Developing a framework for regular and sustainable qualitative assessment of antibiotic use in Korean medical institutions: a Delphi study.

BACKGROUND: We aimed to develop a roadmap for conducting regular, sustainable, and strategic qualitative assessments of antibiotic use in medical institutions within the Republic of Korea. METHODS: A literature review on the current state of qualitative antibiotic assessments was conducted, followed by one open round to collect ideas, two scoring rounds to establish consensus, and one panel meeting between them. The expert panel comprised 20 experts in infectious disease or antibiotic stewardship. RESULTS: The response rate for all three surveys was 95% (19/20), while the panel meeting attendance rate was 90% (18/20). The following long-term goals were defined to assess the annual use of antibacterial and antifungal agents in all medical institutions, including clinics. The panel agreed that random sampling of antibiotic prescriptions was the most suitable method of selecting antibiotics for qualitative assessment, with the additional possibility of evaluating specific antibiotics or infectious diseases that warrant closer evaluation for promoting appropriate antibiotic use. The plan for utilization of results from evaluation involves providing feedback while maintaining anonymity and disclosure. It includes a quantitative assessment of antibiotic prescriptions and resistance rates to compare against institutional benchmarks. Furthermore, it was agreed to link the evaluation findings to the national antibiotic stewardship programme, enabling policy and institutional approaches to address frequently misused items, identified during the evaluation. CONCLUSION: This study provides a framework for establishing a qualitative assessment of antimicrobial use for medical institutions at a national level in the Republic of Korea.

Catalyzing Storytelling in Communication Infrastructure Theory: A Study of Local Ethnic Media.

Communication infrastructure theory (CIT) suggests that an ethnic enclave's communication infrastructure (CI) shapes the community's unique social processes that give rise to social determinants of health. A well-integrated CI in ethnic enclaves that includes community-based organizations (CBOs), local ethnic media, and resident networks is positively associated with residents' health outcomes. Through storytelling, CBOs and other community actors obtain and disseminate information, develop a sense of belonging to the community, and participate in problem-solving activities, including health-related ones. Local ethnic media can play an important role in building a network of neighborhood storytellers by catalyzing storytelling about local resources and problems. We propose three main categories of "catalyzing storytelling" by local ethnic media: 1) CBO stories, 2) geo-ethnic stories, and 3) presentation of root causes and solutions for community problems. This study examines the content of Boston Chinatown's local ethnic news media outlet, Sampan, to assess the three categories of catalyzing stories. We analyzed a total of 340 news articles and one interview with the editor. The findings showed that Sampan tells stories in all three categories. Based on our findings, we further develop the concept of catalyzing as a communication process in CIT. This new concept in CIT has practical implications for public health communication as it demonstrates a process through which local ethnic media can foster community engagement and health. Health communicators should seek opportunities to work collaboratively with local ethnic media in ways that will serve to catalyze community.

Current Status and Prospect of Qualitative Assessment of Antibiotics Prescriptions.

Identifying inappropriately prescribed antibiotics for infectious diseases by monitoring the quality of antibiotics use is essential for effective implementation of antibiotic stewardship. Qualitative assessment of the use of antibiotics has been conducted in some countries, including Korea, since the 2000s. The qualitative assessment generally involves an assessment of each component of the antibiotics prescription process, based on specific criteria. However, there is no standardized assessment method or cycle, and infectious diseases or antibiotics included in the assessments vary from country-to-country. According to the results reported in the United States, Europe, Australia, and Korea so far, approximately 20 - 55% of all antibiotics prescriptions are inappropriate. In this review, we describe the current progress in the quality assessment of the use of antibiotics on a global scale. Further, we highlight the future directions to improve antibiotic stewardship activities and the quality assessment of the use of antibiotics in Korea.

Effect of a hospital-wide campaign on COVID-19 vaccination uptake among healthcare workers in the context of raised concerns for life-threatening side effects.

BACKGROUND: All healthcare workers (HCWs) in Yongin Severance Hospital were allocated to receive the ChAdOx1 nCov-19 vaccine according to national policy. A report of thrombosis and thrombocytopenia syndrome (TTS) associated with ChAdOx1 nCoV-19 led to hesitancy about receiving the second dose among HCWs who had received the first dose. METHODS: From 7 to 14 May, 2021, we performed a survey to identify the factors associated with hesitancy about receiving the second vaccine dose among HCWs at the hospital who had received the first dose of the vaccine. Based on survey results, a hospital-wide campaign was implemented on 18 May 2021 to improve vaccine coverage. HCWs who completed the second dose completed a self-administered questionnaire to evaluate the effect of the campaign. FINDINGS: Of 1,171 HCWs who had received the first dose of the vaccine, 71.5% completed the online survey, of whom 3.7% refused to take the second dose and 22.3% showed hesitancy. Hesitancy to receive a second dose was significantly associated with age under 30 years and concerns about TTS, and was less common among those who trusted effectiveness and safety of the vaccine. Among HCWs who received the first dose, 96.2% completed vaccination with the second dose between 27 May and 4 June, 2021. Of those who answered the questionnaire asked about the timing of their decision to receive the second dose, 57.1% reported that they were motivated by the hospital-wide campaign. CONCLUSION: A tailored intervention strategy based on a survey can improve COVID-19 vaccination uptake among HCWs.

Epidemiological investigation and physician awareness regarding the diagnosis and management of Q fever in South Korea, 2011 to 2017.

BACKGROUND: In South Korea, the number of Q fever cases has rapidly increased since 2015. Therefore, this study aimed to characterize the epidemiological and clinical features of Q fever in South Korea between 2011 and 2017. METHODS/PRINCIPAL FINDINGS: We analyzed the epidemiological investigations and reviewed the medical records from all hospitals that had reported at least one case of Q fever from 2011 to 2017. We also conducted an online survey to investigate physicians' awareness regarding how to appropriately diagnose and manage Q fever. The nationwide incidence rate of Q fever was annually 0.07 cases per 100,000 persons. However, there has been a sharp increase in its incidence, reaching up to 0.19 cases per 100,000 persons in 2017. Q fever sporadically occurred across the country, with the highest incidences in Chungbuk (0.53 cases per 100,000 persons per year) and Chungnam (0.27 cases per 100,000 persons per year) areas. Patients with acute Q fever primarily presented with mild illnesses such as hepatitis (64.5%) and isolated febrile illness (24.0%), whereas those with chronic Q fever were likely to undergo surgery (41.2%) and had a high mortality rate (23.5%). Follow-up for 6 months after acute Q fever was performed by 24.0% of the physician respondents, and only 22.3% of them reported that clinical and serological evaluations were required after acute Q fever diagnosis. CONCLUSIONS: Q fever is becoming an endemic disease in the midwestern area of South Korea. Given the clinical severity and mortality of chronic Q fever, physicians should be made aware of appropriate diagnosis and management strategies for Q fever.

Health-related quality of life among migrant workers: The impact of health-promoting behaviors.

Health-related quality of life is an important aspect of migrant workers' overall well-being and adaptation. The aims of this study were to develop a structural model and test the health-related quality of life among migrant workers. A cross-sectional study design was used, and data were collected from 228 migrant workers from China who are currently living in Korea and using the services of free clinics for health issues. The structured questionnaire disseminated for the study was designed to measure health-related quality of life, health-promotion behaviors, barriers, resources, and perceptual factors. Structural equation modeling was used to test the hypotheses. Health-promotion behaviors and self-efficacy have significant positive direct effects on health-related quality of life, and acculturative stress has a significant negative direct effect on health-related quality of life. These findings suggest that certain strategies are needed for developing health-promotion programs aimed at the betterment of migrant workers' health-related quality of life. Specifically, health-promotion behaviors and self-efficacy among migrant workers should be encouraged, and strategies for decreasing their acculturative stress should be formulated.

Novel radiographic parameters for the assessment of total body sagittal alignment in adult spinal deformity patients.

OBJECTIVE: In this study, the authors' goal was to develop and validate novel radiographic parameters that better describe total body sagittal alignment (TBSA). METHODS: One hundred sixty-six consecutive operative spinal deformity patients were evaluated using full-body stereoradiographic imaging. Seven TBSA parameters were measured and then correlated to 6 commonly used spinopelvic measurements. TBSA measures consisted of 4 distance measures relating the cranial center of mass (CCOM) to the sacrum, hips, knees, and ankles, and 3 angular measures relating the CCOM to the hips, knees, and ankles. Furthermore, each TBSA parameter was correlated to patient-reported outcome (PRO) scores using the Oswestry Disability Index (ODI) and Scoliosis Research Society-22 (SRS-22) instruments. Thirty patients were randomly selected for inter- and intraobserver reliability testing of the TBSA parameters using intraclass correlation coefficients (ICCs). RESULTS: All TBSA radiographic parameters demonstrated strong linear correlation with the currently accepted primary measure of sagittal balance, the C7 sagittal vertical axis (r = 0.55-0.96, p < 0.001). Moreover, 5 of 7 TBSA measures correlated strongly with ODI and SRS-22 total scores (r = 0.42-0.51, p < 0.001). Inter- and intraobserver reliability for all TBSA measures was good to excellent (interrater ICC = 0.70-0.98, intrarater ICC = 0.77-1.0). CONCLUSIONS: In spine deformity patients, novel TBSA radiographic parameters correlated well with PROs and with currently utilized spinal sagittal measurements. Inter- and intrarater reliability was high for these novel parameters. This is the first study to propose a reliable method for measuring head-to-toe global spinal alignment.

Pooled nucleic acid testing to identify antiretroviral treatment failure during HIV infection in Seoul, South Korea.

BACKGROUND: There have been various efforts to identify less costly but still accurate methods for monitoring the response to HIV treatment. We evaluated a pooling method to determine if this could improve screening efficiency and reduce costs while maintaining accuracy in Seoul, South Korea. METHODS: We conducted the first prospective study of pooled nucleic acid testing (NAT) using a 5 minipool + algorithm strategy versus individual viral load testing for patients receiving antiretroviral therapy (ART) between November 2011 and August 2012 at an urban hospital in Seoul, South Korea. The viral load assay used has a lower level of detection of 20 HIV RNA copies/ml, and the cost per assay is US$ 136. The 5 minipool +algorithm strategy was applied and 43 pooled samples were evaluated. The relative efficiency and accuracy of the pooled NAT were compared with those of individual testing. RESULTS: Using the individual viral load assay, 15 of 215 (7%) plasma samples had more than 200 HIV RNA copies/ml. The pooled NAT using the 5 minipool + algorithm strategy was applied to 43 pooled samples; 111 tests were needed to test all samples when virologic failure was defined at HIV RNA ≥ 200 copies/ml. Therefore, 104 tests were saved over individual testing, with a relative efficiency of 0.48. When evaluating costs, a total of US$ 14,144 was saved for 215 individual samples during 10 months. The negative predictive value was 99.5% for all samples with HIV RNA ≥ 200 copies/ml. CONCLUSIONS: The pooled NAT with 5 minipool + algorithm strategy seems to be a very promising approach to effectively monitor patients receiving ART and to save resources.

Integrated connection to neighborhood storytelling network, education, and chronic disease knowledge among African Americans and Latinos in Los Angeles.

Combining key ideas from the knowledge-gap hypothesis and communication infrastructure theory, the present study aimed to explain the relations among individuals' education, access to community-based communication resources, and knowledge of chronic diseases (diabetes, hypertension, breast cancer, and prostate cancer) among African Americans and Latinos in Los Angeles. Rather than explore the effect of isolated communication resources, this study explored the effect of an integrated connection to community-based storytellers on chronic disease knowledge. The authors hypothesized that individuals' access to a community-based communication infrastructure for obtaining and sharing information functions as an intervening step in the process where social inequality factors such as education lead to chronic disease knowledge gaps in a local community context. With random samples of African Americans and Latinos in Los Angeles, the authors found that access to community-based communication resources plays a mediating role in the case of breast cancer and diabetes knowledge, but not in hypertension and prostate cancer knowledge. The authors discussed these findings on the basis of communication infrastructure theory and knowledge-gap hypothesis.
