TEAM: Trial of Early Activity and Mobilization
- Conditions
- Critically Ill Adults Ventilated >24 Hours in Intensive Care
- Registration Number
- NCT01674608
- Brief Summary
Patients in the Intensive Care Unit (ICU) traditionally receive bed rest as part of their care. They develop muscle weakness even after only a few days of mechanical ventilation that may prolong their time in ICU and in hospital, but the nature of such weakness is poorly understood.
The weakness that develops in ICU is more substantial than that which would result from bed rest alone and is referred to as ICU acquired weakness (ICUAW). This weakness might be due to the combination of inflammation and immobility. The exact mechanisms leading to the nerve and muscle damage which occurs in critical illness are not yet fully understood and require further investigation. However, it is known that ICUAW has an effect on a patient's ability to breathe without a ventilator, walk and perform simple activities (like washing and toileting) and often results in longer mechanical ventilation time and hence, longer hospital stays than might otherwise be expected. It may also affect a patient's ability to return home after their hospital stay. The recovery period in Australian and New Zealand ICU patients is unknown but a trial from Canada has reported ongoing weakness five years after leaving ICU. Weakness in survivors of intensive care is known to be a substantial problem. It is currently not known whether ICUAW may be avoided or its severity reduced with simple strategies of early exercise in ICU.
There are no data about the level of activity and mobility in critically ill patients in Australian and New Zealand ICUs. These data are urgently required to plan a program of research to test whether increasing the level of mobility and activity in our critically ill patients is safe, feasible and efficacious in terms of reducing the severity of ICUAW and improving patient-centred outcomes. The program of research will first include a study to observe the mobility levels in 25 ICUs across Australia and New Zealand to determine safety, barriers to mobility and what type of activities are undertaken by our patients.
From the observational data we plan to develop a pilot randomised controlled trial of early mobility and activity in intensive care units across Australia and New Zealand. This simple, cost-effective strategy may improve functional ability, decrease time on mechanical ventilation and improve long term outcomes in this patient group. By initiating such a program, ANZ investigators might be able to change future patient outcomes worldwide.

unknown nothing (lying in bed, passive stretches) sitting in bed, active exercises in bed moved to chair (via hoist, slide etc but no standing) sitting over edge of bed standing transferring bed to chair marching on spot (at bedside) walking with assistance of 2 or more people walking with assistance of 1 person walking independently with a gait aid walking independently without a gait aidDosage of the best level of activity Intensive care unit stay (average 7 days) The time spent performing the best level of activity and the number of times it is achieved
Time to standing in ICU Intensive care stay (average 7 days) The number of days in ICU before a patient can stand
- Secondary Outcome Measures
