Abstract

Background: Coronary vascular disease (CVD) is the premier cause of fatality in the world. In Pakistan, 30 to 40% of all deaths occur due to CVD. The emergency department triage is carried out to prioritize the care of critical patients. Errors during triage may lead to mortality and morbidity of the patient. The current study's objective is to determine the triage process of acute myocardial infarction patients and its associated accuracy and delays during the acute myocardial infarction process of care in the emergency department.


Methods: In this descriptive study, data were collected retrospectively from Shifa International Hospital. The consent was taken from participating Registered nurses (RNs) who were involved in the triage process. Nurses with experience of less than 1 year in the emergency department were not part of the study, while only those patients with symptoms indicative of Acute Myocardial Infarction and age of 21 years or older were included in the current study. EMR system was used on a daily basis as a method to capture data for the study. The actual clock time in minutes from arrival until triage and obtain ECG as greater than 10 minutes was identified as a delay.


Results: The 8 R.N. participated in the current study with a mean age and experience of 28.11 years and 4.77 years. The patients' age was 22-74 years, which consist of 58.9% male and 41.1% female. Out of 224 patients, 20.53% of patients were smokers, 39.3% were diabetic, 44.6% were CVD, and 78.5% were reported for chest pain. Delay care such as the mean triage and ECG time recorded was 6.75, and 7.30 min, the mean E.R. physician and Cardiology resident assessment was 11 min and 25.19 min, respectively, which were significantly found according to the recommended guidelines of AHA. The triage accuracy in the current study was recorded as 80.35%.


Conclusion: In Pakistan, no proper triage system is developed, and no time limits and guidelines are defined for the completion of the triage process. In the current study, the triage level designations, ECG delay, E.R. and cardiology resident assessment delay were found insignificant, and triage designation was found inaccurate with 19.6% of patients, which lead to delay the re-perfusion therapy. In patients with AMI symptoms, triage accuracy and quick ECG helps E.R. physician assessment to take a quick better decision for cardiac care. It helps patients to get re-perfusion therapy on time for acute myocardial infarction.

Introduction

In Pakistan's population, coronary vascular diseases become the premier risk; due to this disease, 30- 40% of all deaths occur in Pakistan. Every year the death caused by cardiac disease is extended to 200,000 per year 1 , 2 . Annually, more than 7.6 million patients were admitted to Emergency Departments in the U.S., with chest pain's main complaint 3 . It was reported that 31% of all deaths occur due to cardiovascular disease, with 80% happening in low- and middle-income countries 4 . In the Emergency Department, the accurate and timely triage level designation plays a key role in lessening death and disease. Still, facts show that accuracy rates are low, which delays the care process of a patient. In the American Heart Association (AHA) national guidelines, it is mentioned that health care providers need to fulfill cardiac emergency care goals from point of entry in emergency department to 90 minutes 5 . In acute myocardial infarction, electrocardiograms obtain, and doctors are evaluated within 10 minutes, and start thrombolytic medications within a half hour (labeled as door-to-needle or fibrinolysis) or provide percutaneous coronary intervention (labeled as door-to-balloon) within one and half hour 6 . To restore blood flow in the heart, rapid assessment and treatment are vital for the heart to preserve cardiac function. First of all, the nursing triage is done in the emergency department, which directly affects initial interventions and care as their skills to identify the Acute Myocardial Infarction play a vital role in taking rapid action. After the first occlusion, the Cardiac cell death can happen within twenty minutes or up to two hours 7 , 8 .

The struggle to handle most patients coming for healthcare is done by the Management of Emergency, physician, and R.N.s 9 . The Emergency Triage Nurse's main role is to define the severity of disease and urgency of care required, such as in cardiac emergency patients, who require rapid care in triage. However, triage requires certain diagnostic tests to aid decisions. The subjective decision of triage level designation depends upon the collected data, observations, brief assessment of nursing, medical history, patient symptoms, and occasionally family history 10 , 11 . In Pakistan, no proper triage system is developed, and no time limits and guidelines are defined for the completion of the triage process. The patient's assessment and a triage level designation is the triage goal representing symptoms urgency 12 . The Emergency Department can use ESI tool for accurate triage level to aid early interventions and affect patient outcomes. In Pakistan, the Triage system was introduced a few years ago in some hospitals. The triage process's standard guidelines are not available in Pakistan however, few hospitals in Pakistan have implemented a three or five-level triage system 13 , 14 . This study will conclude the effectiveness of five-level ESI in a patient with acute myocardial infarction patient in the Emergency Department.

Methodology

Research Design

This was a cross-sectional study in which prospective data for R.N. triage process in the Emergency Department was utilized. The data was collected through R.N. of patients involved directly in the triage process to determine the delay in care and accuracy of the designation of R.N. triage level. The data was collected from patients with symptoms suggestive of acute myocardial infarction by using EMR system of E.D. department daily. Data was collected by using hospital medical record file of patients such as the (a) characteristics of patients (age, race/ethnicity, gender, past medical history and presentation of symptom), characteristics of R.N. (age, level of education, years of experience in Nursing and Emergency department), and (b) delay in ECG obtainment, E.R. physician assessment, cardiology resident assessment and designation of triage level accuracy given by R.N. in the triage of Emergency Department. The study dependent variables were the designation of triage level accuracy, time to initial triage assessment, time to gain an Electrocardiogram, time to E.R. physician assessment, and time to cardiology resident.

In this research study, the patients admitted to the emergency department with a complaint of pain in the chest, indicative symptoms of acute myocardial infarction were included to produce the required data required. Shifa International Hospital, located in Islamabad, Pakistan, with more than 400 beds, was the designated site to conduct the study. With one year in nursing, the nurses who understand the ESI triage process and are involved in the current study were included in the triage process.

To select a sample from the population for study, the inclusion criteria were patients presenting with symptoms indicative of Acute Myocardial Infarction. The age of the patient must be 21 years old and older. Data were collected for two months of the patient who were presented in the emergency department of tertiary care hospital.

Data collections

The EMR system was used daily as a method to capture data for the study. The patient files were retrieved by requesting to the medical record department. The collected data was reviewed to fill data collecting form as well as patient demographics. A patient EMR sample was utilized by following inclusion and exclusion criteria to get Emergency Department variables related to triage. The presenting complaints were chest discomfort or chest pain, diaphoresis, nausea, palpitation, shortness of breath, syncope, vomiting, or weakness suggestive of Acute Myocardial Infarction symptoms. The actual clock time from arrival to triage and ECG results are then identified as a delay if greater than 10 minutes. The additional likely points or delay was arrival time for evaluation of E.R. physician greater than 10 min, and cardiology resident arrival time for assessment greater than 30 min was also collected.

Triage process

The designation of triage level 2 must have been given to patients presenting with symptoms indicative of acute myocardial infarction (AMI). The designation of the level of triage was coded as inaccurate for this study if it was not given. The dichotomously dependent variables were coded as yes for accurate and no for inaccurate.

Analysis of Data

The frequencies of the categorical variables were calculated through Descriptive statistics. The continuous variables descriptive were calculated to conclude that (1) if values are missing, and (2) the data distribution. The Statistical Package for the Social Sciences (SPSS; Version 22.0) software was utilized for all data analysis.

Results

Table 1 Years of experience of Registered nurses in Emergency department

There were 12 nurses recognized among 70 nurses working in the emergency department by following the inclusion criteria of the study. Only 8 R.N. were given consent to participate, contributed to a 67% response rate, consisting of 2 females and 6 males, as shown in Figure 1 . The age range was 24 – 33 years of nurses with a mean age was 28.11 years (SD = ± 2.31), and experience as R.N. was 2-7 years with mean 4.77 years (SD = ± 1.20) in the Emergency department ( Table 1 ). Most of the nurses had diplomas (75%), while the remaining 25% hold a bachelor's degree in nursing. Total 224 patients were detected with an age range of 22 - 74 years, which constitute 59% male and 41% female ( Table 2 , Table 3 ).

Among all patients, 46 (20.5%) patients were smokers, 88 (39.3%) were diabetic and 100 (44.6 %) were reported about their cardiac disease history. 166 patients (78.5%) stated clearly about chest pain at triage, along with their other symptoms ( Table 4 ).

Table 6 Time recorded (in minutes) for Delay care of acute myocardial infarction patients

The triage level 2 should have been designated to a cardiac patient who has severe chest pain and suspicion of acute myocardial infarction. With 180 frequency of patients, 80.35% overall accuracy rate of triage is recorded.

The Delay care was demarcated as the number of minutes a patient waited to be triaged by R.N., number of minutes a patient waited to have an ECG performed, number of minutes' a patient waited to be seen by an E.R. physician, and the number of minutes a patient waited to seen by a cardiologist. Those time points are identified in Table 6 . It is noteworthy that the meantime to triage was recorded 6.75 minutes, the meantime to ECG was 7.30 minutes, the meantime to E.R. physician assessment was 11 minutes, and the meantime to cardiology physician checkup was 25.19 minutes. The recorded time in the current study is significantly inside the recommended guidelines of AHA for cardiac patients.

Discussion

In this study, a total 224 patients were included, 166 (78.5%) of acute myocardial infarction had got triage level 2 designation, which was appropriate. This triage level designation is important in defining how rapidly the patient gets an ECG and is assessed by a healthcare physician. Thus, an accuracy rate of 80% was acceptable but still concerning in terms of patient life. The priority nurse probably had trouble defining the symptoms which characterized ACS. According to Previous studies, the triage accuracy rate was 50% to 76% 15 , 16 , 17 .

This study contains several limitations as it does not explore all the factors, cause and effect of relationship and association among variables which affect the triage decision. Yet, this variation in nurse triage decisions might be due to other circumstance which was not explored, such as priority nurse critical thinking skills, E.D. infrastructure, and decision-making functions. In this study, variables were recognized that might describe accuracy in triage level designations. The patient and R.N. variables were recognized as significant in determining the accuracy of triage designation.

In this study, patients' pictorial description of pain for R.N.s was renowned as an important decision point. Though the accuracy rate was only 80%, a significant relationship was observed between accuracy and chest pain patient reports. Those patients reporting chest pain were more expected to be triaged accurately. It was expected that more patients would present with atypical symptoms and not report chest pain, but only (N = 48) 21.5% reported no chest pain along with other symptoms such as shortness of breath, syncope, palpitations, apprehension, and diaphoresis. In this study, 78.5% reported chest pain in the initial triage documentation. It might be due to the priority nurse question about chest pain; they might give a positive response by considering it a true emergency. As cardiac ischemia main symptom was Chest pain. Therefore, these patients were triaged accurately, which was 80%, and got a level 2 designation, resulting in better triage accuracy in chest pain patients. According to previous reports, the BSN education level has been identified as positively affecting general patient results because the nursing purpose is triage-level designation decisions, which might lead to bad patient consequences 18 , 12 . BSN rather than R.N triaged almost 50% of the patients.

The overall delay occurs in the Emergency Department for acute myocardial infarction patients. However, rapid identification is vital for the initiation of reperfusion therapy in acute myocardial infarction 19 , 20 . The cardiac patient waited, proceeding by priority to initiate the triage assessment, a mean of 6.75 minutes (range 0-13 minutes). Many studies have recognized overall E.D. wait times that are prolonged and fall outside the ESI level recommendations for the right care and better results. In previous studies, the mean delay triage time recorded was 27 min, 26 min, and 14 min, regardless of the severity of chief complaint 21 , 22 , 17 . In the current study, 6.75 min triage meantime, 7.30 min ECG meantime, 11 min E.R. physician assessment meantime, and 25.19 min cardiology resident assessment meantime was recorded. It might be due to better emergency department infrastructure, due to good clinical knowledge and experience of priority nurse and the quality implementation of triage system by E.D. management to get a better outcome in acute myocardial infarction patients.

Conclusion

In this study, the triage level designation accuracy rate and delay care in acute myocardial infarction patients were identified. Triage level designation, ECG delay, E.R. physician assessment delay, and cardiology resident assessment delay were insignificant. Still, triage designation was not accurate in 20% of the patient might lead to a bad outcome in these cardiac patients. Patients who reported chest pain were predictive of better accuracy and did not delay ECG, E.R. physician assessment, and cardiology resident assessment. In patients with acute myocardial infarction symptoms, delays in triage level designation may result in a significant delay in emergent cardiac care.

Similarly, delay in ECG led to a prolonged delay in emergent cardiac care. On the other hand, E.R. physician assessment delays lead to a delay in emergency care. Similarly, the cardiology resident delay assessment delayed getting re-perfusion therapy by acute myocardial infarction, which leads to bad outcomes. This study contains several limitations as it does not explore all the factors, cause and effect of relationship and association among variables which affect the triage decision. Yet, this variation in nurse triage decisions might be due to other circumstance which was not explored, such as priority nurse critical thinking skills, E.D. infrastructure, and decision-making functions. So, it is recommended to evaluate other factors affecting triage level designations decisions and determine the relationship among variables.
