After the randomization process is completed, the person conducting ICU randomization will reveal the allocation of ICUs to other study co-investigators. Immediately following this unblinding, the cluster randomized controlled trial will begin. The two ICUs randomized to receive usual care (ICUs C and D) will not be exposed to an intervention during the trial period. The two ICUs randomized to the intervention group (ICUs A and B) will receive the intervention for the duration of the trial period.
