Medical care is delivered one-patient-at-a-time. But the evidence for practicing is derived by aggregating many patients—typically thousands or tens of thousands of patients—into groups. This group-derived evidence would be highly informative for medical practice if all patients were identical. The dissimilarity of individual patients, however, potentially undermines clinical research as a scientific basis for the practice of medicine.
The Predictive Analytics and Comparative Effectiveness Center (PACE), led by Dr. David Kent, seeks to better understand and address the limitations of using group-derived evidence as the basis for decision making in individual patients. Our approach is based on the close integration of clinical and statistical reasoning. Our goal is to provide clinicians and patients with evidence better tailored to their particular circumstances; we have expertise in clinical medicine, risk modeling, individual patient meta-analysis, and observational comparative effectiveness studies.
The PACE Center seeks to provide clinicians and patients with evidence better tailored to their particular circumstances through risk modeling. Among other projects, Dr. Kent is the Principal Investigator of several federally-funded research grants related to these issues, including several methods grants from the Patient-Centered Outcomes Research Institute (PCORI) and grants from the National Institutes of Health (NIH)/National Institute of Neurological Disorders and Stroke (NINDS) focused on cerebrovascular disease. Dr. Kent works alongside 5 additional faculty investigators and statisticians.

Disseminating Patient-Centered Estimates of Benefit": The goals of this project are to disseminate a clear and clinically-actionable understanding of the variation in patient-centered estimates of benefits of diabetes prevention interventions based on our PCORI-funded prediction model derived directly from the Diabetes Prevention Program (DPP) trial. The Tufts PACE DPP Risk model was developed for use in different electronic health record systems to provide information on a patient's individualized risk for developing diabetes and how well preventive treatment—an intensive lifestyle program or taking Metformin—was likely to reduce risk for the patient.
Publicly Accessible Project Materials
This project aims to conduct a large-scale validation of cardiovascular clinical prediction models (CPMs).
Setting up a PCORI Predictive Analytics Resource Center (PARC) to provide various professional services including development of a portfolio of research activities in the area of predictive analytics.
