Great info. This has been the most confusing to me. I understood that if a patient comes through our trauma unit and is admitted, that you would use the “A” during that entire admission. If the patient is discharged and returns 3 days later for a complication and is readmitted, would you use the “S” for that different admission? I don’t know how physician’s are going to keep this straight. And what is defined as “active treatment”? Once a cast is applied, hardware, medication? Any feedback would be appreciated.
