Underserved patient populations characterized by low income, lack of insurance, low levels of education, and minoritized status face significant barriers when accessing clinical trials. To better understand these challenges, patients from a safety-net county hospital were surveyed on their perspectives on clinical trials, barriers to care, and facilitators of participation.
Methods
Patients ≥ 18 years old with histologically confirmed non-Hodgkin lymphoma (NHL) who received care at Lyndon B. Johnson Hospital, a safety-net county hospital in Houston, Texas, were invited to participate regardless of treatment status. A self-administered questionnaire was used and offered in English or Spanish. The questionnaire included a total of 53 items with an additional 13 demographic items assessing patient sociodemographic factors and knowledge of clinical trials. Questions also addressed barriers/facilitators of trial participation and respondent willingness to participate in a trial based on certain scenarios.
Results
Of the 136 patients invited to participate, a total of 49 participants diagnosed with NHL consented to the study and all completed the survey (participation rate 36%). Twenty-seven (55%) surveys were completed in Spanish. Participants self-identified as Hispanic (N=35, 71.4%), African American (N=6, 12.2%), non-Hispanic white (N=7, 14.3%), and Asian/Pacific Islander (N=1, 2%). This cohort included Diffuse Large B-cell lymphoma NOS (DLBCL) [32%], Follicular Lymphoma (FL) [28%], Marginal Zone lymphoma (12%). There were several patients with rare histologies such as Burkitt’s lymphoma (4.2%); Mantle Cell lymphoma (4.2%), Plasmablastic lymphoma (4.2%) and T-cell lymphoma (4.1%). The majority of participants reported a commute of less than an hour away to the doctor’s office (83%) with almost all participants commuting less than 2 hours (98% with 2% missing an answer). Participants were a median age of 55 years old (range 22–80), majority female (51%), less than a bachelor’s degree as highest education (91.8%) and earning < $35,000 (49%). Among respondents, 89.8% had not participated in a clinical trial for their cancer. Only 36.7% of respondents reported that they understood what a clinical research study as “somewhat well,” while 30.6% reported their understanding as “not very well.” Regardless, a majority were very willing (38.8%) or somewhat willing (36.7%) to participate in a trial as their initial course of treatment. Respondents’ biggest concerns were the cost of a clinical trial (61.2%), not being able to contact the research team with questions (38.8%), and frequency of clinic visits (32.7%). The most helpful resources that participants identified to reduce participation burden were educational resources such as written materials (77.6%), videos (67.3%), an explanation of the study in their language (65.3%), insurance aid (75.5%), and flexible study visit times (65.3%). Notably, 26.5% of participants responded that they believed they had received medication from a doctor as part of an experiment without their permission. When asked which outcome would most influence their decision to participate in a trial, 79.6% of participants rated the possibility of improving quality of life by decreasing pain and increasing activity levels as very important. Fewer patients (55%) rated other outcomes such as types of side effects (55%) and possibility of pain/discomfort (59%) as very important.
Conclusions
The majority of patients with NHL who participated in this observational study had little or no previous exposure to or understanding of cancer clinical trials. We identified common barriers to participation including out-of-pocket costs, the ability to contact the research team, and the frequency of clinic visits that should be addressed with specific identified resources to reduce participation burden. Interventions guided by these data should be implemented and evaluated to improve clinical trial participation for patients with lymphoma.
