Fonteum Care Compare · California

California dialysis facilities: 737 Medicare-certified, 5-star quality data, chain-ownership transparency.

CMS-published 5-star ratings, profit-vs-nonprofit status, chain affiliation, and service offerings (in-center hemodialysis, peritoneal, home hemodialysis training) for every ESRD facility in California.

Editorial note: California has dense local journalism + AARP coverage of ESRD care; Fonteum's contribution is the per-facility chain + 5-star data layer, not editorial commentary.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
