- Renal replacement therapy options: Patients with end-stage renal disease (ESRD) have three main treatment modalities: hemodialysis, peritoneal dialysis, and kidney transplantation. Each option carries distinct benefits and limitations that must be weighed against individual patient factors, preferences, and medical suitability.
- Hemodialysis overview: In-center hemodialysis requires patients to visit a dialysis center three times weekly for several hours. It filters blood through an artificial kidney machine, requiring vascular access creation and maintenance. It offers structured medical supervision but imposes travel and scheduling constraints.
- Peritoneal dialysis overview: PD uses the patient's peritoneal membrane as a natural filter. Dialysis fluid is instilled into the abdominal cavity via a catheter, where waste products diffuse across the membrane. Exchanges can be performed manually (CAPD) or via an automated cycler (APD) during sleep.
- Transplantation considerations: Kidney transplantation provides the best long-term outcomes for eligible patients, freeing them from dialysis. However, organ availability is limited, and patients must meet criteria including absence of active infection, adequate cardiovascular health, and psychosocial readiness.
- Home PD advantages: Home PD allows patients to perform dialysis at home or work, offering greater independence and flexibility. It reduces travel burden, allows more frequent exchanges for improved clearance, and is associated with better preservation of residual kidney function compared to hemodialysis.
- Patient-centered decision making: Choosing a modality should involve shared decision making between the patient, family, and healthcare team. Factors include lifestyle, distance to center, ability to self-care, home support, and comorbid conditions. Education on each option is critical early in the disease course.
- Global PD utilization trends: PD utilization varies widely by country. In some regions, PD accounts for a significant portion of dialysis due to cost-effectiveness and infrastructure advantages. In the United States, PD use is growing, driven by policy changes like the Advancing American Kidney Health initiative.
- Role of healthcare team: A multidisciplinary team including nephrologists, PD nurses, dietitians, social workers, and pharmacists collaborates to support home PD patients. Each member contributes unique expertise to optimize patient outcomes and address barriers to successful home therapy.
- PD catheter types and placement: The PD catheter, typically a Tenckhoff catheter, is surgically placed into the peritoneal cavity. Catheters may have straight or coiled intraperitoneal segments and single or double cuffs. Proper placement and exit site orientation are critical to reduce complications like leakage, obstruction, or infection.
- Infection prevention strategies: Peritonitis and exit site infections are major risks in PD. Strict aseptic technique during exchanges, daily exit site inspection and cleansing, and proper hand hygiene are essential. Prophylactic antibiotics prior to catheter insertion and during certain procedures further reduce infection rates.
- Dietary and fluid management: While PD allows more liberal dietary intake than hemodialysis, patients must still monitor sodium, potassium, and phosphorus levels. Fluid restrictions may be less strict due to continuous ultrafiltration, but careful tracking of daily weight and blood pressure is necessary to avoid fluid overload.
Scope of Practice
Role: PD Nurse in Home Dialysis Program
Within scope:
- Educating patients and caregivers on PD principles and exchange techniques
- Assessing patient suitability for home PD and conducting home visits
- Coordinating catheter placement and postoperative care with surgical team
- Adjusting PD prescriptions under nephrologist guidance
- Monitoring patient outcomes, managing complications, and providing ongoing support
Outside scope:
- Performing catheter insertion or surgical procedures
- Prescribing medications independently without physician order
- Diagnosing medical conditions or interpreting lab results without supervision
- Operating as a primary care provider for non-dialysis issues
- Modifying dialysis prescription without nephrologist approval
Quick Revision
- Renal replacement therapy includes hemodialysis, peritoneal dialysis, and transplantation, each with unique indications and patient considerations.
- Home PD offers flexibility, independence, and preservation of residual kidney function.
- The PD nurse plays a central role in patient education, assessment, and ongoing management within a defined scope of practice.
- Multidisciplinary collaboration ensures comprehensive care for home PD patients.
