Background: Informed consent documents educate patients and families about research participation and alternatives. However, given their length and complexity, consent documents can be challenging to understand, particularly in high-stress environments such as the Intensive Care Unit (ICU) and for complex study designs such as platform trials.
Methods: This is an exploratory sequential mixed methods study-within-a-trial (SWAT) of REMAP-CAP (Randomized, Embedded, Multifactorial, Adaptive Platform Trial for Community-Acquired Pneumonia). Phase 1: We conducted focus groups with individuals with lived experience, including ICU survivors, substitute decision makers (SDMs) and research coordinators (RCs) to refine an infographic to augment a priori REMAP-CAP consent encounters. We analyzed data using inductive content analysis. Phase 2: We piloted the infographic with patients/SDMs approached a priori to participate in REMAP-CAP, who could communicate in English, at five sites in Ontario, Canada. We assessed implementation according to 1) eligible consent encounters (number of patients/SDMs eligible for SWAT / approached for REMAP-CAP), 2) receipt of infographic (number of patients/SDMs who received the infographic / eligible consent encounters), 3) consent to participation in this SWAT by patients/SDMs (number of patients/SDMs who consented / those approached), and 4) feedback questionnaire completion (number of patients/SDMs who completed the questionnaire / those who received it).
Results: Phase 1: We conducted two, two-hour focus groups with 5 participants (10 participants total). Participants identified important infographic design considerations (visual presentation, language) and content (study details, participation in research). Integration: Results from Phase 1 were used to develop a final consent infographic. Phase 2: Sixty-three patients were eligible for REMAP-CAP during the study period; 21 were eligible (33%) for the SWAT. Of these, 18 patients/SDMs (86%) received the infographic, 17 consented to the SWAT (94%) and 15 (88%) completed questionnaires. RCs completed case report forms for each consent encounter (n = 18, 100%).
Conclusions: We engaged individuals with lived experience to co-design a consent infographic. We achieved three of four pre-specified feasibility objectives during pilot testing of the infographic for a priori REMAP-CAP consent encounters. Although there were fewer eligible consent encounters than anticipated, we identified acceptable rates of infographic delivery, consent to SWAT participation and questionnaire completion.

Background: Informed consent documents educate patients and families about research participation. However, given their increasing length and complexity, consent documents can be challenging to understand, particularly in high-stress environments such as the Intensive Care Unit (ICU). Patient/Family Partners (PFP) identified that consent documents for REMAP-CAP are challenging to understand. REMAP-CAP is a trial which studies treatments for patients admitted to the ICU with pneumonia or COVID-19. PFP wanted to support communication between research staff and patients/families during the consent process.
Our study: The objective of our project was to develop and determine the feasibility of using an infographic, consisting of words and images, to supplement consent documents for REMAP-CAP. We planned to develop the infographic using input from patients, family members and research coordinators during focus groups. We also planned to use the infographic during real consent discussions for REMAP-CAP and to collect feedback from patients and family members who received the infographic, and research coordinators who used the infographic.
Our findings: We successfully developed an infographic for use at five hospitals in Ontario, Canada. We did not have as many opportunities to use the infographic as we expected. However, when we did, it was feasible to use the infographic and to collect feedback from patients, families and research coordinators. Findings from our study can be used to inform the design of similar tools for other trials and to inform a future study to understand if the infographic can improve the consent process for patients, families and research coordinators.
