Summary: Elderly people often need support in everyday situations -- e.g. common daily life activities like taking care of house and garden, or caring for an animal are often not possible without a larger support circle. However, especially in larger western cities, local social networks may not be very tight, friends may have moved away or died, and the traditional support structures found in so-called multi-generational families do not exist anymore. As a result, the quality of life for elderly people suffers crucially. On the other hand, people from the broader neighborhood would often gladly help and respond quickly. With the project Wir im Kiez we developed and tested a multimodal social network app equipped with a conversational interface that addresses these issues. In the demonstration, we especially focus on the needs and restrictions of seniors, both in their physical and psychological limitations.

Summary: Cognitive task analysis (CTA) methods are most widely known for their contributions to military, nuclear power plant, and aviation research. In recent years, however, these methods have been adapted and applied with increasing frequency to address issues in healthcare. CTA methods have been used in the context of designing and integrating health information technology, in pursuit of improved patient safety, and as a means to improve education and training. This panel will 1) reflect on strategies for tailoring CTA methods for use in a range of healthcare settings, 2) highlight challenges to conducting CTA in healthcare settings, and 3) highlight important contributions of CTA in addressing challenging issues in healthcare today.

Summary: The rise of Social Media creates a wealth of information that can be very valuable for private and professional users alike. But many challenges surrounding this relatively new kind of information are yet unsolved. This is true for algorithms that efficiently and intelligently process such data, but also for methods of how users can conveniently access it and how results are displayed. In this paper we present a tool that lets users perform exploratory search on several Social Media sites in parallel. It gives users the opportunity to explore a topic space, and to better understand facets of current discussions.

Summary: With the United States national goal and incentive program to transition from paper to electronic health records (EHRs), healthcare organizations are increasingly implementing EHRs and other related health information technology (IT). However, in institutions which have long adopted these computerized systems, such as the Veterans Health Administration, healthcare workers continue to rely on paper to complete their work. Furthermore, insufficient EHR design also results in computer-based workarounds. Using direct observation with opportunistic interviewing, we investigated the use of paper- and computer-based workarounds to the EHR with a multi-site study of 54 healthcare workers, including primary care providers, nurses, and other healthcare staff. Our analysis revealed several paper- and computer-based workarounds to the VA's EHR. These workarounds, including clinician-designed information tools, provide evidence for how to enhance the design of the EHR to better support the needs of clinicians.

Summary: 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.

Summary: Within the last decade, there has been a growing emphasis on applying human factors principles in the healthcare domain, and although human factors is a well-established scientific discipline, it is still a relatively new concept for the healthcare community. Educating healthcare audiences on the goals, history, and contributions of the human factors discipline may dispel misconceptions; preserve the integrity of this scientific discipline; inform healthcare stakeholders about the value of human factors research; and increase the uptake of human factors principles in the healthcare domain. Panel members will share their views on human factors education for healthcare audiences, including their past experiences, personal successes, and insights on the challenges that remain. Panelists will also engage the audience in an open discussion to generate novel ideas on how to advance the healthcare community's understanding of the human factors discipline.

Summary: Designing systems for the special interests and needs of older user has become an important subject. However, necessary usability evaluations are time and resource consuming. One way of automation lies in simulating UI use. Since substantial sensory and cognitive age-related effects on the human visual system have been observed, mechanisms of Visual Attention (VA) are promising candidates for simulating GUI interactions specific for older users. This article discusses VA mechanisms relevant for simulating age-related effects in GUI interactions. An integration of such mechanisms is discussed on basis of the MeMo workbench, a rule-based approach that uses UI interaction simulations for uncovering usability problems. In the end, simulation of GUI interactions cannot replace human-based usability evaluation, but can provide early feedback for GUI designs, reducing time and resource demands for evaluations. In that, VA provides an instrumental framework for considering age-related effects in simulations of GUI interactions by older users.

Supporting cognition and decision making in clinical work HEALTH CARE: HC3 -- Supporting Cognition and Decision Making in Clinical Work / Gorman, Paul N. / Richardson, Joshua / Russ, Alissa / Militello, Laura G. / Xiao, Yan Proceedings of the Human Factors and Ergonomics Society 54th Annual Meeting 2010-09-27 v.54 p.821-825

Summary: Clinical decision support systems and other health information technologies are being implemented in healthcare organizations to enhance clinician performance by helping to overcome the limits of human cognition. In spite of gains achieved with these systems, significant problems remain, including unexpected complexity and sometimes harmful effects, and persistent use of paper-based cognitive artifacts. This panel will explore current research that is meant to help us better understand the implications of clinical decision support and cognitive support, and develop novel approaches that are intended to take better advantage of the complementary capabilities of human and machine cognition.

The Workflow of Computerized Medication Ordering in Primary Care is Not Prescriptive HEALTH CARE: HC5 -- Health Care Workflow, Research Implications / Russ, Alissa L. / Saleem, Jason J. / McManus, M.

Summary: While the potential benefits of computerized provider order entry (CPOE) are well recognized, little is known about how prescribers have integrated electronic medication ordering into other aspects of patient care. As part of a larger investigation of computerized medication alerts, we observed and opportunistically interviewed 20 primary care prescribers at a major Veterans Affairs Medical Center (VAMC). Participants were recruited from each of the VAMC's 5 primary care clinics and included physicians, nurse practitioners, and clinical pharmacists. Prescribers were observed as they ordered mediations via the CPOE system during routine patient care. In total, observations included 91 routine patient encounters across 66.5 hrs of observation. This paper provides illustrative case examples of how prescribers have integrated CPOE into medication decision-making processes and other patient care tasks. Results demonstrate that CPOE workflow varies widely among prescribers. In addition, results indicate that there are trade-offs associated with using CPOE with the patient in the exam room versus outside of the exam room. Findings may have implications for provider-patient relationships, workflow efficiency, and medication safety, and may ultimately enhance the effectiveness of CPOE in primary care.

A Novel Tool to Track and Analyze Qualitative Usability Data: Lessons Learned from the VAs Personal Health Record INTERNET: I2 -- Internet and Social Systems / Russell, Scott A. / Saleem, Jason J. / Haggstrom, David A. / Russ, Alissa L. / Chumbler, Neale R.

Summary: We developed a User-Testing Database to be able to process a greater amount of user data, from multiple sources of data, at a much finer level of granularity, and to be able to aid in a more sophisticated analysis, including specific queries of usability data than a typical "manual"-based usability analysis. In this paper, we demonstrate our User-Testing Database as applied to a usability assessment of the Veterans Affairs (VA) My HealtheVet personal health record. The usability test included 24 Veterans who completed a series of scenarios in the usability lab at a Midwest Veterans Affairs Medical Center (VAMC). The User-Testing Database facilitated reduction of data gathered from video review, facilitator notes, and debrief notes into 1160 observations that were sorted into conceptual bins and summarized for the designers of the personal health record. From creation of the database to completion of the reports took four months and did not require extensive knowledge of qualitative analysis techniques. We argue a User-Testing Database can allow other usability studies to increase the number of participants and the granularity of the data without prohibitively increasing the amount of time and experience required to process the data gathered.

Healthcare Workers' Perceptions of Information in the Electronic Health Record HEALTH CARE / Russ, Alissa L. / Saleem, Jason J. / Justice, Connie F. / Hagg, Heather / Woodbridge, Peter A. / Doebbeling, Bradley N.

Summary: Electronic health record (EHR) systems and health information technology (IT) hold unrealized potential for improving the quality, continuity, and safety of medical care; they can also introduce new gaps in care and present unique challenges for healthcare workers. We conducted 14 key informant, semi-structured interviews at a large Veterans Affairs Medical Center and asked healthcare employees why paper use persists despite a fully implemented EHR. In this investigation, we performed a secondary analysis on interview data to identify characteristics of information technology (IT) that are important to support healthcare workflow. As a result of this study, 17 distinct information characteristics emerged; in this document, we provide detail on five characteristics that were often cited as desirable for workflow but insufficiently supported by health IT: 1) customizable, 2) prioritized, 3) trendable, 4) locatable, and 5) accessible. Results from this study reveal key electronic information characteristics for healthcare workflow and have implications for patient safety and future health IT designs.

Computerized Medication Alerts and Prescriber Mental Models: Observing Routine Patient Care HEALTH CARE / Russ, Alissa L. / Saleem, Jason J. / McManus, M.

Summary: Computerized medication alerts (e.g., drug-drug interactions, drug-allergy interactions), which are intended to protect patient safety, need to match the mental models of medication prescribers in order to aid medication ordering. To maximally protect patient safety, the programmer mental model, system image, and prescriber mental model should work seamlessly together to fully support prescriber decision-making. In this study, we examined prescribing processes in the context of routine patient care to understand how the design of medication alerts can be enhanced for prescribers. We shadowed prescribers, including physicians, pharmacists, and nurse practitioners, across five outpatient primary care clinics at a large Veterans Affairs Medical Center (VAMC). In addition, prescribers were opportunistically interviewed as they ordered mediations via a computerized order entry system and resolved any subsequent medication alerts. This investigation is one of the few to examine medication alerts by directly observing prescribers during patient care. Altogether, 191 medication alerts occurred across 63.5 total hrs of observation, 19 prescribers, and 86 patients during routine patient care tasks. Results reveal problematic system images and mismatches between programmer and prescriber mental models. Findings can help inform medication alert redesigns, which may promote safer, more effective prescribing practices.

Medical Informatics: What contributions can human factors make? HEALTH CARE / Smith, Michael W. / Russ, Alissa L. Proceedings of the Human Factors and Ergonomics Society 53rd Annual Meeting 2009-10-19 v.53 p.660-663

Link to HFES Digital Content

Summary: Healthcare is arguably the most complex of the complex, sociotechnical systems studied by the human factors community. This complexity only looks to increase over the next five years as massive changes in how care is delivered and reimbursed are already underway. Not the least of these changes is the not-so-subtle introduction of medical informatics and their corresponding ripple effects on how roles are designed, how work is coordinated, how primary and more distant personnel are impacted, and how power is allocated among groups. Much of the activity in medical informatics is conducted without representation by the human factors community, or even knowledge of what the human factors community can contribute other than usability testing methods. In this panel, a group of leading human factors researchers will provide a range of perspectives to the question: What contributions can human factors make to medical informatics based upon recent cutting-edge research and reflection on past experiences.

Paper Use with the Electronic Medical Record: An Important Supplement or Negative Circumvention HEALTH CARE: HC1 - Health Information Technologies and Human Factors / Saleem, Jason J. / Russ, Alissa L. / Justice, Connie F. / Hagg, Heather / Woodbridge, Peter A. / Doebbeling, Bradley N.

Summary: Healthcare organizations are increasingly implementing electronic medical records (EMRs) and other related health information technology (IT). Even in institutions which have long adopted these computerized systems, there are still instances where employees rely on paper to complete their work. The use of paper suggests that parts of the EMR may not be sufficiently designed to support clinicians and their work processes. To understand the use of paper-based alternatives, we conducted 14 key-informant interviews in a large Veterans Affairs Medical Center (VAMC), with a fully implemented EMR. We found nine distinct categories of paper-based workarounds to the use of the EMR. In several cases, paper served as an important tool and assisted healthcare employees in their work. In other cases, paper use circumvented the intended EMR design, introduced potential gaps in documentation, and generated possible paths to medical error. We discuss implications of these findings for EMR design and implementation.
