Imagine if, for the cost of a single sheet of paper and the effort required to place it in the patient's medical chart, you could reduce length of stay by 2 days and save up to $4600 per patient yet have no impact on readmission rate, 30-day mortality, or patient satisfaction. One might think a deal with the devil had been struck, as public and private insurers, health care systems, hospitals, and individual health care providers would likely pay a fair amount for such an intervention.
