    Background: US regulatory framework for advanced heart failure therapies (AHFT), ventricular assist devices, and heart transplants, delegate eligibility decisions to multidisciplinary groups at the center level. The subjective nature of decision‐making is at risk for racial, ethnic, and gender bias. We sought to determine how group dynamics impact allocation decision‐making by patient gender, racial, and ethnic group. Methods and Results: We performed a mixed‐methods study among 4 AHFT centers. For ≈ 1 month, AHFT meetings were audio recorded. Meeting transcripts were evaluated for group function scores using de Groot Critically Reflective Diagnoses protocol (metrics: challenging groupthink, critical opinion sharing, openness to mistakes, asking/giving feedback, and experimentation; scoring: 1 to 4 [high to low quality]). The relationship between summed group function scores and AHFT allocation was assessed via hierarchical logistic regression with patients nested within meetings nested within centers, and interaction effects of group function score with gender and race, adjusting for patient age and comorbidities. Among 87 patients (24% women, 66% White race) evaluated for AHFT, 57% of women, 38% of men, 44% of White race, and 40% of patients of color were allocated to AHFT. The interaction between group function score and allocation by patient gender was statistically significant (P=0.035); as group function scores improved, the probability of AHFT allocation increased for women and decreased for men, a pattern that was similar irrespective of racial and ethnic groups. Conclusions: Women evaluated for AHFT were more likely to receive AHFT when group decision‐making processes were of higher quality. Further investigation is needed to promote routine high‐quality group decision‐making and reduce known disparities in AHFT allocation.

    Race and Gender-Based Perceptions of Older Septuagenarian Adults
    (Mary Ann Liebert, 2022-11-14) Melton, Forest; Palmer, Kelly; Solola, Sade; Luy, Luis; Herrera-Theut, Kathryn; Zabala, Leanne; Knapp, Shannon M.; Yee, Ryan; Yee, Erika; Calhoun, Elizabeth; Thomas Hebdon, Megan C.; Pool, Natalie; Sweitzer, Nancy; Breathett, Khadijah; Medicine, School of Medicine
    Objectives: Older adults face racism, sexism, and ageism. As the U.S. population ages, it is important to understand how the current population views older adults. Methods: Participants recruited through Amazon's Mechanical Turk provided perceptions of older Black and White models' photographs. Using mixed-effect models, we assessed interactions between race and gender of participants and models. Results: Among Participants of Color and White participants (n = 712, 70% non-Hispanic White, 70% women, mean 37.81 years), Black models were perceived as more attractive, less threatening, and sadder than White models, but differences were greater for White participants (race-by-race interaction: attractive p = 0.003, threatening p = 0.009, sad p = 0.016). Each gender perceived their respective gender as more attractive (gender-by-gender interaction p < 0.0001). Male and female participants perceived male models as happier than female models, but differences were greater for male participants (p = 0.026). Irrespective of participant age group, women were perceived as more threatening (p = 0.012). Other perceptions were not significant. Discussion: Participants had few biases toward older Black and White models, while gender biases favored men.
