Pediatric Nephrology Fellowship Program

Overview and mission

The CHOP Pediatric Nephrology Fellowship Program is a three-year program designed to train pediatricians by providing the necessary clinical and research skills to enable them to pursue an academic career in pediatric nephrology. Our training program accepts 3 fellows per year.

The history, expertise and compassion that make Children’s Hospital of Philadelphia unique are also what makes it the best place for medical trainees.

Specific information by years and/or rotation

Year one

During the first year of training, the fellows will rotate monthly through three services: Inpatient, where they are responsible for the care of nephrology patients admitted to the inpatient service; Consult, where they are responsible for consultations from other services; and Outpatient, where they will spend time in the dialysis unit, transplant clinic, multidisciplinary clinics, and other electives. The fellows are supervised at all times by an attending physician. By the end of the first year, the fellows will be competent in performing percutaneous renal biopsies and prescribing acute dialysis (peritoneal dialysis, hemodialysis, continuous hemofiltration) and chronic dialysis. The fellows will attend outpatient Nephrology continuity clinic once a week. Every patient seen by the fellows is discussed in clinic with an attending physician, and cases are reviewed once a week in our outpatient meeting. The fellows are expected to present cases at appropriate conferences and give lectures to residents and medical students. Night and weekend call is divided evenly between fellows in all years of training.

Year two

The fellows begin research training and may choose a project in clinical, translational, or basic science. Most fellows also pursue didactic training with a Masters or Certificate program at the University of Pennsylvania. Clinical responsibilities will be limited to an outpatient continuity clinic one afternoon per week, peritoneal dialysis clinic once per month, transplant clinic one to two times per month, and on-call responsibilities. Second year fellows will cover the inpatient and/or consult services if the first year fellows are absent.

Year three

The fellows will continue to complete their research projects and didactic training. They will have the same clinical responsibilities, including on-call, as specified in year two. If interested, fellows may supervise residents and junior fellows in a capacity similar to an attending, with continuous support from a staff nephrologist.

Research expectations and opportunities

All fellows are expected to complete a research project in order to sit for the Pediatric Nephrology Subspecialty Board Examination. This usually requires submission of a first-author manuscript related to the research. Many opportunities exist for clinical, translational, or basic science research mentorship with accomplished physician scientists at the Children's Hospital of Philadelphia and the Hospital of the University of Pennsylvania. An NIH training grant to cover the cost of tuition for a Master’s program is available for eligible fellows. All fellows are also expected to participate in a Quality Improvement project.

Tobacco-free hiring policy

To help preserve and improve the health of our patients, their families and our employees, The Children’s Hospital of Philadelphia has a tobacco-free hiring policy. This policy applies to all candidates for employment (other than those with regularly scheduled hours in New Jersey) for all positions, including those covered by the Collective Bargaining Agreement. Job applicants who apply after July 1, 2014 will be expected to sign an attestation stating they’ve been free of nicotine or tobacco products in any form for the prior thirty (30) days. They will also undergo a cotinine test as a part of the Occupational Health pre-placement drug screen administered after the offer of employment has been accepted but before the first day of hire.

Exemptions: Attending physicians (excluding CHOP physicians in the Care Network), psychologists, principal investigators and/or Penn-based faculty are exempt from this process to better align with our colleagues at the University of Pennsylvania Perelman School of Medicine.

Med/peds fellowship

General information

We offer a 4-year combined internal medicine and pediatrics (med/peds) fellowship program with our neighboring institution, the University of Pennsylvania. The med/peds fellow will spend their first year as a clinical adult Nephrology fellow at the University of Pennsylvania, their second year as a clinical pediatric Nephrology fellow at CHOP, and their third and fourth year focused on research with some continued clinical responsibilities in both adult and pediatric Nephrology. All four years will be supervised under both the CHOP and Penn program directors. At the successful conclusion of training, the med/peds fellow will be eligible for board certification with both the American Board of Pediatrics (ABP) and American Board of Internal Medicine (ABIM).

How to apply

Residents interested in applying to our med/peds fellowship program should apply to Penn Nephrology via ERAS at season opening. If selected for an interview, they will meet with both Penn and CHOP program faculty. At the conclusion of interview season, the resident will rank Penn via the National Resident Matching Program (NRMP). If matched with Penn, this also means a match with CHOP, and CHOP will set aside a fellowship slot for the following academic year.
