Registered nurses in expanded roles improve care in nursing homes: Swiss perspective based on the modified Delphi method.

The identified competencies clarify the duties of expanded-role registered nurses, thereby differentiating them from other care providers. Although conducted in the Swiss healthcare system, our methods and findings can be adapted to other healthcare settings. The results of this study will guide the development of an educational programme in a multi-centre study to reduce avoidable hospitalizations, while the defined outcomes guide the evaluation of their impact.
