Enhancing Readability of Lay Abstracts and Summaries for Medical Knowledge Using Generative Artificial Intelligence (BRIDGE AI 3)

4 de maio de 2026 atualizado por: Giovanni Cacciamani, University of Southern California

Enhancing Readability of Lay Abstracts and Summaries for Medical Knowledge Using Generative Artificial Intelligence: A Randomized Controlled Trial (BRIDGE AI 3)

This trial tests if AI can help make medical info clear and readable. Many patients struggle to find medical informations that easy to read and understand from verified medical sources. The study tests if an AI tool can assist health providers to craft clear text for patients more fast than what they do now. Health providers are split at random into two groups-one uses the AI tool and one does not. The trial tests how clear the text is, how correct it is, and how much time is saved. The aim is to see if AI can close the gap between complex research and what patients can grasp.

Visão geral do estudo

Descrição detalhada

This study evaluates whether a generative artificial intelligence (AI) tool can improve the readability and accessibility of lay summaries derived from scientific medical abstracts. Many patients encounter difficulty understanding medical literature due to technical language and complexity, which can limit informed decision-making and engagement with healthcare information.

The BRIDGE-AI (Provider Perspective) initiative aims to address this gap by enabling healthcare professionals and researchers to generate patient-friendly summaries of scientific content using AI-assisted tools. The intervention leverages a generative AI framework (pub2people) designed to translate complex medical terminology into language that is understandable to a general audience.

In this randomized controlled study, participants with experience in scientific publishing will be assigned to either an AI-assisted group or a control group using conventional methods. Participants will be asked to transform scientific abstracts into layperson-friendly summaries. The study compares AI-assisted and manually generated outputs in terms of readability, accuracy, and efficiency.

The primary objective is to determine whether AI-assisted generation improves the readability of lay summaries compared to standard approaches. Secondary objectives include evaluating the accuracy of AI-generated summaries relative to source material and assessing potential time savings associated with AI use.

This study contributes to ongoing efforts to improve health communication by evaluating scalable tools that may enhance the translation of complex medical information into patient-accessible formats.
