I think this is exactly the case for automation to be useful without negatively impacting the professional. It’s not a matter of nurses having the knowledge or expertise, but a tool that takes away the toil of monitoring - which is boring, easily skipped or performed badly by a tired brain, and is trivially interpretable. If a thingamabob beeps louder and makes the nurse pay attention to the blood cell count, the human is still in the loop of decision making.
Yes, but also a nurse has bazillion other things to do. That’s probably why, as the CBC journalist reports, “the nursing team usually checked blood work around noon”. So even though it costs a second to do, it’s done was done once a day. Now it’s done continuously because it’s an alert system instead of something the nurse has keep an eye on.
Sure, there’s another computation step. But that’s cheap. Nurse time is the bottleneck. From the POV of a nursing team, before, there was a step (check blood pressure at noon), now there are no steps. They replaced a process of checking some numbers with an automated metric-based alarm. This is textbook operations process optimization, great for everyone involved.
