Abstract: Digital phenotyping is a data collection technique that models the physical and cognitive state of smartphone users based on their usage behaviors for clinical or research purposes. While it automates most of the process, certain types of data still need to be collected from user-facing surveys and tests. This leads to a challenge: How do we motivate the user to keep completing repetitive tasks on an app over a long period? Following a multi-stage design thinking framework, we studied and redesigned mindLAMP, a cross-platform digital phenotyping app, specifically for a research study on dementia risk factors among older adults. After involving users early on to better understand the older adult population and identify potential problems in mindLAMP, we proposed and evaluated a new design – MindJournal – that caters to both this specific research and the unique needs of older adults. Through multiple rounds of engagement with users, we identified key factors that affect older adult’s continued engagement over a long research study. With respect to our redesign, most participants preferred MindJournal over mindLAMP and had a more efficient and satisfactory experience completing three representative tasks on MindJournal. Therefore, NRC and its partners should adopt MindJournal with improved features that leverage older adults’ interest and motivation for consistent and prolonged engagement for their ongoing research.

Abstract: Today’s academic events, particularly academic conferences, have a problem with diversity in both presenters and attendees. To address this issue, various people and groups have created guidelines for improving conference diversity. To support a similar project at UBC, we first interviewed conference organizers on their current struggles with organizing inclusive conferences. We then created a set of design guidelines to aid our development of a UBC-based diverse conference organization toolkit. The content for the toolkit is in development and provided by a UBC committee with the goal of solving the same issue of diversity. We conducted a two-stage card sorting activity to determine a natural structure of the toolkit content. We created a prototype toolkit and conducted user testing to validate its success. As a result, we contributed design guidelines for diversity-related resources, a prototype toolkit for supporting conference organizers in making conferences more diverse, documentation for the prototype, and a set of suggestions for improving the toolkit and its content in the future. User testing of the prototype validates the design and provides feedback for future work.

Abstract: Diseases of the lung have severe consequences both in acute and chronic conditions. As an example, COPD (Chronic Obstructive Pulmonary Disease) is characterized by inflammation of the airways, causing obstruction of airflow. COPD has an almost continuous impact on a person’s quality of life and can lead to hospitalization and a severe decrease in the patient’s quality of life. Given the severe impact on a person’s quality of life and wellbeing, the RADAR (Robot Assisted Digital Auscultation Rendering) group under the University of British Columbia approached the LungSounds@Home team (the authors of this paper) with the goal of facilitating auscultation (gathering of lung sounds) at home by patients. The LungSounds@Home team conducted a set of studies including feasibility tests on existing technologies, expert interviews, literature review, and interviews with elderly individuals’ regarding their experience with technology. The team identified that there is a need for a digital interface that supports regular, at-home, self digital auscultation (SDA) for an elderly (>65 years) COPD population. The team then proposed design guidelines with such a target user group in mind and prototyped an interface for at-home self-auscultation based on the guidelines. To summarize, the contributions of this project are two-fold: (1) design guidelines for an interface that facilitate SDA protocol and is easy to use by elderly individuals and encourages higher adherence; (2) a medium-fidelity prototype of an SDA protocol for use by elderly people with COPD, and validated based on a qualitative study with 8 undergraduate and/or graduate-level students.

V4: Don’t Panic: Reducing Testing-Anxiety Using Last-Minute Interventions in a Synchronous Waiting Room

Abstract: Testing anxiety is a common experience for university students as high-stakes exams remain the norm in higher education. However, research suggests that testing anxiety has a negative impact on testing performance. Because high stakes exams cannot be easily eliminated or erased, researchers have tried to find ways to reduce this anxiety. While strategies during tests or as part of a routine can be effective, these strategies tend to be subject specific or beyond the influence of a classroom experience, respectively. Consequently, this study aims to design an exam waiting room that uses last-minute interventions to reduce student testing anxiety. Through design research including user interviews, creation of personas and conceptual designs, and creating and testing prototypes, we found that uncertainty and fear of not being able to demonstrate their knowledge motivated student anxiety and that students with higher anxiety levels wanted to reduce anxiety symptoms to calm down and focus their mind rather than engage in distractions before a test. Furthermore, we determined that therapeutic exercises such as breathing exercises were effective at reducing anxiety, and that other interventions such as listening to music and viewing exam material reduced stress in some but not all students. We provide further design considerations including rationalization for our design choices in creating a medium-fidelity prototype along with suggestions for further research in designing an exam waiting room.

V5: Managing Infusion Pumps at Vancouver General Hospital

Abstract: Alaris infusion pumps are the most common medical devices that Lower Mainland Biomedical Engineering (LMBME) supports. Despite a utilization rate of only 42%, Vancouver General Hospital (VGH) continues to experience complaints about limited pump availability. This project aims to investigate the factors contributing to this shortage at VGH, in order to reduce its negative consequences and improve pump cleaning and distribution processes. Based on these findings, we identified and evaluated several potential solutions and recommended the one best suited to VGH’s needs. We then developed a plan for implementation and a proof-of-concept interface for the proposed solution. The time-consuming nature of the existing pump management workflow became apparent during our stakeholder meetings with pump cleaning and distribution, nurses, and LMBME. The process of searching for pumps was the most time-consuming step according to our stakeholder groups. Therefore, reducing search time for both soiled and clean pumps is central to addressing the limited availability of infusion pumps. We considered the following three solutions: camera tracking coupled with barcode scanning, passive and active RFID, and an interface built on the existing Alaris Manager System (AMS). We compared and ranked each solution based on initial and ongoing costs, maintenance, implementation, information provided, and usability and did an experiment to assess the impact of each solution on time. When all solutions provided accurate information, we realized around a 25% time reduction to search for soiled pumps, relative to their current pump management workflow. Based on these findings, we concluded that an interface built on their existing AMS represents the most feasible solution given the value it adds at its price point. Besides the proposed implementation plan and a proof-of-concept interface for AMS, evaluations and design iterations will need before the proposed solution can be implemented at VGH.

V6: Virtual Trauma Bay

Abstract: The trauma bay from the Vancouver General Hospital (VGH) is the first point of contact for critically injured patients and it is where patients are resuscitated, stabilized, and provided with definite care. The establishment of trauma systems has effectively reduced in-hospital mortality rates. However, rural and remote areas of British Columbia do not have quick access to trauma care. Delays to definitive care reduces the chances of survival of the patient, bringing about the critical need to move definitive care closer to the scene of injury. Through interviews with paramedics, nurses, and trauma surgeons we identified that difficulties in communication start with the recording of patient information and delayed pre-hospital notification. Due to the critical nature of their job, paramedics may not have time to convey valuable patient information to the hospital prior to arrival, limiting the time available for hospitals to prepare. Hence, to tackle the broad communication problems existing during a trauma activation, we first focused on facilitating pre-hospital notification. We identified key aspects in the workflow of paramedics and charge nurses and designed a system that could potentially replace the current ambulance-to-hospital phone call. We created a low-fidelity prototype interface for a tablet application which paramedics can use to communicate information about the patient to the hospital in a timely fashion, with minimum interruption to their workflow and with the aim of facilitating early trauma team activation. The system provides hospitals with access to a live visual feed of the patient in the back of the ambulance, collected from a ceiling mounted camera. The system was evaluated by our stakeholders through a video demo and a survey. We identified that single button calls and the ability to leave verbal messages to the hospital were perceived as valuable. Further user tests are required to evaluate the value of live video stream.
