Background

Gaps in knowledge exist regarding anemia management among peritoneal dialysis (PD) patients. We sought to understand international variation in anemia management among patients receiving PD.

Methods

PDOPPS is an international prospective cohort study based on randomly selected national samples of PD patients. Hemoglobin (Hgb), TSAT, and ferritin levels, as well as erythropoiesis stimulating agent (ESA) and iron use collected between 2014-16 were compared in cross-sections of PD patients at study enrolment. Results were analysed by country: Australia and New Zealand (A/NZ), Canada, Japan, United Kingdom (UK), and United States (US).

Results

Mean Hgb ranged from 10.9-11.2 g/dL across countries (table). ESA use was higher in Japan (93%) vs. 65-71% elsewhere, with ESA type varying by country. Median epoetin dose ranged from 2500-7250 units/week. In US and Japan, 87-88% of patients had a TSAT≥20%, compared to 72-76% of patients in other countries. Ferritin >500 ng/mL was most common in US, at 60% compared to 7-35% in other countries. IV iron use was higher in US (53%) than elsewhere (5-18%).

Conclusion

In the largest international study to date of anemia and iron management in PD patients, we have demonstrated comparable Hgb levels across countries but significant variations in markers of iron adequacy and ESA and iron use. Notably, US PD patients have higher ferritin levels, iron saturation and IV iron use than other countries. Future analyses will investigate whether these differences persist after patient- and facility-level adjustments, and will evaluate associations between anemia management practices and clinical and patient-reported outcomes.
