BACKGROUND: Nurse navigation can improve quality of cancer care and reduce racial disparities in care outcomes. Addressing persistent structurally-rooted disparities requires research on strategies that support patients by prompting structural changes to systems of care. We applied a novel conceptualization of social support to an analysis of racial equity-focused navigation and patient-reported outcomes. METHOD: We applied an antiracism lens to create a theory-informed definition of system-facing social support: intervening in a care system on a patient's behalf. Participants were adults with early-stage breast or lung cancer, who racially identified as Black or White, and received specialized nurse navigation ( RESULTS: Twelve percent of navigators' clinical notes documented system-facing support. Black participants received more system-facing support than White participants, on average (b = 0.78, 95% confidence interval [CI]: [0.25, 1.31]). The interaction of race*system-facing support was significant in a model predicting perceived racism in health care settings at the end of the study controlling for baseline scores (b = 0.05, 95% CI [0.01, 0.09]). Trends in simple slopes indicated that among Black participants, more system-facing support was associated with slightly more perceived racism
no association among White participants. DISCUSSION: The term system-facing support highlights navigators' role in advocating for patients within the care system. More research is needed to validate the construct system-facing support and examine its utility in interventions to advance health care equity.
