Intra-hospital transport is a frequent procedure in the ICU, involving patients with the highest severity scores. Although some studies estimate the rate of adverse events to be around 33% during intra-hospital transport, including 4% of serious adverse events, the epidemiological data available is small, heterogeneous, and probably subject to methodological bias.

The aim of this study observational prospective observatoinal study is to determine:

• the different practices existing between ICUs ("practice survey")
• the occurrence of adverse events during intra-hospital transport provided by intensive care units (epidemiological study)

This is a multicenter prospective observational study on evaluation of practices between ICUs and to describe the occurence of adverse events during intra-hospital transport provided by ICUs (epidemiological study)
