Ratings & measures

Tap a row to see what it means
Health inspection ratingCMS stars from the last three on-site inspection cycles1★Lowest tier among peersMA avg2.9★U.S. avg2.8★
What is health inspection rating?

Stars assigned from the last three standard surveys and every complaint investigation in that window, weighted toward the most recent and the most serious findings. CMS assigns these stars relative to other facilities in the same state.

Why it matters

It carries the most weight in the overall rating and is the only domain based on what trained inspectors saw on site rather than what the facility reported.

Staffing ratingCMS stars from payroll-reported hours and turnover3★Above only 39% of peersMA avg2.9★U.S. avg2.9★
What is staffing rating?

Nurse and aide hours per resident day from payroll records CMS collects every quarter, adjusted for how much care residents need, plus staff turnover and weekend coverage.

Why it matters

More hours and lower turnover are the strongest predictors of fewer falls, pressure sores, and avoidable hospital stays.

Quality measures ratingCMS stars from clinical outcomes and resident assessments2★Above only 9% of peersMA avg3.3★U.S. avg3.6★
What is quality measures rating?

Clinical outcomes from resident assessments and Medicare claims: falls with injury, pressure ulcers, hospitalizations, antipsychotic use, and more, for both short-stay and long-stay residents.

Why it matters

It shows whether care is working, but part of it comes from the facility’s own assessments, so read it alongside the inspection results.

Total nurse hoursPer resident per day, all nursing staff4.06hrsAbove 78% of peersMA avg3.86Benchmark4.10
What is total nurse hours?

All licensed nurse and aide hours worked, divided by the number of residents, on an average day. Reported from payroll, not self-reported.

Why it matters

Federal research links 4.1 hours a day to fewer avoidable harms. Below about 3 hours, residents wait longer for help with basics like toileting and repositioning.

RN hoursPer resident per day, registered nurses only0.40hrsAbove only 12% of peersMA avg0.65Benchmark0.75
What is rn hours?

Registered nurse hours only. RNs assess residents, manage medications, and catch changes in condition; LPNs and aides deliver most hands-on care.

Why it matters

RN coverage is the staffing measure most tied to fewer hospital transfers and infections, and it is where thinly staffed facilities cut first.

Nursing staff turnoverShare of nursing staff who left within a year · lower is better58%Above only 6% of peersMA avg39%RN turnover40%
What is nursing staff turnover?

The share of nursing staff who left within the past year, from the same payroll data.

Why it matters

High turnover means residents are cared for by people who do not know them, and it is one of the strongest predictors of inspection problems.

Fines in the last three yearsCivil money penalties imposed by CMS · lower is better$16,945Above only 35% of peersMA avg$39,993Fines · denials1 · 0
What is fines in the last three years?

Civil money penalties CMS imposed after serious or uncorrected deficiencies, and denials of Medicare payment for new admissions.

Why it matters

Penalties follow the worst inspection findings. A recent fine is the clearest sign that inspectors found real harm.
