Purcell, Janine A., Williams, Linda, Scott, Jeanie, Russ, Alissa L., Drews, Frank and Speir, Ross (2011): Human Factors Engineering in the Department of Veterans Affairs: Operations and Research Initiatives Related to Healthcare Information Technology and Medical Devices. In: Proceedings of the Human Factors and Ergonomics Society 55th Annual Meeting 2011. pp. 677-679.
“The Department of Veterans Affairs (VA) health care system currently includes 152 medical centers, with at least one in each state, Puerto Rico, and the District of Columbia. VA operates more than 1,400 sites of care, including 909 ambulatory care and community-based outpatient clinics, 135 community living centers (nursing homes), 47 residential rehabilitation treatment programs, 232 Veterans Centers and 108 comprehensive home-care programs. In 2010, the system supported 75.6 million outpatient visits and 679,000 inpatient admissions.1, 2 In 1999, the VA National Center for Patient Safety (NCPS) was established to lead the VA's patient safety efforts and to develop a culture of healthcare safety throughout the Veterans Health Administration. The NCPS program promotes the use of human factors engineering methods that focus on how users interact with technology. Within the Department of Veterans Affairs various organizations have expanded the use of human factors engineering methods as a key element in addressing patient safety from a systems-based perspective. These entities include a range of groups that work in operational and research domains to identify and mitigate root causes of error with traditional medical devices and healthcare information technology to reduce the likelihood of patient harm while continuing to enhance and advance the design of healthcare tools and environments. The expertise of the panel members includes human factors and biomedical engineering, cognitive psychology, information science, healthcare information technology and informatics, and clinical knowledge of medical technology and nursing. Each panelist will briefly introduce the organization they work in, provide an overview of their human factors activities, and briefly describe example(s) of specific projects, with emphasis on the benefit or lessons learned via these activities. Attendees will learn strategies to apply human factors engineering in healthcare and deepen their understanding of human performance challenges in this domain.”

Purcell, Janine A. (1994): Statistical Process Control Charting Applied to the Analysis of Human Performance in Computer-Supported Environments. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 350-354.
“To develop usable Human-Machine Systems, we need Tools to evaluate and measure the length of learning periods, error rate, response time, and transfer of learning in the human operators of these systems (Whiteside, Bennett, and Holtzblatt, 1988). This research explores the use of Statistical Process Control (SPC) charts as a tool to visualize and analyze performance in a decision-making task. The data submitted to control charting was collected in an experiment that explored the effect of order of training or experience in working with alternate display formats. Results for an individual subject as well as a summary for one of the four experimental groups are discussed. Suggestions for further applications of these techniques are offered.”

Zachary, Wayne, Zaklad, Allen L., Hicinbothom, James H., Ryder, Joan M. and Purcell, Janine A. (1993): COGNET Representation of Tactical Decision-Making in Anti-Air Warfare. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. pp. 1112-1116.
“Human tactical decision making in Naval Anti-Air Warfare (AAW) is time-critical and is performed in a multiple-task, team-based environment. These aspects make this domain extremely challenging for traditional cognitive modeling techniques. The COGNET (COGnition as a NEtwork of Tasks) framework, however, is inherently designed for real-time, multi-tasking work, and, with extensions to accommodate team decision processes, proved suitable for modeling AAW decision making in the Navy's Tactical Decision Making Under Stress (TADMUS) program. A COGNET model of AAW domain expertise is described, along with Decision-Support System (DSS) design principles derived from the COGNET AAW model and the underlying COGNET framework.”

Ryder, Joan M., Zaklad, Allen L., Zachary, Wayne and Purcell, Janine A. (1992): A Cognitive Framework for Integrated Embedded Training and Decision Aiding. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1269-1273.
“This research has developed a theoretically-based cognitive model and design framework for Integrated Decision Aiding/Training Embedded Systems (IDATES). Based on a review of empirical studies of novice-expert differences and of theoretical and computational models of skill acquisition, we defined a three-stage cognitive hierarchy model as the basis for our IDATES framework. The levels of novice, intermediate, and expert are discrete stages which differ along two primary dimensions: problem representation and problem-solving procedure. Both decision aiding and training must be targeted to the problem representation and cognitive processes of the user/trainee. Thus, there must be three levels of decision aiding targeted to novice, intermediate, and expert decision makers. Furthermore, there are two types of training: incremental training to improve performance within each of the three expertise levels, and representational training to elicit a jump to the next higher level of problem representation. Two implications arise from the IDATES cognitive model. First, integrated cognitive/behavioral task analyses are able to drive both the embedded training requirements and the decision aiding requirements, although the three skill levels must be separately addressed. Second, a single integrated architecture can underlie all the decision aiding and embedded training components of a given IDATES application.”

Purcell, Janine A. and Coury, Bruce G. (1991): The Impact of Alternating Between Integral and Separable Displays in a Multidimensional Decision-Making Task. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 1579-1583.
“Research into the format of visual displays of multidimensional data has revealed relative superiority of certain formats in relation to the nature of task demands such as fault diagnosis versus fault detection. Previous research also suggests that order of training or experience in working with alternate display formats might also influence the ability of operators to gain the full benefits of these display formats. This last factor comes into play during the redesign of existing displays and the design of multiple display environments in domains such as nuclear process control, tactical and commercial flight, and anesthesia monitoring. The experiment described in this paper sought to further examine and clarify the types of performance decrements that can emerge after switching visual display formats used to support a complex decision-making task (Purcell and Coury, 1988). Accuracy and response time performance demonstrated that transfer of training was asymmetric after the switch. These results indicate that the order in which operators learn to use a given format of visually displayed data can enhance or hinder their subsequent use of alternate display formats. Redesign efforts and/or the use of multiple display formats in complex decision-making settings must address these effects.”

Purcell, Janine A. (1990): A Cognitive Modeling Technique for Complex Decision Strategies. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 254-258.
“Accurate models of operator decision making have been advocated by a number of researchers as a fundamental component of system design (Glenn, (1989); Norman, (1986); and Rasmussen, (1985)). Such models can be used to strengthen the design integrity of decision support systems in which tasks are allocated between human and computer. In this investigation, a cognitive modeling technique based on the GOMS model of Card, Moran, and Newell (1983) was used to analyze the composition and structure of decision-making strategies in a multidimensional diagnostic task. Two general strategies emerged along with the finding that certain strategies predominated according to visual display format. The methodology offers a promising approach to the analysis of verbal and retrospective protocol data solicited in conjunction with complex decision-making tasks.”

Purcell, Janine A. and Coury, Bruce G. (1988): Asymmetric Transfer of Training Between Integral and Separable Displays. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1366-1370.
“The type of display employed during operator training may affect the formation of an operator's internal model of the system. In this experiment, subjects were divided into two groups and trained to classify instances of system state using either a configural or digital display. During extended practice the subjects were then switched to the alternate display type; those trained on the configural display now worked with the digital display, and vice verse. Results indicate that asymmetric transfer of training occurred; those who switched from the digital to the configural display outperformed the other group by a significant margin in term of accuracy. Results are discussed in terms of the impact of display type on the formation of the operator's internal model and bias of processing strategy in transfer situations.”
