Talsma, B. G., Solvoll T, and Hartvigsen G.: 'Interruption management for hospital communication systems: A user requirements specification' (manuscript) Wireless communication infrastructure in hospitals represents a core for information sharing between health care workers. Medical staff’s work situation is highly mobile, and important information is constantly shared between co-workers to provide high quality services to the patients. To be able to communicate at any place and at any time during shifts, physicians carry mobile communication devices, often several devices according to their role and responsibilities. This leads, in many situations, to a number of problems, especially regarding to unnecessary interruptions from these devices. This mainly happens due to the callers not being aware of the situation of the called person, or ignoring the situation and context of their colleagues. Such situations often lead to severe medical consequences, such as medication errors and mistakes during treatment, and should be solved. To tackle this problem, we used methods from Computer Supported Cooperative Work and Human Computer Interaction, including an ethnographic and interpretive field research approach, where user requirements were elicited using a scenario-based approach. The intention was to learn about the communication situation, include the users in the design and testing process, thus ensuring that the system is designed and developed according to the user’s communication pattern and needs. To develop the CallMeSmart system we used an iterative software engineering approach, denoted Unified Process. Summarizing, we confirmed that physicians and surgeons are unnecessarily interrupted by mobile communication devices during their daily work, and identified in which situations such interruptions occur. We proved that a context-sensitive system for mobile communication in hospital settings is a suitable solution to manage the balance between a physician’s availability and the interruptions they experience from mobile devices. Under this project, we designed and developed an interruption management system into the existing infrastructure at the Context Laboratory, in our case an Ascom UNITE communication platform, which is similar or compatible with the system used at University Hospital of North Norway. Furthermore, by being able to seamlessly integrate smartphones into the existing infrastructure, we enabled the inclusion of the pagers, messages and alarm systems into the developed context-sensitive system. The resulting system is called CallMeSmart, a context-sensitive communication system for mobile communication suitable for hospital usage. CallMeSmart is based on an Ascom/trixbox platform, and was designed to reduce interruptions due to wireless phones by improving awareness between the users carrying these devices. The system is designed for hospital environments and reduces interruptions using contextual information related to users, such as: location, availability status and personal commitments. CallMeSmart is intended to meet the new communication needs for health care workers. The main contribution of this thesis is concentrated around the overall research problem targeted by this Ph.D. project, built up by different research questions. The developed system, CallMeSmart, has been tested by real test users, physicians, and in the Context Laboratory simulating real scenarios. The users gave a positive feedback welcoming the system in their work, so the next step is to test and verify the system in real hospital settings.
