Strategy A+C, Wedge 1 (ICU #1)
3 months of usual care followed by 6 months with Strategy A alone (a nudge embedded in the order panel including pre-specified settings for mechanical ventilation including tidal volume of 6 milliliters per kilogram predicted body weight \[cc/kg PBW\]that can be opted out of by the ordering clinician at any time with a click), followed by 18 months with Strategy A+C (strategy A as above combined with nudge that requires that the RT enter an explicit rationale in the EHR if he/she enters a tidal volume value greater than 6.5 cc/kg PBW into the flowsheet).
Strategy B+C, Wedge 1 (ICU #2)
3 months of usual care followed by 6 months with Strategy B alone (a nudge embedded in the order panel requiring a free-text justification if a tidal volume greater than 6.5 cc/kg PBW is ordered), followed by 18 months with Strategy B+C (strategy B as above combined with nudge that requires that the RT enter an explicit rationale in the EHR if he/she enters a tidal volume value greater than 6.5 cc/kg PBW into the flowsheet).

Default Order Set
n=956 Participants
This arm will have the default order set implementation strategy Default order set: 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 cc/kg of the patient's ideal body weight (as determined by each patient's height and gender, which are entered into the EHR on admission). The physician will have the option to opt out of any of the specified LPV settings and select other values.
Physician-targeted Accountable Justification
n=734 Participants
This arm will have the physician-targeted accountable justification implementation strategy Physician-targeted accountable justification: When a physician enters a mechanical ventilation order for a tidal volume that is greater than 6 cc/kg ideal body weight, 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.

The physician will have the option to opt out of any of the specified LPV settings and select other values. RT-targeted accountable justification: This strategy will require that the RT enter an explicit rationale in the EHR if he/she enters a tidal volume value greater than 6 cc/kg into the flowsheet, similar to the physician-targeted accountable justification strategy.

SECONDARY outcome

Timeframe: from initiation to discontinuation of mechanical ventilation in the study ICU, up to 720 hours (30 days)

Total duration of exposure to tidal volume greater than 8 cc/kg PBW, in hours. The time frame for follow-up is based on the total duration of IMV during the total follow-up period of 30 days. Note it is intentionally different from the time frame of the primary outcome variable, which focuses on the initial 72 hours, as the period most likely to be influenced by the study interventions.

Total duration of exposure to tidal volume greater than 10 cc/kg PBW, in hours. The time frame for follow-up is based on the total duration of IMV during the total follow-up period of 30 days. Note it is intentionally different from the time frame of the primary outcome variable, which focuses on the initial 72 hours, as the period most likely to be influenced by the study interventions.

SECONDARY outcome

Timeframe: up to 72 hours, from the initiation to the discontinuation of mechanical ventilation in the ICU

The percentage of time during the first 72 hours of mechanical ventilation that patients were alive, in the ICU, and with Richmond Agitation-Sedation Scale (RASS) of -3 to -5 . The RASS measures a patient's depth of sedation and ranges from -5 (comatose) to +4 (combative), with a normal level of 0 (defined as "alert and calm"). Negative values indicate a patient is sedated and positive values indicate some degree of agitation.

SECONDARY outcome

Timeframe: Up to 72 hours, from initiation to discontinuation of mechanical ventilation in a study ICU

Average Richmond Agitation-Sedation Scale (RASS) value, weighted by duration of time at that value. The RASS measures a patient's depth of sedation and ranges from -5 (comatose) to +4 (combative), with a normal level of 0 (defined as "alert and calm"). Negative values indicate a patient is sedated and positive values indicate some degree of agitation.

Binary variable for whether a patient had Richmond Agitation-Sedation Scale (RASS) score of -3 to -5 for the entirety of the first 72 hours of mechanical ventilation. The RASS measures a patient's depth of sedation and ranges from -5 (comatose) to +4 (combative), with a normal level of 0 (defined as "alert and calm").
