ctude
A ctude is a care assessment and evaluation instrument, a composition that is usually short, in summary form comprised of key concepts, and yet capable of representing the complexity of health and social care contexts. The ctude is designed to provide practice material for developing expertise in care assessment, holistic and integrated care that is also person-centred. Coined from étude (/ ˈeɪtjuːd /; French pronunciation: [eˈtyd], a French word meaning study) it is a study in care and can be a snapshot, or a dynamic series.
