Support persons' preferences for the type of consultation and the format of information provided when making a cancer treatment decision

Objective: Cancer patients and their support persons commonly feel overwhelmed when being confronted with their diagnosis and treatment options. We used a DCE to examine patients' and support persons' preferences for: (i) attending one 40 min consultation or two 20 min consultations when making a cancer treatment decision; and for (ii) receiving additional information in written form only or in both written and online forms. Here we focus on support persons' preferences and whether they differ from patients' preferences. Results: 159 adult medical oncology patients and 64 of their support persons took part in this study. Participants were presented with a set of hypothetical scenarios and asked to indicate their most and least preferred scenario. 92% of support persons (n = 59) completed the DCE. Most preferred to receive two consultations along with written and online information (n = 30, 51%). This was the only scenario that was chosen by statistically significantly more support persons (p =0.037). The proportions of patients and support persons choosing each scenario did not differ significantly from each other (p >0.05). Our findings suggest that when making cancer treatment decisions, clinicians should consider offering patients and support persons written and online information, combined with two shorter consultations.
