The effectiveness of chemical restraint in managing acute agitation and aggression: A systematic review of randomized controlled trials

Advancing Emergency Medical Services' (EMS) Response Capability for Behavioral Health Emergencies: Los Angeles County's Performance Improvement Initiative

INTRODUCTION

Behavioral health emergencies (BHEs) are a common patient encounter for emergency medical services (EMS) clinicians and other first responders, in particular law enforcement (LE) officers. It is critical for EMS clinicians to have management strategies for BHEs, yet relatively little information exists on best practices. In 2016, the Los Angeles County EMS Agency's Commission initiated a comprehensive evaluation of the 9-1-1 response for BHEs and developed a plan for improving the quality of care and safety for patients and first responders.

METHODS

A Behavioral Health Initiative Committee was assembled with broad representation from EMS, LE, health agencies, and the public. Committee objectives included: 1) produce a process map of the BHE response from the time of a 9-1-1 call to patient arrival at transport destination, 2) identify and describe the different agencies that respond, 3) describe the critical decision points in the EMS and LE field responses, 4) acquire data that quantitatively and/or qualitatively describe the services available, and 5) recommend interventions for system performance improvement.

RESULTS

The committee generated comprehensive process maps for the prehospital response to BHEs, articulated principles for evaluation, and described key observations of the current system including: 9-1-1 dispatch criteria are variable and often defaults to a LE response, the LE response inadvertently criminalizes BHEs, EMS field treatment protocols for BHEs (and especially agitated patients) are limited, substance use disorder treatment lacks integration, destination options differ by transporting agency, and receiving facilities' capabilities to address BHEs are variable. Recommendations for performance improvement interventions and initial implementation steps included: standardize dispatch protocols, shift away from a LE primary response, augment EMS treatment protocols for BHEs and the management of agitation, develop alternate destination for EMS transport.

CONCLUSION

This paper describes a comprehensive performance improvement initiative in LAC-EMSA's 9-1-1 response to BHEs. The initiative included a thorough current state analysis, followed by future state mapping and the implementation of interventions to reduce LE as the primary responder when an EMS response is often warranted, and to improve EMS protocols and access to resources for BHEs.

Evidence synthesis on coercion in mental health: An umbrella review

Coercion in mental healthcare is ubiquitous and affects the physical health, recovery and psychological and emotional well-being of those who experience it. Numerous studies have explored different issues related to coercion, and the present umbrella review aims to gather, evaluate and synthesise the evidence found across systematic reviews. The protocol, registered in the International Prospective Register of Systematic Reviews (PROSPERO registration number: CRD42020196713), included 46 systematic reviews and meta-analyses of primary studies whose main theme was coercion and which were obtained from databases (Medline/PubMed, PsycINFO, EMBASE and CINAHL) and repositories of systematic reviews following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. All the reviews were subjected to independent assessment of quality and risk of bias and were grouped in two categories: (1) evidence on specific coercive measures (including Community Treatment Orders, forced treatment, involuntary admissions, seclusion and restriction and informal coercion), taking into account their prevalence, related factors, effectiveness, harmful effects and alternatives to reduce their use; and (2) experiences, perceptions and attitudes concerning coercion of professionals, mental health service users and their caregivers or relatives. This umbrella review can be useful to professionals and users in addressing the wide variety of aspects encompassed by coercion and the implications for professionals' daily clinical practice in mental health units. This research received funding from two competitive calls.

Management of the Agitated Patient

The acutely agitated patient should be managed in a step-wise fashion, beginning with non-coercive de-escalation strategies and moving on to pharmacologic interventions and physical restraints as necessary. Face-to-face examination, monitoring, and documentation by the physician are essential. The emergency physician should be familiar with multiple pharmaceutical options, tailored to the individual patient. Use of ketamine, benzodiazepines and antipsychotics should be considered. Patient autonomy, safety, and medical well-being are paramount.

Mental Healthcare workers' experiences in managing psychiatric patients' aggression in Maseru

Background

Aggression and violence in psychiatric clinical facilities are a common case, and mental healthcare workers utilise various management strategies to combat it. It is therefore crucial for mental healthcare workers to acquire skills for the management strategies of aggressive behaviour of psychiatric patients.

Aim

The aim of the study was to describe mental healthcare workers' experiences in the management strategies of aggressive and violent behaviour by psychiatric patients in Maseru district.

Setting

A psychiatric hospital situated to the south in Maseru in the rural countryside and general hospital located in the western lowlands of Lesotho in the village of Morija were used.

Methods

This study adopted a qualitative, exploratory, descriptive and contextual research design. There were two focus group interviews conducted per clinical facility, which consisted of six members in each group. There were four participants for individual interviews from psychiatric clinical facility and three individual interviews from general clinical facility.

Results

Thematic analysis of the data resulted in themes and sub-themes. These were psychological intervention strategy, physical strategy, chemical strategy, empowerment strategy and policy strategy. Participants viewed various management strategies of aggressive and violent behaviour of psychiatric patients they utilise in clinical facilities as effective.

Conclusion

The mental healthcare workers' experiences in managing aggression and violent behaviour of psychiatric patients were expression of psychological, physical, chemical, empowerment and policy strategies.

Contribution

The study will enhance the knowledge, skills and attitudes regarding management strategies that mental healthcare workers can utilise in managing aggressive and violent behaviour of psychiatric patients.

Nurses' use of pro re nata medication in adult acute mental healthcare settings: An integrative review

This integrative review explores the current pro re nata (PRN) medication practice in acute adult mental health settings. PRN medication is commonly used in acute mental health settings but there is lack of evidence of effectiveness of this practice. PRN medications have a number of adverse effects and increase the risk of morbidity in patients with a mental illness. Articles were identified from MEDLINE, CINAHL, Scopus, PubMed, PsycINFO, and Web of Science database. The STROBE critical appraisal tool was used to evaluate the quality of evidence, and inductive thematic analysis was used to extract main themes. Five themes regarding prescription practices, poor documentation, reasons to administer, medication misuse, and insufficient use of non-pharmacological interventions emerged among the 12 eligible articles. The study identified PRN medication practice gaps in adult mental health settings included insufficient documentation practice, underuse of therapeutic non-pharmacological interventions, and significant variability in PRN medication practice across the mental health professionals due to different levels of knowledge and experience.

Nurses' clinical decision-making in the use of rapid tranquillization in adult mental health inpatient settings: An integrative review

Rapid tranquillization is a restrictive practice that remains widely used in mental health inpatient settings worldwide. Nurses are the professionals most likely to administer rapid tranquillization in mental health settings. To improve mental health practices, an enhanced understanding of their clinical decision-making when using rapid tranquillization is, therefore, important. The aim was to synthesize and analyse the research literature on nurses' clinical decision-making in the use of rapid tranquillization in adult mental health inpatient settings. An integrative review was conducted using the methodological framework described by Whittemore and Knafl. A systematic search was conducted independently by two authors in APA PsycINFO, CINAHL Complete, Embase, PubMed and Scopus. Additional searches for grey literature were conducted in Google, OpenGrey and selected websites, and in the reference lists of included studies. Papers were critically appraised using the Mixed Methods Appraisal Tool, and the analysis was guided by manifest content analysis. Eleven studies were included in this review, of which nine were qualitative and two were quantitative. Based on the analysis, four categories were generated: (I) becoming aware of situational changes and considering alternatives, (II) negotiating voluntary medication, (III) administering rapid tranquillization and (IV) being on the other side. Evidence suggests that nurses' clinical decision-making in the use of rapid tranquillization involved a complex timeline with various impact points and embedded factors that continuously influenced and/or were associated with nurses' clinical decision-making. However, the topic has received scant scholarly attention, and further research may help to characterize the complexities involved and improve mental health practice.

The Use of Alternative Rooms in Forensic and Regular Psychiatric Units: A Scoping Review

(1) Background: Emotional regulation, distress and relational conflicts often occur during hospitalization and rehabilitation on psychiatric units, especially in patients suffering from severe and persistent mental disorders. While widely used in children and geriatric patients, little literature exists on the use and outcomes of alternative rooms in the context of forensic and regular psychiatric units for adult patients. Considering the scarcity of the literature on alternative use, this study is motivated by the following research question: what are the main uses and outcomes of alternative rooms in the context of forensic and regular psychiatric units? The main objective of this study is to conduct a scoping review of the use and outcomes of alternative rooms for the context of psychiatric inpatients. (2) Methods: A systematic search was performed in the electronic databases of MedLine, Web of Science, PsycNet (PsycINFO) and Google Scholar from their inception dates until 2022. (3) Results: A total of nine studies were analyzed. Sensory, multisensory rooms, Snoezelen, and comfort rooms are the types of alternative rooms discussed in these studies. Distress and anxiety reduction, increase in self-esteem, impact on seclusion rates, patient-staff communication and alliances, heart and respiration rate reduction, and improvement of alexithymia were identified among the main uses and outcomes of these rooms. (4) Conclusions: The scarcity of literature available to draw information from for this review and possible impact on improving patient outcomes and quality of treatment in psychiatric units opens the door to future studies to better understand the efficacy of such rooms. Research into the ideal implementation tactics of such rooms, long-term outcomes, and the influence on diverse patient demographics could be areas of improvement in the use of alternative rooms.

Chemical restraint as behavioural euthanasia: case studies from the Royal Commission into Aged Care Quality and Safety

BACKGROUND

The prescription of psychotropic medication to older people living with dementia in residential aged care has become an increasing concern. The use of prescription medication is often prefaced as a way of preventing harm to self and others. However, the use of such medications has been considered a way of managing some of the behavioural and psychological symptoms of dementia. Using a large secondary data set, this study aimed to identify the precursors and mediating factors that influence the use of chemical restraint of older people in residential aged care.

METHODS

Publicly available documents from the Australian Royal Commission into Aged Care Quality and Safety were used as the data corpus for this study. Keywords were used to search over 7000 documents to extract a set of topic-related content. We identified the cases of seven people in respite or permanent residential aged care who had been prescribed or administered psychotropic medication under circumstances that appeared to demonstrate chemical restraint. All documents relating to the cases were collated for our data set. A descriptive case study approach to analysis was taken.

RESULTS

Four key descriptive patterns were identified: labelling and limits to tolerance, pushing prescription as a solution, coverups and avoiding consent, and family's fight for liberty. Triangulation across the data and academic literature supports the findings.

CONCLUSION

Our findings provide some insight into how chemical restrain happens. Featuring throughout the cases were reports of a lack of workforce capacity to care for and support residents exhibiting dementia behaviours. Prescription of psychotropic medications featured as a "first resort" care solution. Family and friends found such approaches to care unacceptable and frequently challenged the practice. Where consent for prescription was explicitly denied, more covert approaches are demonstrated. Family awareness, presence, and advocacy were key to challenging the practice of chemical restraint. Shortfalls in the capacity of the current workforce come into play here. However, workforce shortcomings can no longer mask this ubiquitous practice. Just as importantly the spotlight needs to be turned on the prescribers and the providers.

Forensically relevant challenging behaviors and the genetics domain

Impulsive and aggressive behaviors along with intellectual disabilities often manifest in the context of genetic disorders and are a persisting challenge to professionals in the forensic psychiatric and psychological setting. The following chapter comprises an overview of relevant factors in the gene-context-behavior interaction such as monoamine oxidase A activity and specific epileptic phenomena. It presents several examples of monogenetic disorders with behaviors from the aggression spectrum and summarizes emerging strategies for treatment and clinical management thereof. The final part focuses on challenges and future developments in this field with relevance for the judicial and forensic systems. It is concluded that the relationship between a genetic syndrome and forensically relevant and/or violent behaviors should typically be addressed within a multidisciplinary framework that also includes the application of modern genetic techniques.

Pharmacologic Therapy to Mitigate Acute Agitation in the Emergency Department: Case Reports of Diverse Patient Presentations

Nurses in the emergency department often encounter patients exhibiting signs of aggressive behavior. Nurses need to know the pharmacologic treatment appropriate for the patient scenario to ensure safety for the patient and the emergency department team. This case review examines 4 common scenarios where a patient exhibits aggressive behavior. After each case review is a discussion about the appropriate pharmacologic therapy for that patient. The cases portrayed are fictional but based on experience and previous observations.

Intubation Rates following Prehospital Administration of Ketamine for Acute Agitation: A Systematic Review and Meta-Analysis

BACKGROUND

Ketamine is a fast-acting, dissociative anesthetic with a favorable adverse effect profile that is effective for managing acute agitation as a chemical restraint in the prehospital and emergency department (ED) settings. However, some previously published individual studies have reported high intubation rates when ketamine was administered prehospitally.

OBJECTIVE

This systematic review aims to determine the rate and settings in which intubation following prehospital administration of ketamine for agitation is occurring, as well as associated indications and adverse events.

METHODS

We searched PubMed, Scopus, Ovid MEDLINE, Embase, CINAHL Plus, PsycINFO, the Cochrane Library, ClinicalTrials.gov, OpenGrey, Open Access Theses and Dissertation, and Google Scholar from the earliest possible date until 13/February/2022. Inclusion criteria required studies to describe agitated patients who received ketamine in the prehospital setting as a first-line drug to control acute agitation. Reference lists of appraised studies were screened for additional relevant articles. Study quality was assessed using the Newcastle-Ottawa quality assessment scale. Synthesis of results was completed via meta-analysis, and the GRADE tool was used for certainty assessment.

RESULTS

The search yielded 1466 unique records and abstracts, of which 50 full texts were reviewed, resulting in 18 being included in the analysis. All studies were observational in nature and 15 were from USA. There were 3476 patients in total, and the overall rate of intubation was 16% (95% confidence interval [CI] = 8%-26%). Most intubations occurred in the ED. Within the studies, the prehospital intubation rate ranged from 0% to 7.9% and the ED intubation rate ranged from 0 to 60%. The overall pooled prehospital intubation rate was 1% (95% CI = 0%-2%). The overall pooled ED intubation rate was 19% (95% CI = 11%-30%). The most common indications for intubation were for airway protection and respiratory depression/failure.

CONCLUSIONS

There is wide variation in intubation rates between and within studies. The majority of intubations performed following prehospital administration of ketamine for agitation took place in the ED.

Complexity, safety and challenges: Emergency responders’ experience of people affected by methamphetamines

Providing care to methamphetamine‐related callout events in the prehospital environment is often complex and resource‐intensive, requiring staff to manage agitation and violence‐related side effects of methamphetamines. In Australia, emergency responders are increasingly required to attend events related to methamphetamines, even though reports suggest methamphetamine use across Australia has declined. The aim of the study was to explore Australian police and paramedic experiences attending methamphetamine‐related events. A qualitative descriptive phenomenology design was employed using semi‐structured interviews with employed police (10) and paramedics (8) from Australia. Data were analyzed using thematic analysis. Participants described the complexities associated with providing prehospital care to people affected by methamphetamines. Participants described associated domestic/family violence, increased levels of violence, challenges with communication, and responder emotional and psychological distress and physical injury. Violence associated with methamphetamine use is a critical factor in prehospital care. Workplace violence and family/domestic violence are important issues that require further research to ensure families and staff are well supported and have the services they need to continue responding to people affected by methamphetamine use.

Cost-Effectiveness of Midazolam Versus Haloperidol Versus Olanzapine for the Management of Acute Agitation in the Accident and Emergency Department

OBJECTIVES

A multicenter randomized clinical trial in Hong Kong Accident and Emergency (A&E) departments concluded that intramuscular (IM) olanzapine is noninferior to haloperidol and midazolam, in terms of efficacy and safety, for the management of acutely agitated patients in A&E setting. Determining their comparative cost-effectiveness will further provide an economic perspective to inform the choice of sedative in this setting.

METHODS

This analysis used data from a randomized clinical trial conducted in Hong Kong A&E departments between December 2014 and September 2019. A within-trial cost-effectiveness analysis comparing the 3 sedatives was conducted, from the A&E perspective and a within-trial time horizon, using a decision-analytic model. Sensitivity analyses were also undertaken.

RESULTS

In the base-case analysis, median total management costs associated with IM midazolam, haloperidol, and olanzapine were Hong Kong dollar (HKD) 1958.9 (US dollar [USD] 251.1), HKD 2504.5 (USD 321.1), and HKD 2467.6 (USD 316.4), respectively. Agitation management labor cost was the main cost driver, whereas drug costs contributed the least. Midazolam dominated over haloperidol and olanzapine. Probabilistic sensitivity analyses supported that midazolam remains dominant > 95% of the time and revealed no clear difference in the cost-effectiveness of IM olanzapine versus haloperidol (incremental cost-effectiveness ratio 667.16; 95% confidence interval -770.89, 685.90).

CONCLUSIONS

IM midazolam is the dominant cost-effective treatment for the management of acute agitation in the A&E setting. IM olanzapine could be considered as an alternative to IM haloperidol given that there is no clear difference in cost-effectiveness, and their adverse effect profile should be considered when choosing between them.

Triggers of Agitation in Psychiatric Hospitalization Ward According to Professional Experience Questionnaire

AIM

To create and analyze an instrument to assess the possible agitation triggers of hospitalized psychiatric patients.

BACKGROUND

No tools exist for identifying according to a professional's experience.

METHODS

Descriptive and cross-sectional study. The questionnaire of possible triggers of agitation behaviors of patients hospitalized in psychiatric wards according to professional experience (TAPE) was designed and analyzed.

RESULTS

The questionnaire was provided to 156 mental health workers (76.9% women, average work experience: 10.15 ± 8 years, 46.8% were nurses specialized in mental health, and 21.2% psychiatrists). A good internal consistency was obtained, with a Cronbach α value of 0.791 in the initial test, and 0.892 in the retest. The factorial analysis found four factors: factor 1 "personnel", factor 2 "routines", factor 3 "norms-infrastructure", and factor 4 "clinic". Factor 1 obtained the highest value, with a mean of 4.16 ± 0.63, highlighting the item "lack of specialized personnel" (mean 4.38 ± 0.81). The specialized professionals provided higher scores to the items from the factors associated with the training of the personnel and routines (p = 0.017; p = 0.042).

CONCLUSIONS

The TAPE questionnaire is useful for identifying the possible triggers that could lead to situations of agitation of hospitalized patients.

A comparison of aggression between patients with acute schizophrenia and mania presenting to psychiatric emergency services

OBJECTIVE

Aggression is common and challenging in psychiatric emergency departments (PED). However, the prevalence of aggression and its correlates in PED patients are not well documented. This study compared the prevalence of aggression between patients with acute schizophrenia and manic episodes.

METHODS

In this cross-sectional study, patients at a psychiatric emergency department were assessed with measurements of aggression, psychotic and manic symptoms.

RESULTS

A total of 4,172 patients were included. The prevalence of aggression was 54.8% (95%CI=53.3%-65.2%) in the whole sample, with 48.0% (95%CI=45.8%-50.1%) in patients with an acute schizophrenia episode, and 61.8% (95%CI=59.8%-63.9%) in patients with a manic episode. Multiple logistic regression analysis revealed that, within the acute schizophrenia episode group, male gender (OR=1.47, P<0.01), involuntary admission (OR=3.61, P<0.01) and more severe manic symptoms (OR=1.30, P<0.01) were significantly associated with aggression. Within the manic episode group, living in Beijing (OR=1.51, P<0.01), unemployment (OR=1.34, P=0.03), involuntary admission (OR=7.93, P<0.01), lower education (OR=0.95, P=0.01) and more severe psychotic symptoms (OR=1.05, P<0.01) were significantly associated with aggression.

CONCLUSION

In this study, aggression appeared to be more common among patients with a manic episode than those with an acute schizophrenia episode. Considering the significant risk of aggression on psychiatric emergency care, appropriate and effective management of aggression in this population group need to be developed.

Pharmacological and philosophical considerations for the around-the-clock use of scheduled melatonin to promote sedation and reduce aggression in individuals with serious mental illness: a case report

Melatonin, the endogenous hormone that helps maintain circadian rhythm, has been used exogenously for both primary and secondary sleep disorders. While the effects of melatonin given prior to planned sleep and to restore normal circadian sleep phases have been well studied, there is little information on the use of melatonin as a pharmacotherapeutic intervention for around-the-clock sedation to prevent agitation and aggressive patient behaviors. This is the first case report to our knowledge of melatonin used throughout the day, as a scheduled dose for prolonged treatment duration, to reduce aggression in a patient with severe mental illness.

Influence of Organizational Climate and Clinician Morale on Seclusion and Physical Restraint Use in Inpatient Psychiatric Units

OBJECTIVES

Reducing seclusion and restraint use is a prominent focus of efforts to improve patient safety in inpatient psychiatry. This study examined the poorly understood relationship between seclusion and restraint rates and organizational climate and clinician morale in inpatient psychiatric units.

METHODS

Facility-level data on hours of seclusion and physical restraint use in 111 U.S. Department of Veterans Affairs (VA) hospitals in 2014 to 2016 were obtained from the Centers for Medicare & Medicaid Services. Responses to an annual census survey were identified for 6646 VA inpatient psychiatry clinicians for the same period. We examined bivariate correlations and used a Poisson model to regress hours of seclusion and restraint use on morale and climate measures and calculated incident rate ratios (IRRs).

RESULTS

The average physical restraint hours per 1000 patient hours was 0.33 (SD, 1.27; median, 0.05). The average seclusion hours was 0.31 (SD, 0.84; median, 0.00). Physical restraint use was positively associated with burnout (IRR, 1.76; P = 0.04) and negatively associated with engagement (IRR, 0.22; P = 0.01), psychological safety (IRR, 0.48; P < 0.01), and relational climate (IRR, 0.69; P = 0.04). Seclusion was positively associated with relational climate (IRR, 1.69; P = 0.03) and psychological safety (IRR, 2.12; P = 0.03). Seclusion use was also nonsignificantly associated with lower burnout and higher engagement.

CONCLUSIONS

We found significant associations between organizational climate, clinician morale, and use of physical restraints and seclusion in VA inpatient psychiatric units. Health care organization leadership may want to consider implementing a broader range of initiatives that focus on improving organizational climate and clinician morale as one way to improve patient safety.

Current status of perioperative hypnotics, role of benzodiazepines, and the case for remimazolam: a narrative review

Anaesthesiologists and non-anaesthesiologist sedationists have a limited set of available i.v. hypnotics, further reduced by the withdrawal of thiopental in the USA and its near disappearance in Europe. Meanwhile, demand for sedation increases and new clinical groups are using what traditionally are anaesthesiologists' drugs. Improved understanding of the determinants of perioperative morbidity and mortality has spotlighted hypotension as a potent cause of patient harm, and practice must be adjusted to respect this. High-dose propofol sedation may be harmful, and a critical reappraisal of drug choices and doses is needed. The development of remimazolam, initially for procedural sedation, allows reconsideration of benzodiazepines as the hypnotic component of a general anaesthetic even if their characterisation as i.v. anaesthetics is questionable. Early data suggest that a combination of remimazolam and remifentanil can induce and maintain anaesthesia. Further work is needed to define use cases for this technique and to determine the impact on patient outcomes.

Randomized Double-blind Trial of Intramuscular Droperidol, Ziprasidone, and Lorazepam for Acute Undifferentiated Agitation in the Emergency Department

BACKGROUND

The optimal agent to treat acute agitation in the emergency department (ED) has not been determined. The objective of this study was to compare the effectiveness and safety of intramuscular droperidol, ziprasidone, and lorazepam for acute agitation in the ED.

METHODS

This was a randomized, double-blind trial of ED patients with acute agitation requiring parenteral sedation. The study was conducted under exception from informed consent (21 CFR 50.24) from July 2004 to March 2005. Patients were randomized to receive 5 mg of droperidol, 10 mg of ziprasidone, 20 mg of ziprasidone, or 2 mg of lorazepam intramuscularly. We recorded Altered Mental Status Scale (AMSS) scores, nasal end-tidal carbon dioxide (ETCO₂ ), and pulse oximetry (SpO₂ ) at 0, 15, 30, 45, 60, 90, and 120 minutes as well as QTc durations and dysrhythmias. Respiratory depression was defined as a change in ETCO₂ consistent with respiratory depression or SpO₂  < 90%. The primary outcome was the proportion of patients adequately sedated (AMSS ≤ 0) at 15 minutes.

RESULTS

We enrolled 115 patients. Baseline AMSS scores were similar between groups. For the primary outcome, adequate sedation at 15 minutes, droperidol administration was effective in 16 of 25 (64%) patients, compared to seven of 28 (25%) for 10 mg of ziprasidone, 11 of 31 (35%) for 20 mg of ziprasidone, and nine of 31 (29%) for lorazepam. Pairwise comparisons revealed that droperidol was more effective that the other medications, with 39% (95% confidence interval [CI] = 3% to 54%) more compared to 20 mg of ziprasidone and 33% (95% CI = 8% to 58%) more compared to lorazepam. There was no significant difference between groups in need of additional rescue sedation. Numerically, respiratory depression was lower with droperidol (3/25 [12%]) compared to 10 mg of ziprasidone (10/28 [36%]), 20 mg of ziprasidone (12/31 [39%]), or lorazepam (15/31 [48%]). One patient receiving 20 mg of ziprasidone required intubation to manage an acute subdural hematoma. No patients had ventricular dysrhythmias. QTc durations were similar in all groups.

CONCLUSIONS

Droperidol was more effective than lorazepam or either dose of ziprasidone for the treatment of acute agitation in the ED and caused fewer episodes of respiratory depression.

Definition and Measurement of Physical and Chemical Restraint in Long-Term Care: A Systematic Review

This systematic review aimed to identify thematic elements within definitions of physical and chemical restraint, compare explicit and implicit definitions, and synthesize reliability and validity of studies examining physical and/or chemical restraint use in long-term care. Studies were included that measured prevalence of physical and/or chemical restraint use, or evaluated an intervention to reduce restraint use in long-term care. 86 papers were included in this review, all discussed physical restraint use and 20 also discussed chemical restraint use. Seven themes were generated from definitions including: restraint method, setting resident is restrained in, stated intent, resident capacity to remove/control, caveats and exclusions, duration, frequency or number, and consent and resistance. None of the studies reported validity of measurement approaches. Inter-rater reliability was reported in 27 studies examining physical restraint use, and only one study of chemical restraint. Results were compared to an existing consensus definition of physical restraint, which was found to encompass many of the thematic domains found within explicit definitions. However, studies rarely applied measurement approaches that reflected all of the identified themes of definitions. It is necessary for a consensus definition of chemical restraint to be established and for measurement approaches to reflect the elements of definitions.

Chemical restraint: A qualitative synthesis review of adult service user and staff experiences in mental health settings

With an imperative to reduce or eliminate the use of coercive practices in mental health care it is important to understand the experience of service users and staff. This review aimed to synthesize qualitative studies, published between 1996 and 2020, reporting on mental health service users' and staff's experiences of chemical restraint. The databases PsycINFO, CINAHL, MEDLINE, Embase, Emcare, Web of Science, and Scopus were searched. Three analytic themes were identified from 17 included articles, synthesizing the experiences of service users and staff. These were "Unjustified versusjustified," "Violence versus necessity," and "Reflecting back: Positives and negatives." Service users viewed chemical restraint as an unjustified response to "behaviors of concern" and experienced it as a violent act with negative outcomes, although some saw it as necessary in retrospect and preferred it to other forms of coercion. Staff generally viewed it as a justified response to "behaviors of concern" and experienced it as appropriate within the constraints of staff numbers and limited alternatives. These findings identify nuances not apparent in the literature, which has generally conflated all forms of coercive practices.

Which Emergent Medication Should I Give Next? Repeated Use of Emergent Medications to Treat Acute Agitation

Agitation is a common symptom encountered among patients treated in psychiatric emergency settings. While there are many guidelines available for initial management of the acutely agitated patient, there is a notable dearth of guidelines that delineate recommended approaches to the acutely agitated patient in whom an initial medication intervention has failed. This manuscript aims to fill this gap by examining evidence available in the literature and providing clinical algorithms suggested by the authors for sequential medication administration in patients with persistent acute agitation in psychiatric emergency settings. We discuss risk factors for medication-related adverse events and provide options for patients who are able to take oral medications and for patients who require parenteral intervention. We conclude with a discussion of the current need for well-designed studies that examine sequential medication options in patients with persistent acute agitation.
