Nursing Theory in the Quest for the Sustainable Development Goals.

The 17 United Nations Sustainable Development Goals (SDG) are intended to promote a safe, healthy, and equitable world by the year 2030. Nurses are at the forefront of realizing the 2030 agenda through concerned citizenship and professional leadership. Nursing theory informs knowledge development and theory-guided practice essential for nurses working in all domains and in all nations. Although all extant nursing theories are relevant, a select few are discussed in detail to make explicit the links between theory and SDG realization. Middle-range theories are also valuable in helping to contextualize nursing practice through the lens of the SDGs. The SDGs address five themes - People, Planet, Peace, Prosperity, and Partnership - and theory remains vital to ensure nurses working in all settings are equipped to meet the needs of humanity and the world, now and in the future.
