Hemodialysis (HD) and peritoneal dialysis (PD) are associated with similar mortality rates among patients initiating dialysis who are eligible for both modalities, according to a new study.

The study, led by Bed Wong, MD, of the University of Calgary in Alberta, Canada, looked at 1579 HD and 453 PD patients in Ontario, Canada, who had received at least 1 outpatient dialysis treatment and had completed a multidisciplinary modality assessment. Although PD was associated with a lower risk of death among patients younger than 65 years, the modalities were associated with similar survival regardless of age after the investigators excluded about one-third of incident patients deemed ineligible for PD, according to a paper published online ahead of print in the American Journal of Kidney Diseases. In addition, the effect of modality on survival did not vary over time.

“Future comparisons of dialysis modality should be restricted to individuals who are deemed eligible for both modalities to reflect the outcomes of patients who have the opportunity to choose between HD and PD in clinical practice,” the authors concluded.
