A nationwide survey on the implementation of infection prevention and control components in 1442 hospitals in the Republic of Korea: comparison to the WHO Infection Prevention and Control Assessment Framework (IPCAF).

BACKGROUND: The current SARS-CoV-2 pandemic continues to underscore the inadequacy of infection prevention and control (IPC) and the importance of its sound establishment in healthcare facilities. The Infection Prevention and Control Assessment Framework (IPCAF) by the World Health Organization allows systematic assessment of IPC capacity in healthcare facilities and has been applied in many national-level surveys. This study aims to assess the IPC capacity of Korean hospitals as well as their strengths and pitfalls by analyzing the results of the first government-led nationwide IPC survey in comparison to the IPCAF frame. METHODS: The Korean National Infection Prevention and Control Survey (KNIPCS) was conducted from February to March 2018. The survey questionnaire for KNIPCS was developed through a series of expert consultations and a round of pre-testing in two randomly selected hospitals. The survey questionnaire was distributed to a total of 2108 hospitals. Although the survey preceded the release of IPCAF, its contents complied with IPCAF to a large extent, allowing exploration of its results with regards to IPCAF. RESULTS: All tertiary hospitals and 96.5% of general hospitals had implemented IPC teams, whereas the percentage was lower for long-term care hospitals (6.3%). A similar trend was observed for IPC surveillance and monitoring activities across hospital types. The percentage of interactive IPC training was lower than 30% in all hospital groups. Disinfection was frequently monitored in all hospital types (e.g. 97.3% in general hospitals and 85.3% in long-term care hospitals). However, activities regarding antimicrobial resistance, such as multi-drug resistant pathogen screening, were weak in hospitals (25%) and long-term care hospitals (25%), compared to tertiary hospitals (83.3%) and general hospitals (57.7%). CONCLUSIONS: In general, essential IPC structures, such as IPC teams and programs, were well in place in most tertiary and general hospitals in Korea. These hospital groups also actively conducted various IPC activities. As most previous legislative and multimodal policy measures have targeted these hospital groups, we speculate that future policy efforts should encompass long-term care hospitals and smaller-sized hospitals to strengthen the IPC capacity of these hospital groups. Efforts should also be put forth to promote IPC training and antimicrobial activities.

Detection of Novel Coronavirus on the Surface of Environmental Materials Contaminated by COVID-19 Patients in the Republic of Korea.

This study aimed to determine the presence of SARS-CoV-2 on surfaces frequently touched by COVID-19 patients, and assess the scope of contamination and transmissibility in facilities where the outbreaks occurred. In the course of this epidemiological investigation, a total of 80 environmental specimens were collected from 6 hospitals (68 specimens) and 2 "mass facilities" (6 specimens from a rehabilitation center and 6 specimens from an apartment building complex). Specific reverse transcriptase-polymerase chain reaction targeting of RNA-dependent RNA polymerase, and envelope genes, were used to identify the presence of this novel coronavirus. The 68 specimens from 6 hospitals (A, B, C, D, E, and G), where prior disinfection/cleaning had been performed before environmental sampling, tested negative for SARS-CoV-2. However, 2 out of 12 specimens (16.7%) from 2 "mass facilities" (F and H), where prior disinfection/cleaning had not taken place, were positive for SARS-CoV-2 RNA polymerase, and envelope genes. These results suggest that prompt disinfection and cleaning of potentially contaminated surfaces is an effective infection control measure. By inactivating SARS-CoV-2 with disinfection/cleaning the infectivity and transmission of the virus is blocked. This investigation of environmental sampling may help in the understanding of risk assessment of the COVID-19 outbreak in "mass facilities" and provide guidance in using effective disinfectants on contaminated surfaces.

Regional variations in frequency of glycosylated hemoglobin (HbA1c) monitoring in Korea: A multilevel analysis of nationwide data.

PURPOSE: Suboptimal frequency of glycosylated hemoglobin (HbA1c) monitoring is associated with poor diabetes control. We aimed to analyze compliance to HbA1c testing guidelines and explore associated individual and area-level determinants, focusing on regional variation. METHODS: This cross-sectional study between the period of 2012-2013 was conducted by using the Korean National Health Insurance Research Database, and included 45,634 patients diagnosed with diabetes mellitus, who were prescribed any anti-diabetic medications, including insulin. We calculated the proportion of each HbA1c testing frequency (≥1, ≥2, or ≥4 times per year) stratified by 17 administrative regions. Multilevel and multivariate logistic analyses were performed with regional (proportion of farmer population) and individual characteristics (age, sex, income level, duration of diabetes, and most visited medical institution). RESULTS: Overall, 67.3% of the patients received≥1 HbA1c test per year; 37.8% and 6.1% received ≥2 and ≥4 tests per year, respectively. Those managed in secondary-level hospitals or clinics and those living in rural areas were less likely to receive HbA1c testing. Even after adjusting for individual and regional level characteristics, significant area level variation was observed (variance participant coefficients were 7.91%, 9.58%, and 14.43% for testing frequencies of ≥1, ≥2, and ≥4 times a year, respectively). CONCLUSIONS: The frequency of HbA1c monitoring is suboptimal in Korea, especially in rural areas. Moreover, significant regional variation was observed, implying a contextual effect. This suggests the need for developing policy actions to improve HbA1c monitoring. In particular, access to HbA1c testing in rural primary care clinics must be improved.
