Abstract
Who is in the better position to evaluate, the treating physician or an independent medical examination (IME) physician? A treating physician has a patient-advocate role because he or she has a doctor-patient relationship with the patient/claimant. Unlike the treating physician, an IME physician does not have a doctor-patient relationship, and can, therefore, provide an impartial evaluation necessary to assess the extent to which the patient/claimant is impaired or disabled from functional activities of daily living.
Abstract
Physicians performing impairment evaluations on patients with cognitive complaints and possible central nervous system disorders should perform a clinical mental status assessment. Assessing cognitive complaints efficiently, in a systematic and supportable way, can be challenging. The AMA Guides to the Evaluation of Permanent Impairment specifies that objective criteria are important to consider when assessing impairment. Physicians may choose to use standardized cognitive screening tests (cognitive screeners) as a relatively quick, practical tool to initially assess patients and aid in decision making. Several cognitive screeners will be discussed in detail below. A patient's performance on such tests may indicate that more comprehensive testing is needed. Cognitive screeners have limitations and are not designed to assess symptom validity or the extent to which psychological factors may contribute to cognitive complaints. Comprehensive neuropsychological assessment may be indicated in these situations and when the screeners demonstrate findings of potential concern help define MMI.
Abstract
Complex regional pain syndrome (CRPS) is characterized by chronic spontaneous and/or evoked regional pain disproportionate in severity, distribution, and/or duration to that typically experienced after a similar injury or illness. The pain may also begin without a known precipitant. While various authors have questioned the validity of the diagnosis, physicians will be asked to perform impairment ratings on patients diagnosed with CRPS. Hence, it is important to understand the issues associated with this syndrome; the diagnostic criteria for it, including the need to rule out other diagnoses that may explain the patient's presentation; and how to rate CRPS. The AMA Guides to the Evaluation of Permanent Impairment, Fifth Edition, provides approaches to assessing CRPS impairment that are refined in the Sixth Edition.
Abstract
Patients with coronavirus disease 2019 (COVID-19) may have persistent symptoms beyond the normally expected illness resolution. This disease was not diagnosed before late 2019, and therefore, we have more limited experience in understanding all of its outcomes. Thus, clinical, functional, and permanent impairment assessment is challenging. Symptoms including fatigue, dyspnea, and cognitive difficulties have been referred to as “post-acute COVID,” “long COVID,” or “long haulers.”
Patients who present for assessment of causation, maximum medical improvement (MMI), and permanent impairment can be challenging. For some examinees, after 6 to 12 months without outgoing improvement and with appropriate investigation, treatment, and rehabilitation, the examinee can be considered at MMI. However, because this disorder is new and appropriate treatment may be unclear, the time to achieve MMI is less certain. Physicians may use approaches in the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), to help define MMI. As science evolves, so will our understanding of how to evaluate chronic problems associated with COVID-19.
Abstract
Nerve lesions caused by traumatic events to the lower extremity's peripheral nerves are rated using Section 16.4 of the sixth edition of the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides). Results from sensory and motor nerve tests are used to assign the impairment class within Table 16-12, Peripheral Nerve Impairment (6th ed, 534). The default rating may be modified with the functional history and clinical studies modifiers, but not the physical examination modifier, because it is used to assign the impairment class and define the degree of neurologic severity. Impairment for both sensory and motor deficits are assigned and then combined at the lower extremity level.
