Dr. Fairfield is an internist and Physician Scientist at CORE, and Associate Professor of Medicine at Tufts School of Medicine. Her education and training includes an A.B. from Bowdoin College, M.D. from Boston University School of Medicine, and internship and residency at Beth Israel Hospital in Boston. She completed the Harvard Medical School fellowship in General Medicine, earning an M.P.H. and Dr.P.H. in Epidemiology and Nutrition at Harvard School of Public Health. After serving on the faculty at Beth Israel Deaconess Medical Center, Dr. Fairfield joined MMC in 2002.

Dr. Fairfield’s work is at the intersection of health services research, improvement science in health care delivery, and population health. She is the Principal Investigator for the IMPROVE Study (Improving Maine’s Population Health, Research Impact, Outcomes, Value, and Equity through Education). This work includes analyses of large health care claims, medical records, and health behavior datasets to understand patterns of health care and the complex relationships between health care delivery and population health. Active research projects include analyses of variation in care and outcomes of opioid use, malignancies, and cardiovascular disease as they relate to health behaviors. In order to disseminate this work, Dr. Fairfield co-developed a nine-month Certificate in Health Care Improvement with Dr. Peter Bates and The Dartmouth Institute, aimed at training inter-professional teams about these concepts in the context of local reports of care delivery and population health.

She also studies and teaches shared decision making models of care using standardized patients and other methods. Dr. Fairfield currently collaborates on health care quality initiatives through CORE’s partnership with the Center for Performance Improvement at MaineHealth. Her leadership roles include serving as Associate Chair of the Department of Medicine for Research and Quality Improvement and Director of the Division of Healthcare Delivery Science at MMC. She has received research support from the AHRQ, NIH, PCORI, Maine Cancer Foundation, the Informed Medical Decisions Foundation, American Cancer Society, and the Arnold P. Gold Foundation.

In addition to her research and improvement science activities, Dr. Fairfield sees patients and supervises residents in the International Clinic at MMC. She is board certified in Internal Medicine. Dr. Fairfield also volunteers as a primary care provider and Medical Director for the Portland Community Free Clinic.
