The real driver of white lab coats was the hygienist movement.

This is a really compelling read with several historical sources, with a title that can be answered in a single sentence buried deep in the article. I'm a little sad to see such quality writing with a title that could be mistaken for a slop blog post.

Well, you need a hook to get readers to start reading.

And it is an interesting article well worth the time spent reading it, so no harm done.

When I worked in the NHS, our coats were far from white because we used to write on them, in magic marker, things like specimen numbers, doctors and nurses names, phone numbers etc. that we had to deal with queries about. I was always impressed that the laundry managed to get them pristine white again.

Of course this was just us sloppy men - female techs carried useful things like notebooks (paper) and biros.

And nowadays in the NHS you will be hard-pressed to spot a white coat - people wear ordinary clothes, scrubs, or nurses uniforms. At least that's my impression as a recent in-patient.

It's hard to tell whether this is a deliberately trolling statement, a fantastical Walter Mitty style statement, or something else.

Coats weren't white for anyone to write on, and clinical staff didn't routinely write on their clothes.

I wasn't a medic, I was a microbiologist. And I can assure you we did write all over them.

NB: The original post said:

    > "our coats were were from white"

Which appeared to be a typo.

The understanding of the original post was "our coats were white because", which implied the purpose of the coats being white, was to allow them to be written on.

The post was edited to read:

    > "our coats were far from white"

Which has a very different meaning. Still questionable, but changes the context from "it was expected that we would write on our clothes", to "we wrote on our clothes".

Did you write on them because a notebook could cross contaminate while the coats are sterilized safely? Did you wash the markers?

I wonder how people handle this now? With IP68 tablets, you can probably just dunk the whole thing in alcohol.

(Also thanks for sharing such an interesting anecdote)

zabzonk5• 4 months ago

No, after a couple of days (or even halfway through a day) our lab coats were about as contaminated as could be!

I agree with you about the use of tablets in hospitals though. I don't think I ever saw one being sterilised las time I was in hospital for a bit.

Yeah, they were banned in the name of hygiene (sleeve length) not that long ago. 2007 in England & 2014 in Scotland I think.

The BMA has some lingering objection to it from what I understand, but since Covid they're all in scrubs anyway. If they want prestige and distinction from nurses/PAs it would probably make more sense to do differently coloured scrubs, as they do in some US TV shows (but not all; no idea about reality).

They do this at my local hospital at least. There is a plethora of colours for different staff roles. I understand this is not consistent across the whole NHS but in general the principle is mostly followed. eg, see

It depends on the hospital and it might also be regional.

At the hospital I go to in California, green is for surgery and everyone else seems to be in a free for all. I know they reserve dark red for visiting specialists, but the doctors and nurses both wear whatever they want.

What an odd thing to say

The writer is retired and probably in his 70s now, so keep that in mind

As a lab worker, what the hell? Post-its perhaps?

saltcured• 4 months ago

In modern times, as I understand it, there has been a complex trade-off.

The environmental impact of that laundry problem has been reduced but at the cost of 3M Corporation producing trillions of post-it notes that carry such tidbits of information around labs instead.

Never thought about this. The kind of question that sounds trivial until you actually try to answer it

I'm sure the article is broadly correct but in 3 separate academic institutions I've worked for in labs the assigned/monogrammed PPE coats were light blue, light red, and dark blue. Likewise my father in law's corporate research lab coats i've received as castoff gifts have all been light blue or dark blue

At one point, I worked in the labs division of a big internet company, where I was a regular software developer surrounded by people with the title "scientist" (basically, programmer/statisticians with PhDs who were running engagement and revenue experiments on our user base).

In the first group meeting I attended, I jokingly asked why no one was wearing a white coat, but my colleagues didn't get the reference, so my joke fell down with a thud.
