Family emails and AI confidentiality: what an update after a fall gives away in ChatGPT or Claude.
Writing to a resident’s family is the hardest writing in aged care, because it has to be accurate, kind and careful all at once. That is why staff ask ChatGPT or Claude to help with it. The email carries the resident’s health information, the family’s own circumstances, and whatever difficult thing the service needs to say. This page marks every item in an email to a daughter after her mother’s fall that the Aged Care Act 2024 and the Privacy Act protect, and shows how the same email is drafted on Ermos inside the service.
The email to a resident’s family
Sent by the registered nurse or facility manager to the substitute decision-maker after an incident, a change in condition or a care review.
To: Carolyn Thornbury-Wu1
From: Beatriz Santos, Registered Nurse, Kurrajong Gardens8
Subject: Your mum, this morning
Dear Carolyn,
I wanted to write as well as call, so you have everything in one place.
At about 5.40 this morning your mum was found on the floor beside her bed. The sensor mat had alerted staff and they were with her within two minutes. She had a small cut above her left eyebrow and was complaining of pain in her left hip, the side she broke in 2024.2
Because she takes apixaban, a blood thinner, and hit her head, our protocol is a hospital assessment. The ambulance took her to St Hilda’s at 6.30am. The hospital has rung to say the CT scan of her head is clear and the hip X-ray shows no new fracture. They expect to send her back to us this afternoon.3
I also want to be honest with you about the last fortnight. Your mum has been more distressed in the evenings, and twice she has struck staff during personal care. We have asked Dr Nair to review the risperidone dose, and we need to talk with you about the behaviour support plan, because any change to that medication needs your consent as her guardian.4
Separately, the pressure area on her sacrum has not improved, and we have asked the wound nurse to see her on Thursday.5
I know Peter has been asking the front desk for updates. As you have asked, we have not given him clinical information, and I wanted you to know he called again on Tuesday.6
Could you ring me on (02) 5550 0100 this afternoon? I would also like to arrange a care review with you and Dr Nair next week.7
With kind regards,
Beatriz8

What happens in Frontier Models (ChatGPT, Claude)
- The whole document is transmitted to the provider’s servers. On personal plans the user cannot choose where it is stored or processed, and for the major providers that has generally meant outside Australia, under that country’s legal process. Some business plans offer storage in Australia, but the provider still receives the content.
- On consumer tiers, prompts can be retained and used to train future models.
- The provider’s staff and systems can reach the content under the provider’s own policies.
- Once sent, the service no longer controls it. Retention and deletion happen on the provider’s terms.
The same document on Ermos
Ermos Dominion
The document is drafted on a unit in your office, from your own templates and the resident’s record. Every marked item stays on the unit, which keeps working with the internet switched off. Nothing in it is transmitted to an AI provider, so there is no disclosure to analyse: the confidentiality work is the same as for your file server.
Ermos Edge
Your documents, the index and your access boundaries stay on your own instance in an Australian data centre. When a staff member asks for this draft, only their question and the excerpts they are permitted to see go to a named Australian provider, who is contractually barred from keeping the content or training any model on it. Nothing is processed outside Australia.

| Who can read it | Provider staff and systems, under policy | Your staff, within the boundaries you set. The named Australian provider processes only permitted excerpts, under contract, and keeps nothing | Your staff only |
| Is it kept | On the provider’s terms | Kept on your instance; the provider is barred from retaining it | Stays on the unit |
| Can it train a model | On consumer tiers, yes | No, by contract | Only your own unit learns from it, on your hardware |
