Background: Despite the growing necessity for government-led policy changes on clinical research ethics during pandemic, the scope of previous literature is limited to Korean government’s pandemic response strategies or reflections of research ethics at the level of institutions and academic societies. This paper examines the proactive policy changes and responses by the South Korean government in addressing the challenges and issues of research ethics against the backdrop of the urgency of rapid development and emergency supply of medical products during the coronavirus disease 2019 (COVID-19) pandemic. Methods: We conducted searches of various government documents, using predetermined keywords related to research ethics and integrity during the COVID-19 pandemic. Only documents issued by governments or public institutions were included. A total of 24 documents were selected for analysis. They were divided into two phases: the first phase for urgent response (January 2020–February 2021) and the second phase (March 2021–February 2023) for long-term preparedness. Results: The Korean government recommended several measures of research governance to accelerate the ethical review of COVID-related research to be shortened less than one week:the joint operation of Institutional Review Boards (IRBs), exempted or expedited review by a special review committee, guidelines for urgent reviews, and designation of the Korean Academy of Medical Sciences as the supervising agency for the Clinical Trial Safety Support Institution as well as the Central IRB. It allowed temporary non-face-to-face methods for informed consent process (telephone explanations and a photo of the original signed consent) and clinical trials (telephone counselling and prescription, proxy prescription, and drug delivery and supply to clinical trial participants, and online ethics training). Conclusion As a result of South Korea’s commitment to ethical principles in their pandemic response, the medical system did not experience collapses due to the pandemic, and pandemic research was conducted with careful ethical considerations. The pandemic ethics immunization during the Middle East respiratory syndrome epidemic in 2015 laid the foundation for prompt government initiatives that ensured both pandemic research ethics and pandemic response ethics.

Background: Healthy life expectancy is a well-recognized indicator for establishing health policy goals used in Korea’s Health Plan. This study aimed to explore Koreans’ healthy life expectancy and its gender, income, and regional disparities from 2008 to 2020. Methods: This study was conducted on the entire population covered by health insurance and medical aid program in Korea. The incidence-based “years lived with disability” for 260 disease groups by gender, income level, and region was calculated employing the methodology developed in the Korean National Burden of Disease Study, and it was used as the number of healthy years lost to calculate health-adjusted life expectancy (HALE). Results: Koreans’ HALE increased from 68.89 years in 2008 to 71.82 years in 2020. Although the gender disparity in HALE had been decreasing, it increased to 4.55 years in 2020. As of 2020, 5.90 years out of 8.67 years of the income disparity (Q5–Q1) in HALE were due to the disparity between Q1 and Q2, the low-income groups. Income and regional disparities in HALE exhibited an increasing trend, and these disparities were higher in men than in women. Conclusion A subgroup with a low health level was identified through the HALE results, and it was confirmed that improving the health level of this population can reduce health inequalities and improve health at the national level. Further exploration of the HALE calculation methodology may help in the development of effective policies such as prioritizing interventions for health risk factors.

Background: The measurement of health levels and monitoring of characteristics and trends among populations and subgroups are essential for informing evidence-based policy decisions.This study aimed to examine the burden of disease in Korea for both the total population and subgroups in 2020, as well as analyze changes in disease burden from 2008 to 2020. Methods: We employed the methodology developed in the Korean National Burden of Disease and Injuries Study to calculate disability-adjusted life years (DALYs) by sex, causes, region, and income level from 2008 to 2020. DALYs were derived by combining years of life lost and years lived with disability. Results: In 2020, the burden of disease for the Korean population was estimated to be 25,439 DALYs per 100,000 population, reflecting a 13.8% increase since 2008. The leading causes of DALYs were diabetes mellitus, followed by low back pain and ischemic stroke. A sex-specific gap reversal was observed, with the disease burden for men surpassing that of women starting in 2017. Furthermore, variations in disease burden were identified across 250 regions and income quintiles. Conclusion It is imperative to establish appropriate health policies that prioritize the diseases with significantly increasing burdens and subgroups experiencing high disease burdens. The findings of this study are expected to serve as a foundation for developing healthcare policies aimed at improving the health levels of Koreans and achieving health equity.

Background: Health-adjusted life expectancy (HALE) is an indicator of the average lifespan in good health. Through this study, we aimed to identify regional disparities in the gap between HALE and life expectancy, considering the trends that have changed over time in Korea. Methods: We employed a group-based multi-trajectory modeling approach to capture trends in the gap between HALE and life expectancy at the regional level from 2008 to 2019. HALE was calculated using incidence-based “years lived with disability.” This methodology was also employed in the Korean National Burden of Disease Study. Results: Based on five different information criteria, the most fitted number of trajectory groups was seven, with at least 11 regions in each group. Among the seven groups, one had an exceptionally large gap between HALE and life expectancy compared to that of the others.This group was assigned to 17 regions, of which six were metropolitan cities. Conclusion Based on the results of this study, we identified regions in which health levels have deteriorated over time, particularly within specific areas of metropolitan cities. These findings can be used to design comprehensive policy interventions for community health promotion and urban regeneration projects in the future.

Purpose: With the revision of the Organ and Transplantation Act in 2018, the hand has become legal as an area of transplantable organs in Korea. In January 2021, the first hand allotransplantation since legalization was successfully performed, and we have performed a total of three successful hand transplantation since then. By comparing and incorporating our experiences, this study aimed to provide a comprehensive reconstructive solution for hand amputation in Korea. Materials and Methods: Recipients were selected through a structured preoperative evaluation, and hand transplantations were performed at the distal forearm level. Postoperatively, patients were treated with three-drug immunosuppressive regimen, and functional outcomes were monitored. Results: The hand transplantations were performed without intraoperative complications. All patients had partial skin necrosis and underwent additional surgical procedures in 2 months after transplantation. After additional operations, no further severe complications were observed. Also, patients developed acute rejection within 3 months of surgery, but all resolved within 2 weeks after steroid pulse therapy. Motor and sensory function improved dramatically, and patients were very satisfied with the appearance and function of their transplanted hands. Conclusion Hand transplantation is a viable reconstructive option, and patients have shown positive functional and psychological outcomes. Although this study has limitations, such as the small number of patients and short follow-up period, we should focus on continued recovery of hand function, and be careful not to develop side effects from immunosuppressive drugs. Through the present study, we will continue to strive for a bright future regarding hand transplantation in Korea.
