Across the nation, states are grappling with alternative approaches to address the heightened problem of low nurse staffing in hospitals. A new national study finds that while legislation to mandate hospital nurse-to-patient staffing ratios is associated with a significant increase in nurse staffing, two other popular approaches—mandating public reporting of nurse staffing levels and hospital staffing committees that include frontline nurses—have had little or no impact on nurse staffing levels. The study appears in a special supplement to the October issue of Medical Carefocused on Health Workforce Equity.
