There are two very separate issues at the heart of this.
A) The pregnant woman is entitled to absolute confidentiality and needs to have complete confidence in that confidentiality so that she can disclose her relevant medical and social history. That history, used as part of a holistic assessment should inform discussions about her care and treatment and any additional support she may need. That need for confidentiality, is why women should be seen separately from their partners so that they can safely disclose previous pregnancies their DH/DP may be unaware of.
B) It is useful to have relevant medical details recorded as part of the child health record, and yes it would be convenient to automatically transfer those records. Yes too, the data could inform longitudinal studies. But - and it’s a very big BUT - convenience doesn’t override confidentiality.
There are a lot of scenarios where the medical history of a close family member can inform an assessment, yet there are rightly no proposals to share the records of an adult sibling who had an anaesthetic reaction.
In the state’s attempts to have comprehensive data about its citizens, their rights as individuals are overridden. Now obviously, this starts with pregnant women who are merely empty vessels who need to be controlled,
but at the risk of sounding like a conspiracy nut, it won’t end there.
And the immediate danger, is that in order to protect themselves from the consequences of B, women will choose not to disclose important and relevant information and that will make it more difficult to provide care for them. Still, only women eh?
