Posttraumatic stress disorder (PTSD) has increasingly become a part of American culture since its introduction in the American Psychiatric Association’s third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980.¹ Since then, a proliferation of material about this disorder—both academic and popular—has been generated, yet much confusion persists surrounding the definition of the disorder, its prevalence, and its management. This review addresses the essential elements for diagnosis and treatment of PTSD.

Diagnosis: A closer look at the criteria

Criteria for the diagnosis of PTSD have evolved since 1980, with changes in the definition of trauma and the addition of symptoms and symptom groups.² Table 1³ summarizes the current DSM-5 criteria for PTSD.

Trauma exposure. An essential first step in the diagnosis of PTSD is to determine whether the individual has experienced exposure to trauma. This concept is defined in Criterion A (trauma exposure).³ PTSD is nonconformist among the psychiatric diagnoses in that it requires a specific external event as part of its definition. Misapplication of the trauma exposure criterion by many clinicians and researchers has led to misdiagnosis and erroneously high prevalence estimates of PTSD.^4,5

A traumatic event is one that represents a threat to life or limb, specifically defined as “actual or threatened death, serious injury, or sexual violence.”³ DSM-5 does not allow for just any stressful event to be considered trauma. For example, no matter how distressing, failing an important test at school or being served with divorce proceedings do not represent a requisite trauma⁶ because these examples do not entail a threat to life or limb.

DSM-5 PTSD Criterion A also requires a qualifying exposure to the traumatic event. There are 4 types of qualifying exposures:

• direct experience of immediate serious physical danger
• eyewitness of trauma to others
• indirect exposure via violent or accidental trauma experienced by a close family member or close friend
• repeated or extreme exposure to aversive details of trauma, such as first responders collecting human remains or law enforcement officers being repeatedly exposed to horrific details of child abuse.³

Witnessed trauma must be in person; thus, viewing trauma in media reports would not constitute a qualifying exposure. Indirect trauma exposure can occur through learning of the experience of a qualifying trauma exposure by a close family member or personal friend.

It is critical to differentiate exposure to trauma (an objective construct) from the subjective distress that may be associated with it. If trauma has not occurred or a qualifying exposure is not established, no amount of distress associated with it can establish the experience as meeting Criterion A for PTSD. This does not mean that nonqualifying experiences of stressful events are not distressing; in fact, such experiences can result in substantial psychological angst. Conversely, exposure to trauma is not tantamount to a diagnosis of PTSD, as most trauma exposures do not result in PTSD.^7,8

Continue to: Symptom groups

Symptom groups. DSM-5 symptom criteria for PTSD include 4 symptom groups, Criteria B to E, respectively:

• intrusion
• avoidance
• negative cognitions and mood (numbing)
• hyperarousal/reactivity.

A specific number of symptoms must be present in all 4 of the symptom groups to fulfill diagnostic criteria. Importantly, these symptoms must be linked temporally and conceptually to the traumatic exposure to qualify as PTSD symptoms. Specifically, the symptoms must be new or substantially worsened after the event. For example, continuing sleep disturbance in someone who has had lifetime difficulty sleeping would not count as a trauma-related symptom. Most symptom checklists do not properly assess diagnostic criteria for PTSD because they do not anchor the symptoms in an exposure to a traumatic event; diagnosis requires an interview to fully assess all the diagnostic criteria. Finally, the symptoms must have been present for >1 month for the diagnosis, and the symptoms must have resulted in clinically significant distress or functional impairment to qualify.

The Algorithm provides a practical way to systematically assess all DSM-5 criteria for PTSD to arrive at a diagnosis. The clinician begins by determining whether a traumatic event has occurred and whether the individual had a qualifying exposure to it. If not, PTSD cannot be diagnosed. Alternative diagnoses to consider for new disorders that arise in the context of trauma among patients who are not exposed to trauma include major depressive disorder, adjustment disorder, and bereavement, as well as acute stress disorder (which is not validated but has potential utility as a billable diagnosis).

Some PTSD symptoms may seem quite similar to symptoms of depressive disorders and anxiety disorders. PTSD can be differentiated from these other disorders by linking the symptoms temporally and contextually to a qualifying exposure to a traumatic event. More often than not, PTSD presents with comorbid psychiatric disorders, especially depressive disorders, anxiety disorders, and/or substance use disorders.⁵ Epidemiologic research on PTSD has shown consistently that pre-existing psychopathology is a strong predictor of PTSD following trauma exposure, as well as of psychiatric comorbidity. These comorbid conditions may be as important as the PTSD in choosing a treatment, and they should be treated concurrently with PTSD.^6,13

Continue to: Treatment: Medication, psychotherapy, or both

Treatment: Medication, psychotherapy, or both

Both pharmacotherapy and psychotherapy—as monotherapy or in combination—are beneficial for treatment of PTSD. Research has not conclusively shown either treatment modality to be superior, because adequate head-to-head trials have not been conducted.⁴ Therefore, the choice of initial treatment is based on individual circumstances, such as patient preference for medication and/or psychotherapy, or the availability of therapists trained in evidence-based PTSD psychotherapy. Pharmacotherapeutic approaches are considered especially beneficial for depressive- and anxiety-like symptoms of PTSD, and trauma-focused psychotherapies are presumed to address the neuropathology of conditioned fear and anxiety responses involved in PTSD.¹⁴ Table 2^14-25 provides a list of published treatment guidelines and reviews to help clinicians seeking further detail beyond that provided in this article.

A well-established barrier to effective pharmacotherapy of PTSD is medication nonadherence.¹³ Two common underlying sources of nonadherence are inconsistency with the patient’s treatment preference and intolerable adverse effects. Because SSRIs/SNRIs require 8 to 12 weeks of adequate dosing for symptom relief,¹³ medication adherence is vital. Explaining to patients that it takes many weeks of consistent dosing for clinical effects and reassuring them that the antidepressant agents used to treat PTSD are not habit-forming may help improve adherence.⁴

Psychotherapy. Prolonged exposure therapy and cognitive processing therapy—both trauma-focused therapies—have the best empirical evidence for efficacy for PTSD.^4,14,26 Some patients are too anxious or avoidant to participate in trauma-focused psychotherapy and may benefit from a course of antidepressant treatment before initiating psychotherapy to reduce hyperarousal and avoidance symptoms enough to allow them to tolerate therapy that incorporates trauma memories.⁶ However, current PTSD treatment guidelines no longer recommend stabilization with medication or preparatory therapy as a routine prerequisite to trauma-focused psychotherapy.⁴

Continue to: Eye movement desensitization and reprocessing (EMDR) therapy...

Eye movement desensitization and reprocessing (EMDR) therapy has emerged as a popular trauma-focused therapy with documented effectiveness. During EMDR, the patient attends to emotionally disturbing material in brief sequential doses (which varies with individual patients) while simultaneously focusing on an external stimulus, typically therapist-directed lateral eye movements. Critics of EMDR point out that the theoretical concepts and therapeutic maneuvers (eg, finger movements to guide eye gaze) in EMDR are not consistent with current understanding of the neurobiological processes involved in PTSD. Further, studies testing separate components of the therapy have not established independent effectiveness of the therapeutic maneuvers beyond the therapeutic effects of the psychotherapy components of the procedure.⁴

Other psychotherapies might also be beneficial, but not enough research has been conducted to provide evidence for their effectiveness.⁴ Non-trauma–focused psychotherapies used for PTSD include supportive therapy, motivational interviewing, relaxation, and mindfulness. Because these therapies have less evidence of effectiveness, they are now widely considered second-line options. Psychological first aid is not a treatment for PTSD, but rather a nontreatment intervention for distress that is widely used by first responders and crisis counselors to provide compassion, support, and stabilization for people exposed to trauma, whether or not they have developed PTSD. Psychological first aid is supported by expert consensus, but it has not been studied enough to demonstrate how helpful it is as a treatment.⁶

Comorbidities require careful consideration

PTSD in the presence of other psychiatric disorders may require a unique and specialized approach to pharmacotherapy and psychotherapy. For instance, for a patient who has a comorbid substance use disorder, acute substance withdrawal can exacerbate PTSD symptoms. Sertraline is considered a medication of choice for these patients,¹³ and having a substance abuse specialist on the treatment team is desirable.^4,13 A patient with comorbid traumatic brain injury (TBI) may have reduced tolerance to medications, and may require an individually-tailored and elongated titration strategy. Additionally, stimulants sometimes used to improve cognition for patients with comorbid TBI can exacerbate symptoms of hyperarousal, and these patients may need stabilization before beginning PTSD treatment. Antidepressant treatment for PTSD among patients with comorbid bipolar disorder has the potential to induce mania. Psychiatrists must consider these issues when formulating treatment plans for patients with PTSD and specific psychiatric comorbidities.^4,6

PTSD symptoms can be chronic, sometimes lasting many years or even decades.²⁷ In a longitudinal study of 716 survivors of 10 different disasters, 62% of those diagnosed with PTSD were still symptomatic 1 to 3 years after the disaster, demonstrating the enduring nature of PTSD symptoms.¹² Similarly, a follow-up study of survivors of the Oklahoma City bombing found 58% of those with PTSD and 39% of those without PTSD were still reporting posttraumatic stress symptoms 7 years after the incident.²⁸ Remarkably, these same individuals reported substantially improved functioning at work, with family and personal activities, and social interactions,²⁸ and long-term employment disability specifically related to PTSD is highly unusual.²⁹ Even individuals who continued to report active posttraumatic stress symptoms experienced a return of functioning equivalent to levels in individuals with no PTSD.²⁸ These data suggest that treating psychiatrists and other mental health clinicians can be optimistic that functioning can improve remarkably over the long term, even if posttraumatic stress symptoms persist.

Bottom Line

A thorough understanding of the criteria for posttraumatic stress disorder (PTSD) is necessary for accurate diagnosis and treatment. Evidence-based treatment options for adults with PTSD include certain antidepressants and trauma-focused psychotherapies.

CASE Anxiety in the ICU

Mr. B, age 42, an African American man, is admitted to the inpatient medical unit for surgical treatment of peritoneal carcinomatosis with pelvic exenteration. He has a history of metastatic rectal cancer, chronic pain, and hypertension, but no psychiatric history. Mr. B’s postsurgical hospital stay is complicated by treatment-resistant tachycardia and hypertension, and he requires a lengthy stay in the ICU. In the ICU, Mr. B reports having visual hallucinations where he sees an individual placing a drug in his IV line. Additionally, he reports severe anxiety related to this experience. His anxiety and visual hallucinations are treated with coadministration of IV lorazepam, diphenhydramine, and haloperidol. These medications resolve the hallucinations, but his anxiety worsens and he becomes restless. He receives additional doses of IV haloperidol administered in 5 mg increments and reaching a cumulative 12-hour dose of 50 mg. Mr. B continues to report anxiety, so the psychiatry consultation-liaison (C-L) service is called.

[polldaddy:9970907]

The authors’ observations

Determining the cause of Mr. B’s anxiety is challenging because of his prolonged medical course, comorbidities, and exposure to multiple pharmacologic agents. The consulting psychiatric team should consider potential medical, psychiatric, and drug-related etiologies.

From a medical perspective, in a post-surgical patient treated in the ICU, the consulting practitioner must pay particular attention to delirium. ICU delirium is common—one report indicated that it occurs in 32.3% of ICU patients¹—and frequently confused with psychiatric morbidity.² Identifying delirium as the cause of impairment is important because delirium has potentially modifiable underlying etiologies. Symptomatically, delirium presents as impairment and fluctuation in attention, awareness, and at least one other cognitive domain, with a clear indication that the impairment occurred over a short period of time and represents a departure from baseline.³ In Mr. B’s case, these symptoms have not been excluded and should be considered by the C-L psychiatrists.

In addition to delirium, the C-L team must consider psychiatric comorbidity. Mr. B has no psychiatric history and a sudden first occurrence of hallucinations; therefore, it is unlikely that he has developed a primary psychotic disorder. Because he reported his symptoms had been present only for several days, he would not meet criteria for schizophrenia, which according to DSM-5 criteria require at least 1 month of ≥2 symptoms (including delusions, hallucinations, disorganized speech, disorganized behavior, or negative symptoms) and 6 months of declining function.³ However, although it is improbable, the C-L team must consider a primary psychotic illness, particularly given the potential devastating consequence of being misdiagnosed and mismanaged for an alternative illness. Unlike psychotic disorders, anxiety disorders are significantly more prevalent in the U.S. general population than primary psychotic disorders.⁴ Furthermore, the prevalence of anxiety disorders increases in the ICU setting; one study found that up to 61% of ICU patients setting experience “anxiety features.”⁵ Therefore, anxiety disorders and stress disorders should be considered in ICU patients who exhibit psychiatric symptoms.

Clinicians also should consider medication-induced adverse effects. In the ICU, patients are frequently managed on multiple medications, which increase their risk of developing adverse effects and adverse reactions.⁶ One potential consequence of polypharmacy is delirium, which remains a relevant potential diagnosis for Mr. B.⁷ Alternative consequences vary by medication and their respective pharmacodynamics. We take into consideration Mr. B’s exposure to high doses of the high-potency antipsychotic agent, haloperidol. Exposure to haloperidol can result in extrapyramidal symptoms, including akathisia,^8,9,10 and the rare, but potentially fatal, NMS.¹¹ These reactions can often be distinguished by taking a thorough history and a physical evaluation. In the case of akathisia, the clinician should look for medication exposure, titration, or taper. Most commonly, akathisia occurs secondary to antipsychotic exposure,¹² followed by the onset of a combination of subjective symptoms, such as restlessness, anxiety, and irritability, and an objective symptom of increased motor activity.³ NMS, on the other hand, is distinguished by symptoms that include hyperthermia (>38ºC), diaphoresis, severe rigidity, urinary incontinence, vital instability, alterations in mental health status, and elevations in creatine kinase greater than 4-fold the upper limit, usually in the setting of treatment with antipsychotics.³ Nearly all cases of NMS occur within the first 30 days of antipsychotic exposure.³ While, overtly, NMS may appear to be less subtle than akathisia, clinicians should still be weary to rule out this admittedly rare, though potentially lethal diagnosis, especially in an ICU patient, where the diagnosis can be muddied by medical comorbidities that may mask the syndrome.

EVALUATION Focus on akathisia

On interview by the C-L team, Mr. B is visibly restless, moving all 4 extremities. He reports increased anxiety and irritability over the past 2 to 3 days. Mr. B states that he is aware of his increased motor movements and can briefly suppress them. However, after several seconds, he again begins spontaneously fidgeting, moving all 4 extremities and shifting from side to side in bed, saying, “I just feel anxious.” He denies having visual hallucinations, and says that the previous hallucinations had spontaneously presented and remitted after surgery. He denies the use of psychotropics for mental illness, prior similar symptoms to this presentation, a family history of mental illness, recent illicit substance use, or excessive alcohol use prior to presentation. This history is corroborated by collateral information from his brother, who was present in the ICU. On physical examination, Mr. B is afebrile and his vital signs are within normal limits. He does not have muscular rigidity or neck dystonia. His laboratory values, including complete blood count, electrolytes, liver function tests, and creatine phosphokinase, are within normal limits.

His medication administration record includes 46 standing agents, 16 “as-needed” agents, and 8 infusions. Several of the standing agents had psychotropic properties; however, the most salient were several opioids, ketamine, midazolam, lorazepam, dexamethasone, haloperidol, and olanzapine.

[polldaddy:9970908]

The authors’ observations

We determined that the most likely diagnosis for Mr. B’s symptoms was medication-induced akathisia secondary to haloperidol. Akathisia, coined by Haskovec in 1901,^12,13 is from Greek, meaning an “inability to sit.”¹² DSM-5 describes 2 forms of akathisia: medication-induced acute akathisia, and tardive akathisia.³ In the literature, others have described additional classifications, including chronic akathisia, withdrawal akathisia, and pseudoakathisia (Table 1^3,14-17). In Mr. B’s case, given his sudden development of symptoms and their direct chronologic relationship to antipsychotic treatment, and his combined subjective and objective symptoms, we believed that Mr. B’s symptoms were consistent with medication-induced acute akathisia (MIA). The identification and treatment of this clinical entity is important for several reasons, including reducing patient morbidity and maximizing patient comfort. Additionally, because akathisia has been associated with poor medication adherence, increased agitation/aggression, increased suicidality, and the eventual development of tardive dyskinesia,¹⁸ it is a relevant prognostic consideration when deciding to treat a patient with antipsychotics.

Pathophysiologically, we have yet to fully shed light on the exact underpinnings of akathisia. Much of our present knowledge stems from patient response to pharmacologic agents. While dopamine blockade has been linked to akathisia, the exact mechanism is not completely understood. Previous theories linking nigrostriatal pathways have been expanded to include mesocortical and mesolimbic considerations.^12,17,18 Similarly surmised from medication effects, the transmitters y-aminobutyric acid, serotonin/5-hydroxytryptamine (5-HT), norepine­phrine, and acetylcholine also have been linked to this syndrome, though as of yet, exact gross pathophysiologic mechanisms have not been fully elucidated.¹² More recently, Stahl and Loonen¹⁹ described a novel mechanism by which they link the shell of the nucleus accumbens to akathisia. In their report, they indicate that the potential reduction in dopaminergic activity, secondary to antipsychotic administration, can result in compensatory noradrenergic activation of the locus coeruleus.¹⁹ The increased noradrenergic activity results in the downstream activation of the shell of the nucleus accumbens.¹⁹ The activation of the nucleus accumbens shell, which has been linked to unconditioned feeding and fear behavior, can then result in a cascade of effects that would phenotypically present as the syndrome we recognize to be akathisia.¹⁹

Numerous etiologies have been linked to MIA. Of these, high-potency antipsychotics are believed to remain the greatest risk factor for akathisia,¹⁸ although atypical antipsychotics, selective serotonin reuptake inhibitors, and serotonin-norepinephrine reuptake inhibitors, have been linked to the disorder.^18,19

Continue to: Regarding antipsychotics...

Regarding antipsychotics, risk factors for akathisia include drug potency, dose, and rapidity of titration.²⁰ All of these factors were relevant in our patient’s case. Risk across antipsychotic classes is not well understood; few head-to-head studies have comparing antipsychotics. However, general estimates suggest a 15% to 40% prevalence in patients exposed to typical antipsychotics, as compared with 0% to 12% exposed to atypical antipsychotics.⁸ The literature-reported difference in risk, as well as our patient’s comparative difference in exposure to large doses of haloperidol (50 mg) as compared with 1 dose of olanzapine (5 mg), led us to believe his akathisia developed primarily due to his exposure to haloperidol. Conclusively linking his symptoms to haloperidol alone, however, is not possible, and we did consider that olanzapine may in fact have had some effect in worsening Mr. B’s akathisia.

[polldaddy:9970909]

The authors’ observations

While there are reports on the efficacy of various agents in the treatment of akathisia, the most commonly evaluated agents are propranolol, anticholinergics, and benzodiazepines.^{17, 21}

Propranolol is a nonselective beta-adrenergic blocker with numerous indications.¹⁷ Despite a 2004 Cochrane Review indicating that there is no evidence in support of central acting beta-blockers for treating akathisia,²² propranolol is not yet recognized as an appropriate treatment.¹⁷ The reason for this discrepancy is likely due to the Cochrane Review’s restrictive inclusion criteria, which prevented the analysis of much of the literature.²² In fact, several reports cite evidence for the treatment efficacy of propranolol¹⁷ and, to date, some reports continue to advocate for its use as a first-line agent in the treatment of akathisia. Admittedly, besides the Cochrane Review,²² other reports have found propranolol to be ineffective for treating akathisia,²³ although these tend to be limited by their population size and generalizability.

As with propranolol, a 2006 Cochrane Review found “no reliable evidence to support or refute” using anticholinergic agents in the treatment of akathisia.²⁴ We suspect that the review’s findings were likely secondary to its strict inclusion criteria.²⁴ In fact, several reports support using anticholinergic agents for treating akathisia.²⁵ Here we focus on benztropine and diphenhydramine.

Two reviews—Blaisdell²⁶ (1994) and Poyurovsky²⁷ (2010)—suggest modest benefits from benztropine, primarily in patients with comorbid Parkinson’s disease. Despite these benefits, head-to-head trials seem to either point to the superiority of propranolol or to no difference between these agents for treating akathisia.^28,29 In a review, we only found 1 trial demonstrating benztropine’s superiority over propranolol,²³ but this trial was constrained by its small population (6 patients). Therefore, the data suggest that, when indicated, clinicians should lean towards using propranolol for treating akathisia.

Continue to: Diphenhydramine, a first-generation antihistamine...

Diphenhydramine, a first-generation antihistamine with antimuscarinic properties, has been studied for its efficacy in treating metoclopramide-induced akathisia in the emergency setting.³⁰ There are several reports on the efficacy of this agent, including a large randomized study involving 281 patients that found it effective for preventing metoclopramide-induced akathisia.³⁰ Another head-to-head trial reported the benefit of the diphenhydramine vs midazolam.³¹ Both agents were efficacious for treating akathisia; however, midazolam had a more rapid onset. Despite these positive reports, double-blind trials have found diphenhydramine to be ineffective,¹⁷ which suggests propranolol should be the first-line agent, assuming it is not contraindicated.

Benzodiazepines have also been found to be efficacious for treating akathisia. A 1999 Cochrane Review included 2 randomized controlled trials that assessed the efficacy of clonazepam vs placebo for treating akathisia.³² It found evidence of benefit for clonazepam, but questioned the generalizability of these studies.³² This review did not include several other reports that suggest benefits of other benzodiazepines for treating akathisia. Other than clonazepam, reports suggest benefit for diazepam, lorazepam, and midazolam for treating akathisia.¹⁷ Despite this evidence and the findings from this Cochrane Review, the literature does not appear to point to clear dominance of these agents over propranolol. Given the safety concerns when prescribing benzodiazepines, it would be prudent to utilize propranolol as a first-line agent for treating akathisia.

Finally, other reports have cited treatment efficacy linked to serotonin 2A receptor (5-HT2A) antagonists (mianserin, mirtazapine, and trazodone), clonidine, gabapentin, amantadine, and other agents.¹⁷ If treatment with propranolol is ineffective or contraindicated, clinicians should utilize their clinical judgement in deciding on the use of one agent over another.

OUTCOME Complete resolution

Haloperidol is discontinued and diphenhydramine, 50 mg IV, is administered. (Diphenhydramine was used instead of propranolol due to immediacy of availability.) Most of Mr. B’s signs and symptoms resolve on a repeat interview 3 hours later. He receives another dose of diphenhydramine, 25 mg IV, for persistent mild irritability. By Day 2 of follow-up, his symptoms completely resolve as measured on the Barnes Akathisia Scale³³ (Table 2).

Bottom Line

Akathisia is an elusive adverse effect of antipsychotics and can be misdiagnosed as anxiety. Close consideration should be given to potential medical, psychiatric, and drug-related etiologies in patients who have a prolonged medical course, comorbidities, and exposure to multiple pharmacologic agents.

CASE Anxiety in the ICU

Mr. B, age 42, an African American man, is admitted to the inpatient medical unit for surgical treatment of peritoneal carcinomatosis with pelvic exenteration. He has a history of metastatic rectal cancer, chronic pain, and hypertension, but no psychiatric history. Mr. B’s postsurgical hospital stay is complicated by treatment-resistant tachycardia and hypertension, and he requires a lengthy stay in the ICU. In the ICU, Mr. B reports having visual hallucinations where he sees an individual placing a drug in his IV line. Additionally, he reports severe anxiety related to this experience. His anxiety and visual hallucinations are treated with coadministration of IV lorazepam, diphenhydramine, and haloperidol. These medications resolve the hallucinations, but his anxiety worsens and he becomes restless. He receives additional doses of IV haloperidol administered in 5 mg increments and reaching a cumulative 12-hour dose of 50 mg. Mr. B continues to report anxiety, so the psychiatry consultation-liaison (C-L) service is called.

[polldaddy:9970907]

The authors’ observations

Determining the cause of Mr. B’s anxiety is challenging because of his prolonged medical course, comorbidities, and exposure to multiple pharmacologic agents. The consulting psychiatric team should consider potential medical, psychiatric, and drug-related etiologies.

From a medical perspective, in a post-surgical patient treated in the ICU, the consulting practitioner must pay particular attention to delirium. ICU delirium is common—one report indicated that it occurs in 32.3% of ICU patients¹—and frequently confused with psychiatric morbidity.² Identifying delirium as the cause of impairment is important because delirium has potentially modifiable underlying etiologies. Symptomatically, delirium presents as impairment and fluctuation in attention, awareness, and at least one other cognitive domain, with a clear indication that the impairment occurred over a short period of time and represents a departure from baseline.³ In Mr. B’s case, these symptoms have not been excluded and should be considered by the C-L psychiatrists.

In addition to delirium, the C-L team must consider psychiatric comorbidity. Mr. B has no psychiatric history and a sudden first occurrence of hallucinations; therefore, it is unlikely that he has developed a primary psychotic disorder. Because he reported his symptoms had been present only for several days, he would not meet criteria for schizophrenia, which according to DSM-5 criteria require at least 1 month of ≥2 symptoms (including delusions, hallucinations, disorganized speech, disorganized behavior, or negative symptoms) and 6 months of declining function.³ However, although it is improbable, the C-L team must consider a primary psychotic illness, particularly given the potential devastating consequence of being misdiagnosed and mismanaged for an alternative illness. Unlike psychotic disorders, anxiety disorders are significantly more prevalent in the U.S. general population than primary psychotic disorders.⁴ Furthermore, the prevalence of anxiety disorders increases in the ICU setting; one study found that up to 61% of ICU patients setting experience “anxiety features.”⁵ Therefore, anxiety disorders and stress disorders should be considered in ICU patients who exhibit psychiatric symptoms.

Clinicians also should consider medication-induced adverse effects. In the ICU, patients are frequently managed on multiple medications, which increase their risk of developing adverse effects and adverse reactions.⁶ One potential consequence of polypharmacy is delirium, which remains a relevant potential diagnosis for Mr. B.⁷ Alternative consequences vary by medication and their respective pharmacodynamics. We take into consideration Mr. B’s exposure to high doses of the high-potency antipsychotic agent, haloperidol.

Akathisia, coined by Haskovec in 1901,^12,13 is from Greek, meaning an “inability to sit.”¹² DSM-5 describes 2 forms of akathisia: medication-induced acute akathisia, and tardive akathisia.³ In the literature, others have described additional classifications, including chronic akathisia, withdrawal akathisia, and pseudoakathisia (Table 1^3,14-17). In Mr. B’s case, given his sudden development of symptoms and their direct chronologic relationship to antipsychotic treatment, and his combined subjective and objective symptoms, we believed that Mr. B’s symptoms were consistent with medication-induced acute akathisia (MIA). The identification and treatment of this clinical entity is important for several reasons, including reducing patient morbidity and maximizing patient comfort. Additionally, because akathisia has been associated with poor medication adherence, increased agitation/aggression, increased suicidality, and the eventual development of tardive dyskinesia,¹⁸ it is a relevant prognostic consideration when deciding to treat a patient with antipsychotics.

Pathophysiologically, we have yet to fully shed light on the exact underpinnings of akathisia. Much of our present knowledge stems from patient response to pharmacologic agents. While dopamine blockade has been linked to akathisia, the exact mechanism is not completely understood. Previous theories linking nigrostriatal pathways have been expanded to include mesocortical and mesolimbic considerations.^12,17,18 Similarly surmised from medication effects, the transmitters y-aminobutyric acid, serotonin/5-hydroxytryptamine (5-HT), norepine­phrine, and acetylcholine also have been linked to this syndrome, though as of yet, exact gross pathophysiologic mechanisms have not been fully elucidated.¹² More recently, Stahl and Loonen¹⁹ described a novel mechanism by which they link the shell of the nucleus accumbens to akathisia. In their report, they indicate that the potential reduction in dopaminergic activity, secondary to antipsychotic administration, can result in compensatory noradrenergic activation of the locus coeruleus.¹⁹ The increased noradrenergic activity results in the downstream activation of the shell of the nucleus accumbens.¹⁹ The activation of the nucleus accumbens shell, which has been linked to unconditioned feeding and fear behavior, can then result in a cascade of effects that would phenotypically present as the syndrome we recognize to be akathisia.¹⁹

Numerous etiologies have been linked to MIA. Of these, high-potency antipsychotics are believed to remain the greatest risk factor for akathisia,¹⁸ although atypical antipsychotics, selective serotonin reuptake inhibitors, and serotonin-norepinephrine reuptake inhibitors, have been linked to the disorder.^18,19

Continue to: Regarding antipsychotics...

Regarding antipsychotics, risk factors for akathisia include drug potency, dose, and rapidity of titration.²⁰ All of these factors were relevant in our patient’s case. Risk across antipsychotic classes is not well understood; few head-to-head studies have comparing antipsychotics. However, general estimates suggest a 15% to 40% prevalence in patients exposed to typical antipsychotics, as compared with 0% to 12% exposed to atypical antipsychotics.⁸ The literature-reported difference in risk, as well as our patient’s comparative difference in exposure to large doses of haloperidol (50 mg) as compared with 1 dose of olanzapine (5 mg), led us to believe his akathisia developed primarily due to his exposure to haloperidol. Conclusively linking his symptoms to haloperidol alone, however, is not possible, and we did consider that olanzapine may in fact have had some effect in worsening Mr. B’s akathisia.

[polldaddy:9970909]

The authors’ observations

While there are reports on the efficacy of various agents in the treatment of akathisia, the most commonly evaluated agents are propranolol, anticholinergics, and benzodiazepines.^{17, 21}

Propranolol is a nonselective beta-adrenergic blocker with numerous indications.¹⁷ Despite a 2004 Cochrane Review indicating that there is no evidence in support of central acting beta-blockers for treating akathisia,²² propranolol is not yet recognized as an appropriate treatment.¹⁷ The reason for this discrepancy is likely due to the Cochrane Review’s restrictive inclusion criteria, which prevented the analysis of much of the literature.²² In fact, several reports cite evidence for the treatment efficacy of propranolol¹⁷ and, to date, some reports continue to advocate for its use as a first-line agent in the treatment of akathisia. Admittedly, besides the Cochrane Review,²² other reports have found propranolol to be ineffective for treating akathisia,²³ although these tend to be limited by their population size and generalizability.

As with propranolol, a 2006 Cochrane Review found “no reliable evidence to support or refute” using anticholinergic agents in the treatment of akathisia.²⁴ We suspect that the review’s findings were likely secondary to its strict inclusion criteria.²⁴ In fact, several reports support using anticholinergic agents for treating akathisia.²⁵ Here we focus on benztropine and diphenhydramine.

Two reviews—Blaisdell²⁶ (1994) and Poyurovsky²⁷ (2010)—suggest modest benefits from benztropine, primarily in patients with comorbid Parkinson’s disease. Despite these benefits, head-to-head trials seem to either point to the superiority of propranolol or to no difference between these agents for treating akathisia.^28,29 In a review, we only found 1 trial demonstrating benztropine’s superiority over propranolol,²³ but this trial was constrained by its small population (6 patients). Therefore, the data suggest that, when indicated, clinicians should lean towards using propranolol for treating akathisia.

Continue to: Diphenhydramine, a first-generation antihistamine...

Diphenhydramine, a first-generation antihistamine with antimuscarinic properties, has been studied for its efficacy in treating metoclopramide-induced akathisia in the emergency setting.³⁰ There are several reports on the efficacy of this agent, including a large randomized study involving 281 patients that found it effective for preventing metoclopramide-induced akathisia.³⁰ Another head-to-head trial reported the benefit of the diphenhydramine vs midazolam.³¹ Both agents were efficacious for treating akathisia; however, midazolam had a more rapid onset. Despite these positive reports, double-blind trials have found diphenhydramine to be ineffective,¹⁷ which suggests propranolol should be the first-line agent, assuming it is not contraindicated.

Benzodiazepines have also been found to be efficacious for treating akathisia. A 1999 Cochrane Review included 2 randomized controlled trials that assessed the efficacy of clonazepam vs placebo for treating akathisia.³² It found evidence of benefit for clonazepam, but questioned the generalizability of these studies.³² This review did not include several other reports that suggest benefits of other benzodiazepines for treating akathisia. Other than clonazepam, reports suggest benefit for diazepam, lorazepam, and midazolam for treating akathisia.¹⁷ Despite this evidence and the findings from this Cochrane Review, the literature does not appear to point to clear dominance of these agents over propranolol. Given the safety concerns when prescribing benzodiazepines, it would be prudent to utilize propranolol as a first-line agent for treating akathisia.

Finally, other reports have cited treatment efficacy linked to serotonin 2A receptor (5-HT2A) antagonists (mianserin, mirtazapine, and trazodone), clonidine, gabapentin, amantadine, and other agents.¹⁷ If treatment with propranolol is ineffective or contraindicated, clinicians should utilize their clinical judgement in deciding on the use of one agent over another.

OUTCOME Complete resolution

Haloperidol is discontinued and diphenhydramine, 50 mg IV, is administered. (Diphenhydramine was used instead of propranolol due to immediacy of availability.) Most of Mr. B’s signs and symptoms resolve on a repeat interview 3 hours later. He receives another dose of diphenhydramine, 25 mg IV, for persistent mild irritability. By Day 2 of follow-up, his symptoms completely resolve as measured on the Barnes Akathisia Scale³³ (Table 2). 

Continue to: Bottom Line

 

 

Bottom Line

Akathisia is an elusive adverse effect of antipsychotics and can be misdiagnosed as anxiety. Close consideration should be given to potential medical, psychiatric, and drug-related etiologies in patients who have a prolonged medical course, comorbidities, and exposure to multiple pharmacologic agents.

Editor’s note : Career Choices features a psychiatry resident/fellow interviewing a psychiatrist about why he or she has chosen a specific career path. The goal is to inform trainees about the various psychiatric career options, and to give them a feel for the pros and cons of the various paths.

In this Career Choices, Cornel Stanciu, MD, talked with Mufida Wadhwania, MD. Dr. Wadhwania is an adult psychiatrist practicing in an urban/public setting in metro Atlanta, Georgia, at DeKalb Community Service Board. She manages a variety of uninsured and underinsured patients in an outpatient setting.

Dr. Stanciu: What attracted you to practice community mental health in an urban-public setting?

Dr. Wadhwania: A high portion of the population here has no health insurance, and hence there is a great need in the community. The psychopathology severity is high, so one can see a wide range of disorders. One can also build on the skill to pull together resources, such as linking patients to community resources and patient assistance programs, finding food banks, and finding ways to secure stable housing. There is continuity of care, and when a staff member leaves the agency, patients are linked to the next provider in an adequate time frame so that the patient’s quality of care is not compromised. The new provider is also given notification so that he or she is aware of the transfer of the patient and is able to review the chart in advance.

Along with medication management, we also provide psychotherapy. We utilize a single electronic health record (EHR) throughout the agency and we are able to contribute to changes in the EHR to make it more user-friendly. We have monthly journal club meetings and meetings with other staff members to review and discuss the progress of our organization. There are also numerous online resources through which we can keep ourselves updated with current research and earn CME. Some of the providers at our agency have academic affiliations, and hence there are opportunities to teach medical students and residents who rotate at some of our sites.

Dr. Stanciu: What are some of the more prevalent disorders you encounter?

Dr. Wadhwania: We see a wide range of disorders, such as affective disorders, schizophrenia, and comorbid disorders, specifically comorbid substance use disorders. So we encounter a high number of chronic mental illnesses.

Continue to: What are some challenges in working with this population?

Dr. Stanciu: What are some challenges in working with this population?

Dr. Wadhwania: Based on the high volume of patients we encounter, the resources available in the community are limited. But this challenges us to be creative and maximize what we have available to create new resources, such as having on-site case managers rather than just in the community, and building psychosocial rehabilitation programs near our various clinics for the patients to bring them the best care possible. Other challenges include a lack of education on and awareness of mental illness; there is still a lot of stigma surrounding mental illness in the community.

Dr. Stanciu: How would you describe your experience working in this setting?

Dr. Wadhwania: It’s a very rewarding experience, as you get to be creative, and patients appreciate your efforts. We use a patient-centered approach, and we work as a team. Each team member brings in a unique set of skills, and we bounce ideas off each other. There is a sense of satisfaction when you help people who don’t have easy access to health care. Finally, in a setting like this, young psychiatrists are able to gain more opportunities earlier than they would while working in other settings.

Continue to: How did you career path prepare you to work in such a challenging setting?

Dr. Stanciu: How did your career path prepare you to work in such a challenging setting?

Dr. Wadhwania: While at East Carolina University, teamwork and getting the best treatment for the patient was the goal. We treated an underserved population that did not have easy access to resources, and dealt with the same wide range of psychopathology. So my residency prepared me well to work in my current position.

Dr. Stanciu: How would you describe a psychiatric physician who is well-suited for such a setting?

Dr. Wadhwania: A perfect fit would be someone who is able to harness and build resources for the patients in the community and in the practice and wants to continue to build that skill. This individual is someone who is a team player, is flexible, and has a high professional frustration tolerance. The physician’s main aim would be to serve, and his or her mission would not be monetarily driven.

Continue to: What is the typical reimbursement model for your practice, and do you run into difficulties with health insurance providers in this setting?

Dr. Stanciu: What is the typical reimbursement model for your practice, and do you run into difficulties with health insurance providers in this setting?

Dr. Wadhwania: Approximately 40% of the patients we treat have no health insurance, and approximately 60% have Medicaid or managed Medicaid or Medicare. There is no burden of health insurance. Full-time employees are salaried, and part-time employees are compensated on an hourly model. There is also an incentive bonus system based on quality and productivity.

Dr. Stanciu: What model does your clinic use to overcome the shortage of services?

Dr. Wadhwania: There are approximately 37 medical staff members in the agency, most of whom are MDs, but this group also includes nurse practitioners and clinical nurse specialists, so there is no shortage within our agency. We do contract for telepsychiatry services, but because our agency’s clinics are located throughout the county, most of our patients have easy access to any one of our clinics. We have a number of social workers, therapists, nurses, case managers, and pharmacists. We have a crisis center where unstable patients who require admission to an inpatient unit can be admitted; we also are able to refer patients directly to other inpatient psychiatric units. Our agency also has an addiction clinic and a residential substance abuse program catering specifically to patients with substance use disorders. We have educational, therapeutic, and behavioral support services, including residential services, for patients who have developmental disabilities. Our agency also has residential services for patients who are homeless or have a lower income and would benefit from support in a residential setting.

Our therapists are able to refer patients to state-contracted Assertive Community Treatment teams that serve our county. We are also able to set up intensive case management for patients in the community, as well as other community support services, peer support programs, and psychosocial rehabilitation programs.

Dr. Stanciu: What advice do you have for early career psychiatrists and trainees who are contemplating working in an urban-public setting?

Dr. Wadhwania: First of all, realize that there are many misconceptions about serving in the public sector, such as there is no access to new medications, etc. It is important to establish whether public sector service is “in your heart.” You need to learn the organization’s philosophy, mission, and vision, and figure out whether these views align with yours. Getting to know the leadership and how they value psychiatrists and other staff members is also very important. Also, make sure that there are opportunities for you to become a leader in the organization, that there is room for growth, and that it’s a stable organization.

It is well established that general medical conditions can be associated with various psychiatric disorders. But the reverse is less recognized: That serious mental illness is associated with many physical maladies, often leading to early mortality. Thus, it is a bidirectional medical reality.

The multisystem adverse effects of psycho­tropic medications, such as metabolic dysregulation, often are blamed for the serious medical problems afflicting psychiatrically ill patients. However, evidence is mounting that while iatrogenic effects play a role, the larger effect appears to be due to a genetic link between psychiatric disorders and cardiovascular risk.¹ Unhealthy lifestyles, including sedentary living, poor dietary habits, smoking, and alcohol/substance use, also play a role in the rapid deterioration of physical health and early mortality of individuals afflicted by mood disorders, psychotic disorders, and anxiety disorders. The mantra of “healthy body, healthy mind” is well known, but “unhealthy mind, unhealthy body” should be equally emphasized as a reason for high morbidity and premature mortality in patients with serious mental disorders.

Consider the following alarming findings:

• A recent study revealed that even before the onset of the first psychotic episode, young patients with schizophrenia already suffer from a wide variety of medical conditions.² In a large sample of 954,351 Danish persons followed from birth to adulthood, of whom 4,371 developed schizophrenia, 95.6% of patients with schizophrenia had a history of hospitalization for somatic problems, including gastrointestinal, endocrine, genitourinary, metabolic, and circulatory system diseases; cancer; and epilepsy. Those findings suggest genetic, physiological, immunological, or developmental overlap between schizophrenia and medical conditions.
• A survey of 67,609 individuals with mood, anxiety, eating, impulse control, or substance use disorders followed for 10 years found that persons with those psychiatric disorders had a significantly higher risk of chronic medical conditions, including heart disease, stroke, hypertension, diabetes, asthma, arthritis, lung disease, peptic ulcer, and cancer.³
• A 7-year follow-up study of 1,138,853 individuals with schizophrenia in the United States found a 350% increase in mortality among this group of patients, who ranged in age from 20 to 64 years, compared with the general population, matched for age, sex, race, ethnicity, and geographic regions.⁴ An editorial accompanying this study urged psychiatrists to urgently address the “deadly consequences” of major psychiatric disorders.⁵
• A study of 18,380 individuals with schizophrenia, schizoaffective disorder, or bipolar disorder in London found that these patients were frequently hospitalized for general medical conditions, most commonly urinary, digestive, respiratory, endocrine/metabolic, hematologic, neurologic, dermatologic, and infectious disorders, neoplasm, and poisoning.⁶ The authors attributed those nonpsychiatric hospitalizations to self-neglect, self-harm, and poor health care access, as well as to “medically unexplained” causes.
• An extremely elevated mortality rate (24-fold higher than the general population) was reported in a 12-month study of young individuals (age 16 to 30 years) diagnosed with psychosis.⁷ The investigators also found that 61% of the cohort did not fill their antipsychotic prescriptions during that year, and 62% had ≥1 hospitalizations and/or emergency room visits during that year. The relationship between high mortality and lack of treatment with antipsychotics in schizophrenia was confirmed by another recent study,⁸ a 7-year follow-up of 29,823 persons with schizophrenia in Sweden that measured all-cause mortality. These researchers found the highest mortality among patients not receiving any antipsychotics, while the lowest mortality was among those receiving a long-acting injectable second-generation antipsychotic.
• A recent systematic review of 16 studies that examined glucose homeostasis in first-episode psychosis⁹ revealed that even at the onset of schizophrenia, glucose homeostasis was already altered, suggesting that predisposition to type 2 diabetes mellitus is a medical condition associated with schizophrenia, and not simply an iatrogenic effect of antipsychotic pharmacotherapy. This adds fodder to the possibility of a genetic overlap between schizophrenia and somatic disorders, including diabetes.¹⁰
• In a meta-analysis of 47 studies of young people at “ultra-high risk” for schizophrenia, cardiovascular risk was found to be high, mostly as a result of lifestyle factors such as low levels of physical activity and high rates of smoking and alcohol use, even before the onset of psychosis.¹¹
• The risk of stroke was found to be higher in 80,569 patients with schizophrenia compared with 241,707 age- and sex-matched control subjects.¹²
• A meta-analysis of the risk of stroke in 6 cohorts with schizophrenia found that there is a higher risk for stroke in schizophrenia, and that this may be related to natural history of the illness itself, not just due to comorbid metabolic risk factors.¹³
• The high rate of cardiovascular disease in depression has been attributed to neuroinflammation¹⁴ or possibly to increased platelet reactivity.¹⁵

As psychiatric physicians, we always screen our patients for past and current medical conditions that are comorbid with their psychiatric disorders. We are aware of the lifestyle factors that increase these patients’ physical morbidity and mortality, above and beyond their suicide-related mortality. Our patients with schizophrenia and mood disorders have triple the smoking rates of the general population, and they tend to be sedentary with poor eating habits that lead to obesity, obstructive sleep apnea, diabetes, hypertension, and dyslipidemia, which increases their risk for heart attack, stroke, and cancer. Self-neglect during acute episodes of depression or psychosis increases the risk of infection, malnutrition, and tooth decay. We also see skin damage in obsessive-compulsive disorder patients who are compelled to wash their hands numerous times a day, the life-threatening effects of anorexia nervosa, and various types of medical ailments caused by incomplete suicidal attempts. Poverty and substance use among chronically mentally ill patients also increase the odds of physical ailments.

So we need to act diligently to reduce the alarming medical morbidity and mortality of the psychiatric population. Collaborative care with a primary care provider is a must, not an option, for every patient, because studies indicate that without collaborative care, patients receive inadequate primary care.¹⁶ Providing rapid access to standard medical care is the single most critical step for the prevention or amelioration of physical disorders in our psychiatric patients, concurrently with stabilizing their ailing brains and minds. If we focus only on treating psychopathology, then we will win the battle against mental illness, but lose the war of life and death.

It is well established that general medical conditions can be associated with various psychiatric disorders. But the reverse is less recognized: That serious mental illness is associated with many physical maladies, often leading to early mortality. Thus, it is a bidirectional medical reality.

The multisystem adverse effects of psycho­tropic medications, such as metabolic dysregulation, often are blamed for the serious medical problems afflicting psychiatrically ill patients. However, evidence is mounting that while iatrogenic effects play a role, the larger effect appears to be due to a genetic link between psychiatric disorders and cardiovascular risk.¹ Unhealthy lifestyles, including sedentary living, poor dietary habits, smoking, and alcohol/substance use, also play a role in the rapid deterioration of physical health and early mortality of individuals afflicted by mood disorders, psychotic disorders, and anxiety disorders. The mantra of “healthy body, healthy mind” is well known, but “unhealthy mind, unhealthy body” should be equally emphasized as a reason for high morbidity and premature mortality in patients with serious mental disorders.

Consider the following alarming findings:

• A recent study revealed that even before the onset of the first psychotic episode, young patients with schizophrenia already suffer from a wide variety of medical conditions.² In a large sample of 954,351 Danish persons followed from birth to adulthood, of whom 4,371 developed schizophrenia, 95.6% of patients with schizophrenia had a history of hospitalization for somatic problems, including gastrointestinal, endocrine, genitourinary, metabolic, and circulatory system diseases; cancer; and epilepsy. Those findings suggest genetic, physiological, immunological, or developmental overlap between schizophrenia and medical conditions.
• A survey of 67,609 individuals with mood, anxiety, eating, impulse control, or substance use disorders followed for 10 years found that persons with those psychiatric disorders had a significantly higher risk of chronic medical conditions, including heart disease, stroke, hypertension, diabetes, asthma, arthritis, lung disease, peptic ulcer, and cancer.³
• A 7-year follow-up study of 1,138,853 individuals with schizophrenia in the United States found a 350% increase in mortality among this group of patients, who ranged in age from 20 to 64 years, compared with the general population, matched for age, sex, race, ethnicity, and geographic regions.⁴ An editorial accompanying this study urged psychiatrists to urgently address the “deadly consequences” of major psychiatric disorders.⁵
• A study of 18,380 individuals with schizophrenia, schizoaffective disorder, or bipolar disorder in London found that these patients were frequently hospitalized for general medical conditions, most commonly urinary, digestive, respiratory, endocrine/metabolic, hematologic, neurologic, dermatologic, and infectious disorders, neoplasm, and poisoning.⁶ The authors attributed those nonpsychiatric hospitalizations to self-neglect, self-harm, and poor health care access, as well as to “medically unexplained” causes.
• An extremely elevated mortality rate (24-fold higher than the general population) was reported in a 12-month study of young individuals (age 16 to 30 years) diagnosed with psychosis.⁷ The investigators also found that 61% of the cohort did not fill their antipsychotic prescriptions during that year, and 62% had ≥1 hospitalizations and/or emergency room visits during that year. The relationship between high mortality and lack of treatment with antipsychotics in schizophrenia was confirmed by another recent study,⁸ a 7-year follow-up of 29,823 persons with schizophrenia in Sweden that measured all-cause mortality. These researchers found the highest mortality among patients not receiving any antipsychotics, while the lowest mortality was among those receiving a long-acting injectable second-generation antipsychotic.
• A recent systematic review of 16 studies that examined glucose homeostasis in first-episode psychosis⁹ revealed that even at the onset of schizophrenia, glucose homeostasis was already altered, suggesting that predisposition to type 2 diabetes mellitus is a medical condition associated with schizophrenia, and not simply an iatrogenic effect of antipsychotic pharmacotherapy. This adds fodder to the possibility of a genetic overlap between schizophrenia and somatic disorders, including diabetes.¹⁰
• In a meta-analysis of 47 studies of young people at “ultra-high risk” for schizophrenia, cardiovascular risk was found to be high, mostly as a result of lifestyle factors such as low levels of physical activity and high rates of smoking and alcohol use, even before the onset of psychosis.¹¹
• The risk of stroke was found to be higher in 80,569 patients with schizophrenia compared with 241,707 age- and sex-matched control subjects.¹²

How precision psychiatry helped my patient

I applaud Dr. Nasrallah’s editorial “The dawn of precision psychiatry” (From the Editor, Current Psychiatry. December 2017, p. 7-8,11). Since the late 1990s, I have been practicing psychiatry in this mode in increasingly greater degree. I thought you would be interested in a recent case that demonstrates the application of precision psychiatry in an adolescent patient previously diagnosed with an attention disorder, an anxiety disorder, and a possible dissociative disorder.

Ms. G, age 14, presented with periodic emotional “meltdowns,” which would occur in any setting, and I determined that they were precipitated by a high glycemic intake. By carefully controlling her glycemic intake and starting her on caprylic acid (a medium-chain triglyceride, which was used to maintain a ketotic state), 1 tablespoon 3 times daily, we were able to reduce the frequency of her episodes by 80% to 90%. Using data from commercially available DNA testing, I determined that she had single nucleotide polymorphisms (SNPs) in an alpha-ketoglutarate dehydrogenase gene, which is primarily located in the prefrontal cortex (PFC), and whose function is supported by thiamine and impaired by high glycemic intake.¹ After adding oral thiamine hydrochloride, 100 mg twice a day, and correcting other abnormalities (eg, she was hypothyroid), her episodes are now rare. She is functioning well, has been getting high grades, and recently wrote a 40-page short story.

Once she improved, she was able to describe having a partial seizure, with a rising sensation, which often improves with ketosis. Clearly, disruption of her PFC energetics due to the SNPs described above contributed to the disinhibition of the temporal lobe structures. Furthermore, she has an APOE3/4 status, which puts her at risk for Alzheimer’s disease. Her mother was educated about the importance of good health habits, which is personalized and preventative medicine.

Ketamine: The next ‘opioid crisis’?

The chief of the FDA, Scott Gottlieb, MD, recently discussed the need to learn from the mistakes that contributed to the current opioid epidemic¹ and how to curb this crisis. Understanding some of the potential pitfalls could help us prevent, or better manage, the next crisis. Despite the bad press about the opioid crisis,² there seems to be growing promise of another: ketamine. Although ketamine is classified as a Schedule III drug by the Drug Enforcement Agency³ and has a well-documented potential for dependency,⁴ this medication is now being considered a potential treatment for acute suicidality and depression.

There are many similarities between the use of opioids to treat pain and the potential use of ketamine to treat suicidality. Physical and mental pain are subjective, qualitative, and difficult to quantify, which makes it difficult to develop accurate measurements of symptom severity. Chronic physical pain and suicidality are not illnesses, but symptoms of myriad types of pathologies with differing etiologies and treatment options.⁵ Due to the ambiguous and subjective experience of physical and mental pain, we tend to lump them together as 1 pathological category without understanding pathophysiologic differences. The most commonly reported types of pain include low back pain, migraine/headache, neck pain, and facial pain.⁶ However, each of these pain types would likely have a different pathophysiology and treatment. Likewise, suicide can be associated with various psychiatric conditions,⁷ and suicidality resulting from these conditions may require a different etiology and treatment.

We already know that both opioids and ketamine are addictive. For example, there is a report of a nurse stealing a hospital’s supply of ketamine and self-treating for depression, which led to an inpatient detox admission after she developed toxicity and addiction.⁸ Some ketamine research supports its safe use, but it may be biased due to conflicts of interest. For example, several authors of a recent study proclaiming the effectiveness of a single dose of ketamine in treating suicidal ideation are named on patents or are employed by companies named on patents related to ketamine and would financially benefit from FDA-approval of ketamine for the treatment of psychiatric disorders.⁹

Warnings stating how both opioid and ketamine should be used were published years ago but have since been ignored. For example, a 1977 article advocated that opioids should only be used for a “short duration and limited to patients with acute diseases or inoperable or metastatic cancer who require long-term relief.”¹⁰ The rationale for this distinction was foretelling of the current opioid epidemic: “Continued and prolonged use of narcotics in patients with chronic benign pain is not recommended because of serious behavioral consequences, the development of tolerance, and addiction liability. Long-term use of analgesic drugs in chronic pain usually produces negative behavioral complications that are more difficult to manage than the pain it was desired to eliminate.”¹⁰ We knew better then.

The earliest report of ketamine dependency I could find was published in 1987, which predates its classification as a controlled substance.¹¹ More recently, ketamine dependency has been associated with adverse effects that are similar to “not only cocaine and amphetamine but also with opiates, alcohol and cannabis, as well as the psychological attractions of its distinctive psychedelic properties.”¹² We should consider ourselves warned.

Ketamine: The next ‘opioid crisis’?

The chief of the FDA, Scott Gottlieb, MD, recently discussed the need to learn from the mistakes that contributed to the current opioid epidemic¹ and how to curb this crisis. Understanding some of the potential pitfalls could help us prevent, or better manage, the next crisis. Despite the bad press about the opioid crisis,² there seems to be growing promise of another: ketamine. Although ketamine is classified as a Schedule III drug by the Drug Enforcement Agency³ and has a well-documented potential for dependency,⁴ this medication is now being considered a potential treatment for acute suicidality and depression.

There are many similarities between the use of opioids to treat pain and the potential use of ketamine to treat suicidality. Physical and mental pain are subjective, qualitative, and difficult to quantify, which makes it difficult to develop accurate measurements of symptom severity. Chronic physical pain and suicidality are not illnesses, but symptoms of myriad types of pathologies with differing etiologies and treatment options.⁵ Due to the ambiguous and subjective experience of physical and mental pain, we tend to lump them together as 1 pathological category without understanding pathophysiologic differences. The most commonly reported types of pain include low back pain, migraine/headache, neck pain, and facial pain.⁶ However, each of these pain types would likely have a different pathophysiology and treatment. Likewise, suicide can be associated with various psychiatric conditions,⁷ and suicidality resulting from these conditions may require a different etiology and treatment.

We already know that both opioids and ketamine are addictive. For example, there is a report of a nurse stealing a hospital’s supply of ketamine and self-treating for depression, which led to an inpatient detox admission after she developed toxicity and addiction.⁸ Some ketamine research supports its safe use, but it may be biased due to conflicts of interest. For example, several authors of a recent study proclaiming the effectiveness of a single dose of ketamine in treating suicidal ideation are named on patents or are employed by companies named on patents related to ketamine and would financially benefit from FDA-approval of ketamine for the treatment of psychiatric disorders.⁹

Warnings stating how both opioid and ketamine should be used were published years ago but have since been ignored. For example, a 1977 article advocated that opioids should only be used for a “short duration and limited to patients with acute diseases or inoperable or metastatic cancer who require long-term relief.”¹⁰ The rationale for this distinction was foretelling of the current opioid epidemic: “Continued and prolonged use of narcotics in patients with chronic benign pain is not recommended because of serious behavioral consequences, the development of tolerance, and addiction liability. Long-term use of analgesic drugs in chronic pain usually produces negative behavioral complications that are more difficult to manage than the pain it was desired to eliminate.”¹⁰ We knew better then.

The earliest report of ketamine dependency I could find was published in 1987, which predates its classification as a controlled substance.¹¹ More recently, ketamine dependency has been associated with adverse effects that are similar to “not only cocaine and amphetamine but also with opiates, alcohol and cannabis, as well as the psychological attractions of its distinctive psychedelic properties.”¹² We should consider ourselves warned.

CASE Auditory hallucinations?

M, age 10, has had multiple visits to the pediatric emergency department (PED) with the chief concern of excessive urinary frequency. At each visit, the medical workup has been negative and he was discharged home. After a few months, M’s parents bring their son back to the PED because he reports hearing “voices in my head” and “feeling tense and scared.” When these feelings become too overwhelming, M stops eating and experiences substantial fear and anxiety that require his mother’s repeated reassurances. M’s mother reports that 2 weeks before his most recent PED visit, he became increasingly anxious and disturbed, and said he was afraid most of the time, and worried about the safety of his family for no apparent reason.

The psychiatrist evaluates M in the PED and diagnoses him with unspecified schizophrenia spectrum and other psychotic disorder based on his persistent report of auditory and tactile hallucinations, including hearing a voice of a man telling him he was going to choke on his food and feeling someone touch his arm to soothe him during his anxious moments. M does not meet criteria for acute inpatient hospitalization, and is discharged home with referral to follow-up at our child and adolescent psychiatry outpatient clinic.

On subsequent evaluation in our clinic, M reports most of the same about his experience hearing “voices in my head” that repeatedly suggest “I might choke on my food and end up seriously ill in the hospital.” He started to hear the “voices” after he witnessed his sister choke while eating a few days earlier. He also mentions that the “voices” tell him “you have to use the restroom.” As a result, he uses the restroom several times before leaving for home and is frequently late for school. His parents accommodate his behavior—his mother allows him to use the bathroom multiple times, and his father overlooks the behavior as part of school anxiety.

At school, his teacher reports a concern for attention-deficit/hyperactivity disorder (ADHD) based on M’s continuous inattentiveness in class and dropping grades. He asks for bathroom breaks up to 15 times a day, which disrupts his class work.

These behaviors have led to a gradual 1-year decline in his overall functioning, including difficulty at school for requesting too many bathroom breaks; having to repeat the 3rd grade; and incurring multiple hospital visits for evaluation of his various complaints. M has become socially isolated and withdrawn from friends and family.

M’s developmental history is normal and his family history is negative for any psychiatric disorder. Medical history and physical examination are unremarkable. CT scan of his head is unremarkable, and all hematologic and biochemistry laboratory test values are within normal range.

The authors’ observations

Several factors may contribute to an increased chance of misdiagnosis of a psychiatric illness, especially when evaluating children. Compared with adults, children have a limited ability to explain their symptoms, and given their limited cognitive capacity, they may have difficulty identifying their symptoms as functionally limiting. A comprehensive clinical evaluation, including detailed interviews with the patient, the patient’s parents, and if possible, the patient’s teachers, is required to assess the child’s symptomatology and make an accurate clinical diagnosis.

On closer sequential evaluations with M and his family, we determined that the “voices” he was hearing were actually intrusive thoughts, and not hallucinations. M clarified this by saying that first he feels a “pressure”-like sensation in his head, followed by repeated intrusive thoughts of voiding his bladder that compel him to go to the restroom to try to urinate. He feels temporary relief after complying with the urge, even when he passes only a small amount of urine or just washes his hands. After a brief period of relief, this process repeats itself. Further, he was able to clarify his experience while eating food, where he first felt a “pressure”-like sensation in his head, followed by intrusive thoughts of choking that result in him not eating.

This led us to a more appropriate diagnosis of OCD (Table 1¹). The incidence of OCD has 2 peaks, with different gender distributions. The first peak occurs in childhood, with symptoms mostly arising between 7 and 12 years of age and affecting boys more often than girls. The second peak occurs in early adulthood, at a mean age of 21 years, with a slight female majority.² However, OCD is often under recognized and undertreated, perhaps due to its extensive heterogeneity; symptom presentations and comorbidity patterns can vary noticeably between individual patients as well as age groups.

OCD is characterized by the presence of obsessions or compulsions that wax and wane in severity, are time-consuming (at least 1 hour per day), and cause subjective distress or interfere with life of the patient or the family. Adults with OCD recognize at some level that the obsessions and/or compulsions are excessive and unreasonable, although children are not required to have this insight to meet criteria for the diagnosis.¹ Rating scales, such as the Children’s Yale-Brown Obsessive-Compulsive Scale, Dimensional Yale-Brown Obsessive-Compulsive Scale, and Family Accommodation Scale, are useful to obtain detailed information regarding OCD symptoms, tics, and other factors relevant to the diagnosis.

Continue to: M's symptomatology...

M’s symptomatology did not appear to be psychotic. He was screened for positive or negative symptoms of psychosis, which he and his family clearly denied. Moreover, M’s compulsions (going to the restroom) were typically performed in response to his obsessions (urge to void his bladder) to reduce his distress, which is different from schizophrenia, in which repetitive behaviors are performed in response to psychotic ideation, and not obsessions (Table 2^3-5).

M’s inattentiveness in the classroom was found to be related to his obsessions and compulsions, and not part of a symptom cluster characterizing ADHD. Teachers often interpret inattention and poor classroom performance as ADHD, but having detailed conversations with teachers often is helpful in understanding the nature of a child’s symptomology and making the appropriate diagnosis.

Establishing the correct clinical diagnosis is critical because it is the starting point in treatment. First-line medication for one condition may exacerbate the symptoms of others. For example, in addition to having a large adverse-effect burden, antipsychotics can induce de novo obsessive–compulsive symptoms (OCS) or exacerbate preexisting OCS, and selective serotonin reuptake inhibitors (SSRIs) may exacerbate psychosis in schizo-obsessive patients with a history of impulsivity and aggressiveness.⁶ Similarly, stimulant medications for ADHD may exacerbate OCS and may even induce them on their own.^7,8

The authors’ observations

Studies have reported an average of 2.5 years from the onset of OCD symptoms to diagnosis in the United States.⁹ A key reason for this delay, which is more frequently encountered in pediatric patients, is secrecy. Children often feel embarrassed about their symptoms and conceal them until the interference with their functioning becomes extremely disabling. In some cases, symptoms may closely resemble normal childhood routines. In fact, some repetitive behaviors may be normal in some developmental stages, and OCD could be conceptualized as a pathological condition with continuity of normal behaviors during different developmental periods.¹⁰

Also, symptoms may go unnoticed for quite some time as unsuspecting and well-intentioned parents and family members become overly involved in the child’s rituals (eg, allowing for increasing frequent prolonged bathroom breaks or frequent change of clothing, etc.). This well-established phenomenon, termed accommodation, is defined as participation of family members in a child’s OCD–related rituals.¹¹ Especially when symptoms are mild or the child is functioning well, accommodation can make it difficult for parents to realize the presence or nature of a problem, as they might tend to minimize their child’s symptoms as representing a unique personality trait or a special “quirk.” Parents generally will seek treatment when their child’s symptoms become more impairing and begin to interfere with social functioning, school performance, or family functioning.

The clinical picture is further complicated by comorbidity. Approximately 60% to 80% of children and adolescents with OCD have ≥1 comorbid psychiatric disorders. Some of the most common include tic disorders, ADHD, anxiety disorders, and mood or eating disorders.⁹

TREATMENT Combination therapy

In keeping with American Academy of Child and Adolescent Psychiatry guidelines on treating OCD (Table 3¹²), we start M on fluoxetine 10 mg/d. He also begins CBT. Fluoxetine is slowly titrated to 40 mg/d while M engages in learning and utilizing CBT techniques to manage his OCD.

The authors’ observations

The combination of CBT and medication has been suggested as the treatment of choice for moderate and severe OCD.¹² The Pediatric OCD Treatment Study, a 5-year, 3-site outcome study designed to compare placebo, sertraline, CBT, and combined CBT and sertraline, concluded that the combined treatment (CBT plus sertraline) was more effective than CBT alone or sertraline alone.¹³ The effect sizes for the combined treatment, CBT alone, and sertraline alone were 1.4, 0.97, and 0.67, respectively. Remission rates for SSRIs alone are <33%.^13,14

SSRIs are the first-line medication for OCD in children, adolescents, and adults (Table 3¹²). Well-designed clinical trials have demonstrated the efficacy and safety of the SSRIs fluoxetine, sertraline, and fluvoxamine (alone or combined with CBT) in children and adolescents with OCD.¹³ Other SSRIs, such as citalopram, paroxetine, and escitalopram, also have demonstrated efficacy in children and adolescents with OCD, even though the FDA has not yet approved their use in pediatric patients.¹² Despite a positive trial of paroxetine in pediatric OCD,¹² there have been concerns related to its higher rates of treatment-emergent suicidality,¹⁵ lower likelihood of treatment response,¹⁶ and its particularly short half-life in pediatric patients.¹⁷

Clomipramine is a tricyclic antidepressant with serotonergic properties that is used alone or to boost the effect of an SSRI when there is a partial response. It should be introduced at a low dose in pediatric patients (before age 12) and closely monitored for anticholinergic and cardiac adverse effects. A systemic review and meta-analysis of early treatment responses of SSRIs and clomipramine in pediatric OCD indicated that the greatest benefits occurred early in treatment.¹⁸ Clomipramine was associated with a greater measured benefit compared with placebo than SSRIs; there was no evidence of a relationship between SSRI dosing and treatment effect, although data were limited. Adults and children with OCD demonstrated a similar degree and time course of response to SSRIs in OCD.¹⁸

Treatment should start with a low dose to reduce the risk of adverse effects with an adequate trial for 10 to 16 weeks at adequate doses. Most experts suggest that treatment should continue for at least 12 months after symptom resolution or stabilization, followed by a very gradual cessation.¹⁹

OUTCOME Improvement in functioning

After 12 months of combined CBT and fluoxetine, M’s global assessment of functioning (GAF) scale score improves from 35 to 80, indicating major improvement in overall functional level.

Bottom Line

Obsessive-compulsive disorder may masquerade as a schizophrenia spectrum disorder, particularly in younger patients. Accurate differentiation is crucial because antipsychotics can induce de novo obsessive-compulsive symptoms (OCS) or exacerbate preexisting OCS, and selective serotonin reuptake inhibitors may exacerbate psychosis in schizo-obsessive patients with a history of impulsivity and aggressiveness.

Adults with OCD recognize at some level that the obsessions and/or compulsions are excessive and unreasonable, although children are not required to have this insight to meet criteria for the diagnosis.¹ Rating scales, such as the Children’s Yale-Brown Obsessive-Compulsive Scale, Dimensional Yale-Brown Obsessive-Compulsive Scale, and Family Accommodation Scale, are useful to obtain detailed information regarding OCD symptoms, tics, and other factors relevant to the diagnosis.

Continue to: M's symptomatology...

M’s symptomatology did not appear to be psychotic. He was screened for positive or negative symptoms of psychosis, which he and his family clearly denied. Moreover, M’s compulsions (going to the restroom) were typically performed in response to his obsessions (urge to void his bladder) to reduce his distress, which is different from schizophrenia, in which repetitive behaviors are performed in response to psychotic ideation, and not obsessions (Table 2^3-5).

M’s inattentiveness in the classroom was found to be related to his obsessions and compulsions, and not part of a symptom cluster characterizing ADHD. Teachers often interpret inattention and poor classroom performance as ADHD, but having detailed conversations with teachers often is helpful in understanding the nature of a child’s symptomology and making the appropriate diagnosis.

Establishing the correct clinical diagnosis is critical because it is the starting point in treatment. First-line medication for one condition may exacerbate the symptoms of others. For example, in addition to having a large adverse-effect burden, antipsychotics can induce de novo obsessive–compulsive symptoms (OCS) or exacerbate preexisting OCS, and selective serotonin reuptake inhibitors (SSRIs) may exacerbate psychosis in schizo-obsessive patients with a history of impulsivity and aggressiveness.⁶ Similarly, stimulant medications for ADHD may exacerbate OCS and may even induce them on their own.^7,8

The authors’ observations

Studies have reported an average of 2.5 years from the onset of OCD symptoms to diagnosis in the United States.⁹ A key reason for this delay, which is more frequently encountered in pediatric patients, is secrecy. Children often feel embarrassed about their symptoms and conceal them until the interference with their functioning becomes extremely disabling. In some cases, symptoms may closely resemble normal childhood routines. In fact, some repetitive behaviors may be normal in some developmental stages, and OCD could be conceptualized as a pathological condition with continuity of normal behaviors during different developmental periods.¹⁰

Also, symptoms may go unnoticed for quite some time as unsuspecting and well-intentioned parents and family members become overly involved in the child’s rituals (eg, allowing for increasing frequent prolonged bathroom breaks or frequent change of clothing, etc.). This well-established phenomenon, termed accommodation, is defined as participation of family members in a child’s OCD–related rituals.¹¹ Especially when symptoms are mild or the child is functioning well, accommodation can make it difficult for parents to realize the presence or nature of a problem, as they might tend to minimize their child’s symptoms as representing a unique personality trait or a special “quirk.” Parents generally will seek treatment when their child’s symptoms become more impairing and begin to interfere with social functioning, school performance, or family functioning.

The clinical picture is further complicated by comorbidity. Approximately 60% to 80% of children and adolescents with OCD have ≥1 comorbid psychiatric disorders. Some of the most common include tic disorders, ADHD, anxiety disorders, and mood or eating disorders.⁹

TREATMENT Combination therapy

In keeping with American Academy of Child and Adolescent Psychiatry guidelines on treating OCD (Table 3¹²), we start M on fluoxetine 10 mg/d. He also begins CBT. Fluoxetine is slowly titrated to 40 mg/d while M engages in learning and utilizing CBT techniques to manage his OCD.

The authors’ observations

The combination of CBT and medication has been suggested as the treatment of choice for moderate and severe OCD.¹² The Pediatric OCD Treatment Study, a 5-year, 3-site outcome study designed to compare placebo, sertraline, CBT, and combined CBT and sertraline, concluded that the combined treatment (CBT plus sertraline) was more effective than CBT alone or sertraline alone.¹³ The effect sizes for the combined treatment, CBT alone, and sertraline alone were 1.4, 0.97, and 0.67, respectively. Remission rates for SSRIs alone are <33%.^13,14

SSRIs are the first-line medication for OCD in children, adolescents, and adults (Table 3¹²). Well-designed clinical trials have demonstrated the efficacy and safety of the SSRIs fluoxetine, sertraline, and fluvoxamine (alone or combined with CBT) in children and adolescents with OCD.¹³ Other SSRIs, such as citalopram, paroxetine, and escitalopram, also have demonstrated efficacy in children and adolescents with OCD, even though the FDA has not yet approved their use in pediatric patients.¹² Despite a positive trial of paroxetine in pediatric OCD,¹² there have been concerns related to its higher rates of treatment-emergent suicidality,¹⁵ lower likelihood of treatment response,¹⁶ and its particularly short half-life in pediatric patients.¹⁷

Clomipramine is a tricyclic antidepressant with serotonergic properties that is used alone or to boost the effect of an SSRI when there is a partial response. It should be introduced at a low dose in pediatric patients (before age 12) and closely monitored for anticholinergic and cardiac adverse effects. A systemic review and meta-analysis of early treatment responses of SSRIs and clomipramine in pediatric OCD indicated that the greatest benefits occurred early in treatment.¹⁸ Clomipramine was associated with a greater measured benefit compared with placebo than SSRIs; there was no evidence of a relationship between SSRI dosing and treatment effect, although data were limited. Adults and children with OCD demonstrated a similar degree and time course of response to SSRIs in OCD.¹⁸

Treatment should start with a low dose to reduce the risk of adverse effects with an adequate trial for 10 to 16 weeks at adequate doses. Most experts suggest that treatment should continue for at least 12 months after symptom resolution or stabilization, followed by a very gradual cessation.¹⁹

OUTCOME Improvement in functioning

After 12 months of combined CBT and fluoxetine, M’s global assessment of functioning (GAF) scale score improves from 35 to 80, indicating major improvement in overall functional level.

Bottom Line

Obsessive-compulsive disorder may masquerade as a schizophrenia spectrum disorder, particularly in younger patients. Accurate differentiation is crucial because antipsychotics can induce de novo obsessive-compulsive symptoms (OCS) or exacerbate preexisting OCS, and selective serotonin reuptake inhibitors may exacerbate psychosis in schizo-obsessive patients with a history of impulsivity and aggressiveness.

Written communication is an essential skill for a consultation-liaison (C-L) psychiatrist, but unfortunately, how to write a consultation note is not part of formal didactics in medical school or residency training.¹ Documentation of a consultation note is a permanent medical record entry that conveys current physician-to-physician information. While considerable literature describes the consultation process, little has been published about composing a consultation note.^1,2 Residents and clinicians who do not have frequent consultations may be unfamiliar with the consultation environment and their role as an expert consultant. Therefore, more explicit guidance on documentation and optimal formatting of the consultation note is needed.

The Box provides an outline for completing the Recommendations/Treatment Plan section of psychiatric consultation notes. When providing your recommendations, it is best to use bullet points, numbering, or bold text; do not bury the information in a dense paragraph.³ Be sure to address each of the following 6 elements.

1. Primary consult concern. The first section of the Recommendations section should include the reason for the consult, which may be the most important part of the consultation process.^1,2 It is important to recognize that an unclear consult question may be a sign of the primary team’s knowledge gap in psychiatry. The role of the C-L psychiatrist is to help the primary team organize their thoughts and concerns regarding their patient to decide on the final consult question.¹ The active consult question may change as clinical issues evolve.

2. Safety and critical issues. Include an assessment of or recommendation on safety and critical issues. An important consideration is whether to recommend a patient sitter and to provide a reason for this recommendation. Occasionally, critical issues are more pressing than the primary consult concern. For example, there are several situations in which abnormal laboratory values and acute medical issues manifest as psychiatric symptoms, including hyponatremia, hypoglycemia, hypotension, low oxygen saturation, or infection. The connection between the 2 may not be clear to the primary treatment team; thus, include a statement to draw their attention to this.

3. Nonpharmacologic recommendations. To provide comprehensive care, consider all treatment modalities, and consider recruiting additional clinical disciplines, as appropriate. Patients may have complex medical and psychiatric presentations that are difficult to differentiate; therefore, C-L psychiatrists should not hesitate to recommend consults from other medical specialists as needed. Likewise, dealing with psychiatric concerns often is difficult for clinicians in other specialties. When possible, it may be helpful to provide brief recommendations about how to approach the patient to diffuse negative emotions and reactions among the treatment team.

4. Psychopharmacology. In this section, the C-L psychiatrist should provide information on the use of any psychotropic medications and an explanation of their indications. If there are discrepancies between a patient’s home and hospital-ordered medications, clarify which medications the patient should be taking while hospitalized. If the C-L treatment team recommends initiating a new medication, provide details regarding the specific medication, dose, route, administration time, and titration schedule, as well as the specific situation for any as-needed medications. It is important to include the indication for any recommended medications, as well as any potential adverse effects. If psychotropic medications are not indicated, add a statement to emphasize this.

5. Social work support. Document any issues that need to be clarified by social work. This might include clarification of a patient’s insurance coverage, current living situation, or durable power of attorney. Also, document how the treatment team would prefer social work to assist with the patient’s care by (for example) providing the patient with resources for outpatient mental health and/or substance abuse treatment or housing options.

Continue to: Disposition

6. Disposition. Finally, include a recommendation regarding disposition. If transfer to a psychiatric facility is not indicated, provide a statement to affirm this. If transfer to a psychiatric facility is recommended, include a discussion of the patient’s appropriateness in the assessment and recommendations. It is helpful to inform the primary team of criteria that may or may not allow the patient to transfer to or be accepted by a psychiatry unit (eg, the patient will need to be off IV medications and able to tolerate oral intake prior to transfer). When transfer is not possible, communicate the reason to the primary treatment team and other ancillary staff.

Communicating responsibilities and expectations

After concluding the Recommendations section, end the consultation note with a brief sentence of gratitude (eg, “Thank you for this consultation and allowing us to assist in the care of your patient.”) and a comment regarding the C-L treatment team’s plan for follow-up. Also, include your contact information in case the primary treatment team has any questions or concerns.

The Recommendations section of a psychiatric consultation note is vital to convey current physician-to-physician recommendations. With the potential complexities in assessing and caring for a medically ill patient with comorbid psychiatric diagnoses, psychiatrists with less C-L experience may be unfamiliar with the essential elements of a consultation note. It is helpful to use a Template to ensure that the consultation and documentation are complete.

Tardive dyskinesia (TD) is an elusive-to-treat adverse effect of antipsychotics that has caused extreme discomfort (in a literal and figurative sense) for patients and their psychiatrists. In 2017, the prevalence of TD as a result of exposure to dopamine antagonists was approximately 30% with first-generation antipsychotics and 20% with second-generation antipsychotics.¹ There have been several effective attempts at reducing rates of TD, including lowering the dosing, shifting to second-generation antipsychotics, and using recently introduced pharmacologic treatments for TD. The past 2 years have seen increased efforts at treating this often-irreversible adverse effect with pharmacotherapy, such as the recently marketed vesicular monoamine transporter-2 (VMAT2) inhibitors valbenazine and deutetrabenazine, as well as the supplement Ginkgo biloba,² although issues with cost, adverse effects, or drug–drug interactions could limit the benefits of these agents.

Despite these strategies, one approach has been largely overlooked: prevention. Although it is included in many guidelines and literature reports, prevention has become less of a standard of practice and more of a cliché. Prevention is the key strategy for lowering the rate of TD, and it should be the assumed responsibility of each clinician in every prescription they write throughout the entire continuum of care. Here, we provide steps to take to help prevent TD, and what to consider when TD occurs.

1. Realize that we are all responsible for TD. We know TD exists, but we often feel that this adverse effect is not our fault. Avoid adapting a philosophy of “someone else caused it,” “they didn’t cause it yet,” or “it’s going to happen anyway.” We must remember that every unnecessary exposure to a dopamine antagonist increases the risk of TD, even if we don’t see the adverse effect firsthand.

2. Treat first-episode psychosis early and aggressively. Doing so may prevent chronicity of the illness, which would save a patient from long-term, high-dose exposure to antipsychotics. Lower the risk of TD with atypical antipsychotics and offer long-acting injectables when possible to improve medication adherence.

3. Treat both acute and chronic symptoms of psychosis throughout the continuum of care. The choice of medication and dose should be reevaluated at each interaction to enhance improvement of acute symptoms and to minimize chronic adverse effects. Always recognize the differences in aggressive treatment of an acute episode of psychosis vs maintenance treatment of baseline symptoms. Also, assess for TD by conducting abnormal involuntary movement scale (AIMS) examinations at baseline and at least biannually.

4. Use clozapine instead of 2 antipsychotics in chronic, refractory patients when possible. Clozapine is largely underutilized, despite continued evidence of its superiority in effectiveness and prevention of relapse³ vs other agents, and has a lower risk of TD. The use of polypharmacy, on the other hand, has continued to display a lack of added benefit in treating symptoms of psychosis, and an increase in adverse effects.⁴

5. Consider pharmacotherapy if TD has already occurred. Psychiatrists have been waiting for pharmacologic options for treating TD for quite some time. Explore using VMAT2 inhibitors and other agents when it is too late to implement prevention or when a patient’s symptoms are refractory to other treatments. However, avoid anticholinergic medications; there is insufficient data to support the use of these agents in the treatment of TD.⁵
