Patient information leaflet / patient information sheet Researchers must provide a patient information leaflet to everyone they invite to take part in a research study, to ensure people can make an informed decision about this. The leaflet explains what taking part will involve and should include details about: • why the research is being done, how long it will last, and what methods will be used • the possible risks and benefits • what taking part will practically involve, for example extra visits to a hospital or a researcher coming to interview someone at home • what interventions are being tested, or what topics an interview will cover • how the researchers will keep participants’ information confidential • what compensation is available to people if they are harmed as a result of taking part in the research • who to contact for further information • how the results will be shared with others.
