They had multiple X-rays that they purposefully disregarded and then completely ignored their patient's pleas that he had special medical needs.
To be fair, I think that's a reference to the first Pertwee story. From what I can remember, the doctors in the hospital that take care of Pertwee dismiss the x-Ray as a double exposure, and are baffled by a sample of his blood (it's too sticky or something). Then again I could be remembering that bit from the novelisation by Terrance Dicks, which my dad would read to me when I was little.
Still doesn't excuse the Doctors in the 1996 special from being woefully incompetent though.
