Abstract
The purpose of this qualitative study was to explore how digital tools and community outreach can improve recruitment and retention in clinical trials, particularly among underserved populations. This study examined key barriers to participation, the potential benefits and limitations of digital tools, and strategies to engage underrepresented groups. Surveys were conducted with healthcare professionals (HCPs) and community members to gather perspectives on participation in clinical research. NVivo was used to code and analyze data. The analysis identified themes related to cultural barriers and trust, awareness, logistical barriers and accessibility, structural barriers and relevance, digital tools, and engagement. Participants were expected to describe challenges such as mistrust of the healthcare system, limited awareness of clinical trial opportunities, strict eligibility requirements, and logistical constraints related to transportation, scheduling, and financial strain. Digital tools were viewed as helpful for communication and convenience, though concerns about digital literacy and reliable internet access emerged. Engagement remained as a central factor, with an emphasis on building trust, strengthening communication, and providing outreach in familiar community settings. Overall, this study aimed to provide practical strategies that support more equitable, inclusive, and representative clinical trial practices.
