Mission and Goals

The Division of Nephrology and its fellowship training program are dedicated to excellence in patient care, medical education, basic and clinical research, and service to the community.

Nephrology Fellowship Training

The UC Davis Nephrology fellowship program is an ACGME-accredited 2 year clinical program that provides the full breadth of nephrology training. We accept 3 fellows each year. Our program highlights include an extensive home dialysis (peritoneal and home hemodialysis) program and an ASDIN-accredited Interventional Nephrology program. A third year for research is also available for fellows who have an ongoing research project.

Salary and Benefits

The annual salary for PGY 4 and PGY 5 fellows, based on academic year 2020-2021, is $68,426.11 and 71,226.23, respectively. Active clinical fellows are eligible for coverage in the University of California medical, dental, vision, life and disability insurance plans. You can also cover your spouse or domestic partner and dependent children up to age 26 in medical, dental and vision coverage. The University of California pays the entire cost of coverage for you and your enrolled dependents. For more information, please visit the UC Davis Graduate Medical Education website.

Living In Sacramento

Sacramento and its surrounding region have so much to offer, including restaurants that pride themselves on farm-to-fork cuisine to a variety of outdoor recreation spots to family-friendly events. Here’s a glimpse of what you and your family can expect should you decide to call Northern California your home.

UC Davis Medical Center

Most of the fellowship training is on the University of California Davis medical campus in Sacramento. This includes the inpatient consultation service and transplant nephrology rotations. A new, state-of-the-art 12 bay dialysis unit located in the heart of the hospital allows dialysis care for ward patients requiring renal replacement therapy. Fellows have a dedicated workspace that allows for appropriate physical distancing and extensive resources including their own centrifuge and microscope for urine analyses and a nephrology point of care ultrasound.

Additional rotations on the University medical campus include interventional nephrology, transplant nephrology and apheresis.

The fellows have continuity renal clinic in the adjacent ambulatory care clinic.

Veterans Affairs Medical Center

The VA Mather Field Medical Center is located 11 miles east of the University hospital. Fellows have multiple weeks per year at the VA with both inpatient and ambulatory experience. Renal clinic at the VA is also part of the ambulatory experience.

Community Dialysis Clinics

Our fellowship emphasizes home dialysis. Much of the exposure to peritoneal dialysis and home hemodialysis takes place in the home training programs run by various dialysis providers. UC Davis nephrologists are medical directors for several of these dialysis clinics. Fellows will additionally participate in hemodialysis rounds and sit in on administrative meetings to understand the role of the medical director in running a dialysis clinic.

Two Nephrology Fellowship sites.

Nephrology Fellowship Rotations Examples

Each rotation in our fellowship program is 2 weeks in duration. We have found that 2 weeks provides the best balance between continuity, workload, education and diversity over the year.

    • UC Inpatient Consultation Service: 2 fellows are assigned, each working one-on-one with a faculty attending. Residents and medical students are usually part of the team. Fellows alternate admission days and pick up patients from our night float system. Fellows do not take night weekday call on the University inpatient consultation rotation. Weekends are split amongst all fellows in the program. The total teaching service census ranges from 25-40 patients, with overflow picked up by faculty on service. Clinical exposure will include all modalities of kidney replacement therapy (HD, SLED, CRRT, PUF and PD), and a wide breadth of acute and chronic pathology within a diverse patient population.
    • VA Inpatient Consultation and Outpatient Service: There is 1 fellow at the VA for working with the VA faculty nephrologists. The census averages 8-12 patients. The fellows do not take weekend or night calls for the VA. During this block, fellows will participate in the VA renal clinics on Monday and Tuesday afternoons. Fellows also have 1 half-day of UC continuity clinic each week.
    • Transplant Nephrology: There is 1 fellow on transplant who works alongside the transplant nephrology fellow and transplant faculty. Fellows will have 2 half-days of transplant clinic weekly, along with their 1 half-day of UC continuity clinic. Fellows do not take weekend or night calls for transplant.
    • Interventional Nephrology: Fellows work with our interventional nephrologists at the University hospital, placing catheters (both temporary and tunneled) as well as participating in angiogram and angioplasty procedures related to hemodialysis vascular accesses. Fellows also have 1 half-day of UC continuity clinic each week.
    • Night Float: A fellow is on weeknight University calls from home Monday-Thursday, except for holiday weekdays, between 5 pm and 6 am the following morning. Fellows have a half-day UC continuity clinic and a half-day telehealth clinic during the week.
    • Outpatient Dialysis: A fellow on outpatient dialysis is supervised by a core group of faculty at community in-center HD clinics as well as home dialysis clinics (PD and home HD). The focus is on management of new start as well as stable dialysis patients in a multidisciplinary setting. There are some dedicated half-days for covering a structured dialysis curriculum, wellness, and other scholarly activities during this time. Fellows also have 1 half-day of UC continuity clinic each week.
    • Research: In the second year, fellows have dedicated research time to work with our research faculty, on their own projects, or on other scholarly activities. Fellows have 1-2 half-day continuity clinics during their research block.
    • Apheresis: Apheresis experience is courtesy of the Department of Pathology, which runs this service at UC Davis. Prior fellows have requested this experience as many have joined practices where nephrologists oversee apheresis.

A sample schedule for the year is shown below. Fellows only cover UC inpatient consult on weekends. Fellows do not cover the VA inpatient service or the UC transplant service on weekends. Schedules may vary slightly from fellow to fellow depending on requested experience.

Journal club and nephrology grand rounds are held every Tuesday morning from 7:30 to 9:30, starting in August. Fellows are expected to present at both conferences each year.

Fellows also attend a Friday afternoon conference. The topics cover the broad range of nephrology, rotating through the topic list every 2 years. Some afternoons are dedicated to Board review and others for fellows to present interesting or educational cases.

UC Davis nephrology has sponsored regional CME events over the last couple of years. We have had great engagement. Importantly, graduates of the fellowship program have returned for these events – it is always a joy to see our alumni!

The Division sponsors our second year fellows to attend the American Society of Nephrology Kidney Week, including the pre-conference courses. This year, we are planning a new activity in late winter for our first year fellows to have an immersive academic week to review high yield nephrology topics and landmark studies.

The education and training of future physicians and specialists are the key missions of the University of California system. Our fellows truly represent our legacy. At UC Davis, fellows are supportive of one another. Our faculty and staff are involved in their well-being.

The wellness of our fellows is important and we continue to evaluate schedules and service commitments to maintain trainee wellness. Wellness days can be found on Interventional Nephrology, Outpatient Dialysis, and Research rotations where you can take personal time, any way they see fit, without duty requirements.

The fellowship coordinator has organized fellow dinners, outings and other holiday activities. In the present era of COVID-19, these have looked different but remain an integral part of our program. UC Davis Graduate Medical Education has additional information on trainee wellness.

UC Davis is a major research university. Research in the UC Davis Division of Nephrology include works on molecular mechanisms and clinical outcomes in diabetic nephropathy, mechanisms of renal fibrosis and injury, mitochondrial dysfunction in chronic kidney disease and inflammation,  clinical outcomes in ESKD patients, and molecular mechanisms of renal cell cancer.

Fellows also present their projects and case reports at the annual ASN conference. Our fellows also participate in book chapters and invited review articles.
