RESUMEN

Smooth muscle cell (SMC) contraction and vascular tone are modulated by phosphorylation and multiple modifications of the thick filament, and thin filament regulation of SMC contraction has been reported to involve extracellular regulated kinase (ERK). Previous studies in ferrets suggest that the actin-binding protein, calponin 1 (CNN1), acts as a scaffold linking protein kinase C (PKC), Raf, MEK and ERK, promoting PKC-dependent ERK activation. To gain further insight into this function of CNN1 in ERK activation and the regulation of SMC contractility in mice, we generated a novel Calponin 1 knockout mouse (Cnn1 KO) by a single base substitution in an intronic CArG box that preferentially abolishes expression of CNN1 in vascular SMCs. Using this new Cnn1 KO mouse, we show that ablation of CNN1 has two effects, depending on the cytosolic free calcium level: (1) in the presence of elevated intracellular calcium caused by agonist stimulation, Cnn1 KO mice display a reduced amplitude of stress and stiffness but an increase in agonist-induced ERK activation; and (2) during intracellular calcium depletion, in the presence of an agonist, Cnn1 KO mice exhibit increased duration of SM tone maintenance. Together, these results suggest that CNN1 plays an important and complex modulatory role in SMC contractile tone amplitude and maintenance.

RESUMEN

As a primary access point for crisis psychiatric care, the emergency department (ED) is uniquely positioned to improve the quality of care and outcomes for patients with psychiatric emergencies. Quality measurement is the first key step in understanding the gaps and variations in emergency psychiatric care to guide quality improvement initiatives. Our objective was to develop a quality measurement framework informed by a comprehensive review and gap analysis of quality measures for ED psychiatric care. We conducted a systematic literature review and convened an expert panel in emergency medicine, psychiatry, and quality improvement to consider if and how existing quality measures evaluate the delivery of emergency psychiatric care in the ED setting. The expert panel reviewed 48 measures, of which 5 were standardized, and 3 had active National Quality Forum endorsement. Drawing from the measure appraisal, we developed a quality measurement framework with specific structural, process, and outcome measures across the ED care continuum. This framework can help shape an emergency medicine roadmap for future clinical quality improvement initiatives, research, and advocacy work designed to improve outcomes for patients presenting with psychiatric emergencies.

RESUMEN

INTRODUCTION: Veterans die by suicide at higher rates than nonveterans. Given that the emergency department is often the first point of entry to healthcare following a suicide attempt, it would be beneficial for community providers to have knowledge of the characteristics, medical issues, and effective treatments most often associated with those having served in the military to ensure guideline concordant and quality suicide care. This study aimed to identify assessment and referral practices of emergency departments at rural community hospitals related to care for suicidal veterans and explore the feasibility and acceptability of identifying veterans in need of postdischarge aftercare. METHODS: This qualitative exploratory study involved content analysis of semistructured interviews. Ten emergency clinicians from 5 rural Arkansas counties with high suicide rates were interviewed about their experiences working with suicidal patients within the emergency department and perceptions of assessment, management, and referral practices. RESULTS: Although most of the emergency departments had a process for assessing for suicide risk, emergency clinicians did not always feel confident in their knowledge of assessing and caring for suicidal patients. Military history was not included in assessment, treatment, or aftercare planning, nor were brief interventions such as safety planning or lethal means safety education provided. DISCUSSION: Best practices for suicide assessment and management of veterans exist; however, challenges specific to the emergency department regarding staff training and engaging the community to effectively link at-risk veterans to needed care hinder implementation. Veteran-inclusive assessment and intervention practices could enhance the quality of care provided in community emergency departments.

RESUMEN

BACKGROUND: Patients with severe agitation are frequently encountered in the emergency department (ED). At times, these patients are physically restrained and given calming medications; however, little is known about the effects of medications and other predictors on restraint duration. OBJECTIVE: Our aim was to compare restraint duration when haloperidol or ziprasidone was used as the primary antipsychotic with or without concomitant medications, and to identify predictors of restraint duration. METHODS: We performed a review of a retrospective cohort of physically restrained ED patients between January 1, 2013 and November 30, 2017. An unadjusted analysis and adjusted linear regression model were used to evaluate the effect of antipsychotic choice on restraint duration, controlling for sex, age, race, homelessness, arrival in restraints, re-restraint during visit, concomitant medications (i.e., benzodiazepines or anticholinergics), additional medications given during restraint, time of day, and patient disposition. RESULTS: In 386 patients (319 haloperidol, 67 ziprasidone), the average restraint duration was 2.4 h (95% confidence interval [CI] 2.2 to 2.6 h). There were no differences in physical restraint times between ziprasidone and haloperidol groups in the unadjusted (mean difference 0.12 h; 95% CI -0.42 to 0.66 h) or adjusted analyses (-12.7%; 95% CI -33.9% to 8.6%). Haloperidol given with diphenhydramine alone was associated with decreased restraint duration (-30.8%; 95% CI -50.6% to -11.1%) The largest association with restraint duration was administration of additional sedating medications during restraint, prolonging restraint by 62% (95% CI 27.1% to 96.9%). In addition, compared with White patients, Black patients spent significantly more time restrained (mean difference 33.9%; 95% CI 9.0% to 58.9%). CONCLUSIONS: Restraint duration of agitated ED patients was similar when haloperidol or ziprasidone was used as the primary antipsychotic. However, race and additional medications given during restraint were significantly associated with restraint duration.

RESUMEN

Behavioral crises continue to escalate across the United States. Our country has one of the highest suicide rates amongst developed nations. More than 45,000 U.S. citizens are dying annually now from suicide. Many with suicidal ideation seek care in Emergency Departments in hospital systems under resourced to handle this growing public health crisis. Evidenced-based screening, risk stratification, and treatment continues to evolve and is not standardized. Improved suicide education needs to be more broadly applied across healthcare and society. Missouri as a state is making concentrated efforts to improve resources and care for those with suicidal ideation. Many challenges need to be overcome and time will tell if new statewide initiatives will reduce Missouri's high rate of suicide.

RESUMEN

The coronavirus disease 2019 (COVID-19) pandemic has been associated with a declining volume of patients seen in the emergency department. Despite the need for seeking urgent care for conditions such as myocardial infarction, many people may not seek treatment. This study seeks to measure associations between the COVID-19 pandemic and location of death among individuals who died from ischemic heart disease (IHD). Data obtained from death certificates from the Arkansas Department of Health was used to conduct a difference-in-difference analysis to assess whether decedents of IHD were more likely to die at home during the pandemic (March 2020 through September 2020). The analysis compared location of death for decedents of IHD pre and during the pandemic to location of death for decedents from non-natural causes. Before the pandemic, 50.0% of decedents of IHD died at home compared to 57.9% dying at home during (through September 2020) the pandemic study period (p < .001). There was no difference in the proportion of decedents who died at home from non-natural causes before and during the pandemic study period (55.8% vs. 53.5%; p = .21). After controlling for confounders, there was a 48% increase in the odds of dying at home from IHD during the pandemic study period (p < .001) relative to the change in dying at home due to non-natural causes. During the study period, there was an increase in the proportion of decedents who died at home due to IHD. Despite the ongoing pandemic, practitioners should emphasize the need to seek urgent care during an emergency.

RESUMEN

The treatment of opioid use disorder with buprenorphine and methadone reduces morbidity and mortality in patients with opioid use disorder. The initiation of buprenorphine in the emergency department (ED) has been associated with increased rates of outpatient treatment linkage and decreased drug use when compared to patients randomized to receive standard ED referral. As such, the ED has been increasingly recognized as a venue for the identification and initiation of treatment for opioid use disorder, but no formal American College of Emergency Physicians (ACEP) recommendations on the topic have previously been published. The ACEP convened a group of emergency physicians with expertise in clinical research, addiction, toxicology, and administration to review literature and develop consensus recommendations on the treatment of opioid use disorder in the ED. Based on literature review, clinical experience, and expert consensus, the group recommends that emergency physicians offer to initiate opioid use disorder treatment with buprenorphine in appropriate patients and provide direct linkage to ongoing treatment for patients with untreated opioid use disorder. These consensus recommendations include strategies for opioid use disorder treatment initiation and ED program implementation. They were approved by the ACEP board of directors in January 2021.

RESUMEN

BACKGROUND: Severely agitated patients in the emergency department (ED) are often sedated with intramuscularly-administered medications. The evidence base underlying particular medication choices is surprisingly sparse, as existing reviews either have methodological limitations or have included data collected outside of emergent settings. OBJECTIVES: The objective of this review was to examine all controlled trials in emergent settings that have used standardized scales to measure the effectiveness of intramuscular medication for the treatment of acute agitation. METHODS: This review was registered in Prospero as CRD42018105745. PubMed, International Pharmaceutical Abstracts, Web of Science, PsycINFO, and clinicaltrials.gov were searched for prospective controlled trials investigating intramuscular antipsychotics for agitation. Articles were assessed for bias across five domains using the revised Cochrane Risk of Bias Tool. RESULTS: Eight studies were eligible for inclusion in the systematic review, none of which had a low risk of bias. Five studies had a moderate risk of bias with heterogenous designs, populations, and treatments. These studies seemed to suggest that second generation antipsychotics (SGAs) likely reduce agitation as effectively as first generation antipsychotics (FGAs) plus an adjunctive medication with similar or lower risk of side effects. CONCLUSIONS: Existing trials on the use of intramuscular antipsychotics in the ED/psychiatric ED setting were small, heterogenous, and at a moderate or high risk of bias. Given the clinical importance of this topic, further prospective investigations are desperately needed but are currently unfeasible under Food and Drug Administration Exception From Informed Consent regulations.

RESUMEN

OBJECTIVES: Suicide rates in the United States rose 35.2% from 1999-2018. As emergency department (ED) providers often have limited training in management of suicidal patients and minimal access to mental health experts, clinical practice guidelines (CPGs) may improve care for these patients. However, clinical practice guidelines that do not adhere to quality standards for development may be harmful both to patients, if they promote practices based on flawed evidence, and to ED providers, if used in malpractice claims. In 2011, the Institute of Medicine created standards to determine the trustworthiness of CPGs. This review assessed the adherence of suicide prevention CPGs, intended for the ED, to these standards. Secondary objectives were to assess the association of adherence both with first author/organization specialty (ED vs non-ED) and with inclusion of recommendations on substance use, a potent risk factor for suicide. METHODS: This is a systematic review of available suicide-prevention CPGs for the ED in both peer-reviewed and gray literature. This review followed the PRISMA standards for reporting systematic reviews. RESULTS: Of 22 included CPGs, the 7 ED-sponsored CPGs had higher adherence to quality standards (3.1 vs 2.4) and included the highest-rated CPG (ICAR2E) identified by this review. Regardless of specialty, nearly all CPGs included some mention of identifying or managing substance use. CONCLUSIONS: Most suicide prevention CPGs intended for the ED are written by non-ED first authors or organizations and have low adherence to quality standards. Future CPGs should be developed with more scientific rigor, include a multidisciplinary writing group, and be created by authors working in the practice environment to which the CPG applies.

RESUMEN

Agitation and delirium are common reasons for older adults to seek care in the emergency department (ED). Providing care for this population in the ED setting can be challenging for emergency physicians. There are several knowledge translation gaps in how to best screen older adults for these conditions and how to manage them. A working group of subject-matter experts convened to develop an easy-to-use, point-of-care tool to assist emergency physicians in the care of these patients. The tool is designed to serve as a resource to address the knowledge translation and implementation gaps that exist in the field. The purpose of this article is present and explain the Assess, Diagnose, Evaluate, Prevent, and Treat tool. Participants were identified with expertise in emergency medicine, geriatric emergency medicine, geriatrics, and psychiatry. Background literature reviews were performed before the in-person meeting in key areas: delirium, dementia, and agitation in older adults. Participants worked electronically before and after an in-person meeting to finalize development of the tool in 2017. Subsequent work was performed electronically in the following months and additional expert review sought. EDs are an important point of care for older adults. Behavioral changes in older adults can be a manifestation of underlying medical problems, mental health concerns, medication adverse effects, substance abuse, or dementia. Five core principles were identified by the group that can help ensure adequate and thorough care for older adults with agitation or delirium: assess, diagnose, evaluate, prevent, and treat. This article provides background for and explains the importance of these principles related to the care of older adults with agitation. It is important for emergency physicians to recognize the spectrum of underlying causes of behavioral changes and have the tools to screen older adults for those causes, and methods to treat the underlying causes and ameliorate their symptoms.

RESUMEN

INTRODUCTION: Caring for suicidal patients can be challenging, especially in emergency departments without easy access to mental health specialists. The American College of Emergency Physicians and the American Foundation for Suicide Prevention appointed a working group to create an easy-to-use suicide prevention tool for ED providers. METHODS: The writing group created an easy-to-use mnemonic for the care of adult patients as a way of organizing sequential steps, accompanied by a systematic review of available ED-based suicide prevention literature. The systematic review was performed both to ensure that all relevant evidence was taken into account as well as to evaluate the strength of evidence for each recommendation. Levels of evidence were assigned utilizing the ACEP level of evidence classification. RESULTS: The writing group created the mnemonic ICAR2E, which stands for Identify suicide risk; Communicate; Assess for life threats and ensure safety; Risk assessment (of suicide); Reduce the risk (of suicide); and Extend care beyond the ED. 31 articles were identified in the search, and were included in the systematic review. CONCLUSIONS: The ICAR2E mnemonic may be a feasible way for practicing ED clinicians to provide evidence-based care to suicidal patients. However, further research is needed.

RESUMEN

BACKGROUND: Involuntary mental health detainments should only be utilized when less restrictive alternatives are unavailable and should be discontinued as soon as safety can be ensured. The study objective was to determine if child and adolescent psychiatrists discontinue a greater proportion of involuntary holds than general psychiatrists for similar pediatric patients. METHODS: Retrospective analysis of consecutive patients under 18 years placed on an involuntary hold in the prehospital setting presenting over a 1-year period to one high-volume emergency department (ED) where youth on involuntary holds are seen by child and adolescent psychiatrists when available and general psychiatrists otherwise. The primary outcome of interest was hold discontinuation after initial psychiatric consultation. The key predictor of interest was psychiatrist specialty (child and adolescent vs. general). We conducted multivariate logistic regression modeling adjusting for patient characteristics and time of arrival. RESULTS: Child and adolescent psychiatrists discontinued 27.4% (51/186) of prehospital holds while general psychiatrists discontinued only 10.6% (22/207). After adjusting for observable confounders, holds were over 3 times as likely to be discontinued in patients evaluated by child and adolescent psychiatrists rather than general emergency psychiatrists (adjusted OR 3.2, 95% CI 1.7-5.9, p < 0.001). CONCLUSIONS: Child and adolescent psychiatrists are much more likely to discontinue prehospital involuntary mental health holds compared with general emergency psychiatrists. While inappropriate hold discontinuation places patients at risk of harm, prolonged hold continuation limits patients' rights and potentially increases psychiatric boarding in EDs. Earlier access to child and adolescent psychiatry may facilitate early hold discontinuation and standardize patient care.

RESUMEN

BACKGROUND: The most recent guidelines on prescribing opioids from the United States Centers for Disease Control recommend that clinicians not prescribe opioids as first-line therapy for chronic non-cancer pain. If an opioid prescription is considered for a patient already on opioids, prescribers are encouraged to check the statewide prescription drug monitoring database (PDMP). Some additional guidelines recommend screening tools such as the Current Opioid Misuse Measure (COMM) which may also help identify drug-aberrant behaviors. OBJECTIVE: To compare the PDMP and the Current Opioid Misuse Measure (COMM), a commonly-recommended screening tool for patients on opioids, in detecting drug-aberrant behaviors in patients already taking opioids at the time of ED presentation. METHODS: Patients on opioids were enrolled prospectively in a mixed urban-suburban ED seeing approximately 65,000 patients per year. The sensitivity, specificity, likelihood ratios, and diagnostic odds ratios of the PDMP and COMM were compared against objective criteria of drug-aberrant behaviors as documented in the electronic medical record (EMR) and medical examiner databases. RESULTS: Compared to the COMM, the PDMP had similar sensitivity (36% vs 45%) and similar specificity (79% vs 55%), but better positive predictive value, better negative predictive value, and better diagnostic odds ratio. The combination of the PDMP and the COMM did not improve the detection of drug-aberrant behaviors. CONCLUSIONS: The PDMP alone is a more useful as a screening instrument than either the COMM or the combination of the PDMP plus COMM in patients already taking opioids at time of ED presentation. However, the PDMP misses a majority of patients with documented drug-aberrant behaviors in the EMR, and should not be used in isolation to justify whether a particular opioid prescription is appropriate.

RESUMEN

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a congenital visceral myopathy characterized by severe dilation of the urinary bladder and defective intestinal motility. The genetic basis of MMIHS has been ascribed to spontaneous and autosomal dominant mutations in actin gamma 2 (ACTG2), a smooth muscle contractile gene. However, evidence suggesting a recessive origin of the disease also exists. Using combined homozygosity mapping and whole exome sequencing, a genetically isolated family was found to carry a premature termination codon in Leiomodin1 (LMOD1), a gene preferentially expressed in vascular and visceral smooth muscle cells. Parents heterozygous for the mutation exhibited no abnormalities, but a child homozygous for the premature termination codon displayed symptoms consistent with MMIHS. We used CRISPR-Cas9 (CRISPR-associated protein) genome editing of Lmod1 to generate a similar premature termination codon. Mice homozygous for the mutation showed loss of LMOD1 protein and pathology consistent with MMIHS, including late gestation expansion of the bladder, hydronephrosis, and rapid demise after parturition. Loss of LMOD1 resulted in a reduction of filamentous actin, elongated cytoskeletal dense bodies, and impaired intestinal smooth muscle contractility. These results define LMOD1 as a disease gene for MMIHS and suggest its role in establishing normal smooth muscle cytoskeletal-contractile coupling.

RESUMEN

BACKGROUND: Organic conditions can often mimic neuropsychiatric disorders, leading to delays in diagnosis and treatment for the most vulnerable populations presenting to the emergency department (ED). CASE REPORT: Here we discuss a case of cryptococcal meningoencephalitis seemingly consistent with psychosis on initial evaluation, and present strategies to recognize and treat this condition. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Due to the indolent time course of this disease, initial symptoms of altered mental status and personality changes may be attributed to drug use or psychiatric illness before more overt evidence for increased intracranial pressure and neurologic infection develops. It is important for emergency clinicians to maintain a high level of suspicion for this condition in at-risk patients and reassess them frequently during their ED visit.

RESUMEN

BACKGROUND: Currently, no universally accepted methods exist to assess drug-related aberrant behaviors in emergency department (ED) patients. There are several screening tools to identify opioid misuse in patients with chronic pain, however, the validity of these screening tools to assess for misuse within the ED remains unclear. OBJECTIVES: This study investigated the effectiveness of three commonly used screening tools, previously validated in outpatient pain management settings, to assess risk of opioid misuse in ED patients. METHODS: This was a prospective observational study of 154 participants (median age 50 years; 49.6% female) presenting to an academic ED for a chief complaint of pain ≥ 6 months or an opioid refill request. Participants completed the Opioid Risk Tool, the Screener and Opioid Assessment for Patients with Pain-Revised, and the Current Opioid Misuse Measure. Scores for each were compared with electronic medical record (EMR) data alone or a reference standard comprising EMR + statewide prescription drug monitoring program (PDMP) + medical examiner database. RESULTS: Using the combined reference standard, 55.8% of participants displayed at least one aberrant behavior. Regardless of the reference standard, the test characteristics of these screening tools were modest at best, with likelihood ratios close to 1. CONCLUSION: Three screening tools previously validated in outpatient pain management settings poorly categorized risk among ED patients with chronic noncancer pain or requests for opioid refills, and should not be used to assess drug-aberrant behaviors in the ED. Review of the EMR alone or together with the PDMP may be more useful methods to assess drug-aberrant behaviors in the ED setting.

RESUMEN

BACKGROUND: Suicide screening scales have been advocated for use in the ED setting. However, it is currently unknown whether patients classified as low-risk on these scales can be safely discharged from the emergency department. This study evaluated the utility of three commonly-used suicide screening tools in the emergency department to predict ED disposition, with special interest in discharge among low-risk patients. METHODS: This prospective observational study enrolled a convenience sample of patients who answered "yes" to a triage suicidal ideation question in an urban academic emergency department. Patients were administered the weighted modified SADPERSONS Scale, Suicide Assessment Five-step Evaluation and Triage, and Columbia-Suicide Severity Rating Scale. Patients who subsequently received a psychiatric evaluation were included, and the utility of these screening tools to predict disposition was evaluated. RESULTS: 276 subjects completed all three suicide screening tools and were included in data analyses. Eighty-two patients (30%) were admitted or transferred. Three patients (1%) died by suicide within one year of enrollment; one was hospitalized at the end of his or her enrollment visit, dying by suicide seven months later and the other two were discharged, dying by suicide nine and ten months later, respectively. The screening tools exhibited modest negative predictive values (range: 0.66-0.73). CONCLUSION: Three suicide screening tools displayed modest ability to predict the disposition of patients who presented to an emergency department with suicidal ideation. This study supports the current ACEP clinical policy on psychiatric patients which states that screening tools should not be used in isolation to guide disposition decisions of suicidal patients from the ED.

RESUMEN

BACKGROUND: Novel means of emergency department (ED) post-discharge communication-telephone callbacks and text messages-are increasingly being utilized to facilitate patient-oriented outcomes, such as ED revisits, patient adherence, and satisfaction. OBJECTIVE: The primary measure of interest is the rate of ED revisits in the week after discharge. The secondary measures of interests are rate of primary medical doctor (PMD) or specialist physician contact in the week after discharge and patient satisfaction. METHODS: Pilot randomized controlled trial with three groups: usual discharge; usual care + phone call 48 h after discharge asking if patients wanted to speak with a physician; or usual care + text message 48 h after discharge asking if patients wanted to speak with a physician. All participants received a 1-week assessment of patient satisfaction. ED revisit and contact with PMD or specialist physician within 7 days of discharge were obtained from electronic medical record and analyzed using χ2 test. RESULTS: Two hundred and fifty-one patients were enrolled and randomized (66 control, 103 phone, 82 text). Although the three groups did not show a statistically significant difference, the phone and text groups had similar and lower proportions of patients revisiting the ED (>50% reduction) and calling or visiting their PMD or specialist physician (approximately 30% reduction) than the control group (χ2 = 4.57, degrees of freedom [df] = 2, p = 0.10; χ2 = 1.36, df = 2, p = 0.51). There was no difference in patient satisfaction (χ2 = 2.88, df = 2, p = 0.24). CONCLUSIONS: Patients who are contacted for ED follow-up by phone and text, though perhaps not more satisfied, may tend to revisit the ED and contact their PMD or specialty physician less often than patients receiving standard written discharge instructions. However, this pilot study is underpowered, so larger randomized studies are needed to confirm.

RESUMEN

BACKGROUND: Patients presenting to the emergency department (ED) with psychiatric complaints often require medical screening to evaluate for a medical cause of their symptoms. OBJECTIVE: We sought to evaluate the existing literature on the medical screening of psychiatric patients and establish recommendations for ideal screening practices in Western-style EDs. METHODS: PubMed, PsycINFO, and ClinicalTrials.gov were searched for clinical studies examining the medical screening of adult psychiatric patients in the ED or inappropriate referrals to psychiatry. Articles were graded using the Effective Public Health Practice Project (EPHPP) grading tool and sorted into topics. A 3-level grading algorithm used by other emergency medicine organizations was used to evaluate the strength of the evidence for each recommendation. RESULTS: Sixty articles met the inclusion and exclusion criteria. Most published literature on medical screening consisted of nonrandomized studies with a high risk of bias. Some screening procedures, such as history and physical examination, were extensively recommended. Other screening procedures received mixed recommendations. CONCLUSIONS: Based on available literature, physician experts developed 7 recommendations. For a patient with known psychiatric disease presenting with symptom exacerbation, medical screening should include a full medical and psychiatric history, a targeted physical examination, and a mental status examination. Urine toxicology screening and nonurine drug screen laboratory testing should not be routinely performed. Additional screening tests may be valuable for patients with new-onset psychiatric symptoms who are ≥65 years of age, are immunosuppressed, or have concomitant medical disease. However, additional studies on this topic with more rigorous methodology must be conducted to establish definitive guidelines.

RESUMEN

BACKGROUND: Understanding more about the efficacy and safety of oral second-generation antipsychotic medications in reducing the symptoms of acute agitation could improve the treatment of psychiatric emergencies. OBJECTIVE: The objective of this scoping review was to examine the evidence base underlying expert consensus panel recommendations for the use of oral second-generation antipsychotics to treat acute agitation in mentally ill patients. METHODS: The Cochrane Schizophrenia Group's Study-Based Register was searched for randomized controlled trials comparing oral second-generation antipsychotics, benzodiazepines, or first-generation antipsychotics with or without adjunctive benzodiazepines, irrespective of route of administration of the drug being compared. Six articles were included in the final review. RESULTS: Two oral second-generation antipsychotic medications were studied across the six included trials. While the studies had relatively small sample sizes, oral second-generation antipsychotics were similarly effective to intramuscular first-generation antipsychotics in treating symptoms of acute agitation and had similar side-effect profiles. CONCLUSIONS: This scoping review identified six randomized trials investigating the use of oral second-generation antipsychotic medications in the reduction of acute agitation among patients experiencing psychiatric emergencies. Further research will be necessary to make clinical recommendations due to the overall dearth of randomized trials, as well as the small sample sizes of the included studies.
