Nationwide Results of COVID-19 Contact Tracing in South Korea: Individual Participant Data From an Epidemiological Survey.

ABSTRACT: BACKGROUND:Evidence regarding the effectiveness of contact tracing of COVID-19 and the related social distancing is limited and inconclusive. OBJECTIVE:This study aims to investigate the epidemiological characteristics of SARS-CoV-2 transmission in South Korea and evaluate whether a social distancing campaign is effective in mitigating the spread of COVID-19. METHODS:We used contract tracing data to investigate the epidemic characteristics of SARS-CoV-2 transmission in South Korea and evaluate whether a social distancing campaign was effective in mitigating the spread of COVID-19. We calculated the mortality rate for COVID-19 by infection type (cluster vs noncluster) and tested whether new confirmed COVID-19 trends changed after a social distancing campaign. RESULTS:There were 2537 patients with confirmed COVID-19 who completed the epidemiologic survey: 1305 (51.4%) cluster cases and 1232 (48.6%) noncluster cases. The mortality rate was significantly higher in cluster cases linked to medical facilities (11/143, 7.70% vs 5/1232, 0.41%; adjusted percentage difference 7.99%; 95% CI 5.83 to 10.14) and long-term care facilities (19/221, 8.60% vs 5/1232, 0.41%; adjusted percentage difference 7.56%; 95% CI 5.66 to 9.47) than in noncluster cases. The change in trends of newly confirmed COVID-19 cases before and after the social distancing campaign was significantly negative in the entire cohort (adjusted trend difference -2.28; 95% CI -3.88 to -0.68) and the cluster infection group (adjusted trend difference -0.96; 95% CI -1.83 to -0.09). CONCLUSIONS:In a nationwide contact tracing study in South Korea, COVID-19 linked to medical and long-term care facilities significantly increased the risk of mortality compared to noncluster COVID-19. A social distancing campaign decreased the spread of COVID-19 in South Korea and differentially affected cluster infections of SARS-CoV-2.

Project description:BackgroundIn South Korea, community pharmacy experiential practice (CPEP) is very important because most pharmacists (71.8%) work in community pharmacies, which also employ the majority of students after graduation. The present study investigated student responses to the current CPEP status, suggestions for improvement, and advancement in their competency after practice based on evaluation of Community Pharmacy Experiential Practice Model (CPEPM) outcomes.MethodsA nationwide cross-sectional, self-administered online survey was conducted in 2017 for the sixth-year pharmacy students who completed CPEP, using 50 item questionnaire. The answers were evaluated using the 4-point Likert scale, used a scoring system from 1 (strongly disagree) to 4 (strongly agree). Responses of 1 and 2 were considered negative, and 3 and 4 were considered positive. To identify factors affecting CPEPM outcomes, multivariate linear regression analysis was performed.ResultsInitially, 1138 students participated in the survey. Of these, responses from 492 students were excluded due to missing data and eventually, data from 646 students were included in the analysis. In total, 95% of students responded in the affirmative that practical training influenced their future career decision. In addition, 78.5% of students were satisfied with the training. Further, they responded that their ability improved based on CPEPM outcomes. The most positive capability change was in the subdomain "personal and professional development", followed by "inter professional collaboration".ConclusionsStudents responded with the higher rating for satisfaction factor, who regarded CPEP as helpful in future career decision making, and those who wanted to practice elective Advanced Pharmacy Practice Education at a community pharmacy had a positive CPEPM outcome, while age was found to be a negative factor in terms of the regression analysis. These are valuable findings as they represent the current student perception of CPEP nationwide. They provide a basis to improve the quality of CPEP-based education not only in Korea, but in other countries as well.

Project description:BACKGROUND:Intussusception is a gastrointestinal condition in which early treatment is critical. Although its epidemiology and comorbidities have been studied, few studies have included the entire pediatric population of a country. Therefore, we aimed to analyze the epidemiologic features of pediatric intussusception patients and identify comorbidities associated with intussusception in South Korea, using the public health database. METHODS:We analyzed the data of children below 18?years of age, from the national database of South Korea, who were diagnosed with intussusception and managed such as air reduction or surgical methods from 2008 to 2016. Patients were categorized into six groups based on the comorbid diseases. Patients with structural lesion in gastrointestinal tract were divided diagnosis or diagnosis code. RESULTS:The number of patients diagnosed with intussusception were 25,023 (16,024 males, 64.0%). Of them, the highest percentage was patients aged between 2 and 36?months (20,703; 82.7%). The incidence per 100,000 individuals aged up to 2?years was 196.7. The number of males were 16,024 (64.0%) and were almost twice the number of 8999 (36.0%) female patients. The maximum number of cases (n =?2517; 10.1%) were seen in September, followed by July (n =?2469; 9.9%). In February, the number of cases was lowest at 1448 (5.8%) patients (P <?0.001). The number of patients with structural lesions of the gastrointestinal tract that could lead to intussusception was 1207 (4.8%), while patients with acute gastrointestinal infectious disease were 4541 (18.1%). Among the structural lesions of the gastrointestinal tract that could be the leading cause of intussusception, lymphadenopathy was the most common, seen in 462 (56.6%) patients and an appendix-related condition was seen in 260 (31.9%) patients. Infectious diseases were more common in the younger children, while systemic diseases were more common in the older. CONCLUSION:We confirmed that pediatric intussusception in South Korea shows a seasonal tendency, which is age-dependent and is associated with an exposure to infectious agents. Some infectious pathogens and underlying diseases might play an important role in the pathophysiology of intussusception.
