Dialysis Facility - National Averages

National averages of common dialysis quality measures, including transfusion, fistula, hospitalization, readmission, mortality, transplant waitlisting…

Part of the CMS Data Feeds Dataset › Dialysis facilities

Dataplex delivers this CMS feed as the analysis-ready table DWV.DIALYSIS_FACILITY_NATIONAL_AVERAGES on Snowflake and Databricks: three snapshot releases spanning 2026–2026, aligned to a single schema, refreshed automatically whenever CMS publishes a new file. Every row carries lineage back to the exact CMS source file that produced it.
