A multi-dimensional model of clinical utility

Clinical utility is an increasingly used concept in health care, but one that lacks an agreed formal definition or conceptualization. In this article, I show that the term is commonly used as a synonym for studies of clinical effectiveness and/or economic evaluations and argue that further factors relating to everyday working practice should be included under its auspices. I go on to develop a multi-dimensional model that outlines four factors in practitioners' judgements about clinical utility: appropriateness, accessibility, practicability, and acceptability.
