The purpose of this study was to determine whether the results of KTAS(Korean Triage and Acuity Scale) triage classifier differ according to the occupations. We analyzed a total of 10,960,359 cases of data sent to the NEDIS from January 1st, 2016 to December 31th, 2017. The triage classifier were MD(Medical Doctor), R(Resident), INT(Intern), GP(General Practitioner), RN(Registered Nurses) and EMT(Emergency Medical Technician). The consistency between the initial triage and final triage results was the highest GP(98.9%) and the lowest INT(80.2%). The results of over-triage classification was the lowest by GP(0.6%) and the highest for INT(16.0%). Also, the results of under-triage classification was the lowest by MD, EMT(0.4%) and the highest for INT(3.8%). The results of KTAS triage classifier significantly differ from according to the occupations(p<0.001). Triage classification should not differ from according to occupations and skill. It is necessary to strengthen the classifier's capacity for accurate triage classifications.

It is important to check the types of drugs when treating acute drug intoxication. This study researches the clinical characteristics and types of patients hospitalized in emergency medical center for drug addiction in 2009 and 2010. By applying a drug addiction selecting kit, it studied the flexibility and clinical efficiency during diagnosis and treatment. The study result shows, among the drugs causing addiction, Sedative accounts for 34.4%, Herdicide 23.5%, Analgesic 17.2%, Insectide 7.8% and else 17.2%. Sedative showed the highest proportion both in 2009 and 2010. Among the drug addicted patients, 39 cases did not know that the drugs are poisonous and among them, the drug addiction selecting kit was positive in 32 cases (82.0%). In 42 cases where addiction was suspicious, 25 cases (59.5%) were positive in the drug addiction selecting kit. In 57 cases of using drug addiction selecting kits, the cases in which benzodiazepine was positive, were 30 and the most frequently cases were as follows; Tricyclic Antidepressants (TCA) 13 cases, Amphetamines 3 cases, barbiturate 3 cases, and piate 3 cases. In the district using drug addiction kit meaningfully had Flumazenil injection much greater impact than the one not using the kit. This proves the efficiency of the kit (p<0.05). The uses of drug addiction selecting kits are for acute drug intoxicated patients and for providing objective and scientific information when emergency medical doctor are checking unchecked poisoning drugs. It is considered that drug addiction selecting kits would give help when treating the early stage of drug addicted patients in emergency medical treatment.

The disasters in Korea, such as the Sewol Ferry Ship sinking disaster has had problems related to the medical response system, with the problems of emergency medical support team in the site, the cooperation between medical staff and fire department officer at disaster site, field medical support and hospital acceptance of the wounded in trouble, the lack of specific systematic medical response manual. Therefore, from May 2014, when the disaster emergency information center in Central Emergency Medical Center starts, collection, modification and education of scattered preexisting disaster emergency medical manual had appeared as important issues. So, it was necessary to develop the early medical response system to disaster. The correction planning of disaster emergency medical response system by Central Emergency Medical Center included quick response system with the fast medical team operation, but the practical application was not enough. So the researcher and his team developed the first Korean disaster emergency medical response manual and the process of development was documented and arranged with the application by education and training.

Purpose: This study aimed to identify the factors that contribute to head injuries among drivers of personal mobility devices and provide insights into safety perceptions. Methods: This retrospective study analyzed data of 221 trauma patients obtained from electronic medical records and the National Emergency Department Information System (NEDIS) over one year, from August 1, 2021, to July 31, 2022. The patients, all in their 20s and 30s, presented to a single emergency medical center following personal mobility device accidents (motorcycles, electric scooters, and bicycles). Results: Among motorcycle riders, 18.2% were not wearing helmets, while the percentage of e-scooter riders not wearing helmets was 87.5%. Wearing a helmet was associated with a 71.2% lower likelihood of head injuries (OR=0.288, CI=0.163 to 0.509, p=0.000). Of the personal mobility devices, motorcycles had a 0.431 times lower odds ratio for head injury compared to e-scooters (p=0.009), and there was no significant difference between e-scooters and bicycles (p=0.776). Conclusion: It is imperative to strengthen safety regulations by mandating helmet use for riders of personal mobility devices. A system to enhance driving enforcement for electric scooters, which are increasingly popular among young adults, should also be established.

Purpose: The objective of this study was to determine the appropriateness of Emergency Medical Service's (EMS's) triage and transport of severely injured patients in Busan and Kyungnam, Korea. Methods: The medical records of the Emergency Medical Information Center were retrospectively reviewed from January 1, 2010 to December 31, 2010. We identified the number of patients that should have been transferred from a secondary to a tertiary hospital according to the EMS field triage protocol. Results: In a total of 472 cases requests to be transferred to a third hospital were made through the Emergency Medical Information Center. Of these, 207 patients(43.9%) should have been transferred to a tertiary hospital according to the EMS field triage protocol. Among them, thirty-three(15.9%) patients satisfied step 1, 15(7.0%) satisfied step 2, and 117(56.5%) satisfied step 3. Twenty-three(11.1%) patients satisfied both steps 1 and 3. Conclusion: We found the triage by the EMS in the transfer of severely injured patients to a tertiary hospital to be inappropriate and re-education of EMS personnel regarding the EMS field triage protocol is needed. Because many patients are transferred from a secondary to a third hospital, we suggest changing the EMS field triage protocol to expand the severe injury criteria. A need exists to authorize secondary hospitals to transfer severely injured patients directly because there are no trauma centers in Korea.

In this paper, we designed bio-signal acquisition system in Magnetic Resonance Imager(MRI) Environment. In MRI Environment, Strong RF Pulse and Gradient Field Switching Noise exist and can cause distortion of ECG. By this, ECG can lose their important information. So we proposed a bio-signal acquisition system with robust immunity to RF pulse and gradient switching noise. In conclusions, the proposed system showed the prevent saturation of measured biosignal and possibility of using cardiac gating and respiration gating method.

The proposed application design for emergency medical system includes the functions that help securing the window of opportunity for the patients in an emergency situation and efficiently link rescue agency, emergency medical treatment center and patients together. First, the treatment time can be saved at the emergency room by understanding the patient's condition by entering his/her health information such as anamnesis, family history, social history and blood type together with an identification number. Also, if the siren function which signals whereabouts of patients to the rescue crew is used, it will be much easier to find the location of the patient in need. The design allows rescue crew to call the patient to check whether he/she is conscious or not. Just by receiving the call, he/she will be deemed conscious.

Purpose: This research was done to identify the hospital arrival rate and factors related to prehospital delay in arriving at an emergency medical center within the golden time after symptom onset in patients with acute myocardial infarction (AMI). Methods: Data used in the research was from the National Emergency Department Information System of the National Emergency Medical Center which reported that in 2014, 9,611 patients went to emergency medical centers for acute myocardial infarction. Prehospital time is the time from onset to arrival at an emergency medical center and is analyzed by subdividing arrival and delay based on golden time of 2 hour. Results: After onset of acute myocardial infarction, arrival rate to emergency medical centers within the golden time was 44.0%(4,233), and factors related to prehospital delay were gender, age, region of residence, symptoms, path to hospital visit, and method of transportation. Conclusion: Results of this study show that in 2014 more than half of AMI patients arrive at emergency medical centers after the golden time for proper treatment of AMI. In order to reduce prehospital delay, new policy that reflects factors influencing prehospital delay should be developed. Especially, public campaigns and education to provide information on AMI initial symptoms and to enhance utilizing EMS to get to the emergency medical center directly should be implemented for patients and/or caregivers.
