Post-acute care refers to the care that a patient receives after being discharged from an acute care hospital. It is often provided to individuals who need continued medical care, rehabilitation, or support services following a hospital stay.

SNFs are healthcare facilities that provide skilled nursing care and rehabilitation services. They are designed to care for individuals who require a higher level of medical care than what is available in other settings, such as nursing homes or assisted living facilities.

Sub-acute rehabilitation involves a level of care that is less intense than acute care but more specialized than traditional long-term care. It often includes rehabilitation services to help patients recover from surgery, illness, or injury.
