Abstract
Introduction Advances in cancer care depend on clinical trials (CTs), yet the number of adults enrolled is suboptimal. Early-phase CTs are complex and particularly difficult to discuss as participants mainly have advanced cancer and are unlikely to receive any therapeutic benefit. Limited health literacy can also be a barrier to participation.1 Our aim was to develop a pictorial encounter decision aid (pEDA)2 to facilitate general and neutral discussions about CT enrolment.
Methods A multidisciplinary, participatory group involving patient partners and other stakeholders drafted a first version of the pEDA. Its acceptability was assessed in interviews with a convenience sample of patients and healthcare professionals. An online survey, including the HLS19-Q12 health literacy questionnaire, was distributed to Seintinelles members (a French national non-profit organization facilitating recruitment for cancer studies).
Results In 2023, 989 complete surveys were collected among participants without cancer (69.8%) or at least one year after ending their active treatment (30.2%). Most of them were women (95.6%) with adequate health literacy (64.3%) who had never heard of early-phase CTs (62.3%).
The mean recommendation of the pEDA was 8.1/10. It was considered easy to understand (98.1%), of suitable length (90.2%) and neutral (66.4%). Health literacy was significantly but poorly correlated with understanding (Spearman’s ρ=0.12) and recommendation (ρ=0.09) of the pEDA, not with perceived neutrality or length of the document. Respondents gave many suggestions (n=2353) for improving the pEDA (content and pictorial design). The two most important sections of the pEDA were the presentation of early CTs, and of risks and side effects.
Discussion A coproduced pEDA was well received, even among low-literate patients. The large sample size obtained provided a broad (but feminine) view of the document and many valuable comments.
Conclusion After new revisions, the coproduced pEDA should be tested to confirm it can facilitate discussions about early-phase CTs.
