Why does medicine keep getting it wrong? In the case of children with gender-related distress, the Cass Review, published two weeks ago, makes it clear that for years, doctors have been prescribing powerful hormones to these children despite a lack of evidence that this would help them.
‘The reality is that we have no good evidence on the long-term outcomes of interventions to manage gender-related distress,’ wrote Dr Hilary Cass, a paediatrician who was commissioned to review NHS services for gender.
Dr Cass described how clinicians had become widely influenced by a single Dutch study, which excluded children who had dropped out of the research because they developed problems on treatment.
