Is ChatGPT GDPR-compliant for medical practices?

Without additional safeguards, using ChatGPT in medical practices is problematic because personal patient data is transferred to servers in the USA. KI-Shield solves this problem by automatically detecting and pseudonymizing all personal data before the request is sent to the AI.

Does this violate medical confidentiality?

If patient data is transmitted unencrypted to AI providers like OpenAI, this may violate Section 203 Criminal Code and medical confidentiality. KI-Shield automatically pseudonymizes all personal data before it leaves your practice.

What does KI-Shield cost for my practice?

The Free plan is permanently free. All prices and details can be found at ki-shield.eu/pricing

Do I need to modify my software?

No. KI-Shield works as a proxy between your practice and the AI. You only change the API URL in your existing software. Alternatively, use the integrated chat interface directly in your browser – no installation required.

The Risk

The Risk für Ihre Praxis

Every unprotected AI request can become a liability trap.

Health Data at US Providers

Diagnoses, lab values, and medication plans at OpenAI or Google – a clear violation of Section 203 Criminal Code. The medical board may revoke your license to practice.

Insurance Data in Plain Text

Insurance numbers, ICD codes, and treatment histories on US servers – GDPR Art. 9 prohibits processing health data without explicit consent or legal basis.

Liability Risk for Practice Owners

GDPR fines up to EUR 20 million, professional proceedings at the medical board, and civil damage claims from affected patients – personal liability falls on the practice owner.

4,15 Mrd.€ GDPR fines
across the EU since 2018

Leverage the productivity benefits of modern AI – without risk.

Discharge Letters & Epicrises

Dictate findings, AI drafts the discharge letter. Patient name, insurance number, and diagnoses are automatically pseudonymized – the finished letter contains the original data again.

Drug Interactions

Check drug interactions in polypharmacy via AI. The active ingredient list is sent pseudonymized to the AI – no inference about the patient is possible.

Billing Verification (CPT/ICD)

Let AI verify that your billing codes are correctly documented. Patient data stays in the practice – only anonymized billing data reaches the AI.

Report Summaries

Summarize extensive lab and imaging reports in patient-friendly language. Ideal for informed consent discussions – without sharing sensitive data with third parties.

FAQ

Frequently Asked Questions from Medical Practices

No – not without safeguards. Health data falls under GDPR Art. 9 (special categories) and requires additional protection. KI-Shield acts as a proxy between your practice software and the AI: All patient data is automatically pseudonymized before sending. The AI only receives anonymous placeholders – the response is then translated back.

Yes, if patient data is sent in plain text to ChatGPT or similar services. Section 203 Criminal Code protects the doctor-patient relationship under criminal law. KI-Shield ensures that no patient name, diagnosis, or insurance number ever leaves your infrastructure unprotected.

All data is processed exclusively on German servers (Hetzner). No US Cloud Act, no FISA 702. The original data never leaves the proxy server in the EU. Additionally, KI-Shield uses a zero-knowledge architecture: Even the operator cannot read your data – everything is AES-256 encrypted.

The Free plan is permanently free (50 requests/month). All prices and plan details can be found on our pricing page.

No. Simply use the integrated chat in your browser – no installation, plugin, or training effort. If your PMS or HIS already has an AI interface, you just swap the API URL. Your workflows remain unchanged, as does your daily practice routine.
