A review of the literature on positional asphyxia as a possible cause of sudden death during restraint

A regional multicomponent intervention for mechanical restraint reduction in acute psychiatric wards

WHAT IS KNOWN ON THE SUBJECT?: A relevant number of restraint prevention programmes have been developed internationally. In Spain, there is no harmonized policy to prevent the use of restraint. More studies are necessary to establish which programmes and components are necessary to prevent restraint. WHAT DOES THE PAPER ADD TO EXISTING KNOWLEDGE?: There was a significant decreasing trend in the total number of mechanical restraint hours during the implementation of the intervention. There was no significant decreasing trend in the number of mechanical restraint episodes. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Interventions at a regional level aimed at preventing mechanical restraint are feasible in the Spanish context. All components of the Six Core Strategies could be necessary to prevent episodes of mechanical restraint. ABSTRACT: Introduction Mechanical restraint (MR) is used in many countries, including Spain, where non-harmonized policies between autonomous communities exist. There is a lack of research about interventions at regional levels to reduce their use. Aim To analyse data on key outcomes during the implementation of a multicomponent intervention in Andalusia (Spain) to reduce the use of MR. Method Episodes in a period of 30 months in all wards (N = 20) were analysed. The intervention consisted of five strategies: (a) leadership, (b) analysis of the situation, (c) awareness training for the heads of the wards, (d) unified record of MR and (e) staff training. We analysed the monthly trend of restraint hours and restraint episodes/1,000 bed days using segmented regression. Results There were 206.32 restraint hours and 12.96 restraint episodes/1,000 bed days during the study period. A significant decreasing trend was observed in restraint hours (-1.79%, p < .001), but not in the number of restraint episodes (-0.45%; p = .149). Discussion The results coincide with other international studies; however, studies with better designs are required to evaluate the effectiveness of the intervention. Implications for Practice Interventions at a regional level aimed at preventing MR are feasible in the Spanish context.

An integrative review exploring the physical and psychological harm inherent in using restraint in mental health inpatient settings

In Western society, policy and legislation seeks to minimize restrictive interventions, including physical restraint; yet research suggests the use of such practices continues to raise concerns. Whilst international agreement has sought to define physical restraint, diversity in the way in which countries use restraint remains disparate. Research to date has reported on statistics regarding restraint, how and why it is used, and staff and service user perspectives about its use. However, there is limited evidence directly exploring the physical and psychological harm restraint may cause to people being cared for within mental health inpatient settings. This study reports on an integrative review of the literature exploring available evidence regarding the physical and psychological impact of restraint. The review included both experimental and nonexperimental research papers, using Cooper's (1998) five-stage approach to synthesize the findings. Eight themes emerged: Trauma/retraumatization; Distress; Fear; Feeling ignored; Control; Power; Calm; and Dehumanizing conditions. In conclusion, whilst further research is required regarding the physical and psychological implications of physical restraint in mental health settings, mental health nurses are in a prime position to use their skills and knowledge to address the issues identified to eradicate the use of restraint and better meet the needs of those experiencing mental illness.

Excited Delirium: A Systematic Review

OBJECTIVE

We aimed to clarify the definition, epidemiology, and pathophysiology of excited delirium syndrome (ExDS) and to summarize evidence-based treatment recommendations.

METHODS

We conducted a systematic literature search of MEDLINE, Ovid, Web of Knowledge, and Cochrane Library for articles published to March 18, 2017. We also searched the gray literature (Google Scholar) and official police or medical expert reports to complete specific epidemiologic data. Search results and full-text articles were independently assessed by two investigators and agreements between reviewers assessed with K statistics. We classified articles by study type, setting, and evidence level.

RESULTS

After reviewing the title and abstract of 3,604 references, we fully reviewed 284 potentially relevant references, from which 66 were selected for final review. Six contributed to the definition of ExDS, 24 to its epidemiology, 38 to its pathophysiology, and 27 to its management. The incidence of ExDS varies widely with medical or medicolegal context. Mortality is estimated to be as much as 8.3% to 16.5%. Patients are predominantly male. Male sex, young age, African-American race, and being overweight are independent risk factors. Pathophysiology hypotheses mostly implicate dopaminergic pathways. Most cases occur with psychostimulant use or among psychiatric patients or both. Proposed treatments are symptomatic, often with rapid sedation with benzodiazepines or antipsychotic agents. Ketamine is suggested as an alternative.

CONCLUSION

The overall quality of studies was poor. A universally recognized definition is lacking, remaining mostly syndromic and based on clinical subjective criteria. High mortality rate may be due to definition inconsistency and reporting bias. Our results suggest that ExDS is a real clinical entity that still kills people and that has probably specific mechanisms and risk factors. No comparative study has been performed to conclude whether one treatment approach is preferable to another in the case of ExDS.

Clinical and organizational factors related to the reduction of mechanical restraint application in an acute ward: an 8-year retrospective analysis

Background:

The purpose of this study was to describe the frequency of mechanical restraint use in an acute psychiatric ward and to analyze which variables may have significantly influenced the use of this procedure. Methods: This retrospective study was conducted in the Servizio Psichiatrico di Diagnosi e Cura (SPDC) of Modena Centro. The following variables of our sample, represented by all restrained patients admitted from 1-1-2005 to 31-12-2012, were analyzed: age, gender, nationality, psychiatric diagnoses, organic comorbidity, state and duration of admission, motivation and duration of restraints, nursing shift and hospitalization day of restraint, number of patients admitted at the time of restraint and institutional changes during the observation period. The above variables were statistically compared with those of all other non-restrained patients admitted to our ward in the same period. Results: Mechanical restraints were primarily used as a safety procedure to manage aggressive behavior of male patients, during the first days of hospitalization and night shifts. Neurocognitive disorders, organic comorbidity, compulsory state and long duration of admission were statistically significantly related to the increase of restraint use (p<.001, multivariate logistic regression). Institutional changes, especially more restricted guidelines concerning restraint application, were statistically significantly related to restraint use reduction (p<.001, chi2 test, multivariate logistic regression). Conclusion: The data obtained highlight that mechanical restraint use was influenced not only by clinical factors, but mainly by staff and policy factors, which have permitted a gradual but significant reduction in the use of this procedure through a multidimensional approach.

Are physical intervention techniques likely to cause pain or injury when applied to manage the severely aggressive older adult? A survey of physiotherapist's expert views in the UK

AIM

To establish whether a professional consensus can be established amongst musculoskeletal physiotherapists or whether they believe certain physical intervention techniques would cause pain or injury if applied to an older adult.

BACKGROUND

Physiotherapist involvement in the context of a multidisciplinary team framework to develop adaptive techniques as required for complex physical presentations has resulted in lower injury rates than in working-age adults. Physiotherapists are experts in anatomy and human movement and are ideally placed to contribute to the safe application of physical intervention in older adults.

DESIGN

A survey design was used.

METHOD

A questionnaire was developed and tested to ascertain the physiotherapist's opinions of the likelihood of each technique causing the patient pain and/or injury. The lead author distributed 41 questionnaires to physiotherapists in two busy hospitals in the UK.

RESULTS

Thirty-four (83%) of physiotherapists returned the completed questionnaires. The physiotherapists had particular concerns about the use of wrist flexion and kneeling on the older adult in prone causing pain and/or injury. Some other techniques that we have advocated in our earlier research were approved by many of the respondents, e.g. supporting the forearm with both hands proximal to the wrist joint. None of the physiotherapists had attended a physical intervention course or applied it in the clinical setting, thus enabling them to analyse the techniques purely from a biomechanical movement perspective. Implications for nursing practice are discussed.

CONCLUSIONS

It is anticipated that this research will stimulate nurses and course providers to develop patient group-specific physical intervention techniques and thus reduce the risk of causing them pain and/or injury.

RELEVANCE TO CLINICAL PRACTICE

This study reaffirms the heightened risks associated with applying restraint techniques to older adults. An issue that needs to be addressed is whether the duty of care which is explicit and implicit within the relationship between nurse and patient is to be fully discharged. It also reinforces prior research that has called for patient-specific physical intervention techniques and highlights some commonly used techniques that may have a deleterious effect on aggressive older adults. It also identifies the professional support that physiotherapists can offer to teams implementing physical intervention techniques within the context of clinical practice.

Changing the practice of physical restraint use in acute care

Older adults are more likely to be restrained during hospital stays than are younger individuals. Use of physical restraints significantly undermines quality patient care and represents substandard care. Rather than using restraints, nursing staff should determine the source of the patient's behaviors through comprehensive assessment and try to detect patterns to move toward restraint-free care. This evidence-based practice guideline can be used to facilitate the recognition of older adults at risk for physical restraints use and the implementation of appropriate interventions to move toward restraint-free patient care. This, in turn, helps to maintain or promote older adults' quality of life.

Deaths associated with restraint use in health and social care in the UK. The results of a preliminary survey

Many aspects of the management of acutely disturbed behaviour have only relatively recently come under systematic scrutiny. Perhaps regrettably one of the last amongst the range of strategies that may be employed to be subjected to rigorous examination has been physical restraint. Considerable debate has recently taken place around what represents good practice in this sensitive and controversial area but the continuing dearth of research in some aspects of this area of practice has meant that this discussion has arguably been over reliant on 'expert' opinion. Questions continue regarding some fundamental issues of restraint, including the relative risks involved in alternative approaches, and anxieties have been expressed about the potential for injuries and death to result from restraint. This article outlines the results of a survey that sought to explore the incidence of deaths associated with restraint in health and social care settings in the UK. The outcome of an initial analysis of the cases identified is then discussed, with reference to the literature on restraint-related deaths, in order to identify the implications for practice.
