Description of intervention(s) / exposure
Prospective evaluation of clinical decision making in critically ill patients.
Prospectively evaluate all the factors that influence clinical decision making of when to commence early rehabilitation in intensive care units. These factors will be identified through an extensive literature review and consultation with international experts who have published in the area of early rehabilitation in critically ill patients. Doctors, Nurses and Physiotherapists will be asked if the patient in front of them is ready to complete early mobilisation. If the therapist responds "No" they will then be asked to rank the factors that have influenced their decision. The duration of clinician involvement will be the time it takes to come to their decision each day. The participant who the decision is being made about will remain in the study for duration of their ICU stay or until 3 consecutive days of rehab occur.

Control group

Primary outcome [1] 298509 0
Prospective evaluation of the factors that influence a clinician's decision to commence early rehabilitation in ICU utilising a specifically designed data collection tool created following an extensive literature review and international expert consultation to identify potential influential factors..
Timepoint [1] 298509 0
Daily ICU consultation for 20 days or until three consecutive days of rehabilitation occur.
Secondary outcome [1] 325750 0
Describe the early rehabilitation (duration, highest function level, personnel and equipment) completed by observed patients
Timepoint [1] 325750 0
Rehabilitation completed in ICU until three consecutive days of rehabilitation occur.

Key inclusion criteria
Observed Patient inclusion criteria
Predicted to be mechanically ventilated for greater 48 hours.
Predicted intensive care unit length of stay greater than or equal to 48 hours (as per ICU consultant prediction)

Medical, Nursing and Physiotherapist inclusion criteria
Any healthcare provider involved in decision making must hold tertiary degree (or equivalent) in area of practice.
Minimum age
18 Years
Maximum age
No limit
Both males and females
Can healthy volunteers participate?
Key exclusion criteria
Observed Patient exclusion criteria
Known primary systemic neuromuscular disease or intracranial process on admission (as this limits the patient's ability to complete early rehabilitation and alters the clinican's decision making process).

Doctors, Nurses and Physiotherapists exclusion criteria.

Statistical methods / analysis
Following discussion with the team statistician, Leonid Churilov and a senior ICU clinicians, the use of three different decision makers and twelve outcome variables, 1420 observations were required to allow sufficient splitting of nodes in a classification and regression analysis as the splitting of nodes ceases when the node arrived at is relatively homogeneous in relation to the outcome variable, or contains too few observations. One thousand four hundred and twenty observations will mean cessation at a node is dependent on node homogeneity relating to the variable rather than a consequence of too few observations. No formal power calculation was performed.

Descriptive statistics using frequencies and percentages will be used for categorical data. For continuous data mean and standard deviation or median and inter-quartile range for non-parametric data will be recorded. Weighted Kappas, Student t-tests and Mann-Whitney U tests will be used to determine differences between groups for continuous variables. Pearson chi square test of independence will be used to analyse the difference between categorical data. Alpha will be set at p<0.05

Classification and regression tree (CART) analysis to determine the best discriminating variables to predict whether a patient was ready to commenced early rehab

Brief summary
Survivors of the intensive care unit (ICU) can suffer long standing impairments in physical function. Rehabilitation provided in the ICU has been shown to improve physical function outcomes at both hospital discharge and 12-months. Early rehabilitation has been shown to be safe and feasible and may help prevent the long term sequelae. However, early rehabilitation is not routinely implemented in ICU due to cultural barriers and a lack of well-defined safety parameters, it currently relies on the discretion of the clinicians caring for the patient. Clinician's decisions can be influenced by conventional wisdom, personal experience, intuition and knowledge. The factors that clinicians consider to be important in the decision to provide rehabilitation, particularly out of bed functional activities in the ICU, are currently unknown. Therefore we aim to identify the factors that influence the initiation of early rehabilitation and develop a decision making support tree that includes safety parameters to assist clinicians in the provision of early rehabilitation for patients in ICU.
