- Abstract
This cohort study assesses whether demographic factors of potential research participants and research personnel are associated with rates of patient participation in prospective ophthalmic clinical studies. Key Points: Question: What demographic factors of potential research participants and research personnel are associated with rates of patient participation in prospective ophthalmic clinical studies? Findings: In this cohort study including 1380 potential participants, patients from racial and ethnic minority groups and those with lower socioeconomic status were less likely to consent to participate in ophthalmic clinical studies. Concordance of race and ethnicity between patients and research staff was associated with improved enrollment. Meaning: Diverse clinical research teams may be associated with increased racial and ethnic minority patient enrollment and improved representation in ophthalmic clinical studies. Importance: Several ophthalmic diseases disproportionately affect racial and ethnic minority patients, yet most clinical trials struggle to enroll cohorts that are demographically representative of disease burden; some barriers to recruitment include time and transportation, language and cultural differences, and fear and mistrust of research due to historical abuses. Incorporating diversity within the research team has been proposed as a method to increase trust and improve engagement among potential study participants. Objective: To examine how demographic factors of potential research participants and personnel may be associated with patient consent rates to participate in prospective ophthalmic clinical studies. Design, Setting, and Participants: This retrospective cohort study included patients from an urban, academic hospital who were approached for consent to participate in prospective ophthalmic clinical studies conducted between January 2015 and December 2021. Main Outcomes and Measures: Multivariable logistic regression assessing associations between patient and research personnel demographics and rates of affirmative consent to participate was used. Results: In total, 1380 patients (mean [SD] age, 58.6 [14.9] years; 50.3% male) who were approached for consent to participate in 10 prospective ophthalmic clinical studies were included. Of prospective patients, 566 (43.5%) were Black; 327 (25.1%), Hispanic or Latino; 373 (28.6%), White; 36 (2.8%), other race and ethnicity; and 78 (5.8%) declined to answer. Black patients (odds ratio [OR], 0.32; 95% CI, 0.24-0.44; P <.001) and Hispanic or Latino patients (OR, 0.31; 95% CI, 0.20-0.47; P <.001) were less likely to consent compared with White patients. Patients with lower socioeconomic status were less likely to consent than patients with higher socioeconomic status (OR, 0.43; 95% CI, 0.33-0.53; P <.001). Concordance between patient and research staff race and ethnicity was associated with increased odds of affirmative consent (OR, 2.72; 95% CI, 1.99-3.73; P <.001). Conclusions and Relevance: In this cohort study, patients from underrepresented racial and ethnic groups and those with lower socioeconomic status were less likely to participate in ophthalmic clinical studies. Concordance of race and ethnicity between patients and research staff was associated with improved participant enrollment. These findings underscore the importance of increasing diversity in clinical research teams to improve racial and ethnic representation in clinical studies.
