Background/Aims: Tracheostomy is a crucial intervention for severe pneumonia patients requiring prolonged mechanical ventilation (MV). However, debate persists regarding the influence of tracheostomy timing and performance on long-term survival outcomes. This study utilized propensity score matching to assess the impact of tracheostomy timing and performance on patient survival outcomes. Methods: A retrospective observational study employing propensity score matching was conducted of respiratory intensive care unit (ICU) patients who underwent prolonged acute MV due to severe pneumonia from 2008 to 2023. The primary outcome was the 90-day cumulative mortality rate, with secondary outcomes including ICU medical resource utilization rates. Results: Out of 1,078 patients, 545 underwent tracheostomy with a median timing of 7 days. The tracheostomy group exhibited lower 90-day cumulative mortality and a higher survival probability (hazard ratio [HR] 0.52, 95% confidence interval [CI] 0.43–0.63) than the no-tracheostomy group. The tracheostomy group had higher ICU medical resource utilization rates and medical expenditures. The early tracheostomy group (≤ 7 days) had lower ICU medical resource utilization rates and medical expenditures than the late tracheostomy group (> 7 days). However, there were no significant differences in the 90-day cumulative mortality rate and survival probability based on tracheostomy timing (HR 0.94, 95% CI 0.70–1.28). Conclusions Tracheostomy in patients with severe pneumonia requiring prolonged MV significantly reduced the 90-day mortality rate, and early tracheostomy may offer additional benefits for resource utilization efficiency. These findings underscore the importance of considering tracheostomy timing in optimizing patient outcomes and healthcare resource allocation.

OBJECTIVES: Geographic disparities in access to secondary pediatric care remain a significant issue in countries with universal health coverage, including Korea. This study investigated the link between geographic access to secondary pediatric care and mortality rates in children and adolescents (0-19 years) in Korea. METHODS: We analyzed district-level data to assess the percentage of those aged 0-19 years residing outside of a 60-minute travel radius from the nearest secondary pediatric care provider (accessibility vulnerability index, AVI). RESULTS: The AVI ranged from 0% to 100% across the districts for the study period. The confidence interval (CI) was -0.30 (95% CI, -0.41 to -0.19) in 2017 and -0.41 (95% CI, -0.52 to -0.30) in 2021, indicating that the proportion of those who could not access care within 60 minutes was disproportionately higher in districts with lower socioeconomic status. We found 8% rise in mortality rates among individuals aged 0-19 years for every 10% increase in AVI (95% CI, 1.06 to 1.10). CONCLUSIONS The study highlights disparities in pediatric care access and their impact on child survival, emphasizing the need for improved access to achieve true universal health coverage.

In cases where pulmonary tuberculosis (PTB) is not microbiologically diagnosed via sputum specimens, bronchoscopy has been the conventional method to enhance diagnostic rates. Although the additional benefit of bronchoscopy in diagnosing PTB is well-known, its overall effectiveness remains suboptimal. This review introduces several strategies for improving PTB diagnosis via bronchoscopy. First, it discusses how bronchoalveolar lavage or an increased number of bronchial washings can increase specimen abundance. Second, it explores how thin or ultrathin bronchoscopes can achieve specimen acquisition closer to tuberculosis (TB) lesions. Third, it highlights the importance of conducting more sensitive TB-polymerase chain reaction tests on bronchoscopic specimens, including the Xpert MTB/RIF assay and the Xpert MTB/RIF Ultra assay. Finally, it surveys the implementation of endobronchial ultrasound with a guide sheath for tuberculomas, collection of post-bronchoscopy sputum, and reduced use of lidocaine for local anesthesia. A strategic combination of these approaches may enhance the diagnostic rates in PTB patients undergoing bronchoscopy.

Background: With the epidemiological transition, sociodemographic changes and differential lifetime experiences of women, women’s health research improves knowledge of diverse health issues and the impact of policies. To explore the initiatives of women’s health research in Korea, the present study examined the trends and topics of research on women’s health funded by the government. Methods: We searched all research projects on women’s health funded by the government between 2012 and 2020 in Korea using the National Science & Technology Information Service database. We reviewed all the titles and abstract of the projects and examined the research trends by year. Content analysis was performed using both deductive and inductive approaches. Text network analysis and visualization by topic were conducted for keywords with a minimum of 10 occurrences in the title and abstract. Results: Total number and funding amount of research projects on women’s health in 2020 increased by 2.4 and 2.2 times over 2012 levels, respectively. The Ministry of Health and Welfare and the Ministry of Food and Drug Safety funded 20.9% of all projects. The majority of the topics (59.8%) addressed breast and gynecological cancers. Those on sexual and reproductive health accounted for 16.7%, with steep growth in the number (6.1 times) and funding (11.1 times) over 2012 levels. The topic analysis presented a more complex keyword network in 2020 than in 2012; however, the keywords frequently used in 2020 were similar to those of 2012. Conclusion Women’s health research projects have been growing in number and funding, with limited diversity in topics. Diversifying the topics and focusing on issues beyond the breast and pregnancy would be needed to reflect the complete life course of women.Institutionalization of diverse communication channels with various interest groups for women’s health would be needed to better understand women’s health needs from a public health perspective.
