A useful privacy discussion starts with a journey: what information leaves the practice, which service receives it, what the service does with it and what remains afterwards? A vague promise of security is difficult to assess. A clear data-flow description gives the practice something concrete to review.
The 30-second answer
Identify every data input, recipient and retention point.
Resolve the applicable legal basis and health-data condition before processing.
Assess whether the proposed use requires a DPIA and document the decision.
Health data requires more than one legal question
ICO guidance explains that processing special-category data requires both an Article 6 lawful basis and an applicable Article 9 condition. Dental health information can fall within this category. A supplier's statement that its system is secure does not itself identify either requirement for the practice's use.
Consent to treatment, an explanation of AI use and a data-protection lawful basis are distinct issues. Work out how each applies to the particular service. This article provides questions for review, not a determination of the appropriate legal basis for an individual practice.
Draw the data journey before the demo
Stage | Ask the supplier |
|---|---|
Capture | What audio, images, identifiers or metadata are collected? |
Transfer | Where are they sent, and through which providers? |
Processing | Who acts as controller or processor for each activity? |
Retention | What is stored, for how long and in whose account? |
Secondary use | Can data train models or support another purpose? |
Exit | How are exports, deletion and backups handled? |
Ask for written answers that match the product configuration you will use. A feature that is optional in marketing material may be enabled by default. Likewise, a retention period for one component may not describe transcription files, diagnostic logs or backups.

When does a DPIA enter the process?
The ICO says a DPIA is required for processing likely to result in high risk. Innovative technology, including AI, can be relevant when combined with other risk criteria, such as sensitive information. This is a contextual assessment; it is not a claim that every use of the word AI automatically requires a DPIA.
Complete the assessment early enough to influence the choice and configuration of the system. If it identifies a problem, the useful outcome is a change to the proposed processing, not simply a completed form filed after deployment.
A privacy-ready pilot
Use synthetic or appropriately authorised test material for initial demonstrations.
Check staff permissions and avoid shared access that obscures responsibility.
Resolve supplier terms, relevant subprocessors and any international transfers.
Set a retention and deletion process that matches the actual data flow.
Prepare a clear patient explanation and a route for questions.
Agree how incidents and unexpected disclosures will be handled.
These are original operational prompts. They do not certify compliance or replace advice on a particular processing arrangement. A practice may need its data-protection adviser to resolve uncertain roles, conditions or contractual details.
Do not paste clinical records into an unchecked chatbot
Before sending information to any service, establish that the service and the intended use have been approved through the practice's process. Text can contain identifiers within the narrative, and images can carry embedded details. Removing a heading or a patient name may leave the person identifiable.
Privacy review also differs from reviewing the clinical output. A service can have acceptable data handling while producing a wrong answer, and a useful answer can come from an unsuitable data flow. Both questions need attention.
Frequently asked questions
Does a UK server location settle the whole issue? No. Examine access, recipients, secondary uses, terms and the relevant processing arrangements as well as storage location.
Is anonymisation the same as removing a name? No. Assess whether the remaining information could still identify someone; do not assume a superficial edit is sufficient.
What should be ready before live use? A documented data flow, resolved governance questions, agreed configuration and a process the team can actually follow.
Can this article confirm that our chosen supplier is compliant? No. The answer depends on the product, contracts, configuration and your intended processing.
