Is this because using them is incredibly slow or something else?
My understanding is that the ~4 measurements the system would use as inputs were typically measured by the doctor, and by the time the doctor had collected the data they had simultaneously come up with their own diagnosis. Typing the observations into the computer to get the same level of accuracy (or a few extra percentage points) rarely seemed worth it, and turning the doctor from a diagnostician to a tech was, to put it lightly, not popular with doctors. :P
There are other arguments which would take a long time to go into. One is "but what about X?", where the linear regression wouldn't take into account some other variable that the human could take into account, and so the human would want an override option. But, as one might expect, the only way for the regression to outperform the human is for the regression to be right more often than not when the two of them disagree, and humans are unfortunately not very good at determining whether or not the case in front of them is a special case where an override will increase accuracy or a normal case where an override will decrease accuracy. Here's probably the best place to start if interested in reading more.

Recursive Heroic Responsibility
Heroic responsibility for average humans under average conditions
I can predict at least one thing that people will say in the comments, because I've heard it hundreds of times–that Swimmer963 is a clear example of someone who should leave nursing, take the meta-level responsibility, and do something higher impact for the usual. Because she's smart. Because she's rational. Whatever.
Fine. This post isn't about me. Whether I like it or not, the concept of heroic responsibility is now a part of my value system, and I probably am going to leave nursing.
But what about the other nurses on my unit, the ones who are competent and motivated and curious and really care? Would familiarity with the concept of heroic responsibility help or hinder them in their work? Honestly, I predict that they would feel alienated, that they would assume I held a low opinion of them (which I don't, and I really don't want them to think that I do), and that they would flinch away and go back to the things that they were doing anyway, the role where they were comfortable–or that, if they did accept it, it would cause them to burn out. So as a consequentialist, I'm not going to tell them.
And yeah, that bothers me. Because I'm not a special snowflake. Because I want to live in a world where rationality helps everyone. Because I feel like the reason they would react that was isn't because of anything about them as people, or because heroic responsibility is a bad thing, but because I'm not able to communicate to them what I mean. Maybe stupid reasons. Still bothers me.
