Layperson-Friendly AI Translation of Medical Documents to Improve Doctor-Patient Communication: Protocols for the AI-INFOCARE and AI-MEDTALK Randomized Controlled Trials.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMany patients struggle to understand referral letters and discharge summaries; low health literacy is prevalent, and short consultations limit explanations. Large language models (LLMs) can translate clinical jargon into layperson language, but their impact on doctor-patient communication in real care remains untested.
objectiveThis study aims to determine whether providing an artificial intelligence (AI)-generated, medically validated layperson-language translation of key medical documents before a consultation improves the quality of doctor-patient communication.
methodsWe plan to conduct two single-center, parallel-group randomized controlled trials in neurosurgery: AI-INFOCARE (outpatients prior to treatment discussions) and AI-MEDTALK (inpatients at surgical discharge). Adults (aged 18 years or older, German-speaking, and able to consent) are randomized 1:1 to receive either (1) an AI-generated layperson-friendly summary of their referral or discharge document in addition to usual care or (2) usual care only. Summaries are produced with a Claude-based system (Simply Onno GmbH) and undergo human verification against the source document using a predefined checklist. The primary outcome is patient-rated interaction quality (Fragebogen zur Arzt-Patient-Interaktion/Questionnaire on the Quality of Physician-Patient Interaction) immediately postconsultation. Secondary outcomes are perceived autonomy support (brief Health Care Climate Questionnaire), self-rated understanding (5-point item), physician-rated encounter difficulty (Difficult Doctor-Patient Relationship Questionnaire, 10-item), and consultation length (minutes). Randomization uses a computer-generated allocation list with concealed, sequential assignment at the point of inclusion; recruiting clinicians have no access to the sequence, and analysts are blinded to group codes. Fidelity is assured by standard operating procedures, rater training, and periodic dual review with interrater agreement estimates. Safety monitoring defines information-related adverse events (eg, distress requiring unplanned clinical support or clinically relevant inaccuracies) and includes an independent safety overseer. Ethics approvals were obtained in February 2025 from the ethics committee of Technische Universität Dresden, and both trials are registered in the German Clinical Trials Register.
resultsEach trial targets 300 participants (150 per arm), providing greater than 80% power for an effect size d≈0.4 on the primary outcome (α=0.05). Outcomes are assessed immediately after the index consultation, with no additional follow-up planned in this protocol. We hypothesize that providing layperson-friendly summaries will significantly improve patients' understanding and satisfaction with information, foster a more autonomy-supportive communication climate, and reduce physicians' perceived difficulty in the encounter without unduly prolonging consultation time. Neither study received external funding. Both trials are currently in the recruitment phase, with patient enrollment scheduled to begin in May 2025 and expected to conclude by February 2026. Results are anticipated to be published in summer 2026.
conclusionsThese pragmatic randomized controlled trials test a scalable AI intervention to strengthen understanding and interaction quality without adding clinician burden. If effective, AI-assisted layperson summaries could be integrated into routine workflows to advance health literacy and patient-centered care.
