If you employ a few hundred nurses, how exactly would you evaluate how well they show empathy? You can't rely on asking the customer. When they're upset (they often are in these calls), they'll lean towards the negative regardless. I don't know how well these AIs evaluate, but if they're even a little bit good, it makes sense to use it to screen for outliers, then have a human listen to those outliers and judge.
There's a great academic book called "Stupid Rules". Excessive rules (or KPIs - often rules in disguise) exist because we don't like authority. Get the doctor to assess the nurse. Or the head nurses if you don't trust doctors. The nurses have managers, and if none of the doctors or head nurses can be trusted with a simple matter like assessing whether nurses are doing their jobs then you got bigger issues. Oh no, the…
But evaluating tone and empathy? Great, now every nurse is gonna be wasting their time and energy making sure to recite the best canned, optimized text-adventure incantations for the KPI every time they enter the room instead of using their brains to see what the patient actually needs.
