Title: Who’s Tool is it Anyway: Engaging Clinicians and Patients as Experts when Creating Novel Healthcare Technologies 

Presenter: Megan Hofmann, PhD, Assistant Professor, Khoury College of Computer Sciences, Northeastern University 

watch this presentation

Abstract: As more complex computing tools work their way into healthcare practice, clinicians and patients become reliant on black boxes that determine their outcomes. When these new technologies fail to improve patient care or have dangerous unforeseen consequences, clinicians are held responsible for the limitations of systems they may not readily understand. One approach is to build explainable systems so clinicians can interpret the outcomes of tools after the fact. But at this point, the harm may already be done. In this talk, we discuss a different approach to explainable software where clinicians and patients alike are involved in the development of healthcare tools as first-order experts. The goal of this approach is to remove the shroud of technical mysticism from these black boxes and produce software that both clinicians and their patients can understand and fully control. We will discuss this approach across three case studies exploring different emerging technologies in healthcare.

Title: Understanding the Disability Community’s Needs for Communicating with Social and Caregiving Networks 

Presenter: Rupa S. Valdez, PhD, MS, Professor, Public Health Sciences & Systems and Information Engineering, University of Virginia

Watch This Presentation

Abstract: Two empirical studies conducted in partnership with the disability community will be presented. Both studies present an in depth needs assessment to be used as a foundation for creating informatics tools responsive to the disability community’s needs. In the context of these studies, we have employed a range of methods including interviews, focus groups, task analysis, participatory design sessions, and usability testing. In the first study, supported by the Agency for Healthcare Research and Quality, we engaged with adults living with physical, cognitive, sensory, and mental health related disabilities to understand how best to design informatics tools supporting communication of health information among disabled adults and members of their social networks. In the second study, funded by the National Institutes of Health, we engaged with parents of children with medical complexity to understand the need for informatics tools that support communication and coordination with the child’s caregiving network. At the conclusion of this talk, I will present a framework which synthesizes lessons learned about engaging in informatics research with the disability community across these and other empirical studies conducted by our team.

Bio: My research focuses on understanding and designing solutions to support the ways in which people manage health at home and in the community. I draw on methods from multiple disciplines including human factors engineering, cultural anthropology, and health informatics, among others. This work encompasses participatory and co-design approaches and attends to the ways in which social networks, physical environment, community resources, and information technology shape patient experiences. I am particularly interested in how health is managed among marginalized populations, including racial/ethnic minorities, people with disabilities, and people living in under-resourced settings. A complementary research interest is in methodological development for research and teaching in this space. I have testified before Congress on the topic of bridging health equity gaps for people with disabilities and chronic conditions. My editorial appointments include serving as Associate Editor for Ergonomics, the Journal of American Medical Informatics Association Open, and Human Factors in Healthcare. Among other appointments, I serve on the Board of Directors for the American Association of People with Disabilities and for the American Health Information Management Association Foundation. I also serve on PCORI’s Patient Engagement Advisory Panel and the National Committee for Quality Assurance’s Health Equity Expert Work Group. I am also the Founder and President of the Blue Trunk Foundation.

Title: On Being an Outlier in a World that Worships Optimization 

Presenter: Rua Williams, Assistant Professor, User Experience Design, Purdue University 

Watch This Presentation

Abstract: We often mistake the threat of “AI” as a threat for the future, because so many of the promises are pitched to us as something exciting “just over the horizon.” Unfortunately, algorithms are already used in our financial, judicial, and medical systems. In medicine, as dictated by risk/benefit/profit calculations, these “Algorithmic Inferences” often lead decision-makers to deny care to people because of their classification as disabled, thus accelerating their deaths. The argument is often that these adverse consequences are unintended exceptions. What would it mean to privilege the outlier? What if we used “AI” to find the pruning mechanism and dismantle it?

Bio: Rua M. Williams is an Assistant Professor in the User Experience Design program at Purdue University. They are a Just Tech Fellow with the Social Science Research Council. They study interactions between technology design, computing research practices, and Disability Justice. Common approaches to technology and service design for marginalized people tend to naturalize existing inequities, exacerbating injustice even while they attempt to ameliorate it. Dr. Williams deploys Feminist and Anti-Racist approaches to Technoscience, Critical disability Studies, and Science and Technology Studies in the design and evaluation of technological systems to simultaneously illustrate injustice in technology as well as marginalized users’ own practices of resistance through those same technologies.

Title: Post-growth HCI

Presenter: Neha Kumar, Associate Professor, Georgia Tech

At speaker’s request, this presentation was not recorded

Abstract: Human–Computer Interaction (HCI) researchers have increasingly been questioning computing’s engagement with unsustainable and unjust economic growth, pushing for identifying alternatives. Incorporating degrowth, post-development, and steady-state approaches, post-growth philosophy offers an alternative not rooted in growth but in improving quality of life. It recommends an equitable reduction in resource use through sensible distributive practices where fulfillment is based on values including solidarity, cooperation, care, social justice, and localized development. This brand new TOCHI paper—coauthored with Vishal Sharma and Bonnie Nardi—that I will present describes opportunities for HCI to take a post-growth orientation in research, design, and practice to reimagine the design of sociotechnical systems toward advancing sustainable, just, and humane futures. We aim for the critiques, concerns, and recommendations offered by post-growth to be integrated into transformative HCI practices for technology-mediated change.

Bio: Neha Kumar is an associate professor at Georgia Tech, where she works at the intersection of human-centered computing and global sustainable development, with a focus on infrastructuring care and engaging community.

Title: Improving Prediction of 30-day Hospital Readmission for Patients with Heart Failure through the Integration of Neighborhood-Level Measures  Presenter: Joyce Ho, Assistant Professor in the Department of Computer Science, Emory University Watch this Presentation Abstract: Heart failure is the most common cause of cardiovascular hospitalization in elderly patients. Even with recent therapeutic improvements, approximately 20% of patients are readmitted to the hospital within 30 days. Moreover, there are persistent racial disparities in heart failure outcomes. The neighborhood environment has emerged as an understudied and under-utilizer driver of readmission. Yet such information is not commonly collected in electronic health records and existing deprivation indices may not fully capture the neighborhood factors. In this talk, I will present our work on the integration of social media, location-based services, and air quality data to enhance our neighborhood understanding of 30-day readmission for heart failure. Bio: Joyce Ho is an Associate Professor in the Computer Science Department at Emory University. She received her Ph.D. in Electrical and Computer Engineering from the University of Texas at Austin, and an M.A. and B.S. in Electrical Engineering and Computer Science from MIT. Her research focuses on the development of novel machine learning algorithms to address problems in healthcare such as identifying patient subgroups or phenotypes, integrating new streams of data, fusing different modalities of data (e.g., structured medical codes and unstructured text), and dealing with conflicting expert annotations. Her work has been supported by the National Science Foundation (including a CAREER award), National Institute of Health, Robert Wood Johnson Foundation, and Johnson and Johnson.

Speakers: Krystal Tsosie and Keolu Fox

Title: #DATABACK: Indigenous Genomic Data Justice for Indigenous Peoples 

Watch This Presentation

Abstract: Despite over a decade of efforts to increase diversity in genomic datasets, Indigenous peoples still constitute less than 1% of total representation. The answer, however, is not simply to recruit more Indigenous peoples because defaulting to old, problematic norms of broad consent can recreate cycles of data exploitation and extraction that benefit Indigenous peoples last. To move forward, we need to rethink data equity approaches that center principles of Indigenous genomic data sovereignty, which means employing new techniques in blockchaining and federated learning in addition to Indigenous-led bio-databanks. Hence, Drs. Tsosie and Fox are advocating for an Indigenous data justice approach that is truly responsive to genomic medicine and precision health innovation.

Bios: Krystal Tsosie, PHD, MPH, MA is an Indigenous (Diné/Navajo Nation) geneticist-bioethicist at Arizona State University’s School of Life Sciences and Center for Biology and Society. She co-founded the Native BioData Consortium, the first US Indigenous-led biobank and 501c3 nonprofit research institution. Much of her current research centers on ethical engagement with Indigenous communities in precision health through genetic epidemiology, public health, and computational approaches. She is also increasingly exploring machine learning approaches and using digital data tools to operationalize Indigenous genomic data sovereignty to foster Indigenous-led data solutions and build Tribal Nations’ capacity in technology, health, education, and local data economies.

Keolu Fox is the first Kānaka Maoli (Native Hawaiian) to receive a doctorate in genome sciences, and is an assistant professor at the University of California, San Diego, affiliated with the Department of Anthropology, the Global Health Program, the Halıcıoğlu Data Science Institute, the Climate Action Lab, the Design Lab, and the Indigenous Futures Institute. His work focuses on the connection between raw data as a resource and the emerging value of genomic health data from Indigenous communities. He has experience designing and engineering genome sequencing and editing technologies, and a decade of grassroots experience working with Indigenous partners to advance precision medicine. As an ENRICH Global Chair, Keolu will build a library for Indigenous health data in partnership with Indigenous communities. He will pilot a platform that will enable collecting and protecting Indigenous health data using Indigenous Data Sovereignty (IDS) principles, which provides a framework for allowing Indigenous communities themselves to manage and benefit from their own data. Ultimately, he hopes to create a replicable standard for Indigenous data sovereignty.

Title: Participatory Approaches to Health AI    

Per the speaker’s request, this session was not recorded.

Abstract: Advances in computing technology continue to offer us new insights about our health. As mutually reinforcing trends make the use of wearable and mobile devices routine, we now collect personal, health-related data at an unprecedented scale. Meanwhile, the use of deep-learning-based health screening technologies changes relationships between caregivers and care recipients, with multitudinous implications for equity, privacy, safety, and trust. How can researchers take inclusive and responsible approaches to envisioning solutions, training data, and deploying ML/AI-driven solutions? Who should be involved in decisions about how to use ML/AI in digital health and well-being solutions, and even what solutions matter in the first place? 

In this talk, I will discuss participatory approaches to designing digital health and well-being technologies with impacted communities. Starting with field studies in clinics exploring how people navigated use of a deployed, diagnostic AI system, and moving onto lessons learned from an international study of how people with marginalized health needs navigate aspects of their health care, I will highlight the importance of taking participatory approaches to technology design, development, and evaluation.

Title: Transforming the Health of Communities through Innovations in Social Computing

Speaker: Dr. Andrea Grimes Parker, Associate Professor at Georgia Tech 

Watch This Presentation

Abstract: Digital health research—the investigation of how technology can be designed to support wellbeing—has exploded in recent years. Much of this innovation has stemmed from advances in the fields of human-computer interaction and artificial intelligence. A growing segment of this work is examining how information and communication technologies (ICTs) can be used to achieve health equity, that is, fair opportunities for all people to live a healthy life. Such advances are sorely needed, as there exist large disparities in morbidity and mortality across population groups. These disparities are due in large part to social determinants of health, that is, social, physical, and economic conditions that disproportionately inhibit wellbeing in populations such as low-socioeconomic status and racial and ethnic minority groups. 

Despite years of digital health research and commercial innovation, profound health disparities persist. In this talk, I will argue that to reduce health disparities, ICTs must address social determinants of health. Intelligent interfaces have much to offer in this regard, and yet their affordances—such as the ability to deliver personalized health interventions—can also act as pitfalls. For example, a focus on personalized health interventions can lead to the design of interfaces that help individuals engage in behavioral change. While such innovations are important, to achieve health equity there is also a need for complimentary systems that address social relationships. Social ties are a crucial point of focus for digital health research as they can provide meaningful supports for positive health, especially in populations that disproportionately experience barriers to wellbeing

I will offer a vision for digital health equity research in which interactive and intelligent systems are designed to help people build, enrich, and engage social relationships that support wellbeing. By expanding the focus from individual to social change, there is tremendous opportunity to create disruptive interventions that catalyze and sustain population health improvements.

Title: Disability accessibility and fairness in Artificial Intelligence (AI) 

Speaker: Cynthia Bennett, PhD, Senior Research Scientist at Google’s People + AI Research Group 

Watch this presentation

Abstract: Artificial intelligence (AI) promises to automate and scale solutions to perennial accessibility challenges (e.g., generating image descriptions for blind users). However, research shows that AI-bias disproportionately impacts people already marginalized based on their race, gender, or disabilities, raising questions about potential impacts in addition to AI’s promise. In this talk I will overview broad concerns at the intersection of AI, disability, and accessibility. I will then share details about one project in this research space that led to guidance on human and AI-generated image descriptions that account for subjective and potentially sensitive descriptors around race, gender, and disability of people in images.

Title: Standardizing the Unstandardizable: The Case of Sex and Gender 

Watch This Presentation

Abstract: In 2015, notice number NOT-OD-15-102 was released by the National Institutes of Health. The notice specified “consideration of sex as a biological variable” (SABV), requiring submission of information regarding this new construct from 2016 onward. However, despite this imperative explicitly citing enhancement of reproducibility, it did not lay out any conceptualization of what SABV meant, in non-human animal or human contexts, and it relied heavily on binarist and gender essentialist assumptions, which have ultimately confused the situation further. This confusion has led to SABV being co-opted by transphobic and intersexphobic organizations and individuals, while not necessarily impacting reproducibility. Why are sex and gender such complicated variables to consider? How did these constructs come to exist within the purview of scientific analysis? And what work is being done to untangle the current situation? This talk will aim to discuss these questions, while also considering the deeper ideologies underlying current scientific research and sociopolitical agendas, and how they affect effective modeling of sex and gender constructs in informatics and beyond.

Title: Algorithmic bias and data platforms  

Watch This Presentation

Abstract: We’re increasingly aware of the many ways that algorithms can encode and scale up racial bias. When designed with careful attention to label choice, algorithms can also be used to counter biases present in the health care system and ingrained in medical knowledge. To do so effectively, researchers and product developers must have access to platforms on which they can access health data for the benefit of patients and society.

Title: Achieving TechQuity

(seminar was not recorded at the request of the Dr. Clark)

Abstract: Open discussions of social justice and health inequities may be an uncommon focus within information technology science, business, and health care delivery partnerships. However, the COVID-19 pandemic—which disproportionately affected Black, indigenous, and people of color—has reinforced the need to examine and define roles that technology partners should play to lead anti-racism efforts through our work. In this hour, we will discuss the imperative to prioritize TechQuity, and addressing social contexts in the implementation of AI and other technologies.

Talk title: Are phenotyping algorithms fair for underrepresented minorities within older adults? 

Watch The Presentation Here

Abstract: The widespread adoption of machine learning (ML) algorithms for risk-stratification has unearthed plenty of cases of racial/ethnic biases within algorithms. When built without careful weightage and bias-proofing, ML algorithms can give wrong recommendations, thereby worsening health disparities faced by communities of color. Biases within electronic phenotyping algorithms are largely unexplored. In this work, we look at probabilistic phenotyping algorithms for clinical conditions common in vulnerable older adults: dementia, frailty, mild cognitive impairment, Alzheimer’s disease, and Parkinson’s disease. We created an experimental framework to explore racial/ethnic biases within a single healthcare system, Stanford Health Care, to fully evaluate the performance of such algorithms under different ethnicity distributions, allowing us to identify which algorithms may be biased and under what conditions. We demonstrate that these algorithms have performance (precision, recall, accuracy) variations anywhere between 3 to 30% across ethnic populations; even when not using ethnicity as an input variable. In over 1,200 model evaluations, we have identified patterns that indicate which phenotype algorithms are more susceptible to exhibiting bias for certain ethnic groups. Lastly, we present recommendations for how to discover and potentially fix these biases in the context of the five phenotypes selected for this assessment.

Title: Multimorbidity Patterns Across Race/Ethnicity Stratified by Age and Obesity: A Cross-sectional Study of a National US Sample  

(Due to the ongoing research, this seminar was not recorded)

Objectives: The objective of our study is to assess differences in prevalence of multimorbidity by race. 

Methods: We applied the FP-growth algorithm on middle-aged and elderly cohorts stratified by race, age, and obesity level. We used 2016-2017 data from the Cerner HealthFacts® Electronic Health Record data warehouse.  We identified disease combinations that are shared by all races/ethnicities, those shared by some, and those that are unique to one group for each age/obesity level. 

Results: Our findings demonstrate that even after controlling for age and obesity, there are differences in multimorbidity prevalence across races. There are multimorbidity combinations distinct to some racial groups—many of which are understudied. Some multimorbidities are shared by some but not all races. African Americans presented with the most distinct multimorbidities at an earlier age. 

Discussion: The identification of prevalent multimorbidity combinations amongst subpopulations provides information specific to their unique clinical needs. 

Title: Identifying and Leveraging Public Data Sources with Social Determinants of Health Information for Population Health Informatics Research  Watch The Presentation Here Abstract: Social determinants of health (SDOH) account for many health inequities. Data sources traditionally used in informatics research often lack SDOH, and, when available, SDOH may be difficult to leverage given it’s lack of specificity and lack of structured information. In this presentation, I will share the initial phases of work that we are doing around leveraging SDoH data – for health equity research – addressing some of the informatics challenges leveraging social determinants of health data to inform population health or inform health services research. I will discuss a case study using a machine learning clustering algorithm to uncover region-specific sociodemographic features and disease-risk prevalence correlated with COVID-19 mortality during the early accelerated phase of community spread.
Title: Toward health justice in informatics: a community-based, intersectional approach to HIV informatics intervention development 
Abstract: June 2021 will mark 40 years since the first cases of what would later become known as acquired immunodeficiency syndrome (AIDS) were reported in the United States. Despite groundbreaking biomedical advancements in HIV prevention and treatment, the HIV/AIDS epidemic continues to disproportionately affect sexual and gender minority communities of color. In this talk, I will discuss the development of an HIV informatics intervention aimed at reducing inequities in linkage and retention in HIV prevention and care among sexual minority Black men in the South. I will present strategies for leveraging informatics to achieve health justice in the fight to end AIDS.
