This study relies on information theory, social presence, and source credibility to uncover what best helps people grasp the urgency of an emergency. We surveyed a random sample of 1,318 organizational members who received multiple notifications about a large‐scale emergency. We found that people who received 3 redundant messages coming through at least 1 synchronous communication source—for example, phone or face‐to‐face communication—perceived the urgency of the situation the most quickly, whereas those receiving official messages through asynchronous channels—most often text message—had the lowest sense of urgency. Our findings suggest that by understanding people's reactions to various kinds of redundant communication, organizations can design more strategic emergency messages that capture attention.

A key provision of the American Recovery and Reinvestment Act of 2009 mandated that electronic health records (EHR) be adopted in US healthcare organizations by 2015. The purpose of this study is to examine the communicative processes involved as healthcare workers implement an EHR and make changes, known as workarounds. Guided by theories in social influence, and diffusion of innovations, we conducted a survey of healthcare professionals using an EHR system in an organization. Our structural equation modeling (SEM) and multiple regression results reveal coworker communication, in the form of informal social support and feedback, play an important role in whether people engage in workarounds. Understanding this relationship is important because our study also demonstrates that workarounds predict healthcare employees' overall satisfaction with the EHR system. Specifically, workarounds are associated with higher perceptions of the EHR's relative advantage, higher perceptions of EHR implementation success, and lower levels of resistance to EHR change. This study offers a health communication contribution to the growing research on EHR systems and demonstrates the persuasive effects that coworkers have on new technology use in healthcare organizations.

The American Recovery and Reinvestment Act passed by the U.S. government in 2009 mandates that all healthcare organizations adopt a certified electronic health record (EHR) system by 2015. Failure to comply will result in Medicare reimbursement penalties, which steadily increase with each year of delinquency. There are several repercussions of this seemingly top-down, rule-bound organizational change-one of which is employee resistance. Given the penalties for violating EHR meaningful use standards are ongoing, resistance to this mandate presents a serious issue for healthcare organizations. This study surveyed 345 employees in one healthcare organization that recently implemented an EHR. Analysis of variance results offer theoretical and pragmatic contributions by demonstrating physicians, nurses, and employees with more experience in their organization are the most resistant to EHR change. The job characteristics model is used to explain these findings. Hierarchical regression analyses also demonstrate the quality of communication surrounding EHR implementation-from both formal and informal sources-is negatively associated with EHR resistance and positively associated with perceived EHR implementation success and EHR's perceived relative advantage.

This study explores hospital workers' experiences with workplace communication overload and its implications for effective safety and risk messaging in hospital organizations. We use a multi-step thematic analysis of interview (N = 12) and focus group (N = 8, 28 participants) data collected from hospital workers to analyze how they describe specific organizational communication channels influencing their communication overload. We specifically examine how workers' socially constructed channel affordances and constraints for sending/receiving safety information provide meaning to their communicatively overloaded states. Hospital workers explained that asynchronous channels such as e-mail and voicemail aggravated communication overload, while synchronous channels such as team huddles alleviated it. We discuss the implications of these results for the communication overload model by pointing to violations of communication channel preference and literature on the social affordances of communication channels. Study limitations and future directions are offered.
