        Research Interests

        Jennifer Tjia, MD, MSCE is Associate Professor of Medicine at the University of Massachusetts Medical School and a Research Associate at the Meyers Primary Care Institute. Dr. Tjia’s research interests include health services research and pharmacoepidemiology. Her interests focus on optimizing the use of chronic prescription medication by older adults, particularly in nursing home residents with advanced dementia and near the end-of-life. She has been awarded a K08 Mentored Clinical Scientist Career Development Grant from the National Institute on Aging to study the health outcomes associated with differences in prescription drug coverage for older adults and an R21 from AHRQ to use secondary administrative Medicare data to study medication optimization in advanced dementia. She has been co-investigator on multiple federal grants including AHRQ “Improving Posthospital Medication Management of Older Adults through Health IT” & “Using HIT to Improve Transitions of Complex Elderly Patients from SNF to Home”, and “Risk Informed Intervention to Improve Ambulatory Drug Monitoring and Safety”. She is co-author of “Appropriate Approach to Prescribing” in the 6th edition of Hazzard’s Principles of Geriatric Medicine and Gerontology. She has co-directed “Design and Observational Studies and Clinical Trials” course in the Masters of Science in Clinical Investigation Program.
