Does increased RN staffing reduce hospital related mortality and adverse patient events?
Does increased RN staffing reduce hospital related mortality and adverse patient events?
Increased registered nurse staffing is associated with lower odds of hospital-related mortality and adverse events.
Supports higher RN ratios in policy; leaves open causality pending RCTs.
Studies with different design show associations between increased RN staffing and lower odds of hospital related mortality and adverse patient events. Patient and hospital characteristics, including hospitals' commitment to quality of medical care, likely contribute to the actual causal pathway.
