Background: The impact of the United States Prospective Payment System (PPS) "bundle payment system" on anemia management within small dialysis organizations (SDOs) was studied to evaluate the financia burden on SDOs.
Methods: Facilities enrolled in the original study on SDOs were grouped into three hemoglobin (Hb) categories by subject-months: > 25% of subjectmonths with Hb < 10 g/dL (sub-10); > 25% of subject-months with Hb > 12 g/dL (super-12); remaining facilities (10 - 12 group). Subjectlevel data aggregated to facility level for Hb concentration, intravenous (IV) epoetin ± (EA) dose per administration, dose titration, and EA administration frequency during the baseline and follow-up periods were described.
Results: Baseline demographic characteristics were imbalanced between the sub-10 (n = 7) and super-12 facilities (n = 5). Mean (SD) Hb concentrations were similar for sub-10 (11.1 (3.0) g/dL) and super-12 (11.6 (2.2) g/dL) facilities during the baseline period, but differed during the follow-up period (10.4 (2.7) vs. 11.4 (2.3) g/dL). The median (Q1, Q3) EA IV dose per administration during follow-up was 3,726 (3,467, 3,961) and 5,712 (4,816, 7,324) units in the sub-10 and super-12 facilities, respectively. A small trend toward upward titration was seen.
Conclusions: Results suggest a difference in anemia management between sub-10 and super-12 facilities during the first year of PPS implementation. Future analyses evaluating patterns of reimbursement and shifts in clinical practice guidelines are warranted globally.
