Objective Method Results Conclusions To analyze the factors influencing the increase in the cesarean delivery (CD) rate in South Korea and test the hypothesis on advanced maternal age driving the trend.The present study is a population‐based retrospective observational study utilizing administrative data from the Korean National Health Insurance Service. We analyzed a total 3 416 517 births from 2013 to 2022 covered by the national health insurance. The CD rate and contribution of demographic variables to changes in CD rates were calculated using Das Gupta's decomposition method.The CD rate increased from 37.8% in 2013 to 61.6% in 2022. The decomposition analysis revealed that changes in maternal age structure contributed only 8.7% to the increase in the CD rate. When parity was added to maternal age, the explained proportion increased to 17.8%. When other factors were added to the model, such as multiple births, residential area, and income level, it did not contribute significantly to the increase in the CD rates, accounting for 19.0%, 18.6%, and 18.0%, respectively.According to our analysis, less than one‐fifth of the increase in CD rate was explained by the change in maternal age. The rising CD rate in Korea should not be considered an unavoidable consequence of demographic change. Much more diverse factors, including increased risk of medical lawsuits, changes in childbirth culture, and other health system determinants, may be driving the trend. [ABSTRACT FROM AUTHOR]

This study aims to analyze South Korea's experience during the COVID-19 outbreak through a gendered lens. We briefly introduce the COVID-19 outbreak in Korea, scrutinize gendered vulnerability in contracting the virus, and then analyze the gendered aspects of the pandemic response in two phases: quarantine policy and mitigation policy. The authors elicit four lessons from the analysis. First, gender needs to be mainstreamed at all stages of a public health emergency response. Second, in addition to medical care, all formal and informal care work should be considered as an essential component of health care systems. Third, a people-centered approach in health governance should be prioritized to make women's voices heard at every level. Fourth, medical technology and resources to cope with pandemic should be produced and distributed in an equitable manner, acknowledging differential vulnerability and susceptibility.

Background and Objectives: In this study, we evaluated clinical factors associated with implementing a rehabilitation program for patients with COVID-19-associated acute respiratory distress syndrome (ARDS) requiring mechanical ventilation (MV) during the quarantine period. Materials and Methods: This observational study was conducted in the National Designated Isolated ICU, a dedicated COVID-19 center with 18 beds, from 30 December 2020 to 30 May 2022. One hundred and fifty-four patients (mean age: 67.3 ± 13.4 years; male: 59.7%) were enrolled. The ICU rehabilitation program included early mobilization, chest physiotherapy, and dysphagia treatment. Results: Forty-five patients (29.3%) participated in the rehabilitation program. Multivariate logistic regression identified three significant factors: tracheostomy (odds ratio [OR], 2.796; 95% confidence interval [CI], 1.238–6.316; p = 0.013), body mass index ≥ 25.0 kg/m2 (OR, 2.724; 95% CI, 1.276–5.817; p = 0.010), and extracorporeal membrane oxygenation (OR, 2.931; 95% CI, 1.165–7.377; p = 0.022); patients with all three factors were younger (median 44 vs. 70 years, p < 0.001) and had significantly lower Acute Physiology and Chronic Health Evaluation II scores (median 12 vs. 16, p = 0.002) on the MV day. One-year cumulative mortality rates for patients with 0 to 3 factors were 66.7%, 50.8%, 38.9%, and 15.4%, respectively, with a significant difference among them (log-rank, p < 0.001). Conclusions: Three clinical factors associated with implementing a rehabilitation program during the quarantine period for COVID-19-associated ARDS patients were identified. The program was feasible and beneficial, particularly for younger patients with lower illness severity and fewer comorbidities on the day of MV. [ABSTRACT FROM AUTHOR]

Objective: The aim of the present study was to explore inequalities in antenatal care (ANC) in South Korea. Based on the guidelines of the WHO, we categorized less than eight visits to an obstetrical facility as insufficient ANC. We examined ANC inequalities associated with age, disability, nationality, income, and geographic accessibility. Methods: We extracted delivery event claimed from 2013 to 2022 from the National Health Insurance Service database. By tracing back 270 days from the delivery date, we counted the number of antenatal visits for each childbirth and calculated the proportion of women with insufficient ANC and assessed both absolute and relative inequalities for each population group. The logistic regression analysis for both underuse and overuse of ANC were conducted. Results: Out of 3 416 517 childbirths, 104 109 women (3.0%) had fewer than eight ANC visits. Although the average number of ANC visits reached 18.7 in 2022, significant inequalities persisted across different population groups. The insufficient ANC rate was 28.1% for teenage women, 6.4% for disabled women, 10.7% for non‐Korean women, and 15.2% for dependents of medical aid households. Women with low income and those living in obstetric care underserved areas also exhibited higher ANC insufficiency. From 2021 to 2022, sufficiency in ANC decreased for teenage, disabled, and non‐Korean women, highlighting the effects of the COVID‐19 pandemic. Conclusion: Antenatal care inequalities are evident in South Korea's well‐resourced health system. There is a need for further investigation into these disparities and the qualitative aspects of maternity care services. Synopsis: Despite South Korea's well‐equipped health system, significant antenatal care inequalities exist, necessitating further exploration and qualitative analysis of maternity care gaps.

Background/Objectives: This study explores the impact of QMAC-DST, a rapid, fully automated phenotypic drug susceptibility test (pDST), on the treatment of tuberculosis (TB) patients. Methods: This pre–post comparative study, respectively, included pulmonary TB patients who began TB treatment between 1 December 2020 and 31 October 2021 (pre-period; pDST using the Löwenstein–Jensen (LJ) DST (M-kit DST)) and between 1 November 2021 and 30 September 2022 (post-period; pDST using the QMAC-DST) in five university-affiliated tertiary care hospitals in South Korea. We compared the turnaround times (TATs) of pDSTs and the time to appropriate treatment for patients whose anti-TB drugs were changed based on these tests between the groups. All patients were permitted to use molecular DSTs (mDSTs). Results: A total of 182 patients (135 in the M-kit DST group and 47 in the QMAC-DST group) were included. The median TAT was 36 days for M-kit DST (interquartile range (IQR), 30–39) and 12 days for QMAC-DST (IQR, 9–15), with the latter being significantly shorter (p < 0.001). Of the total patients, 10 (5.5%) changed their anti-TB drugs based on the mDST or pDST results after initiating TB treatment (8 in the M-kit DST group and 2 in the QMAC-DST group). In the M-kit DST group, three (37.5%) patients changed anti-TB drugs based on the pDST results. In the QMAC-DST group, all changes were due to mDST results; therefore, calculating the time to appropriate treatment for patients whose anti-TB drugs were changed based on pDST results was not feasible. In the QMAC-DST group, 46.8% of patients underwent the first-line line probe assay compared to 100.0% in the M-kit DST group (p < 0.001), indicating that rapid QMAC-DST results provide quicker assurance of the ongoing treatment by confirming susceptibility to the current anti-TB drugs. Conclusions: QMAC-DST delivers pDST results more rapidly than LJ-DST, ensuring faster confirmation for the current treatment regimen. [ABSTRACT FROM AUTHOR]

Background This study was performed to evaluate the efficacy of using a thin bronchoscope for the diagnosis of pulmonary tuberculosis (PTB). Methods Between March 2019 and November 2021, we prospectively enrolled participants with suspected PTB whose sputum acid-fast bacilli (AFB) smear and tuberculosis (TB) polymerase chain reaction (PCR) tests were negative or who could not produce self-expectorated sputum. Participants were randomized to a control group (bronchial washing [BW] using a 5.9-mm conventional bronchoscope guided by chest computed tomography) or an investigational group (BW using a 4.0-mm thin bronchoscope under virtual bronchoscopic navigation guidance). The primary outcome was detection of TB in BW fluid, defined as a positive result in the Xpert MTB/RIF assay. The secondary outcomes included AFB smear and Mycobacterium tuberculosis culture positivity, time to treatment initiation, and bronchoscopy-related complications. Results In total, 85 participants were included in the final analysis (43 in the control group and 42 in the investigational group). Twenty-three and 29, respectively, were finally diagnosed with PTB. The TB detection rate in BW fluid was higher in the investigational group (72.4% vs 43.5%, P =.035). Mycobacterium tuberculosis culture positivity was also higher in the investigational group (79.3% vs 52.2%, P =.038). No participants required premature bronchoscopy termination because of complications. Of the participants with PTB, the time to treatment initiation was shorter in the investigational group (median, 2.0 days vs 4.0 days, P =.001). Conclusions BW using a thin bronchoscope increases the TB detection rate in patients with PTB compared to conventional bronchoscopy. Clinical Trials Registration. ȃNCT03802812.

Introduction: Despite increasing numbers of homeless people, less attention has been paid to their mental health, particularly associated with crime victimization. This study sought to examine the association between crime victimization and depressive symptoms, as well as the role of social supports among homeless people in Korea. Methods: Using the 2016 National Survey on Living Conditions of Korean Homeless, we measured crime victimization by its type (physical assault, sexual violence, and robbery/theft/fraud) and depressive symptoms over the past 12 months among 1720 homeless people. Social support, as potential moderators, was defined based on whether the study participants have contacted with family, relatives, and friends, or have resided in facilities. Logistic regression was applied to examine the overall association, and for males and females separately. Results: Female homeless people, compared to male homeless people, tended to be targeted for all types of crime victimization. In the gender-stratified analysis, male victims of sexual violence and female victims of financial crime (i.e. robbery, theft, or fraud) were more likely to have depressive symptoms, after adjusting for covariates. The number of incidents of crime victimization was also associated with depressive symptoms. However, social support did not moderate the association between crime victimization and depressive symptoms for males and females. Conclusion: Crime victimization is detrimental to mental health among homeless people but social support did not moderate the association between crime victimization and mental health.
