A couple of years ago I did some work around inequalities in
healthcare; the fact that people with mental health problems or learning
disabilities tend to get significantly poorer access to and outcomes from
health services. This was a reaction both to the many examples I’d come across
through working with advocacy organisations and the BMA report that showed that
diagnostic overshadowing (i.e. ascribing
physical health complaints to issues relating to mental health or disability)
contributes to a shortening of life expectancy of between 10 – 15 years.
Sometimes these issues are framed in terms of a shortfall in
the person; that the person can’t speak up or articulate their problems well.
Or that there is an intrinsic interlinking of mental health and physical health
pathology. I’d like to offer an alternative narrative, but to do so I have to
give some additional context.
There was a time when I was able to keep personal and
professional stuff completely separate. Some of you will know that this kind of
ended when I was open about my experiences with depression. In one post I
talked of trying to view my depression as a state from which I was recovering
rather than a one-off incident like a car crash. The comparison wasn’t
arbitrary. I’d recently been in car accident and was sure that the road to
recovery would be swift. Now, almost two years later, I am still dealing with
spinal pain. Though I am a fan of irony it is little compensation for the pain
and the impact that has on my life.
So what does this have to do with anything? Well, a little
while ago after the physio had said I had a clear and consistent problem
relating to a couple of my vertebrae I was sent for an MRI scan. When I phoned
my GP surgery to find out the outcome, the doctor that I spoke to said that the
results were unclear as the image not good enough for diagnosis. No problem
there, such things happen. The next thing they said surprised me, though it
really shouldn’t have. In short it was along these lines (paraphrased for
brevity) :
GP: I see from
your notes that there are references to depression. Are you sure that the pain
isn’t just an expression of that?
Me: I’m pretty
sure. I think it’s more to do with being in a stationary car that was hit from
behind by a car going over 30 mph. The pain started about an hour after the
incident. It hasn’t changed for 2 years. I’m pretty sure that’s the more likely
cause.
GP: But you
might not know how depression can affect the way you perceive pain. Are you
sure it’s not about that?
Me: No, I’m
pretty sure it was the car accident. I know a bit about depression, this isn’t
part of it. By the way, how did you jump from “the image isn’t clear enough for
diagnosis” to “are you sure it’s not in your head?”
GP: Erm…
There’s a wonderful idea in logic called Ockham’s (or Occam’s)
razor. It basically means that if there
are a competing ways of explaining something, you should choose the explanation
that relies on the fewest assumptions. The GP assumed that it was more likely
that I would experience back pain as an expression of depression. I assumed
that it was more likely to be down to being rear ended by a car.
The GP assumed that an unclear MRI scan was down to my
depression. (No, I don’t get it either). I assume it’s more likely to be down
to having to lie on my back for a scan on an injury that is exacerbated by any
pressure being put on my back. I would say that I’d leave it to you decide
which was the more likely explanation, but we’d both know I was lying.
I was able to talk this through with the GP, we got to a
reasonable endpoint. But I absolutely felt as if a health problem with a
definably physical cause (it even had a registration plate for goodness sake) was
being put down to my past mental health. It takes a pretty big assumption to
overshadow a car.
So I’m offering this up as an example. Whether we call it
diagnostic overshadowing or the credibility gap, the problem can’t be located
solely in the person who is disadvantaged in healthcare. It’s not just about
being able to speak up; I can do that. It’s not about a lack of articulacy; I hope
I’ve shown I can manage to string a few words together. It’s not even about
mysterious causes. Cars have not been mysterious since the early 1900s. The
problem is caused by the fact that, regardless of how much it strains Ockham’s razor, too many
people think that mental health problems somehow preclude physical ill health.
