Stroke Care Gap: Ambulances and ERs Use Different Severity Scales in South Korea

The Hankyoreh highlights a critical flaw in South Korea's emergency medical system for stroke patients, revealing a dangerous gap between how ambulances and emergency rooms classify patient severity. This bureaucratic lag means that even when a stroke patient is rapidly transported by emergency services, they may face delays in treatment upon arrival at the hospital due to outdated classification systems.

The core issue lies in the delayed revision of the Enforcement Decree of the Emergency Medical Services Act. While medical guidelines, such as the Korean Triage and Acuity Scale (KTAS), have been updated to reflect advancements in stroke treatment—extending the critical window for intervention up to 24 hours—the legal framework has not kept pace. This forces emergency rooms to operate under older standards, potentially downgrading the urgency of stroke patients who would be classified as critical under newer protocols.

As explained by Dr. Ko Sang-bae, a policy director at the Korean Stroke Society, this discrepancy leads to a chaotic situation where a significant portion of stroke patients (estimated at 65%) are classified as less urgent (KTAS-3) in the ER, despite being deemed critical (KTAS-2) by paramedics. This can result in patients waiting for treatment, losing precious time during the 'golden hour' crucial for effective stroke intervention. The Hankyoreh emphasizes that this is not merely an administrative oversight but a matter of life and death for stroke victims.

The article also touches upon the Korean Stroke Society's proposal for a dedicated 'neurology specialist' system in emergency rooms, ensuring constant availability of expert care. The Ministry of Health and Welfare acknowledges the need for reform and promises to expedite the revision process. However, the Hankyoreh implicitly questions the pace of change, given the life-threatening nature of stroke and the persistent delays. This situation underscores a broader challenge in South Korea: ensuring that medical regulations swiftly adapt to evolving medical practices to provide the best possible care for patients, especially in time-sensitive emergencies.
