Data insights
Quality ratings
CMS's most recent Care Compare release (data as of April 2026) puts Care One at Brookline's overall quality rating at 2 out of 5 stars, a composite of three sub-ratings: health inspection (2/5), staffing (3/5), and quality measures (4/5).
What each sub-rating measures
The health inspection rating reflects on-site surveyor findings from the last three cycles. The staffing rating compares case-mix-adjusted nurse hours per resident day to national benchmarks, and quality measures aggregate 15 clinical indicators including pressure ulcers, falls with injury, and long-stay antipsychotic use.
Size and setting
Located in Brookline, Massachusetts, this facility operates 120 certified beds with an average daily census of roughly 91 residents - an occupancy rate of about 76%. The facility is classified under for profit - limited liability company ownership, a designation that can influence staffing patterns, reinvestment decisions, and admissions policy. At roughly 76% occupancy, this facility has meaningful open capacity relative to its certified bed count.
Same-ownership peers
Within Massachusetts, Care One at Brookline is one of 148 for profit - limited liability company nursing homes CMS rates. Its 2-star overall rating sits below the for profit - limited liability company-segment average of 2.6 stars, ahead of roughly 29% of same-ownership peers in the state. Comparing a facility against its own ownership segment holds the business model roughly constant, which helps isolate facility-level performance from the staffing and reinvestment patterns that differ across for-profit, non-profit, and government operators.
Inspection record
On the regulatory side, federal and state surveyors have documented multiple deficiencies at this facility (51 total). CMS has levied no enforcement penalties over the equivalent window. This is a high deficiency count relative to most facilities; requesting the full survey report directly is the only way to see whether these are concentrated in one area or spread across the facility's operations.
Where these figures come from
The figures above come directly from the U.S. Centers for Medicare \& Medicaid Services Nursing Home Compare dataset for federal quality ratings, combined with the CareScout 2025 Cost of Care Survey of more than 15,000 elder-care providers nationwide and U.S. Census American Community Survey income data. Cost figures are monthly medians, refreshed annually with each new CareScout release; quality ratings are refreshed quarterly from the CMS Provider Information File. Read these state and county medians as benchmarks, then verify current rates with individual providers and consult care managers before making placement decisions.
