title: Response to inadequate dialysis in chronic peritoneal dialysis patients. Results from the 2000 Centers for Medicare and Medicaid (CMS) ESRD Peritoneal Dialysis Clinical Performance Measures (PD-CPM) Project.
abstract: BACKGROUND
  It is not known if patient prescriptions are being changed if patients are receiving an inadequate dose of peritoneal dialysis.
  
  
  METHODS
  Data from the 2000 Centers for Medicare and Medicaid were used to obtain data on dialysis adequacy and dialysis prescriptions.
  
  
  RESULTS
  A total of 359 of 1,268 (28%) adult peritoneal dialysis patients had a total weekly Kt/V urea (twKt/V) less than 2.0 and 436 of 1,245 (35%) patients had a total weekly creatinine clearance (twCrCl) less than 60 L/wk/1.73 m2, defined as "inadequate dialysis." Among chronic ambulatory peritoneal dialysis (CAPD) patients, 81 of 188 (43%) patients had inadequate dialysis and a change in the peritoneal dialysis prescription within 6 months of the initial adequacy value. Among cycler patients, 106 of 197 (54%) patients had inadequate dialysis and a change in the prescription. Thirty-six of 46 (78%) CAPD patients and 48 of 56 (86%) cycler patients had an improvement in twKt/V after the prescription was revised. Thirty-two of 42 (76%) CAPD patients and 45 of 57 (79%) cycler patients had an improvement in twCrCl after the prescription was changed. For these patients, twKt/V increased from 1.6 +/- 0.3 to 2.1 +/- 0.5, with an increase in the peritoneal Kt/V urea from 1.5 +/- 0.3 to 1.9 +/- 0.4. Similarly, twCrCl increased from 46.3 +/- 7.5 to 59.1 +/- 10.6 L/wk/1.73 m2 with an increase in the peritoneal CrCl dose from 42.0 +/- 9.1 to 52.7 +/- 9.9 L/wk/1.73 m2.
  
  
  CONCLUSIONS
  About half of peritoneal dialysis patients with inadequate dialysis did not have a prescription change and could benefit from modifications in their dialysis prescription.
