Understanding the Barriers to Clinical Trial Referral and Enrollment Among Oncology Providers Within the Veterans Health Administration.

Introduction: Clinical trials are essential for advancing treatment options in oncology while providing cancer patients with innovative care; however, few cancer patients are referred to clinical trials. System-, provider-, and patient-level barriers to clinical trial participation have been described but have not been studied in the Veterans Health Administration (VHA). Although the VHA has engaged in several initiatives to improve Veteran's access to clinical trials, including the National Cancer Institute and VA Interagency Group to Accelerate Trials Enrollment program and VHA work on the White House Cancer Moonshot, further research is needed to understand the multifaceted challenges underlying limited enrollment for Veterans who receive care in the VHA system.
