Institutional barriers to clinical trial exploration experienced by the Latinx community

This study evaluated two types of barriers that the authors deemed important to resolve during the early stage of cancer clinical trial exploration by Latinx community members. One was the accessibility of information provided on cancer centers’ websites. The other was the telephone responders’ clinical trial knowledge and their conveyance of a warm welcome to Latinx callers inquiring about the centers’ clinical trials. Simulated clinical trial inquiry calls were made to 17 National Cancer Institute-designated centers in this study. The centers were located in cities where the Latinx community accounted for at least 25% of the population, thereby justifying center-wide efforts to encourage the Latinx community to explore clinical trial participation. A rubric was developed to determine and quantify a Total Score that was partially composed of the accessibility of clinical trial information displayed on each cancer center’s website. A research assistant gathered information by posing as a person calling the cancer center to inquire about clinical trials on behalf of a family member with limited English proficiency and evaluated their response using a “mystery shopper” method of data collection. The warmth and sense of welcome conveyed by the telephone responder was also quantified and included in the rubric’s Total Score. A perfect Total Score reflected the likely existence of an environment that would encourage Latinx community members to continue exploring clinical trials, i.e., removed or diminished possible barriers. Welcoming characteristics, such as those elements included in the scoring rubric, can be monitored regularly to assure that centers are consistently conveying an optimal sense of welcome to the Latinx community, while also providing accessible clinical trial information. Among the 17 cancer centers, no correlation was found between the size of the Latinx population served and each center’s Total Score.
