The following sample procedures are designed to assist the nurse caring for the PD patient to perform standardized clinical procedures. These procedures are intended as guidelines only and are based on best practices from premier PD programs and the current literature.
Frequency of monitoring
PET/PFT
It is generally recommended to perform baseline peritoneal function testing (PET or PFT) approximately one month after initiation of PD. Waiting several weeks before performing the PET/PFT reduces the variations observed in peritoneal transport rates often seen immediately after initiation of PD. The baseline test could be performed earlier if it is the only convenient time or when dictated by medical circumstances (for example, inadequate ultrafiltration). The test should be repeated whenever changes in peritoneal transport are suspected or conversely, on an annual basis if possible.
Delivered Dialysis Dose
Many clinicians have recommended measurement of total solute clearance (delivered PD dose plus RRF) every 3 to 4 months. Peritoneal and renal contributions in patients with RRF (urine volume > 300 or glomerular filtration rate (GFR) > 1 ml/min) are considered. Testing should include a 24 hour urine collection and a 24 hour effluent batch test for urea and creatinine clearance. The 24 hour urine collection is not necessary in patients without residual renal function.
