State of Acute Agitation at Psychiatric Emergencies in Europe: The STAGE Study

Physical restraint within the prehospital Emergency Medical Care Environment: A scoping review

Background

Psychomotor agitation and aggressive behaviour (AAB) have the potential to occur in any healthcare setting, including those in which Emergency Medical Services (EMS) operate. This scoping review aimed to examine the available literature on physical restraint of patients within the prehospital setting and to identify guidelines and their effectiveness, safety to patients and health care practitioners and strategies relating to physical restraint when used by EMS.

Methods

We performed our scoping review using the methodological framework described by Arksey and O'Malley augmented by that of Sucharew and Macaluso. Several steps guided the review process: identification of the research question, eligibility criteria, information sources (CINAHL, Medline, Cochrane and Scopus), search, selection and data collection, ethical approval, collation, summarizing and reporting on the results.

Results

The population of interest, in this scoping review was prehospital physically restrained patients, however, there was a reduced research focus on this population in comparison to the larger emergency department.

Conclusion

The limitation of informed consent from incapacitated patients may relate to the lack of prospective real-world research from previous and future studies. Future research should focus on patient management, adverse events, practitioner risk, policy, and education within the prehospital setting.

NANDA nursing diagnoses associated with the occurrence of psychomotor agitation in patients with severe mental disorder: a cross-sectional study

BACKGROUND

Psychomotor agitation is increased psychomotor activity, restlessness and irritability. People with psychomotor agitation respond by overreacting to intrinsic and extrinsic stimuli, experiencing stress and/or cognitive impairment. the aim was to analyse the association of nursing diagnoses with the disinhibition dimension, the aggressiveness dimension and the lability dimension of the Corrigan Agitated Behaviour Scale.

METHODS

This study was conducted in Spain using a multicentre cross-sectional convenience sample of 140 patients who had been admitted to psychiatric hospital units and had presented an episode of psychomotor agitation between 2018 and 2021.

RESULTS

The Corrigan Agitated Behaviour Scale was used to assess psychomotor agitation. Associated nursing diagnoses, violence directed at professionals and the environment are shown to be predictive values for the severity of the agitation episode. Moderate-severe psychomotor agitation episodes are shown as predictors of violence directed mainly at professionals and the environment.

CONCLUSIONS

There is an urgent need for mental health nurses to have knowledge of the extended clinic in order to care for users and improve their health conditions in dealing with people, with their social, subjective and biological dimension.

The safety and efficacy of sequential intramuscular/oral ziprasidone treatment of acute episode in patients with schizophrenia: a multicenter, open-labeled study

BACKGROUND

Ziprasidone mesylate injection is an atypical antipsychotic drug which is recently approved in China. In combination with its oral formulation, sequential therapy with ziprasidone brings new interventions to patients with agitation in the acute phase of schizophrenia. The purpose of this 7-day multicenter study conducted in China was to evaluate the efficacy and safety of ziprasidone sequential treatment through intramuscular/oral routes in agitated patients with schizophrenia.

METHODS

A total of 95 patients were enrolled from three centers in this study. The study duration was 7 days. In the first 3 days, subjects were administered an intramuscular injection of ziprasidone 10-40 mg daily and started sequentially with oral ziprasidone 40-80 mg at dinner (or lunch) from the day of the last intramuscular injection. In the following 4 days, according to the severity of the symptoms and the drug response, 120-160 mg of ziprasidone was orally administered daily. In total, six visits were scheduled to assess the Positive and Negative Syndrome Scale (PANSS), the Behavioral Activity Rating Scale (BARS), the Clinical Global Impression of Severity (CGI-S), and Improvement (CGI-I) scores throughout the procedure. Lastly, adverse events were recorded during treatment.

RESULTS

Out of the 95 patients that were enrolled, 83 cases were effectively completed. Visits 3, 4, 6, PANSS, and PANSS-excited component (PANSS-EC) subscale points, and Visit 2-Visit 6 viewpoints, BARS scale points, and baseline scores denote a progressive downward trend (P < 0.001). In this study, 62 adverse events were reported. The most common adverse events were extrapyramidal symptoms (EPS) (23 cases) and excessive sedation(10 cases), and 13 cases of prolonged QTc interval were reported.

CONCLUSIONS

Ziprasidone IM demonstrated significant and rapid reduction in agitation, and sequential oral formulation keep stability and continuation of the treatment can further ensure efficacy. Ziprasidone sequential therapy may provide a new approach to acute agitation in schizophrenic patients.

Sublingual dexmedetomidine: repurposing an anesthetic as an anti-agitation agent

INTRODUCTION

Especially when acutely ill, individuals with schizophrenia and bipolar disorder can present with agitated behavior. The initial approach to agitation management are non-pharmacologic strategies such as verbal de-escalation techniques; however, pharmacologic interventions may be needed. Dexmedetomidine is a selective alpha-2 adrenergic receptor agonist, and a sublingual formulation has been approved in the US for the treatment of agitation associated with schizophrenia and bipolar disorder in adults.

AREAS COVERED

The authors review the published literature on sublingual dexmedetomidine using the US National Library of Medicine's PubMed.gov resource. Pharmacodynamics, pharmacokinetics, and efficacy and tolerability findings are summarized. The authors also provide a discussion to its potential place in the treatment armamentarium.

EXPERT OPINION

Sublingual dexmedetomidine is an effective and well-tolerated pharmacologic option for the treatment of agitation associated with schizophrenia and bipolar disorder. The sublingual method of administration allows for a rapid onset of action with treatment effects beginning as early as 20 minutes after administration. Adverse effects include somnolence, hypotension, oral paresthesia, hypoesthesia, and dry mouth. Further study will be needed to evaluate sublingual dexmedetomidine in real-world patients receiving concomitant psychotropic medications.

Clinical and Sociodemographic Profile of Psychomotor Agitation in Mental Health Hospitalisation: A Multicentre Study

Psychomotor agitation is characterised by an increase in psychomotor activity, restlessness and irritability. People with psychomotor agitation respond by over-reacting to both intrinsic and extrinsic stimuli, experiencing stress and/or altered cognition. The objective of this study is to assess the clinical and sociodemographic profile of psychomotor agitation in patients with severe mental disorders. The study was carried out in Spain by means of multicentre cross-sectional convenience sampling involving 140 patients who had been admitted to psychiatric hospital units and had experienced an episode of psychomotor agitation between 2018 and 2021.Corrigan's Agitated Behaviour Scale was used to assess psychomotor agitation. The results show that the predominant characteristic in psychomotor agitation is aggressiveness, which is also the most reported factor in patients with severe mental disorder. Patients who also have anxiety develop psychomotor agitation symptoms of moderate/severe intensity. The clinical and sociodemographic profile found in our study is consistent with other studies on the prevalence of psychomotor agitation.

Inhaled Loxapine as a Rapid Treatment for Agitation in Patients with Personality Disorder: A Prospective Study on the Effects of Time

Objective

Agitation in patients diagnosed with personality disorders (PD) is one of the most frequent crises in emergency departments (ED). Although many medications have been tested, their effectiveness has been small or non-significant, and no specific drugs are supported by the available evidence. This study aimed to evaluate the efficacy of Inhaled loxapine (IL) as a therapeutic option for agitated patients with PD.

Methods

A naturalistic, unicentric, prospective study was carried out. Thirty subjects diagnosed with PD and attending the ED with episodes of agitation were recruited most of whom were women diagnosed with Borderline Personality Disorder. Subjects were treated with a single dose of IL (9.1 mg). Efficacy was assessed with the Clinical Global Impression scale, the Excited Component of the Positive and Negative Syndrome Scale (PANSS-EC) and the Agitation-Calmness Evaluation Scale (ACES). Patients were followed 60 minutes after administration to measure IL effect and its duration.

Results

IL exhibited an overall efficacy in managing mild to severe agitation, with a quick onset of effect and persistence. ‘Effect of time’, where IL efficacy is maintained over time, is more marked in higher-severity agitation. No additional treatments were needed to improve agitation during the follow-up time.

Conclusion

Results suggest that IL could be a safe and effective option to manage agitation in PD.

Experience of mental health nurses regarding mechanical restraint in patients with psychomotor agitation: A qualitative study

AIM

To explore mental health nurses' experiences whilst managing a patient with psychomotor agitation, and the factors that influence the decision to use mechanical restraints.

BACKGROUND

Psychomotor agitation is considered a potentially violent psychiatric emergency. The management of disruptive behaviours includes mechanical restraints as the last resort although its use has consequences for patients, professionals and the therapeutic relationship.

DESIGN

A qualitative study design with a hermeneutical approach was developed.

METHODS

A total of 31 nurses were purposively sampled from six short- and medium-stay mental health inpatient units. Data were obtained from semi-structured interviews. A thematic content analysis following the seven steps of Colaizzi's method was performed. Three researchers independently conducted an inductive analysis within a perspective of a hermeneutic paradigm. The COREQ checklist was followed in carrying out this research.

RESULTS

Four themes emerged from the analysis: 1) Nurses' perceptions of restraint methods, 2) Factors influencing decision-making, 3) Consequences for professionals of the use of mechanical restraint and 4) Alternatives to mechanical restraint.

CONCLUSIONS

Aspects such as the importance of teamwork, the issue of cognitive dissonance, ethical conflict and barriers to effecting the withdrawal of these measures affect the mental health nurse's decision-making process. The understanding of these aspects is crucial to further reducing its incidence and negative consequences and achieving the elimination of mechanical restraints.

RELEVANCE FOR CLINICAL PRACTICE

Knowing how nurses feel during the patient's episode of psychomotor agitation and which factors influence the decision on whether to apply coercive methods can guide us on the quality of care offered.

Fifty years of experience with loxapine for the rapid non-coercive tranquilization of acute behavioral disturbances in schizophrenia patients, and beyond

INTRODUCTION

Acute behavioral disturbances in psychosis, including agitation, comprise a heterogeneous group of manifestations varying in intensity and duration they last for. They require rapid, non-coercive treatments ranging from verbal de-escalation to the calming effect of pharmacological agents. The treatment goals are reduction of patient suffering and prevention of disease deterioration. Stabilizing rather than sedating is preferred to ensure improved compliance and a stronger therapeutic alliance. Furthermore, animal pharmacology and clinical studies on agitation reveal the robust calming and anxiolytic properties of loxapine.

AREAS COVERED

This review covers the pharmacological and clinical history of loxapine along with research developments. It emphasizes the advantages of its multiple formulations ranging from injectable forms and tablets to orally inhaled forms to attain rapid and fine-tuned tranquilization.

EXPERT OPINION

Rapid tranquillization is achieved within 2-6 hours using liquid orally-consumed loxapine, and within an hour or less with its IM or orally inhaled forms. Loxapine has been adopted in the management of a wide range of acute disturbances, such as agitation in psychosis. In the context of personalized medicine, key cellular and molecular elements of the schizophrenia phenotype were recently shown to be improved with loxapine.

Translation, cross-cultural adaptation, and validation of the Behavioral Activity Rating Scale (BARS) for the Brazilian population

INTRODUCTION

Few instruments are available in Brazil to evaluate psychomotor activity in psychiatric emergency, clinical, and research settings. This study aimed to perform a cross-cultural adaptation of the Behavioral Activity Rating Scale (BARS) into Brazilian Portuguese and assess the adapted scale's psychometric properties.

METHOD

An expert consensus committee conducted a translation and back-translation of the original scale, resulting in the BARS-BR. Four pairs of physicians administered the BARS-BR and the Sedation-Agitation Scale (SAS) to patients in a hospital psychiatry emergency room and patients in the hospital's psychiatric wards. The BARS-BR was compared to the SAS to assess concurrent validity and internal consistency was evaluated with the Bland-Altman technique.

RESULTS

In the emergency room, the correlation coefficients between the first and second assessments were rho = 0.997 and rho = 1.0, respectively. In the hospital wards, the correlation coefficient between the pair of evaluators was rho = 0.951. There were strong correlations between the BARS-BR score of the first examiner and the SAS score of the second examiner (rho = 0.903) and between the SAS score of the first examiner and the BARS-BR score of the second examiner (rho = 0.893).

CONCLUSION

The BARS-BR showed good psychometric properties, and we recommend its use because it constitutes an easy method for assessment of changes in psychomotor activity. Further studies are suggested to evaluate adoption and comprehension of the BARS-BR scale by all classes of healthcare professionals.

The Management of Psychomotor Agitation Associated with Schizophrenia or Bipolar Disorder: A Brief Review

The early and correct assessment of psychomotor agitation (PMA) is essential to ensure prompt intervention by healthcare professionals to improve the patient’s condition, protect healthcare staff, and facilitate future management. Proper training for recognizing and managing agitation in all care settings is desirable to improve patient outcomes. The best approach is one that is ethical, non-invasive, and respectful of the patient’s dignity. When deemed necessary, pharmacological interventions must be administered rapidly and avoid producing an excessive state of sedation, except in cases of severe and imminent danger to the patient or others. The purpose of this brief review is to raise awareness about best practices for the management of PMA in emergency care situations and consider the role of new pharmacological interventions in patients with agitation associated with bipolar disorder or schizophrenia.

Distribution of agitation and related symptoms among hospitalized patients using a scalable natural language processing method

BACKGROUND

Agitation is a common feature of many neuropsychiatric disorders.

OBJECTIVE

Understanding the prevalence, implications, and characteristics of agitation among hospitalized populations can facilitate more precise recognition of disability arising from neuropsychiatric diseases.

METHODS

We developed two agitation phenotypes using an expansion of expert curated term lists. These phenotypes were used to characterize five years of psychiatric admissions. The relationship of agitation symptoms and length of stay was examined.

RESULTS

Among 4548 psychiatric admissions, 1134 (24.9%) included documentation of agitation based on the primary agitation phenotype. These symptoms were greater among individuals with public insurance, and those with mania and psychosis compared to major depressive disorder. Greater symptoms were associated with longer hospital stay, with ~0.9 day increase in stay for every 10% increase in agitation phenotype.

CONCLUSION

Agitation was common at hospital admission and associated with diagnosis and longer length of stay. Characterizing agitation-related symptoms through natural language processing may provide new tools for understanding agitated behaviors and their relationship to delirium.

Associations of C-Reactive Protein, Free Triiodothyronine, Thyroid Stimulating Hormone and Creatinine Levels with Agitation in Patients with Schizophrenia: A Comparative Cross-Sectional Study

PURPOSE

Agitation is prevalent among inpatients with schizophrenia. The aim of this study was to investigate whether biochemical parameters are associated with agitation in schizophrenia.

PATIENTS AND METHODS

Agitation was evaluated by the Positive and Negative Syndrome Scale-Excited Component questionnaire (PANSS-EC). Fasting serum levels of C-reactive protein (CRP), free triiodothyronine (FT3), free thyroxine (FT4), thyroid-stimulating hormone (TSH), uric acid (UA), creatinine, glucose and lipids were measured.

RESULTS

The analysis included 154 inpatients with schizophrenia (71 with agitation, 83 without agitation) and 75 healthy control subjects. Patients with schizophrenia and agitation had higher serum levels of CRP, FT3, FT4 and UA as well as lower levels of serum TSH and creatinine than patients without agitation (all P < 0.05). Multivariate logistic regression analysis indicated that serum CRP (odds ratio [OR] = 1.470, P = 0.001), FT3 (OR = 13.026, P < 0.001), TSH (OR = 0.758, P = 0.033) and creatinine (OR = 0.965, P = 0.004) were significantly associated with agitation in schizophrenia. CRP, FT3, TSH and creatinine achieved an area under the ROC curve of 0.626, 0.728, 0.620 and 0.663 respectively in discriminating schizophrenia with or without agitation.

CONCLUSION

Increased serum CRP and FT3 levels and decreased serum TSH and creatinine levels are independent risk factors for agitation in hospitalized patients with schizophrenia. Inflammation, thyroid hormones and renal function may be involved in the pathogenesis of agitation in schizophrenia.

Recognition and management of agitation in acute mental health services: a qualitative evaluation of staff perceptions

BACKGROUND

Agitation among patients is a common and distressing behaviour across a variety of health care settings, particularly inpatient mental health. Unless recognised early and effectively managed it can lead to aggression and personal injury. The aim of this paper is to explore the experiences of mental health nurses in recognising and managing agitation in an inpatient mental health setting and the alignment of these experiences with best practice and person-centred care.

METHODS

This study used a descriptive qualitative methodology. Semi-structured focus group interviews were conducted with 20 nurses working in a mental health unit in 2018. Nursing staff described their experiences of assessing and managing agitation. Descriptive and Thematic Analysis were undertaken of the transcribed focus group dialogue.

RESULTS

Nurses combined their clinical knowledge, assessment protocols and training with information from patients to make an individualised assessment of agitation. Nurses also adopted an individualised approach to management by engaging patients in decisions about their care. In keeping with best practice recommendations, de-escalation strategies were the first choice option for management, though nurses also described using both coercive restraint and medication under certain circumstances. From the perspective of patient-centred care, the care provided aligned with elements of person-centred care nursing care.

CONCLUSION

The findings suggest that clinical mental health nurses assess and manage agitation, with certain exceptions, in line with best practice and a person-centred care nursing framework.

Alternatives to the Use of Mechanical Restraints in the Management of Agitation or Aggressions of Psychiatric Patients: A Scoping Review

Coercive measures are a highly controversial issue in mental health. Although scientific evidence on their impact is limited, they are frequently used. Furthermore, they lead to a high number of ethical, legal, and clinical repercussions on both patients, and professionals and institutions. This review aims to assess the impact of the main alternative measures to prevent or limit the use of coercive measures with restraints in the management of agitated psychiatric patients. The research was conducted following the guidelines recommended by PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) in Medline, Cochrane Library, CINAHL, Web of Science, PsycInfo, LILACS, and Health Database of records between 2015 and 2020. After a critical reading, 21 valid articles were included. Both simple interventions and complex restraint programs were evaluated. Training in de-escalation techniques, risk assessment, and implementation of the “six core strategies” or “Safewards” program were the most assessed and effective interventions to reduce aggressive behaviors and the use of coercive measures. According to the revised literature, it is possible to reduce the use of restraints and coercive measures and not increase the number of incidents and violent behaviors among the patients through a non-invasive and non-pharmacological approach. However, further research and further randomized clinical trials are needed to compare the different alternatives and provide higher quality evidence.

Time from the Admission as the Predictor of Aggressive Behavior of Inpatients with Schizophrenia Spectrum Disorder

The aim was to assess the incidence of aggressive events (AE) committed by patients diagnosed with schizophrenia spectrum disorethder (SSD) after the first 7 days of hospitalization in psychiatric institution, in comparison to other psychiatric patients. This retrospective cohort study was performed at Psychiatric Hospital "Sveti Ivan", Zagreb, Croatia, using hospital safety records of all patients admitted between 2015 and 2017. Primary outcome was the proportion of patients who committed AE more than a week after the admission to the hospital. Secondary outcome was the time in days from admission to the first incident of AE. The primary analysis was performed using a multivariable binary logistic regression. SSD patients committed AE more often than other patients (incidence rate ratio 3.97 (95% CI 2.35-6.69; p < 0.001; FDR q = 0.002), but these occurred earlier in the course of hospitalization: median (IQR) 2 (1-10) days from admission compared to 11 (2-32) days in other patients. SSD patients had significantly and clinically relevantly lower odds for AE after the first week of hospitalization adjusted for the large number of pre-planned possible confounders (OR = 0.10; 95% CI 0.02-0.45; p = 0.003; FDR q = 0.002). SSD patients seem to express more aggression earlier in the course of hospitalization. Findings of this study indicate that hospitalization-inherent AE risk factors may play an important role in the etiology of AE and inpatients aggressive behavior. Their possible moderating effect should be included in risk-assessment instruments.

Cytokines in agitated and non-agitated patients admitted to an acute psychiatric department: A cross-sectional study

BACKGROUND

Different psychiatric diagnostic groups have been reported to have cytokine levels deviating from healthy controls. In acute clinical settings however, the specific challenging symptoms and signs are more important than a diagnostic group. Thus, exploration of cytokines and immune activity and their role in specific symptoms is important. Reports in this field so far are sparse.

OBJECTIVE

In the present study, we aimed to examine the association between immune activity measured as levels of cytokines and agitation (independent of diagnostic group) in patients admitted to an acute psychiatric inpatient department.

METHODS

A total of 316 patients admitted to an acute psychiatric inpatient department were included. Thirty-nine patients with psychosis were subject to subgroup analyses. Agitation was assessed by the Positive and Negative Syndrome Scale, Excitement Component (PANSS-EC). Based on PANNS-EC patients were stratified into two groups: 67 agitated patients and 249 non-agitated patients. Serum concentrations of the following immune markers were measured: interleukin (IL) -1β, IL-4, IL-6, IL-10, tumor necrosis factor (TNF) -α, interferon (IFN) -γ and transforming growth factor (TGF) -β.

RESULTS

Serum levels of TNF-α were significantly higher in patients with agitation compared to those without, both when all patients were included in the analyses (p = 0.004) and in the psychosis group (p = 0.027). After correcting for multiple testing, only the findings in the total population remained significant.

CONCLUSIONS

Our findings suggest an association between TNF-α and agitation in an acute psychiatric population. A similar trend was reproduced to the psychosis subgroup. This suggests that agitation might be an independent entity associated with cytokines across different diagnostic groups.

Manic episode, aggressive behavior and poor insight are significantly associated with involuntary admission in patients with bipolar disorders

Objectives

Serious mental illnesses, such as bipolar disorders and schizophrenia, are closely associated with involuntary admission. Many studies have focused on involuntary admission in people with schizophrenia, but little is known about the factors associated with involuntary admission in Chinese patients with bipolar disorders. This study aimed to investigate socio-demographic and clinical factors associated with involuntary admission in Chinese patients with bipolar disorders.

Methods

In this multi-center cross-sectional survey in China, a total of 155 newly admitted patients with bipolar disorders were consecutively recruited from 16 psychiatric institutions from 15 March to 14 April, 2013. Patients' socio-demographic and clinical data were collected from their medical records. The Modified Overt Aggression Scale and the Insight and Treatment Attitudes Questionnaire were used to measure patients' level of aggression and insight of current psychiatric illness.

Results

The prevalence of involuntary admission was 52% in this sample of Chinese inpatients with bipolar disorders. In multiple logistic regression, a high level of aggression (odds ratio (OR) = 2.48), diagnosis of manic episode (OR = 3.65), poor insight (OR = 7.52), and a low level of education (OR = 3.13) were significantly associated with involuntary admission.

Conclusion

Manic episode, aggressive behavior, and poor insight were the significant contributing factors to involuntary admission in Chinese patients with bipolar disorders.

Prescription practices in the treatment of agitation in newly hospitalized Chinese schizophrenia patients: data from a non-interventional naturalistic study

BACKGROUND

Data on the pharmacological management of acute agitation in schizophrenia are scarce. The aim of this study is to investigate the prescription practices in the treatment of agitation in Chinese patients with schizophrenia.

METHODS

We conducted a large, multicenter, observational study in 14 psychiatry hospitals in China. Newly hospitalized schizophrenia patients with the PANSS-EC total score ≥ 14 and a value ≥4 on at least one of its five items were included in the study. Their drug treatments of the first 2 weeks in hospital were recorded by the researchers.

RESULTS

Eight hundred and 53 patients enrolled in and 847 (99.30%) completed the study. All participants were prescribed antipsychotics, 40 (4.72%) were prescribed benzodiazepine in conjunction with antipsychotics and 81 were treated with modified electric convulsive therapy (MECT). Four hundred and 12 (48.64%) patients were prescribed only one antipsychotic, in the order of olanzapine (120 patients, 29.13%), followed by risperidone (101 patients, 24.51%) and clozapine (41 patients, 9.95%). About 435 (51.36%) participants received antipsychotic polypharmacy, mostly haloperidol + risperidone (23.45%), haloperidol+ olanzapine (17.01%), olanzapine+ ziprasidone (5.30%), haloperidol + clozapine (4.37%) and haloperidol + quetiapine (3.90%). Binary logistic regression analysis suggests that a high BARS score (OR 2.091, 95%CI 1.140-3.124), severe agitation (OR 1.846, 95%CL 1.266-2.693), unemployment or retirement (OR 1.614, 95%CL 1.189-2.190) and aggressiveness on baseline (OR 1.469, 95%CL 1.032-2.091) were related to an increased antipsychotic polypharmacy odds. Male sex (OR 0.592, 95%CL 0.436-0.803) and schizophrenia in older persons (age ≥ 55 years, OR 0.466, 95%CL 0.240-0.902) were less likely to be associated with antipsychotic polypharmacy.

CONCLUSION

The present study demonstrates that monotherapy and polypharmacy display equally common patterns of antipsychotic usage in managing agitation associated with schizophrenia in China. The extent and behavioral activities of agitation and several other factors were associated with polypharmacy.

Inhaled Loxapine for the Management of Acute Agitation in Bipolar Disorder and Schizophrenia: Expert Review and Commentary in an Era of Change

Agitation is a common and costly phenomenon associated with a number of psychiatric conditions including schizophrenia and bipolar disorder. Early identification and prompt intervention to relieve the symptoms of agitation are essential to avoid symptomatic escalation and emergence of aggressive behaviour. Recent consensus guidelines emphasise the need for non-coercive management strategies to protect the therapeutic alliance between patients and their healthcare providers—an alliance that is critical for the effective management of chronic psychiatric conditions. Rapid symptom relief and de-escalation of agitation are necessary to avoid the costly and traumatic use of coercive techniques of physical restraint and seclusion, which require admission and prolonged hospitalisation. Inhaled loxapine is approved for the treatment of acute agitation in patients with schizophrenia or bipolar disorder. Clinical studies have confirmed the efficacy, rapid onset of action, and safety and tolerability of this agent in the psychiatric emergency and hospital settings. Emerging data have indicated the potential for inhaled loxapine as a self-administered agent for use in the community setting without the direct supervision of a healthcare professional. We discuss the evolving treatment paradigm and the place of inhaled medications for acutely agitated patients both within and outside the emergency and hospital setting.

Characterizing the inpatient care of young adults experiencing early psychosis: A medical record review

AIM

To characterize the inpatient care received by individuals experiencing early psychotic episodes in an inner city hospital.

METHOD

Medical records of patients admitted between April 01, 2013, and March 31, 2015, to a psychiatric ward at an inner city hospital were retrospectively examined. Included in the study are patients who were 25 years of age or younger and were hospitalized for psychotic symptoms. Demographics and health service use were summarized using descriptive statistics.

RESULTS

A total of 73 inpatients (mean age = 22; males =78%; Caucasian = 41%) met the study inclusion criteria with a combined total of 102 care episodes and an average length of stay of 32.6 days. Monitoring of vital signs (VS) and mental status examinations (MSE) were performed in most care episodes although these were not performed regularly (daily VS checks-31%; MSE every nursing shift-18.6%). In 49% of the care episodes, patients were discharged on long-acting injectable antipsychotics. Even when indicated, not all care episodes had follow-up appointments (82.8%) in the community. The use of seclusion was higher in the wards (32%) than in the emergency department (21%), whereas the use of restraints was higher in the emergency department (16%) than in the wards (<1%).

CONCLUSIONS

There is wide variation in the rate at which various clinical care processes are performed and in the provision of inpatient care to younger adults experiencing episodes of early psychosis. Consistent standards of care are needed to reduce variations and improve treatment outcomes and experiences.

Brazilian guidelines for the management of psychomotor agitation. Part 1. Non-pharmacological approach

Objective:

To present the essential guidelines for non-pharmacological management of patients with psychomotor agitation in Brazil.

Methods:

These guidelines were developed based on a systematic review of articles published from 1997 to 2017, retrieved from MEDLINE (PubMed), Cochrane Database of Systematic Review, and SciELO. Other relevant articles identified by searching the reference lists of included studies were also used to develop these guidelines. The search strategy used structured questions formulated using the PICO model, as recommended by the Guidelines Project of the Brazilian Medical Association. Recommendations were summarized according to their level of evidence, which was determined using the Oxford Centre for Evidence-based Medicine system and critical appraisal tools.

Results:

We initially selected 1,731 abstracts among 5,362 articles. The final sample included 104 articles that fulfilled all the inclusion criteria. The management of agitated patients should always start with the least coercive approach. The initial non-pharmacological measures include a verbal strategy and referral of the patient to the appropriate setting, preferably a facility designed for the care of psychiatric patients with controlled noise, lighting, and safety aspects. Verbal de-escalation techniques have been shown to decrease agitation and reduce the potential for associated violence in the emergency setting. The possibility of underlying medical etiologies must be considered first and foremost. Particular attention should be paid to the patient’s appearance and behavior, physical signs, and mental state. If agitation is severe, rapid tranquilization with medications is recommended. Finally, if verbal measures fail to contain the patient, physical restraint should be performed as the ultimate measure for patient protection, and always be accompanied by rapid tranquilization. Healthcare teams must be thoroughly trained to use these techniques and overcome difficulties if the verbal approach fails. It is important that healthcare professionals be trained in non-pharmacological management of patients with psychomotor agitation as part of the requirements for a degree and graduate degree.

Conclusion:

The non-pharmacological management of agitated patients should follow the hierarchy of less invasive to more invasive and coercive measures, starting with referral of the patient to an appropriate environment, management by a trained team, use of verbal techniques, performance of physical and mental assessment, use of medications, and, if unavoidable, use of the mechanical restraint.

Resource Utilization with the Use of Seclusion and Restraint in a Dedicated Emergency Psychiatric Service

OBJECTIVES

There is a dearth of data regarding the use of emergency interventions in dedicated emergency psychiatric service settings, and reliable data are needed. This article describes the frequency and duration of the use of seclusion and restraint for imminent or existing agitation, aggression, or violence in a dedicated emergency psychiatric service located within an academic university hospital and staffed by sufficient numbers of trained personnel.

METHODS

We performed a retrospective chart review of 6 months' visits to a dedicated emergency psychiatric service.

RESULTS

Men outnumbered women with a 1.6 ratio of visits. Of 2843 subjects, 425 (14.6%) received emergent medication for anxiety (n = 90), substance withdrawal (n = 28), or agitation (n = 290). Physical interventions were used in 3.4%; 96 (3.3%) were secluded, and 9 (0.3%) were restrained. The average duration of seclusion was (mean ± standard deviation) 58.7 ± 37.4 minutes and for restraint 63.2 ± 23.4 minutes. Each episode of seclusion or restraint required approximately 3 hours of staff time.

CONCLUSIONS

The use of an intervention such as seclusion in >3% and restraint in 0.3% of patients represents the use of seclusion and restraint in a dedicated psychiatric emergency service with personnel trained to minimize the use of seclusion and restraint.

Safety and efficacy of self-administered inhaled loxapine (ADASUVE) in agitated patients outside the hospital setting: protocol for a phase IV, single-arm, open-label trial

INTRODUCTION

There is a need for fast-acting, non-injection antiagitation treatments that are well tolerated and can be used outside of healthcare facilities. In phase II/III trials, an inhaled formulation of loxapine (ADASUVE®), a well-established, first-generation antipsychotic agent, provided rapid control of mild to moderate agitation in the hospital setting. The present study was designed to investigate the safety and efficacy of inhaled loxapine when self-administered outside the hospital setting.

METHODS AND ANALYSIS

This phase IV, multicentre, single-arm, open-label clinical trial is being conducted in five countries in Europe: Spain, Germany, Norway, Romania and Austria. The aim is to include approximately 500 patients with schizophrenia or bipolar disorder who previously received and responded well to inhaled loxapine in the hospital setting. Eligible patients will be followed up for 6 months from baseline. They will be given a 10 mg dose of inhaled loxapine to self-administer outside the hospital setting to treat an agitation episode, should one occur. Patients will also be given a short-acting beta-agonist bronchodilator for treatment of possible severe respiratory side effects. The primary endpoint is incidence of serious adverse events (AEs) and respiratory AEs of special interest related to use of inhaled loxapine outside the hospital setting. Secondary endpoints include incidence of other AEs, Clinical Global Impression-Improvement scores up to 2 hours after self-administration of inhaled loxapine, time to improvement of agitation, patient satisfaction with treatment, treatment outcomes according to agitation severity and concordance between the patient (or a family member/caregiver) and the physician in scoring of agitation severity and the decision to self-administer inhaled loxapine.

ETHICS AND DISSEMINATION

The protocol received ethics committee approval in the participating countries between January and August 2016. The results of this study will be disseminated through one or more scientific papers.

Intravenous Valproic Acid Add-On Therapy in Acute Agitation Adolescents With Suspected Substance Abuse: A Report of Six Cases

The aim of this study was to test efficacy and safety of intravenous (IV) valproate for aggression in children and adolescents with mood or conduct disorder and concomitant substance abuse. Six patients received a 20 mg/kg dose of IV valproic acid as an add-on therapy to their standard therapy with second-generation antipsychotics and benzodiazepines. Agitation and general psychopathology were measured at baseline and after the first injection using the Modified Overt Aggression Scale, the Brief Psychiatric Rating Scale, and the Children's Global Assessment Scale. The findings suggested that in emergency psychiatry clinical settings, IV valproate was effective in reducing agitation and aggressive behaviors with a good tolerability profile and better treatment compliance.

Characterizing the experience of agitation in patients with bipolar disorder and schizophrenia

BACKGROUND

Agitation is a common manifestation of bipolar disorder and schizophrenia which includes symptoms ranging from inner tension and unease to violence and aggression. Much of the existing literature has focused on agitation in the acute setting, with the patient experience poorly defined. Thus, the aim of this study was to characterize agitation and its management from a patient perspective, with the focus on those who reside in the community.

METHODS

Surveys were completed across Germany, Spain and the UK by 583 community dwelling patients with schizophrenia or bipolar disorder who experienced episodes of agitation. Patients were recruited via either their physician or through patient support groups. The survey captured information on demographics, disease characteristics, frequency of agitation episodes and different pre-defined severity levels ranging from mild to severe, symptoms experienced during an episode, awareness of agitation and coping strategies employed by the patient. Statistics were descriptive in nature.

RESULTS

The most commonly reported symptoms during an episode of agitation were feeling uneasy (n = 373, 64%), restless (n = 368, 63%) or nervous (n = 368, 63%). Patients experienced an average of 22.4 (SD 57.2) mild, 15.4 (SD 61.2) moderate, 6.8 (SD 63.3) moderate-intense and 2.9 (SD 24.4) severe episodes within the last 12 months; on average 2.7 (SD 6.8) required hospital attendance. Half of patients (n = 313) had attended hospital due to agitation. In total, 71% of patients (n = 412) were aware they were becoming agitated either always or sometimes and 61% of patients (n = 347) were aware of agitation triggers either always or sometimes. The majority of patients reported being able to sometimes control their agitation (56%, n = 329) but 16% (n = 94) stated that there is typically nothing they can do. To cope with episodes 55% (n = 125) of schizophrenia patients and 66% (n = 234) of bipolar disorder patients reported taking prescribed medication.

CONCLUSION

Community based patients with schizophrenia and bipolar disorder reported frequently experiencing agitation episodes which they defined most commonly as feeling uneasy, restless or nervous. A range of coping strategies were reported but they were not always successful, highlighting an area of unmet need in this population.

1st International Experts' Meeting on Agitation: Conclusions Regarding the Current and Ideal Management Paradigm of Agitation

Agitation is a heterogeneous concept without a uniformly accepted definition, however, it is generally considered as a state of cognitive and motor hyperactivity characterized by excessive or inappropriate motor or verbal activity with marked emotional arousal. Not only the definition but also other aspects of agitated patients' care are still unsolved and need consensus and improvement. To help the discussion about agitation among experts and improve the identification, management, and treatment of agitation, the 1st International Experts' Meeting on Agitation was held in October 2016 in Madrid. It was attended by 20 experts from Europe and Latin America with broad experience in the clinical management of agitated patients. The present document summarizes the key conclusions of this meeting and highlights the need for an updated protocol of agitation management and treatment, the promotion of education and training among healthcare professionals to improve the care of these patients and the necessity to generate clinical data of agitated episodes.

A survey of caregiver burden in those providing informal care for patients with schizophrenia or bipolar disorder with agitation: results from a European study

BACKGROUND

Agitation is a common feature of bipolar disorder and schizophrenia. Previous research indicates that specific symptoms impact caregiver burden in these conditions, but the impact of agitation on caregiver experience is poorly understood. The aim of this study was to characterise caregiver burden in providers of informal care for patients with bipolar disorder and schizophrenia who experience agitation.

METHODS

In total, 297 matched patient and caregiver surveys were collected across the UK, Germany and Spain between October 2016 and January 2017. To be eligible, caregivers needed to provide informal care to a patient with a diagnosis of bipolar disorder or schizophrenia with agitation managed in a community setting and participating in the patient survey. The caregiver survey captured information on demographics and their role in managing the patient's agitation. Caregiver burden was assessed using the Involvement Evaluation Questionnaire. Descriptive analysis was conducted.

RESULTS

Caregivers provided 38.3 h (SD ± 40.34) a week of support to the patient with 20% providing 50 h or more. Most caregivers reported that they recognised an episode of agitation all of the time (44%, n = 130) or sometimes (40%, n = 119). Verbal de-escalation techniques (talking (80%, n = 239) and soothing (73%, n = 218) were the most commonly reported strategies used by caregivers during an episode of agitation; 14% (n = 43) reported resorting to physically restraining the patient. Caregivers supervised rescue medication administration regularly (41%, n = 69) or occasionally (49%, n = 82). Mean Involvement Evaluation Questionnaire score was 32.2 (± 15.27), equivalent to 28.4 (± 13.56) in Germany, 35.6 (± 16.55) in Spain and 33.3 (± 15.15) in the UK. Involvement Evaluation Questionnaire scores were higher for caregivers who reported hostile (41.7 ± 17.07) lack of control (40.3 ± 16.35) and violent (39.5 ± 16.40) patient behaviours when agitated. Over excitement (31.8 ± 15.05), restless (32.6 ± 14.77) and tense (32.9 ± 15.64) behaviours were associated with a lower Involvement Evaluation Questionnaire score.

CONCLUSIONS

Caregivers are active participants in the recognition and management of agitation episodes. The substantial burden reported by these caregivers is impacted by factors including the number of hours of care provided, patient behaviours and country. These may be viable targets for effective interventions to reduce caregiver burden.

[Psychiatric emergencies]

Psychiatric emergencies present a frequent and interdisciplinary challenge. Clinical diagnosis and management are complicated by the acuity, and the patient's compliance is often limited by the illness. Psychiatric emergencies include states of acute agitation, suicidality, delirium, stupor, and drug-induced emergencies. Sometimes interventions such as conversational contact, responding empathically to patients, or "talking down" are sufficient. If pharmacotherapy is necessary, benzodiazepines and antipsychotic drugs are the primary agents of choice.
