Background: Peritoneal dialysis (PD) patients have many
risk factors that may affect their clinical outcomes. Age and diabetes status
are unequally distributed in the dialysis population of Singapore. Risk
stratification is a means of reducing the effects of case mix such that
high-risk groups in the dialysis population can be identified. Patients and Methods: Records for 543 patients who started
on chronic dialysis during 2002 - 2005 were retrospectively studied for
survival in the first year on dialysis. The age, sex, ethnicity, and diabetes
status of the patients were noted. Results: For patients 60 years of age and older, we
observed no differences in the prevalences of diabetes, male sex, or Chinese
ethnicity between patients on PD and those on hemodialysis (HD). Patients of
Chinese ethnicity on PD were found to have a higher likelihood of survival in
the first year as compared with patients on HD. Age, sex, and diabetes status
were not associated with survival in the first year. Conclusions: In a single PD treatment center, Chinese
ethnicity conferred a survival advantage in the first year on dialysis. The
reasons for that finding are not clear, but they were not related to age,
diabetes status, or sex.
KEY WORDS: Risk stratification; Chinese; survival; first year.
