[MCOH-EH] Color vision testing of healthcare workers

[Robinson, Geoffrey]

I agree with Dr. Sparhawk, who makes a very good point.  (Hi Dana.)  We also use the 14 plate Ishihara as the initial screening tool, for certain positions at our hospital including lab and nursing, as well as DOT.  However, if the employee or driver fails Ishihara we use a secondary testing method.  You can use felt swatches, colored paper, or as we do electrical wires.  I have also seen online color plates with hundreds of colors of varying shades.  I also don't recall ever seeing anyone fail the secondary testing method.

I am in agreement with Dr Upfal.  I myself am red green color blind, cannot read most of the Ishihara plates, but can distinguish between shades and colors very well.  Although we do the 14 plate Ishihara here too, we do not use it to disqualify, but rather to educate the employees with color deficiencies to work with their departments regarding tasks requiring color differentiation.

Personally, I think those of us who fall into this category can differentiate shades on dipsticks, blood tubes, etc very well.  Likewise, in 30 years of doing DOT exams, I don't recall ever finding a driver who could not differentiate the colors.

So how do you use the information?  Does it really predict job performance?  For which jobs?  What if they fail the test but can still perform the job?

We test nursing, laboratory, pathology, and medical staff for color vision with Ishihara 14 plate in our clinics.    We find that some of the hospitals with whom we are now affiliated are using Ishihara 38 plate instead of 14 plate.  What method do you all use?  Is there any evidence that more plates are a better screening tool in this setting?  Thanks for your input.
