ClinConnect Summary

This study is looking at how different ways of sharing information about cancer medicines affect what people expect from their treatment. Specifically, it will test whether adding a clear "key information" section to patient leaflets helps people better understand the benefits and possible harms of the medicine. Some leaflets will have no benefit information, some will include general descriptions of benefits, and others will provide both general descriptions and numbers to explain how well the medicine works.

Adults aged 18 and older who live in the UK and speak English are eligible to take part. If you join, you’ll be randomly given one of the three types of leaflets to read online, and the researchers will then see how well you understand the medicine’s benefits and risks. This study hasn’t started recruiting yet, but it aims to help improve the way medicine information is shared, so patients can make better-informed decisions about their treatment.
