1. Do not order diagnostic tests at regular intervals (such as every day), but rather in response to specific clinical questions;
My specific clinical question every morning is “how are the patient's chemistries today?” but that's not what the writers had in mind. If you're going to wait for a “clinical” (non-laboratory) question to trigger ordering labs what would that be? Do you wait for the patient to get confused or start having arrhythmias before ordering chemistries?
Hospital medicine had a similar recommendation but it said to stop ordering daily labs on stable patients. I can't argue with that wording but by the time patients are stabilized they're ready for discharge.
