Assessing the role of sustainability competencies in enhancing psychological first aid effectiveness for disaster responders in Fiji.

Background: Psychological first aid (PFA) is essential for mental health and wellbeing after traumatic events. Integrating competency-based outcomes is crucial with the increasing demand for effective psychological first-aid interventions. This study examines the correlation between sustainability competencies and PFA principles within Fiji's disaster responder's context. Method: The research was guided by a theoretical framework based on a comprehensive review of sustainability competencies and PFA principles. A cross-sectional survey assessed the importance of sustainability competencies in disaster responders to deliver PFA effectively. The survey used a stratified random sampling method to get diverse PFA-trained participants (66%) and non-PFA trained (34%), aiming to understand how these competencies can impact PFA success in various disaster situations. The survey, encompassing various domains of disaster response and a diverse range of respondents age, gender, and years of experience, employed the Likert scale to assess the importance of competencies such as integrated problem-solving, strategic, systems thinking, self-awareness, normative, collaboration, anticipatory, and critical thinking. Results: The study involved 49 PFA-trained participants (55% female, 45% male) and 15 non-PFA-trained participants (53% female, 46% male), excluding 10 responses from the latter group due to ambiguous answers to critical questions. The correlation between age, experience, and the valuation of professional competencies among disaster responders indicates that disaster responders, with extensive experience and PFA training, rated competencies as "important," reflecting a perspective shaped by long-term career development and practical experiences. Equally, younger and early career responders emphasize competencies as "very important," indicating an initial recognition of their significance. The appraisal patterns across different age groups, especially among those with PFA training, suggest a tendency to moderate assessments of competency importance with increasing experience. Statistical analysis, including mean, median, standard deviation, and variance, provided a detailed understanding of the data, underscoring competencies like self-awareness in both data sets and integrated problem-solving and collaboration within PFA-trained responders as the key for effective PFA interventions. Conclusion: The study underlines the critical need to integrate sustainability competencies into the PFA curriculum in Fiji's unique sociocultural context. This interplay between age, experience, and competency assessment stresses the diverse factors influencing perceptions in the disaster response field beyond experience alone. The results show that sustainability competencies are the ultimate to the effectiveness of PFA measurement and interventions. The research lays the foundation for future studies to develop validated tools for assessing sustainable competencies in different cultural contexts, thereby improving the effectiveness of PFA in disaster management. Integrating these competencies into PFA training could significantly strengthen PFA intervention and competency-based evaluation.

A longitudinal follow-up study of rescue and recovery narratives of Oklahoma City bombing responders nearly a quarter century later.

BACKGROUND: Most research examining first responders of terrorist incidents has been conducted in early post-disaster periods, utilized quantitative research methods, and focused on psychopathology such as post-traumatic stress. METHODS: Longitudinal follow-up assessments of 124 workers from 181 baseline volunteer rescue and recovery workers originally studied were completed nearly a quarter century after the terrorist bombing of the Murrah Federal Building in Oklahoma City. Open-ended qualitative interviews were used in the follow-up study. RESULTS: The rescue and recovery work, vividly described decades later, was gruesome. These workers' descriptions captured their mental toughness and their professional missions, as well as the emotional and mental health (MH) toll on their lives. CONCLUSIONS: The extreme nature of rescue and recovery work in the aftermath of terrorism suggests potential utility for MH interventions to address the psychological toll that can be expected of human beings under the most extraordinary circumstances.

Exploring medical first responders' perceptions of mass casualty incident scenario training: a qualitative study on learning conditions and recommendations for improvement.

OBJECTIVE: Despite participating in scenario training, many medical first responders (MFRs) perceive themselves as inadequately prepared to respond to mass casualty incidents (MCIs). The objective of this study was to conduct a comprehensive examination of traditional MCI scenario training methods, focusing on their inherent strengths and limitations. An investigation into the perceptions of MFRs who had participated in MCI scenario training was carried out to identify potential areas for improvement and provide recommendations for refining MCI training protocols. DESIGN: Qualitative inductive approach using semistructured interviews that took place between October 2021 and February 2022. Data were analysed with qualitative content analysis. SETTING: MCI scenario training involving four organisations (three emergency medical services and one search-and-rescue organisation) tasked with responding to MCIs, collectively representing four European Union countries. PARTICIPANTS: 27 MFRs (17 emergency medical services personnel and 10 search-and-rescue volunteers) were recruited to participate in the study. RESULTS: Two categories and seven associated subcategories (shown in parentheses) were identified as influencing the learning outcomes for MFRs: Training in a context mirroring real-world incidents (conducting incident scene risk assessment, realistic representation in casualties, incorporating scenario variety into the curriculum, interagency collaboration, role alignment when training incident site management) and use of a pedagogical framework (allowing for mistakes, the importance of post-training evaluation). CONCLUSIONS: This study reaffirms the value of traditional MCI scenario training and identifies areas for enhancement, advocating for realistic scenarios, interagency collaboration, improved incident site management skills and thorough post-training evaluation. It suggests a shift in MCI training conceptualisation and delivery. The potential of virtual reality technologies as a valuable addition to training methods is explored, with a note on the need for further research to ascertain the long-term effectiveness of these technologies. However, the selection of a training method should consider programme goals, target population and resources.

Physical and psychological status of emergency assistance personnel at major public health events: a qualitative descriptive study.

BACKGROUND: Many personnel respond to natural disasters like earthquakes and tsunamis and frequent public health events like Ebola and COVID-19. However, research on emergency assistance personnel remains limited. This study aims to describe the perceived well-being among responders deployed in isolated or emergency international missions while providing practical references to intervene in developing similar missions. METHODS: For this qualitative phenomenological study, purposive sampling was used following the principle of maximum differentiation to select personnel deployed on an emergency mission for over a year. Data collection continued until data saturation. Phenomenologically semi-structured interviews helped explore the physical and psychological status of the participants with Colaizzi's method. RESULTS: Eleven personnel were interviewed after the mission, with four major themes being identified: 'perceived somatic change,' 'perceived emotional change,' 'behavioral change,' and 'coping with perceived change.' CONCLUSIONS: The mental health status of the emergency assistance personnel was affected by multiple factors from external and internal environments. The current study explored the physical and psychological feelings and emotions of emergency assistance personnel during an emergency mission. The study provided a practical reference for health management under similar missions. REGISTRATIONS: Not registered.

Harm Reduction in the Field: First Responders' Perceptions of Opioid Overdose Interventions.

Introduction: Recent policy changes in Washington State presented a unique opportunity to pair evidence-based interventions with first responder services to combat increasing opioid overdoses. However, little is known about how these interventions should be implemented. In partnership with the Research with Expert Advisors on Drug Use team, a group of academically trained and community-trained researchers with lived and living experience of substance use, we examined facilitators and barriers to adopting leave-behind naloxone, field-based buprenorphine initiation, and HIV and hepatitis C virus (HCV) testing for first responder programs. Methods: Our team completed semi-structured, qualitative interviews with 32 first responders, mobile integrated health staff, and emergency medical services (EMS) leaders in King County, Washington, from February-May 2022. Semi-structured interviews were recorded, transcribed, and coded using an integrated deductive and inductive thematic analysis approach grounded in community-engaged research principles. We collected data until saturation was achieved. Data collection and analysis were informed by the Consolidated Framework for Implementation Research. Two investigators coded independently until 100% consensus was reached. Results: Our thematic analysis revealed several perceived facilitators (ie, tension for change, relative advantage, and compatibility) and barriers (ie, limited adaptability, lack of evidence strength and quality, and prohibitive cost) to the adoption of these evidence-based clinical interventions for first responder systems. There was widespread support for the distribution of leave-behind naloxone, although funding was identified as a barrier. Many believed field-based initiation of buprenorphine treatment could provide a more effective response to overdose management, but there were significant concerns that this intervention could run counter to the rapid care model. Lastly, participants worried that HIV and HCV testing was inappropriate for first responders to conduct but recommended that this service be provided by mobile integrated health staff. Conclusion: These results have informed local EMS strategic planning, which will inform roll out of process improvements in King County, Washington. Future work should evaluate the impact of these interventions on the health of overdose survivors.

Design considerations for protective boots for first responders to hazardous materials incidents.

First responder professionals are at high risk for work-related injuries (e.g., extreme temperatures, chemical and biological threats); boots are essential to ensure body protection since they have full contact with the ground in all scenarios. A substantial body of work has investigated the necessity of improvements in protective boots, but there is limited research conducted on boots with fit-adjustable fasteners for secure and adjustable fit within this context. Thus, this study explored the areas for improvement in boot design for the development of form-fitting and yet comfortable boots focusing on two different boot designs, prototype all-hazards tactical boots (lace-up) and rubber boots (slip-on). Findings indicated that the boot design should address participants' concerns with the material choices of boots, specifically with bulkiness, weight, and flexibility. Our findings provide insights into boot material and design choices to improve protective boots for first responders.

HAZMAT Technician-level Emergency Response: A Mental Model Framework for Radiological Dispersal Device (RDD) Incidents.

ABSTRACT: This research examines the cognitive frameworks used by HAZMAT technicians when responding to incidents involving Radiological Dispersal Devices (RDDs), which are conventional explosive devices with radioactive materials incorporated. The objective is to introduce the Expected Mental Model State (EMMS) as a comprehensive evaluation tool for assessing and enhancing the expertise and situational awareness of emergency responders dealing with radiation crises. Through a series of expert focus group sessions using the well-established qualitative methodology of grounded theory, an Expected Mental Model State (EMMS) was developed. The methodology used an influence diagram architecture to conceptually capture and codify key areas relevant to effective emergency response. The research identifies fourteen EMMS key conceptual domains, further elaborated into 301 subtopics, providing a multi-dimensional structure for the proposed mental model framework. Three pivotal notions of mental model emerged within the EMMS framework: Knowledge Topology, Envisioning (Belief), and Response and Operability. These notions were found to align with previous theories of mental models and are vital for understanding how HAZMAT technicians conceptualize and respond to RDD incidents. The study emphasizes the critical role of mental models in enhancing preparedness and effective response strategies during radiation emergencies. The EMMS framework offers a versatile methodology that can be adapted across various kinds of emergency responders and high-risk situations, including the broader Chemical, Biological, Radiological, and Nuclear (CBRN) spectrum. Using this EMMS framework to develop an EMMS Diagnostic Matrix can provide a roadmap for identifying areas for the development of specialized training modules that have the potential to significantly elevate both the quality and efficacy of responder training and preparation.

Lack of association of impaired upper airway sensation with the presence or absence of obstructive sleep apnoea or chronic rhinosinusitis in World Trade Center responders.

OBJECTIVE: Examine sensory function of the upper airway in four groups of subjects recruited from the World Trade Centre General Responder Cohort (WTCGRC), with/without obstructive sleep apnoea (OSA), and with/without chronic rhinosinusitis (CRS). METHODS: Upper airway sensory function was determined using 2-point discrimination (2-PD) and vibration threshold (VT) in 163 WTCGRC subjects with both OSA and CRS (cases), OSA or CRS alone and without OSA or CRS (controls). Presence of OSA was determined from clinical sleep studies or home sleep testing. Presence of CRS was determined by nasal symptom questionnaire. The relationship between the presence of OSA and CRS and upper airway sensory impairment was assessed using linear regression analysis with each of 2PD and VT sensory threshold values as the dependent variable; OSA, CRS and their interaction were the independent variables. Age, gender and body mass index were covariates in the statistical model. The primary analysis was comparison of OSA+CRS versus controls (no OSA and no CRS) evaluated by linear contrasts. RESULTS: There were no differences in 2-PD or VT in those with OSA+CRS, OSA and CRS alone or controls. However, both 2-PD and VT were significantly higher in the WTCGRC controls compared with values seen in historical controls using the same methodology (median 2-PD 13.0; CI (11.0 to 13.5) vs 10.5; CI (8 to 11); VT: mean±SEM (9.3±0.6 vs 2.2±0.1)). CONCLUSION: While no differences were found in upper airway sensation between cases of OSA and CRS versus controls in the WTGRC population, there was evidence of impaired upper airway sensation in the WTGRC overall.

Formulating policies and procedures for managing diving related deaths: a whole of state engagement from frontline and hospital services in Tasmania.

Introduction: Tasmania is a small island state off the southern edge of Australia where a comparatively high proportion of the 558,000 population partake in recreational or occupational diving. While diving is a relatively safe sport and occupation, Tasmania has a significantly higher diving death rate per head of population than other States in Australia (four times the national diving mortality rate). Methods: Three compressed gas diving deaths occurred in seven months between 2021-2022 prompting a review of the statewide approach for the immediate response of personnel to diving-related deaths. The review engaged first responders including the Police Marine and Rescue Service, hospital-based departments including the Department of Hyperbaric and Diving Medicine, and the mortuary and coroner's office. Results: An aide-mémoire for all craft groups, digitalised checklists for first responders (irrespective of diving knowledge), and a single-paged algorithm to highlight inter-agency communication pathways in the event of a diving death were designed to enhance current practices and collaboration. Conclusions: If used, these aids for managing diving related deaths should ensure that time-critical information is appropriately captured and stored to optimise information provided for the coronial investigation.

'Safety in the Grey Zone': Evaluation of a training program to improve the safety of incident responders on high-speed roads.

INTRODUCTION: Workers operating on high-speed roads (i.e., incident responders and emergency service workers) are at significant risk of being fatally injured while working. An identified gap in current prevention strategies is training focused on developing the skills of workers to effectively communicate and coordinate safety responses when operating on roads. METHODS: This study discusses the development of a program designed to optimize communication and coordination of safety practices at the scene of an incident on a high-speed road. The program is referred to as 'Safety in the Grey Zone.' The goal of the study is to present the results from an evaluation on its implementation across 23 sessions involving 158 participants from 7 incident response agencies in 1 state in Australia. RESULTS: The results of this study provide support for effectiveness in implementing the program as planned. The results also provide preliminary support for effectiveness of the program in achieving its learning outcomes as demonstrated by feedback received from participants following completion of the program. CONCLUSIONS: The findings of this study provide recommendations to consider in the program's future roll-out, as well as suggestions for future evaluations to assess the program's effectiveness in improving the safety of incident responders operating on high-speed roads.

Incidence of Dementia Before Age 65 Years Among World Trade Center Attack Responders.

Importance: Reports suggest that the individuals who served in rescue operations following the terrorist attacks on the World Trade Center (WTC) have poorer brain health than expected. Objective: To assess the incidence of dementia before age 65 years in a prospective study of WTC responders and to compare incidence among responders with severe exposures to debris vs responders not exposed to building debris or who wore personalized protective equipment (PPE). Design, Setting, and Participants: This prospective cohort study was conducted from November 1, 2014, to January 1, 2023, in an academic medical monitoring program available to verified WTC responders residing on Long Island, New York. Responders 60 years of age or younger without dementia at the time of their first cognitive assessment were followed up every 18 months, on average, for up to 5 years. Exposures: Exposure severity was based on responses to a detailed questionnaire of WTC exposures and exposure-related activities that included exposures to fine particulate dust and potentially neurotoxic debris, duration of work, and the use of PPE. Exposure level was divided into 5 categories ranging from low to severe. Main Outcomes and Measures: Incidence of all-cause dementia before age 65 years was the primary outcome. Dementia was diagnosed following standard guidelines relying on repeated measures of cognition. Results: Of 9891 responders, 5010 were eligible for inclusion in this study of cognitive function (median [IQR] age, 53 [48-57] years; 4573 [91.3%] male). There were 228 cases of dementia identified during 15 913.1 person-years of follow-up. Increasing WTC exposure severity was associated with incremental increases in the incidence rate of dementia per 1000 person-years (low, 2.95 [95% CI, 1.07-11.18]; mild, 12.16 [95% CI, 10.09-14.79]; moderate, 16.53 [95% CI, 13.30-20.81]; high, 30.09 [95% CI, 21.35-43.79]; and severe, 42.37 [95% CI, 24.86-78.24]). Adjusting for social, demographic, and relevant medical factors, each unit increase in exposure severity was associated with increased incidence of dementia (adjusted hazard ratio, 1.42 [95% CI, 1.18-1.71]; P < .001; mean risk difference, 9.74 [95% CI, 2.94-32.32] per 1000 person-years; P < .001). Conclusions and Relevance: In this cohort study of WTC responders who survived these unique exposures and participated in a longitudinal follow-up study of cognition from 2014 through 2022, when compared with responders with the lowest exposure levels or responders who used PPE, more severe exposure to dust or debris was significantly associated with a higher risk of dementia before 65 years of age. This study suggests that the reliable use of PPE might help prevent the onset of dementia before age 65 years among individuals exposed to an uncontrolled building collapse. Future research is warranted to determine cerebral biomarkers for individuals with exposure-associated dementia.

Évaluation du risque par les professionnels de la santé et les équipes de secours lors d'incidents chimiques.

CONTEXT: The literature review highlights that joint preparation and training of first aid responders is necessary to deal with a major chemical incident. Improved knowledge of exposure assessments makes it possible to estimate the risk and adjust immediate measures. The aim of this paper is to summarize recommendations for assessing exposure during chemical incidents that require emergency responses. Actions allowing the chemical contamination to be better anticipated and health protection to be optimized were analyzed. METHODOLOGY: A review of the literature was conducted, and research questions were formulated using the PECO method. The PRISMA method was used to select the literature. RESULTS AND DISCUSSION: The selected papers (n=16) show that preparation for chemical incidents in terms of individual and collective protective equipment, and knowledge of the risk assessment process remain lacking. We propose training to master the steps of risk assessment. Our analysis also points out the importance of monitoring the state of the environment after a chemical incident, allowing adjusted measures to protect the health of the exposed population and vulnerable groups in particular. This monitoring must be accurate and dynamic to provide realistic recommendations during the intervention phase. CONCLUSIONS: All first-aid responders and health workers knowing the risk assessment process should result in improvements: in the use of protective measures in time and space, the delimitation of exposure to contamination, and the characterization of the risk.

Use of Self-Efficacy Scale in Mass Casualty Incidents During Drill Exercises.

INTRODUCTION: Medical First Responders (MFRs) in the emergency department SUMMA 112 are tasked with handling the initial management of Mass Casualty Incidents (MCI) and building response capabilities. Training plays a crucial role in preparing these responders for effective disaster management. Yet, evaluating the impact of such training poses challenges since true competency can only be proven amid a major event. As a substitute gauge for training effectiveness, self-efficacy has been suggested. OBJECTIVE: The purpose of this study is to employ a pre- and post-test assessment of changes in perceived self-efficacy among MFRs following an intervention focused on the initial management of MCI. It also aimed to evaluate a self-efficacy instrument for its validity and reliability in this type of training. METHOD: In this study, we used a pretest (time 1 = T1) - post-test (time 2 = T2) design to evaluate how self-efficacy changed after a training intervention with 201 MFRs in initial MCI management. ANOVA within-subjects and between subjects analyses were used. RESULTS: The findings reveal a noteworthy change in self-efficacy before and after training among the 201 participants. This suggests that the training intervention positively affected participants' perceived capabilities to handle complex situations like MCI. CONCLUSION: The results allow us to recommend a training program with theory components together with practical workshops and live, large-scale simulation exercises for the training of medical first responders in MCI, as it significantly increases their perception of the level of self-efficacy for developing competencies associated with disaster response.

Exposure to aggression in three contexts of emergency response: A longitudinal examination of the relationship with psychological characteristics of the emergency responder.

Some emergency responders are more often exposed to workplace aggression than others. Victimological theories and previous studies suggest that characteristics of the target may predict exposure to workplace aggression. This paper examines the relationship between negative affect, hostile attribution, dominance, empathy, self-evaluations, and exposure to workplace aggression among emergency responders. Emergency medical workers, firefighters and police officers in the Netherlands filled in a survey during three measurement occasions (6 months apart). Results from the three occupational groups were presented separately. Results suggest that some psychological characteristics are related to exposure to workplace aggression, but that the contribution of these characteristics in the explanation of exposure to workplace aggression is limited. In addition, although differences between occupational groups could not be statistically tested due to differences in the factor structure of exposure to workplace aggression between the three groups of emergency response, differences seem to occur in models between emergency response contexts. Implications and suggestions for future research are discussed.

Tourniquet application in time-critical aquatic emergencies on a moving rescue water craft (RWC): Can speed and precision coexist?

Lifeguards are the first responders to any type of aquatic incident, including rapid rescue situations such as boating and sporting accidents, animal bites/attacks, and cases involving massive bleeding. In their line of work, rescue boats such as Rescue Water Craft (RWC) are commonly utilized the aim of this study is to evaluate the time and technique of placing a tourniquet on the sled of an RWC navigating at full speed. METHODS: A randomized crossover study design was used with a sample of 44 lifeguards. The inclusion criteria required that participants be certified lifeguards with experience in RWC operations and possess knowledge of responding to massive bleeding. Two CAT tourniquet placement tests were performed. In the 1) Beach-Tourniquet (B-TQ) test: it was performed on land and in the 2) Rescue Water Craft-tourniquet (RWC-TQ) test, sailing at a cruising speed of 20 knots. The evaluation was recorded in a checklist on the steps and timing of the correct application TQ by direct observation by an expert instructor. RESULTS: The tourniquet placement on RWC was an average of 11 s slower than when placed on the beach (BT-TQ 35.7 ± 8.0 vs. 46.1 ± 10.9 s, p > 0.001). In the percentage analysis of the results on correct execution of the skills, higher values are obtained for the B-TQ test than in RWC-TQ in Distance to the wound (into 5-7 cm), band adjustment, checking the radial pulse and reporting the time of tourniquet placement (p > 0.005). CONCLUSION: The placement of a tourniquet on a RWC navigating at 20 knots is feasible, relatively quick, and technically well executed.

Protective factors of psychological vulnerability in Rescue 1122 workers with vicarious traumatization.

OBJECTIVES: This study aimed to determine the protective factors of psychological vulnerability in Rescue 1122 workers and to find out the difference in work mattering, coping, grittiness, and psychological vulnerability between rescue workers of fire service and ambulance service department with vicarious traumatization. METHOD: A cross-sectional design was used in this study. A sample of 112 male rescue workers was collected from Rescue 1122 department, including participants from the ambulance service (n = 56) and fire service (n = 56) departments through a purposive sampling technique. Rescue workers who experienced vicarious trauma were enrolled in this study after screening through the secondary traumatic stress tool. Work mattering scale, coping strategies questionnaire, short grit scale, and the four-dimensional symptom questionnaire were used. RESULTS: Age, marital status, spouse age, and father's age were significantly positively correlated with distress. Colleagues becoming a target of violence and death of a colleague during duty were significantly positively correlated with somatization. The number of children was a significant positive predictor, and members requiring financial support were a significant negative predictor of psychological vulnerability. Interpersonal mattering, active focused, and active distracting coping emerged as significant negative predictors of distress, anxiety, and depression after controlling for covariates. A significant difference was found in active distraction coping between the fire service and ambulance service departments. CONCLUSION: Rescue workers who considered that their work mattered used religious coping and distraction or adopted a practical approach toward dealing with stress, and those who were grittier were less vulnerable to psychological symptoms. So, these can be considered as protective factors of psychological vulnerability.

A pilot study to identify factors associated with frailty within the World Trade Center general responder cohort.

BACKGROUND: Given the significant exposures experienced by the World Trade Center (WTC) general responders, there is increasing interest in understanding the effect of these exposures on aging in this population. We aim to identify factors that may be associated with frailty, a clinical syndrome characterized by a decrease in one's reserve that has been linked to poor health outcomes. METHODS: WTC general responders enrolled in the WTC Health Program aged 50 and older provided informed consent. Validated frailty assessments, the Frailty Phenotype (with the Johns Hopkins Frailty Assessment Calculator) along with the FRAIL scale, categorized nonfrail from prefrail/frail. Fall risk, functional status, and cognition were also assessed. WTC variables, including an identified WTC-certified condition, were utilized. The risk of frailty was estimated using log binomial regression analysis. A 95% confidence interval (CI) was used to estimate the prevalence ratio (PR). RESULTS: One hundred and six participants were included; 38 (35.8%) were classified as pre-frail or frail. More of the pre-frail/frail group were obese (57.9% vs. 25%; p = 0.004) and had a WTC-certified condition (78.9% vs. 58.8%; p = 0.036). Obesity (PR = 2.43, 95% CI = 1.31, 4.53), a WTC-certified condition (PR = 1.77, 95% CI = 1.09, 2.89), and risk of falling (PR = 1.97, 95% CI = 1.01, 3.84) were independently associated with frailty. CONCLUSIONS: Obesity and having a WTC-certified condition were found to be risk factors for frailty in our pilot study. Future work may focus on further identifying risk factors for frailty in the larger WTC general responder population.

Evaluation of system based psychological first aid training on the mental health proficiency of emergency medical first responders to natural disasters in China: a cluster randomised controlled trial.

OBJECTIVE: To evaluate the effectiveness of a system based psychological first aid (PFA) training programme for emergency medical first responders in China. DESIGN: Parallel-group, assessor-blinded, cluster randomised controlled trial. SETTING: 42 clusters of health workers from various health facilities in China. PARTICIPANTS: 1399 health workers who provide emergency service for survivors of disasters. INTERVENTIONS: One-day system based PFA training programme (PFA) or training as usual (TAU). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the PFA skills, knowledge and attitude (SKA-PFA) score at 2 months postintervention. Secondary outcomes included post-traumatic growth, self-efficacy and professional quality of life. RESULTS: The intervention group (n=690) had significantly higher SKA-PFA scores than the control group (n=709) at 2 months postintervention (adjusted mean difference=4.44; 95% CI 1.17 to 7.52; p=0.007; Cohen's d=0.35). The intervention group also had higher scores on post-traumatic growth (p=0.113, d=0.24), self-efficacy (p=0.032, d=0.20) and professional quality of life (p=0.281, d=0.04). CONCLUSIONS: The system based PFA training programme was more effective than the TAU in enhancing the PFA knowledge and skills of the emergency medical first responders and in increasing their competence to provide emergency service for survivors in China. TRIAL REGISTRATION NUMBER: ChiCTR2200060464.

"This is it this is our normal" - the voices of family members and first responders experiencing duty-related trauma in Ireland.

BACKGROUND: Compared to other occupational groups, first responders (FR) experience worse mental health outcomes due to duty-related trauma and occupational stressors. Despite their best efforts, they bring this stress home to friends and family. Consequently, FR and their supporters suffer from increased psychosocial difficulties and experience stigma and other barriers to help-seeking. Prior work offers little opportunity for open dialogue and shared understanding of the repercussions of this occupation for all members of the first responder community. In this qualitative study, we aimed to: (i) explore the lived experience of Irish FR and their family members (FM) related to occupational stressors, and (ii) identify opportunities to engage FM with existing organizational supports available for FR. METHODS: Using a community based participatory research (CBPR) approach, we conducted six focus groups involving a total of fourteen participants comprising FR, organizational representatives, and FM. All focus groups were audio recorded, transcribed, and analyzed using reflexive thematic analysis. FINDINGS: FR and FM shared their experiences of both joining and learning to live as members of the FR community in Ireland. Through our analysis, we identified a main theme of 'crossing thresholds', characterizing their transformative learning experiences. This learning experience includes recognizing the consequences of this new role for them as individuals and for their relationships. Participants also shared how they have learned to cope with the consequences of their roles and what they need to better support each other. CONCLUSIONS: FM are often unheard, hidden members of the first responder community in Ireland, highlighting an unmet need for FR organizations to acknowledge FM role in supporting FR and to provide them with the appropriate training and resources required. Training for new recruits needs to move beyond the tokenistic involvement of FM and encourage knowledge sharing among experienced and novice members. Cultural change is required to support help-seeking among FR and foster a sense of peer support and community among families.
