What is the Payroll Based Journal (PBJ)?

The Payroll Based Journal (PBJ) is the CMS system through which nursing homes and long-term care facilities electronically submit quarterly direct-care staffing data — actual hours worked by day, job type, and employee-versus-contract status. CMS uses PBJ data to calculate the Staffing Rating in nursing home star ratings, and publishes it as a public-use file.

Full name: Payroll-Based Journal

Short explanation

The Payroll-Based Journal (PBJ) is a CMS system requiring nursing homes and long-term care facilities to submit direct care staffing data electronically on a quarterly basis. Mandated under the Affordable Care Act and the SNF Staffing Final Rule, PBJ data includes actual hours worked by nursing staff by day, job type, and hire type (employee vs. contract staff). CMS uses PBJ data to calculate the Staffing Rating component of nursing home star ratings on Care Compare. PBJ data is publicly available and widely used in nursing home staffing research.

How it’s used

  • CMS Payroll-Based Journal (PBJ): Fonteum uses PBJ data to populate the staffing domain of nursing home research studies and to contextualize star-rating staffing components.
  • CMS Care Compare (nursing homes): the Staffing domain of the nursing home five-star rating is calculated entirely from PBJ-submitted payroll data.

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.
