Although increased CNA staff levels were associated with fewer injurious falls in NHs that were well staffed, increased CNA levels were associated with an increase in injurious fall rates in low-staffed facilities.

Efforts to improve quality outcomes in NHs through increasing staff hours may have a variable effect depending on an NH's baseline resource availability.
