Study summary

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.

Study arms

  • Active comparator
    Standard of Care Group

    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.

    Device: Standard of Care Group

  • Experimental
    Active Warming Group

    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.

What researchers measure

Primary outcomes

  1. Hypothermic (<36°C) upon discharge from the trauma bay

    Proportion of patients who are 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)

Secondary outcomes

  1. Warming initiatives

    Total number of warming initiatives implemented by trauma care team

    Time frame: Duration of their stay in the trauma bay or up to 4 hours in the trauma bay (whichever comes first)

  2. Transfused products

    Number of transfused blood products

    Time frame: Duration of their stay in the trauma bay or up to 4 hours in the trauma bay (whichever comes first)

  3. Length of stay

    Number of days patient stayed in hospital

    Time frame: Time of admission to discharge or up to 1 year after admission (whichever comes first)

  4. 30 day mortality

    Alive or deceased at 30 day

    Time frame: Time of admission to discharge or up to 30 days after admission (whichever comes first)
