Five Star Technical Users' Guides
⭐ Dive into the detailed measures & methods used to calculate nursing homes’ Five Star ratings
How to Use the Five Star Technical Users' Guide
The Technical Users’ Guide describes the methods and measures to compute an Overall Five Star rating as well as three sub-components of the overall rating:
- Health Inspections – Based on weighted outcomes from state health inspections findings of the number, scope, and severity of deficiencies from the three most recent annual onsite surveys, plus findings from complaint investigations and infection control surveys in the prior 36 months
- Staffing – Based on six staffing levels and turnover measures. Nurse staffing levels are measured in hours per resident per day and derived from quarterly Payroll-Based Journal reports and MDS derived resident census. Staffing level measures are case-mix adjusted. Turnover measures use six consecutive quarters of PBJ data for nursing staff and administrators.
- Quality Measures – Based on facility performance on nine long-stay and six short-stay measures reported on the MDS and claims for resident care.
Since 2008, the Centers for Medicare & Medicaid Services (CMS) has displayed Five Star ratings on its Nursing Home Compare public reporting site. Every nursing home participating in Medicare or Medicaid receive star ratings so that residents and families may easily assess and understand nursing home quality.

- Case-mix adjusted total weekend nurse levels: HPRD
- Total nurse turnover: % last 12 months
- RN turnover: % last 12 months
- Administrator turnover: # who left in last 12 months
In addition, CMS changed the bonus, such that only 5 star staffing levels earns a 1 star increase in the overall five star rating. Before both 4 and 5 star staffing levels earned the increase.
