Objective:
This study explores the experiences and perceptions of people living with amyotrophic lateral sclerosis (pALS), their caregivers, and healthcare providers regarding participation in clinical trials. The study tested the hypothesis, based on existing literature, that geographic distance from multidisciplinary ALS clinics is the primary barrier to awareness and participation in clinical trials.
Methods:
A road trip was conducted to engage individuals, particularly those residing more than 90 miles from specialized clinics. Qualitative and semi-quantitative methods were used to collect data from in-person interviews conducted with pALS, their caregivers, and healthcare providers in urban (high population density), suburban (residential areas on the outskirts of urban centers), and rural (sparsely populated) settings across the East Coast of the US. Thematic analysis was employed to interpret the data.
Results:
Based on the interviews, a trusted, supportive, and knowledgeable medical team knowledgeable about ALS research emerged as a critical factor influencing patient participation decisions. Geographic distance alone did not meaningfully impact research interest or awareness. Healthcare providers faced challenges, including time constraints and limited access to updated information about studies, which hindered their ability to promote participation. Healthcare providers cited informal partnerships with advocacy organizations and research centers as crucial for facilitating research participation.
Conclusions:
Tailored communication strategies that leverage established relationships between pALS and their trusted healthcare providers may enhance research participation. As decentralized research models evolve, improving trial education and access and fostering knowledge and trust could significantly boost enrollment in ALS clinical research.

Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
