Physical and Chemical Restraints

Racial, Ethnic, and Age-Related Disparities in Sedation and Restraint Use for Older Adults in the Emergency Department

OBJECTIVES

Older adults may present to the emergency department (ED) with agitation, a symptom often resulting in chemical sedation and physical restraint use which carry significant risks and side effects for the geriatric population. To date, limited literature describes the patterns of differential restraint use in this population.

DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS

This retrospective cross-sectional study used electronic health records data from ED visits by older adults (age ≥65 years) ranging 2015-2022 across nine hospital sites in a regional hospital network. Logistic regression models were estimated to determine the association between patient-level characteristics and the primary outcomes of chemical sedation and physical restraint.

RESULTS

Among 872,587 ED visits during the study period, 11,875 (1.4%) and 32,658 (3.7%) encounters involved the use of chemical sedation and physical restraints respectively. The populations aged 75-84, 85-94, 95+ years had increasingly higher odds of chemical sedation [adjusted odds ratios (AORs) 1.35 (95% CI 1.29-1.42); 1.82 (1.73-1.91); 2.35 (2.15-2.57) respectively] as well as physical restraint compared to the 65-74 group [AOR 1.31 (1.27-1.34); 1.55 (1.50-1.60); 1.69 (1.59-1.79)]. Compared to the White Non-Hispanic group, the Black Non-Hispanic and Hispanic/Latinx groups had significantly higher odds of chemical sedation [AOR 1.26 (1.18-1.35); AOR 1.22 (1.15-1.29)] and physical restraint [AOR 1.12 (95% CI 1.07-1.16); 1.22 (1.18-1.26)].

CONCLUSION

Approximately one in 20 ED visits among older adults resulted in chemical sedation or physical restraint use. Minoritized group status was associated with increasing use of chemical sedation and physical restraint, particularly among the oldest old. These results may indicate the need for further research in agitation management for historically marginalized populations in older adults.

Exploring psychiatric patient restraints: Balancing safety, ethics, and patient rights in mental healthcare

Restraint, often linked with limiting an individual's freedom of movement, has become a focal point of extensive discussion and evaluation within the realm of mental healthcare. Striking a delicate balance between ensuring individual safety and minimizing reliance on restraint methods poses a significant challenge. In mental health inpatient settings, the prevalent forms of restraint encompass physical, chemical, environmental, and psychological methods. Paradoxically, the consequences of employing restraint can be severe, ranging from injuries and cognitive decline to sedation and, in extreme cases, fatalities. This paper seeks to offer a nuanced exploration of the landscape surrounding psychiatric patient restraints, considering both global perspectives and specific insights from the Indian context. The guidelines outlined in India's Mental Healthcare Act of 2017, which governs the use of restraint on individuals suffering with mental illnesses, are also examined in detail.

Mechanical Restraint in Inpatient Psychiatric Unit: Prevalence and Associated Clinical Variables

Background and Objectives: mechanical restraint (MR) is a controversial issue in emergency psychiatry and should be better studied to implement other alternative therapeutic interventions. The aim of this study was to estimate the prevalence of MR in an Italian psychiatric unit and identify the sociodemographic and clinical characteristics as well as the pharmacological pattern associated with MR. Materials and Methods: all subjects (N = 799) consecutively admitted to an Italian psychiatric inpatient unit were recruited. Several sociodemographic and clinical characteristics were recorded. Results: The prevalence of MR was 14.1%. Males, a younger age, and a single and migrant status were associated with the MR phenomenon. MR was more prevalent in patients affected by other diagnoses and comorbid illicit substance use, in patients with aggressive behaviors, and those that were involuntary admitted, leading significantly to hospitalization over 21 days. Furthermore, the patients that underwent MR were taking a lower number of psychiatric medications. Conclusions: Unfortunately, MR is still used in emergency psychiatry. Future research should focus on the dynamics of MR development in psychiatry, specifically considering ward- and staff-related factors that could help identify a more precise prevention and alternative intervention strategies.

Design and Implementation of an Agitation Code Response Team in the Emergency Department

STUDY OBJECTIVE

Agitation, defined as excessive psychomotor activity leading to violent and aggressive behavior, is becoming more prevalent in the emergency department (ED) amidst a strained behavioral health system. Team-based interventions have demonstrated promise in promoting de-escalation, with the hope of minimizing the need for invasive techniques, like physical restraints. This study aimed to evaluate an interprofessional code response team intervention to manage agitation in the ED with the goal of decreasing physical restraint use.

METHODS

This quality improvement study occurred over 3 phases, representing stepwise rollout of the intervention: (1) preimplementation (phase I) to establish baseline outcome rates; (2) design and administrative support (phase II) to conduct training and protocol design; and (3) implementation (phase III) of the code response team. An interrupted time-series analysis was used to compare trends between phases to evaluate the primary outcome of physical restraint orders occurring during the study period.

RESULTS

Within the 634,578 ED visits over a 5-year period, restraint use significantly declined sequentially over the 3 phases (1.1%, 0.9%, and 0.8%, absolute change -0.3% between phases I and III, 95% confidence interval [CI] -0.4% to 0.3%), which corresponded to a 27.3% proportionate decrease in restraint rates between phases I and III. For the interrupted time-series analysis, there was a significantly decreasing slope in biweekly restraints in phase II compared to phase I (slope, -0.05 restraints per 1,000 ED visits per 2-week period, 95% CI -0.07 to -0.03), which was sustained in an incremental fashion in phase III (slope, -0.05, 95% CI -0.07 to -0.02).

CONCLUSION

With the implementation of a structured agitation code response team intervention combined with design and administrative support, a decreased rate of physical restraint use occurred over a 5-year period. Results suggest that investment in organizational change, along with interprofessional collaboration during the management of agitated patients in the ED, can lead to sustained reductions in the use of an invasive and potentially harmful measure on patients.

Safety and efficacy of pharmacologic agents used for rapid tranquilization of emergency department patients with acute agitation or excited delirium

Introduction: Management of patients with acute agitation or aggressive behavior can pose a significant challenge to health-care providers in emergency departments. Areas covered: This article provides a comprehensive review of the pharmacologic properties, efficacy, and safety profiles of select intramuscular (IM) sedative agents (i.e., antipsychotics, benzodiazepines, and ketamine) for rapid tranquilization. Expert opinion: Using antipsychotics and benzodiazepines - whether a single agent or combined - will have similar efficacy in producing sedation. But there are differences in the time to sedation depending on which agent is used. Based upon the available studies, droperidol (5-10 mg IM) and midazolam (5-10 mg IM) have the fastest onset of sedation when either is used as a single agent. When combination therapy is used, using midazolam with an antipsychotic agent, instead of lorazepam, may result in faster sedative effect. QT prolongation and torsades de pointes are uncommon adverse drug effects of antipsychotic administration. Ketamine is often reserved as a second-line agent when antipsychotics and benzodiazepines fail to produce the desired tranquilization. However, ketamine (5 mg/kg IM) is more frequently associated with airway compromise requiring endotracheal intubation. A low-dose of ketamine (2 mg/kg IM) may reduce the risk of airway compromise while providing adequate sedation.

Violence in the Emergency Department: A Global Problem

Violence against health care workers is an unfortunately common event. Because of several inherent factors, emergency departments are particularly vulnerable. Once an incident occurs, it often goes unreported and leads to both physical and mental trauma. Health care workers should learn to recognize the cues that patients are escalating toward violence and be familiar with various options for sedating agitated patients. If sedation is not successful, physical restraint may become necessary. There are measures that can be taken that may help minimize the likelihood of violence toward health care workers. These measures include legislation, physical design, and increased security.

Unrecognized hypoxia and respiratory depression in emergency department patients sedated for psychomotor agitation: pilot study

INTRODUCTION

The incidence of respiratory depression in patients who are chemically sedated in the emergency department (ED) is not well understood. As the drugs used for chemical restraint are respiratory depressants, improving respiratory monitoring practice in the ED may be warranted. The objective of this study is to describe the incidence of respiratory depression in patients chemically sedated for violent behavior and psychomotor agitation in the ED.

METHODS

Adult patients who met eligibility criteria with psychomotor agitation and violent behavior who were chemically sedated were eligible. SpO2 and ETCO2 (end-tidal CO2) was recorded and saved every 5 seconds. Demographic data, history of drug or alcohol abuse, medical and psychiatric history, HR and BP every 5 minutes, any physician intervention for hypoxia or respiratory depression, or adverse events were also recorded. We defined respiratory depression as an ETCO2 of ≥50 mmHg, a change of 10% above or below baseline, or a loss of waveform for ≥15 seconds. Hypoxia was defined as a SpO2 of ≤93% for ≥15 seconds.

RESULTS

We enrolled 59 patients, and excluded 9 because of ≥35% data loss. Twenty-eight (28/50) patients developed respiratory depression at least once during their chemical restraint (56%, 95% CI 42-69%); the median number of events was 2 (range 1-6). Twenty-one (21/50) patients had at least one hypoxic event during their chemical restraint (42%, 95% CI 29-55%); the median number of events was 2 (range 1-5). Nineteen (19/21) (90%, 95% CI 71-97%) of the patients that developed hypoxia had a corresponding ETCO2 change. Fifteen (15/19) (79%, 95% CI 56-91%) patients who became hypoxic met criteria for respiratory depression before the onset of hypoxia. The sensitivity of ETCO2 to predict the onset of a hypoxic event was 90.48% (95% CI: 68-98%) and specificity 69% (95% CI: 49-84%). Five patients received respiratory interventions from the healthcare team to improve respiration [Airway repositioning: (2), Verbal stimulation: (3)]. Thirty-seven patients had a history of concurrent drug or alcohol abuse and 24 had a concurrent psychiatric history. None of these patients had a major adverse event.

CONCLUSION

About half of the patients in this study exhibited respiratory depression. Many of these patients went on to have a hypoxic event, and most of the incidences of hypoxia were preceded by respiratory depression. Few of these events were recognized by their treating physicians.

Association between combative behavior requiring intervention and delirium in hospitalized patients

BACKGROUND

We hypothesized that delirium contributes to combative behavior requiring intervention in hospitalized patients. Delirium identification would therefore potentially provide an opportunity for prevention and early identification of patients at risk, thereby improving safety for patients and staff.

OBJECTIVE

To determine whether delirium is associated with combative behavior requiring intervention in a general hospital population.

DESIGN

Case control study.

SETTING

A 336-bed, nonuniversity, teaching hospital serving adults in the Pacific Northwest.

PATIENTS

One hundred twenty consecutive hospitalized patients with combative behavior requiring intervention compared to 159 randomly selected inpatient control subjects, all from 2011.

INTERVENTION

Bivariate statistics were used to compare demographics; diagnoses; presence of delirium, dementia, substance use, other psychiatric diagnosis; medications; hospital length of stay; and discharge disposition. We used stepwise logistic regression to determine the association of combative behavior requiring intervention with delirium after adjustment for covariates.

RESULTS

Delirium preceding the combative behavior was present in 50% (60/120) of patients with combative behavior requiring intervention compared to 16% (26/159) of controls (P < 0.001). Combative-behavior patients were hospitalized longer (9.4 vs 4.5 days, P < 0.001), and were more likely to be discharged to a skilled nursing facility (26%, 31/120) or to leave against medical advice (10%, 12/120, P < 0.001). Delirium was strongly associated with combative behavior requiring intervention, after adjustment (odds ratio: 3.8, 95% confidence interval: 2.0-7.3, P < 0.001).

CONCLUSION

Delirium is strongly associated with combative behavior requiring intervention, which poses a significant safety risk for patients and staff.

Pharmacologic management of the agitated child

Agitation is a chief complaint that causes many children and adolescents to present to emergency medical attention. There are many reasons for acute agitation, including toxicologic, neurologic, infectious, metabolic, and functional disorders. At times it may be necessary to pharmacologically treat the agitation to prevent harm to the patient, caregivers, or hospital staff. However, one should always be mindful that the differential diagnosis is broad, and a complete although timely assessment with targeted testing must be done before concluding that the agitation is rooted solely in nonorganic causes. There are various pharmacologic choices for the treatment of agitation, and they will be reviewed here. While treatment of agitation may be necessary to keep the patient as well as staff safe, as well as to facilitate medical evaluation in some cases, care must be taken to treat the patient with compassion, never using pharmacologic treatment for reasons of punishment or staff convenience. The focus is on the pharmacologic management of acute agitation of patients in the pediatric age group, in the context of a full evaluation for possible nonfunctional causes of agitation. Goals, risks, and benefits of medication use will be reviewed.

Early detection of risk factors for seclusion and restraint: a prospective study

AIM

The study aims to examine the predictive power of static and dynamic risk factors assessed at admission to an acute psychiatric ward and to develop a prediction model evaluating the risk of seclusion and restraint.

METHODS

Over 20 months, data on demographic and clinical characteristics, psychosocial functioning, level of insight, uncooperativeness, and use of coercive measures were collected prospectively on 520 patients at admission. Logistic regression analysis was used to develop a prediction model. The magnitude of the predictive power of this model was estimated using receiver operating characteristic analysis.

RESULTS

The prediction model contained one static predictor (involuntary commitment) and two dynamic predictors (psychological impairment and uncooperativeness), with a high predictive power (receiver operating characteristic area under the curve = 0.83). The final risk model classified 72% of the patients correctly, with a higher sensitivity rate (80%) than specificity rate (71%).

CONCLUSION

Early assessment of patients' psychological impairment and uncooperativeness can help clinicians to recognize patients at risk for coercive measures and approach them on time with preventive and less restrictive interventions. Although this simple, highly predictive model accurately predicts the risk of seclusion or restraint, further validation studies are needed before it can be adopted into routine clinical practice.

Pitfalls in the care of the psychiatric patient in the emergency department

BACKGROUND

Care of the psychiatric patient in the Emergency Department (ED) is evolving. As with other disease states, there are a number of pitfalls that complicate the care of the psychiatric patient.

OBJECTIVE

The purpose of this article is to update Emergency Physicians concerning the pitfalls in caring for the psychiatric patient, and possible solutions to deal with these pitfalls.

DISCUSSION

The article will address the burden of the psychiatric patient, staff attitudes, medical clearance process, treatment of the agitated patient, suicidal patients, and admission decisions.

CONCLUSIONS

Alternative care resources, collaboration with Psychiatry, staff education, improvement in the medical clearance process, proper use of restraint and seclusion, and appropriate choice of medication for agitated patients can help avoid some of the top pitfalls in the care of the psychiatric patient in the ED.

Patients' preference and experiences of forced medication and seclusion

This study examined patients' preferences for coercive methods and the extent to which patients' choices were determined by previous experience, demographic, clinical and intervention-setting variables. Before discharge from closed psychiatric units, 161 adult patients completed a questionnaire. The association between patients' preferences and the underlying variables was analyzed using logistic regression. We found that patients' preferences were mainly defined by earlier experiences: patients without coercive experiences or who had had experienced seclusion and forced medication, favoured forced medication. Those who had been secluded preferred seclusion in future emergencies, but only if they approved its duration. This suggests that seclusion, if it does not last too long, does not have to be abandoned from psychiatric practices. In an emergency, however, most patients prefer to be medicated. Our findings show that patients' preferences cannot guide the establishment of international uniform methods for managing violent behaviour. Therefore patients' individual choices should be considered.
