Population aging has generated an increased demand for acute healthcare services in persons aged over 65, who may represent up to half of all patients treated in intensive care units (ICU). However, the number of available ICU beds is limited. Intermediate care units (IntCU) require less human and technical resources, and may represent an interesting alternative to intensive care in the geriatric population. This article describes a 10-year, single centre experience at a geriatrics IntCU in Geneva. We observed a significant reduction in in-hospital mortality after the creation of the IntCU (2000-2001) compared to the 2 years immediately preceding its inception (1998-1999).
