Unpacking the Realities and Complexities of Sensemaking: Government Practitioners' Experiences of Emergency Risk Communication.

During public health emergencies, government practitioners must rapidly make sense of the risk to human health and the emergency risk communication (ERC) options available. These practitioners determine what, how, and when information is communicated to the public. Recurring criticism of ERC indicates that the communication is not meeting the needs of the community. To improve ERC practice, it is therefore critical to understand practitioners' sensemaking in these complex and time-critical settings. This article unpacks the realities and complexities of sensemaking, the process by which practitioners create meaning from the information they receive about an emergency as it unfolds. Qualitative interviews gathered practitioners' lived experiences of public health emergencies, namely, smoke events (e.g., wildfires and industrial facility fires), and thematic analysis drew on sensemaking literature. The evidence shows that sensemaking is challenging, as practitioners experience pressure from the emergency context and organizational, political, and social expectations. Sensemaking for ERC comes with an underlying imperative to accurately make sense of the situation, in a timely manner and in a way that leads to the best health outcomes. Practitioners must balance creating plausible meaning (sensemaking) with the accuracy expected by stakeholders. The analysis also highlights how sensemaking scope is delimited by professional expert identities and roles within the emergency management system; that is, practitioners' understanding of their expertise and role, and that of other practitioners. Past lived experiences are viewed as key facilitators of both individual and collective sensemaking, and the history of similar public health events shapes sensemaking in this context.
