Patient and caregiver motivators and barriers to eczema clinical trial participation: Analysis of survey data

Abstract Background Eczema clinical trials (CTs) are increasing in number, yet participation across the eczema community is low. Little is known about patient characteristics and views on motivators and barriers to CT participation (CTP). Objectives Determine factors that motivate or impede participation in eczema CT and respondent characteristics associated with these factors. Methods Qualitative thematic analysis was performed on open‐ended questions from an online survey that collected respondent demographics, understanding of and experience with CTs, and drivers/barriers to CTP. Mixed‐methods analysis included 924 respondents, 728 (78.8%) adults with eczema and 196 (21.2%) caregivers of children with eczema. Results A large proportion (71.8%) of respondents would potentially participate in CTs. The most common theme for why a respondent considered or would explore CTP was burden of disease (81.0% and 57.3% respectively). Among those who participated in or considered a CT, caregivers ( p = 0.001) reported fewer altruistic motivations compared to adult patients, with trends towards men citing disease burden more (57.0% vs. 50.9%) and altruism less (14.5% vs. 19.2%) than women. Lack of awareness (57.7%) was the most common reason for never having considered a CT. Among those who never considered CTP, age ( p = 0.012) and eczema severity at its worst ( p = 0.002) were associated with reasons why they never participated. Specifically, older and less severe patients had greater perceptions of eligibility as a barrier to CTP. Caregivers more commonly cited fear of CT risks (20% vs. 11.4%) compared to adult patients who cited accessibility concerns (17.7% vs. 8.6%) as barriers to CT exploration. A subgroup of respondents that never considered CTP and extremely unlikely to consider CTs cited more fears/risks/unknowns and accessibility barriers to CTP. No significant differences in motivators or barriers were observed across race/ethnic groups and urban/rural populations. Conclusions Motivating factors for CTP include greater disease burden; lack of awareness represents a large barrier. Healthcare providers are trusted intermediaries with ability to refer and inform about CTs; they have a potentially significant role in raising awareness and discussing eczema patient/caregiver perspectives related to CTP. Investigators should tailor recruitment approaches and study design where possible to address identified motivators and barriers.
