What health inspectors found (on-site government inspections — the most independent evidence available)

Health inspection rating: ★★★★★5/5 · CMS overall rating: 5/5

⚠ The most recent standard health inspection was more than 2 years ago — conditions may have changed.

The health inspection star above is graded on a curve within each state — a set share of each state's facilities gets each star level — so a facility can have few citations and still rate 2–3 stars if others in its state did even better. The overall rating combines that inspection score with staffing and self-reported quality measures.

All citations in the current public record (8)

CMS publishes roughly the last three inspection cycles plus recent complaint investigations. Older surveys drop out of the record as new ones are completed.

Date	Severity	What the facility was cited for
Jul 6, 2021	E · Potential for harm, repeated	The facility did not get its food from approved, safe sources, or did not store, prepare, and serve food according to professional food safety standards.
Jul 6, 2021	D · Potential for harm, one-off	The facility did not develop a resident's complete plan of care within 7 days of the full assessment, or the plan wasn't prepared, reviewed, and updated by a team of health professionals as required.
Jul 6, 2021	D · Potential for harm, one-off	The facility did not provide treatment and care that follows the doctor's orders and matches the resident's own preferences and goals.
Jul 6, 2021	D · Potential for harm, one-off	The facility did not provide enough food and fluids to keep residents healthy, such as preventing unplanned weight loss or dehydration.
Jul 6, 2021	D · Potential for harm, one-off	The facility did not have a licensed pharmacist review each resident's complete medication regimen and medical chart every month, or did not follow its own rules for reporting medication problems.
Jul 6, 2021	D · Potential for harm, one-off	The facility did not try to gradually reduce doses of mood- and mind-altering medications or use non-drug approaches first, as required, or used 'as needed' psychiatric drugs without proper limits.
Jul 6, 2021	D · Potential for harm, one-off	The facility was not properly licensed, or did not operate in compliance with federal, state, and local laws, regulations, and accepted professional standards.
Jul 6, 2021	D · Potential for harm, one-off	The facility did not have or follow an effective program to prevent and control infections — such as proper hand washing, cleaning, and isolation practices. This is the most commonly cited deficiency nationwide.

Nurse staffing (from payroll records, adjusted for how much care residents need)

Measure	This facility	New York avg	U.S. avg	Where it stands
Total nurse staffing (hours per resident per day)	5.07	3.58	3.95	top 4% in New York; top 12% in the U.S.
Registered Nurse hours	1.91	0.68	0.69	top 2% in New York; top 2% in the U.S.
Weekend total nurse staffing	4.61	3.13	3.50	top 4% in New York; top 10% in the U.S.
Weekend RN hours (not acuity-adjusted)	1.38	0.48	0.48	top 3% in New York; top 2% in the U.S.
Total nursing staff turnover (%)	24.0	40.3	45.8	top 12% in New York; top 6% in the U.S.
RN turnover (%)	12.5	39.8	42.9	top 3% in New York; top 6% in the U.S.

Hours are per resident per day, case-mix adjusted by CMS so facilities caring for sicker residents can be compared fairly (same basis as the CMS staffing star). "Top X%" means better than most facilities: more staffing hours, or lower turnover. Raw (unadjusted) reported hours: total 4.70, RN 1.78, weekend 4.28. Staffing rating: 5/5.

Self-reported quality measures

Note: these ratings are based on data the facility reports about itself to CMS. They are not independently verified by inspectors, and can look better than inspection findings. Give more weight to the inspection results above.

Quality measures rating: 4/5 · long-stay residents: 2/5 · short-stay residents: 5/5
