정선영,오향순,천희경 보건의료산업학회 2015 보건의료산업학회지 Vol.9 No.4

Objectives : This study was conducted to measure the effects of healthcare accreditation (HA) on the changes in infection control (IC). Methods : Questionnaires were e-mailed to 60 hospitals from 23 October to 23 December, 2011. Data were analyzed by SPSS 12.0. Results : Finally 50 hospitals (83.0%) were enrolled in the study: Seoul area (40.0%), tertiary (76.0%), and >500 beds (98.0%). Nine hospitals (18.0%) had a full time infection control nurse[ICN] with 300 beds. Among various factors, ICN (36.0%), hospital facilities (66.0%), instruments (32.0%) and supplies (88.0%) all improved. Hand hygiene increased (53.1% vs 83.2%, p<.001), but it was continued only in 34.1% of hospitals. Healthcare-associated infection (68.4%), multi drug resistant organisms (42.1%) and outbreaks (26.3%) decreased. Reasons for difficulties in satisfying the HA standards were inadequate support which included hospital facilities, instruments, budget, and a shortage of ICNs and healthcare workers (HCWs). Conclusions : HA had effects on the IC, but they were transient. Staffing in ICN and HCW staffing, hospital facilities, instruments, and supplies all need to be improved.

차경숙,신명진,이지영,천희경 대한의료관련감염관리학회 2017 의료관련감염관리 Vol.22 No.1

Background: The aim of this study was to examine in detail the difficulties infection control nurses (ICN) experience in their work, and to investigate their roles during Middle East Respiratory Syndrome (MERS) outbreaks, using qualitative methods.Methods: Two focus groups were formed by convenience sampling of eight infection control nurses from each of the hospitals where patients with suspected or confirmed MERS were hospitalized and from those hospitals where no MERS cases were found. One interview each was conducted for both of focus groups in November 2015. Contents of the focus group discussions were analyzed for the investigated features and categories.Results: When MERS outbreaks occurred, ICNs provided suggestions on applications of policies, rules and procedures, reporting and communication; participated in education and trainings, consultations, detection and monitoring of MERS cases; and controlled infection among staff. Depending on the type of work, they had various roles such as coordinator, decision maker, administrator, information provider, educator, leader, consultant, and epidemiological investigator.Conclusion: Infection control nurses performed various tasks and played an important role during a MERS outbreak. They experienced difficulties at a personal level as well as in their work environment. Therefore, it is necessary to provide a systematic education program to enhance ICNs competency, while clearly defining their role to help them cope with the infection crisis effectively. In addition to the national level, a system for self-supporting medical institutions should be established.

박진주,서유빈,김성란,박혜진,엄중식,유현미,천희경 대한의료관련감염관리학회 2019 의료관련감염관리 Vol.24 No.1

Background: Catheter-associated urinary tract infection is a major infection in healthcare facilities. We investigated the urinary catheter utilization ratio and incidence of catheter-associated urinary tract infections in small-sized hospitals with ≤300 beds. Methods: We recruited hospitals via a web-based survey from July 2016 to September 2016. Infection control practitioners provided data about catheter-associated urinary tract infections on the website according to the prescribed form. The urinary catheter utilization ratio was calculated by dividing the number of device-days by the number of patient-days. The incidence of catheter-associated urinary tract infections per 1,000 device-days was calculated by dividing the number of urinary tract infections in patients with indwelling urinary catheter by the number of indwelling device-days and multiplying by 1000. The urinary catheter utilization ratio and incidence of catheter-associated urinary tract infections were compared between hospitals with >200 beds and ≤200 beds.Results: Twenty-seven hospitals were included. The average urinary catheter utilization ratio was 0.4 (0.47 in hospitals with >200 beds and 0.38 in hospitals with ≤200 beds; P=0.1). The incidence of catheter-associated urinary tract infections was 1.59 per 1,000 device-days. There was no significant difference in the incidence of infections according to the number of beds (1.53 in hospitals with >200 beds vs 1.9 in hospitals with ≤200 beds, P=0.421). Conclusion: The incidence of catheter-associated urinary tract infections in small-sized hospitals was considerably high. Efforts must be made to attenuate the infection rates through proper infection control and monitoring.

단일 3차 의료기관 집중치료실에서 발생한 다약제내성 Acinetobacter baumannii의 4례

이경석,차성호,이규민,윤회수,정사준,천희경 대한소아감염학회 2011 Pediatric Infection and Vaccine Vol.18 No.1

The Multidrug-resistant Acinetobactor baumanii (MDRAB) is an opportunistic pathogen. Patients with long periods of hospital stay and/or under intensive care unit (ICU) receiving invasive management are more susceptible to this pathogen. In this report, four children with MDRAB infection are reviewed and described their clinical characteristics. There had been concurrent outbreaks of MDRAB infection in adult patients in the ICU at this period of time. The first child had received a craniotomy and epidural hematoma evacuation. The second child was admitted for status epilepticus with hydrocephalus. The third child had pneumonia with status epilepticus with hydrocephalus. The fourth child had poor activity due to hypoxic ischemic encephalopathy and convulsive disorder. Except the fourth child, all had not been exposed to carbapenem prior to infection of MDRAB. That imply the cause of MDRAB infections may be associated with invasive management and prolonged hospitalization together with the previous exposure to carbapenem in our cases. We would like to emphasize the importance and minimizing the spread of hospital infection in patients under prolonged intensive care management regardless of the use of carbapenem. Acinetobactor baumanii는 기회 감염균으로 carbapenem의 사용이 증가하면서 MDRAB와 같은 내성균으로 출현하고 있다. 저자들은 경희의료원에서 carbapenem 을 투약받지 않았더라도 집중치료실에 장기간 입원하여 기관삽관과 인공호흡기 치료를 받거나 침습적인 수술을 받아 도관을 유지하는 환아에서 MDRAB가 동정되었다는 것을 확인하였다. carbapenem을 사용하지 않았더라도 장기간 집중치료실에 입원할 것으로 예상되는 환자들에게 원내전파를 통한 감염을 최소화하기 위하여 원내 감염관리에 최선을 다해야 할 것이기에 이상의 증례를 통하여 보고한다.

Background: This study was conducted to investigate the educational needs of employees in charge of practical services at postpartum care centers and to test the improvement of infection control-related knowledge after developing and implementing educational programs that reflect their needs. Methods: On the basis of research of the literature on educational requirements and consultations with researchers and experts, we developed educational programs on infection control. A total of 136 postpartum care workers participated in the program. To assess the effectiveness of the program, the degree-of-knowledge and satisfaction of the program were measured before and after the education. The educational program consisted of four themes over 200 minutes (50 minutes each). Results: After training, the participants’ overall infection control knowledge increased from 84.36 points to 89.04 points. The participants were satisfied with the program; they were satisfied with their knowledge acquisition (4.59±0.66 points), with the practical application of the content (4.59±0.65 points), and with the education program itself (4.52±0.67 points). Conclusion: As the positive effects of the educational program have been identified, the program can be extended to all postpartum care workers. Continuous development and implementation of educational programs are necessary to strengthen the capability of postpartum care workers, allowing them to effectively manage infection in the future.
