Urinary Disorders Q 123

Which criterion is required before a patient can be considered for continuous peritoneal dialysis?
    A. The patient must be hemodynamically stable.
    B. The vascular access must have healed.
    C. The patient must be in a home setting.
    D. Hemodialysis must have failed.

Correct Answer: A. The patient must be hemodynamically stable.

Hemodynamic stability must be established before continuous peritoneal dialysis can be started. Starting dialysis with a PDC is preferable to an HDC in terms of patient morbidity, mortality, and cost. It has also been shown in large observational retrospective studies that there is a survival advantage for PD over HD in the first 1 to 3 years of dialysis.

Option B: Patients selected for PD will undergo PD catheter placement using one of the several techniques described above. Once the catheter has healed, they undergo technique training at a dialysis unit for 2 to 3 weeks, learning the proper aseptic technique to use the catheter for dialysis.
Option C: Peritoneal dialysis is one of the modalities utilized for dialysis. There are several advantages of PD versus HD. Patients using PD will not need to leave home every other day to get dialysis, rather they perform their treatments at home using a very simple principle for removing toxins from their body.
Option D: The 2013 Annual Data Report from the United States Renal Data System also shows a significantly improved adjusted probability of 5-year survival with PD compared to HD. This early survival, for the most part, may be explained by selection bias because healthier patients may be more likely to choose PD as their modality. Patients with comorbid conditions tend to start HD after an acute illness and have high early mortality that is wrongly attributed to their HD modality.
