Research Interest
Dr. Korytkowski’s research interests focus on improving inpatient and outpatient care and outcomes of people with diabetes. In the outpatient setting, Dr. Korytkowski serves as co-investigator and study physician for the NIH-sponsored Look AHEAD Study which is examining long term cardiovascular outcomes in individuals with type 2 diabetes randomly assigned to intensive versus conventional lifestyle intervention. She is co-investigator on two additional NIH sponsored clinical trials, one investigating interactions between treatment for obstructive sleep apnea (OSA) and diabetes outcomes; and another exploring relationship dynamics in couples affected by diabetes. Previously, she was Diabetology site PI for the Bypass Angioplasty Revascularization Investigation in type 2 diabetes (BARI 2D) that sought to define optimal glucose lowering and cardiovascular intervention strategies for type 2 diabetes complicated by coronary artery disease.
In the inpatient setting, much of Dr. Korytkowski’s work has focused on initiatives that investigate specific glycemic management strategies in hospitalized patients with diabetes, such as those who are hospitalized using insulin pump therapy or who receive enteral nutrition therapy. A recent study is investigating hypoglycemia unawareness in hospitalized patients as a risk for severe hypoglycemia and adverse outcomes.
An additional area of interest that crosses inpatient and outpatient areas is using electronic medical records to investigate patterns of glycemic management and cardiovascular outcomes in diabetes. Because diabetes is a systemic disorder affecting multiple organ systems, Dr. Korytkowski has wide collaborations with investigators in other divisions in the Department of Medicine as well as with other universities.
Clinical Interest
Dr. Korytkowski is a general endocrinologist with particular expertise in the care and management of people with all forms of diabetes, as well as of women with polycystic ovary syndrome and other disorders of androgen excess. As Director of Inpatient and Outpatient Diabetes Quality Improvements Initiatives in the Division of Endocrinology, she remains actively engaged in initiatives that enhance the quality of care provided to patients with diabetes. Currently she sees patients with difficult to manage diabetes, as well as patients who elect to use evolving technologies such as smart pumps alone or in combination with continuous glucose sensors as a way of achieving and maintaining glycemic control. She served as the American Diabetes Association Chair of the writing group for the Consensus Statement on Inpatient Glycemic Control and was a member of the writing group for the Endocrine Society Clinical Guideline for Management of Hyperglycemia in Hospitalized Patients in Non-critical Care Setting. She has been a contributing member of the American Diabetes Association (ADA) having served as a member Professional Practice Committee where she was involved in the annual review and updating of the Standards of Care for people with diabetes. She also served as a writing group member of the ADA Consensus Report on Diabetes in Older Adults.
Educational Interest
Dr. Korytkowski is actively involved in the education of medical students, residents, endocrine fellows. As a member of the School of Medicine Admissions Committee, she conducts candidate interviews each year. She served as co-director for the first course taken by newly enrolled medical students at the University of Pittsburgh – Introduction to Being a Physician – for five years. During this time, she developed the course syllabus, which continues to be used by current course directors. As part of this course, she introduced a clinical segment on diabetes, which provided medical students with the opportunity to interact with patient volunteers and learn the daily tasks that are required on the part of patients in order to achieve desired metabolic targets. Most recently, she assumed the role of course co-director of the Endocrine Disorders Course for second year medical students. She has mentored medical students and residents for their scholarly projects, many of which have now been published. She is a member of the Fellowship Curriculum Committee in the Division of Endocrinology, which meets on a regular basis to oversee candidate interviews, guide and revise curriculum, and provide feedback to fellows regarding their progress. She has mentored multiple fellows through their research and quality improvement projects, providing guidance in the methodologies for these processes that they can carry into their own careers as clinical or academic endocrinologists. In addition, she is frequently invited to present at Medicine Grand Rounds at the University of Pittsburgh, as well as at other institutions and educational seminars.
