Veterans with blood cancers: Clinical trial navigation and the challenge of rurality

Abstract

AbstractPurposeThe proportion of cancer patients who participate in clinical trials (CTs) remains low, despite an understanding of barriers to enrollment. The barrier of rural residence is relevant to Veterans, who more commonly live in rural areas than non‐Veterans. In this exploratory study, we aimed to examine geographic factors that could impede CT enrollment and to improve access to CTs for Veterans.MethodsTo assess the influence of rurality on the availability of CTs, we performed simulated searches using The Leukemia & Lymphoma Society's Clinical Trial Support Center (LLS CTSC) database. The LLS CTSC provides free CT education and navigation. In the second part of this study, we offered Veterans with blood cancers who received care at the Durham, Salem, Clarksburg, Sioux Falls, and Houston Veterans Administration (VA) Medical Centers referral to the LLS CTSC.FindingsIn simulated searches, we found significantly lower numbers of CTs open to enrollment in rural areas, compared to urban areas. In actual referrals, 33 Veterans were referred to the LLS CTSC, of which 15 (45%) lived in rural areas. Three Veterans enrolled in CTs. Patients declined referral or did not enroll in CTs for various reasons, including a desire to maintain care within the VA and/or to initiate therapy quickly.ConclusionsWe identified “clinical trial deserts,” which might hinder access and reduce CT participation for rural Veterans. Referral to the LLS CTSC promoted CT education and enrollment among a highly rural cohort of Veterans receiving care in the VA system.
