Star ratings
CMS rates every certified nursing home from 1 to 5 stars in three areas and combines them into an overall rating. The ratings compare homes with each other: 5 is much above average, 3 is average, 1 is much below average.
Overall rating
Much above averageThe headline score, from 1 to 5 stars.
✓ Better than the state average. State 3.2 · National 3.0
How is this scored?
Three steps: start with the health inspection stars; add one star if staffing is 5 stars (subtract one if it is 1 star); then add one star if quality measures are 5 stars (subtract one if 1 star). It never goes above 5 or below 1, and a home with 1 health inspection star can gain at most one star from the other two. It compares homes with each other; it is not a pass/fail grade. [11]
Health inspections
Much above averageHow the home did in recent state inspections and complaint investigations.
✓ Better than the state average. State 2.8 · National 2.8
How is this scored?
Based on the two most recent annual inspections plus 36 months of complaint and infection-control inspections, and on how many revisits were needed to confirm fixes. Each citation is weighted by scope and severity. Homes are then ranked within their own state: the best 10% (lowest scores) earn 5 stars, the middle 70% earn 2, 3 or 4 stars in equal shares, and the worst 20% earn 1 star. [11]
Staffing
AverageHow many nurses care for each resident, and how stable the nursing team is.
✗ Worse than the state average. State 3.3 · National 3.0
How is this scored?
Six measures: three of staffing level (total nurse, registered nurse and weekend nurse hours per resident per day, adjusted for how much care residents need) and three of turnover (nursing staff, RNs and administrators). The hours come from payroll records submitted to CMS each quarter; turnover uses six quarters of that data. [11]
Quality measures
Much above averageHow residents are actually doing.
✓ Better than the state average. State 4.2 · National 3.7
How is this scored?
Scores 15 quality measures drawn from resident assessments (the Minimum Data Set) and Medicare claims, such as falls with major injury, pressure ulcers, rehospitalizations and medication use. Long-stay and short-stay residents are rated separately and combined. [11]

Flags CMS attaches to this home
- ⚑ High performing. Recognised by CMS for consistently high performance. [11]
How to read the numbers on this page
- Star ratings — 1 to 5 (no stars = not rated)
- 5 is much above average and 1 is much below average, compared with other nursing homes. A home with too little data may have no rating.
- Health inspection score — 0 and up, lower is better
- Points added up from citations (see the scope and severity grid) and revisits. 0 means a clean record; the state table shows which scores earn which stars.
- Quality measure percentages — 0 to 100%
- The share of residents with an outcome, such as a fall with major injury. For most measures a lower percentage is better; for vaccination measures a higher percentage is better.
- Nurse hours per resident per day — Hours, higher is better
- Paid nursing time divided by residents. For example 4.0 means each resident gets about four hours of nursing care a day, shared across all shifts.
- Staff turnover — 0 to 100%, lower is better
- The share of nursing staff who left during the year. High turnover can mean less continuity of care.
- Case-mix index — Around 1.0 is typical
- How much care the residents need. Above 1 means sicker or more dependent residents who need more staff time.
- Fines — Dollars; payment denials in days
- Penalties CMS imposed for serious or repeated problems. A payment denial stops Medicare/Medicaid payment for new admissions.

Staffing & turnover
More nursing time per resident and a steadier team are both signs of better care. Hours come from payroll records the home submits to CMS each quarter.
Nurse hours per resident per day, by role
A resident's day is 24 hours; this is how much paid nursing time each resident gets, shared across all shifts.
RN 0.28 · LPN 0.84 · Nurse aide 2.54. What the home's payroll records show.
RN 0.64 · LPN 0.80 · Nurse aide 2.18. What CMS predicts a home with these residents' needs would staff.
RN 0.30 · LPN 0.90 · Nurse aide 2.72. The reported hours rescaled so homes with sicker or healthier residents can be compared fairly.

Inspections
State inspectors visit each home about once a year and investigate complaints. Every problem they cite is a deficiency, lettered A to L by how serious and how widespread it was.
Health inspection score
31.0 points — in CA that earns (Much above average).
Lower is better. The score adds up points for every citation (more for serious, widespread problems) and for revisits needed to confirm fixes, then weights recent inspections most. [11]

Resident quality measures
These measure what actually happens to residents, as a percentage from 0 to 100 (or events per 1,000 resident days). For almost all of them a lower number is better; the vaccination measures are the exception and are marked. A star means the measure counts toward the quality star rating.
