Case history/examination
This was a single-center, retrospective, observational case series. An
isolated field hospital for COVID-19 patients was constructed in
Kanagawa prefecture next to Shonan Kamakura General Hospital, which
managed this temporary hospital. The target patients were patients with
and without oxygen demand but were elderly, having underlying disease
that can be considered as risks of COVID-19 including pulmonary disease,
cardiovascular disease, chronic kidney disease, diabetes mellitus, and
others 2 3. Patients requiring intubation were
transferred to other hospitals that were specialized in the treatment of
severely ill patients. Patients who did not wish to undergo intubation
stayed at this hospital.
