Nephrology nursing is the care of people with kidney disease, from early chronic disease through dialysis and transplantation. Most of it in practice is dialysis, and dialysis nursing is unlike almost any other nursing job in the country.
The reason is the schedule. An in-centre haemodialysis patient comes three times a week, for three to five hours, indefinitely. The nurse sees the same forty people every week for years. There is no discharge, and the relationship ends when the patient receives a transplant or dies.
The modalities
In-centre haemodialysis is the most common. Patients attend a freestanding clinic, are connected through a fistula, graft, or catheter, and are dialysed on a fixed schedule. The nurse's work is assessment before and during treatment, access management, managing intradialytic events — hypotension, cramping, arrhythmia, clotting — and medication given during the session.
Home haemodialysis and peritoneal dialysis shift the treatment to the patient, and the nurse's job shifts to training, troubleshooting, and monitoring. Peritoneal dialysis nursing is largely teaching: sterile technique, catheter care, and recognizing peritonitis early.
Acute and inpatient dialysis covers hospitalized patients, including continuous renal replacement therapy in intensive care, which is a critical care skill as much as a nephrology one. See critical care nursing.
Transplant and pre-transplant care runs alongside all of it. See transplant nursing.
Chronic kidney disease clinics manage patients before dialysis, where the nursing work is slowing progression and preparing people for a decision most of them do not want to make.
Vascular access
Access is the specialty's obsession, because it is the patient's lifeline and its failure is the most common reason for hospitalization in this population. Nurses assess fistulas and grafts at every treatment, cannulate them, watch for stenosis and infection, and manage catheters as a last resort. A nurse who cannulates badly damages an access the patient may need for a decade. See infusion and vascular access nursing.
Certification
The Nephrology Nursing Certification Commission certifies across the whole dialysis team, which reflects how the units are actually staffed:
- CNN — registered nurses, requiring at least 3,000 hours across multiple nephrology practice areas.
- CDN — registered nurses in dialysis, requiring at least 2,000 hours caring for dialysis patients.
- CD-LPN and CD-LVN — licensed practical and vocational nurses, with the same 2,000-hour requirement.
- CNN-NP — nurse practitioners, requiring at least 2,000 hours in nephrology.
- CCHT and CCHT-A — clinical hemodialysis technicians, at entry and advanced levels.
The technician credentials matter more here than the equivalent would elsewhere. Dialysis units run on technicians who perform much of the treatment under nursing supervision, and the registered nurse's role is assessment, judgment, and oversight rather than hands-on delivery of every session. That makes delegation and supervision a daily practical skill in this specialty. See scope of practice.
The setting
Most dialysis in the United States is delivered by two large national chains in freestanding clinics rather than by hospitals, which shapes the job. Hours are early and long — units typically run several shifts starting before dawn — but they are predictable, and there are no nights and few weekends outside acute settings.
Chronic kidney failure is closely tied to diabetes and hypertension, and the patient population is disproportionately older, poorer, and non-white. Nurses in this specialty spend a great deal of time on transport, insurance, medication cost, and food access, because those are the things that determine whether the patient makes their treatments. See diabetes nursing and public health nursing.
