“…Patients and professionals have described informed consent for a trial as an empty ritual in which patients are provided with complex information that is difficult to understand and has little impact on their decision making (Armstrong et al, 2012;Lidz et al, 2004). Although the information provided during elicitation of informed consent has improved (Bjorn et al, 1999;Flory & Emanuel, 2004;Synnot et al, 2014), patients' understanding of consent remains suboptimal, leaving unmet patient needs (Bell & Balneaves, 2015;Brehaut et al, 2012a;Gillies et al, 2014;Moynihan et al, 2012). Previous studies show that patients possess poor knowledge and understanding about key aspects of trial processes and treatments (DixonWoods et al, 2007;Lidz et al, 2004;Pope et al, 2003) and find it difficult to integrate the information with their values and goals (Baker et al, 2013).…”
