I think it's more like Sam's condition did not clearly fit into a checklistable entity. Our heart rate and temperature go up when we have the flu, but we don't all go in to hospital for antibiotics or die at home. Probably they should have done more work-up the second time he came in but as the article points out that could also have been negative. He was probably just too young for checklists built for older people to pick up on his condition.

Also sounds like he was left alone which does not help either. I had similar to Sam, in early sepsis but none of markers were there until I went delirious. Wife picked up on it right away and that time, ER picked up on it.
