Mount Sinai South Nassau is a nursing home in Oceanside, NY. Nursing home care includes ongoing nursing oversight and help with daily care, making the home a possible fit for a loved one who needs continuing support. There are 455 beds, so this is a large setting with more residents, staff and usually more programming than a small community.
Total nurse staffing is 5 hours and 55 minutes per resident each day. That figure represents the daily hands on nursing time associated with each resident. Staff are available throughout the day and night, providing round the clock coverage.
Rehabilitation services allow therapy to be part of a resident’s care at the facility. A hospital eldercare program and animal assisted therapy are also available, giving residents access to those additional forms of support. Religious services provide opportunities for worship or spiritual support.
Mount Sinai South Nassau accepts residents who need this level of care in an acute care, not for profit teaching hospital setting.
Quality ratings
The Overall CMS Rating combines results from health inspections, staffing levels and quality measures. Health inspections carry the most weight. Staffing and quality scores can increase or decrease the final rating based on performance compared to state and national standards.
Based on the results of the facility's three most recent standard inspections and any complaint investigations. CMS reviews the number, scope, and severity of deficiencies, with more recent findings weighted more heavily.
Measures average nursing staff hours per resident per day, including Registered Nurses (RNs) and total nursing staff. Ratings are adjusted based on the level of care residents require and are compared to state and national benchmarks.
Based on clinical and physical health indicators reported to CMS, such as hospital readmissions, falls, pressure ulcers, and improvements in mobility. These measures reflect how well residents' health needs are being managed.

CMS (Centers for Medicare & Medicaid Services, the federal agency that regulates nursing homes) Overall 5-star rating — a composite of Health Inspection, Staffing, and Quality Measures scores. 5 stars = top 10% nationally. 1 star = bottom 10%. The single most important number to start with when comparing facilities.
|
Care Types in This Table
AL (Assisted Living):
Housing with help for daily activities like bathing, dressing, and medication, without 24-hour skilled nursing.
NH (Nursing Home):
24/7 skilled nursing care for residents with complex, ongoing medical needs.
SNF (Skilled Nursing Facility):
Round-the-clock nursing care, often for recovery after surgery, injury, or illness.
MC (Memory Care):
Secured, specialized care for people living with Alzheimer's or dementia.
RC (Respite Care):
Short-term temporary care that gives family caregivers a break.
HOS (Hospice Care):
Comfort-focused care for those with a terminal illness, prioritizing quality of life over treatment.
PC (Palliative Care):
Comfort-focused care for serious illness at any stage, including alongside curative treatment.
|
Neighborhood or city area where the facility is located. Proximity to family, hospitals, and green space matters for both quality of life and ease of visitation. Consider drive time and transit access when evaluating location.
|
Licensed bed capacity. Larger facilities (300+ beds) often have more specialized programs but can feel institutional. Smaller homes (under 150 beds) tend to deliver more personalized care. Compare with Avg Res/Day to understand how full the facility typically runs.
|
Percentage of licensed beds filled on an average day. Color indicates financial health: green (90%+) = operationally strong, typically profitable. Amber (80–89%) = stable but leaving revenue on the table. Orange (70–79%) = financial strain likely, may struggle with fixed costs. Red (<70%) = significant distress, closure or ownership change risk increases sharply.
|
This facility's occupancy rate compared to the statewide average for similar facilities. A positive number means above-average demand. Facilities running 5%+ above the state average are typically the most sought-after in their market — a strong proxy for reputation.
|
CMS-adjusted total nurse hours per resident per day (RN + LPN + CNA combined). The national average is approximately 3.5 hrs. Higher is better — more direct care time per resident. Below 3.0 is a red flag. CMS weights RN hours more heavily because RNs handle complex clinical decisions that CNAs cannot.
|
CMS Health Inspection star rating (1–5 stars), based on the 3 most recent annual state surveys plus any complaint investigations. This is the hardest rating to manipulate — it reflects real surveyor findings on-site. 5 stars = fewest deficiencies found. 1 star = most. It carries the heaviest weight in the Overall CMS rating.
|
CMS Staffing star rating (1–5 stars), based on daily nurse staffing hours submitted to CMS via verified payroll data. Compares RN, LPN, and CNA coverage relative to resident acuity level. 5 stars = well above expected staffing. Weekend staffing is evaluated separately, as that's where many facilities quietly reduce coverage.
|
CMS Quality Measures star rating (1–5 stars), based on 15 clinical outcome metrics including fall rates, pressure ulcers, antipsychotic drug use, and hospital readmissions. Captures actual resident health outcomes, not just compliance. High QM combined with low Health Inspection scores can indicate a facility with strong care but weak documentation practices.
|
Registered Nurse hours per resident/day compared to the statewide average. RNs are the highest-skilled nursing staff — they assess residents, manage medications, and respond to emergencies. A value of +50% means RN coverage is 50% above the state norm. Negative values are a concern for residents with complex or acute medical needs.
|
Total nursing staff hours (RN + LPN + CNA combined) per resident/day vs. the statewide average. A broader measure than RN vs State — it captures the entire care team. A facility can have high total staffing but low RN hours, meaning more aides and fewer nurses. Read both columns together for the full picture.
|
Total dollar amount of federal monetary fines (civil money penalties) issued by CMS in the past 3 years. Fines are only levied for serious violations — typically actual harm to residents, repeated uncorrected deficiencies, or systemic non-compliance. Even a single fine is noteworthy. Multiple fines strongly suggest a pattern, not isolated incidents.
|
Total health deficiency citations from the most recent standard inspection cycle. Minor citations (scope A–C) are common and often administrative in nature. Higher counts aren't always disqualifying, but should be read alongside Severe Citations to understand actual harm levels. Under 10 is strong for a large facility; 30+ warrants a closer look.
|
Average deficiency citations per CMS inspection (survey) in the reporting window — total citations divided by the number of inspections. Lower is better; compare alongside total Citations and Severe Citations for context.
|
Citations at CMS scope/severity level G or higher — G–I means actual harm occurred; J–L means residents were placed in immediate jeopardy. (D–F is potential for harm only). Examples include unaddressed falls, medication errors causing injury, neglect, or abuse.
|
Average number of residents in the building on any given day, derived from annual census data. Reflects true operating scale — a 400-bed facility running 200 residents/day operates very differently from one at 390. Higher resident counts generally mean more funded staffing hours.
|
Better Business Bureau rating (A+ to F). Reflects complaint history, business transparency, and how family disputes were resolved. A+ means no significant unresolved complaints. A blank (—) means the facility isn't BBB-accredited, which is common for healthcare providers and not necessarily a negative signal.
|
Walk Score® (0–100). Measures walkability of the surrounding area. 90–100 = Walker's Paradise. 70–89 = Very Walkable. 50–69 = Somewhat Walkable. Below 50 = Car-Dependent. Higher scores benefit family visitors, resident outings, and staff commuting.
|
The licensed owner or operator of record filed with CMS — the individual or organization legally accountable for the facility. Searching the operator name across other facilities can reveal chain or multi-site ownership, which matters: chain-operated homes tend to have more variable quality outcomes than independently run facilities.
|
What the home actually collects for resident care, after contractual allowances, bad debt and discounts — not gross billings. Taken from the latest complete annual cost report, so it is comparable across homes reporting the same period. Revenue alone doesn't indicate care quality, but it funds staffing and capital reinvestment. Pair with Payroll %. Figures are from each facility's most recent complete fiscal year — hover a value for the exact year; a * marks homes that report an older period than most facilities.
|
Staff salaries plus wage-related benefits from the latest complete annual cost report. Contract and agency labour is counted separately, under other operating costs, so a home leaning on agency staff can show a low figure here. Payroll is the cost most directly tied to care quality — compare with Payroll % for full context. Figures are from each facility's most recent complete fiscal year — hover a value for the exact year; a * marks homes that report an older period than most facilities.
|
Payroll as a share of NET PATIENT REVENUE (not gross revenue). Both figures come from the same cost-report year. A higher figure means more of each revenue dollar goes to staff pay. Read with the Staffing star rating to judge whether spend translates into coverage — and note that homes whose patient revenue covers only part of their operation can read implausibly high. The New York average is: 56.1% Figures are from each facility's most recent complete fiscal year — hover a value for the exact year; a * marks homes that report an older period than most facilities.
