"We would have won if the ALJ wasn't so pro-employee," is a common refrain in the worker's compensation world. Undoubtedly the statement is at least partly true. However, there may be more going on than what at first meets the eye. Human beings evaluate the world using various heuristics. A heuristic is an experienced-based technique for problem-solving, learning, and discovery. Common heuristics include trial and error, rules of thumb, educated guesses, common sense, and stereotyping. Heuristics are useful because they allow us to take shortcuts when making decisions involving complicated questions. Unfortunately, heuristics often result in decisions and assumptions that are not optimal. It is critical to understand this behavioral condition when assessing why judges reach the decisions they do.One of the more common heuristics and the most vexing in the medico-legal world is the association of correlation with causation. The most frequent example involves judges and juries assigning causation because of temporal proximity. Assigning causation based on temporal proximity is a logical fallacy that, in the Latin, is called cum hoc ergo propter hoc ("with this, therefore because of this"). The logical or cognitive error is considering two independent events to be causally related because they occurred at or about the same time. In the claims arena, this frequently involves an employee who develops back pain at work without a precipitating event then concludes, with medical support, that because the back pain arose at work the work activities must have caused the back pain. Although we as humans have a natural bias toward explaining the world as a series of cause and effect relationships, imposing this bias on independent events simply because they occurred near in time erroneously establishes causation where none in fact exists.A well-known example demonstrating why the "correlation is causation" assumption is false involved claims that hormone replacement therapy (HRT) in post-menopausal women reduced heart disease. Initial reports indicated that women receiving HRT had a lower incidence of heart disease than women who did not receive HRT. However, after a large, randomized study specifically designed to test the effects of HRT in post-menopausal women, it was determined that HRT slightly increased the risk of developing heart disease in post-menopausal women. The reason for the counterintuitive result was the failure to account for confounding variables differentiating women receiving HRT versus those who did not. Put shortly, women receiving HRT were generally healthier to begin with than those women not receiving HRT. Once the confounding variables were controlled for, it was discovered that HRT had a slightly negative effect on cardiovascular disease rates. The HRT example effectively demonstrates that simply because two things are present at the same time does not mean they are related.The difficulty for claims professionals and attorneys is that they must find a way to convince judges and juries that the commonsense assumption that complaints arising during or shortly after a particular activity must be related is almost certainly false without sounding condescending. In the back pain example, most IME reports do a good job of explaining that the diagnostic imaging findings look more like the degenerative changes from aging than the changes from acute injury. However, this alone is usually insufficient to convince judges and juries that the experience of pain or disability during an activity or incident is not related to the activity or incident. Instead, the IME doctor will need to offer an analogy that judges and juries will understand. For example, we call rhinovirus infections "colds" because we used to believe that cold temperatures caused the ailment. We now recognize that "colds" are caused by viruses and that being cold has nothing to do with becoming infected. I think it is reasonable to ask independent medical examiners to use effective analogies to make it clear that medical science should trump assumptions about correlation and causation that are unreliable and probably false.
In a rare development, two researchers from Belgium discovered a new knee ligament called the anterolateral ligament ('ALL'). The researchers began looking into the possibility of an undiscovered anatomical structure in the knee because of unusual symptoms that were reported after successful ACL repairs. Specifically, "some patients with ACL-repaired knees continue to experience so-called 'pivot shift', or episodes where the knee 'gives way' during activity." Oddly enough, a French surgeon had postulated the existence of an as yet undiscovered anterior knee ligament in 1879. Over 130 years later he was proven right. The Belgian researchers published their findings in The Journal of Anatomy.In the claims setting, this discovery may impact future treatment of ACL injuries, though the discovery is so new that the extent of its impact is not known.For more information on Medical Systems go to www.MedicalSystemsUSA.com
It is common knowledge that prescription drug misuse and abuse has become a significant problem in the United States. According to the Centers for Disease Control (CDC), the costs are staggering.
http://www.cdc.gov/homeandrecreationalsafety/overdose/facts.htmlPrescription drug misuse and abuse impacts claims management in many ways. On the front end of the process, prescription misuse and abuse increases the risk that a person will be involved in an accident, whether work-related or not. In addition, persons with significant dependence problems may see the claims process as a manner of obtaining prescription medications to fuel their dependency. During the claims administration process, prescription drug misuse and abuse increases costs through extended (or unending) recovery periods and higher than normal pharmaceutical costs. In addition, drug seeking behavior often results in increased medical costs through emergency room and urgent care visits used to obtain medications. Finally, the value of prescription drug medications causes some persons who receive them to sell them as a means to generate income.What can claims professionals do to combat prescription drug misuse and abuse among claimants? The first place to start is with the primary treating physician. If it appears from your review of records that the patient is obtaining narcotic pain medication from multiple sources or has asked for an early refill on more than one occasion, communicate your concern directly to the physician. Most treating physicians are sensitive to narcotic use and will not tolerate drug-seeking behavior. In addition, you can encourage the physician to use her state’s Prescription Drug Monitoring Program, which will provide the physician with information regarding from whom and when patients are obtaining prescriptions for narcotics. Second, a medical record review can provide a good option for discontinuing payment of prescription pain-relievers and other drugs that may be being abused. Third, many states have dispute resolution mechanisms designed to address a carrier or employer’s contention that a particular treatment is not necessary to cure and relieve the effects of an injury or condition. This option provides an opportunity to challenge a recalcitrant physician’s decision to provide unwarranted prescription pain-relievers or other addictive drugs without the patient being a party to the claim. Fourth, drug and physician utilization reviews can be used to assess the likelihood that abuse is occurring when abuse is suspected but cannot otherwise be confirmed.The bottom line is that prescription drug misuse and abuse can be a significant claims cost driver. Taking a proactive approach of identifying potential abuse, working with treating physicians to curb abuse, and using independent medical or record reviews can provide an effective means of controlling the claims costs of prescription drug misuse and abuse. Beyond the claims environment, curbing prescription drug misuse and abuse also makes our society better and safer, which is a win-win for everyone.For more information on Medical Systems go to www.MedicalSystemsUSA.com
One of the most common concerns we hear regarding IME’s is that “the doctor didn’t explain why…” Frequently the issue centers around the doctor’s opinion that a particular mechanism of injury did not or could not have caused the claimant’s condition. For example, a doctor may conclude that a particular accident was not of a sufficient magnitude to have caused an acute rotator cuff tear and that the MRI findings demonstrate a wholly preexisting, degenerative process. Most claims professionals and attorneys would be happy with this opinion, but only if the opinion did not end there. We all want to know why the doctor reached her conclusion.One of the reasons doctors do not explain themselves in greater detail is that they live their entire professional lives interacting with other doctors and health professionals who do not require further explanation. If an orthopedist tells a referring internist that an accident was not of a sufficient magnitude to have caused an acute tear, the internist generally will not require additional information to understand why the doctor reached that conclusion. The orthopedist conveyed the relevant information and the internist can adjust her assessment accordingly. Unfortunately for those of us in the medico-legal world though, medical opinions do us little good unless doctors explain why they reached them.In our rotator cuff example, the doctor likely had sound reasons for her opinions. Perhaps the claimant did not complain of shoulder pain at the scene of the accident. This, any orthopedist will tell you, would be highly unusual in an acute rotator cuff tear because acute tears are painful. The tendons forming the cuff are enervated and when a complete tear occurs the nerves in and around the tendon are also torn. This causes pain, which is the body’s natural protective mechanism to keep the person from continuing to use the joint in a way that could cause further injury and impede healing.Perhaps the claimant was a seat-belted driver whose vehicle was merely sideswiped. The claimant did not report shoulder pain at the scene and did not hit her shoulder or have force transmitted to the shoulder through an outstretched arm. Most orthopedists will tell you that a minor collision that does not involve direct impact to the shoulder or indirect transmittal of force through an outstretched arm cannot physically cause a rotator cuff tear. If the shoulder is not hit or the arm is not outstretched, the rotator cuff tendon complex is essentially relaxed. In this state it cannot be torn. It is like a rubber band: if you stretch a rubber band until it is taut you can break it when additional force is applied. However, if you attempt to break a rubber band that is relaxed, nothing happens.So how can we get the doctor to explain why? The simplest way to get an explanation is to ask for it. We understand that certain questions need to be asked in a certain way, such as the Llewellyn questions in Wisconsin worker’s compensation cases (definite breakage, precipitation, aggravation, and acceleration beyond normal, or mere manifestation); however, tailoring causation questions to the mechanism of injury at issue will often get the doctor to answer why she reached her conclusions. Take the rotator cuff example above: The claimant alleges an acute rotator cuff tear arising out of a motor vehicle accident. You have reviewed the file and just don’t think the accident could have caused a rotator cuff tear because the mechanism of injury doesn’t seem right and the MRI reports suggest the tearing was of a longstanding, degenerative nature. In addition to the typical questions, you might want to ask the doctor a specific question regarding the MRI findings: “The reading radiologist on the November 2nd MRI report states that there is fraying of the supraspinatus tendon that appears to be of a degenerative nature. Please comment on whether you agree with the reading radiologist and if so what aspects of the MRI images suggest a degenerative versus an acute tear.” You might also want to ask the doctor a specific question regarding the lack of shoulder complaints immediately after the accident: “In her description of the accident and the development of her shoulder problems, the claimant does not mention shoulder pain immediately after the accident and first reports shoulder pain two weeks later. What is your opinion on whether the claimant’s report of injury and the onset of shoulder pain is consistent with suffering an acute rotator cuff tear arising out of the motor vehicle accident?”We know that there are no silver bullets in obtaining independent medical examinations. The doctors who are asked to examine claimants give an objective opinion based on the history described and the other facts available to them. Nevertheless, targeted questions can go a long way in getting the in depth explanation behind an opinion that helps bolster the IME doctor’s credibility. When preparing the cover letter to the IME doctor, consider whether there is anything unusual about the claimed injury. If the mechanism of injury doesn’t seem right, point that out to the doctor and ask her to comment specifically on the mechanism of injury and why it would be unlikely to cause the alleged injury. In many cases, you will receive a more detailed and individualized answer than you would if you only asked standardized questions.For more information on Medical Systems go to www.MedicalSystemsUSA.com
Definition:Deception is to intentionally distort the truth in order to mislead others. There are two classes of deception: concealing the truth (dissimulates or gloss over) and exhibiting false information (simulate). Malingering is intentional production of false or exaggerated symptoms motivated by external incentives, such as obtaining compensation or drugs, avoiding work or military duty, or evading criminal prosecution. Signs of Malingering:Malingering can be strongly suspected in the presence of any combination of the following occurrences:-Marked discrepancy between the claimed distress and the objective findings-Lack of cooperation during evaluation and in complying with prescribed treatment-Presence of an antisocial personality disorderMalingering often is associated with an antisocial personality disorder and a histrionic personality style. Prolonged direct observation can reveal evidence of malingering because it is difficult for the person who is malingering to maintain consistency with the false or exaggerated claims for extended periods.The person who is malingering usually lacks knowledge of the nuances of the feigned disorder. For example, someone complaining of carpal tunnel syndrome may be referred to occupational therapy, where the person who is malingering would be unable to predict the effect of true carpal tunnel syndrome on tasks in the wood shop.Prolonged interview and examination of a person suspected of a malingering disorder may induce fatigue and diminish the ability of the person who is malingering to maintain the deception. Rapid firing of questions increases the likelihood of contradictory or inconsistent responses. Asking leading questions may induce the person to endorse symptoms of a different illness. Questions about improbable symptoms may yield positive responses. However, because some of these techniques may induce similar responses in some patients with genuine psychiatric disorders, caution should be exercised in reaching a conclusion of malingering.Persons malingering psychotic disorders often exaggerate hallucinations and delusions but cannot mimic formal thought disorders. They usually cannot feign blunted affect, concrete thinking, or impaired interpersonal relatedness. They frequently assume that dense amnesia and disorientation are features of psychosis. It should be noted that these descriptions also may apply to some patients with genuine psychiatric disorders. For example, individuals with a delusional disorder can have unshakable beliefs and bizarre ideas without formal thought disorder.Physical Examination:Typically, deficits on physical examination do not follow known anatomical distributions. A patient's attitude toward the examining physician often is vague or evasive.Concerns:The time, energy, and financial commitment created by malingering individuals is an appreciable problem in health care. Whether the goal is to obtain narcotics, to obtain time off from work and/or to secure financial benefits such as disability payment, the costs to the health care delivery system have proved enormous.
