About this study
Official title: The Relationship Between the Use of a Continuous a Zero-heat Flux Temperature Monitor on Initial Discharge Hypothermia Rate Among Severely Injured Trauma Patients: a Randomized Controlled Trial. (RUZIT Trial)
Hypothermia amongst trauma patients is a persistent problem that increases the relative risk of transfusion as well as morbidity and mortality. The investigators propose to conduct a single-centered randomized controlled trial to determine if the use of a zero-heat flux (ZHF) temperature monitor can reduce the incidence of hypothermia amongst trauma patients discharged from the trauma bay (TB). All eligible trauma patients will be randomized to either a standard of care group or an active temperature monitoring group. In the active temperature monitoring group, a ZHF monitor will be placed on respective trauma patients to continuously record their temperatures after they enter the TB at a large tertiary trauma centre, Sunnybrook Health Sciences Centre (SHSC), in Toronto, ON. The investigators will determine if early continuous temperature monitoring can reduce the incidence of hypothermia upon discharge from the TB. Should early monitoring of severely injured trauma patients within the hospital improves discharge temperature, the foundation for two additional research studies will be laid. Firstly, the investigators will enter a vanguard phase of this trial and assess if early warming patients can improve morbidity and mortality in this patient population utilizing a multi-centered randomized controlled trial design. This will be further extended to test whether early monitoring can be applied in a pre-hospital setting (i.e. within ambulances and transport vehicles) to improve admission temperatures in the TB.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Standard of Care GroupDevice
ZHF temperature monitor cable will be placed appropriately on the forehead by the care team under the direction of the research personnel. The research personnel will then connect this cable to a screen that is blinded to the care team but not to the research personnel.
Active Warming GroupDevice
ZHF temperature monitor cable will be placed appropriately on the forehead by the care team under the direction of the research personnel. The research personnel will then connect this cable to a screen that is un-blinded to everyone so healthcare practitioners will be able to visually detect continuous temperature readings from the ZHF monitor.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Hypothermia amongst trauma patients is a persistent problem that increases the relative risk of transfusion as well as morbidity and mortality. The investigators propose to conduct a single-centered randomized controlled trial to determine if the use of a zero-heat flux (ZHF) temperature monitor can reduce the incidence of hypothermia amongst trauma patients discharged from the trauma bay (TB). All eligible trauma patients will be randomized to either a standard of care group or an active temperature monitoring group. In the active temperature monitoring group, a ZHF monitor will be placed on respective trauma patients to continuously record their temperatures after they enter the TB at a large tertiary trauma centre, Sunnybrook Health Sciences Centre (SHSC), in Toronto, ON. The investigators will determine if early continuous temperature monitoring can reduce the incidence of hypothermia upon discharge from the TB. Should early monitoring of severely injured trauma patients within the hospital improves discharge temperature, the foundation for two additional research studies will be laid. Firstly, the investigators will enter a vanguard phase of this trial and assess if early warming patients can improve morbidity and mortality in this patient population utilizing a multi-centered randomized controlled trial design. This will be further extended to test whether early monitoring can be applied in a pre-hospital setting (i.e. within ambulances and transport vehicles) to improve admission temperatures in the TB.

Questions about this trial
What is this clinical trial studying?
A study testing Active Warming Group in people with Hypothermia and Trauma, run by Dr. Asim Alam at 1 site in Canada.
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 2 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: withdrawn, as of the sponsor's last update on 28 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
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 was withdrawn before enrolling participants, so there are no results.
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?
Hypothermic (<36°C) upon discharge from the trauma bay (time frame: Duration of their stay in the trauma bay or up to 4 hours in the trauma bay (whichever comes first)). 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 NCT03313258, which also lists 16 linked publications.
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 28 Feb 2020.
