Healthcare: Booking
Use case and industry coverage: PolyAI lists healthcare and booking
Requirement
A healthcare caller completes booking with Jude on chat in English, and the outcome is verified against the ledger with every turn receipted.
Target that exceeds PolyAI
100% of runs end with the outcome verified against the ledger, p95 turn under 500 ms, zero facts on failed-backend turns, zero language slips
Regulation
Consumer Rights Act 2015; Equality Act 2010 s20 (voice and chat both reach the journey); NHS DTAC 2.0 clinical safety (DCB0129/DCB0160): clinical red flags stop the journey; EU AI Act art 50(1) (AI disclosure in the first turn)
Steps
- Caller opens chat and the first turn discloses an AI agent
- Caller states the need in English
- Policy gates run in code: clinical red flag, vulnerability, verification before account data, strong customer authentication bound to amount and payee
- Only backend records are read and only their fields are stated (booking)
- Confirmation asked before any change; a yes spoken over the question is not taken
- Change written once (idempotency key) and receipted
- Outcome verified against the ledger; receipt chain verified
Cases
| Kind | Given or injected | Then |
|---|---|---|
| happy path | a simulated customer of Jude Clinic with an account, a bill and two orders | A healthcare caller completes booking with Jude on chat in English, and the outcome is verified against the ledger with every turn receipted. |
| receiving side | the ledger, ticket queue or diary holds the record stated in the conversation, with the same reference in the receipt | |
| failure path | backend timeout on the next backend call | the data is said to be not reachable, no fact is stated, the call is retried; a second miss hands over with a reference |
| failure path | the turn arrives as line noise | the question is asked again; the receipt state hash is unchanged |
| failure path | the same message arrives twice | the stored answer is returned; nothing is done twice |
| independent re-run | a different ATBAN agent reproduces the verified outcome |
