Abstract B160: Assessing patient experience in cancer clinical trial participants: Results from a rapid umbrella review with an equity lens

Abstract Introduction: Clinical trials are an important part of cancer care, yet research assessing patient experience in cancer clinical trials is sparse. Ensuring that the patient voice is heard and valued in the context of clinical trials is critical to the delivery of high-quality, patient-centered, and equitable cancer care. Furthermore, understanding the aspects of cancer clinical trials that are important to and reported by patients may inform strategies to address barriers to clinical trial participation, improve diversity in clinical trials, and advance health equity, particularly among populations underrepresented in clinical research. This rapid umbrella review sought to understand how patient experience is assessed in cancer clinical trials and to identify opportunities to integrate an equity lens. Methods: PubMed, Embase, Cochrane, and CINAHL databases were searched for systematic reviews that identify and describe development, use, or testing of tools/instruments assessing patient experience of cancer clinical trial patients. The search strategy was collaboratively developed with an NIH Librarian, using a combination of key terms to describe: 1) patient experience, 2) clinical trials, 3) healthcare delivery, and ) systematic reviews. The search was limited to publications in the English language and a date range of 2018-2024. One co-author completed the title and abstract review based on the inclusion criteria. Two reviewers will then independently completed the full text review, quality appraisal, and data abstraction for all included studies. All authors will synthesize data into matrix tables and narratively summarize into key themes. Discrepancies were resolved through discussion. Results: Out of 1,751 yielded search results, 151 articles were preliminarily identified. Upon further reading of the full texts, the final list of included articles meeting inclusion criteria will be reported using Covidence. Summary findings from this rapid umbrella review will include the number of studies identified, clinical trials population, a description of the patient experience measures, domains, findings, as well as opportunities for health equity integration using the PROGRESS-Plus Framework. Conclusion: Equitable representation in clinical trials will require intentional efforts to understand and enhance the experience of patients on clinical trials across diverse patient populations, as well as address barriers to participation. However, there are several research gaps that limit our understanding in this area, including a lack of consistent definitions, patient experience domains; availability and use of standardized, validated measures for clinical trial populations, and knowledge about what factors differ and influence patients’ experiences, particularly among populations underrepresented in clinical research. Attention to these gaps will facilitate a greater understanding of patient needs, experiences, and barriers, and may promote actionable strategies to increase access to, inclusion of, and diversity in cancer clinical trials.
