Workplace characteristics of forensic and nonforensic psychiatric units associated with posttraumatic stress disorder (PTSD) symptoms

Exploring work-related stressors experienced by mental health nurses: A qualitative descriptive study

INTRODUCTION

The challenging work environments mental health nurses (MHNs) encounter can negatively impact their mental health, psychological well-being and physical health. While these impacts have been investigated in quantitative research, little is known about work-related stress from the perspective of MHNs.

AIM

To explore the stresses faced by nurses working in mental health settings and to gain an understanding of the underlying workplace context.

METHOD

A descriptive qualitative study with data collected via semi-structured individual telephone interviews conducted with n = 21 Western Australian MHNs. Data were analysed using reflexive thematic analysis.

RESULTS

A total of 85 codes were generated that led to the identification of 13 subthemes and 4 main themes: (1) mental health nursing context, (2) work environment stressors, (3) factors that alleviate stress and (4) the impact of workplace stress.

DISCUSSION

Many of the stressors MHNs were exposed to are modifiable, such as understaffing and poor skill mix. Modifiable stressors increased risk for MHNs, impeded patient care and exacerbated inherent stressors such as patient acuity and complexity.

IMPLICATIONS FOR PRACTICE

This study collected data that provide rich descriptions of the experiences of MHNs and identify modifiable work-related stressors that could be alleviated through effective leadership and management.

Novel pathogenesis of post-traumatic stress disorder studied in transgenic mice

Posttraumatic stress disorder (PTSD) is very common after exposure to trauma, mental stress or violence. Because objective biological markers for PTSD are lacking, exactly diagnosing PTSD is a challenge for clinical psychologists. In-depth research on the pathogenesis of PTSD is a key for solving this problem. In this work, we used male Thy1-YFP transgenic mice, in which neurons are fluorescently labeled, to research the effects of PTSD on neurons in vivo. We initially discovered that pathological stress associated with PTSD increased the activation of glycogen synthesis kinase-beta (GSK-3β) in neurons and induced the translocation of the transcription factor forkhead box-class O3a (FoxO3a) from the cytoplasm to the nucleus, which decreased the expression of uncoupling protein 2 (UCP2) and increased mitochondrial production of reactive oxygen species (ROS) to trigger neuronal apoptosis in the prefrontal cortex (PFC). Furthermore, the PTSD model mice showed increased freezing and anxiety-like behaviors and more severe decrease of memory and exploratory behavior. Additionally, leptin attenuated neuronal apoptosis by increasing the phosphorylation of signal transducer and activator of transcription 3 (STAT3), which further elevated the expression of UCP2 and inhibited the mitochondrial production of ROS induced by PTSD, thus reducing neuronal apoptosis and ameliorating PTSD-related behaviors. Our study is expected to promote the exploration of PTSD-related pathogenesis in neural cells and the clinical effectiveness of leptin for PTSD.

Workplace stressors and PTSD among psychiatric workers: The mediating role of burnout

Critical workplace events (e.g., assaults), chronic stressors, burnout, and work conditions all affect nurse well-being. The present study investigated associations among these sources of stress and posttraumatic stress disorder (PTSD) symptoms in psychiatric nurses, hypothesizing that burnout would mediate the paths between workplace stressors and PTSD. Surveys were completed by 611 psychiatric nurses or allied health staff working on inpatient units in three psychiatric hospitals. Participants reported on critical events and chronic stressors specific to providing psychiatric care and completed the Maslach Burnout Inventory (MBI), Areas of Worklife Survey (AWS) (work conditions), and PTSD Checklist for DSM-5. Data were analysed using structural equation modelling. Burnout had a direct relation to PTSD symptoms and partially mediated the effect of exposure to critical events, but not chronic stressors, on PTSD symptoms. Chronic stressors related to patients' disturbing behaviour (e.g., flooding room, eating non-food items) had a direct effect on PTSD symptoms, but those related to resisting care (e.g., screaming constantly, physically resisting care) had no significant association. Worklife conditions had a negative direct effect on Burnout and indirect effect on PTSD, whereby participants reporting poorer alignment of work conditions with their expectations had higher Burnout and PTSD symptom scores. Different sources of workplace stress have different relations to PTSD symptoms, and Burnout has both direct and mediation effects. Interventions aimed at reducing patients' aggressive and disturbing acts and improving healthcare providers' burnout and worklife factors in hospitals may all be needed to reduce PTSD among psychiatric staff.

Workplace violence and risk factors for PTSD among psychiatric nurses: Systematic review and directions for future research and practice

WHAT IS KNOWN ON THE SUBJECT?: Trauma among psychiatric nurses and other healthcare workers is related to workplace violence, but other risk factors may also contribute, including those occurring before, during or after workplace violence. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: Most previously identified PTSD risk factors were not tested or supported in research with psychiatric nurses, although there is promising evidence for risk factors including severe or injurious assault, cumulative exposure, burnout, and other worker characteristics. We identify directions for research needed to improve knowledge, including collecting data before nurses experience workplace violence, defining workplace risk factors consistently and conducting and reporting qualitative analysis. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Provide training in risk assessment and violence prevention to psychiatric nurses. Offer mental health support to those exposed to violence, especially with cumulative exposure. ABSTRACT: Introduction Psychiatric nurses are at risk of workplace violence and post-traumatic stress disorder (PTSD). There is limited understanding of pre-trauma and post-trauma risk factors. Aim Our aim was to review factors associated with workplace PTSD in psychiatric nurses. Method We searched quantitative and qualitative studies from 1980 to 2019 in 23 databases plus abstracts for studies on psychiatric hospital nursing staff, potentially traumatic workplace events, workplace factors and PTSD. Following duplicate abstract (n = 10,064) and full-text (n = 199) screening, data were extracted in duplicate from 19 studies. Using best-fit framework synthesis, we identified workplace violence, pre-trauma and post-trauma risk factors. Results Six variables yielded evidence in at least two empirical studies scoring at least 6/8 on a quality measure, or one such study plus more than one other study ("promising": severe/injurious assault, cumulative exposure, burnout, poor mental health, low compassion satisfaction, neuroticism). Four were supported by at least one better quality study or at least two others ("suggestive": gender, poor training, any physical aggression exposure, compassion fatigue). Discussion Pre-trauma measures, consistent definitions of workplace exposures and thorough reporting of quantitative results are needed to improve research. Implications for Practice Violence prevention and mental health care for exposed nurses appear the most promising targets for PTSD prevention. Therefore, it is particularly important to understand workplace violence and mental health among nurses working in psychiatric hospitals.

Workplace interventions to prevent or reduce post-traumatic stress disorder and symptoms among hospital nurses: A scoping review

OBJECTIVES

The aim of this study was to identify literature on evaluated workplace interventions to prevent or reduce the prevalence or impact of work-related post-traumatic stress disorder (PTSD) and PTSD symptoms among hospital nurses. A second objective was to summarise and compare the characteristics and effectiveness of these interventions.

BACKGROUND

A substantial proportion of nurses report PTSD symptoms. Previous reviews have synthesised interventions to address PTSD in military and other high-risk populations, but similar work focusing on nurses has yet to be conducted.

METHODS

We conducted a scoping review with the question: What interventions have been studied to prevent or treat PTSD symptoms or PTSD among nurses working in hospitals? We followed the PRISMA Scoping Review Checklist using an unregistered protocol. We searched in twelve academic and grey literature databases (e.g. MedLine, CINAHL) with no language restrictions. We included publications reporting on interventions which were evaluated for measurable impacts on PTSD and PTSD symptoms among nursing staff working in inpatient settings from 1980 to 2019, and charted study characteristics in a spreadsheet.

RESULTS

From 7746 results, 63 studies moved to full-text screening, and six studies met inclusion criteria. Methodologies included three randomised controlled studies, one quasi-experimental study, one pre-post feasibility study and one descriptive correlational study. Four studies reported a significant reduction in PTSD scores in intervention groups compared with baseline or comparison, when using debriefing, guided imagery or mindfulness-based exercises.

CONCLUSIONS

This review identified six studies evaluating hospital-based interventions to reduce PTSD and PTSD symptoms among hospital nurses, with some positive effects reported, contributing to a preliminary evidence base on reducing workplace trauma. Larger studies can compare nurse subpopulations, and system-level interventions should expand the focus from individuals to organisations.

RELEVANCE TO CLINICAL PRACTICE

This review can inform nursing and hospital leaders developing evidence-based interventions for PTSD among nurses.

Perceptions of Workplace Violence and Workplace Stress: A Mixed Methods Study of Trauma among Psychiatric Workers

Posttraumatic stress disorder (PTSD) among psychiatric workers is related to workplace violence and work-specific stress. We used quantitative and qualitative approaches to survey PTSD symptoms, critical events, chronic exposures, and occupational stress in 84 psychiatric workers. All but three had directly experienced critical events, over half experienced someone's life being in danger, and 14% screened positive for PTSD. Symptoms correlated with critical events and perceived threat to life. Respondents described emergency codes, direct involvement, and repeated exposure as most stressful. Symptoms also correlated with nonviolent stressors, replicating previous research and indicating need to reduce both violence and workplace stress.

Mental health workers' experiences of support and help-seeking following workplace violence: A qualitative study

The consequences of workplace trauma among mental health staff can include physical injuries and somatic disorders, professional exhaustion and burnout, depression, anxiety, and other occupational stress injuries. For the well-being of staff and patients, there is a need to understand mental health workers' experiences following exposure to workplace trauma, any subsequent mental health problems, and the process of help-seeking. The nuances of these experiences can best be captured through qualitative exploration. In this study, we explored inpatient mental health workers' experiences of support and help-seeking following workplace violence. Four overall themes emerged from interviews with 12 participants: (i) validation as motivation for help-seeking; (ii) stigma as a barrier to help-seeking; (iii) gaps in services provided; and (iv) desire for accessible and effective trauma support and education. This study demonstrates the need for supportive management responses and peer support, access to specialized and confidential trauma-informed mental health services, and reductions in stigma, victim blaming, and other barriers to help-seeking among mental health workers.

A Systematic Review of Job Demands and Resources Associated with Compassion Fatigue in Mental Health Professionals

Psychosocial hazards in mental healthcare contribute to the development of compassion fatigue in mental health professionals. Compassion fatigue has a negative impact on the mental health and wellbeing of professionals that can impair the quality of services provided to clients. The majority of research on compassion fatigue has focused on individual-level variables such as gender, history of trauma and age, among others. It is also imperative to understand the role played by alterable work-related characteristics in contributing to the development of compassion fatigue in order to attenuate its impact on mental health professionals and their clients. The present review examined articles exploring work-related factors associated with compassion fatigue. Fifteen quantitative studies were included and their quality was assessed using a checklist. An inductive content-analysis approach was adopted to synthesise the themes emerging from the data. The results suggested a theoretical model consistent with the Job Demands-Resources model, wherein job demands (such as workplace trauma, workload and therapeutic settings) are associated with compassion fatigue, and job resources (such as supervisors', coworkers' and organisational support) mitigate the impact of job demands. In addition to person-oriented factors, work-related factors are critical for the prevention of compassion fatigue.

Short-term clinical risk assessment and management: Comparing the Brockville Risk Checklist and Hamilton Anatomy of Risk Management

The current article aims to examine the performance of two brief, dynamic risk measures - the Brockville Risk Checklist (BRC4) and one of two versions of the Hamilton Anatomy of Risk Management [HARM-FV and electronic HARM-FV (eHARM-FV)] - scored at regular clinical case conferences for forensic psychiatric patients in two different settings. The eHARM represents a first-in-class dynamic risk assessment tool using data analytics. Two studies are presented from two forensic psychiatric hospitals in Ontario, Canada. The first study compared the HARM-FV, scored by trained research staff, with the BRC4, scored concurrently by clinical teams, on 36 forensic inpatients. In the second study, trained research staff scored both the BRC4 and the eHARM-FV on 55 forensic inpatients. Both studies demonstrated that the BRC4 and both HARM-FV tools were moderately and positively correlated with each other, with higher agreement for similar domains and items. In both samples, the risk measures performed better at identifying individuals who engaged in repeated or more serious problematic behavior. The HARM-FV and eHARM-FV produced higher area under the curve values for subsequent behavior compared with the BRC4. All three tools were effective at detecting future aggression and adverse incidents. We did not directly compare the HARM-FV and eHARM-FV.
