Whilst I agree that there is a lot of pseudo-science involved in many of these scores and scales, and the clinical community definitely needs to impose more rigour and informatics input, I’m not sure they represent a true patient risk, unless there is an attempt to over-engineer and make assumptions that their individual or computed scores have some kind of real independent biological meaning .
They are (or so we are led to believe) useful compressions of more real-world inputs that guide treatment and decision. I don’t see the use of numerics inside as being inherently risky.
