Impairment Tutorial: Consistency in Measurement

Abstract

Abstract The International Association of Industrial Accident Boards and Commissions (IAIABC) is an organization of medical directors, administrators, and administrative law judges for workers’ compensation systems. It was founded in 1914, and current membership represents 41 US states, the District of Columbia, Puerto Rico, 9 Canadian provinces, and 3 other governments in a forum for education and discussion regarding the various medical, legal, and administrative issues in workers’ compensation systems. In 2001, the IAIABC formed an Occupational Impairment Rating Guide Committee to study the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) and to suggest revisions specific to workers’ compensation. The committee's goal is to create a supplement to the AMA Guides for jurisdictions to consider for adoption to clarify and/or to replace methodology in the AMA Guides to make impairment rating more uniform and consistent. The IAIABC Guides has been developed to address impairment of the musculoskeletal system and impairment due to chronic pain with the goal of minimizing or eliminating the need for multiple independent medical evaluations and “dueling doctor depositions.” There are no plans to write supplemental guides for impairment of other body systems, and AMA and IAIABC are engaged in active dialog during the development of the AMA Guides, Sixth Edition.
