Abstract

BACKGROUND:

Abnormalities of serum calcium, phosphorous and intact parathyroid hormone (PTH) are associated with morbidity and mortality in haemodialysis patients. Pharmacologic parenteral vitamin D administration is used to correct these abnormalities; however, the relationship between vitamin D therapies and hospitalizations has never been addressed.

METHODS:

Healthcare data from January 1999 to November 2001 were analysed for 11,443 adult haemodialysis patients who received at least 10 doses of vitamin D therapy. Multivariate models were used to evaluate the effects of vitamin D therapy on: (i) total number of hospitalizations, (ii) total number of hospital days and (iii) risk of first hospitalization after initiation of vitamin D therapy.

RESULTS:

When compared with the calcitriol group, the paricalcitol group had a lower risk of first all-cause hospitalization (14% less likely, P<0.0001), fewer hospitalizations per year (0.642 fewer, P<0.001) and fewer hospital days per year (6.84 fewer, P<0.001). In the paricalcitol and calcitriol groups, respectively, 5.6 and 41.3% patients switched to another vitamin D compound. For those patients who started and remained on the same vitamin D product, paricalcitol-treated patients experienced 0.846 fewer hospitalizations per year and 9.17 fewer hospital days per year, P<0.001 for both. The paricalcitol group also had a lower risk of first PTH-related hospitalizations, fewer PTH-related annual hospitalizations and fewer days per year.

CONCLUSION:

Paricalcitol-treated patients experienced fewer hospitalizations and hospital days per year when compared with calcitriol-treated patients. Initiating vitamin D therapy with paricalcitol may result in overall savings of approximately 7600-11,000 US dollars per patient per year. A randomized, controlled, blinded study would be valuable in confirming and understanding these results.
