Description of intervention(s) / exposure
All vasopressor-dependent patients who experienced mobilisation with physiotherapists in the ICU at Canberra hospital will be described in this retrospective study. The time frame studied will be October 1 - December 31 2016. Mobilisation includes all activities which facilitate out-of-bed movement, including sitting on the edge of the bed, sitting in a chair, standing, marching on the spot and standing with the assistance of equipment (eg tilt table or gait harness).

Statistical methods / analysis
Descriptive analyses will be used to best describe the sample in terms of demographics, level of vasopressor support and mobilisation / functional level achieved at time of intervention and at ICU discharge, as well as incidence of adverse events.
Correlational analyses will be used to describe any associations between level of vasopressor support and level of mobilisation achieved, and between level of mobilisation achieved and overall functional level at ICU discharge.

Brief summary
Early rehabilitation of intensive care (ICU) patients is essential to reduce the residual burden of ICU-acquired weakness. While various guidelines have been published regarding safety criteria for mobilizing ICU patients (eg Hodgson et al 2014), there is little clarity regarding the safety of mobilizing patients receiving drugs which support blood pressure (vasopressors).
At Canberra Hospital ICU, we have a well-established routine practice of mobilizing ICU patients (eg Green et al 2016, Leditschke et al 2012, Green et al 2009), including those receiving vasopressors. Note that ‘mobilisation’ can include standing people in a relatively passive way (eg with tilt table equipment) and / or sitting patients over the edge of the bed etc. Thus we can mobilise even sedated and / or delirious patients if required. There is very little data about the relationship between vasopressor dose and mobility level that is achievable in ICU.
We wish to describe our usual practice in detail, including accurate quantification of frequency of mobilisation and corresponding dosage of vasopressors. This information will be useful not just to inform our own future practice, but also to other ICU clinicians around the world who seek more clarity on safety criteria for mobilizing patients in ICU.
This study is a simple retrospective audit of our usual practice which will allow us to describe our mobilisation practices across a 3 month period. All the information required for this study is already collected routinely in the Metavision computer program in ICU, thus this study will not pose any additional burden to patients or staff. It is intended that the results of this study would be published in a reputable critical care journal, as well as presented at scientific meetings.
