Overview of Mount Sinai South Nassau Mount Sinai South Nassau runs a 20-bed transitional care unit tucked inside its own hospital in Oceanside, Nassau County. Sitting just 0.6 miles from the city center, the location scores 72 on the Walk Score index, meaning most daily errands don’t require a car.
This is a nursing home hospital unit that opened in 2014 and now runs at 85 percent occupancy, housing 15 residents at a time. Because it’s built into an acute-care hospital, the model here is short-term: get people well enough to leave the hospital system entirely, whether that means going home or moving to a different long-term setting. Physical therapy, occupational therapy, and skilled nursing form the clinical core, and none of it happens in isolation. Cardiology, oncology, orthopedics, and pain management specialists sit on the same campus, so a resident needing a specialist consult doesn’t have to leave the building.
Staffing numbers back up that short-term, higher-acuity focus. Registered nurses provide 4 hours and 35 minutes of care per resident daily, and total nursing care comes to 5 hours and 9 minutes per resident per day. Medicare covers the entire resident payer mix here, which tracks with a unit built around post-acute rehab stays rather than long-term custodial care. Hospital eldercare and animal-assisted therapy round out the named programs, alongside religious services and a volunteer program for residents who want it.
State inspectors, through New York’s Office of Aging and Long Term Care, have tended to center their reviews on care planning and documentation. The facility is a unit built for a specific kind of stay: intensive, hospital-adjacent rehab for someone who just left acute care and needs a bridge back to independence or a longer-term placement, not a permanent home.
