Abstract
The participation of underserved ethnic minorities in clinical research is critical to achieving progress in cancer control. Ethnic minority patient accrual in clinical trials is a formidable challenge that requires patient trust, commitment, and overcoming of barriers. Racial and ethnic minorities make up about 40% of the United States population, yet are not well represented in research studies. Less than 10% of all patients with cancer enrolled in clinical trials are minorities. Diverse participation may lead to more generalizable results for under-represented groups, more best practices for prevention and treatment to specific minority groups, increase in knowledge and awareness of disparities about cancer, and a more accurate reflection of the United States' increasingly diverse population. Although there is a proliferation of patient navigation programs to increase health care among the underserved, there is little known on its potential effects as a strategy to enhance minority clinical trial and biospecimen accrual.
City of Hope has built a functional and sustainable program for addressing health inequity, which includes training a network of community research navigators (CRN) to address gaps in knowledge, medical mistrust, and access, and navigate participation and engagement of under-represented groups in research. The research navigator program draws from the patient navigation and promotora model and is a novel and innovative application to this approach. This approach has utility and applicability to address research participation barriers, including trust and referrals. It promises sustainability and cost effectiveness as trained CRNs can deliver the program. The Community Research Navigator (CRN) project enhances community advocates' capacity by training community health leaders/promotoras as community research navigators (CRN) to widen the dissemination of the clinical trial and research participation enrollment for increased ethnic minority participation in clinical trials and health-related research. CRNs attended a 1-day training on clinical trials and research. The training included educating and encouraging individuals to proactively think about and discuss clinical trial participation with their family, friends, and health care providers; disseminating information about specific research studies, targeting the African and Latino communities; and referring individuals to specific biospecimen, clinical trials, and population studies. In total, we trained and mentored a team of 14 CRNs. Participants were 24-66 years old; most were female (86%), Latino (69%), and single (43%). After participating in the training, participants were more likely to correctly define HIPAA (p=.040) and the types of clinical trials (p=.038). In addition, CRNs were more likely to encourage clinical research participation among their family after the training (p=0.034). Further, we measured confidence in various domains, including: increase in confidence in describing the purpose and process of clinical research (p=0.006); educating minority communities about clinical trials (p=0.045); and providing informational workshops/forums on clinical research (p=0.046). Participants had an increase in overall confidence (p=.033). Our findings demonstrate that the CRN strategy holds promise in increasing minority participation in cancer clinical trials. It is an innovative application of the extensively studied patient navigation approach that warrants research. Future research should focus on the CRN project as a cost-effective tool for enrollment and retention of ethnic minorities in cancer clinical trials and the potential of enhancing clinical trial understanding outcomes among participants.
