Impairment and disability evaluation: the role of the family physician.

Physicians are frequently involved in the assessment of impairment and disability as the treating physician, in consultation, or as an independent medical examiner. The key elements of this assessment include a comprehensive clinical evaluation and appropriate standardized testing to establish the diagnosis, characterize the severity of impairment, and communicate the patient's abilities, restrictions, and need for accommodation. In some cases, a functional capacity evaluation performed by a physical or occupational therapist or a neuropsychological evaluation performed by a neuropsychologist may be required to further clarify the functional capacity of the patient. The results of the impairment evaluation should be communicated in clear, simple terms to nonmedical professionals representing the benefits systems. These individuals make the final determination on the extent of disability and eligibility for benefits and compensation under that particular benefits system.
