Title: Predicting Hospital Readmissions Among Kidney Transplant Recipients

Abstract: More than half of kidney transplant recipients are rehospitalized in the year after kidney transplantation, placing a large burden on the hospital system and placing patients at higher risk for poor health outcomes, including infection, graft failure and/or death. Several studies have identified risk factors for hospital admission using traditional statistical methods, but models have been limited by moderate predictive accuracy, the use of static (rather than dynamic) models, and the use of administrative data that may not capture the changing risk factors pre- to post-transplant. The overall goal of this research is to develop and validate rigorous, dynamic risk prediction models, integrate these models within a clinician dashboard to allow for real-time decision making and appropriate interventions for high risk patients. This presentation will discuss the importance of the clinical problem, as well as preliminary data analyses from national surveillance data models and local Emory Transplant Center models. The long term objective of this project is to improve health outcomes of patients and improve the efficiency of clinical care for transplant recipients.

Bio: Dr. Rachel Patzer is an Associate Professor in the Department of Surgery, Division of Transplantation with joint appointment in the Department of Epidemiology, Rollins School of Public Health at Emory University in Atlanta, Georgia. She received her PhD in epidemiology from Emory University in 2011 and her MPH in epidemiology in 2007. Dr. Patzer is the Director of Health Services Research at the Emory Transplant Center, where her primary research focuses on access and outcomes of kidney disease and transplantation. She has additional research interests in healthcare quality, mobile health technology, community based participatory research, predictive analytics, and health services utilization. Dr. Patzer is the principal investigator of the ongoing, NIH-funded Reducing Disparities in Access to Kidney Transplantation (RaDIANT) Study, which is an NIH U01 funded study that aims to conduct a dialysis facility-based randomized, pragmatic trial focused on improving referral for transplantation. She also leads a new R01 grant from the NIH on predictive analytics in transplantation with transplant surgeon Andrew Adams, MD, PhD (Emory) and computer scientist Jimeng Sun (Georgia Tech).  In Dr. Patzer’s previously funded research through the NIH's National Center for Advancing Translational Sciences, she led the team that developed Emory University's first mobile app (iChoose Kidney), which provides an individualized comparison of individualized survival estimates for patients on dialysis vs. living or deceased donor kidney transplantation.
