Evidence-based practice (EBP) requires the conscious, conscientious and explicit application of the best available research evidence, together with professional expertise and patient/customer choice, to work practices. From its origins in clinical medicine, through a broader application to the health services industry, an evidence-based approach to work practices is becoming increasingly influential in all human services. Implementing evidence-based practice is related to the organisational management concepts of Continuous Quality Improvement (CQI), Knowledge Management and the Learning Organisation. For human services professionals finding, critically appraising and applying best evidence requires enhanced information and knowledge management skills. Central to these skills is an understanding of the information ecology, particularly for the multi-disciplinary AOD field.

This paper introduces the data-information-knowledge continuum, levels of evidence and the tools and techniques of finding and critically appraising evidence. Examples relevant to the AOD field are provided.
