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. Conclusion: About half of peritoneal dialysis patients with inadequate dialysis did not have a prescription change and could benefit from modifications in their dialysis prescription.
