Purpose: In this study active surveillance culture for ICU patients, in whom the risk of VRE infection was high were conducted, and through this the VRE colonization rate and the characteristics of the colonization were examined and risk factors involved in VRE colonization and acquisition were analyzed. Method: This research was performed with 635 patients admitted to ICU between July 1 and December 31, 2006. Results: On admission to ICU, the VRE colonization rate was 2.36%, 93% identified from active surveillance culture. The VRE colonization rate was significantly higher in those patients with cancer (OR=9.43; 95% CI=1.38~62.50; P=.022), liver cirrhosis (OR=55.5; 95% CI=7.29~500; P=.005), transferred from other hospitals (OR=200; 95% CI=22.73~1000; P=.000), high APACHE Π score (OR=1.107; 95% CI=1.010~1.213; P=.029), or antibiotics within the last 3 months (OR=15.87; 95% CI=2.27~111.11; P=.005). The VRE acquisition rate was 5.2%. It was significantly higher in those who were using a ventilator (OR=26.31; 95% CI=5.13~142.86; P=.000), three or more kinds of antibiotics during admission (OR=58.82; 95% CI=16.13 ~200; P=.000), or high APACHE Π score (OR=1.16; 95% CI=1.08~1.24; P=.000). Conclusion: The results of this study show that active surveillance culture can detect VRE colonization on admission to ICU and those who have acquired VRE in ICU. The analyzed VRE colonization and risk factors of VRE acquisition are expected to be useful in establishing guidelines for preventing VRE infection in ICU.

Purpose: The increase in patients requiring hemodialysis has resulted in an increase dialysis-associated infections risk. but there are no Renal Dialysis unit design standard meet specified safety and quality standards. Therefore, appropriate Establish standards and legal regulation is important for the provision of initial certification and maintenance of facility, equipment, and human resource quality. Methods: Literature survey on the design guideline and standards of Renal Dialysis unit design in Korea, U.S, Germany, Singapore, Hongkong, Dubai. Results: There are no established standards for facilities in dialysis units in Korea. To prevent infections in dialysis patients, necessary establish standards. Considering the domestic and overseas Health-care facilities standards, the major factors to be considered in the medical environment for Renal Dialysis Unit are as follows. First, planning to separate Clean areas(treatment area) from contaminated areas(medical waste storage area). Second, ensure sufficient space and minimum separation distance. Although there may be differences depending on the circumstances of individual institutions, renal dialysis unit consider the space to prevent droplet transmission. Third, secure infrastructure of infection prevention such as sufficient amount of hand hygiene sinks. Hand washing facilities for staff within the Unit should be readily available. Hand hygiene sinks should be located to prevent water from splashing into the treatment area. Fourth, Heating, ventilation and air conditioning (HVAC) system for Renal Dialysis Unit is all about providing a safer environment for patients and staff. Implications: The results of this paper can be the basic data for the design of the Renal Dialysis Units and relevant regulations.

코로나-19 검사를 위한 음압컨테이너형 선별진료소 CFD 해석
정민지(Minji Jung),한수하(Su Ha Han),유소연(So Yeon Yoo),이재갑(Jacob Lee),홍진관(Jin Kwan Hong) 대한설비공학회 2021 설비공학 논문집 Vol.33 No.2
Fast screening centers are being widely utilized in response to outbreaks and epidemics such as the COVID-19 pandemic. Although various types of screening centers exist, those that use negative pressurized medical rooms have the advantage of being operational regardless of the weather. A computational fluid dynamics (CFD) simulation was used in order to determine the required minimum ventilation rate of a sample collection booth, as well as the corresponding pressure difference between a medical examination room and a sample collection room. In order to prevent cross-contamination between the healthcare worker and testee, the sample collection booth exhaust volume flow rate should be higher than 450 CMH when the sample collection room air change rate is 15 air changes per hour. When maintaining the exhaust volume flow rate at these levels, suspending particles decreased to 2% of the total discharged particles within 2 minutes, and particle removal efficiency reached 99.9% in approximately 6 minutes. Discharged particles were dispersed throughout the sample collection room and deposited on the test subject, chair, sidewalls, ceiling, and floor. Therefore, these results show that surface disinfection should be performed after the testee is tested.

호흡기 감염병 예방을 위한 보건소 상시 선별진료소 활용방안 연구 - 음압 결핵 검진실을 중심으로
윤형진 ( Yoon Hyung Jin ),한수하 ( Han Su Ha ) 한국의료복지건축학회 2021 의료·복지 건축 Vol.27 No.4
Purpose: Tuberculosis(TB) care unit in public health center should be carefully considered to be re-designed as an infection safety environment for both patient and healthcare workers. So, for the enhancement, this study analyses the facility requirements for co-using the screening clinic as a TB and other respiratory disease care unit. Methods: Not only screening clinic facility guidelines from “A Study for Standard Triage Design and Construction Document” but also the guidelines of TB care and related medical facility are reviewed; KDCA, CDC, ECDC and WHO as a TB care, and FGI and NHS for facility. The facility requirements are summarized space, approach, and mechanical requirement in order. By comparing the summary and screening clinic facility guidelines, supplementations are proposed for TB care unit setting. Results: The result of this study shows that both the space program and mechanical requirement of the screening clinic and that of TB care unit are almost identical and could be share, which include direct airflow or negative air pressure in an exam room. To increase functional and economical efficiency, however, it is necessary to consider a multi-functional negative pressured room, So care process may be re-designed based on a room type; face-to-face room or glass wall inbetween. Implications: The facility guidelines for TB care unit of a public health center should be developed to build a safe environment for infection control by reflecting its medical plan and budget.
