Factors that influence care priority for chest pain patients using the manchester triage system

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.

Mortality risk for different presenting complaints amongst older patients assessed with the Manchester triage system

PURPOSE

Older people often present to the Emergency Department with nonspecific complaints. We aimed (1) to examine characteristics of older patients presenting to the ED triaged with the presentational flowchart 'unwell adult' of the Manchester triage system (MTS) and (2) to assess the different mortality and admission rates among triage categories.

METHODS

Retrospective cohort study including all consecutive patients aged 70 years and older who visited the ED of a tertiary care hospital in the Netherlands during a 1-year period. The primary outcome was 30-day mortality. Secondary outcomes were 7-day mortality, hospital admission and ED length of stay.

RESULTS

4255 patients were included in this study. Mean age was 78 years (IQR 73.9-83.4) and 2098 were male (49.3%). The MTS presentational flowchart 'unwell adult' was the most commonly used flowchart (n = 815, 19.3%). After the infrequent flowchart 'major trauma' (n = 9, 13.8%), 'unwell adult' had the highest 30-day mortality (n = 88, 10.8%). When compared to all other flowcharts, patients assigned as 'unwell adult' have significantly higher 30-day mortality rates (OR 1.89 (95%CI 1.46-2.46), p =  < 0.001), also when adjusted for age, gender and triage priority (OR 1.75 (95%CI 1.32-2.31), p =  < 0.001). Patients from the 'unwell adult' flowchart had the highest hospital admission rate (n = 540, 66.3%), and had among the longest ED length of stay.

CONCLUSIONS

Older ED patients are most commonly assigned the presentational flowchart 'unwell adult' when using the MTS. Patients in this category have the highest non-trauma mortality and highest hospital admission rates when compared to other presenting complaints.

Chest Pain Severity Rating Is a Poor Predictive Tool in the Diagnosis of ST-Segment Elevation Myocardial Infarction

Current ST-segment elevation myocardial infarction (STEMI) guidelines require persistent electrocardiogram ST-segment elevation, cardiac enzyme changes, and symptoms of myocardial ischemia. Chest pain is the determinant symptom, often measured using an 11-point scale (0-10). Greater severity of chest pain is presumed to be associated with a stronger likelihood of a true positive STEMI diagnosis. This retrospective observational cohort study considered consecutive STEMI patients from May 02, 2009 to December 31, 2018. Analysis of standard STEMI metrics included positive electrocardiogram-to-device and first medical contact-to-device times, presence of comorbidities, false-positive diagnosis, 30-day and 1-year mortality, and 30-day readmission. Chest pain severity was assessed upon admission to the primary percutaneous coronary intervention hospital. We analyzed 1409 STEMI activations (69% male, 66.3 years old ± 13.7 years). Of these, 251 (17.8%) had no obstructive lesion, consistent with false-positive STEMI. Four hundred sixty-six (33.1%) reported chest pain rating of 0 on admission, 378 (26.8%) reported mild pain (1-3), 300 (21.3%) moderate (4-6), and 265 (18.8%) severe (7-10). Patients presenting without chest pain had a significantly higher rate of false-positive STEMI diagnosis. Increasing chest pain severity was associated with decreased time from first medical contact to device, and decreased in-hospital, 30-day and 1-year mortality. Severity of chest pain on admission did not correlate to the likelihood of a true-positive STEMI diagnosis, although it was associated with improved patient prognosis, in the form of improved outcomes, and shorter times to reperfusion.

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.
