Paricalcitol-treated patients experience improved hospitalization outcomes compared with calcitriol-treated patients in real-world clinical settings

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
