Factor in also that if the psychiatrist got it wrong, there would have to have been collusion from other doctors dealing with her in the mental hospital, and from the obstetricians.
No collusion necessary. Consultant psychiatrist is 'God' within his team - no junior would dare challange if they wanted a continuing career in their manager's NHS department. Obs definitely would not challange a psych decision - not their specialism they so they follow the psych. In our case the Consultant Paediatrician, Gp, Ed Pysch, La etc were all prepared to accept the original (mis)diagnosis. All should have realised that a (mis)dx of very serious mental illness was unsafe as it was given after a mere 5 minute 'interview' with a non communicative patient.
But no, they all fell in behind the Consultant Pyschiatrist. Once the correct dx had been secured (by me), the sheep all fell into place behind that new psychiatric decision.
So new, in my experience, no 'collusion' is necessary for a bad opinion to stand - just ineptitude, deviation from due process, apathy, secrecy, refusal to challenge fellow professionals etc.
I was once one of those people who automatically trusted all the professionals my family would be involved with were competent and acting in our interests. Very disillushioned to see first-hand how the system actually works.
I never thought that my Ex and I would be sitting down one afternoon considering whether to flee with our children to Ireland or Spain following a disasterous meeting with Consultant Psychiatrist who threatened to section our DS based on his blatent misdiagnosis.
Can you begin to imagine how terrifying that situation was?
I sincerely hope you never have to have dealings with these people. You may find that everything in the garden is not quite as rosy as you currently believe it to me.
