Evidence-based clinical occupational medicine: updating the ACOEM occupational medicine practice guidelines.

In this article, we review the evolution and application of evidence-based medicine and the results of the literature reviews and syntheses incorporated in the second edition of the guidelines. Our intent is to disseminate this information to practitioners treating injured workers and those managing and financing such care and disability management. Use of proven diagnostic, causality, testing, and treatment methods should markedly improve the quality of occupational medical care and make that care more cost effective.
