The Violence Prevention Community Meeting: A Multi-Site Study

Randomized controlled trials of mental health nurse-delivered interventions: A systematic review

WHAT IS KNOWN ON THE SUBJECT?: Well conducted randomized controlled trials provide the highest level of evidence of effectiveness of healthcare interventions, including those delivered by mental health nurses. Trials have been conducted over the years but there has not been a comprehensive review since 2005, and never one including studies conducted outside the UK. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: The paper provides a comprehensive overview of results from randomized controlled trials of mental health nurse-delivered interventions conducted in the UK, Ireland, US, Australia, New Zealand, or Canada and reported 2005 to 2020. It highlights that the trial evidence is limited and offers only partial evidence for interventions that are central to mental health nursing practice. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Much mental health nursing practice is not supported by the highest level trial evidence. Mental health nurses need to carefully select evidence on which to base their practice both from the mental health nursing literature and beyond. Mental health nurses and other stakeholders should demand greater investment in trials to strengthen the evidence base.

ABSTRACT

INTRODUCTION: Nurses are the largest professional disciplinary group working in mental health services and have been involved in numerous trials of nursing-specific and multidisciplinary interventions. Systematic appraisal of relevant research findings is rare.

AIM

To review trials from the core Anglosphere (UK, US, Canada, Ireland, Australia, New Zealand) published from 2005 to 2020.

METHOD

A systematic review reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses. Comprehensive electronic database searches were conducted. Eligible studies were randomized controlled trials of mental health nurse-delivered interventions conducted in relevant countries. The risk of bias was independently assessed. Synthesis involved integration of descriptive statistics of standardized metrics and study bias.

RESULTS

Outcomes from 348 between-group comparisons were extracted from K = 51 studies (N = 11,266 participants), Standardized effect sizes for 68 (39 very small/small, 29 moderate/large) statistically significant outcomes from 30 studies were calculable. All moderate/large effect sizes were at risk of bias.

DISCUSSION

Trial evidence of effective mental health nurse-delivered interventions is limited. Many studies produced few or no measurable benefits; none demonstrated improvements related to personal recovery.

IMPLICATIONS FOR PRACTICE

Mental health nurses should look beyond gold standard RCT evidence, and to evidence-based interventions that have not been trialled with mental health nurse delivery.

Instruments for Measuring Violence on Acute Inpatient Psychiatric Units: Review and Recommendations

OBJECTIVE

Violence by patients against inpatient psychiatric unit staff is common, causing considerable suffering. Despite the Joint Commission's 2018 requirement for behavioral health organizations to use standardized instruments, no identified gold standard measures of violence and aggression exist. Therefore, accurate data are lacking on the frequency of patient-to-staff violence to guide development of safer institutional clinical policies or to assess the impact of targeted interventions to reduce violence. To inform recommendations for developing standardized scales, the authors reviewed the scoring instruments most commonly used to measure violence in recent studies.

METHODS

A comprehensive literature search for violence measurement instruments in articles published in English from June 2008 to June 2018 was performed. Review criteria included use of instruments measuring patient-to-staff violence or aggression in acute, nonforensic, nongeriatric populations. Exclusion criteria included child or adolescent populations, staff-to-staff violence, and staff- or visitor-to-patient violence.

RESULTS

Overall, 74 studies were identified, of which 74% used structured instruments to measure aggression and violence on inpatient psychiatric units during the past 10 years. The instruments were primarily variants of the Observed Aggression Scale (OAS); 26% of the studies used unstructured clinical notes and researcher questionnaires. Major obstacles to implementing measurement instruments included time and workflow constraints and difficulties with use.

CONCLUSIONS

In the past 10 years, OAS variants with evidence of validity and reliability that define aggression and violence have been consistently used. The authors propose that adapting the Modified OAS to collect real-time clinical data could help overcome barriers to implementing standardized instruments to quantify violence against psychiatric staff.

Patient safety in inpatient mental health settings: a systematic review

OBJECTIVES

Patients in inpatient mental health settings face similar risks (eg, medication errors) to those in other areas of healthcare. In addition, some unsafe behaviours associated with serious mental health problems (eg, self-harm), and the measures taken to address these (eg, restraint), may result in further risks to patient safety. The objective of this review is to identify and synthesise the literature on patient safety within inpatient mental health settings using robust systematic methodology.

DESIGN

Systematic review and meta-synthesis. Embase, Cumulative Index to Nursing and Allied Health Literature, Health Management Information Consortium, MEDLINE, PsycINFO and Web of Science were systematically searched from 1999 to 2019. Search terms were related to 'mental health', 'patient safety', 'inpatient setting' and 'research'. Study quality was assessed using the Hawker checklist. Data were extracted and grouped based on study focus and outcome. Safety incidents were meta-analysed where possible using a random-effects model.

RESULTS

Of the 57 637 article titles and abstracts, 364 met inclusion criteria. Included publications came from 31 countries and included data from over 150 000 participants. Study quality varied and statistical heterogeneity was high. Ten research categories were identified: interpersonal violence, coercive interventions, safety culture, harm to self, safety of the physical environment, medication safety, unauthorised leave, clinical decision making, falls and infection prevention and control.

CONCLUSIONS

Patient safety in inpatient mental health settings is under-researched in comparison to other non-mental health inpatient settings. Findings demonstrate that inpatient mental health settings pose unique challenges for patient safety, which require investment in research, policy development, and translation into clinical practice.

Validation of the Assault (Violence) Response Scale: An Update

Background and Purpose

The Assault (Violence) Response Questionnaire has been used widely in the United States, Europe, Asia, and Africa since the 1980s. The purpose is to update the ARQ.

Method

Specifically the ARQ-R has been expanded to include verbal assault and withholding information, more extensively tested for reliability and validity, and shortened.

Results

The scale was reduced from 88 to 33 items and yet had the same high reliability and validity as did the larger scale.

Conclusions

The reduction in size makes it much less time consuming to complete, making it an instrument that very busy nurses can more easily use. The ARQ-R can be used for nurses measuring assault in both hospital and community settings.

Violence Prevention Community Meeting Conducted on Your Unit

The Violence Prevention Community Meeting (VPCM) is to reduce violence on inpatient psychiatry units, and has been written about elsewhere. The purpose of this article is to explain how other nurses can implement a similar meeting in their work setting. Details of different aspects of the VPCM are provided including the purpose, administrative support role of patients and staff, and the content and process of the VPCM. The reader is presented with several different scenarios about assault. The VPCM is an innovative, group-based treatment, administered by nursing staff members. Goals of the VPCM are to promote a shared culture of safety and respect among patients and nursing staff, and freedom for patients and staff from being targets, perpetrators, or witnesses of verbal or physical violence.
