Post-traumatic stress disorder and its predictors in emergency medical service personnel: a cross-sectional study from Karachi, Pakistan (original) (raw)

The impact of traumatic stressors in civilian occupational settings

Journal of Public Health Policy, 2009

We use the literature reporting prevalence and aetiology of posttraumatic stress disorder (PTSD) in first responders as a catalyst to discuss for organisations the policy implications for prevention and intervention of psychiatric morbidity. We searched PubMed and Google to identify studies and reports of mental health and behavioural problems in occupations including police, fire, and emergency service workers. The prevalence of PTSD ranged from 6 per cent to 32 per cent. Biological markers of PTSD, such as neuroendocrine activity, appear less useful than psychological markers, such as levels of hostility and self-efficacy, to predict PTSD. Prevalence of PTSD was generally less than that found among victims themselves, but higher than general community prevalence. Theoretically, if prevention and intervention strategies were working effectively, there should be a minimal rate of psychiatric morbidity attributable to these individuals' workplaces. Against this background, there is a case for routine screening on an annual basis for those at risk.

Predictors of Emotional Distress in Combat Military Flight Engineers

Military Medicine, 2021

Exposure to distressing sights (DSs) during combat missions may cause emotional distress. The present study aimed to investigate the association between exposure to DSs involving severe injuries and fatalities during rescue missions and emotional distress, in Israeli Air Force (IAF) helicopter flight engineers (FEs). Methods: Cross-sectional design using self-report questionnaires. The independent variables included demographics, personal, and military variables-exposure to DSs throughout a whole career service. The dependent variables included Depression (Beck Depression Inventory); State-Trait Anxiety Inventory; Post-traumatic stress disorder (PTSD Checklist-PCL-5); Somatization (Patient Health Questionnaire); Maslach Burnout Inventory; and Coping Strategies (The Brief COPE). The variables PTSD, depression, and anxiety were examined twice: once as dichotomous variables according to the pathology cutoff point and again as a continuous variable to reveal the intensity of symptoms. Results: Participants were 106 IAF helicopter FEs (mean age = 39.32, SD = 8.75). Linear regression revealed that initial exposure to distressing battlefield sights (i.e., exposure to severe injuries and fatalities) was a predictor of depression symptoms. Career service FEs aged 31-40 were found to be at the highest risk of emotional distress, with a predictive factor for anxiety symptoms. Use of nonadaptive coping strategies was found to predict depressive symptoms, anxiety symptoms, and post-traumatic stress symptoms. Conclusion: A significant association was found between exposure to DSs involving severe injuries and fatalities during rescue missions and anxiety, depression, somatization, and burnout. This population is generally perceived as tough and resilient, and this study has a unique contribution in identifying its vulnerabilities. Psychological intervention is crucial after participating in such missions.

Work-related psychosocial hazards among emergency medical responders (EMRS) in Mansoura city

Indian Journal of Community Medicine, 2014

Purpose: This research was done to assess levels of psychosocial stress and related hazards [(burnout, depression, and posttraumatic stress disorder (PTSD)] among emergency medical responders (EMRs). Materials and Methods: A comparative cross-sectional study was conducted upon (140) EMRs and a comparative group composed of (140) nonemergency workers. The groups studied were subjected to semistructured questionnaire including demographic data, survey for job stressors, Maslach burn out inventory (MBI), Beck depression inventory (BDI), and Davidson Trauma scale for PTSD. Results: The most severe acute stressors among EMRs were dealing with traumatic events (88.57%), followed by dealing with serious accidents (87.8%) and young victims (87.14%). Chronic stressors were more commonly reported among EMRs with statistically significant differences (P < 0.05) except for social support with colleagues and supervisors. EMRs had statistically significant higher levels of emotional exhaustion (EE) (20%) and depersonalization (DP) (9.3%) compared with comparative group (4.3%, 1.4% respectively). Also, there was no statistically significant difference between two groups as regards lower personal achievement or depression symptoms (P > 0.05). There was increased risk of PTSD for those who had higher stress levels from death of colleagues [odds ratio (OR) [95% confidence interval (CI)] = 2.2 (0.7-7.6), exposure to verbal or physical assault OR (95% CI) = 1.6 (0.5-4.4) and dealing with psychiatric OR (95% CI) 1.4 (0.53.7) (P > 0.05) Conclusion: EMRs group had more frequent exposure to both acute and chronic work-related stressors than comparative group. Also, EMRs had higher levels of EE, DP, and PTSD compared with comparative group. EMRs are in need for stress management program for prevention these of stress related hazards on health and work performance.

Trauma exposure, posttraumatic stress disorder and the effect of explanatory variables in paramedic trainees

BMC Emergency Medicine, 2014

Background Emergency healthcare workers, including trainees and individuals in related occupations are at heightened risk of developing posttraumatic stress disorder (PTSD) and depression owing to work-related stressors. We aimed to investigate the type, frequency, and severity of direct trauma exposure, posttraumatic stress symptoms and other psychopathology amongst paramedic trainees. In order to create a risk profile for individuals who are at higher occupational risk of developing PTSD, we examined risk and resilience factors that possibly contributed to the presence and severity of posttraumatic symptomatology. Methods Paramedic trainees (n = 131) were recruited from a local university. A logistic regression analysis was conducted using the explanatory variables age, gender, population group, trauma exposure, depression, alcohol abuse, alcohol dependence, resilience and social support. Results 94% of paramedic trainees had directly experienced trauma, with 16% meeting PTSD crit...

Building Psychological Resiliency and Mitigating the Risks of Combat and Deployment Stressors Faced by Soldiers

Combat is arguably the most mentally, physically and emotionally demanding enterprise that a Soldier engages in. Combat is sudden, intense, and life-threatening. A Soldier in combat encounters numerous traumatic events to include, among others, killing an enemy combatant, knowing someone seriously injured or killed or handling or uncovering human remains. All of these events can have deleterious effects on the mental health and emotional well-being of the Soldier. Yet, there are things that Soldiers, leaders and the Army can do to mediate or attenuate the impact that the stressors of combat and deployment produce. In this presentation we will provide an overview of our three intervention strategies involving

Chronic occupational exposures can influence the rate of PTSD and depressive disorders in first responders and military personnel

Background: First responders and military personnel experience rates of post-traumatic stress disorder (PTSD) far in excess of the general population. Although exposure to acute traumatic events plays a role in the genesis of these disorders, in this review, we present an argument that the occupational and environmental conditions where these workers operate are also likely contributors. Presentation of the hypothesis: First responders and military personnel face occupational exposures that have been associated with altered immune and inflammatory activity. In turn, these physiological responses are linked to altered moods and feelings of well-being which may provide priming conditions that compromise individual resilience , and increase the risk of PTSD and depression when subsequently exposed to acute traumatic events. These exposures include heat, smoke, and sleep restriction, and physical injury often alongside heavy physical exertion. Provided the stimulus is sufficient, these exposures have been linked to inflammatory activity and modification of the hypothalamic–pituitary axis (HPA), offering a mechanism for the high rates of PTSD and depressive disorders in these occupations. Testing the hypothesis: To test this hypothesis in the future, a case–control approach is suggested that compares individuals with PTSD or depressive disorders with healthy colleagues in a retrospective framework. This approach should characterise the relationships between altered immune and inflammatory activity and health outcomes. Wear-able technology, surveys, and formal experimentation in the field will add useful data to these investigations. Implications of the hypothesis: Inflammatory changes, linked with occupational exposures in first responders and military personnel, would highlight the need for a risk management approach to work places. Risk management strategies could focus on reducing exposure, ensuring recovery, and increasing resilience to these risk contributors to minimise the rates of PTSD and depressive disorders in vulnerable occupations.

Mental Wellbeing Monitoring in a Sample of Emergency Medical Service Personnel

Occupational Diseases and Environmental Medicine, 2020

Background: There have been concerns regarding the mental wellbeing of emergency medical service staff, particularly when faced with multiple trauma exposures. This study aimed to describe a cross-sectional view of the mental wellbeing status of emergency medical service workers, as well as to comment on the usefulness of an electronic survey tool to reach staff that is distributed across large geographical areas. Methods: The data presented here are drawn from an anonymous, voluntary, electronic survey, made available via the internet, to emergency medical service workers in the Western Cape province of South Africa. This paper reports on four domain expressions of mental wellbeing, namely disordered mood, problematic substance use, post-traumatic stress disorder, and domestic discord. Results: Elevated rates were reported by this sample, across all four distress domains, i.e. mood disorder = 12.3%; problematic substance use = 14.9%; post-traumatic stress disorder = 11.9%; and domestic discord = 11.9%. These rates were generally similar to data from comparable emergency worker groups, and much higher than local population estimates. Conclusions: The data support earlier findings that emergency medical work is associated with increased risk for symptoms of psychological distress, which present a strong case for regular organizational monitoring of employees' mental wellbeing. In this regard, a brief, internet delivered, survey-type tool showed promise for screening employees, in order to guide further streaming of distressed individuals towards appropriate support services. Further work is required to develop clear mechanisms for referral and intervention in order to optimize a confidential and supportive monitoring program.

Predictors of emotional distress reported by soldiers in the combat zone

Journal of Psychiatric Research, 2010

Objective: Few studies have examined rates of distress of military personnel during deployment to a war zone. Our study sought to (a) identify rates of self-reported posttraumatic stress disorder (PTSD) and depression symptoms during combat deployment, (b) characterize higher order dimensions of emotional distress experienced by soldiers during deployment, and (c) identify predictors of these dimensions of emotional distress. Method: Participants were 2677 National Guard soldiers deployed as part of Operation Iraqi Freedom in 2006-07. We performed a principal components factor analysis on items of the PTSD Checklist -Military Version and the Beck Depression Inventory to identify dimensions of emotional distress, followed by multiple regression analyses to identify factors that predicted these dimensions of distress. Results: Rates of PTSD and depression in our sample were 7% and 9%, respectively. Five dimensions of emotional distress emerged: negative affect/cognitions, trauma-specific re-experiencing and avoidance, vegetative symptoms, loss of interest/numbing symptoms, and arousal/irritability. Two dimensions, trauma-specific symptoms and arousal/irritability, appeared to be more indicative of trauma sequelae, while the other three dimensions were more indicative of depressive symptoms. Demographic factors, combat exposure (including injury and exposure to explosive blast), and attitudinal variables predicted traumaspecific aspects of distress. Symptoms characteristic of depression or generalized distress were predicted by female gender, recent prior deployment, and attitudinal factors but were not predicted by blast exposure or injury. Conclusions: These findings suggest specific targets for contextual and individual interventions to reduce deployment-related distress and point out the need for longitudinal follow-up to determine long-term implications for post-deployment functioning.

A cross-sectional study of mental health-, posttraumatic stress symptoms and post exposure changes in Norwegian ambulance personnel

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, 2022

Background: Posttraumatic stress disorder (PTSD) has been shown to be elevated among first responders (Emergency Medical Services, fire service, police force) compared to the general population. Examining the prevalence of mental health issues in a work force with an elevated occupational risk is fundamental towards ensuring their wellbeing and implementing safeguard measures. The goal of this study is therefore to report the prevalence of depression, anxiety, posttraumatic development, and PTSD in Norwegian ambulance personnel. Methods: This study is a cross-sectional, anonymous, web-based survey (Questback ®), performed among operative personnel employed in the Emergency Medical Services in the Regional Health Trust of Central Norway between 18. February and 9. April 2021. The study was sent to 1052 eligible participants. Questions reported demographic data, a traumatic events exposure index, Patient Health Questionnaire-9 (Depression), Generalized Anxiety Disorder-7 scale, Posttraumatic symptom scale (PTSD) and Posttraumatic change scale. Results: The response rate in this study was 45.5% (n = 479/1052). The mean age of respondents was 37.1 years (std. 11.1) and 52.8% (n = 253) were male. Of the respondents, 80.6% (n = 386) were married or had a partner, and 91.6% (n = 439) reported having access to a peer support programme, with 34.9% (n = 167) reporting that they had utilized peer support. In this study, 5% (n = 24) showed a prevalence of manifest posttraumatic stress disorder symptoms, while 8.6% (n = 41) reported moderate to severe depression and 2.9% (n = 14) presented moderate to severe symptoms of general anxiety. Of the respondents, 77.2% (n = 370) reported personal growth because of their work experiences. Conclusions: This study indicates that Norwegian ambulance personnel report a prevalence of posttraumatic stress symptoms and depression, which is slightly higher for men, and lower for the female proportion in this study, when compared to an adult Norwegian population. The vast majority of respondents reported personal growth because of their work experience, and both the degree of peer support and having a partner seem to influence levels of posttraumatic stress and-development.
