Nephrology Fellowship at NYC Health + Hospitals/Elmhurst

The Nephrology Fellowship at NYC Health + Hospitals/Elmhurst combines the intellectual rigor of nephrology with the compassion required to care for patients facing kidney disease. Established in 2006 and accredited by the Accreditation Council for Graduate Medical Education (ACGME), our two-year program trains two fellows annually, preparing them for subspecialty certification by the American Board of Internal Medicine.

Training occurs across three institutions—The Mount Sinai Hospital, Elmhurst Hospital Center, and Queens Hospital Center—where fellows develop expertise that extends well beyond technical proficiency. Our diverse patient population ensures they gain broad clinical exposure, managing everything from acute kidney injury and complex electrolyte disorders to chronic kidney disease, hemodialysis, peritoneal dialysis, and transplant medicine.

Fellows gain further hands-on experience with rare and challenging cases through our high-volume consultative service. With both inpatient and outpatient dialysis units on-site, a dedicated transplant rotation at Mount Sinai's Recanati/Miller Transplantation Institute, and the option to pursue a third year in Critical Care Medicine, our program builds the foundation and confidence needed to practice nephrology anywhere.

Our curriculum is structured around rotations at Elmhurst Hospital Center, Queens Hospital Center, and The Mount Sinai Hospital, which together provide comprehensive training in chronic kidney disease (CKD), acute kidney injury (AKI), end-stage renal disease, and transplant medicine.

Most clinical training takes place at Elmhurst Hospital Center, where fellows rotate through outpatient CKD and transplant clinics, manage both hemodialysis and peritoneal dialysis patients, and serve on the acute consult service addressing AKI and electrolyte disorders. At The Mount Sinai Hospital, fellows gain both inpatient and outpatient transplant experience at The Recanati/Miller Transplantation Institute at Mount Sinai. To further broaden their expertise, fellows engage in the consult service at Queens Hospital Center.

Fellows interested in critical care have the option to pursue a third-year track in Critical Care Medicine. In this track, they can spend either their first- or third-year training primarily within The Mount Sinai Hospital's intensive care units, with additional rotations at Mount Sinai Queens, James J. Peters Department of Veterans Affairs Medical Center, and Elmhurst Hospital Center.

Our program is organized into two-week blocks that provide exposure to all aspects of nephrology. At the heart of the fellowship is our busy renal consultative service, where fellows gain experience in challenging cases from patients from around the world. With at least one-third of consults originating from Elmhurst Hospital Center's three intensive care units, fellows learn to provide and manage renal replacement therapy. They gain experience in managing acute and chronic inpatient renal diseases, including fluid and electrolyte disorders, acid-base disorders, and glomerular diseases.

Our clinical experience extends across multiple settings. At Elmhurst Hospital Center's dialysis center, fellows master the complex outpatient management of hemodialysis and peritoneal dialysis patients. They also participate in a one-month rotation at the Recanati/Miller Transplantation Institute at Mount Sinai, joining a team of surgeons and nephrologists who perform 150 renal transplants annually.

Our weekly clinics are designed to provide continuity of care: one afternoon each week is dedicated to managing chronic kidney disease patients with a focus on hypertension and diabetes, while one morning a week is reserved for a renal/immunology clinic, where fellows care for glomerulonephritis and outpatient transplant patients. Additional training opportunities include a renal pathology elective at The Mount Sinai Hospital, where fellows review native and transplant renal biopsies with expert renal pathologists. Fellows also have time to design electives based on their chosen track, along with one month of vacation time and protected time for educational conferences.

Fellows additionally participate in a robust conference schedule that reinforces clinical learning and fosters scholarly discussion. Our weekly conferences include the Clinical Conference, Journal Club, Medicine Grand Rounds, and daily Medicine Noon Conferences. Fellows also attend a monthly Renal Pathology Conference, twice-weekly Nephrology Core Curriculum sessions, and the Transplant Core Curriculum conference.

Our range of clinical experiences allow each fellow numerous opportunities to identify a particularly interesting clinical question to pursue through dedicated research time. Our scholarly activities allow them the chance to analyze quality improvement initiatives and to incorporate this knowledge into practice. Current areas of research focus include: 

  • An outcomes study of the use of sustained low efficiency daily dialysis in the ICU setting 
  • The presentation of various ethnic groups to end-stage renal disease 
  • Hyponatremia and its treatment
  • Other quality improvement initiatives to help deliver the best care to our patients

To further deepen their understanding of the role of research in nephrology care, fellows have the opportunity to attend national conferences, including the annual renal pathology conference at Columbia University Irving Medical Center, and the annual ultrasound course at Emory University.

Our program participates in the National Resident Matching Program (ACGME Institution Code: 359503), and we accept applications through the Electronic Residency Application Service. For selected candidates, interviews occur during the fall, and the match is generally announced in December.

Complete applications include:

  • United States Medical Licensing Examination Scores
  • Three letters of recommendation
  • Academic transcripts 
  • Personal Statement
  • Curriculum Vitae
  • Photo

We ask that those who are interested in the third-year Critical Care track contact Ernesto Dorch, our Coordinating Manager.
