Effects of the intermediate care unit on the oldest-old general surgical patients: a retrospective, pre- and postintervention study.

Background: Whether the intermediate care unit (IMCU) is beneficial for the oldest-old (aged ≥ 80 years) general surgical patients still remains unknown. We aimed to investigate the impacts of IMCU on the clinical outcomes and cost in this population.

Methods: A retrospective, pre- and postintervention study was performed in this population in a university teaching hospital.
