    How do you know when a patient is lying about his symptoms, condition and history? The short answer is “you don’t.” But, as this case study will demonstrate, you need to use all your senses, especially your powers of observation.

    Accusing anyone of lying is serious business, but when that person is your patient, the stakes are even higher. But what do you do when a patient really is telling a lie?

    How do you know when a patient is lying about his symptoms, condition and history? The short answer is “you don’t.” But, as this case study will demonstrate, you need to use all your senses, especially your powers of observation.

    My patient, a 33-year-old African American male, was brought from the front seat of a Greyhound bus by ambulance to the community emergency room where I was moonlighting near the end of my third year of residency.

    He reported that he had a known diagnosis of an ascending aortic dissection and was traveling from his home in Miami, Florida to see a vascular surgeon in Seattle, Washington. Aortic dissection is not a common diagnosis, occurring with an incidence of 3.5 per 100,000 per year [7]. It is frequently life-threatening, and an acute presentation requires emergent and often surgical intervention. He reported that, while on the bus, he developed chest pain, feeling both like an elephant sitting on his chest, as well as a more severe, tearing pain radiating into his back that felt like his aortic dissection. He had a past medical history of Ehlers-Danlos syndrome and chronic myelogenous leukemia, currently in remission, as well as multiple previous pneumothoraces and thromboses, both deep venous and pulmonary.

    He stated he had previously had an operation performed in Munich, Germany where his dissection had been “clipped,” but not permanently repaired, and also reported placement of an inferior vena cava filter. He claimed to have anaphylactic allergies to CT contrast, propofol, sulfa drugs, ketamine, and droperidol. He had poor peripheral veins and requested almost immediately that a central line be placed. He carried with him a well-worn copy of a transesophageal echocardiogram (TEE) report showing a possible intimal flap near his aortic valve. Initial vital signs showed a BP of 117/72 and HR of 110.

    Physical exam revealed a thin, pale male with a medial sternotomy scar, a port scar in his upper right chest, and several scars on his lateral chest consistent with previous chest tubes.

    Prior to medical school, I lived in Germany while serving in the military, so I conversationally asked him why he was there (attempting to build rapport but also curious about the consistency of his responses). He told me that he had been an ROTC student at Stuttgart and periodically driven to Munich. I commented this was a long drive, and he reported it had taken him 12 hours each time (this is a two and one half hour drive). I asked him whether he spoke German and he said that he did, but was not able to answer simple questions in German. Something did not smell right. What stood out to me was how mechanically he described his complaint and history, offering a textbook description of both angina and aortic dissection. He rattled off his list of allergies as though he’d said it a hundred times. Few patients are that fluent with their medical history.

    In addition, the description of his previous surgical intervention was quite circumspect — that a surgeon would intervene with an open-chested surgery without performing the definitive operation for his diagnosis would be a considerable deviation from the standard of care. But with his complicated past and the scars to prove it, I gave him the benefit of the doubt.

    My desire to do the right thing and care for the patient carried me forward. I was able to place an ultrasound-guided peripheral line and thereby negate his request for a central line. We administered a dose of IV esmolol and fentanyl upon his request. CT angiography is the test of choice for evaluation of aortic dissection and in the setting of a contrast allergy we will often pretreat with steroids and antihistamines.

    He utterly refused this. I offered an MR angiogram of his aorta. He replied that the metal in his chest prevented him from having an MRI. As a former MRI tech well versed in contraindications, I assured him that having an MRI would pose no risk; but he continued to refuse, saying that his previous doctors had told him he could not have one. He requested instead that we obtain a TEE, which would require sedation which, due to his allergies, would have to be performed at least in part with narcotics.

    At this point I had the opportunity to review our records, which were connected by our electronic medical record (EMR) with several associated hospitals. I discovered that he had presented to one such hospital in another state in 2011 with an identical complaint with the exception that he had been traveling from California to Kansas for his repair at that time. He had been admitted to that hospital and after an extensive workup they found no evidence of dissection. In fact, they noted that the week prior to his presentation there, he had been seen in more than ten different hospitals in the Las Vegas area.

    Turning to my technological sense, I performed a brief Internet search, which revealed several case reports of a patient that sounded identical to this patient —with the same age and history of having an exploratory sternotomy performed to evaluate this complaint. Case reports revealed he had been seen at numerous hospitals across the country from New York to California dating back to at least 2003 [8-13]. I approached the patient with this newfound information with a renewed sense of fair play and invited him to confess to his confabulations. He insisted his pain was real. In collaboration with the on-call cardiothoracic surgeon, we agreed that given his baseline low-likelihood, a CT scan without contrast would be sufficient to rule out significant aortic pathology. This was performed and was, predictably, negative for aortic dissection. It did show a venacaval filter and some small surgical clips in his anterior mediastinum, presumably from his exploratory surgery. I again confronted the patient, this time with a rational sense — with concrete data. At this point he requested to leave and I discharged him.

    So, what was really going on here?

    Malingering

    Malingering is characterized by an intentional deception, including both invention and exaggeration, concerning a physical or psychgological condition with the goal of obtaining some external reward, e.g., not having to work, food or shelter, avoiding arrest, etc [14].

    One study suggests that the rate of malingering in the emergency department may be as high as 13%, with the belief that in recent years, this has only increased [15,16].

    Another study found that among patients with chronic pain, the rate of malingering was between 20 and 50% [17]. By federal law, patients must be screened for an emergency medical condition, so regardless of the so called “red flags,” some sort of an evaluation must be completed. Regardless, malingering must always be a diagnosis of exclusion, and the excluding process costs time and resources.

    Munchausen or factitious disorder

    Munchausen syndrome, also known as factitious disorder imposed on self (as classified by DSM V), involves more dramatic and convincing presentations by often well-informed patients without an obvious secondary gain. The goal of patients with factitious disorder is often simply to be the center of attention: to be actively cared-for, to play the role of sick patient. They accomplish this by employing deception to exaggerate, fabricate, simulate, or induce their symtpoms [14]. They are often well-informed about their feigned conditions, understandably so as they have typically had numerous diagnostic evaluation and therapeutic interventions for them, and have been so convincing that they often carry scars as a result of these investigations [18].

    These patients will often take medications such as insulin or immunosuppressants, or introduce extraneous blood to emesis or urine samples in order to alter laboratory testing and prolong the ruse. They are often confrontational and almost invariably leave against medical advice after health care workers become less compliant to their requests for pain medicine, intervention, or treatment in the face of largely negative evaluations.

    Emergency departments are particularly susceptible to these patients as the disorders they mimic often require immediate intervention. An emergency physician must always consider factitious disorder to be a diagnosis of exclusion, so even when one suspects that something is irregular, he or she must nevertheless continue the evaluation and treatment until such devastating diagnoses are excluded. Munchausen by proxy, or factitious disorder imposed on another, involves creation or confabulation of disease in another person, usually a child, with the goal of assuming a central role as the patient’s caregiver.

    For a listing of diagnostic criteria for factitious disorders, see figure 1:

    Somatization or Somatic Symptom Disorder

    Somatization disorder is the presence of physical symptoms that, after complete diagnostic evaluation, have not been found to have a physical or organic cause. DSM V has abandoned this diagnosis with the following statement: “It is not appropriate to give an individual a mental disorder diagnosis solely because a medical cause cannot be demonstrated.” They have replaced it with the more specific diagnosis of somatic symptom disorder. Unlike its predecessor, this new diagnosis includes patients whose symptoms can be explained medically as well as those whose cannot.

    Patients’ reaction to symptoms is excessive and disproportionate, with high levels of anxiety and excessive energy spent on addressing these symptoms. The most common complaints include pain, gastrointestinal complaints, cardiovascular complaints such as palpitations or shortness of breath, or neurologic complaints such as dizziness, weakness, or paresthesias [19,20]. Somatization disorder has previously been associated with risk factors such as mental illness, sexual abuse, low socio-economic status, minority status, and female sex [19,21].

    These patients are often ED recidivists and frequent various specialists who have not been able to give them a diagnosis or present them with a satisfactory treatment plan. The best approach is to have such patients establish care with one primary physician who can track their symptoms over time and monitor for changes that might herald organic disease, while avoiding the problem of multiple providers initiating multiple interventions – which might cause iatrogenic disease. Compliance with this approach has been problematic as this population favors the convenience of emergency departments and often does not make or keep appointments [19].

    Factitious disorders, malingering, and somatization or somatic symptom disorder are a problem for the emergency department. These patients are often skilled in deception and well informed about current medical practices and the hesitancy providers may feel to distrust a potentially serious presentation. The [appropriate]concern in medicine – not to miss a serious diagnosis – has allowed patients like the one highlighted above to abuse the healthcare system for years. While few are likely as adept as he, the standard practice of giving the benefit of the doubt allows an impossibly unknown number of others to similarly take advantage of the system in smaller ways.

    There have been numerous methods proposed in the past to detect the less veracious patient. These methods are both poorly defined and poorly sensitive.

    It should be noted, one study found that several of these behaviors – including lost or stolen prescriptions, pain greater than 10 out of 10, or requesting of a specific route – were present in only a minority of patients who were eventually referred for chemical dependency [24]. Electronic communication systems and databases, including the electronic health record (EHR), are advancements that should improve our ability to detect and avoid redundant management of such patients. These may take many forms including health information exchange between participating hospitals and healthcare facilities (such as the system used to find records about this patient), and state prescription drug monitoring systems. Evidence gleaned from review of such systems can provide a justification to avoid costly and invasive testing.

    Various techniques have been employed by ED physicians including direct confrontation and request for identification — as some patients give falsified names or birthdays. These techniques often result in the patient opting to leave the ED without further assessment or treatment. Circulation of aliases and descriptions are problematic due to patient privacy issues, but as many of the more complex perpetrators tend to have well-studied and consistent histories, disseminated information and awareness of these patients without specific data constituting protected health information may be sufficient to raise the level of suspicion for a particular complaint or implausible presentation.

    In the psychiatric literature, there are numerous studies designed to define criteria to identify prevaricators. These require complex neurocognitive testing such as the Minnesota Multiphasic Personality Inventory, the Symptom Validity Test, and the Fake Bad Scale that are not reasonable options in the ED, particularly for complaints with potentially devastating outcomes such as dissection [25,26]. One author presents a five-criteria system with a relatively low sensitivity and high specificity that, due to the requirement for neurocognitive testing, is only partially applicable for the ED. His criteria include:

    • Presence of external incentive

    • Physical findings, defined as perception of poor effort, non-organic cluster of symptoms, discrepancies in story, and changed behavior based upon whether the patient believes he or she is being observed or not

    • Compelling inconsistency, e.g. some- one who says he cannot walk and then does

    • Lack of other diagnosis that fits the symptoms better [25]

    Those who have experience working in an emergency room develop a sense for the gestalt of a drug-seeking patient, an unconscious recognition that may or may not be dependent upon some of the above described criteria. One study comparing the ED provider’s impression to a state prescription drug monitoring program found that such a gestalt had a sensitivity of 63.2% and a specificity of 72.7% for identifying drug-seeking behavior [27]. This suggests that ED physicians likely have a good sense of who is and is not present in the ED for secondary gain. This intuition or awareness of subtle irregularities should cue the practitioner into looking for some of the other more classic characteristics of nefarious intent. This appears to be the most accurate method of detection yet identified barring logistically prohibitive testing.

    Those who choose to abuse healthcare resources for their own secondary gain harm not only themselves, but those from whom the resources of time, tests, and therapies are being diverted. To simply acquiesce because it is easier – and it always is – is an impediment to good patient care. Indulging such patients, thinking that our actions have little consequence on the broader picture in the life of either the individual or the healthcare environment at large – adds to the problem. The available studies on rates suggest that EDs are already taxed by demands of increasing patient volume and corporate compliance. Through the use of electronic resources and increasing awareness, we may avoid unnecessary and wasteful care and deliver better service to those who legitimately require it.
