Chapter 2: Practical Application of the AMA Guides

• Introduction
  • Description of changes: revised to reflect the evidence-based editorial process and AMA H-365.976
  • Deletion: The Guides is written by medical doctors for medical doctors and others permitted to do impairment evaluations. 
  • Insertion: The AMA Guides is written by physicians for conducting impairment evaluations. Physician is defined as an individual who has received a Doctor of Medicine or a Doctor of Osteopathic Medicine degree or a recognized equivalent physician degree and who would be eligible for an Accreditation Council for Graduate Medical Education (ACGME) residency.
• Table 2-1 Fundamental Principles of the AMA Guides (#6)
  • Deletion: “Impairment evaluation requires medical knowledge. Physicians duly recognized by an appropriate jurisdiction should perform such assessments within their applicable scope of practice and field of expertise.”
  • Insertion: “Impairment evaluation requires medical knowledge. Physicians, chiropractors, and others permitted to do impairment evaluations recognized by the relevant jurisdiction perform impairment evaluations within their applicable scope of practice and field of expertise and calculate impairment ratings utilizing the AMA Guides.”
• Section 2.3a Who Performs Impairment Ratings?
  • Deletion: Impairment evaluation requires medical knowledge; therefore, mostly doctors who are qualified in allo pathic or osteopathic medicine or chiropractic medicine use the Guides to evaluate permanent impairment. For the purpose of determining impairment, the appropriate health regulatory agency in a given jurisdiction is the best-suited authority to determine the definition of doctor in regard to who uses the Guides to rate impairment in that jurisdiction.

    It must be emphasized, however, that even though the Guides is mainly written by medical doctors for medical doctors and others permitted to do impairment evaluations, nonphysician evaluators may analyze an impairment evaluation to determine if it was performed in accordance with the Guides.
