Objectives of this study were: to measure hemodialysis patients' knowl
edge about erythropoietin and iron therapy; to design written educatio
nal material to address any perceived deficiencies; and to assess the
impact of the educational material on patients' knowledge and understa
nding. The study design was to interview, provide written material and
re-interview. This study showed that hemodialysis patients were defic
ient in their knowledge about erythropoietin and iron therapy. The ris
k of deficiency was higher if patients were older than 60 years or if
they had not completed high school. Written educational materials help
ed rectify this deficit. We recommend that patients receive written in
formation to reinforce verbal instruction regarding their medications
and that counseling be especially aimed at high-risk populations. We a
lso recommend that written material be aimed at a reading level below
eighth grade.
