The American Medical Association's Guides to the Evaluation
of Permanent Impairment, Fourth Edition, is the most commonly used
tool in the United States for rating permanent impairments for disability
systems. The Guides, currently undergoing revision,
has been the focus of considerable controversy. Criticisms have focused on
2 areas: internal deficiencies, including the lack of a comprehensive, valid,
reliable, unbiased, and evidence-based system for rating impairments; and
the way in which workers' compensation systems use the ratings, resulting
in inappropriate compensation. We focus on the internal deficiencies and recommend
that the Guides remains a tool for evaluation of
permanent impairment, not disability. To maintain wide acceptance of the Guides, its authors need to improve the validity, internal
consistency, and comprehensiveness of the ratings; document reliability and
reproducibility of the results; and make the Guides
easily comprehensible and accessible to physicians.
