Researchers analyzed patient discharge data and hospital characteristics, as well as patient and nurse survey data, across adult acute care hospitals in six European countries. After adjusting for hospital and patient variables, they found that hospitals in which nursing care was provided to a greater degree by skilled nurses had lower odds of mortality. The authors argue against replacing professional nurses with nursing assistants and suggest that doing so may compromise patient safety by increasing preventable deaths.
