In Japan, the response to COVID-19 has been a disaster response. In May 2021, the number of patients requiring hospitalization increased rapidly in Sapporo City, Hokkaido. Almost all medical institutions and clinics were overcrowded, and patients were forced to wait at home. Sapporo City requested a response from the Japan Disaster Medical Assistance Team (DMAT).

DMAT collaborated with the Sapporo City Public Health Center to set up a patient waiting station (The Temporary Medical Facility for Hospitalization Waiting) utilizing an unused hotel. DMAT placed the patient under medical care, provided oxygen therapy and other procedures, and coordinated hospitalization referrals. DMAT also organized a doctor home response system for patients who need emergency hospitalization and those who have returned home from The Hospital Waiting Stations.

64% of the patients were admitted to hospitals, 27% back to their homes, 9% were sent to residential care facilities, and 1% were sent to welfare facilities. The doctor home response system was able to redirect 52% of patients requiring emergency hospitalization.

For the rapidly increasing number of patients with COVID-19, DMAT established a temporary medical facility and home visit system and was able to minimize the number of preventable deaths.
