AI IN HEALTHCARE
Telehealth Consent Assistant: Prototype and UX Insights
Nina C Hubig, IT:U Linz, Austria
This paper introduces an interactive, privacy-preserving AI-enhanced consent assistant designed to improve patient understanding of legal consent forms in telehealth. By integrating a fine-tuned Large Language Model (LLM) with local context retrieval and a text-to-speech component, the prototype aims to overcome common barriers to telehealth adoption, such as complex legal jargon and accessibility issues.
Executive Impact & Key Findings
Telehealth holds immense promise for expanding healthcare access, yet complex consent processes deter many patients. This research demonstrates how a GDPR-compliant, AI-powered consent assistant can significantly enhance patient comprehension and user experience, thereby accelerating the adoption of vital digital health services. The system prioritizes data sovereignty and accessibility, setting a new standard for ethical AI integration in healthcare.

Enhancing Consent with AI
The study highlights how AI, particularly fine-tuned Large Language Models (LLMs) combined with local context retrieval, can simplify complex legal consent language. This approach ensures greater patient understanding, addressing a critical barrier in telehealth adoption.
By providing on-demand, context-aware explanations, the AI assistant reduces cognitive load and improves perceived ease of use, making the consent process less daunting for patients. The system's ability to operate within GDPR compliance is crucial for sensitive healthcare data.
Designing for Trust: Avatars and Accessibility
The use of an animated 2D avatar significantly improves human-AI interaction, fostering a sense of continuity and empathy. Research indicates that anthropomorphic interfaces enhance patient comprehension and reduce anxiety, encouraging self-disclosure.
A text-to-speech (TTS) component further boosts accessibility, serving users with varying digital literacy levels. The hybrid AI architecture ensures that explanations are accurate and relevant, building patient trust in the digital consent process.
GDPR Compliance & Data Sovereignty
A core tenet of this system is its commitment to privacy. By employing a self-hosted, fine-tuned LLM and local context retrieval, the solution ensures that sensitive patient data remains within a GDPR-compliant environment.
This architecture mitigates risks associated with third-party services, providing a robust framework for secure and ethical AI-enhanced consent in healthcare. Balancing innovation with stringent privacy requirements is paramount for patient trust and broader adoption.
Measuring User Experience and Impact
The study utilized a mixed-methods approach, combining quantitative metrics like SUS (System Usability Scale), NASA-TLX (Task Load Index), and TAM (Technology Acceptance Model) with qualitative feedback.
Results consistently showed that the AI-enhanced system improved perceived usability, reduced cognitive workload, and increased perceived ease of use compared to traditional PDF forms, providing robust evidence for its effectiveness and user acceptance.

Ethical Integration of AI Avatars in Healthcare
The study highlights the critical role of animated 2D avatars in improving human-AI interaction. Anthropomorphic interfaces are shown to enhance patient comprehension, reduce anxiety, and encourage self-disclosure, particularly among users with low health literacy.
However, the research also underscores important ethical considerations, including privacy risks related to sensitive personal health data, the need for transparency, and preserving patient autonomy. The system addresses these by ensuring a GDPR-compliant, privacy-preserving adaptation, emphasizing that AI tools should complement, not replace, human-led consent discussions.
