Clinical Trial Summary

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

Description:

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 critically injured 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:

1. 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]

2. Limit use of excessive supplemental oxygen

3. Reduce exposure to hyperoxemia without a substantive increase in hypoxemic episodes or adverse effects

Intervention

Other:
• Targeting Normoxemia (SpO2 90-96%; PaO2 60-100 mmHg)
Post-implementation of targeted normoxemia through oxygen titration for individual patients. Interventions 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).
