Primary reason for hospital admission, by initial outpatient dialysis treatment modality. Hospitalizations were classified based on the primary reason for admission: related to dialysis therapy, complications of kidney disease unrelated to dialysis therapy, or unrelated to kidney disease or dialysis therapy. In patients treated with peritoneal dialysis (PD) and hemodialysis (HD), most hospitalizations were unrelated to kidney disease or dialysis therapy. We observed no significant differences by modality in the proportion of admissions that fell into each category.
