Over-triage occurs when considering the patient's pain in Korean Triage and Acuity Scale (KTAS).

Background: The Korean Triage and Acuity Scale (KTAS) was developed based on the Canadian Emergency Department Triage and Acuity Scale. In patients with pain, to determine the KTAS level, the pain scale is considered; however, since the degree of pain is subjective, this may affect the accuracy of KTAS. The purpose of this study was to evaluate the accuracy of KTAS in predicting patient's severity with the degree of pain used as a modifier.

Effects of an emergency transfer coordination center on secondary overtriage in an emergency department.

Background: Patients who cannot be stabilized at a lower-level emergency department (ED) should be transferred to an upper-level ED by emergency medical services. However, some patients are subsequently discharged after transfer without any intervention or admission, and this secondary overtriage (SO) wastes the limited resources of upper-level EDs. This study aimed to investigate whether an emergency transfer coordination center (ETCC) could reduce the risk of SO among patients who were transferred to a tertiary ED by emergency medical services.

Risk score to predict false-positive ST-segment elevation myocardial infarction in the emergency department: a retrospective analysis.

Background: The best treatment approach for ST-segment elevation myocardial infarction (STEMI) is prompt primary percutaneous coronary intervention (PCI). However, some patients show ST elevation on electrocardiography (ECG), but do not have myocardial infarction. We sought to identify the frequency of and to develop a prediction model for false-positive STEMI.

Rapid discrimination of potato scab-causing Streptomyces species based on the RNase P RNA gene sequences.

Scab disease significantly damages potatoes and other root crops. Some Streptomyces species have been reported as potato-scab pathogens. Identification of the phytopathogenic Streptomyces is mainly done on the basis of the 16S rRNA gene, but use of this gene has some limitations for discriminating these strains because they share high similarities of 16S rRNA gene sequences.

Analyses of bacterial communities in meju, a Korean traditional fermented soybean bricks, by cultivation-based and pyrosequencing methods.

Despite the importance of meju as a raw material used to make Korean soy sauce (ganjang) and soybean paste (doenjang), little is known about the bacterial diversity of Korean meju. In this study, the bacterial communities in meju were examined using both culture-dependent and independent methods in order to evaluate the diversity of the bacterial population. Analyses of the 16S rRNA gene sequences of the bacterial strains isolated from meju samples showed that the dominant species were related to members of the genera Bacillus, Enterococcus, and Pediococcus.

A multispecialist teleconsultation system using multiple unicasting.

Multispecialist teleconsultation systems can be particularly useful in obtaining a second opinion from remote medical specialists. In this paper, a multispecialist teleconsultation (MST) system was designed by using multiple unicasting to enable operability over the existing Internet infrastructure and the support of reliable data transmission. The MST was tested over Asynchronous Digital Subscriber Line (ADSL), Very high speed Digital Subscriber Line (VDSL), Wireless Local Area Network (WLAN), and the hospital Local Area Network (LAN) to demonstrate the operability of the designed system over popularly deployed networks that together make up the current Internet.

The usefulness of CT for patients with carpal bone fractures in the emergency department.

Objective: The wrist is the most commonly injured joint in the body. However, wrist injuries are often missed in the emergency department (ED). If the fracture is not diagnosed and remains untreated, the patient runs a considerable risk of chronic disability.

Improved time intervals by implementation of computerized physician order entry-based stroke team approach.

Background: The need for rapid evaluation and treatment of acute stroke patients has been well documented. A computerized physician order entry (CPOE) system can improve communication and provide immediate access to information, which may be useful for an effective team approach program targeted to reduce in-hospital time delays.

Methods: To reduce the time from a patient's arrival at the emergency department to thrombolysis, a team approach program using CPOE was developed, and its efficacy was investigated by comparing time intervals from arrival to evaluation and intravenous tissue-type plasminogen activator (tPA) treatment before and after the implementation of the program.
