PBJ: Definition and Healthcare Context
Full name: Payroll-Based Journal
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.
