Hospital-Oriented Care Models Face challenges

The question, Are you afraid to go to the hospital?
highlights the complexities of healthcare access. In 1989,South Korea established a national medical insurance system,lauded for its accessibility and affordability. During the 2020 coronavirus pandemic, the World Health Organization (WHO) and international media recognized it as a model for systematic defense and medical response. However, with South Korea becoming an aging society in 2025, with more than 20% of its population over 65, the existing health insurance system faces significant limitations. Medical experts suggest the current system is reaching a disaster level.
The increasing number of elderly patients frequently enough leads to over-treatment and redundant care, raising concerns about the suitability of the current demand-based system. A basic issue lies in the fee-for-service model, where medical institutions generate revenue for each treatment. This incentivizes hospitals to recommend unnecessary tests and procedures to attract more patients. As the elderly population grows, the demand for medical services rises, rapidly depleting health insurance funds.

According to the Korea Health Insurance Corporation, health insurance costs reached approximately 110.8 trillion won in 2023, a 4.7% increase from the previous year.Medical expenses for those 65 and older, representing 18.4% of the total population, accounted for 49 trillion won, or 44.1% of total medical expenditures.
Management of chronic diseases in elderly people with disabilities is an essential medical service, but the current system lacks a thorough structure,
said a professor of family medicine.

South Korea’s medical system is primarily hospital-centric. current medical laws restrict medical practitioners to performing procedures within hospitals, effectively limiting in-home care. This hospital-oriented model struggles to address the growing needs for chronic disease management, long-term care, and community-based services required by the increasing elderly population.

Hospital-Oriented Care Models Face Challenges
The Challenges of Healthcare in an Aging Society
The question, “Are you afraid to go to the hospital?” highlights the complexities of healthcare access. As populations age, healthcare systems face increasing pressures. this article explores the strain aging populations place on health insurance systems, focusing on the issues and potential solutions.
Why is an Aging population a Concern for Health Insurance?
An aging population significantly impacts health insurance systems by increasing demand and costs. The rise in the elderly population leads to a surge in medical needs, primarily due to a greater prevalence of chronic conditions and comorbidities, requiring more intensive care.
how Does an Aging Population Affect Healthcare Costs?
As the elderly population grows, the demand for medical services rises, rapidly depleting health insurance funds. The korea Health Insurance Corporation reported that in 2023, medical expenses for those 65 and older accounted for 44.1% of total medical expenditures.
What is Driving Up Healthcare Costs in Aging Societies?
Multiple factors contribute to rising healthcare costs. These include:
- Increased Demand: The elderly population typically requires more frequent and intensive medical interventions.
- Fee-for-Service Model: This model incentivizes medical institutions to generate revenue for each treatment, which can lead to unnecessary tests and procedures.

South Korea’s Experience with an Aging Population
How Has South Korea’s Healthcare System Been Affected by an Aging Population?
South Korea’s national medical insurance system, established in 1989, was lauded for its accessibility. However, as of 2025, with over 20% of its population over 65, the system faces notable limitations, even to the point where medical experts suggest the system is reaching a “disaster level.”.
What are the Shortcomings of South Korea’s Healthcare Model?
South Korea’s existing health insurance system is strained by the growing needs of its aging population. The hospital-centric model,where medical practitioners are restricted to performing procedures within hospitals,struggles to address the need for:
- Chronic Disease Management: Comprehensive care for long-term conditions.
- Long-Term Care: Facilities and services for extended care needs.
- Community-Based Services: Support provided within local communities to keep people self-reliant.
A professor of family medicine noted, “Management of chronic diseases in elderly people with disabilities is an essential medical service, but the current system lacks a thorough structure.”
