title: Oral pulsed calcitriol protocol reduces the prevalence of hyperparathyroidism in a PD unit.
abstract: A quality assessment (QA) activity revealed that the percentage of parathyroid hormone (PTH) levels above 300 micrograms/dL was higher in the peritoneal dialysis (PD) unit than in the hemodialysis (HD) unit (44% vs 27%). To reduce the proportion of patients with a target PTH above 200 micrograms/dL, a protocol that emphasized control of the serum phosphate level, standard pulsed doses of calcitriol, and increased patient education was created for the management of renal osteodystrophy. Serum calcium, phosphate, and PTH levels were obtained according to the protocol from July 1994 through June 1996. The percentage of patients achieving a PTH level below 200 micrograms/dL increased from 40% in June 1994 to 57% in June 1996. Significant differences were found in PTH levels at baseline and at test times 1, 2, and 3. Hypercalcemia (Ca > 12) occurred in 4% of the 532 Ca levels drawn during the study period and were due to breaches of protocol. In conclusion, we have confirmed previous work indicating that pulsed calcitriol can control elevated PTH levels in PD patients. Furthermore, we have developed a protocol that can be used as a QA tool to reduce the prevalence of hyperparathyroidism in the outpatient PD setting without inducing excess hypercalcemia.
