This dissertation examines the relationship between diagnostic communication practices and deliberative rhetoric through the lens of Actor-Network theory and feminist theory. Specifically, I argue that Bruno Latour's Actor-Network Theory (ANT) provides a generative framework for tracing diagnostic networks as it accounts for uncertainty, dispersed agency, community stakeholders, and nonhumans. The chapters explore how a networked approach to diagnosis opens up opportunities to reform doctor-patient relationships, expands our conceptions of diagnostic actants, suggests ways to respond to patients living at risk for disease, and broadens our understanding of ethos in healthcare contexts. Furthermore, I also consider how a networked framework can help us comprehend how public misdiagnoses happen so we can prevent them in the future. I conclude by advocating for healthcare providers to reform diagnostic communication practices to account for the agency and expertise of non-specialist stakeholders, particularly patients. I also explore methods for intervening within global health networks and addressing the intersectional problems they collaboratively solve.
