1 in 7 South Koreans in Clinical Trials

Rise of Patient Groups in South Korea

A recent survey has highlighted the growing presence of patient groups in South Korea, revealing that one in seven individuals is part of such organizations. The findings come from the “2025 South Korea Patient Group Status Survey,” conducted by the Health Insight Center of Enzaim Health, a healthcare PR firm. According to the report, there are currently 902 active domestic patient groups, with over 7.34 million participants—accounting for 14.4% of the country’s total population.

This significant number indicates a shift in how patients engage with their health conditions and seek support. The survey also showed that more than half (51.6%) of these active groups have 1,000 or more members, with 126 groups (15.9%) having over 10,000 members. Additionally, 30 groups (3.8%) boast 50,000 or more participants, highlighting the scale and reach of these organizations.

Common Conditions and Group Sizes

Among the 575 disease-specific patient groups identified, certain conditions dominate the landscape. Diabetes groups were the most prevalent, with 65 registered groups. Cancer-related groups followed closely, with 32 groups dedicated to general cancer awareness and treatment. Breast cancer had 31 groups, while intervertebral disc herniation and Parkinson’s disease each had 31 and 28 groups respectively.

These numbers suggest that chronic and long-term conditions are driving the formation of patient groups. The ability to share experiences, access resources, and receive emotional support plays a key role in the growth of these communities.

Structure and Operations of Patient Groups

The survey also provided insights into the structure and operations of these patient groups. It was found that 88.2% of the groups are unregistered private organizations, indicating a lack of formal recognition or oversight. When categorized by operating entity, individuals formed the majority, accounting for 77.7% of all groups. Organizations or associations made up 8.6%, while hospitals or medical staff contributed 7.8%.

Most of these groups operate on social communities, such as online cafes, where members can connect and share information. The majority (79.1%) adopt a closed operational model, restricting board access to members only. This approach helps protect sensitive patient information and ensures a secure environment for discussions.

Implications and Future Outlook

The increasing number of patient groups reflects a broader trend in South Korean society, where individuals are taking a more active role in managing their health. These groups serve as vital platforms for education, advocacy, and mutual support. As more people become aware of their conditions, the demand for such communities is likely to grow.

However, the informal nature of many of these groups raises questions about their sustainability and effectiveness. While they provide immediate support, there may be a need for greater collaboration with healthcare institutions to ensure that the information shared is accurate and beneficial.

As the healthcare landscape continues to evolve, the role of patient groups will remain an important aspect of public health. Their ability to foster community and provide personalized support makes them a valuable resource for patients and healthcare providers alike.
