The IME Handbook
Part 4 in a Series by Dr. Steve Feinberg

 

 

Dear fellow WOEMA members, some of you may be interested in performing independent medical legal evaluations (referred to as an IME) in addition to evaluations done within the workers’ compensation system. WOEMA presented a symposium at the WOHC 2017 Maui annual meeting in which Dr. Christopher Brigham and I provided a copy of our book, The IME Handbook. This is installment part 4 from that book. As always, I am personally available to you via email to answer any questions ([email protected]). This 4th installment will cover the cover IME assessment, case summary, clinical impression & analysis, causation and apportionment, prognosis, maximal medical improvement, impairment, work ability, appropriateness of medical care, recommendations and disclosures.

Dr. Brigham has a website devoted to IME education. While you will have access through the WOEMA Newsletter to the full IME Handbook in installments, the full IME Handbook PDF is available on his website as well. There is a cost associated with Dr. Brigham’s materials.

 

Assessment

Based on the findings from the history, review of medical records and other documents, physical examination and clinical studies, the evaluator responds to the specific questions asked by the client.

The evaluation physician cannot base opinions solely on only the basis of “education, training and experience.” Rather, the evaluator must provide a clear description of why a conclusion has been reached, including reference to the facts and current science and best practices.

Opinions are stated clearly and explicitly using terminology such as “based on a reasonable degree of medical probability.” This means “more likely than not”, i.e., that there is a probability greater than 50%. All opinions should be supported with a detailed explanation to justify those opinions.

Credibility issues should be discussed and explained. Do you believe the examinee is malingering (lying) or you find evidence of symptom magnification/exaggeration related to her chronic pain syndrome?

Case Summary

Provide a succinct summary of the history and physical examination followed by opinions (when requested) on the specific issues requested by the client. 

Clinical Impression

List the diagnostic categories and/or the differential diagnoses. Typically, this is done as a numbered list. Also, include the basis for your impression – findings in medical records, labs, imaging, current exam findings, etc.

Clinical Analysis

It is essential to provide a clinical discussion of the problems in a manner that is clearly understood by a non-medical reader. Your opinions must be supported by the facts in the case and evidence-based medicine. As appropriate, provide specific references to the medical literature.

Causation and Apportionment

Causation and apportionment are often critical issues. The evaluator must determine whether the problem, impairment and/or disability was preexisting or was caused by an event or occurrence. There may be multiple factors, including occupational and non-occupational, that contribute to the development of a clinical problem. Causation must be based on the facts and current science. Legal standards for causation may differ from medical standards and may vary by jurisdiction.

Many clinicians focus on aspects of clinical care for their patients, i.e., what is appropriate evaluation and treatment, and may not be formally trained in causation analysis or epidemiology, nor may they be familiar with the most current science. IME physicians must understand the current science and the process of determining whether a condition is injury-related. In the AMA Guides series of publications, the Guides to the Evaluation of Disease and Injury Causation provides guidance on the process of causation and apportionment analysis.[1] This publication provides guidance on understanding work-relatedness, methodology, causality examination, and provides chapters dealing with specific regions.

Causality requires determination that each of the following has occurred to a reasonable degree of medical certainty:

  • A causal event took place.
  • The patient experiencing the event has the condition (e.g., impairment).
  • The event could cause the condition.
  • The event caused or medically contributed to the condition within medical probability.

It appears that some physicians opine that certain injurious events caused or aggravated a condition based on a temporal relationship, without a scientific basis to support these conclusions, and these opinions are accepted by fact finders without further analysis. This results in faulty decisions on these cases and a failure of the examinee to understand the true nature of the condition.

In 1965, the English statistician Sir Austin Bradford Hill proposed a set of nine criteria to provide epidemiologic evidence of a causal relationship between a presumed cause and an observed effect or simply an association. This causation analysis checklist is sometimes referred to as the Bradford Hill criteria.[2]

The list of the criteria is as follows:

  1. Strength (effect size): A small association does not mean that there is not a causal effect, though the larger the association, the more likely that it is causal.
  2. Consistency (reproducibility): Consistent findings observed by different persons in different places with different samples strengthens the likelihood of an effect.
  3. Specificity: Causation is likely if there is a very specific population at a specific site and disease with no other likely explanation. The more specific an association between a factor and an effect is, the bigger the probability of a causal relationship.
  4. Temporality: The effect has to occur after the cause (and if there is an expected delay between the cause and expected effect, then the effect must occur after that delay).
  5. Biological gradient: Greater exposure should generally lead to greater incidence of the effect. However, in some cases, the mere presence of the factor can trigger the effect. In other cases, an inverse proportion is observed: greater exposure leads to lower incidence.
  6. Plausibility: A plausible mechanism between cause and effect is helpful (but Hill noted that knowledge of the mechanism is limited by current knowledge).
  7. Coherence: Coherence between epidemiological and laboratory findings increases the likelihood of an effect. However, Hill noted that “… lack of such [laboratory] evidence cannot nullify the epidemiological effect on associations”.
  8. Experiment: “Occasionally it is possible to appeal to experimental evidence”.
  9. Analogy: The effect of similar factors may be considered.

The evaluator must be able to distinguish between an aggravation and an exacerbation. An aggravation results from an event or injury causing a permanent worsening, hastening or deterioration of a pre-existing condition. An exacerbation is a temporary increase in the symptomatology of a pre-existing condition; in some jurisdictions, this is referred to as a temporary aggravation. It is important to understand the use of appropriate terminology in the jurisdiction/context in which you are working.

Medical apportionment is an estimate of the extent to which two or more probable factors caused an injury or disease. When apportioning responsibility for an injury or disease, one must first consider all potential causes and then determined whether each is probable or possible. A compensable injury or disease may exacerbate or aggravate a pre-existing condition, but may also be temporarily or partly worsened by subsequent trauma or exposure. Many illnesses are multifactorial in etiology. Physicians must be aware of the current medical literature to determine the causes for a condition, including occupational and non-occupational causes and the significance of these causes.

It is also important to recognize that the definition of apportionment depends on the jurisdiction.

Prognosis

Determine prognosis based on the clinical problems and probable future clinical course.

Maximal Medical Improvement (MMI)

The evaluator assesses whether a condition has stabilized and is unlikely to change (improve or worsen) substantially in the next year, with or without treatment. Synonyms include: fixed and stable, permanent and stationary and stable and ratable.

Impairment

Impairment evaluation is the acquisition, recording, assessment and reporting of medical evidence using a standard method such as that described in the AMA Guides to the Evaluation of Permanent Impairment. The appropriate Edition of the Guides should be used, based on the jurisdiction. The evaluation and reporting must comply with the standards provided in the Guides.

Work Ability

Work ability is defined by consideration by of three factors: risk, capacity and tolerance.[3] The IME physician needs to assess each of these factors in opining on work ability. Risk refers to the chance of harm to the examinee, co-workers, or to the public, if the examinee engages in specific work activities. Substantial harm means an objectively worsening in the examinee’s condition, and not merely an increase in previously present symptoms, like pain or fatigue. Capacity refers to concepts such as strength, flexibility and endurance. These are measurable with a fair degree of scientific precision. Current capacity may increase with exercise or the passage of time. Tolerance is a psychopathologic concept that refers to the ability to tolerate sustained work or activity at a given level. Symptoms such as pain and/or fatigue are what limits the ability to do task(s) in question. Tolerance is dependent on the rewards available for during the activity in question.

Appropriateness of Medical Care

When requested, the appropriateness of medical care should be evaluated using evidence-based medicine and recognized practice guidelines, such as the American College of Occupational and Environmental Medicine Practice Guidelines and/or Official Disability Guidelines – Treatment Guidelines.

Recommendations

The client may request recommendations on further medical care and/or steps to facilitate recovery. Some IME physicians may provide cost estimates but typically a separate Life Care Planner works with the IME on future medical care costs.

Disclosures

IME physicians commonly provide disclosures at the end of their reports, such as:

The above analysis is based upon the available information at this time, including the history given by the examinee, the medical records and tests provided, the results of pain status inventories, and the physical findings. It is assumed that the information provided to me is correct. If more information becomes available later, an additional report may be requested. Such information may or may not change the opinions rendered in this evaluation.

My opinions are based upon reasonable medical probability. Medicine is both an art and a science, and although an individual may appear to be fit for work activity, there is no guarantee that the person will not be reinjured or suffer additional injury. If applicable, employers should follow the processes established in the Americans with Disabilities Act, Title I. The opinions on work capacity are to facilitate job placement and do not necessarily reflect an in-depth direct threat analysis. Comments on appropriateness of care are professional opinions based upon the specifics of the case and should not be generalized, nor necessarily be considered supportive or critical of, the involved providers or disciplines.

Any medical recommendations offered are provided as guidance and not as medical orders. The opinions expressed do not constitute a recommendation that specific claims or administrative action be made or enforced.

I have reviewed the excerpts and entire outline if provided and taken my own history, made additional inquiries and examinations as are necessary and appropriate to identify and determine the relevant medical issues.

I declare under penalty of perjury that the information contained in this report and its attachments is true and correct, to the best of my knowledge and belief, except as to information that I have received from others. As to that information, I declare under penalty of perjury that the information accurately describes the information provided to me, and except as noted in this report, that I believe to be true.

Certain jurisdictions may require other disclosures.

 

The next installment (part 5) in the upcoming WOEMA Newsletter will cover IME quality assurance, functional capacity evaluations, post IME and post case closure issues, fee and payment policies, testimony: defending your IME report, IME liability issues, marketing, and IME training and certification.

It’s Not Burnout, It’s a Three Alarm Fire

an editorial by Troy Ross, MD, MPH, WOEMA Newsletter Editor

 

I recently read a compelling piece, written by two physicians, who identify physician burnout as a misdiagnosis – what we call burnout is instead moral injury. I’ve run across another interesting examination of the system that we all operate within. Here a practicing surgeon calls out the “medical system” for being rigged to extract resources from everyone who takes part. He sees it as the next Big Short.

Not only are both observations on target, but I see them being connected. Now what am I, what are we, going to do with those revelations? I know what I have been doing in the past. I’ve worked around the margins and tried to avoid entanglement with the worst parts of the whole mess. I’m fortunate. In the OEM world that has been an easier task than in other areas of medicine. Hence the often advertised statistic that we have the lowest burnout rates in the medical community.

I conclude that more needs to be done – that I need to do more. I’m still deck side, enjoying the fresh breezes that remain, but the Medical Titanic is sinking.

Think globally, act locally- here’s my commitment:

1)      I will make a conscious effort to educate my patients before I treat them. I’m not talking about a simplified presentation of the pathophysiology behind the low back pain. I want them to understand their lifestyle choices that impact the need to see a doctor for back pain.

2)      Take on the pharmaceuticalization of our world. Opioids are just the tip of the iceberg. There is no “pill for every ill”. When my medical assistant brings me a list of 14 prescription medications that her 78 year old mother has accumulated after being a good patient and following her multiple doctor’s orders, I call bullshit. I helped her find a committed primary care doctor, who immediately halved the list. I now look for every opportunity to help people see past band aid drugs to look for solutions.

3)      In Don Quixote fashion I will continue to fight against the mechanization of my profession. For years I have refused to sit at a keyboard or with an electronic device, when I talk with my patients. As the business side of medicine tries to wrap everything up in a nice little EMR package I will continue to push back. My notes are my thoughts, my way of communicating to others. I don’t communicate with drops downs, or radio buttons, or ICD-9/10/ or 11 codes (and yes ICD-11 is just around the corner).

4)      Most importantly, but without a firm execution plan yet, I will work on connecting my patients to community. The individual that I see in the exam room is not the same person that lives with his family or works with his group of colleagues or recreates with his friends. Drug abuse, suicide, physician burnout – I see those problems and more as a fundamental lack of belonging to and having meaning within a community.

Would you like to help me add to the list?
