Background: Low English language literacy is a common barrier to participation in clinical trials. Patient information leaflets (PILs) used in clinical trials are often lengthy, complex and have poor readability; this is a persistent and prevalent problem common to trials across the world. Simplifying the information provided in PILs can lead to improved understanding, comprehension and knowledge. The aim of this project was to develop recommendations for developing accessible PILs for clinical trials through a literature review of published and grey literature and co-working with marginalised communities, patients, and health and social care charities.

Methods: A literature review of MEDLINE, Embase and online resources was conducted, and recommendations for developing accessible PILs were extracted from eligible published and grey literature. Grey literature which contained insights into more inclusive forms of communication was also identified and summarised. Meetings were held with two racially marginalised community groups, two groups involving autistic adults and/or adults with learning difficulties and a patient advisory group. Examples of accessible PILs were shared and discussions held about the content and format of the PILs and suggestions for changes/improvements. National Voices, a coalition of health and social care charities in England, held a national online workshop with charities and lived experience partners. Recommendations identified from the multiple sources were coded, collated and refined to develop an overarching framework of recommendations.

Results: The framework consists of 74 recommendations for developing accessible PILs for clinical trials. Recommendations cover the five topics of formatting, information presentation, writing style, content and accessibility.

Conclusions: This project has developed a comprehensive framework of recommendations to guide researchers in the development of accessible PILs for clinical trials. Findings from previous research and from co-working with marginalised communities, patients and health and social care charities were collated to ensure that a diverse range of voices and experiences informed the framework. These recommendations aim to support researchers to develop better study information to reduce English language literacy as a barrier to participation in clinical trials.
