About this study

This study aims to describe the pattern of active and sedentary time in survivors of a critical illness, at three time points during their hospital admission (awakening in the ICU after ≥ 5 days of mechanical ventilation, discharge to ward and discharge from hospital).

The specific research objectives are to

  1. Determine the duration of active and sedentary parameters including time and bouts in 24 hour periods
  2. Examine changes in the active and sedentary parameters including time and bouts between time points of awakening and both ICU and hospital discharge.
  3. Conduct a preliminary examination of relationships between activity and sedentary behaviour metrics with measures of muscle strength, physical function and hospital length of stay.
Read the detailed description

This is a prospective observational study that consecutively samples eligible patients with a critical illness, requiring intensive care. This study will use two activity monitors (accelerometers) to measure physical activity and sedentary variables from patients recovering from a critical illness in a single tertiary hospital on three occasions during their acute hospital admission. Accelerometer derived measures will be obtained from continuous 24 hour monitoring periods once patients are sufficiently awake and attentive within the ICU, at ICU discharge and again at acute hospital discharge. Measurements of patients muscle strength and physical function will also be made at the time of accelerometry.

Questions about this trial

What is this clinical trial studying?

An observational study of Motor Activity and Sedentary Lifestyle, run by University of South Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Physical activity time (time frame: Change between events (each event assessed over 24 hours): From closest to the date of awakening in ICU (after at least 5 days of mechanical ventilation, assessed up to 4 months) to closest to the date of ICU discharge (assessed up to 6 months)). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02881801, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Aug 2016.
