Dale Green Talks Future Role of Informatics in Healthcare at Recent Workshop

It’s no secret that the United States is struggling to figure out how to deliver effective, affordable healthcare. The U.S. spends $3.2 trillion on health services, 18 percent of its GDP, but it still ranks 31st in health outcomes among developed nations.

“Health informatics is positioned to be a solution,” said Dr. Dale Green, associate professor of health policy and management and Health Informatics Institute associate director at UGA’s College of Public Health. Green worked for years as a board-certified physician in the Athens area, eventually specializing in clinical informatics.

Green participated in a panel discussion of the needs and uses of informatics at a half-day workshop, “Advancing Informatics in Government and Industry,” hosted by the University of Georgia on December 1. The event aimed to promote discussion of how academia, industry and government can work together to address critical challenges in cybersecurity, data analytics and data science.

The healthcare industry has adapted to major changes in health data reporting, mostly incentivized by federal organizations like the Centers for Medicare & Medicaid Services. But this limited form of clinical informatics is just the tip of the iceberg in health informatics.

“The problem with informatics as a discipline is that it has a different definition depending on who you ask, but generally I want to bring the human element to the technology,” said Green.

In healthcare, most data sources are points of transaction. The insurance codes associated with medical billing are a common example. When information is attached only to payment types and amounts, the context of that information can get lost, says Green.

The reasons why a person comes to interact with the healthcare system, often related to lifestyle, are questions informatics can help answer. Data from smartphones and health devices like FitBits can shape our understanding of the behaviors that lead to positive or negative health outcomes.

Green cautions, however, that constant data sharing carries the risk of privacy loss. Issues related to security and privacy have become barriers to adopting informatics technologies across industries.

“Changes in healthcare in particular are slow,” said Green. “They are people-driven.”

Healthcare providers need to be trained on how to best use this data, he adds. A lot of data is only as good as how it is applied. Predictive modeling and risk stratification are two areas where data is already improving care. Health services utilization is another.

“As a provider, how can I help a patient use X or Y service,” said Green. “That’s where we go next.”

Final HII seminar to discuss how deep learning can improve public health surveillance

Google uses it. Netflix uses it. It’s why these systems seem to know you and what you want to search for or watch. Deep learning is a type of machine learning model that can take in large amounts of data and use it to interpret new data as a person might, even predicting behavior. It’s been described as cutting edge of the cutting edge of artificial intelligence, and deep learning can play a crucial role in improving how public health informatics can use data to improve health and prevent disease.

In the final Health Informatics Institute seminar of the fall semester, the CDC’s Scott Lee will “Deep Learning Applied to Public Health Surveillance: Two Case Studies and an Overview of the Current State of the Art” on December 7th at 12:00 p.m. in 235 Russell Hall on the Health Sciences Campus.

Scott Lee is a statistician in the Center for Surveillance, Epidemiology, and Laboratory Services at the Centers for Disease Control and Prevention in Atlanta. His current work focuses on the application of contemporary machine learning models to problems in public health and biomedical informatics. He also has interests in experimental design and global health. He is a graduate of UGA, having received his PhD in linguistics in 2014.

How can GIS data improve health?

The third in the Health Informatics Institute’s Seminar Series features the University of Georgia’s Lan Mu discuss how geographic information system (GIS) methods can be used to improve public health. GIS  is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data, and its uses in the age of informatics is invaluable.

Join us on November 2 at 12:00 p.m. in room 241 Russell Hall on the Health Sciences Campus for Dr. Mu’s presentation entitled, “GIScience for Health and the Environment: Working with data from Social and Physical Environments to Social Media.”

Mu, Lan is a professor of geography at the University of Georgia.  Her research interests include GIScience for health and the environment, spatial analysis and modeling, computational geometry, cartography and geovisualization.  She also serves as the program coordinator of UGA’s undergraduate and graduate GIScience Certificate Programs.     

HII Seminar to Feature Talk on Big Data and Health

There is invaluable information health professionals can learn from the devices most of us interact with almost every hour of the day, but gathering and translating that data from our cell phones and FitBits into knowledge we can use presents a challenge. To discuss how to tackle that challenge, the second Health Informatics Institute seminar of the 2017 – 2018 series welcomes James M. Regh, a leading expert in gathering massive amounts of data from mobile and wearable devices.

Join us on October 5th, in room 241 Russell Hall, Health Sciences Campus, at 12:00 p.m. to hear Dr. Regh “Big Data in Behavioral Medicine.”

Dr. Rehg is a Professor in the School of Interactive Computing at the Georgia Institute of Technology, where he is Director of the Center for Behavioral Imaging and co-Director of the Center for Health Analytics and Informatics (CHAI) and the Computational Perception Lab (CPL). He received his Ph.D. from CMU in 1995 and worked at the Cambridge Research Lab of DEC (and then Compaq) from 1995-2001, where he managed the computer vision research group. He received an NSF CAREER award in 2001 and a Raytheon Faculty Fellowship from Georgia Tech in 2005. He and his students have received best student paper awards at ICML 2005, BMVC 2010, Mobihealth 2014, and Face and Gesture 2015, and a 2013 Method of the Year Award from the journal Nature Methods.

Dr. Rehg serves on the Editorial Board of the Intl. J. of Computer Vision, and he served as the Program co-Chair for ACCV 2012 and General co-Chair for CVPR 2009, and is serving as Program co-Chair for CVPR 2017. He has authored more than 100 peer-reviewed scientific papers and holds 25 issued US patents. His research interests include computer vision, machine learning, robot perception and mobile health. Dr. Rehg was the lead PI on an NSF Expedition to develop the science and technology of Behavioral Imaging, the measurement and analysis of social and communicative behavior using multi-modal sensing, with applications to developmental disorders such as autism. He is currently the Deputy Director of the NIH Center of Excellence on Mobile Sensor Data-to-Knowledge (MD2K), which is developing novel on-body sensing and predictive analytics for improving health outcomes.
