So you're seriously suggesting that every doctors surgery in the country, when given a change of phone number, should check their records to ensure that the number is changed in all corresponding family members files? Ever heard of patient confidentiality for one...
No. That is not quite what I am suggesting.
...how would they have time to do that anyway?
Is that a serious question?
Here's one example of how efficiency can be accomplished:
Mum contacts them to make an appointment for herself and to give her new number.
Receptionist asks if there are any dependent children or other dependent individuals in her household also registered with the GP and if yes, asks for names.
Receptionist confirms that new contact details apply to all the other named individuals in the household.
It takes maybe five minutes in total.
Far better to spend five minutes getting this accomplished than risk wasting appointment slots, right?
Of course a properly set up file system would have the responsible adult cross referenced with the dependents in the first place. Again, take the time to do this and you can avoid wasting appointments, wasting money on reminder letters that can't be delivered, etc. Or silly situations where the receptionist phones and asks to speak to the 6 month old baby.
Your misunderstanding of 'confidentiality' means you are suggesting that the GP practice should only talk to individual children when appointments are being booked, or only ask a child or toddler to verify contact information at a visit.
