Baker, MD, MPH, is a Professor of Medicine, FSM chief of General Internal Medicine and associate director of FSM’s Institute for Healthcare Studies and the director of the REACH Practice Based Research Network. Dr. Baker is a nationally recognized clinical investigator in health services research including studies of health care access, racial/ethnic disparities, health communication, health literacy, and quality of care for chronic diseases.  He is experienced in community-based research, e.g., leading the Literacy and Health of Medicare Managed Care Enrollees, which interviewed more than 3000 patients in their homes and tracked mortality. Since joining NU in 2001, he has led efforts to use Electronic Health Record (EHR) data systems for recruitment into clinical studies and for quality measurement/improvement. This work has been conducted in both the Northwestern Medical Faculty Foundation (NMFF) General Internal Medicine (GIM) clinic and in community-based medical practices. With the Center for Outcomes Research and Evaluation at ENH, he has established electronic quality measurement systems, partnering with the American Medical Association and the Center for Medicare and Medicaid Services. He was the first in the US to analyze the validity of these measures. He leads a diabetes quality improvement project being done in federally qualified health centers (FQHCs) in Chicago.  He also collaborates with community practices on a NIA-funded study of racial/ethnic differences in health status measures, which has recruited greater than 400 patients, relying heavily on EHR data to identify eligible patients.
