acuity

How ill a client is and how much nursing care they need; in an eye exam, how sharply a person sees.

uh-KYOO-ih-tee noun

What it means

In nursing management, acuity describes the severity of a client's condition and the amount of care needed. Units use acuity to plan staffing and make assignments, giving nurses with high-acuity clients fewer clients. Visual acuity, a separate meaning, is measured with an eye chart such as the Snellen chart (20/20 is normal).

For the nurse

When making assignments, balance acuity across staff. A client's acuity can change quickly, so assignments may need to change during a shift.
