In an essentially applied area of research, there are particular pressures on health services and policy researchers to describe the impact of their work. However, specialized research impact assessments often require skills and resources beyond those available to individual researchers, and ad hoc accounts impose a considerable burden to generate. Further, these idiosyncratic accounts may not facilitate comparative analysis to inform research management, practice and assessment. This paper describes an initial attempt to develop a methodical approach to identify and describe research impact.
