Evaluating mastery of biostatistics for medical researchers: need for a new assessment tool.

Research training has enabled academic clinicians to contribute significantly to the body of medical research literature. Biostatistics represents a critical methodological skill for such researchers, as statistical methods are increasingly a necessary part of medical research. However, there is no validated knowledge and skills assessment for graduate level biostatistics for academic medical researchers. In this paper, I review graduate level statistical competencies and existing instruments intended to assess physicians' ability to read the medical literature and for undergraduate statistics for their alignment with core competencies necessary for successful use of statistics. This analysis shows a need for a new instrument to assess biostatistical competencies for medical researchers.
