    The IME Defined

    How does an IME report differs from a Medical Report?

    Who request IMEs?

    In what context are IMEs done?

    8

  • 1.0 IME Definition

    An examination performed by an independent health care professional who has no relationships with the examinee or requesting party, for the purpose of providing the requesting party with an outside impartial medical opinion about the examinee.

    9

  • “The medico-legal report in civil personal injury matters is to help a judge or jury decide issues of liability, causation and the appropriate amount of compensation for an injured person.

    AND/OR … to determine the entitlement of the patient or claimant to certain benefits including income replacement benefits, and medical and rehabilitation expenses. “

    10 The Medico-Legal Report 2008

    The Medico-Legal Society of Toronto

  • 11 Roles and Responsibilities

    1. Provide all documents that are relevant to the issues to be addressed in the report.

    2. Explain the overriding duty of the physician to assist the court on the matters within their expertise in an independent manner.

    3. Explain the purpose of the report, the manner in which it will be disseminated and the use to which it may be put at trial.

    4. Advise the physician of his or her obligation to attend the proceedings to give testimony.

    5. Provide complete instructions outlining the questions to be answered and the standard of proof applicable to these questions.

    1. Expertise to offer the opinion on the relevant issues.

    2. Obligation to attend trial and give testimony as may be required.

    3. SABS - it is considered an "unfair and deceptive act or practice" for an assessment to be conducted by a person whom the insurer or its representative knows or ought to know is not reasonably qualified to conduct the assessment based on training or experience.

    4. The physician must provide complete, clear and reasoned answers to the questions to be answered.

  • Additional Information 12

  • How does an IME report differs from a Medical Report?

    Require a specialized inquiry

    Will generally be widely distributed

    Must be easily read by lay people (non-medical)

    May or may not lead to the well-being of the examinee

    Should assist with the claim adjudication, management or disposition of the case

  • Other Names for IME

    Independent Medical Opinion (IMO)

    Independent (Discipline) Examination

    Impartial Medical Examination

    Insurer’s Examination (IE)

    14

  • Purpose

    The IME is a tool of dispute resolution used when there is an element of a medical nature.

    The dispute may be narrow and specific, involving questions of diagnosis, treatment, attribution, apportionment, negligence, prognosis, damages etc..

    The dispute may be wide-ranging, involving long-range care costs or querying fraud.

    5.9 Example

    37

  • The Clinician as a Fiduciary

    Clinician and “patient” relationship entails the highest

    conceivable degree of trust and fidelity.

    The clinician will act solely and entirely in the “patient’s best interest”.

    The clinician will permit no competing interests including his/her own interest to interfere with or compete with the primacy of the “patient’s interest”.

    The examinee or claimant is NOT a patient. The Fiduciary role of the IME clinician is not well defined.

    38

  • Seeking Patient’s Consent

    The clinician must take steps to make sure that the patient has the information reasonably necessary to make an informed choice.

    That the patient should be given such information and should provide his/her consent on that knowledgeable basis has come to be known as “informed consent”

    39

  • Autonomy

    Autonomy means the patient’s moral right to make decisions about his/her medical care.

    Respect for the person requires that clinicians favour a patient’s control of their own lives.

    The patient’s consent must be sought for all examinations or procedures.

    40

  • Consent may be Expressed or Implied

    Expressed consent is a specific and active affirmation by the patient that the clinician has permission to undertake the procedure proposed.

    Consents given verbally are usually reduced to writing and signed by the patient or a person entitled by law to substitute for the patient.

    The clinician asks for permission to provide a medical service and provides information to the patient about the risks and benefits.

    41

  • Consent is the activity that took place

    When the patient has understood the information and received answers to any questions, the patient provides permission and consents to the treatment.

    The patient signs the document.

    It is the activity that took place which constitutes the consent, the paper merely records it.

    42

  • Implied Consent Rules of Civil Procedures

    In some circumstances, the patient’s conduct may be taken to reasonably imply that consent took place.

    The patient who comes to a clinician’s office, readily and willingly presents him/herself to the physician, gives his/her history and agrees to be examined will be taken to have consented to routine examination without having expressed that consent verbally or in writing.

    43

  • Scope of Consent

    Consent to treatment extends only to what was

    reasonably in the minds of the clinician and the patient when the consent was given

    Consent given for one procedure/process does not necessarily cover another or different procedure.

    Use of vague language in consents purporting to authorize any action the clinician considers advisable is legally risky

    44

  • Substituted Consent

    Minors, those who have not achieved the age of majority, may not consent and thus consent for their treatment must be given by their parent or legal guardian.

    Generally exceptions are provided to the rule requiring parental consent.

    In most jurisdictions, parental consent is not required where the treatment proposed responds to a genuine emergency.

    45

  • Substituted Consent

    In the case of adults suffering from diminished mental capacity, the intervention of others authorized by law to act as substitute decision-makers is required.

    It is wise to consider the issue in respect of all psychiatric patients and where anything in the history or examination indicates the possibility of incapacity.

    The substitute decision-maker will have all the rights to reasonable information that the patient would have enjoyed had they been competent

    46

  • CPSO Informed Consent

    Physicians must obtain the patient’s or examinee’s

    consent for disclosing personal health information to

    the third party and for conducting a medical

    examination. The College strongly advises physicians to document that consent has been obtained.

    47

  • CPSO Consent Disclosure of Information

    The consent process will vary depending on the circumstances of each case, however, at minimum, physicians should ensure the following points are conveyed:

    Patients or examinees can withdraw consent at any time, however, this will prevent the physician from completing and submitting the report;

    Patients or examinees are entitled to place limits on the information that physicians can disclose in a report, however, such limitations may prevent physicians from proceeding with the reports process; and

    Physicians have obligations to be truthful and accurate when detailing information in the report, and when forming a professional opinion about the patient’s or the examinee’s condition or functional abilities.

    CPSO Third Party Reports Policy #2-12 - November 2012

    48

  • CPSO Consent Medical Information

    Through the consent process, physicians should ensure patients

    and examinees understand that the examination is being

    conducted to prepare the report and should outline what the

    examination will entail.

    This includes an indication of what areas of the body will be

    examined, what functional capabilities the physician will be

    testing, and what types of questions the physician may have to

    ask.

    49

  • CPSO Presence of Observers & Audio/Video Recording

    The College is aware that parties may wish to have an

    observer present during an examination, or may request

    that the examination be recorded by audio or video

    equipment.

    If physicians are conducting an examination for the

    purposes of a legal proceeding and one or more parties

    wish to have an observer present, they should discuss the

    matter with the lawyer involved, as specific rules may apply.

    For example, for court-ordered examinations, the Rules of

    Civil Procedure indicate that observers shall not be present during examinations unless the court orders otherwise.

    50

  • CPSO Presence of Observers & Audio/Video Recording

    If the matter is not related to a legal proceeding, the College advises that although physicians are not obligated to conduct an examination in the presence of an observer or to record an examination, they are permitted to do so if they wish.

    In these instances, any arrangements with respect to observers or recording must be mutually agreeable to the parties involved. Should the parties disagree over whether the examination will be recorded, or will be conducted in the presence of an observer, the College recommends that the examination be postponed until these matters can be discussed and a resolution reached.

    53

  • Civil Claim for Damages Intro

    Purpose

    The purpose of a civil claim arising out of personal injury suffered as a result of an accident, clinical negligence or at work is to achieve financial compensation also known as “damages”.

    Legal Basis of a Civil Claim (Statement of Claim)

    In order to succeed in a personal injury claim, it is necessary to prove:

    1. That the tortfeasor (defendant) is in breach of a duty of care owed to the claimant (plaintiff).

    2. That the injury, loss or damages (more than minimal) has been caused as a result of the negligence or breach of duty or a term of contract.

    3. The nature and extent of the injury, loss or damages sustained

    54

  • Civil Claim for Damages Concepts

    Negligence

    Negligence is the failure to take reasonable care to prevent foreseeable

    injury to a person for whom there was a legal duty owed.

    In the most frequently encountered personal injury claims such as MVAs and Slip and falls, the issue of breach of duty (liability) is not a matter for expert medical evidence. However, breach of duty is a matter central to the role of medical experts in clinical negligence claims.

    Psychologists or psychiatrists may be asked to address the “reasonable foreseeability” arising from exposure of the claimant to particular situations or stressors. (Mustapha v. Culligan of Canada Ltd., [2008] 2 S.C.R. 114, 2008 SCC 27)

    55

  • Civil Claim for Damages Concepts

    Negligence, Civil Responsibility and Standard of Care

    In jurisdictions subject to common law, four elements must be established or proven for any legal action based upon a claim for negligence to be successful:

    1. There must be a duty of care owed to the patient.

    2. There must be a breach of that duty of care.

    3. The patient must have suffered some harm or injury.

    4. The harm or injury must be directly related or caused by the breach of the duty of care.

    CMPA Medical-legal Handbook for Physicians in Canada V. Sept 2016

    56

  • Civil Claim for Damages Concepts

    Causation

    In all claims, the plaintiff must establish that the injury, loss and damage were caused by the negligence or breach of duty of the defendant.

    Standard and Burden of Proof

    In a civil case, the plaintiff must prove his case to the civil standard of proof, “on the balance of probabilities (probable or >50%).

    Types of Damages

    General Damages (Non Economic Loss or Non-Pecuniary)

    (pain, suffering, disfigurement, loss of enjoyment of life / amenities & FLA)

    Special Damages (future care cost, housekeeping, home maintenance)

    o Economic or Pecuniary Loss (to date and in the future & employment disadvantages etc. )

    Punitive Damages (rare)

    57

  • Medicolegal Challenge

    Claimants do not always express their arguments clearly, often leaving some of the premises unstated, on the assumption that the evaluator will know what they have in mind or will not notice their reliance on faulty assumptions.

    Evaluators do not systematically identify the claimant’s assertions or arguments, apparently not realizing that failing to closely examine the argument will have a strong negative impact on their ability to assess the claim at hand.

    58

  • An argument, by definition, consists of a conclusion which is drawn from a premise.

    This is an argument that uses deductive logic.

    59

    Health care is universal for Canadians. [Premise]

    You are a Canadian.

    Therefore, you have universal health care. [Conclusion]

    5.1 Standard Argument Structure

  • Necessary and Sufficient Conditions

    In order to evaluate an argument effectively you must be clear about the conclusion; that is, you must know what needs to be proven.

    In order to make a diagnosis, a medical professional needs to know what diagnostic criteria must be present.

    60

  • Exacerbation vs Aggravation

    Exacerbation

    Temporary increase in the symptomology of a pre-existing condition (flare-up).

    Aggravation

    Long-standing effect due to an event, resulting in a worsening, hastening or deterioration of a pre-existing condition.

    61

  • 5.2 Health Claim Statement

    62

    The Health Claim Statement (HCS) is a technical tool that assists in outlining the major elements of the claim in dispute.

    While the HCS itself has yet to be widely adopted, the majority of its components can be found in most IME reports in a less organized or complete fashion.

    Hybrid between “Chief Complaints” in the clinical setting and the “Statement of Claim”. The Examination for Discovery can also be helpful to clarify the HCS.

  • 5.2 HCS Process

    63

    The HCS is formulated at the outset of the interview. It will guide in the development of the specialized inquiry needed to collect and analyze the data necessary to draw well-justified inferences.

    The HCS obtained from the claimant is reconstructed into a causal argument format showing its temporal and logical structure within a tort medicolegal and scientific context.

    Through this ordered approach, the evaluator can more accurately examine the validity and soundness of the argument and more accurately assess each element (premise) of the claim.

  • 5.3 HCS Standard Form

    64

    1. The plaintiff’s pre-existing health status did not cause or materially contribute to the accident itself (premise).

    2. The plaintiff’s pre-existing health status is non-contributory to the personal injury, loss or damages (premise).

    3. The defendant’s wrongful act contributed to or caused the accident (liability premise).

    4. The accident materially contributed to or caused the plaintiff’s personal injury, loss or damages (proximal cause premise).

    5. The plaintiff has made a reasonable attempt to minimize the personal injury or loss (premise).

    6. There are no other causes for the accident and/or personal injury loss or damages (rebuttal premise).

    7. But for the wrongful act of the defendant (accident), the plaintiff’s personal injury would not have occurred (conclusion).

  • 5.4 HCS Tort Principles

    65

    1. Status Quo Ante: This premise deals with the cause in fact of the accident and whether the plaintiff’s pre-existing health status, such as driving under the influence, caused or contributed to the accident itself.

    2. Status Quo Ante, Thin Skull and Crumbling Skull: This premise has to do with the proximal cause and whether the plaintiff’s pre-existing health status has caused or contributed in some way to the personal injury.

    3. Liability Issue and Cause in Fact: This legal premise addresses the key liability issue or cause in fact.

    4. Proximal Cause: This premise has to do with the proximal cause and damages or whether the accident has materially contributed to or caused the plaintiff’s personal injury or loss. This is a central issue for the evaluator to address during causal analysis.

    If there was a pre-existing health condition, the evaluator must determine if the accident led to an exacerbation (flare-up), aggravation (new injury or loss) or acceleration of the pre-existing health condition, or if the effects of the accident are unrelated.

  • 5.4 HCS Tort Principles

    66

    5. Mitigation of Loss Doctrine: This premise deals with the expectation that the plaintiff has taken reasonable steps to minimize his loss. In other words, the evaluator assesses the plaintiff’s participation in the medical and rehabilitation (medical and vocational) process.

    6. Novus Actus Interveniens: There have been no intervening events (compensable or not) that would cause or contribute to the plaintiff’s personal injury. Causal apportionment becomes a consideration if two or more compensable events contribute to the plaintiff’s personal injury.

    7. But For: “But for” comes from the Latin expression “Sublata causa, tollitur effectus”, meaning “remove the cause, and the effect will disappear”, or “but for this cause, that effect would not have resulted”. The “But for” singular causal argument conclusion needs to be analyzed on the basis of the previous premises.

    Mr. Jones reported no prior history of health problems, or prior health or disability insurance claims.

    He stated that at the time of the August 8, 2016 MVA, he was in excellent physical and psycho-emotional health, and had no activity limitations or difficulties fulfilling all his social roles. Mr. Jones also denied any prior physical, mental or behavioural impairment [(1) Status Quo Ante, (2) Status Quo Ante, Thin Skull and Crumbling Skull].

    Mr. Jones reported that Mr. Smith failed to stop for a red light at the time of the August 8, 2016 MVA. Mr. Jones stated that, but for Mr. Smith’s wrongful act, the August 8, 2016 MVA would not have occurred [(1) Status Quo Ante, (3) Liability Issue and Cause in Fact, (7) But For].

    Mr. Jones indicated that solely as a result of the August 8, 2016 MVA, he experienced the following [(4) Proximal Cause]:

    Left tibial plateau fracture with subsequent open reduction/internal fixation, external fixation and plates [(5) Mitigation of Loss Doctrine], resulting in left knee pain

    Left tibia/fibula open fracture with subsequent open reduction/internal fixation, Ilizarov procedure and muscle flap and skin flap surgeries [(5) Mitigation of Loss Doctrine], resulting in left lower leg and shin pain

    Right femur fracture with subsequent retrograde nailing and rod insertion [(5) Mitigation of Loss Doctrine] resulting in calcium scar build-up and right mid-thigh pain

    Mr. Jones reported that he has been seeing Mr. Bob Williams, physiotherapist, since September 2016 and has been fully compliant with all treatment [(5) Mitigation of Loss Doctrine].

    Mr. Jones denied any intervening accident, trauma, injury or disabling illness since the August 8, 2016 MVA. Mr. Jones indicated that the August 8, 2016 MVA was the only possible cause of his current health state, including his impairments, activity and social participation limitations [(6) Rebuttal Premise – Novus Actus Interveniens].

  • HCS Example

    69

    Mr. Jones indicated that solely as a result of the August 8, 2016 MVA, he experienced the following [(4) Proximal Cause]:

    Left tibial plateau fracture with subsequent open reduction/internal fixation, external fixation and plates [(5) Mitigation of Loss Doctrine], resulting in left knee pain

    Left tibia/fibula open fracture with subsequent open reduction/internal fixation, Ilizarov procedure and muscle flap and skin flap surgeries [(5) Mitigation of Loss Doctrine], resulting in left lower leg and shin pain

    Right femur fracture with subsequent retrograde nailing and rod insertion [(5) Mitigation of Loss Doctrine] resulting in calcium scar build-up and right mid-thigh pain

    As a result of his MVA-related lower extremity impairment, Mr. Jones reported that he can no longer weight bear for more than 5 minutes or participate in housekeeping, home maintenance, social activities or work.

  • HCS Example

    70

    Mr. Jones reported that he has been seeing Mr. Bob Williams, physiotherapist, since September 2016 and has been fully compliant with all treatment [(5) Mitigation of Loss Doctrine].

    Mr. Jones denied any intervening accident, trauma, injury or disabling illness since the August 2016 MVA. [(6) Rebuttal Premise – Novus Actus Interveniens].

    Mr. Jones reported that his injuries, impairments, activity and social participation limitations are all and only attributable to the August 8, 2016 MVA.

    Bias can occur in any of the parties involved in the IME process, including requesting parties, lawyers, judges, etc., and can also be present in regulations and laws.

    Even with the most careful and diligent data collection, bias as a part of the IME process may cause an evaluator to draw distorted, inaccurate, and even false conclusions.

    Biases, generally speaking, are errors of flawed or selective data. Bias occurs when an evaluator, either unconsciously or deliberately, and with either the best or the worst of intentions, alters, overlooks, omits, promotes, or gives preference to certain data in order to support a pre-determined conclusion.

    The evaluator should be aware of how bias in its many forms may influence the IME, and what, if anything, can be done about it.

    103

  • What is Evidence?

    Factual determinations are based on the examination and evaluation of the information or “evidence” that has been presented.

    Evidence, therefore, is the data for factual decision making.

    (Paciocco 1996)

    104

  • Why have Rules of Evidence?

    The rules perform a variety of functions, controlling what information the trier of fact can receive, how that information is to be presented, as well as the use that can be made of it.

    Admissibility of evidence is a question of law.

    105

  • Sources of Evidence Law in Ontario

    Canada Evidence Act (Federal Courts)

    Ontario Evidence Act (Provincial Courts)

    Ontario Statutory Powers Procedure Act allows tribunals to admit as evidence and act upon any oral testimony or any document or other thing relevant to the subject matter of the proceedings, whether admissible as evidence or not in a court of law.

    106

  • The Basic Rule of Evidence

    Information can be admitted as evidence where it is relevant to a material issue in the case.

    Evidence that is not directed at a matter in issue in the case is “immaterial”.

    (Paciocco 1996)

    107

  • Daubert Decision & Expert Testimony

    US Federal Rules of Evidence Rule 702

    “If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise.”

    108

  • Daubert Decision & Expert Testimony

    The Daubert case addressed specifically the admissibility of “scientific” testimony which could be considered relevant and reliable. (How to deal with Junk Science!)

    The Court has identified five “tests” to assist the trier of fact to determine the admissibility of scientific knowledge.

    109

  • Daubert’s Five “Tests”

    1) A key question to be answered is, ordinarily, whether the theory or technique can be and has been tested;

    2) A pertinent consideration is whether the theory or technique has been subjected to peer review and publication, although the fact of publication, of lack thereof, in a peer reviewed journal is not a dispositive consideration;

    3) The Court should ordinarily consider the known or potential rate of error of a particular scientific technique;

    110

  • Daubert’s Five “Tests”

    4) The assessment of reliability permits, but does not require, explicit identification of relevant scientific community and an express determination of a particular degree of acceptance of the theory or technique within that community, as

    (a) widespread acceptance can be an important factor in ruling particular evidence admissible, and

    (b) a known technique that has been able to attract only minimal support within the scientific community may properly be viewed with skepticism;

    111

  • Daubert’s Five “Tests”

    5) The inquiry is a flexible one, and the focus must be solely on principles and methodology, not on the conclusions that such principles and methodology generate.

    Argument Analysis Basics

    Necessary and sufficient conditions

    Common Logical Fallacies

    Legal / Medical Claim Statement

    115

  • An argument, by definition, consists of a conclusion which is

    drawn from a premise.

    This is an argument that uses deductive logic.

    Health care is universal for Canadians. [Premise] You are a Canadian. Therefore, you have universal health care. [Conclusion]

    What is an Argument? 116

  • All psychiatrists are medical doctors. [Premise]

    Dr. Smith is a psychiatrist.

    Dr. Smith is a medical doctor. [Conclusion]

    Deductive vs Inductive Logic

    Deductive Arguments

    Deductive logic works from first principles. The conclusion draws out implications contained in the premise.

    The conclusion draws out implications contained in the

    premise.

    Forms of Logic 117

  • Forms of Logic

    Mr. Jones has headaches every morning. [Premise]

    It is now morning.

    Mr. Jones will have a headache. [Conclusion]

    Inductive arguments are projections that aremade on the basis of past experience.

    118

  • Valid or Invalid Arguments

    All claimants give an accurate medical history. [Premise]

    Ms. Smith is a claimant.

    Therefore, Ms. Smith gives an accurate medical history. [Conclusion]

    This is a valid argument although it has a false premise.

    Arguments are also classified as either being valid or invalid. Validity, however, says nothing about the truth of an argument.

    119

  • Sound or Unsound Arguments

    If the premise of an argument is true, and the argument is valid, then it is sound.

    These are the types of arguments we should rely on in medicolegal analyses and writing.

    An argument with either a false premise, or that is not valid is unsound.

    120

  • Argument Analysis Basics

    In general, in analyzing arguments, consider the following:

    1. Identify the conclusion

    2. Assess the truth of the premise

    3. Decide on the validity of the conclusion

    Again, a valid argument with a true premise is a sound one!

    121

  • Common Logical Fallacies

    Critical thinking also looks at common flaws in arguments, which are also called fallacies.

    Let us now look at five common types of fallacies:

    • Strawman

    • Ad hominem

    • Red herring

    • Appeal to ignorance

    • Appeal to tradition

    122

  • Strawman Fallacy The strawman fallacy is committed when someone attacks a

    position that is different (usually a weaker reconstruction) from, but similar to the original argument. By refuting the different version, the original argument is refuted. For example:

    Many people think that the health care system does not need more money. If people would just stop worrying about every little ache and pain and putting so much stress on the health care system with trivial problems, we wouldn’t need more money. People need to get busy and get a life. There isn’t enough money to provide every diagnostic test for every patient.

    123

  • Ad Hominem Fallacy

    I’m fed up with Dr. Quack’s medical theories about fibromyalgia. I used to think that he had some valid ideas, but he’s just another crackpot who hasn’t done his homework. He talks a lot about patient care, but he’s just in it for the money.

    In an ad hominem fallacy, the source of the argument is attacked, rather than the argument itself.

    124

  • Red Herring Fallacy

    I’m tired of those people who say that we need to put more money into emergency rooms. The real problem is, what are they going to do about the waiting lists for cancer treatment?

    When one responds to a criticism of a position held by launching a counter-attack by raising a completely different issue, one commits the red herring fallacy. It is an attempt to take you away, so to speak, from the original argument.

    125

  • The Appeal to Ignorance Fallacy

    I believe that post-traumatic multiple sclerosis exists and I read current medical journals. No papers that I read disprove it. Therefore, it must be true.

    Often in difficult medical diagnoses, the absence of any contrary evidence is used to support the original diagnoses. This may or may not be legitimate. Why?

    This fallacy assumes in some mysterious way that the absence of evidence that something is false supports the claim that it is true.

    126

  • Fallacy of Denying the Antecedent If p then q. Not- p therefore, not-q This type of argument is somewhat difficult to

    determine from its legitimate form. Denying the

    antecedent takes the following form:

    Why is this faulty?

    If Dr. X. knew that he had insulted Dr. Y. he would apologise. Dr. X. did not know that he had insulted Dr. Y. Therefore he did not apologise.

    127

  • Appeal to tradition/ history

    This fallacy assumes that because a view or position has been held for many years it is correct.

    Since this treatment has been the traditional approach to depression, it must be right.

  • Introduction to Causation

    Causation or the determination of a causal link is the most difficult medicolegal challenge.

    It is usually poorly dealt with by the experts due to the lack of method.

    The evaluation of a possible causal link and the determination of causation require a specialized inquiry.

    Determination of medicolegal causation is the critical issue in liability.

    131

  • Definitions

    Causation is the relation of cause to effect.

    To be legally sufficient, the physician’s opinion as to causation must be based on a “reasonable degree of medical certainty”.

    Attribution is the process by which a cause(s) is / are assigned to an effect.

  • Bradford Hill

    In 1965, Sir Austin Bradford Hill made a major contribution to the newly founded Section of Occupation-al Medicine of the Society of Epidemiology with his classic paper:

    The Environment and Disease: Association or Causation?

    Dr. Hill set forth 9 guidelines that should be considered in establishing the relationship between environmental exposure and effect.

  • 8.2 (b)(iii)(A)Causal Fallacies - Confusing Necessary and Sufficient Conditions In order to evaluate an argument effectively you must be

    clear about the conclusion; that is, you must know what needs to be proven.

    In order to make a diagnosis, a medical professional needs to know what diagnostic criteria must be present.

    153

  • For example, in order to diagnose mental retardation three conditions must be present:

    1. Significantly subaverage intellectual functioning (an IQ of approximately 70 or below).

    2. Concurrent deficits or impairments in present adaptive functioning in at least two areas.

    3. Onset before age 18 years.

    154

  • In some instances there may be diagnostic criteria that are sufficient on their own.

    In the case of a diagnosis of WAD Grade I, three criteria are listed: complaint of neck pain or stiffness or tenderness.

    Each one of these criteria by itself is a sufficient condition to diagnose a WAD Grade I.

  • If we finish this file by Friday, we’ll go to the beach.

    If the Oilers hadn’t traded Wayne Gretzky, they would have continued to be a Stanley Cup winning team.

    In daily life we make statements using the concept of necessary and sufficient conditions:

    In these statements we are making claims about sufficient conditions: finishing the file is a sufficient condition for going to the beach; Wayne Gretzky playing for the Oilers is a sufficient condition for winning the Stanley Cup.

    156

  • We would go to Toronto only if someone else drove us there.

    We would buy mutual funds only if they were ethical mutual funds.

    We also make statements about necessary conditions:

    In these cases we are claiming that someone driving us is a necessary condition for us to go to Toronto and that a mutual fund being ethical is a necessary condition for purchase.

    157

  • Sometimes you want to affirm a particularly strong relationship.

    If the only way you can develop a disease is by being bitten by a certain insect, and if the bite of this insect always causes this disease, then the bite of the insect is a necessary and sufficient condition for the disease.

  • Evidence-Based Analysis 160

  • What is Evidence-Based Medicine?

    EBM is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients.2

    EBM originated at McMaster (Ontario) in 1992 by a group led by Dr. Gordon Guyatt.

    2 Sackett DL, BMJ 1996; 312: 71-2

  • EBM: Four Realizations3

    Daily need for valid information about diagnosis, prognosis, therapy and prevention (up to 5 times per in-patient and twice for every 3 out-patients).

    Inadequacy of traditional sources for this information because they are out-of-date (textbooks), frequently wrong (experts), ineffective (didactic continuing medical education) or too overwhelming in their volume and too variable in their validity for practical clinical use (medical journals).

    The disparity between our diagnostic skills and clinical judgement, which increase with experience, and our up-to-date knowledge and clinical performance, which decline.

    Our inability to afford more than a few seconds per patient for finding and assimilating this evidence, or to set aside more than half an hour per week for general reading and study.

    3 Evidence-based Medicine: How to Practice and Teach EBM Straus et al. 3rd Ed. Churchill

    Livingstone, 2005 p.2

  • What Makes EBM Possible Now

    The creation of systematic reviews and concise summaries of the effects of health care (e.g. Cochrane Collaboration).

    The creation of evidence-based journals of secondary publication (that publish the 2% of clinical articles that are both valid and of immediate clinical use).

    Information systems that bring readily useable and valid information in a matter of seconds. You no longer need to be an academic to “appear” smart.

  • Logic and Clinical Judgment

    Science in medicine is about producing evidence.

    Logic and critical thinking is about rational uses of evidence.

    Complete and methodologically impeccable evidence about a health problem is not enough to make valid and valuable choices.

    If the interpretation of the evidence is not logically sound or used uncritically, the patient may be harmed. The patient may equally harmed by logically flawless use of poor or poorly evaluated evidence.

    Evidence-based practice: logic and critical thinking in medicine.

    M. Jenicek and DL Hichcock AMA press 2005

  • Scientific vs. Legal Evidence

    While clinicians and lawyers may use the same word “evidence”, their understanding and application of evidence are quite different, leaving the patient/claimant with medical needs caught in the middle.

    In contrast to EBM, the search for truth in law is an adversarial one. The theory is that if both sides make the best case for their position, the truth will emerge from the evidence that is presented.

    In order to win, lawyers recruit “experts” that will make the best case for their position. Eminence-based and opinion-based evidence prevails. In this forum, “Credibility” , “believability” and rhetoric win over weighing scientific facts, validity and relevancy.

  • Scientific vs. Legal Evidence

    In health care, evidence helps to determine the likelihood that an event in the future will be beneficial to the patient.

    In law, evidence is used to determine the causation of an event in the past to determine who was accountable for it and who was harmed by it.

  • 9.2 Word Reference and Meaning

    Words

    “The smallest units of meaningful, natural language are words. Technicalities aside, it is important to see that we normally distinguish two aspects of meaningful words: what sort of things they are about (what they refer to), and what their cognitive significance is (what they mean).” (Savellos and Galvin)

    173

  • 9.2 Word Reference and Meaning

    Reference

    “Reference is a relation that [holds] between expressions and [the things] speakers use expressions to talk about. When I assert ‘George W. Bush is Republican’, I use the proper name ‘George W. Bush’ to refer to a particular individual …” (http://plato.Stanford.edu/entries/references/)

    174

  • 9.2 Word Reference and Meaning

    Meaning: Semantics vs. Pragmatics

    “When a diplomat says yes, he means ‘perhaps’; “When he says perhaps, he means ‘no’; “When he says no, he is not a diplomat.”

    175

  • 9.2 Word Reference and Meaning

    Meaning: Semantics vs. Pragmatics

    “… more is involved in what one means than the standard, conventional meaning of the words one uses. … each [word] has a perfectly identifiable meaning, known by every speaker of English …. However, as those [previous] lines illustrate, it is possible for different speakers in different circumstances to mean different things using … words.” (http://plato.stanford.edu/entries/pragmatics/)

    176

  • 9.2 Word Reference and Meaning EXAMPLE

    Impairment

    “the impairment”

    Refers to a precise limitation in a particular body function, such as 10° reduction in flexibility

    177

  • 9.2 Word Reference and Meaning EXAMPLE

    Impairment

    “an impairment”

    Meaning (semantic): “problems in body function or structure such as a significant deviation or loss.” (http://www.who.int/classifications/icf/site/intros/ICF-Eng-Intro.pdf)

    178

  • 9.2 Word Reference and Meaning EXAMPLE

    Impairment

    Meaning (pragmatic): depends on who says it, when they say it, and what exactly they say!

    179

  • 9.3 Medicalization and Misuse of Lawyerisms

    EXAMPLE

    Material contribution vs causation

    Tort definition: permanent serious impairment of an important physical, mental or psychological function.

    The need to go back to a medical and scientific framework

    180

  • 9.4 Ambiguity and Vagueness

    Ambiguity: A word is ambiguously used in a given context when that context does not make it clear which of the several meanings of the word is intended.

    EXAMPLE: “Mr. Smith sustained what looks like a right tibial fracture.”

    Has a right tibial fracture been observed? Or does Mr. Smith’s injury just appear to be one?

    181

  • 9.4 Ambiguity and Vagueness

    Vagueness: A word is vague when there is a “gray area” of applicability of the word, i.e., there are borderline cases in which it is not whether or not the word can be correctly applied.

    EXAMPLE: “Mr. Jones experiences severe pain.”

    How much pain is “severe”? What kind of pain is “severe”?

    Terms like significant, substantial, complete, severe should only be used if the grading is from an objective, generally-accepted scale and set of definitions

    191

  • 9.7 Rhetorical Power of Words EXAMPLE

    More persuasive:

    “Unfortunately, Dr. Smith did not indicate in his report that the Desbiens decision does not respect the intent of Chapter 14, page 301 of the Guides with respect to the lack of percentages used in the 4th edition. Moreover, it is my opinion that whether the specifics of the Desbiens decision are applicable to Mr. Jones is a legal matter best addressed by the trier of fact. I am thus perplexed as to the basis of the legal opinion offered by Dr. Smith.”
