application (AcSAP) comprised of three local studies, an unpublished audit and literature critique. The AcSAP was prospectively tested over four months in patients presenting to the Emergency Department (ED) of a Dublin teaching hospital. An audit form retrieved data pertaining to times of: registration to the emergency department, triage, first electrocardiogram and diagnosis. The AcSAP was subsequently evaluated by experienced triage nurses ( n=18) who had utilised it.

RESULTS

The AcSAP was activated 379 times. Patients with ST Elevation Myocardial Infarction (STEMI) and non-ST Elevation Myocardial Infarction (NSTEMI) were significantly more likely to return a categorisation of 'immediate ECG' or 'ECG within 10 min' ( p<0.001). There was a significant difference in 'triage to ECG' times across categories, the 'immediate ECG' categorisation resulting in the shortest time ( p=0.002). Evaluations suggest that staff found the tool quick and easy to use and results seemed accurate.

CONCLUSION

Testing of the AcSAP suggests that it accurately identifies patients who require an ECG within 10 min. As such, it has the potential to support the meeting of clinical guidelines for ECG acquisition.

Development and preliminary testing of an online software system to facilitate assessment of accuracy and consistency in applying the Australasian Triage Scale

PURPOSE

The aim of this project was to design and evaluate an online software system to facilitate the assessment of triage decision accuracy and consistency in applying the Australasian Triage Scale.

BACKGROUND

Triage is a critical component of emergency nursing practice, which affects patient access to emergency care. Accurate and consistent triage decisions are vital to ensuring patient safety, timely access to care and ED operation. Presently, there is no standard process to examine triage decisions, measure current performance and support department and individual performance development activities to improve patient safety and quality of emergency care.

METHOD

An iterative design guided by a human factors development approach was used to develop a retrospective, focus-based analysis system to evaluate triage decision accuracy and consistency, and enable the exploration of service gaps and opportunities for practice change and professional development.

RESULTS

Triage decision accuracy and consistency, including areas for improvement are detectable and quantifiable. Findings generated may aid in departmental performance and professional development of triage nurses.

CONCLUSION

This is the first system developed to assess decision accuracy and consistency in applying the Australasian Triage Scale. This paper has described the development and preliminary testing of a user-centred design process and implementation of a web-based system to evaluate triage decision accuracy and consistency.
