Robert A. Gabbay, MD, PhD, has 20 years of clinical and research experience and is Chief Medical Officer and Senior Vice President at Joslin Diabetes Center. His research focuses on improving primary care health care delivery to enhance diabetes outcomes and patients’ experiences.

Dr. Gabbay served as faculty chair of Pennsylvania’s statewide Chronic Care Model-focused Patient Centered Medical Home (PCMH) initiative (Chronic Care Initiative) involving more than 150 primary care practices with support from 17 payers. He has also worked as Principal Investigator on two AHRQ-funded PCMH projects before coming to the Joslin. The first, studied the experience of 25 practices in the first regional rollout of the Pennsylvania initiative in Southeast Pennsylvania. Under the R18, Dr. Gabbay is using a mixed methods approach to evaluate the clinical and proximal outcomes of the PCMH intervention, the effects of the intervention on resource utilization and costs, and patient and provider satisfaction and experience with the PCMH intervention. In the second study, Dr. Gabbay was selected by AHRQ to help develop state-level infrastructure for primary care transformation under AHRQ’s Infrastructure for Maintaining Primary Care Transformation (IMPaCT) program. Pennsylvania was one of four states selected for this initiative aimed at laying the foundation for a nationwide primary care extension service.

Dr. Gabbay has also worked with the Pennsylvania Chapter of the American Academy of Family Physicians (PAFP) both on a collaborative and an investigation level. Dr. Gabbay served as Principal Investigator on the PAFP Residency Program Collaborative Evaluation which evaluated the clinical and proximal outcomes of a PCMH intervention at 26 family medicine residency practices across Pennsylvania. He has also served in a collaborative role, working alongside the PAFP during the statewide Chronic Care Initiative.

Dr. Gabbay’s focus at Joslin Diabetes Center is to foster innovation within the walls of Joslin as well as disseminating these approaches regionally, nationally, and internationally. He is dedicated to creating a model for the patient-centered medical neighborhood for diabetes, a compliment to his patient centered medical home research. The medical neighborhood will ensure patient centered coordinated care between the team of health professionals that are required to meet the patient’s needs. He is also committed to providing the best quality possible to our diabetes patients while exceeding the highest national clinical quality measures.
