ABSTRACT

Objectives@#We aimed to describe the epidemiological characteristics of carbapenemaseproducing Enterobacteriaceae (CPE) outbreaks in healthcare settings in the Republic of Korea between 2017 and 2022. @*Methods@#Under the national notifiable disease surveillance system, we obtained annual descriptive statistics regarding the isolated species, carbapenemase genotype, healthcare facility type, outbreak location and duration, and number of patients affected and recommended interventions. We used epidemiological investigation reports on CPE outbreaks reported to Korea Disease Control and Prevention Agency from June 2017 to September 2022. @*Results@#Among the 168 reports analyzed, Klebsiella pneumoniae (85.1%) was the most frequently reported species, while K. pneumoniae carbapenemase (KPC, 82.7%) was the most common carbapenemase genotype. Both categories increased from 2017 to 2022 (p < 0.01). General hospitals had the highest proportion (54.8%), while tertiary general hospitals demonstrated a decreasing trend (p < 0.01). The largest proportion of outbreaks occurred exclusively in intensive care units (ICUs, 44.0%), and the frequency of concurrent outbreaks in ICUs and general wards increased over time (p < 0.01). The median outbreak duration rose from 43.5 days before the coronavirus disease 2019 (COVID-19) pandemic (2017–2019) to 79.5 days during the pandemic (2020–2022) (p = 0.01), and the median number of patients associated with each outbreak increased from 5.0 to 6.0 (p = 0.03). Frequently recommended interventions included employee education (38.1%), and 3 or more measures were proposed for 45.2% of outbreaks. @*Conclusion@#In the Republic of Korea, CPE outbreaks have been consistently dominated by K. pneumoniae and KPC. The size of these outbreaks increased during the COVID-19 pandemic. Our findings highlight the need for continuing efforts to control CPE outbreaks using a multimodal approach, while considering their epidemiology.

ABSTRACT

OBJECTIVES@#This study aimed to determine an effective survey method for the accurate calculation of obesity prevalence by comparing the self-reported and measured height, weight, and body mass index (BMI) using the 2018 Korea Community Healthy Survey (CHS) data. @*METHODS@#Raw data from the 2018 CHS were used to analyze the differences, correlation, and agreement between self-reported and measured height, weight, and BMI. @*RESULTS@#The self-reported height was over-reported than the measured height (0.59 cm greater for men and 0.71 cm greater for women), while the self-reported weight was under-reported than the measured weight (0.55 kg less for men and 0.67 kg less for women). Subsequently, the self-reported BMI was under-estimated (0.35 kg/m2 lower for men and 0.49 kg/m2 lower for women) compared with the measured BMI. The kappa statistic and agreement between measured and self-reported values per BMI category (underweight, normal, overweight, and obesity) were 0.82 and 79.6%, respectively. @*CONCLUSIONS@#The prevalence of obesity should be calculated using the measured values provided in the CHS in order to promote local health projects based on accurate evidence.

ABSTRACT

Objectives@#This study aimed to disseminate information on coronavirus disease 2019 (COVID-19) vaccine safety among adolescents aged 12 to 17 years in the Republic of Korea. @*Methods@#Two databases were used to assess COVID-19 vaccine safety in adolescents aged 12 to 17 years who completed the primary Pfizer-BioNTech vaccination series. Adverse events reported to the web-based COVID-19 vaccination management system (CVMS) and collected in the text message-based system were analyzed. @*Results@#From March 5, 2021 to February 13, 2022, 12,216 adverse events among 12- to 17-year-olds were reported to the CVMS, of which 97.1% were non-serious adverse events and 2.9% were serious adverse events, including 85 suspected cases of anaphylaxis, 74 suspected cases of myocarditis and/or pericarditis, and 2 deaths. From December 13, 2021 to January 26, 2022, 10,389 adolescents responded to a text message survey, and local/systemic adverse events were more common after dose 2 than after dose 1. The most commonly reported events following either vaccine dose were pain at the injection site, headache, fatigue/tiredness, and myalgia. @*Conclusion@#The overall results are consistent with previous findings; the great majority of adverse events were non-serious, and serious adverse events were rare among adolescents aged 12 to 17 years following Pfizer-BioNTech COVID-19 vaccination.

ABSTRACT

Objectives@#This study aimed to present data on reported adverse events following coronavirus disease 2019 (COVID-19) vaccination in Republic of Korea from February 26 to October 31, 2021, and to determine whether any significant patterns emerged from an analysis of the characteristics of suspected adverse event cases for each type of vaccine. @*Methods@#Adverse events following COVID-19 vaccination reported by medical doctors and forensic pathologists were analyzed. Cases of suspected anaphylaxis were classified using the Brighton Collaboration definition. @*Results@#By October 31, 2021, a total of 353,535 (0.45%) adverse events were reported after 78,416,802 COVID-19 vaccine doses. Of the adverse events, 96.4% were non-serious and 3.6% were serious. The most frequently reported adverse events were headache, myalgia, and dizziness. Of the 835 reported deaths after COVID-19 vaccination, 2 vaccine-related deaths were confirmed. Suspected anaphylaxis was confirmed in 454 cases using the Brighton Collaboration definition. @*Conclusion@#The commonly reported symptoms were similar to those described in clinical trials. Most reported adverse events were non-serious, and the reporting rate of adverse events following COVID-19 vaccination was higher in women than in men (581 vs. 315 per 100,000 vaccinations). Confirmed anaphylaxis was reported in 5.8 cases per 1,000,000 vaccinations.

ABSTRACT

Objectives@#On February 26, 2021, coronavirus disease 2019 (COVID-19) vaccination was started for high-priority groups based on the recommendation of the Advisory Committee on Immunization Practices with 2 available COVID-19 vaccines (AstraZeneca and Pfizer-BioNTech) in Korea. This report provides a summary of adverse events following COVID-19 vaccination as of April 30, 2021. @*Methods@#Adverse events following immunization are notifiable by medical doctors to the Korea Immunization Management System (KIMS) under the national surveillance system. We analyzed all adverse events reports following COVID-19 vaccination to the KIMS from February 26 to April 30, 2021. @*Results@#In total, 16,196 adverse events following 3,586,814 administered doses of COVID-19 vaccines were reported in approximately 2 months (February 26 to April 30, 2021). Of these, 15,658 (96.7%) were non-serious adverse events, and 538 (3.3%) were serious adverse events, including 73 (0.5%) deaths. The majority of adverse events (n=13,063, 80.7%) were observed in women, and the most frequently reported adverse events were myalgia (52.2%), fever (44.9%), and headache (34.9%). Of the 73 deaths following the COVID-19 vaccination, none were related to the vaccines. @*Conclusion@#By April 30, 3.6 million doses of the COVID 19 vaccine had been given in Korea, and the overwhelming majority of reports were for non-serious events. The Korea Disease Control and Prevention Agency continues to monitor the safety of COVID-19 vaccination.

ABSTRACT

The Korea National Health and Nutrition Examination Survey (KNHANES) was initiated in 1998 to provide evidence for the development and evaluation of health policies and programs. The Korea Disease Control and Prevention Agency is responsible for the KNHANES and has conducted it as a series of surveys. Over the past 20 years, efforts to produce accurate, timely, and nationwide health statistics have been refined by establishing a continuous annual survey system with full-time field staff, incrementally expanding survey components, collaborating with relevant academic societies for quality control, and revising the survey methods. Additionally, the utility of the collected data was increased by linking the KNHANES data with related data from other government agencies or institutions and making the overall data publicly available on the official website of KNHANES (https://knhanes.kdca.go.kr). Additional long-term plans are being developed, including plans to continue producing nationwide health indicators and invigorating the utilization of the KNHANES data.

ABSTRACT

OBJECTIVES@#The purpose of this study was to estimate the incidence of injuries and to identify their causes by classifying injuries according to various categories including age, sex, mechanism of injury, body parts injured, and place of injury. @*METHODS@#This study used data from the Korea National Hospital Discharge In-depth Injury Survey (KNHDIS) from 2004 to 2016. The KNHDIS is conducted annually by the Korea Centers for Disease Control and Prevention, and its survey population includes all hospitalized patients discharged from medical institutions that have 100 or more beds, such as hospitals, general hospitals, and secondary community health centers. The number of injured cases is weighted and estimated using the mid-year estimated population of each year. @*RESULTS@#The injury discharge rate steadily increased since 2004 (1,505 per 100,000 population in 2004, 2,007 per 100,000 population in 2016) and most injuries were unintentional (annual average of 94.7%). On average, during the 13-year study period, the injury rate for males was 1.5 times as high as for females. The 2 main causes of injury were consistently traffic accidents and falls. Notably, the rate of injuries resulting from falls rose by 1.7-fold from 463 to 792 per 100,000 people, and exceeded the rate of traffic accidents in 2016. @*CONCLUSIONS@#The incidence of injuries steadily increased after the survey was first conducted, whereas mortality resulting from injuries mostly remained unchanged. This suggests that effective strategies and interventions should be reinforced to reduce unintentional injuries.

ABSTRACT

This study compared interview and telephone surveys to select the better method for regularly estimating nationwide vaccination coverage rates in Korea. Interview surveys using multi-stage cluster sampling and telephone surveys using stratified random sampling were conducted. Nationwide coverage rates were estimated in subjects with vaccination cards in the interview survey. The interview survey relative to the telephone survey showed a higher response rate, lower missing rate, higher validity and a less difference in vaccination coverage rates between card owners and non-owners. Primary vaccination coverage rate was greater than 90% except for the fourth dose of DTaP (diphtheria/tetanus/pertussis), the third dose of polio, and the third dose of Japanese B encephalitis (JBE). The DTaP4: Polio3: MMR1 fully vaccination rate was 62.0% and BCG1:HepB3:DTaP4:Polio3:MMR1 was 59.5%. For age-appropriate vaccination, the coverage rate was 50%-80%. We concluded that the interview survey was better than the telephone survey. These results can be applied to countries with incomplete registry and decreasing rates of landline telephone coverage due to increased cell phone usage and countries. Among mandatory vaccines, efforts to increase vaccination rate for the fourth dose of DTaP, the third dose of polio, JBE and regular vaccinations at recommended periods should be conducted in Korea.

ABSTRACT

The Health Interview Survey in the Korean National Health and Nutrition Examination Survey is a major source for planning and evaluating the national health promotion policy. The aim of the study is to find the areas for improvement of the current Health Interview Survey in light of its stated purpose and to propose possible means for the improvement. In terms of the survey content, there were several areas that needed improvement: the lack of comparability across the waves, the limit of the number of questions due to the Nutrition Survey and the Examination Survey, non-availability of seasonal statistics, and the dearth of evidence on socioeconomic position variables. To make improvements in the survey content, there is a need to clarify the purpose of the HIS in the KNANES. Second, more items need to be developed to produce the indicators of the Health Plan 2010. Third, core questions and elective questions should be defined. Fourth, multi-level socioeconomic position indicators need to be developed. In terms of the survey methods, the difficulty of managing interviewers and the inefficiency of data input and processing were found to be the areas for improvement. Possible solutions include a survey through the year and the introduction of the CAPI system. In addition, we suggest that a two-year survey period to better synchronize with the local health interview surveys which should be the major data source for the community health promotion plan.

ABSTRACT

PURPOSE: This study was conducted to improve the Korean influenza management system and to determine the status of influenza vaccination in some community health centers through a survey of the officers in charge of influenza vaccination. METHODS: The authors conducted a questionnaire survey by e-mail for the officers in charge of influenza vaccination of 8 community health centers in Daegu-si, 5 community health centers in Ulsan-si and 25 community health centers in Gyeongsangbuk-do. The authors developed a questionnaire including selection methods of the influenza vaccination objects, results of influenza vaccination in 2002, problems of influenza vaccination, the population within the respondents`jurisdiction and so on. RESULTS: The proportion of influenza vaccination at community health centers among all residents in the 2002-2003 influenza season was 3.8% in Daegu-si, 14.8% in Ulsan-si, 15.1% in urban Gyeongsangbuk-do and 24.9% in rural Gyeongsangbuk-do. The proportion of influenza vaccination at community health centers among priority cases for vaccination was 12.9% in Daegu-si, 43.1% in Ulsan-si, 39.3% in urban Gyeongsangbuk and 41.6% in rural Gyeongsangbuk-do. The officers in charge of influenza vaccination stated that the problems of influenza vaccination were deficiencies in preparatory examination such as manpower shortage. Twenty-five persons stated as a problem that influenza vaccinations conducted in the hospitals were hardly reported, and fifteen of these clarified that this was due to hospital indifference. CONCLUSIONS: The authors examined all community health centers of Daegu-si, Ulsan-si, and Gyeongsangbuk-do, and investigated the vaccination states and problems that health officers were dealing with. Therefore, this study is meaningful with its basic data for the management of domestic influenza vaccination.

ABSTRACT

We surveyed 343 female bank clerks to find out associations between stress and a variety of factors including general, menstruation and reproductive characteristics of the participants. Unmarried women composed the majority of younger, lower income and lower education groups than married did. They also showed higher. though not significantly higher, scores for psychosocial well being index(PWJ) and the first three items of the stress survey. And married women scored slightly higher only in the fourth item of the stress survey. Among the subgroups of married and unmarried women, many factors contributed to a higher stress score in two or more items of the stress survey; in unmarried women, lower education level, little physical exercise, and large family inhabitants, in contrast married women, higher monthly income and greater working hours were related to higher stress scores. According to the menstruation factors, subgroups with dysmenorrhea or irregular cycle and scanty bleedig volume in unmarried women and subgroups with dysmenorrhea in married women showed higher stress scores in PWI. In married women, the proportion of those who have been pregnant was 77.2% and the proportion of those who have experienced spontaneous abortion was 24.1%. Those who have ever experienced two or more spontaneous abortion showed higher, though not statistically significantly higher. scores for PWI. In conclusion, dysmenorrhea was associated with high stress score in two groups. And the other factors related to higher score of PWJ were different between unmarred and married women, which should be considered in a management plan for mental health promotion.

ABSTRACT

To investigate the exposure levels of organic solvents and subjective symptoms of dry-cleaning workers, 77 male and 52 female dry-cleaning workers who had been worked in a small city of Chungnam province, and a large city, Taejon were selected for the study group. Air concentrations of organic solvents in the working environment were analyzed, and subjective symptoms of dry-cleaning workers were surveyed, from July to August 1996. The results obtained were as follows: 1. The concentrations of organic solvents in the working environment were within permissible TLV-TWA limits. 2. For the 13 symptom clusters, the most frequently complained symptom clusters were fatigue as 71.3%, and followed by depression and urinary disturbances as 53.5% and 51.9%. Other symptom clusters complained were below 50%. 3. Positive response rates of subjective symptoms were significantly higher in worker groups such as lived in a large city, female, higher education level, more frequently alcohol drinking, higher concentration of organic solvent in working environment, work in alone. 4. Workers who had used solvent B showed 2.3 point higher scores of subjective symptoms than those of solvent A. Of the subjective symptoms scores, amnesia and nervousness were higher in solvent B user group than solvent B user group. 5. As a result of factor analysis, 3 factors such as depression, urinary disturbance and neurologic disturbance were selected. 6. As a result of the logistic regression analysis, sex, the number of fellow workers, working time, region, job tenure, smoking, alcohol drinking, ventilating system, concentration of organic solvent in working environment and place of residence were selected for the related variables For the conclusion, even though the concentrations of organic solvents in the working environments of dry-cleaning workers were within permissible limit of TLV-TWA, many dry-cleaning workers complained symptoms, such as fatigue, depression, urinary disturbances and so on. And the factors affecting to the symptoms of dry-cleaning workers were the number of fellow workers, work hours, region, job tenure, smoking and alcohol drinking.
