Strategy to Avoid Excessive Oxygen in Major Burn Patients

The objective is to determine the effectiveness of a multimodal educational intervention to reduce supplemental oxygen use in major burn patients. Investigators will also evaluate the safety and clinical effectiveness of the more targeted use of oxygen therapy.

About this study

Oxygen therapy has undisputed importance in the care of critically ill patients to prevent secondary complications related to hypoxemia. Although routine, the practice of excessive over-oxygenation may be harmful. An expert panel was convened and developed the strong consensus to target normoxemia at an oxygen saturation (SpO2) range of 90-96%, an arterial oxygen (PaO2) range of 60-100 mmHg (when applicable), and a fraction of inspired oxygen (FiO2) of 21% for mechanically ventilated patients or room air for nonmechanically ventilated patients.

Specific Aim: The purpose of this study is to determine the effectiveness of a multimodal educational intervention to reduce supplemental oxygen use in major burn patients. Investigators will also evaluate the safety and clinical effectiveness of the more targeted use of oxygen therapy.

Hypotheses: Clinical efforts to through a multimodal educational intervention will:

  • Improve the proportion of time spent within target normoxemia thresholds (oxygen saturation [SpO2] 90-96% and/or arterial oxygen [PaO2] 60-100 mmHg [when applicable])
  • Limiting use of excessive supplemental oxygen
  • Reduce exposure to hyperoxemia without a substantive increase in hypoxemic episodes or adverse effects

Treatment and study plan

Targeting Normoxemia (SpO2 90-96%; PaO2 60-100 mmHg)

Other

Post-implementation of targeted normoxemia through oxygen titration for individual patients. Intervention for treatment of hypoxemia will follow usual local practice. Interventions for treatment of hyperoxemia (SpO2 >96% or PaO2 > 100 mmHg) will involve down titration of FiO2 (or supplemental oxygen for non-mechanically ventilated patients) within a time frame based on local site preferences-typically in increments of no greater than 0.10 until goal oxygenation in the normoxemia range is achieved (including room air [no supplemental oxygen] for non-mechanically ventilated patients).

Primary outcomes

  1. Supplemental Oxygen Free Days (SOFD)

    Time frame: up to 28 days

    Number of days alive and not on supplemental oxygen during the index hospitalization (0 days [worst outcome] to 28 days [best outcome])

Secondary outcomes

  1. Hospital-Free Days to day 90 (HFD90)

    Time frame: up to 90 days

    Number of days alive and outside the hospital (0 days [worst outcome] to 90 days [best outcome])

  2. In-hospital Mortality to day 90

    Time frame: up to 90 days

    Dichotomous vital status (survived or died) at hospital discharge or day 90, whichever is first

  3. Time to Mortality to day 90

    Time frame: up to 90 days

    Vital status and date of death censored at hospital discharge or day 90, whichever is first

  4. Ventilator Free Days (VFD) to day 28

    Time frame: up to 28 days

    Ventilator Free days = Days off ventilator (0 VFD [worst outcome] to 28 VFD [best outcome])

  5. Time to Room air

    Time frame: up to 90 days

    Duration of supplemental oxygen (FiO2 = 0.21 or room air)

  6. Time to Burn Wound Healing

    Time frame: up to 90 days

    Wound closure of >90% of the original burn or time to grafting (for non-full thickness wounds)

  7. Discharge Disposition

    Time frame: up to 90 days

    Defined as home (return to prior level of care) or facility (e.g., acute rehab, skilled nursing facility)

  8. Amount of Supplemental Oxygen Administered

    Time frame: up to 90 days

    Total estimated oxygen volume while in the burn until after hospital arrival

  9. Duration of Time on Normoxemia Protocol Target

    Time frame: up to 90 days

    Defined as SpO2 90-96% or receiving no supplemental oxygen (FiO2 0.21 or room air) while in the burn unit

  10. Proportion of Participants Receiving High Levels of Supplemental Oxygen

    Time frame: up to 90 days

    FiO2>0.40 or >4 liters per minute for >2 hours while in the burn unit [excludes time in the operating room]

  11. Duration of Time Receiving High Levels of Supplemental Oxygen

    Time frame: up to 90 days

    FiO2>0.40 or >4 liters per minute while in the burn unit

  12. Duration of Time Receiving No Supplemental Oxygen

    Time frame: up to 90 days

    FiO2 0.21 or room air while in the burn unit

  13. Incidence of Hypoxemic Event (SpO2<88%)

    Time frame: up to 90 days

    SpO2 saturation below 88% while in the burn unit

  14. Duration of Hypoxemic Events (SpO2<88%)

    Time frame: up to 90 days

    SpO2 saturation below 88% while in the burn unit

  15. Incidence of Hyperoxemic Event (SpO2>96%)

    Time frame: up to 90 days

    SpO2 saturation above 96% while in the burn unit

  16. Duration of Hyperoxemic Event (SpO2>96%)

    Time frame: up to 90 days

    SpO2 saturation above 96% while in the burn unit
