Validity Analysis of Korean Triage and Acuity Scale

PURPOSE: The Korean Triage and Acuity Scale (KTAS), which was developed in 2012 due to the need for a single triage tool for emergency patients in Korea, has since become nationalized. Although five years has passed, there has been limited evidence of its validation. Therefore, this study was conducted to analyze the validity of the new triage system. METHODS: We conducted a multicenter prospective study. Data were collected from seven hospitals and 42,187 patients were classified using the KTAS from April 1, 2013 to July 6, 2014. We analyzed whether the indirect severity variables showed meaningful differences according to KTAS levels. The variables consisted of disposition from emergency room, length of stay, numbers of consultations, examination of computed tomography, emergency room costs, and performance of emergent interventions. RESULTS: From KTAS level 1 to 5, a decreasing trend in the length of stay in emergency room, frequency of consultation with other departments, admission, computed tomography rate, emergency intervention rate, and emergency room costs was observed. Upon binominal logistic regression, disposition from emergency room and emergent intervention rate showed the highest odds ratio with statistical significance. CONCLUSION: The results of this study demonstrated that KTAS is a valid emergency triage tool that reflects the severity of the patient with indirect indicators. The results of this study will be useful as a reference for quality control of KTAS.

Korean Triage and Acuity Scale (KTAS)

The number of patients visiting the emergency room (ER) is increasing every year. The Korean Triage and Acuity Scale (KTAS) was developed in Korea in 2012 to help reduce the congestion of the ER at the hospital level and improve the safety of patients. From January 2016, KTAS has been implemented in emergency medical (EM) centers. KTAS evaluates patients who visit the ER by the following process: impression evaluation, infection confirmation, primary symptom selection, and primary/secondary considerations. KTAS prioritizes patients according to the level, and if necessary, sets a time for which the patient can wait safely with the aim to see a doctor within that time. KTAS has the characteristics of both severity and acuity, so there can be some discrepancy between the KTAS level and disposition. All EM centers conducted the KTAS classification from March to November, 2016. An analysis of the results of the KTAS classification showed no distortion in the classification from the beginning of KTAS introduction. In the near future, it is hoped to develop a KTAS-based transport protocol reflecting the regional medical resources and cultures at the pre-hospital stage, and establish an effective EM system, including medical basis and policy consideration.

Emergency Medical Services in Disasters / 한양의대학술지

Disasters, or mass casualty incidents, occurring in modern history differ from those occurring in even the recent past. In previous times, disasters were mostly the result of natural causes such as earthquakes or floods. Currently, multiple casualty incidents are often the result of human actions such as vehicular accidents involving many vehicles with multiple operators, passengers and collateral victims, terror attacks and acts of war, radiation accidents, toxic chemical releases, and pandemic infectious agent exposures. Especially, events involving accidental and intentional exposures of chemical, biological, radiological/nuclear materials, often abbreviated as CBR or CBRN events present unique challenges to the healthcare system in caring for the victims. In these mass casualty incidents, a fully comprehensive, coordinated team response involving many different components of the community healthcare system need to be mobilized to effectively meet the modern challenge of CBRN events. Necessary components of a modern emergency response include training for prompt triage, decontamination, detoxification, emergency medical treatment, as well as providing appropriate transport to the proper medical treatment facility. Meeting these challenges requires maintaining ongoing communications between agencies charged with meeting the disaster to allow acquisition of information and location for the patients, transfer the information to both the Central Medical Emergency Response Center and the designated hospital. While sharing this information was problematic in the past, modern wireless communications and information technologies provide convenient means for the rapid sharing of important patient data and current situational details. Finally, improving modern disaster response requires the development of a disaster response plan, ongoing training in implementing the plan including disaster scenario simulation, and budgeting to acquire the necessary equipment involved for the emergency response personnel to meet the presenting crisis.

Public Safety Communication and Networking Technologies for Disaster Response and Medical Assistance / 한양의대학술지

Future major disasters require the development of socially transparent and rational-decision-making procedures. Recent reports indicate that the frequency of human disasters are decreasing while natural disasters and social disasters are becoming more frequent. The creation of a disaster communication network, which is essential in protecting the life and property as well as providing a sense of societal security. Standards for a modern disaster communication network must be developed at the national level, with national state support for a 3rd generation partnership project such as a Public Safety-LTE that allows the construction of an effective national disaster network plan. Compliance and certification standards to ensure interoperability of communications and other equipment are necessary for the creation of a modern national disaster network that allows more efficient management of disaster situations. It can be expected that our efforts and example can help other countries to build a standard protocol for managing the national disasters.

Recurrent Pulseless Ventricular Tachycardia Induced by Commotio Cordis Treated with Therapeutic Hypothermia / 대한구급학회지

The survival rate of commotio cordis is low, and there is often associated neurological disability if return of spontaneous circulation (ROSC) can be achieved. We report a case of commotio cordis treated with therapeutic hypothermia (TH) that demonstrated a favorable outcome. A 16-year-old female was transferred to our emergency department (ED) for collapse after being struck in the chest with a dodgeball. She has no history of heart problems. She was brought to our ED with pulseless ventricular tachycardia (VT), and ROSC was achieved with defibrillation. She was comatose at our ED and was treated with TH at a target temperature of 33degrees C for 24 hours. After transfer to the intensive care unit, pulseless VT occurred, and defibrillation was performed twice. She recovered to baseline neurologic status with the exception of some memory difficulties.

The Factors Affecting the Registration Rates for Emergency Department Based Post-suicidal Care Program

PURPOSE: The aim of this study was to investigate the independent factors associated with the registration rate for the community-based post suicidal care program in the emergency department (ED). METHODS: This prospective observational study was conducted between March and December 2013 at the academic ED at the tertiary urban hospital. During the study period, the pre-designed registry was recorded. The variables examined included the following: patients' demographic data (Sex, age, address, type of insurance, marital status, level of education, and history of previous psychiatric disease), suicide-related data (suicidal methods, combined drink of alcohol and number of previous attempts), and management-related data (disposition at ED, physician's training level, etc.). Univariated and multivariated logistic regression analyses were performed for identification of factors affecting the registration rate for the community-based post suicidal care program. RESULTS: A total of 163 suicides were included during the study period. Of these, 33 (20.2%) patients were registered in the post-suicide care program. Factors including a patient's address (OR: 14.92, 95% CI: 3.606-61.711), immediate intervention by psychiatric healthcare center (OR: 5.05, CI: 1.688-15.134), admissions in hospital (OR: 3.69, CI: 1.286-10.605), and history of previous psychiatric disease (OR: 3.52, CI: 1.216-10.201) showed significant association with registration for the program. CONCLUSION: The community-based post-suicidal care program, which is available 24 hours a day, should be operated in each district in order to increase the registration rate. Emergency physicians should actively consider the inpatient treatment program for suicidal patients and strongly recommend registration to the program, particularly for patients without previous history of psychiatric disease.

A Nationwide Survey of Korean Emergency Department Triage Systems and Scales; A First Step Towards Reform of the Emergency Medical Service System

PURPOSE: As a first step towards reform of the emergency medical service system, we aimed to assess the current status of our emergency department triage systems and illustrated the current status and problems of the Korean emergency department triage system. METHODS: We conducted e-mail and telephone surveys of the triage officers of all 136 emergency medical centers in Korea. RESULTS: All 136 emergency departments responded to the survey. In Korea, a triage scale derived from the 'emergency symptoms based on the requirements of the Emergency Medical Service Act' is the most-used triage scale. We identified factors showing significant association with use of verified triage vs. unverified scales, including level of triage scale, type of hospital, type of emergency department, perception of problems regarding the triage scale, educational performance, and number of annual visits. CONCLUSION: Results of our survey showed that in Korea various kinds of triage scale are in use and the reliability and validity of more than half of them are unverified. Reform of the Korean national triage system is in progress and our survey findings should be helpful in guiding reorganization of the national triage systems of many countries.

A Qualitative Study for development of an Informed Consent Form using an iPad in an Emergency Department

PURPOSE: This study identifies best practices for informed consent for emergent computed tomography (CT) scans and development of a new document used to explain the informed consent using an iPad in an emergency department (ED). METHODS: Literature review, semi-structured interviews, and observations of informed consent were used for development of a new process for informed consent. Participants were ED physicians, residents, and senior nurses. Interviews were conducted for identification of agreed best practice and to derive new structural documents for classification of the information into relevant sections. RESULTS: Interviews identified a variety of perceived current deficits in informed consent, including difficult contents and missing explanation of the possible adverse events, such as radiation hazards. Participants provided examples of poor informed consent that were thought to have led to patient dissatisfaction; these included delay for patients who do not agree to undergo CT scan due to brief or inaccurate explanation. The interviewers' responses were used to reach a unifying 'best practice' for the content of informed consent. Their opinions were also used in implementation of a new tool for informed consent using the iPad. CONCLUSION: A new informed consent was developed using an iPad in order to provide a more efficient and organized template, which includes visual information necessary to facilitate understanding. Additional video clips were also developed in order to provide adjuvant materials for detailed explanations.

Use of Backboard and Deflation Improve Quality of Chest Compression When Cardiopulmonary Resuscitation Is Performed on a Typical Air Inflated Mattress Configuration

No study has examined the effectiveness of backboards and air deflation for achieving adequate chest compression (CC) depth on air mattresses with the typical configurations seen in intensive care units. To determine this efficacy, we measured mattress compression depth (MCD, mm) on these surfaces using dual accelerometers. Eight cardiopulmonary resuscitation providers performed CCs on manikins lying on 4 different surfaces using a visual feedback system. The surfaces were as follows: A, a bed frame; B, a deflated air mattress placed on top of a foam mattress laid on a bed frame; C, a typical air mattress configuration with an inflated air mattress placed on a foam mattress laid on a bed frame; and D, C with a backboard. Deflation of the air mattress decreased MCD significantly (B; 14.74 +/- 1.36 vs C; 30.16 +/- 3.96, P < 0.001). The use of a backboard also decreased MCD (C; 30.16 +/- 3.96 vs D; 25.46 +/- 2.89, P = 0.002). However, deflation of the air mattress decreased MCD more than use of a backboard (B; 14.74 +/- 1.36 vs D; 25.46 +/- 2.89, P = 0.002). The use of a both a backboard and a deflated air mattress in this configuration reduces MCD and thus helps achieve accurate CC depth during cardiopulmonary resuscitation.
