Biomedical Informatics Approaches to Study Asthma
Abstract: Various efforts are underway to gather a wide range of patient-specific data, including symptoms, medication utilization, environmental exposures, and genomics, with the expectation that collection and integration of this data will enable personalized medicine. This talk will illustrate different approaches taken specifically to study asthma, ranging from the use of electronic-health record (EHR)-derived data to the analysis of transcriptomic data. 
Bio: Dr. Himes’ research focuses on gaining insights into asthma pathogenesis and treatment using biomedical informatics approaches. She has performed genome-wide association studies of asthma and related traits as a lead investigator and as part of large collaborations. She has used probabilistic graphical models to find genetic association networks and designed a computational algorithm to search through large datasets for optimal predictors of a phenotype. She has identified and characterized subjects for asthma genomics studies using patient-derived data from electronic medical records. Most recently, she has used RNA-Seq to study human airway smooth muscle cell response to asthma medications, vitamin D, and to identify differences in response between fatal asthma patients vs. individuals without asthma.

Calibration of Predictive Models for Clinical Decision Making
Abstract: A large number of clinical decision support applications rely on predictive models for binary outcomes. These models usually estimate the probability for an outcome of interest (e.g., probability of readmission to the hospital within a time window). Given that clinical decisions rely on these probability estimates, it is critical that they be well calibrated (i.e., the estimates are sufficiently close to the true underlying probability that the event will occur). Surprisingly, the evaluation of predictive models rarely includes an assessment of calibration, while essentially all include an assessment of discrimination (e.g., AUC: areas under the ROC curve). I will describe the perils of using non-calibrated models for making clinical and administrative decisions, describe various methods to recalibrate existing models or to include calibration in model development algorithms.

Improving Patient-Centered Communication in Primary Care
Abstract: Ming Tai-Seale, PhD, MPH will discuss the design and plan of a $5.8 million, multi-site study funded by the Patient-Centered Outcomes Research Institute (PCORI): “Improving Patient-Centered Communication in Primary Care: A Cluster Randomized Controlled Trial of the Comparative Effectiveness of Three Interventions.” To rigorously answer the question of which approach is more effective and more scalable in promoting patient-centered communication, it does a head-to-head comparison of three different interventions: Open Communication High Touch, Open Communication High Tech, and ASK (a preexisting simple intervention). The study will have three arms, with twenty one clinics in three health care delivery systems, including UCSD Health.  
Bio: Ming Tai-Seale, PhD, MPH, Professor of Family Medicine and Public Health, UCSD School of Medicine, and Director of Outcomes Analysis at UCSD Health IS Department, is a health economist and health services researcher. Tai-Seale examines the impact of financial and organizational incentives on health services delivery and patient outcomes. She collaborates with physicians, patients, clinic leaders, and researchers from multiple disciplinary backgrounds to study patient-physician communication, primary care transformation, and how physicians allocate time and effort in office visits by taking a detailed look at patient-physician communication captured by video- or audio-recordings and the access log of EpicCare. A paper resulting from analyses of EpicCare Logs was the second most read paper in Health Affairs in 2017.

February 23, 2018 - Dr. Eric Hekler
Using Mobile Health Technologies to Affect Behavior Change
Abstract: Three emerging trends are disrupting current models for promoting health and treating illness: 1) unsustainable growth in the complexity and cost of healthcare & health promotion; 2) a movement towards more human-centered and personalized strategies for fostering health and treating disease; and 3) an explosion in information, communication, and computing technologies and the “big data” these systems produce. There is great excitement about the possibility of leveraging the second and third trends to realize the vision of a human-centered, preventive, cost-effective health system and corresponding “Culture of Health” but myriad technical and, perhaps more importantly, cultural challenges need to be overcome. PURPOSE: The purpose of this presentation is to present conceptual work on an “agile” scientific process for creating, optimizing, and repurposing useful and usable behavior change interventions, coupled with empirical research related to more personalized and precise digital health interventions focused on behavior change that can help to enable this broader vision. OUTLINE: The talk will begin with a brief summary on how the “agile science” process is an alternative way of conceptualizing evidence-based practice for behavior change that acknowledges the above three trends. Following this, key empirical work will be presented that with regard to the use of control systems engineering for behavior change, just-in-time adaptive interventions, and supporting individuals in conducting their own “self-experiments” for behavior change.  I will conclude with examples of ongoing projects that I’m involved in with partners in academia, industry, clinical practice, and patient-lead scientists, as illustrations of the many plausible use-cases of agile science.  
Bio: Eric Hekler, PhD, is an Associate Professor in the Department of Family Medicine and Public Health at UCSD. He is also Director of the Center for Wireless & Population Health Systems and faculty member of the Design Lab at UCSD.

Implementation and evaluation of clinical informatics applications: journey of “AWARE” and “Sepsis Sniffer”
Abstract: Development and implementation of sepsis alert systems is challenging, particularly outside the monitored intensive care unit (ICU) setting. Barriers to wider use of sepsis alerts include evolving clinical definitions of sepsis, information overload, and alert fatigue, due to suboptimal alert performance. Outside the ICU, barriers include differences in health care delivery models, charting behaviors, and availability of electronic data. Current evidence does not support routine use of sepsis alert systems in clinical practice. Continuous improvement in the afferent and efferent aspects will help translate theoretic advantages into measurable patient benefit.

Health Information Exchange: What’s taking so long, what are the real barriers and why won’t the fax machine just die?
Abstract: 
Easy access to clinical information that travels with the patient wherever she seeks care was supposed to revolutionize medicine and provide dramatic cost savings to the US Health System.  Even as most health systems and provider offices have successfully adopted EHR technology and report sharing data with outside organizations (see graph), interoperability and open health information exchange for the purpose of treatment and care coordination (forget about research) still seems like a pipe dream to many providers and patients.  Let’s find out why…  
Bio: Dr. Matthew Eisenberg joined Stanford Health Care as a Medical Informatics Director for Analytics and Innovation in February 2013.  His work at Stanford Health Care focuses on interoperability – specifically health information exchange, quality and regulatory reporting, population health and analytics for improvement.  Stanford Health Care is a HIMSS Stage 7 certified hospital and outpatient organization.  Prior to joining Stanford Health Care, he was the Medical Vice President for Clinical Informatics at MultiCare Health System in Tacoma, Washington.
Dr. Eisenberg is board certified in Pediatrics and Clinical Informatics.  He is Clinical Assistant Professor (Affiliated) in the Stanford Center for Biomedical Informatics Research within Stanford University’s School of Medicine.  He is currently a member of the eHealth Exchange Coordinating Committee, the Sequoia Project Board of Directors, the Carequality Advisory Council and the Chair of the Epic Care Everywhere Governing Council.  He serves as the Associate Program Director for the Stanford Clinical Informatics Fellowship Program.  He is a member of the American Academy of Pediatrics Council on Clinical Information Technology, the AMIA Clinical Decision Support Workgroup, the American Association for Physician Leadership, the Association of Medical Directors of Information Services and HIMSS.
After completing medical school at the University of California, San Francisco and pediatric residency at Boston Children’s, Dr. Eisenberg began his private practice career in general pediatrics at The Palo Alto Medical Clinic back in 1990 when medical records were still on papyrus.  After moving to the Pacific Northwest he joined the Virginia Mason Medical Center in 1996.  He completed a fellowship training program in Evidence Based Pediatrics at the University of Washington in 1998.  In 2003 Dr. Eisenberg joined Seattle Children’s as an informatics physician and began work on their acute care CPOE implementation using a Cerner Millennium EMR platform.  His work focused initially on order set development and physician training and he expanded his informatics role as Seattle Children’s implemented their ambulatory EMR with CPOE. During his tenure at Seattle Children’s, Dr. Eisenberg was an active member of the Cerner Physician Reference Group.  He completed the Oregon Health and Science University AMIA 10 x 10 training course in 2006.  In 2007 Dr. Eisenberg joined MultiCare Health System, an integrated delivery system in Tacoma, WA as their new Medical Director of Information Services.  MultiCare was an early adopter of Epic systems software dating back to 1998.  After Dr. Eisenberg’s arrival, MultiCare extended their electronic health record across the enterprise to include four of five hospitals, implemented bedside bar coding, installed an integrated enterprise content management system and pushed the envelope of health information exchange as an early participant in the nationwide health information network (NwHIN) via the Virtual Lifetime Electronic Record (VLER) project.  In 2009, MultiCare was awarded the HIMSS Davies Organizational Award.
