About this program

The Transplant Nephrology Fellowship Training Program at The Ohio State University Wexner Medical Center is a one-year intensive clinical program approved by the American Society of Transplantation. There is one position available each year.

Since this fellowship is not accredited by the Accreditation Council for Graduate Medical Education (ACGME), it is only available to candidates who have completed two years of an ACGME-accredited (or equivalent) nephrology fellowship. 

Candidates completing this training are considered eligible for United Network for Organ Sharing-approved medical directorships for individual transplant programs.

Program highlights

The Transplant Nephrology Fellowship Training Program at Ohio State provides fellows with extensive inpatient and outpatient clinical experience as well as longitudinal didactic teaching. 

The program prepares fellows to:
  • Manage kidney and pancreas transplant recipients at all stages of their care
  • Become competent in immunosuppressive regimens
  • Diagnose and manage complex nephrology issues 

The Transplant Nephrology fellow is expected to perform at the level of a junior faculty member since he or she has completed the traditional nephrology fellowship and is board eligible. Therefore, fellows are allowed a significant amount of input in all decisions regarding immunosuppression as well as patient management.

Our Center

The Comprehensive Transplant Center at Ohio State Wexner Medical Center is one of the largest organ transplant programs in the nation, performing approximately 200 kidney and 30 pancreas transplants annually.

The four full-time transplant nephrologists participate in all aspects of patient management, working alongside the transplant surgeons. Post-transplant care is provided as a multidisciplinary, collaborative model both in inpatient and outpatient settings. The center also provides long-term care for the duration of the allograft function, regardless of longevity.

Transplant Nephrology Fellowship Rotations

The experiences during the 12-month training period tally up to the following breakdown:

  • 7 month (minimum) of inpatient rounds
  • 1 month of tissue-typing lab and working with the organ procurement organization (OPO)
  • 2 months of research – clinical or retrospective chart reviews
  • 1 month of elective
  • 1 month for vacation and to attend national conferences


Inpatient Training

The fellow spends seven months in the inpatient section, gaining experience in the care of early post-transplant patients, immunosuppression management and collaborative management, working alongside the surgeons in a multidisciplinary setting. 

Transplant nephrologists attend two inpatient transplant services:
  • Inpatient transplant medicine service – staffed by an internal medicine resident and intern, as well as a nurse practitioner who assists with patient management and discharges
  • Transplant consult service – provides care for all transplanted patients in the medical center admitted to other services, including the transplant surgery services
Responsibilities include:
  • Daily multidisciplinary bedside rounds on all new post-transplant recipients
  • Daily notes in the electronic medical records (EMR) on all new consults and follow-up patients
  • Performing procedures, including dialysis and transplant renal biopsies
  • Assisting in the education and supervision of house staff

Outpatient Training

The fellow attends one early post-transplant management clinic and one longterm management clinic each week, under supervision.

In this setting, the fellow has the opportunity to evaluate and manage immunosuppression regimens as well as common post-transplant complications such as glucose intolerance, hypertension and opportunistic infection.

Attending the longterm management clinic allows the fellow to understand the concepts of safe immunosuppression reduction to prevent cardiovascular morbidity and manage the various metabolic complications associated with longterm immunosuppression.

Each of the four transplant nephrologists has two half-day clinics every week covering living donor evaluations, pre-transplant kidney and pancreas evaluations and post-transplant follow-ups. The transplant fellow will be assigned to two half-day continuity clinics every week, one to do pre-transplant evaluations and the other to do post-transplant follow-ups.

The fellow will be responsible for the overall care of the patients seen in the clinic for the duration of the training year – vis-à-vis monitoring of the labs, modifying immunosuppression and answering any questions raised the patients.

This format will offer independence in decision making and experience in continuity of care for the patients. Since there are outpatient clinics every day, there will ample opportunities for both the transplant and the general nephrology fellow to work independent of each other.
