AI-written plain-language discharge summaries for people with blood and other cancers

Prospective Randomized Controlled Trial to Evaluate Locally Implemented Large Language Models (LLMs) for Simplifying Patient Communication in Hematology and Oncology

Not applicable Interventional Technical University of Munich · NCT07519811

This project tests whether AI-written plain-language discharge letters help adults with hematologic or other cancers understand their diagnosis, treatment, and next steps better than the usual medical letter.

What this trial studies

This single-center, prospective randomized controlled trial at the Technical University of Munich randomizes hematology and oncology inpatients 2:1 to receive an AI-simplified discharge letter plus the standard letter or the standard letter alone. An on-premise large language model automatically simplifies key sections of the discharge letter and a study physician reviews and approves the simplified text before patient delivery. Patients with limited German proficiency are enrolled in a separate, nonrandomized translation arm where letters are simplified and translated. The primary outcome is a 5-item Likert-based comprehension score with questionnaires completed after patients read their letters.

Who should consider this trial

Good fit: Adult inpatients of the Department of Medicine III (Hematology/Oncology) at Klinikum rechts der Isar who receive a routine discharge letter containing the specified sections and are able to give informed consent.

Not a fit: Patients with significant cognitive impairment, those whose discharge letters lack the targeted sections, or people unable to read the simplified language may not gain benefit from the intervention.

Why it matters

Potential benefit: If successful, patients could better understand their care plans and follow-up instructions, which may improve adherence and reduce post-discharge confusion.

How similar studies have performed: Prior technical and observational work shows LLMs can produce accurate plain-language medical summaries, but randomized trials testing clinical benefit in oncology discharge care are lacking.
