This paper reports on a current project exploring how wireless and mobile technologies, in this case Personal Digital Assistants (PDAs) and Tablet PCs, may be useful in clinical practices. In particular, the support and practices for coordination and communication among members in highly mobile health teams are focused. Their practice can be pictured as just-in-time access to information for coordination of care and treatment related to, but also different from, information traditionally stored in the patients' health records and clinical information systems (CIS). To facilitate discussion among and participation from various stakeholders, and between organizational contexts and responsibilities, we developed four video scenarios. The paper describes how development of these scenarios can be used in an organizational development setting to facilitate analysis and design of tools mindful of the relationships between complex and interwoven infrastructures of communication on one hand and just-in-time aspects ofa mobile clinical practice on the other.
