The Columbia University Renal Epidemiology Group is a research group led by Dr. Sumit Mohan at Columbia University Irving Medical Center. The CURE Group focuses on both the epidemiological and clinical trends of kidney transplants, with research spanning many areas ranging from discard rates to center-level performance benchmarks.


Trends in Disparities in Preemptive Kidney Transplantation in the United States

Long wait times for deceased donor kidneys and low rates of preemptive wait-listing have limited preemptive transplantation in the United States. We aimed to assess trends in preemptive deceased donor transplantation with the introduction of the new Kidney Allocation System (KAS) in 2014 and identify whether key disparities in preemptive transplantation have changed.

Major Variation across Local Transplant Centers in Probability of Kidney Transplant for Wait-Listed Patients

Geographic disparities in access to deceased donor kidney transplantation persist in the United States under the Kidney Allocation System (KAS) introduced in 2014, and the effect of transplant center practices on the probability of transplantation for wait-listed patients remains unclear.

Reproducibility of Deceased Donor Kidney Procurement Biopsies

Unfavorable histology on procurement biopsies is the most common reason for deceased donor kidney discard. We sought to assess the reproducibility of procurement biopsy findings.

Association Between Declined Offers of Deceased Donor Kidney Allograft and Outcomes in Kidney Transplant Candidates

In the United States, substantial disparities in access to kidney transplant exist for wait-listed candidates with end-stage renal disease. This study found that transplant candidates appeared to receive a large number of viable deceased donor kidney offers that were refused on their behalf by transplant centers, potentially exacerbating the detrimental consequences of the organ shortage; increased transparency in organ allocation process and decisions may improve patient-centered care and access to kidney transplant.
