Sarcevic, Aleksandra (2009): Understanding teamwork in high-risk domains through analysis of errors. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 4651-4656. Available online
“Trauma care is an example of dynamic, complex, and safety-critical teamwork. The staff in trauma centers works under time pressure and lacks effective information technologies to support teamwork and reduce errors. This work presents a qualitative study that looked at the teamwork errors and their causes to better understand the challenges in providing computerized support for this user group.”

“Information transfer under time pressure and stress often leads to information loss. This paper studies the characteristics and problems of information handover from the emergency medical services (EMS) crew to the trauma team when a critically injured patient arrives to the trauma bay. We consider the characteristics of the handover process and the subsequent use of transferred information. Our goal is to support the design of technology for information transfer by identifying specific challenges faced by EMS crews and trauma teams during handover. Data were drawn from observation and video recording of 18 trauma resuscitations. The study shows how EMS crews report information from the field and the types of information that they include in their reports. Particular problems occur when reports lack structure, continuity, and complete descriptions of treatments given en route. We also found that trauma team members have problems retaining reported information. They pay attention to the items needed for immediately treating the patient and inquire about other items when needed during the resuscitation. The paper identifies a set of design challenges that arise during information transfer under time pressure and stress, and discusses characteristics of potential technological solutions.”

Sarcevic, Aleksandra, Lesk, Michael E., Marsic, Ivan and Burd, Randall S. (2008): Quantifying adaptation parameters for information support of trauma teams. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 3303-3308. Available online
“Trauma centers are stressful, noisy and dynamic environments, with many people performing complex tasks, and with little in the way of information support. Information must be prioritized and filtered to avoid overload or loss. This work quantifies the information-selection parameters that will guide adaptive user interfaces for trauma teams.”

“This paper describes an ethnographic study conducted to explore the possibilities for future design and development of technological support for trauma teams. We videotaped 10 trauma resuscitations and transcribed each event. Using a framework that we developed, we coded each transcript to allow qualitative and quantitative analysis of the trauma teams' collaborative processes. We analyzed teams' tasks, interactions, and communication patterns that support information acquisition and sharing. Our results showed the importance of team transactive memory, but also pointed to inefficiencies in communication processes, which enable the functioning of this collective memory system. Based on quantitative and qualitative observations of trauma teamwork, we present opportunities for technological solutions that may reduce the cognitive effort needed for maintaining the working memory of trauma teams.”

Velez, Maria, Tremaine, Marilyn Mantei, Sarcevic, Aleksandra, Dorohonceanu, Bogdan, Krebs, Allan and Marsic, Ivan (2004): "Who's in charge here?" communicating across unequal computer platforms. In ACM Transactions on Computer-Human Interaction, 11 (4) pp. 407-444
“People use personal data assistants in the field to collect data and to communicate with others both in the field and office. The individual in the office invariably has a laptop or a high-end personal workstation and thus, significantly more computing power, more screen real estate, and higher volume input devices, such as a mouse and keyboard. These differences give the high-end user the ability to represent and manipulate collaborative tasks more effectively. It is therefore useful to know what impact these differences have on work performance and work communications. Four different platform combinations involving a PC and a PDA were used to examine the effect of communicating via heterogeneous computer platforms. The PC platform used a mouse, a keyboard, and a 3-dimensional screen display. The PDA platform used a stylus, soft buttons, and a 2-dimensional screen display. A variation of the Tetris wall-building game called Slow Tetris was used as the subjects' collaborative task. A second factor in the experiment was role asymmetry. One subject was arbitrarily put in charge of the task solution in all of the combinations. An analysis of the solution times found that subjects with mixed platforms worked slower than their homogeneous counterparts, that is, a person in charge with a PC worked faster if his partner had a PC. An in-depth analysis of the communication patterns found significant differences in the exchanges between heterogeneous and homogenous combinations. The PC-to-PDA combination (with the person on the PC in charge of the solution) took significantly more time than the PC-to-PC combination. This extra time appears to come from the disadvantage of having a partner on the PDA who is unable to help in solving the problems. The PDA-to-PC combination took approximately the same amount of time as the PDA-to-PDA combination despite having one team member with a better representation. This member was, unfortunately, not in charge of the solution. The PDA-to-PC heterogeneous combination exhibited more direction giving, less one-sided collaboration, and more takeover attempts than any of the other combinations. Overall, roles were maintained in the partnerships except for the person with the PDA directing the person with the PC.”
