To the Editor: Dr Rubin and colleagues1 reported that patients receiving peritoneal dialysis
rated their care higher than did patients receiving hemodialysis. We are concerned
that the authors did not account for several factors related to the choice
of peritoneal dialysis vs hemodialysis.
First, patients receiving peritoneal dialysis in this study were more
likely to be white and to have graduated from high school; thus, they were
also more likely to be employed and to have health insurance. This is important
because white patients were more likely to rate their care better, as were
patients with fewer comorbidities.
