Clinical Decision Making in Triage: An Integrative Review

Impact of COVID-19 pandemic on the accuracy of telephone triage of callers with shortness of breath and/or chest discomfort in Dutch out-of-hours primary care: A retrospective observational study

BACKGROUND

Anecdotal reports suggest that missed diagnosis in general practice during the first wave of the COVID-19 pandemic contributed to a drop in life-threatening events (LTEs) detected in hospitals.

OBJECTIVES

To investigate the impact of the COVID-19 pandemic on the accuracy of urgency allocation by telephone triage of patients with shortness of breath and/or chest discomfort in out-of-hours primary care (OHS-PC). Accuracy is defined as the correct allocation of high urgency to patients with LTEs and low urgency to those without.

METHODS

Retrospective observational study with data from callers contacting OHS-PC for shortness of breath and/or chest discomfort, between 1 March and 1 June 2019 (pre-pandemic) and 1 March to 1 June 2020 (first wave COVID-19 pandemic). Sensitivity and specificity of telephone urgency allocation were compared during both periods with LTEs, including acute coronary syndrome, and pulmonary embolism, as the reference.

RESULTS

3,064 adults (1,840 COVID-19 pandemic and 1,224 pre-pandemic, p < 0.001) were included in the study. The sensitivity of urgency allocation was similar during and before the COVID-19 pandemic (0.68, 95% CI 0.59 to 0.75 vs. 0.68, 95% CI 0.60 to 0.75, p = 0.944). Specificity was slightly higher during the COVID-19 pandemic (0.52, 95% CI 0.50 to 0.55 vs. 0.45, 95% CI 0.42 to 0.48, p < 0.001).

CONCLUSION

Despite a surge in calls from adults with shortness of breath and/or chest discomfort during the COVID-19 pandemic, the accuracy of telephone triage for LTEs in OHS-PC remained similar to the pre-pandemic era. Improvement of telephone triage seems necessary in both periods.

Feasibility and acceptability of a serious game to study the effects of environmental distractors on emergency room nurse triage accuracy: A pilot study

BACKGROUND

Emergency triage, which involves complex decision-making under stress and time constraints, may suffer from inaccuracies due to workplace distractions. A serious game was developed to simulate the triage process and environment. A pilot study was undertaken to collect preliminary data on the effects of distractors on emergency nurse triage accuracy.

METHOD

A 2 × 2 factorial randomized controlled trial (RCT) was designed for the study. A sample of 70 emergency room nurses was randomly assigned to three experimental groups exposed to different distractors (noise, task interruptions, and both) and one control group. Nurses had two hours to complete a series of 20 clinical vignettes, in which they had to establish a chief complaint and assign an emergency level.

RESULTS

Fifty-five nurses completed approximately 15 vignettes each during the allotted time. No intergroup differences emerged in terms of triage performance. Nurses had a very favorable appreciation of the serious game focusing on triage.

CONCLUSION

The results show that both the structure of our study and the serious game can be used to carry out a future RCT on a larger scale. The lack of a distractor effect raises questions about the frequency and intensity required to find a significant impact on triage performance.

Ensuring effectiveness and safety in emergency department triage

Triage is the first stage of a patient's journey through the emergency department and is used to determine patient acuity. There is no single quantifiable metric for determining acuity, which amalgamates different factors that are more or less relevant depending on the patient's presentation. This article explains the aim and process of triage and how nurses can ensure the process is effective and safe. The author discusses strategies nurses can use to mitigate uncertainty and to make their acuity assessments rapid, targeted and comprehensive. The author also highlights triage safety considerations, including infection prevention and control and the physical and emotional safety of patients and staff.

Accuracy of urgency allocation in patients with shortness of breath calling out-of-hours primary care: a cross-sectional study

BACKGROUND

In out-of-hours primary care (OHS-PC), semi-automatic decision support tools are often used during telephone triage. In the Netherlands, the Netherlands Triage Standard (NTS) is used. The NTS is mainly expert-based and evidence on the diagnostic accuracy of the NTS' urgency allocation against clinically relevant outcomes for patients calling with shortness of breath (SOB) is lacking.

METHODS

We included data from adults (≥18 years) who contacted two large Dutch OHS-PC centres for SOB between 1 September 2020 and 31 August 2021 and whose follow-up data about final diagnosis could be retrieved from their own general practitioner (GP). The diagnostic accuracy (sensitivity and specificity with corresponding 95% confidence intervals (CI)) of the NTS' urgency levels (high (U1/U2) versus low (U3/U4/U5) and 'final' urgency levels (including overruling of the urgency by triage nurses or supervising general practitioners (GPs)) was determined with life-threatening events (LTEs) as the reference. LTEs included, amongst others, acute coronary syndrome, pulmonary embolism, acute heart failure and severe pneumonia.

RESULTS

Out of 2012 eligible triage calls, we could include 1833 adults with SOB who called the OHS-PC, mean age 53.3 (SD 21.5) years, 55.5% female, and 16.6% showed to have had a LTE. Most often severe COVID-19 infection (6.0%), acute heart failure (2.6%), severe COPD exacerbation (2.1%) or severe pneumonia (1.9%). The NTS urgency level had a sensitivity of 0.56 (95% CI 0.50-0.61) and specificity of 0.61 (95% CI 0.58-0.63). Overruling of the NTS' urgency allocation by triage nurses and/or supervising GPs did not impact sensitivity (0.56 vs. 0.54, p = 0.458) but slightly improved specificity (0.61 vs. 0.65, p < 0.001).

CONCLUSIONS

The semi-automatic decision support tool NTS performs poorly with respect to safety (sensitivity) and efficiency (specificity) of urgency allocation in adults calling Dutch OHS-PC with SOB. There is room for improvement of telephone triage in patients calling OHS-PC with SOB.

Emergency Severity Index (ESI) algorithm in trauma patients: The impact of age during the pandemic

OBJECTIVE

The ESI algorithm is widely used to triage patients in the emergency room. However, few studies have assessed the reliability of ESI to accurately triage trauma patients. The aim of this study was to compare vital signs, resource utilization, and patient outcomes among trauma patients during the pandemic in 2020 vs. the previous year prior to the pandemic.

METHODS

This retrospective study was conducted over a 24-month period at an urban adult level one trauma center. Demographic and clinical characteristics, resource utilization, and patient outcomes were extracted from the electronic medical records and trauma registry. Trauma patients assigned ESI level 2 were stratified by age (<65 years and ≥ 65 years) and year (2019 vs. 2020) for data analysis.

RESULTS

A total of 3,788 trauma patients were included in the study. Males represented 68.4% (2,591) of patients and the median age was 50 years (IQR: 31, 69). The majority of patients were assigned ESI level 2 (2,162, 57.1%) and had a blunt mechanism of injury (3,122, 82.4%). In 2020, patients <65 years of age utilized less resources compared to 2019 (p < 0.001). Likewise, patients >65 years of age required less lab tests [OR: 0.1, 95% CI: (0.05 - 0.4)], IV fluids [OR: 0.2, 95% CI: (0.2 -0.3)], IV medications [OR: 0.6, 95% CI: (0.4 - 0.7)], and specialty consultations [OR: 0.4, 95% CI: (0.3 -0.5)] compared to 2019 (p < 0.0001). Within 2020, vital signs and resources utilized between younger and elderly patients varied significantly (p < 0.01). Correspondingly, the clinical outcomes between younger and elderly patients within 2020, differed significantly (p < 0.01).

CONCLUSIONS

The COVID-19 pandemic affected the triage of trauma patients. During 2020, patients utilized less resources compared to the previous year. Additionally, younger and elderly patients had different vital signs, resource utilization, and clinical outcomes although both being assigned ESI level 2. Younger trauma patients may have been over-triaged in 2020 due to the COVID-19 pandemic.

Strategies to improve the quality of nurse triage in emergency departments: A realist review protocol

AIM

The purpose of this realist review was to assess what works, for whom and in what context, regarding strategies that influence nurses' behaviour to improve triage quality in emergency departments (ED).

DESIGN

Realist review protocol.

METHODS

This protocol follows the PRISMA-P statement and will include any type of study on strategies to improve the triage process in the ED (using recognized and validated triage scales). The included studies were examined for scientific quality using the Mixed Methods Appraisal Tool. The framework for this realist review is based on the Behaviour Change Wheel (BCW) and the context-mechanism-outcome (CMO) models.

DISCUSSION

Nurses and ED decision makers will be informed on the evidence regarding strategies to improve the quality of triage and the factors required to maximize their effectiveness. Research gaps may also be identified to guide future research projects on the adoption of best practices in ED nursing triage.

Optimising telephone triage of patients calling for acute shortness of breath during out-of-hours primary care: protocol of a multiple methods study (Opticall)

INTRODUCTION

Callers with acute shortness of breath (SOB) are a challenge for telephone triage at out-of-hours primary care (OHS-PC) as SOB could be the sign of a potentially life-threatening disease, yet mostly is a symptom of a broad range of self-limiting disorders. Current telephone triage practice is mainly expert based and clear evidence on accuracy, safety and efficiency of the use of the Netherlands Triage Standard (NTS) by triage nurses based on the eventual clinical outcome is lacking for this domain.

METHODS AND DATA ANALYSIS

Multiple methods study in five OHS-PC services in the Utrecht region, the Netherlands. Data will be collected from OHS-PC electronic health records (EHR) and backed up tapes of telephone triage conversations, which will be linked to routine primary care EHR data. In cross-sectional studies, we will (1) validate the NTS urgency classification for adults with SOB against final diagnoses and (2) develop diagnostic prediction models for urgent diagnoses (eg, composite endpoint of urgent diagnoses, pulmonary embolism, acute coronary syndrome, acute heart failure and pneumonia). We will develop improvement measures for the use of the NTS by triage nurses through practice observations and semistructured interviews with patients, triage nurses and general practitioners (GPs). In an action research approach, we will, in collaboration with these stakeholders, implement and evaluate our findings in both GP and triage nurse educational programmes as well as in OHS-PC services.

ETHICS AND DISSEMINATION

The Medical Ethics Review Committee Utrecht, the Netherlands, approved the study protocol (protocol 21/361). We will take into account the 'code of conduct for responsible research' of the WHO, the EU General Data Protection Regulation and the 'Dutch Medical Treatment Contracts Act'. Results will be disseminated in peer-reviewed publications and at (inter)national meetings.

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.

Nurses' experiences of emergency department triage during the COVID-19 pandemic in Indonesia

PURPOSE

To explore the experiences of nurses working in emergency departments in selecting and triaging patients during the COVID-19 pandemic.

DESIGN

Descriptive phenomenology was applied in this study.

METHODS

Data were collected from nurses working at hospitals in Indonesia using snowball sampling and telephone interviews. A total of 10 emergency nurses participated, and Colaizzi's method of data analysis was applied.

FINDINGS

Six themes and 10 subthemes emerged. The main themes were "extreme challenges in triage," "feeling of responsibility under uncontrolled spread and infection," "physical and psychological exhaustion," "discovering strategies under difficult circumstances," "looking for positive reinforcement," and "optimism in togetherness." Nurses had to deal with the challenge of COVID-19 in the ED triage, interestingly so, the nurses they have shown the development of professional responsibility. Nurses are also experienced in finding patient selection and triage strategies and the sense of optimism that may influence strategy and practice during the COVID-19 pandemic.

CONCLUSIONS

This findings identify nurses' experiences in dealing with the extreme challenges of emergency department triage as well as their associated strategies and optimism.

CLINICAL RELEVANCE

Providing support to emergency nurses, improving emergency department triage, and community empowerment are suggested as strategies to improve nursing care during the COVID-19 pandemic.

Development of a Web-Based Korean Triage and Acuity Scale Learning Program for Emergency Department Nurses

The Korean Triage and Acuity Scale is a tool developed to classify severity and urgency of emergency department patients, focusing on their symptoms. Considering the importance of the Korean Triage and Acuity Scale, learning for emergency department nurses who perform the Korean Triage and Acuity Scale must be structured to ensure that the knowledge they gain can be applied to various clinical situations of the emergency department. Moreover, Web-based learning is considered appropriate in this situation. This is a methodological research study that was conducted to develop a Web-based Korean Triage and Acuity Scale learning program for emergency department nurses. The learning program was developed using each of the five phases of the "analysis, design, development, implementation, and evaluation" model, that is, analysis, design, development, implementation, and evaluation. The learning program was composed of 22 cases of emergency situations based on the Korean Triage and Acuity Scale teaching material with an approval from the Korean Triage and Acuity Scale committee in the Korean Society of Emergency Medicine. The developed program was delivered in 4-hour sessions over 4 weeks. Emergency department nurses who were given the Web-based Korean Triage and Acuity Scale learning program showed improvement in work-site transfer and reported satisfactory learning. The findings indicate that the Web-based learning program for nurses can be used as an effective tool that is easily accessible and provides multiple learning opportunities.

Patients' expectations and experiences of being involved in their own care in the emergency department: A qualitative interview study

AIMS AND OBJECTIVES

To investigate patients' experiences of being involved in their care in the emergency department (ED).

BACKGROUND

Previous research shows that when patients experience involvement during care visits, this increased their trust in the care, gave a sense of control and promoted their autonomy.

DESIGN

A qualitative descriptive design with semi-structured interviews, using the "Consolidated criteria for reporting qualitative research" (COREQ) checklist.

METHODS

Using convenience sampling, semi-structured interviews were conducted with 16 patients in the ED.

RESULTS

The study identified four categories: attention and inattention; communication and understanding; varying levels of participation; and inefficient and inaccessible care. The results show that patients expected to be treated with respect and to be involved in an open dialogue about their care. Patients' experiences of participation were related to their sense of control.

CONCLUSIONS

Based on the results of the study, the authors found that factors such as dialogue, information, attention and participation affected the patients' involvement during the ED visit. Experiences of involvement and control were linked to patients' experiences of care and of patients as individuals.

RELEVANCE TO CLINICAL PRACTICE

Healthcare providers' awareness of the importance of paying attention to the patient as an individual, and of the need for simple, continuous communication could facilitate patient involvement in own care.

Effects of environmental distractors on nurse emergency triage accuracy: a pilot study protocol

Background

The clinical decisions of emergency department triage nurses need to be of the highest accuracy. However, studies have found repeatedly that these nurses over- or underestimate the severity of patient health conditions. This has major consequences for patient safety and patient flow management. Workplace distractors such as noise and task interruptions have been pointed to as factors that might explain this inaccuracy. The use of a serious game reproducing the work environment during triage affords the opportunity to explore the impact of these distractors on nurse emergency triage accuracy, in a safe setting.

Methods/design

A pilot study with a factorial design will be carried out to test the acceptability and feasibility of a serious game developed specifically to simulate the triage process in emergency departments and to explore the primary effects of distractors on nurse emergency triage accuracy. Eighty emergency nurses will be randomized into four groups: three groups exposed to different distractors (A, noise; B, task interruptions; C, noise and task interruptions) and one control group. All nurses will have to complete 20 clinical vignettes within 2 h. For each vignette, a gold standard assessment will be determined by experts. Pre-tests will be conducted with clinicians and certified emergency nurses to evaluate the appeal of the serious game.

Discussion

Study results will inform the design of large-scale investigations and will help identify teaching, training, and research areas that require further development.

The impact of emergency department triage on the treatment outcomes of cancer patients with febrile neutropenia: A retrospective review

INTRODUCTION

The emergency department (ED) is an important entry point for patients with cancer requiring acute care due to oncological emergencies. Febrile neutropenia (FN) is one of the most common oncological emergencies and carries a significant risk of morbidity and mortality. There is evidence from previous studies that FN patients wait far longer in the ED than recommended by international guidelines.

PURPOSE

The aim was to examine whether individuals with cancer presenting at the ED with FN were triaged appropriately, and to explore if, and how, triage affected their treatment outcomes.

METHODS

A retrospective cohort design was employed to collect data over five years from all available ED records of adult cancer patients who presented with fever.

RESULTS

Of the 431 eligible patients, 63% (n = 272) were assigned triage scores that were detrimental to their immediate health. Findings from the multiple linear regression analyses showed that inaccurate or under triage was significantly associated with delayed times for the initial physician assessment, administration of antibiotics, and decision on admission. The absence of fever at the time of triage assessment contributed significantly to the prediction of under triage.

CONCLUSION

The allocation of patients with FN to a lower, inaccurate priority was partly responsible for the inability of those patients to meet the standard benchmarks for the initial physician assessment and the administration of antibiotics identified by the triage and febrile neutropenia guidelines. Ongoing strategies are needed to both enhance the application of the triage guidelines and institute organizational and system changes that promote timeliness and effectiveness throughout the entire ED episode of care.

Triage emergency nurse decision-making: Incidental findings from a focus group study

INTRODUCTION

Emergency Department (ED) triage decision-making is a complex process. Triage scales are used to determine patient acuity level, however, they do not provide information on how nurses make triage decisions. This focus group study was part of a larger project to develop a psychometrically sound instrument to measure triage decision-making by nurses; the Triage Decision-Making Instrument. We report important incidental findings that emerged during the study that the participants identified as factors impeding triage decision-making.

METHODS

Three focus groups were conducted with 11 triage Registered Nurses. They commented on the instrument items and identified factors that influence triage decision-making. Transcripts were analyzed using thematic analysis.

RESULTS

Three powerful inter-related themes emerged central to encumbering triage decision-making: competing systems (pre-hospital versus the ED), fluctuating patient volume resulting in 'intra-Canadian Triage and Acuity Scale' triaging, and personal capacity including experience and 'triage fatigue'.

DISCUSSION

The findings demonstrate how interrelated system factors impede nurses triage decision-making. Triage nurses require support in their role and initiatives are needed to reduce the pressure they feel in relation to resolving system issues. Larger system issues and the capacity of the individual decision-makers must be accounted for within the context of increasing effectiveness and safety of ED triage.

Trauma Team Activation: Accuracy of Triage When Minutes Count: A Synthesis of Literature and Performance Improvement Process

Accuracy and timeliness of trauma activations are vital to patient safety. The American College of Surgeons mandates the trauma surgeon's presence within 15 min of the patient's arrival to the emergency department (ED) 80% of the time. In 2015, at this Level II Pediatric Trauma Center, average mean activation times were approximately 16 min and activation accuracy (over- and undertriage) affected 27% of the trauma patient activations. This evidence-based quality improvement project set out to determine the most efficient method of Emergency Medical Services (EMS) intake. Communication Center (Com. Center) recordings were carefully reviewed to identify time when EMS notifies the Com. Center and actual time of trauma activation page. A timeline was formulated with assessment of time to activation and patient triage accuracy. An educational curriculum was developed as an intervention for the Com. Center staff. Education included a decision tree for trauma activations and the development of templates for our electronic health record and prompts to improve accurate activations. After additional focus groups analyzed present ED performance and the industry standard, a policy requiring only paramedic-trained staff was put in place. After implementation of the aforementioned intervention, the Com. Center performance revealed reduction in incorrect activations from 27.3% to 10.7% from 2015 to 2016. Mean activation time in January 2015 was 48.5 min before the intervention and 4.71 min postintervention in December 2016; this is a staggering reduction in activation times of 90%!

Exploring the sorting of patients in community health centres across Gauteng Province, South Africa

BACKGROUND

Primary health care worldwide faces large numbers of patients daily. Poor waiting times, low patient satisfaction and staff burnout are some problems facing such facilities. Limited research has been done on sorting patients in non-emergency settings in Africa. This research looked at community health centres (CHCs) in Gauteng Province, South Africa where queues appear to be poorly managed and patients waiting for hours. This study explores the views of clinicians in CHCs across Gauteng on sorting systems in the non-emergency ambulatory setting.

METHODS

The qualitative study design used one-to-one, in-depth interviews of purposively selected doctors. Interviews were conducted in English, with open-ended exploratory questions. Interviews were recorded, transcribed, anonymised and checked by interviewees later. Data collection and analysis stopped with information saturation. The co-author supervised and cross-checked the process. A thematic framework was developed by both authors, before final thematic coding of all transcripts was undertaken by the principal author. This analysis was based on the thematic framework approach.

RESULTS

Twelve primary health care (PHC) doctors with experience in patient sorting, from health districts across Gauteng, were interviewed. Two themes were identified, two major themes, namely Systems Implemented and Innovative Suggestions, and Factors Affecting Triage. Systems Implemented included those using vital signs, sorting by specialties, and using the Integrated Management of Childhood Illnesses approach. Systems Implemented also included doctor - nurse triage, first come first serve, eyeball triage and sorting based on main complaint. Innovative Suggestions, such as triage room treatment and investigations, telephone triage, longer clinic hours and a booking system emerged. There were three Factors Affecting Triage: Management Factor, including general management issues, equipment, documentation, infrastructure, protocol, and uniformity; and Staff Factor, including general staffing issues education and teamwork; and Patient Factor.

CONCLUSION

Developing a functional triage protocol with innovative systems for Gauteng is important. Findings from this study can guide the development of a functional triage system in the primary health care non-emergency outpatient setting of Gauteng's CHCs. The Emergency Triage, Assessment and Treatment (ETAT) tool, modified for adult and non-clinician use, could help this. However, addressing management, staff and patient factors must be integral.

A review of triage accuracy and future direction

BACKGROUND

In the emergency department, it is important to identify and prioritize who requires an urgent intervention in a short time. Triage helps recognize the urgency among patients. An accurate triage decision helps patients receive the emergency service in the most appropriate time. Various triage systems have been developed and verified to assist healthcare providers to make accurate triage decisions. The triage accuracy can represent the quality of emergency service, but there is a lack of review studies addressing this topic.

METHODS

A literature search was conducted in four electronic databases where 'emergency nursing' and 'triage accuracy' were used as keywords. Studies published from 2008 January to 2018 August were included as potential subjects. Nine studies were included in this review after the inclusion and exclusion criteria were applied.

RESULTS

Written case scenarios and retrospective review were commonly used to examine the triage accuracy. The triage accuracy from studies was in moderate level. The single-center studies which held better results than those from multi-center studies revealed the need of triage training and consistent training between emergency departments.

CONCLUSIONS

Regular refresher triage training, collaboration between emergency departments and continuous monitoring were necessary to strengthen the use of triage systems and improve nurse's triage performance.

Reliability analysis of the Manchester Triage System: inter-observer and intra-observer agreement

Objective:

To analyze the reliability of the Manchester Triage System to determine the priority of patients in emergency services.

Method:

This is a reliability study with a sample of 361 nurses. The data were collected in three stages and the questionnaires were applied using the electronic software. The agreement was measured by the evaluation of clinical cases. The outcomes evaluated were agreement with the gold standard and intra-observer in the indication of the flowchart, discriminator, and level of risk. Data were submitted to univariate and bivariate analyses. The agreement was measured by the Kappa index.

Results:

The external and internal reliability of the protocol ranged from moderate to substantial (Kappa: 0.55-0.78). The time of professional experience as a nurse, in emergency services and in the classification of risk were associated with external and internal reliability. The correct choice of the discriminator influenced the correct indication of the risk level (R² = 0.77, p <0.0001) more than the correct choice of the flowchart (R² = 0.16, p <0.0001).

Conclusion:

The reliability of the Manchester Triage System ranged from moderate to substantial and it was influenced by the clinical experience of the nurse. The protocol is safe for defining clinical priorities using different classification flowcharts.

Using the Five-Level Taiwan Triage and Acuity Scale Computerized System: Factors in Decision Making by Emergency Department Triage Nurses

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.
