Evaluation of the Impact of Within-hospital Trajectories of Patients Admitted in Intensive Care Units (ICU) From Emergency Departments

This multicenter cohort aims to assess the impact of within-hospital trajectories of patients admitted in intensive care units from emergency departments on vital prognosis of patients, duration of hospital stay and hospital costs. As secondary objectives, the study will: * assess the impact of clinical and demographic characteristics on hospital trajectories of patients. * assess the impact of emergency units workload, beds availability in medical units and in intensive care units, and global hospital organisation on patients care trajectories.
