Organ transplantation is a remarkable medical advancement that saves countless lives, but the demand for organs often exceeds the available supply. In South Korea, the number of patients awaiting organ transplants has been rising steadily, while the number of actual transplants has declined in recent years. One promising solution is the practice of donation after circulatory death (DCD), where organs are retrieved from patients who have been declared dead based on the cessation of circulatory function.
A recent multicenter study in South Korea has shed light on the potential for DCD to address the organ shortage in the country. The researchers found that among 177 patients who died after the withdrawal of life-sustaining treatments, 20 (11.3%) were identified as medically suitable DCD donors. This aligns with findings from other countries, suggesting that DCD can be a viable option for expanding the donor pool.
The study also explored the current practices and perspectives of critical care physicians in South Korea regarding the declaration of circulatory death. The researchers found that while the majority of physicians rely on the absence of a pulse and a flat electrocardiogram (ECG) to determine death, there was some disagreement on the optimal timeframe for this declaration. Notably, only 59.2% of the surveyed physicians agreed with the widely accepted “5-minute no-touch” period for confirming circulatory death, raising the need for further consensus on standardized protocols.
As South Korea continues to grapple with the organ shortage, this study provides valuable insights that could inform the development of comprehensive policies and guidelines for DCD. By establishing clear criteria for declaring circulatory death and streamlining the process, the country can unlock the potential of DCD to save more lives through organ transplantation.
Addressing the Organ Shortage in South Korea
Organ transplantation is a remarkable medical advancement that has transformed the lives of countless individuals suffering from organ failure. However, the persistent imbalance between the demand for organs and the available supply remains a significant challenge worldwide, including in South Korea.
In South Korea, the number of patients awaiting organ transplants has been steadily increasing, reaching nearly 50,000 in recent years. Meanwhile, the actual number of transplanted organs has been declining, and the number of patients who have died while on the waiting list has been rising. This disparity highlights the urgent need to explore alternative sources of organ donation to address the growing demand.
Exploring the Potential of Donation After Circulatory Death
One promising solution is the practice of donation after circulatory death (DCD), where organs are retrieved from patients who have been declared dead based on the cessation of circulatory function, rather than the traditional criteria of brain death. DCD has been gaining traction in various countries, as it can expand the pool of potential donors and help alleviate the organ shortage.
A recent multicenter study conducted in South Korea aimed to investigate the feasibility and current practices of DCD in the country. The researchers focused on patients who had died after the withdrawal of life-sustaining treatments, a scenario known as “category III” under the Modified Maastricht Classification of Donation after Circulatory Death.
Identifying Suitable DCD Donors
The study found that out of the 177 patients who died after the withdrawal of life-sustaining treatments, 20 (11.3%) were identified as medically suitable DCD donors. This proportion is in line with findings from other countries, suggesting that DCD can be a viable option for expanding the donor pool in South Korea.
The researchers also noted that the causes of death among the potential DCD donors were diverse, with organ failure, trauma, hypoxic brain damage, malignancy, and cerebrovascular diseases being the most common. This contrasts with some previous studies, which have reported a higher proportion of patients with hypoxic brain damage, highlighting the potential for DCD to be applicable to a broader range of medical conditions.
Exploring Current Practices and Perspectives on Circulatory Death Declaration
In addition to identifying potential DCD donors, the study also investigated the current practices and perspectives of critical care physicians in South Korea regarding the declaration of circulatory death. The researchers found that the majority of physicians relied on the absence of a palpable pulse and a flat ECG signal to determine death, which is in line with practices in some European countries.
However, the study also revealed a lack of consensus on the optimal timeframe for declaring circulatory death. While 87.5% of the surveyed physicians reported declaring cardiac death immediately or within 5 minutes of a flat ECG signal, only 59.2% agreed with the widely accepted “5-minute no-touch” period for confirming circulatory death.

Towards Standardized Protocols for DCD in South Korea
The findings of this study highlight the need for the development of comprehensive policies and guidelines for DCD in South Korea. Establishing clear and standardized criteria for declaring circulatory death, as well as streamlining the process of organ retrieval, will be crucial for unlocking the full potential of DCD to address the organ shortage.
By addressing the legal and ethical considerations surrounding DCD, and fostering consensus among healthcare professionals, South Korea can pave the way for a more robust and equitable organ donation system. This, in turn, can save more lives through life-saving organ transplants.
Expanding the Donor Pool and Improving Outcomes
The successful implementation of DCD in South Korea could have far-reaching implications. By expanding the pool of potential organ donors, DCD can increase the availability of transplantable organs, reducing the waiting time for patients in need. Additionally, advancements in medical technology and techniques have helped mitigate the challenges associated with organ ischemia, improving the viability and outcomes of DCD transplants.
Towards a Comprehensive Approach to Organ Donation
As South Korea continues to grapple with the organ shortage, the insights from this study underscore the importance of a multifaceted approach to addressing the challenge. In addition to exploring the potential of DCD, the country must also continue to promote awareness and education about organ donation, address any ethical or legal barriers, and foster collaboration among healthcare professionals, policymakers, and the broader community.
By taking a comprehensive and evidence-based approach, South Korea can unlock the full potential of organ donation and transplantation, ultimately saving more lives and improving the quality of life for those in need.
