But nurses and hospital workers said the attacks leave physical and emotional scars that drive badly needed colleagues out of the profession. Minnesota hospital and union leaders said the data is skewed because the state has a culture of reporting adverse events, which likely increased its total of worker assaults compared to others. The Minnesota Nurses Association (MNA) raised alarm over attacks at Essentia Health hospitals in Duluth and Brainerd that injured four nurses in two weeks last October. Changes in the federal data prevented a comparison over time of the violence data, though. A report sent to lawmakers this week showed all Minnesota hospitals submitted prevention plans by an initial deadline, though five smaller hospitals needed reminders of the new requirement.
