Work outcomes in public safety personnel after potentially traumatic events: A systematic review.

BACKGROUND: It is well documented that public safety personnel are exposed to potentially traumatic events (PTEs) at elevated frequency and demonstrate higher prevalence of trauma-related symptoms compared to the general population. Lesser studied to date are the organizational consequences of workplace PTE exposure and associated mental health outcomes such as acute/posttraumatic stress disorder (ASD/PTSD), depression, and anxiety. METHODS: The present review synthesizes international literature on work outcomes in public safety personnel (PSP) to explore whether and how PTE and trauma-related symptoms relate to workplace outcomes. A total of N = 55 eligible articles examining PTE or trauma-related symptoms in relation to work outcomes were systematically reviewed using best-evidence narrative synthesis. RESULTS: Three primary work outcomes emerged across the literature: absenteeism, productivity/performance, and costs to organization. Across n = 21 studies of absenteeism, there was strong evidence that PTE or trauma-related symptoms are associated with increased sickness absence. N = 27 studies on productivity/performance demonstrated overall strong evidence of negative impacts in the workplace. N = 7 studies on cost to organizations demonstrated weak evidence that PTE exposure or trauma-related mental health outcomes are associated with increased cost to organization. CONCLUSIONS: Based on available evidence, the experience of workplace PTE or trauma-related symptoms is associated with negative impact on PSP occupational functioning, though important potential confounds (e.g., organizational strain and individual risk factors) remain to be more extensively investigated.

Methodological correlates of variability in the prevalence of posttraumatic stress disorder in high-risk occupational groups: A systematic review and meta-regression.

BACKGROUND: Although numerous studies have reported on PTSD prevalence in high-risk occupational samples, previous meta-analytic work has been severely limited by the extreme variability in prevalence outcomes. METHODS: The present systematic review and meta-regression examined methodological sources of variability in PTSD outcomes across the literature on high-risk personnel with a specific focus on measurement tool selection. RESULTS: The pooled global prevalence of PTSD in high-risk personnel was 12.1% [6.5%, 23.5%], and was similar to estimates obtained in other meta-analytic work. However, meta-regression revealed that PTSD prevalence differed significantly as a function of measurement tool selection, study inclusion criteria related to previous traumatic exposure, sample size, and study quality. PTSD prevalence estimates also differed significantly by occupational group and over time, as has also been reported in previous work, though exploratory examination of trends in measurement selection across these factors suggests that measurement strategy may partially explain some of these previously reported differences. CONCLUSIONS: Our results highlight a pressing need to better understand the role of measurement strategies and other methodological choices in characterizing variable prevalence outcomes. Understanding the role of methodological variance will be critical for work attempting to reliably characterize prevalence as well as risk and protective factors for PTSD.

PREVALENCE AND PREDICTORS OF POSTTRAUMATIC STRESS DISORDER, DEPRESSION, AND ANXIETY IN PERSONNEL WORKING IN EMERGENCY DEPARTMENT SETTINGS: A SYSTEMATIC REVIEW.

BACKGROUND: Professionals working in the emergency department (ED) are regularly exposed to traumatic events. Rates of posttraumatic mental health conditions vary widely in the literature and there is no agreement that rates in ED staff are elevated relative to other populations. OBJECTIVE: We conducted a systematic review of international literature reporting prevalence of posttraumatic stress disorder (PTSD), depression, and anxiety in ED personnel to determine whether prevalence is elevated compared to the general community, and to evaluate convergent evidence across the literature for predictive factors. To our knowledge, there is no comprehensive review on this topic in the literature at this time. METHODS: Seven databases were searched for studies reporting rates of PTSD, depression, and anxiety in ED personnel. Two independent researchers screened studies and assessed quality using Munn's Prevalence Critical Appraisal Instrument. Best-evidence synthesis determined whether conditions demonstrated elevated prevalence compared to the general population of Canada, a conservative benchmark. RESULTS: Twenty-four studies from 12 countries and a combined sample size of 4768 were included. PTSD rates ranged from 0% to 23.6% (mean 10.47%), depression ranged from 0.7% to 77.1% (mean 24.8%), and anxiety rates ranged from 2.4% to 14.6% (mean 9.29%). Each condition was elevated compared to the general population. Sociodemographic variables were not consistent predictors. Elevated PTSD seemed most strongly related to workplace exposure and maladaptive coping. CONCLUSIONS: ED professionals have an elevated risk of experiencing PTSD, depression, and anxiety. Identification of organizational and workplace predictors are needed to inform interventions that will reduce risk and provide optimal treatment and management of PTSD, depression, and anxiety in ED settings.

The prevalence of PTSD, major depression and anxiety symptoms among high-risk public transportation workers.

OBJECTIVE: Public transportation workers are exposed to higher levels of stress related to accidents, injuries, and person-under-train events when compared to other workers. This systematic review integrates the existing literature on mental health among high-risk public transportation workers to estimate the prevalence of post-traumatic stress disorder (PTSD), major depressive and anxiety symptoms following critical incidents while on duty. METHODS: This systematic review is part of a larger systematic review which examines mental health and work outcomes of individuals working in professions at high risk of critical incident exposure, i.e., high-risk professions. Articles were included if they measured the prevalence of PTSD, Major Depressive Disorder (MDD) and Anxiety Disorder (AD) in a transportation population following exposure to a major incident, for example, a person-under-a-train. RESULTS: Among the ten articles, all reported prevalence of PTSD which ranged from 0.73 to 29.9%. Four articles reported prevalence of depression among transportation workers exposed to a critical incident and prevalence outcomes ranged from 0.05 to 16.3%. Only two reported prevalence of anxiety from 1.3 to 13.9%. CONCLUSIONS: This literature reports that transportation workers are prone to involvement in traumatic accidents leading to higher rates of PTSD compared to the general population. Strategies to reduce transportation accidents and to provide transportation workers follow-up mental health support is needed for this vulnerable population.

Mental Disorders in Firefighters Following Large-Scale Disaster.

Firefighting service is known to involve high rates of exposure to potentially traumatic situations, and research on mental health in firefighting populations is of critical importance in understanding the impact of occupational exposure. To date, the literature concerning prevalence of trauma-related mental disorders such as posttraumatic stress disorder (PTSD) has not distinguished between symptomology associated routine duty-related exposure and exposure to large-scale disaster. The present systematic review synthesizes a heterogeneous cross-national literature on large-scale disaster exposure in firefighters and provides support for the hypothesis that the prevalence of PTSD, major depressive disorder, and anxiety disorders are elevated in firefighters compared with rates observed in the general population. In addition, we conducted narrative synthesis concerning several commonly assessed predictive factors for disorder and found that sociodemographic factors appear to bear a weak relationship to mental disorder, while incident-related factors, such as severity and duration of disaster exposure, bear a stronger and more consistent relationship to the development of PTSD and depression in cross-national samples. Future work should expand on these preliminary findings to better understand the impact of disaster exposure in firefighting personnel.

Systematic review of posttraumatic stress disorder in police officers following routine work-related critical incident exposure.

BACKGROUND: The prevalence of PTSD in police officers has been the subject of a large and highly variable empirical literature. The present systematic review evaluates the extant literature on PTSD in police officers using an international dataset. METHODS: We employed best-evidence narrative synthesis to evaluate whether PTSD prevalence in police is elevated in comparison to the general population of Canada (8%), which itself has a higher lifetime PTSD prevalence than many other regions and thus serves as a conservative standard of comparison. RESULTS: PTSD prevalence in police varied considerably across studies from 0% - 44% (M = 14.87%, Median = 9.2%). Despite this variability, strong evidence exists to suggest PTSD prevalence is elevated in police officers. Examination of possible sources of variability in prevalence outcomes highlighted substantial variability in outcomes due to the selection of measurement tool for assessing PTSD (e.g., DSM vs. IES). Examination of commonly-assessed predictive factors for PTSD risk across the literature showed that individual-difference factors (e.g., age, years of service) bear weak-to-nonexistent relationships with PTSD risk, while incident-specific factors (e.g., severity of exposure) are more strongly and consistently associated with PTSD prevalence. Organizational factors (e.g., low support from supervisor) are at present understudied but important possible contributors to PTSD risk. CONCLUSIONS: PTSD prevalence is elevated in police officers and appears most strongly related to workplace exposure. Measurement variability remains a critical source of inconsistencies across the literature with drastic implications for accurate detection of officers in need of mental health intervention.

International employee perspectives on disability management.

PURPOSE: To provide an international analysis of employees' views of the influence of disability management (DM) on the workplace. METHODOLOGY: An international research team with representation from Australia, Canada, China, and Switzerland collected survey data from employees in public and private companies in their respective regions. Due to lack of availability of current measures, a research team-created survey was used and a total of 1201 respondents were collected across the four countries. ANALYSIS: Multiple linear (enter) regression was also employed to predict DM's influence on job satisfaction, physical health, mental health, workplace morale and reduced sickness absence, from respondents' perceptions of whether their company provided disability prevention, stay-at-work, and return-to-work initiatives within their organization. One-way ANOVA comparisons were used to examine differences on demographic variables including company status (public versus private), union status (union versus nonunion), and gender. RESULTS: The perceived influence of DM programs was related to perceptions of job satisfaction; whereas, relationships with mental health, physical health, morale, and sickness absence were variable according to type of DM program and whether the response was related to self or others. Difference analyses (ANOVA) revealed significantly more positive perceptions for private and nonunion organizations; no gender effects were found. CONCLUSIONS: There is perceived value of DM from the perspective of employees, especially with respect to its value for coworkers. Implications for Rehabilitation Rehabilitation efforts should continue to focus attention on the value of disability management (DM). In particular, DM that is fully committed to the biopsychosocial model would be supported by this research. Employees reported the most value in the psychosocial variables addressed by DM, such that rehabilitation professionals could focus on these valued aspects to improve buy-in from employees. The interest in coworker value may provide another avenue for rehabilitation efforts to increase uptake, by highlighting the value of intervention efforts for employee coworkers. Rehabilitation professionals in union environments may need to be particularly cognizant of the need for encouraging psychosocial and coworker value potentially seen by employees in order to increase acceptance and participation for organizational DM efforts.

Disability management and organizational culture in Australia and Canada.

BACKGROUND: Organizational culture has received increasing attention in terms of its influence on workplace health and productivity, yet there has been little research on its relationship with employer-based disability programs. OBJECTIVE: This study explored the relationship between disability management and organizational culture in Australian and Canadian organizations. METHODS: Thematic analysis was conducted on data from semi-structured interviews with 16 employees, including injured workers, human resource managers and disability managers in two Australian and two Canadian large organizations. RESULTS: Seven themes were identified: 1. Consistency between espoused beliefs and artifacts in organization; 2. Genuineness of interest in well-being of injured worker; 3. Level of ongoing support of worker following injury; 4. Communication with injured workers; 5. Level of support from supervisors and co-workers; 6. Promptness in claims processing and covering medical costs and; 7. Focus on wellness and injury prevention. It was found that organizational culture may impact the delivery and perceived value of employer-based disability management programs. CONCLUSIONS: Given the potential relationship between organizational culture and disability management, employers should facilitate a positive workplace culture by ensuring consistency among underlying values, espoused values and actual treatment of employees, including injured workers.

Can Paramedics Safely Refuse Transport of Non-Urgent Patients?

OBJECTIVE: The goal of this search was to review the current literature regarding paramedic triage of primary care patients and the safety of paramedic-initiated non-transport of non-urgent patients. METHODS: A narrative literature review was conducted using the Medline (Medline Industries, Inc.; Mundelein, Illinois USA) database and a manual search of Google Scholar (Google; Mountain View, California USA). RESULTS: Only 11 studies were found investigating paramedic triage and safety of non-transport of non-urgent patients. It was found that triage agreement between paramedic and emergency department staff generally is poor and that paramedics are limited in their abilities to predict the ultimate admission location of their patients. However, these triage decisions and admission predictions are much more accurate when the patient's condition is the result of trauma and when the patient requires critical care services. Furthermore, the literature provides very limited support for the safety of paramedic triage in the refusal of non-urgent patient transport, especially without physician oversight. Though many non-transported patients are satisfied with the quality of non-urgent treatment that they receive from paramedics, the rates of under-triage and subsequent hospitalization reported in the literature are too high to suggest that this practice can be adopted widely. CONCLUSION: There is insufficient evidence to suggest that non-urgent patients can safely be refused transport based on paramedic triage alone. Further attempts to implement paramedic-initiated non-transport of non-urgent patients should be approached with careful triage protocol development, paramedic training, and pilot studies. Future primary research and systematic reviews also are required to build on the currently limited literature. Fraess-Phillips AJ . Can paramedics safely refuse transport of non-urgent patients?
