One of the 3 E’s from the hugely influential monograph: Cochrane, A. L. (1972). Effectiveness and efficiency. Random reflections on health services. Nuffield Provincial Hospitals Trust.

In Cochrane’s terms effectiveness of an intervention was what you needed assuming you had shown efficacy (q.v.!) It is the practicality of the intervention: can it be delivered realistically in routine practice and does it continue to work well in those conditions as opposed to the rather unrealistic conditions of efficacy studies.
To a large extent this was the driver behind my involvement in developing the CORE system and the broad idea of Practice Based Evidence (PBE) for psychosocial interventions.
