Chapter 10 Determination of Disability Flashcards
KEY POINTS 1. Disability is a vaguely defined term that describes the inability to perform specific tasks or functions. 2. Impairment is an objective loss of function due to an injury or disease process. 3. Pain specialists require an understanding of disability terminology to provide objective ongoing or independent assessments of pain patients with disabilities and impairments
In theory, the determination of disability should be
a transparent, unprejudiced, and objective process, and impairments or functional limitations should be correlated with objective evidence for tissue damage, organ dysfunction, or cognitive dysfunction, and this evidence should be reproducible in examination or diagnostic study
Disability
is an alteration in one’s physical or cognitive
capacity to perform a specific task, function, or activity and
is highly dependent on individuality and context
Impairment
is an objective term that defines the loss or loss of use or derangement of any body part, organ system or organ function, but can also relate to impairments of cognitive
or psychological functioning. Impairment may be temporary or permanent, and can be reproducibly measured through testing or physician assessment
Handicap
is a legal or policy term used to describe a disability.
An impairment rating or whole person impairment
is a specific and objective
assessment of a patient’s impairment, and can be derived by using the American Medical Association’s Guides to the
Evaluation of Permanent Impairment. This rating defines the impact of an impairment on one’s ability to perform typical activities of daily living, including self-care, personal hygiene,
use of hands, ability to communicate, sensory functioning, sexual function, and ability to travel.Overall, the greater and more impactful the impairment is, the larger the whole person impairment percentage will be.
Maximal Medical Improvement (MMI)
It is important to note that an impairment rating
should not be assessed until the patient has reached maximal
medical improvement (MMI). MMI is the state at which all potential healing, repair, and treatment has been completed, and the impairment is permanent and unlikely to change
significantly within the ensuing 1-year period
The Social Security Act defines disability as
“the inability to engage in any substantial gainful activity by reason of a medically determinable physical or mental
impairment which can be expected to result in death or has lasted or can be expected to last for a continuous period of
not less than 12 months.
Four categories of disability are possible
temporary partial; temporary total;
permanent partial; permanent total—and the work-related injury
can be physical or mental
Independent Medical Evaluation (IME)
An independent medical evaluation (IME) is a comprehensive assessment of a patient by a trained physician
The purpose of the IME
is to objectively assess the impact of an injury and subsequent disability on
the patient’s ability to function in a variety of domains, including
self care, work duty, leisure, or recreational activity.
The evaluating physician
The evaluating physician reviews the treatment to date, performs a physical examination, and reviews pertinent diagnostic
tests and procedure reports, and then comments on the current clinical status, relevant diagnoses, and whether
the patient is at MMI.
The IME report
The IME report should address causation of the injury and the relationship of the injury to the impairment, and any anatomic, physiologic, or psychological impairments should be identified or described, in addition
to the permanence of these impairments.
Functional limitations
defined as a lack of ability to perform an activity
within a normal human range as the result of a specific impairment, should be specifically addressed in an IME report
Components of an Independent Medical
Evaluation
Narrative history
Current clinical status
Results of physical exam and diagnostic studies
Causation of injury and relationship to job
MMI assessment
Pertinent diagnoses
Impairments and function limitations
Permanence of impairments
Analysis of job tasks
Assessment of patient ability to perform job tasks
Functional capacity evaluation (FCE) or work capacity evaluation (WCE)
are measures of a patient’s functional ability and are typically performed with a physical therapist or occupational therapist. Tolerances for sitting, standing, walking, bending, reaching, lifting, and climbing are typically assessed, with a specific emphasis on the ability to lift and carry specific weights. The outcome of the evaluations is highly dependent on the
patient’s motivation and effort, and is inherently subjective to the examiner, especially in chronic pain patients
