Study Details

Brief summary:

This clinical trial explores and implements methods to improve informed decision making (IDM) regarding precision oncology tests amongst veterans with prostate cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Precision oncology, the use of germline genetic testing and tumor-based molecular assays to inform cancer care, has become an important aspect of evidence-based care for men with advanced prostate cancer. Veterans with metastatic castrate-resistant prostate cancer may not be carrying out IDM due to unmet decisional needs. An informed decision is a choice based on complete and accurate information. The information gained from this study will help researchers develop a decision support intervention (DSI) and implement the intervention. A DSI may serve as a valuable tool to reduce ongoing racial disparities in genetic testing and encourage enrollment to precision oncology trials.

Interventions and Outcome Measures

Arms

experimental: CLOSED TO ENROLLMENT: Stage 1 & 2: Patients, Caregivers, Providers

Patient participants will be instructed to install a mobile app to record their medical appointment, which research staff will use to analyze patient-provider communication. All participants will undergo semi-structured interviews and/or focus groups. Post appointment follow-up with surveys and assessments regarding knowledge of disease information, quality of life, and other measures will be administered after the provider-patient appointment.

experimental: Stage 3: Patients, Caregivers using developed GA platform

About 14 days prior to scheduled germline testing appointment, patients and caregivers call or meet with a coach to select decision aid GA platform preference delivery (online, print, or both online and print), review the GA online platform, and possibly undergo consultation and training for audio recording of the scheduled appointment. Patients and caregivers attend the scheduled germline testing appointment on day 1. Patients complete surveys and patients and caregivers may complete an interview on study. Providers participate in focus groups and complete surveys on study.
