Overview of Mount Sinai South Nassau

Mount Sinai South Nassau Transitional Care Unit is a 20-bed nonprofit transitional care unit in Oceanside, Nassau County, located within Mount Sinai South Nassau Hospital.

Automatic sprinkler systems and fire safety compliance protect residents. The unit specializes in rehabilitating patients transitioning from acute hospital care, enabling efficient progression toward discharge or placement in appropriate long-term care settings.

The hospital’s on-campus location eliminates transportation barriers for post-acute patients requiring physician oversight and diagnostic services. Cardiologists, oncologists, orthopedic surgeons, and specialists remain immediately available for resident care coordination.

Mount Sinai South Nassau Transitional Care Unit is exceptionally well-suited for patients requiring high-intensity post-acute rehabilitation with access to comprehensive hospital services, exceptional five-star quality ratings, and staffing levels substantially above national norms.

Staff typeHours / Day / Residentvs state avg
Registered Nurse (RN) Info RNs hold the highest nursing license and can assess residents, interpret test results, and direct care plans. More RN hours per day often signals stronger clinical oversight and faster response to health changes. 4h 35m per day ▲ 554% State avg: 42m per day · National avg: 41m per day
LPN / LVN Info Licensed Practical Nurses (LPNs) or Licensed Vocational Nurses (LVNs) deliver routine hands-on care — medication administration, wound dressing, and monitoring vital signs. They work under RN supervision and make up a large share of daily bedside care. 0m per day ▼ 100% State avg: 47m per day · National avg: 52m per day
Nurse Aide Info Certified Nurse Aides (CNAs) provide the most direct day-to-day assistance: bathing, dressing, feeding, and mobility.

Weekend RN Info Registered nurse hours specifically on weekends. Facilities sometimes reduce RN presence on Saturdays and Sundays — a low weekend RN figure compared to weekday hours can indicate reduced clinical oversight when most administrative staff are absent. 3h 10m per day ▲ 566% State avg: 29m per day · National avg: 29m per day
