A Canadian study of 4,247 patients on peritoneal dialysis (PD) found that older age, black race, switching to PD from hemodialysis (HD), and diabetes in women were associated with a significantly increased risk of peritonitis. In contrast to previous studies, continuous ambulatory PD and automated PD were similar with respect to peritonitis risk.

Study findings appear in the Clinical Journal of the American Society of Nephrology (2009; published online ahead of print).
