Butterfly hatched you "received carefully supervised appropriate treatment, in full knowledge of its experimental nature"
'Experimental' in the sense of, hypothesis, research, proposal, experiment, evidence, conclusion?
If so, I am disappointed for you that you took the risks that you did, and Cass was unable to locate the evidence.
If this experiment were to have high rate of success it would have been career defining for any clincian involved. They would record success and over 30 yrs should be easily placed to publish both quantitative and qualitative data.
You suggested your treatment was carefully supervised and was appropriate. How was it supervised, by whom, how do you now know it was appropriate?
You have a good life now, that's great, but can you be sure that this would not have been the case without this treatment? You are a resilient person who has overcome challenges, but you can never know what your life would be like without this treatment. Perhaps someone in your cohort, with similar degree of distress you had, presented with the same options you were and chose not to take the risk you took. They had an outcome too. They were supported and cared for by the same services. I'd want to know, what was their outcome? Why did the clinicians have no curiosity at all about the range of interventions taken and not taken.
However, if you mean 'experimental' in the sense that clinician/s had an 'I reckon', and conducted the experiment without measurable purpose or evidentiary product. And inexplicably enabled to do so without any oversight or expectation that they maintain records and data.
If that was the case, then I am still glad it worked out for you. That was a risk that you took. However, I can clinicians advocate that anyone else should consider taking the same risk you did in the absence of evidence. Particularly if there was knowledge of other factors which may account for a persons distress.
I fear that the absence of evidence suggests that you were in the minority.
EITHER for some inexplicable reason this experiment was conducted in a distressingly unethical way and NHS gender services omitted to capture any (high or even moderate quality) evidence in this 30 year journey. Which is incredible, is it not?
OR they did indeed capture the evidence and it did not support the hypothesis (and by failing to report findings, they have chosen to bury the evidence). In this case, at some point, the clinicians involved, knew that they were progressing a treatment pathway, in the knowledge there were poor outcomes. And they failed to raise an alarm and prevent future harms associated withthis pathway. Perhaps in time we'll learn why.
There has been a lot invested in promoting affirmation approach in healthcare. Again, perhaps in time we'll better understand why.
I am glad this was successful for you, but you can only speak for you.
