Department of Emergency Medicine

As a 475-bed acute care hospital, Yao Tokushukai General Hospital receives approximately 12,000 ambulance arrivals annually, primarily from the Nakakawachi area. Guided by our philosophy, “All living beings are created equal,” we maintain a 24-hour emergency care system and strive to provide care without turning patients away. As of March 2026, the hospital operates 20 ICU beds, 30 HCU beds, and 26 beds designated for patients with infectious diseases.

Our Department of Emergency Medicine serves as the primary point of contact for patients with acute conditions referred by neighboring healthcare facilities through the Hospital–Clinic Liaison Office. We provide prompt initial assessment and treatment.

At night, physicians from Emergency Medicine, Internal Medicine, Surgery, Orthopedic Surgery, Neurosurgery, and Cardiovascular Surgery are on duty to diagnose and treat emergency patients. Dedicated hotlines are also available for suspected stroke and cardiovascular emergencies.

The Hospital Paramedic Unit was established in fiscal year 2026. Hospital-based paramedics support clinical care and emergency response as members of the multidisciplinary team and assist with interfacility transfers using the hospital’s ambulance.

Yao Tokushukai General Hospital has been accredited as a core training institution for emergency medicine specialists and has accepted residents in emergency medicine since fiscal year 2023.
