Incremental PD may preserve kidney function better than full dose dialysis3

Start with Incremental PD and preserve the choice of PD

When the modality choice is PD, choose Incremental PD

  • Incremental PD, where less than standard ‘full-dose’ PD is prescribed in people initiating PD and done with the intention of increasing the prescription if and when residual kidney clearance declines, may ease the transition to dialysis for patients with chronic kidney disease – fewer exchanges, more time to do the things that matter to them1
  • Starting patients on Incremental PD allows a person-centered approach by significantly reducing the workload of dialysis for those doing PD, reduces exposure of the peritoneal membrane to glucose, and may lessen mechanical symptoms2
  • The dialysis dose is gradually increased to compensate for renal function decline and to meet adequacy targets3

Incremental PD offers clinical, economic and lifestyle benefits

Incremental PD icon

Incremental PD strategies achieve outcomes that are at least as good as full dose PD prescriptions in patients with RKF1

Protection icon

Protection of patient modality goal6

• PD option often lost at low GFR if insufficient time for catheter and training

• Urgent start PD often not available

Benefits icon

Benefits may include7,8 

• Improvement of uremic symptoms

• Reduces burden on patient

• Allows more time for the patient to adjust to dialysis therapy

• Minimized glucose exposure

Incremental PD may preserve kidney function better than full-dose PD without increasing risk of Peritonitis3

chart showing Inversed probability weighted, adjusted anuria-free survival for incremental PD and full-dose PD

Overall median time to the first peritonitis was 2.3 years for patients on Incremental PD and full dose3,*

80% of patients survive anuria-free 2+ years longer with incremental PD3

Study Design

A single center, retrospective cohort study of incident patients (n=347 patients between January 2007 through December 2015) was conducted to compare incremental PD with full-dose PD with the following specifications3

Incremental PD Arm Full Dose PD Arm
1-2 dwells per day on CAPD, 7 days a week The initiation of PD with 3 or more exchanges per day for CAPD, 7 days a week
A peritoneal Kt/V < 1.7 per week, but a total Kt/V ≥ 1.7 per week Irrespective of residual renal function (RRF)
Baseline GR 6.9 ± 3.00 Baseline GFR: 6.5 ± 2.43
  • No significant difference in sex, the composition of primary renal disease comorbidities, and the use of ACEI or ARB between the two groups
  • Exclusion criteria: Total duration of PD less than 6 months, initiation of PD at another hospital, urine volume of < 200 mL per day at the time of initiating PD, previous hemodialysis, less than 16 years of age

First Episode
Incremental PD (n=176) Full-dose PD (n=171)
Number of first peritonitis 71 73
Follow-up time (patient-year) 692.9 750.0
Peritonitis incidence (episode / patient-year)  (95% CI) 0.10 (0.08-0.13) 0.10 (0.08-0.12)

* Study design: A retrospective, randomized study (n=347 patients) between 2007-2015, comparing patients on incremental PD and full dose PD. Primary outcome in the study was anuria-free survival comparing IPD and full dose PD. Inversed probability weighted, adjusted anuria-free survival using time-dependent Cox proportional  hazards model.  This was an observational, single-center study, which included only CAPD patients with >200mL daily urine volume.
† Study design: A 10-year single center study (n=100) between 2002-2012 comparing incident patients on incremental PD and standard PD.
