Research overview

Research on health informatics at Group Health focuses on developing and using health information technology (IT) to transform health care delivery. By testing new paradigms of care that provide more opportunities to engage patients outside of in-person visits, this research is supplying valuable evidence that is helping shape federal policy and guiding innovative redesign of health care.

“Our goal is to understand how to make health IT practical in ways that directly engage patients and providers,” explained Group Health Research Institute (GHRI) Associate Investigator and lead health IT researcher James Ralston, MD, MPH. “We want to find ways to use information technologies to support patients and providers together, both inside and outside the office.”

Integral to this support is designing technologies that are user-friendly and meet the needs of both patients and providers. By applying human-centered methods, new Assistant Investigator Andrea Hartzler, PhD, informs the design of health IT by focusing on needs, use, and usability through direct input from users.

With health IT playing a pivotal role in health care reform, understanding how to maximize its effectiveness has never been more important. Dr. Ralston’s research on secure messaging between patients and providers showed that it increased patient satisfaction with care. His team’s findings influenced Group Health’s organization-wide rollout of the patient-centered medical home—and were later cited in federal rules requiring hospitals and health care professionals to use secure messaging to receive incentive payments for meaningful use of electronic health records.

Other areas of focus for the research include:

  • using Web-based care and a patient-shared electronic medical record to improve care for chronic illnesses, such as depression, diabetes, and heart disease;
  • understanding the effects of new technologies such as OpenNotes, which gives patients access to notes that their doctors write during office visits (see 2012 news release);
  • testing “natural language processing” (NLP) to target mentions of specific words and phrases in electronic medical records and supplement skilled chart abstraction—providing faster access to “big data,” according to Clinical Data Scientist David Carrell, PhD, who leads GHRI’s work on NLP (see feature story: ‘Teaching’ computers to read doctors’ notes promises gains in research efficiency); and
  • evaluating how well mobile health applications—including Group Health’s award-winning Mobile MyGroupHealth—meet the needs of traditionally underserved populations.

“Our studies on using health IT to improve care are showing that we can achieve better outcomes when we shift care from the doctor’s office to where people live: in their homes—and online,” said Associate Investigator and Group Health Family Physician Beverly B. Green, MD, MPH.
