Critical Data Studies clarifies how data practice and priorities emerging from various domains of power exacerbate structural inequalities. If we recognize, reveal, and reject data practices that cast data as if they were neutral or fixed, we can ensure that our data practices as TPC professionals are more just. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Key lessons:</b> 1. Recognize that data are socially constructed and often incomplete. 2. Reveal the overarching social, political, cultural, and economic conditions that shape data collection and by extension, data itself. 3. Reject faulty or biased processes for data interpretation and analysis that perpetuate inequality. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Implications for practice:</b> By acknowledging the relationship between data and context, we can promote better, more just data practices, preparing TPC professionals to work alongside community stakeholders in intersectional coalitions and challenging the conditions that lead to unjust data that fail to represent, over-represent, or blatantly misrepresent the realities of vulnerable communities.

Using the data generated by both consumer- and medically-oriented wearable devices to assess and improve fitness, wellbeing, and specific health outcomes demands attention to the user experiences of such devices as well as to the kinds of claims being made about their promise (cf. Gouge & Jones, 2016). This special issue participates in such work by presenting case studies situated at the intersections of wearables, communication design, and rhetorical analysis that explore the health, justice, and wellness-oriented promises of specific wearables. In this introduction, we briefly survey the research on wearables in the fields of rhetoric and technical communication, preview the essays in the collection, and propose some areas for future work that might be of interest to technical communication, communication design, and rhetoric scholars.

This article argues that technical and professional communication (TPC) programs and specialists need to contribute more to health humanities scholarship and program curricula. The article reviews the writing courses offered by baccalaureate health humanities programs and “to support further TPC engagement in these programs” offers core generalizations and strategies for managing their approval process.

Transitional care communication events—such as discharge from hospital—are complex and dynamic: impromptu questions are asked and answered, documents are discussed and signed, and health-care professionals and patients with different knowledge must work together to establish understanding. This article examines a set of patient discharge instructions that bear substantial traces of impromptu conversation in the patient discharge communication process and argues that we need to do more to account for such exchanges as a part of the complex information our documentation must coordinate and make accessible for end users.
