  Objectives: This study aimed to examine the demographic characteristics, chronic disease prevalence, and cardiac arrest-related factors of patients with out-of-hospital cardiac arrest (OHCA) in the Republic of Korea (ROK), and to estimate their long-term survival rates.
  Methods: We analyzed linkage data from the Sudden Cardiac Arrest Survey (SCAS) with National Health Insurance Service (NHIS) claims data. The study population comprised patients whose data were successfully linked between SCAS and NHIS from 2011 to 2021. The demographic characteristics, prevalence of chronic diseases, and cardiac arrest-related characteristics of these patients were analyzed. The 30-day, 1-year, 3-year, and 5-year survival rates of the linked patients were calculated for each year.
  Results: Among the patients with OHCA who had completed investigations during the study period, 95.3% were successfully linked to the NHIS database. The number of linked patients with OHCA increased over time, with an increasing proportion of patients aged ≥60 years. Patients with OHCA had a high prevalence of hypertension, diabetes, chronic pulmonary disease, and heart failure. The standardized 1-year survival rate increased from 3.5% in 2011 to 6.7% in 2019, followed by a slight decline to 6.3% in 2021 after the coronavirus disease 2019 pandemic. The 3-year and 5-year survival rates also increased over time.
  Conclusions: The number of long-term survivors and survival rates of patients with sudden cardiac arrest in ROK continue to increase, and there is a systematic need for continued care and support for these patients.

  Objectives: This study highlights the role and significance of the Masan National Tuberculosis Hospital (MNTH), Republic of Korea’s (ROK) first specialized tuberculosis (TB) hospital, by analyzing its 84-year history and key achievements in the context of the National Tuberculosis Control Program.
  Methods: A literature review and analysis of internal reports and documents related to the MNTH’s history and operations were conducted.
  Results: The MNTH has focused on managing socioeconomically vulnerable TB patients, including those with multidrug-resistant TB (MDR-TB), the elderly, foreigners, and nonadherent patients. With a specialized medical team and standardized treatment, the MNTH has achieved treatment success rates over 10 percentage points higher than the national average. Through integrated nursing care for severely ill patients, has managed to reduce caregiver burden and economic costs. Additionally, it plays a crucial role in preventing TB transmission through isolation and Directly Observed Treatment, Short-course for nonadherent patients. Leveraging its unique TB specimen bank and biosafety level 3 research facility, the MNTH has made significant contributions to TB research and the development of new diagnostic and therapeutic methods. It also participates in national TB control initiatives, including the “TB Safety Belt” project and regional TB prevention efforts. The MNTH is expanding its role to include national infectious disease response.
  Conclusions: The MNTH is expected to enhance its expertise in MDR-TB treatment, underserved TB patient management, and diagnostic and therapeutic development. Expanding its function as a national infectious disease institution will contribute significantly to ROK’s TB elimination goals and enhance national disease response capabilities.
