Increases in hospital nurse staffing levels are associated with reductions in adverse events and lengths of stay and do not lead to increased costs.
Researchers also found that increasing the number of registered nurses, as opposed to other nursing positions, led to reduced costs.
The findings suggest increased staffing of registered nurses can improve patient outcomes and efficiency.
