Providing the world’s highest standard of medical services in a completely closed ICU system

The department provides multimodality and cross-sectional systematic control and medical care services to all patients with severe diseases from a diagnostic, therapeutic and nursing aspect.

Medical Care System

Our ICU has a completely closed system(12 beds)and semi-closed system(8 beds), in which doctors are exclusively stationed in the ICU for 24 hours under the direction of anesthesiologists and intensive care specialists. They hold conferences in the morning and the evening and provide medical care around the clock with support from specialized clinical departments. The nursing staff ratio is one to two nurses per two patients.

Target Diseases

The department implements systemic controls, such as artificial respiration control, circulatory management, infection control, and nutrition management; after highly invasive cardiac surgery, great vessel surgery, abdominal surgery, and any other major surgical operations; or for patients with multi-organ disorders and severe infections.


Among hospitals affiliated with national university medical schools, a completely closed ICU system is rare, and we achieve the highest level of medical care. Doctors, Nurses, Pharmacists and Clinical Engineers work to improve safety management and service quality and promote advanced medicine.

Clinical Results

In 2021, we received 1,593 patients and the death rate was 4.08%. In 2020, SMR (Standardized Mortality Ratio) is 0.24 (APACHEⅡ) and 0.31 (APACHEⅢ) We actively accept severely-ill surgical outpatients and inpatients.

Other Undertakings

The department aims to provide medical services compliant with world standards. By introducing Evidence-Based Medicine (EBM), we eliminate ad hoc medical services. In addition, working closely with the Emergency and Medical Intensive Care Unit, we are developing therapies for refractory diseases as a university hospital ICU.
