A skilled nursing facility (SNF) is a licensed healthcare center that provides short-term medical care and rehabilitation for patients recovering from a hospital stay or needing continuous supervision beyond what can be handled at home.

The Social Insurance (Bismarck) Model is a healthcare financing system based on solidarity and shared risk. It is funded through employer and employee contributions paid into non-profit insurance funds, which provide universal coverage while care is delivered by private providers under centralized regulation.

Enacted in 1935, the Social Security Act provides benefits for old-age retirees, dependent mothers and children, the jobless, victims of work-related accidents, blind people, and people who have physical disabilities.
