Examination of Personalized SpO2 Targets

Sponsor: Vanderbilt University Medical Center

Summary

Mechanical ventilation involves titrating the fraction of inspired oxygen to maintain arterial oxygen saturation (SpO2). The SpO2 target that results in the best outcomes for critically ill adults has historically been unknown. Randomized trials comparing use of a higher SpO2 target (96-100%) vs a lower SpO2 target (88-92%) have not found an average treatment effect among patients overall. However, the optimal SpO2 target may differ for patients with different characteristics. Recently, data from randomized trials of SpO2 targets were used to derive and validate a statistical model that predicts which SpO2 target will result in the best outcomes for an individual patient based on his or her unique characteristics (personalized SpO2 target). This statistical model has been incorporated into the electronic health record at Vanderbilt such that, for each patient receiving mechanical ventilation in the medical intensive care unit, information on which SpO2 target is predicted to result in the best outcome for the patient can be made available to clinicians. However, the use of personalized SpO2 targets for critically ill adults receiving mechanical ventilation has never been examined in a randomized trial and whether using such a personalized SpO2 target in clinical care can improve patient outcomes remains unknown. This randomized trial will examine the effect of using information on the SpO2 target that is predicted to be best for a patient based on his or her unique characteristics (personalized SpO2 target) versus usual care.
