Implementation of Nudges to Promote Utilization of Low Tidal Volume Ventilation (INPUT) Study

With the default order set strategy, some mechanical ventilation order settings will be pre-populated to be consistent with LPV, including the mode and tidal volume, automatically calculated as 6 milliliters per kilogram of predicted body weight (cc/kg PBW; as determined by each patient's height and gender). The physician will have the option to opt out of any of the specified LPV settings and select other values.

When a physician enters a mechanical ventilation order for a tidal volume that is greater than 6 cc/kg PBW, an alert will appear requiring the physician to enter a reason for choosing a setting inconsistent with LPV. Clinicians will be instructed to provide a reason for deviation from LPV settings and that their response will be maintained in the medical record. The physician will not be able to sign the mechanical ventilation order set until after a response is entered.

If an RT enters a tidal volume in a flowsheet documentation field value greater than 6 cc/kg PBW, an alert will appear requiring them to enter a reason for entering a setting inconsistent with LPV. Clinicians will be instructed to provide a reason for deviation from LPV settings and that their response will be maintained in the medical record. The RT will not be able to save the documentation in the EHR until after a response is entered.
