Physical fitness profile of a large urban fire department: Exploring age and rank dynamics.

BACKGROUND: Firefighter physical fitness (PF) plays a crucial role in mitigating health issues and supporting occupational performance. The influence of rank on firefighter PF remains understudied and previous research is often limited by small sample sizes of firefighters volunteering for research studies, potentially biasing results towards fitter firefighters not representative of entire departments. OBJECTIVE: To examine the PF profile of firefighters in a large urban fire department and the influence of age and rank on PF. METHODS: Data, including muscular fitness, estimated aerobic capacity (VO2max), and body fat percentage (BF%) measures from 1361 firefighters (90% male; age: 37.4±10.1yrs; 60 recruits, 973 firefighters, 290 lieutenants/captains, 38 chiefs) were analyzed. Correlation and ANCOVAs were conducted to examine the impact of rank on PF while controlling for age. Score distributions were scrutinized to profile the PF of the department. RESULTS: Age was negatively associated with pull-ups (r = - 0.39), sit-ups (r = - 0.39), and push-ups (r = - 0.32), but positively associated with relative VO2max (r = 0.17) and BF% (r = 0.39). Rank had a statistically significant, but trivial effect size, on pull-ups (p = 0.028, η2 = 0.007) and sit-ups (p = 0.034, η2 = 0.005). Firefighters with lower PF levels were older, had higher BF%, lower fat-free mass, and were a greater proportion of females. CONCLUSIONS: Firefighters exhibited diverse levels of PF. Age, not rank, appeared to influence firefighters' PF. The findings that firefighters who were older, female, with poorer body composition are more likely to have lower PF levels highlights the need for individualized PF training to enhance occupational performance and health across the fire department.

Emergency services response to eCall System alerts: Observations from 2016-2022 in the National Fire and Rescue System.

OBJECTIVE: Analysis of interventions by fire protection units in road traffic incidents alerted by the eCall system between 2016 and 2022. MATERIALS AND METHODS: Data from the State Fire Service Decision Support System (SFS DSS), provided by the Operational Planning Office, were used. Events from January 1, 2016, 00:00 to December 31, 2022, 23:59 were analyzed. Quantitative data were described using mean (Mean) and standard deviation (SD). Correlations and differences at a significance level of p < 0.05 were considered statistically significant. The analysis is anonymous for both victims and officers involved in the interventions. RESULTS: Between 2016 and 2022, firefighters were alerted by the e-call system 896 times. The shortest average intervention time was 47 ± 37 min and was recorded in 2021. In the comparative analysis of intervention time and factors conditioning the use of the eCall system, it was shown that this time was significantly statistically dependent on the number of cars involved in the incident (p < 0.001), the number of injured persons (p < 0.001), the type of intervention (p < 0.001),), and the occurrence of fuel leakage (p < 0.001). CONCLUSIONS: ECall is a relevant system for reporting accidents and collisions on the road. While it proves reliable in road incidents, a significantly high number of false alarms initiated from eCall requires system refinement to avoid accidental alarms and user education about the possibility of unintentionally sending an alarm signal. The authors predict that as the number of vehicles with the eCall system introduced to the roads increases, so will the number of notifications from this system. Data from the analysis of false reports suggest that mechanics and electricians in facilities performing repairs and maintenance of vehicles with the eCall system may lack the necessary knowledge of the need to deactivate the system before starting work. The number of injured people had no impact on the intervention time, which may prove that the rescue services were properly prepared.

Nocardia brasiliensis Pyomyositis in an Immunocompetent Patient Following Gardening Activity.

Nocardia pyomyositis in immunocompetent patients is a rare occurrence. The diagnosis may be missed or delayed with the risk of progressive infection and suboptimal or inappropriate treatment. We present the case of a 48-year-old immunocompetent firefighter diagnosed with pyomyositis caused by Nocardia brasiliensis acquired by direct skin inoculation from gardening activity. The patient developed a painful swelling on his right forearm that rapidly progressed proximally and deeper into the underlying muscle layer. Ultrasound imaging of his right forearm showed a 7-mm subcutaneous fluid collection with surrounding edema. Microbiologic analysis of the draining pus was confirmed to be N brasiliensis by Matrix-Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-TOF) Mass Spectrometry. After incision and drainage deep to the muscle layer to evacuate the abscess and a few ineffective antibiotic options, the patient was treated with intravenous ceftriaxone and oral linezolid for 6 weeks. He was then de-escalated to oral moxifloxacin for an additional 4 months to complete a total antibiotic treatment duration of 6 months. The wound healed satisfactorily and was completely closed by the fourth month of antibiotic therapy. Six months after discontinuation of antibiotics, the patient continued to do well with complete resolution of the infection. In this article, we discussed the risk factors for Nocardia in immunocompetent settings, the occupational risks for Nocardia in our index patient, and the challenges encountered with diagnosis and treatment. Nocardia should be included in the differential diagnosis of cutaneous infections, particularly if there is no improvement of "cellulitis" with traditional antimicrobial regimens and the infection extends into the deeper muscle tissues.

Risk Factors Associated with Suicidal Ideation and Suicidal Behavior in Wildland Firefighters.

INTRODUCTION: Wildland firefighters are posited to have a higher suicide rate than general firefighters and the general population. However, the rates and risk factors of suicide among wildland firefighters is not fully understood. METHODS: For this preregistered study, 564 participants were recruited from Facebook to obtain a final sample of 246 participants with valid data who were current or former wildland firefighters in the United States. Participants completed online measures of suicidal ideation, history of suicidal behaviors, posttraumatic stress disorder (PTSD) symptoms, problematic alcohol use, and occupational exposure to suicide. RESULTS: In this sample, 22% of wildland firefighters reported a history of at least one suicide attempt, and 36.7% reported current suicidal ideation. PTSD symptoms, but not problematic alcohol use or exposure to suicide, were positively associated with suicidal ideation and a history of suicide attempts. Additionally, PTSD symptoms explained significantly more variance in suicidal ideation than depression symptoms alone. CONCLUSIONS: Wildland firefighters demonstrate rates of suicide attempts that exceed those of non-wildland firefighters and of the general population at large. In addition, PTSD symptoms may contribute to suicidal thoughts and behaviors (STB) in this population. This is the largest study of STB in wildland firefighters to date.

Safety climate and seat belt use in the fire service.

OBJECTIVE: Motor vehicle incidents or apparatus crashes are a leading cause of firefighter fatalities in the United States. Nonuse of seat belts has been linked to some of these fatalities. This research seeks to understand the relationship between safety climate and seat belt use among firefighters, as findings will provide insights into factors that may bolster seat belt use and protect firefighters. METHODS: Data were collected from 208 career firefighters working for a city fire department in the southeastern United States. Structural equation modeling was used to test a hypothesized model and to assess the relationships between organizational safety climate, work group safety climate and seat belt use. RESULTS: It was determined that positive perceptions of workgroup safety climate, as a higher order factor, comprised of supervisor support, horizontal cohesion, and vertical cohesion, was positively associated with seat belt use within a sample of firefighters. Organizational level safety climate did not have a significant relationship with seat belt use but did positively influence workgroup safety climate perceptions. CONCLUSIONS: Safety climate has been associated with safety compliance and participation behaviors, but more research was needed to specifically examine the impact of safety climate on seat belt use in firefighters. The findings point to the importance of safety climate as a leading indicator and predictor of seat belt use. Bolstering safety climate through safety programs, commitment to safety, effective communication, supportive supervisors and cohesion should ultimately aid in bolstering seat belt use among firefighters, which is important to curtailing firefighter injuries and fatalities.

The association between PTSD symptom clusters and religion/spirituality with alcohol use among first responders.

Alcohol misuse and posttraumatic stress disorder (PTSD) co-occur at high rates among first responders (e.g., law enforcement, firefighters, paramedics), underscoring the need to better understand these relations to inform intervention efforts. Identifying malleable processes relevant to the association between PTSD and alcohol among first responders could inform tailored interventions. An example of such a malleable process is spirituality. As such, the current study examined the unique relationships between PTSD symptom clusters and alcohol misuse, while also accounting for the role of select demographics and religion/spirituality, in a sample of first responders. A national online sample of first responders (N = 320) completed measures of PTSD symptomology, alcohol misuse, religion/spirituality and demographics. Hierarchical linear regression analyses revealed that PTSD Intrusion (Cluster B) symptom severity was associated with greater alcohol misuse and PTSD Avoidance (Cluster C) was associated with lower alcohol misuse. Additionally, positive and negative spiritual coping were also associated with alcohol misuse. In the context of similar research among military samples, findings suggest potentially unique associations between PTSD symptom clusters and alcohol misuse among first responders. Additionally, findings highlight the potentially protective role of religion/spirituality in this population. Future research should explore nuanced relationships between PTSD symptom clusters and alcohol misuse as well as the salience of spirituality/religion in this unique population.

Problems of operation of positive pressure ventilators on the basis of surveys of Polish officers of the State Fire Service.

Positive pressure ventilators (PPV) used by 97.7% of officers of the National Fire Service in Poland, are characterized by work that is not in line with the expectations of the firefighters. In order to improve the technical and operational features of these devices, a survey was conducted among 25,000 eligible firefighters, identifying the application of these devices, problems in use and expected development directions. A total of 682 officers voluntarily completed the survey. Based on their findings, it was determined that ventilators are most often used to smoke out buildings after or during a fire. Mentioned problems when using these devices were mainly noise (78.2%), exhaust emissions (68.5%), and impediments to mobility through the device's relatively heavy weight (40.2%). Other inconveniences were mentioned by less than 20% of firefighters. Polish firefighters expect the development of these devices mainly in terms of the above-mentioned features (noise reduction (81.7%) and reduction of the weight and size of the ventilators (about 50%)). Other expectations relate to the improvement of smoke removal in buildings: increasing the efficiency of smoke removal (46.4%) and efficiency regarding the rate of smoke removal in a building by increasing the size of the incoming airflow from the building's surroundings (33.2%). About 15% of firefighters expect changes in the operation of the ventilator itself, that is, an increase in the effective operating time (electric ventilators) and an increase in the device's uptime. The aim of the article is to identify the issues encountered during the operation and to indicate the expected direction of development for PPV by users. This information can be used by engineers to initiate new development work on these devices.

Characterization of fire investigators' polyaromatic hydrocarbon exposures using silicone wristbands.

BACKGROUND: Exposures to polyaromatic hydrocarbons (PAHs) contribute to cancer in the fire service. Fire investigators are involved in evaluations of post-fire scenes. In the US, it is estimated that there are up to 9000 fire investigators, compared to approximately 1.1 million total firefighting personnel. This exploratory study contributes initial evidence of PAH exposures sustained by this understudied group using worn silicone passive samplers. OBJECTIVES: Evaluate PAH exposures sustained by fire investigators at post-fire scenes using worn silicone passive samplers. Assess explanatory factors and health risks of PAH exposure at post-fire scenes. METHODS: As part of a cross-sectional study design, silicone wristbands were distributed to 16 North Carolina fire investigators, including eight public, seven private, and one public and private. Wristbands were worn during 46 post-fire scene investigations. Fire investigators completed pre- and post-surveys providing sociodemographic, occupational, and post-fire scene characteristics. Solvent extracts from wristbands were analyzed via gas chromatography-mass spectrometry (GC-MS). Results were used to estimate vapor-phase PAH concentration in the air at post-fire scenes. RESULTS: Fire investigations lasted an average of 148 minutes, standard deviation ± 93 minutes. A significant positive correlation (r=0.455, p<.001) was found between investigation duration and PAH concentrations on wristbands. Significantly greater time-normalized PAH exposures (p=0.039) were observed for investigations of newer post-fire scenes compared to older post-fire scenes. Regulatory airborne PAH exposure limits were exceeded in six investigations, based on exposure to estimated vapor-phase PAH concentrations in the air at post-fire scenes. DISCUSSION: Higher levels of off-gassing and suspended particulates at younger post-fire scenes may explain greater PAH exposure. Weaker correlations are found between wristband PAH concentration and investigation duration at older post-fire scenes, suggesting reduction of off-gassing PAHs over time. Exceedances of regulatory PAH limits indicate a need for protection against vapor-phase contaminants, especially at more recent post-fire scenes.

Spirituality/Religion Among First Responders With and Without Posttraumatic Stress Disorder and Alcohol Misuse.

Objective: To examine the co-occurrence of alcohol misuse and posttraumatic stress disorder (PTSD) and potential sources of coping (e.g., spirituality/religion) and clinically relevant variables among first responders (e.g., firefighters, law enforcement corrections officers, paramedics). Method: We assessed rates of independent and co-occurring alcohol misuse and PTSD among a national online sample of 320 first responders as well as the prevalence and salience of S/R, guilt, shame, moral injury, aspects of S/R, and treatment interest. Results: In our sample, 46.88% (n = 150) met criteria for comorbid alcohol misuse and probable PTSD and individuals with these comorbid conditions reported significantly greater negative religious coping, moral injury, and shame than all other diagnostic groups (i.e., independent alcohol misuse, independent PTSD, and neither). Correlations also revealed significant relationships between alcohol misuse and PTSD symptomatology with positive and negative religious coping, moral injury, shame, guilt, interest in treatment, and interest in spiritually integrated treatment. Conclusions: Findings highlight the high rates of independent and co-occurring alcohol misuse and PTSD among first responders as well as the salience of S/R in this population.

Sorption Processes of Selected PAHs on Selected Fire-Resistant Materials Used in Special Firefighter Clothing.

Fires constitute a significant threat due to the pollutants emitted and the destruction they cause. People who take part in firefighting operations must be equipped with appropriate tools, including special clothing that will allow them to work and guarantee safety. One of the threats is represented by compounds from the PAH (Polycyclic Aromatic Hydrocarbons) group, which are characterized by high toxicity and carcinogenicity. Therefore, it is important that the materials used constitute a barrier to contamination. Various materials from which individual elements of special firefighter's clothing are made were tested. Additionally, the effect of height on the possibility of sorption of PAH compounds on a given type of material was analyzed. Based on the obtained analysis results, it was found that both the type of material and the zone in which the clothing items are used are important in the sorption processes of pollutants. For example, PAHs with high molecular weight are most likely to settle on rubber, i.e., the material from which shoes are made, with the exception of Chrysene, whose presence was found primarily in aramid fibers, i.e., the material from which trousers and jackets are made. However, among PAHs with low molecular weight, compounds such as Methylnaphthalene,1- and Fluorene were sorbed on the rubber surface in large quantities. The only compound that is present in comparable amounts in all materials is Acenaphthylene. Data in this area may be important for taking further actions related to the modification of materials used in special fire brigade clothing and in their cleaning processes.

Strengthening First Responders' Coaching Proficiency through a Peer Fitness Leader Workshop: A Preliminary Efficacy Trial.

First responders require physical fitness to perform dangerous tasks in unpredictable environments. To promote physical fitness among first responders, many agencies use a peer fitness leader (PFL) approach; however, resources for the fitness, wellness, and health of PFLs are often minimal. This study's purpose was to investigate the effectiveness of a training workshop to increase PFL's training knowledge and coaching comfort (CC). Thirty-six PFLs (Experience: 14.6 ± 9.1 yrs; Age: 41.0 ± 9.8 yrs; BMI: 28.9 ± 7.0 kg·m-2) attended a one-day workshop. Paired samples t-tests assessed for differences between baseline and post-assessment knowledge scores. Pearson correlations described the bivariate relationship between baseline and post-assessment knowledge scores. Wilcoxon's Signed Rank Test determined associations between baseline and post-workshop CC variables. Spearman's Rho correlations described bivariate relationships between baseline and post-assessment values for each CC category. Kendall's Rank correlations investigated relationships between knowledge scores and total perceived CC for pre- and post-workshops. Statistical significance was set at p < 0.05. Results indicated an improvement from the baseline knowledge score (6.08 ± 1.46 points) and post-workshop knowledge score (7.03 ± 0.94 points); (t (25) = 3.85; p < 0.001). Similar trends were observed for all CC measures (Z > -3.42; p < 0.001). Differences were not observed between pre-workshop total CC and knowledge scores (τ = -0.03; p = 0.81) or following workshop completion (τ = -0.04; p = 0.76). Participants demonstrated varying exercise knowledge and CC, highlighting inconsistencies in exercise standards within first responder occupations. This investigation suggests the proposed pedagogy design may be a solution for agencies with limited budgets.

Isokinetic Shoulder Strength and its Associations to Injury in Tactical Populations: A Critical Review.

The aim of this review is to evaluate existing isokinetic testing protocols for the shoulder in tactical occupations, document their shoulder strength profiles, and determine any associations to shoulder injury. Four electronic databases were searched (Medline/Pubmed, Ovid/Emcare, CINAHL/Ebsco and Embase) using the keywords police OR law enforcement, firefighter, military, AND isokinetic. Articles were eligible if they had at least one cohort of a tactical population and included isokinetic testing of the glenohumeral joint. The search yielded 275 articles. After screening for duplicates and inclusion criteria, 19 articles remained for review, six of which assessed injury correlation. 17 articles evaluated military personnel and two examined firefighters. Articles were categorized by study design, population, isokinetic protocols, strength outcome measures and statistical measures. Concentric internal rotation (IR) and external rotation (ER) strength at 60 degrees/second were reported most frequently (84% of cases). There was a paucity of testing speeds, repetition ranges and contraction types evaluated when compared to existing literature in other populations with high shoulder injury occurrence such as overhead and collision athletes. Outside of military cohorts, there is limited data available to characterise the isokinetic strength profile of the shoulder in tactical occupations. Meta-analysis for injury association was unable to be performed due to independent variable and statistical heterogeneity. However, a best evidence synthesis suggested conflicting evidence to support the association of injury with isokinetic strength testing in tactical populations. Future studies should prioritise prospective designs utilising variable speeds, repetition schemes and contraction types to better capture the dynamic occupational demands in tactical groups.

Using a Walking Test to Assess Firefighter Fitness.

Tactical populations face increased risk on the job, and it is known that firefighters have high levels of cardiac-related death. Aerobic fitness is a modifiable cardiac risk factor, but many fire stations lack the proper equipment to easily assess aerobic fitness levels of their firefighters. Additionally, many fire stations lack wellness programs to hold firefighters accountable for maintaining their fitness levels. Purpose: We assessed the validity of the submaximal 6-minute walk test (6MWT) as a measure of aerobic capacity compared to a maximal treadmill test and the submaximal Gerkin protocol. Methods: Twenty-four firefighters (19 male, 5 female, 34.8 ± 9.7 years; 38.1 ± 3.6 kg·m-2) completed the 6MWT, the submaximal Gerkin protocol, and a maximal treadmill test. Data were analyzed with Bland-Altman plots and correlation analysis. Results: We found equivalence between the 6MWT and directly measured VO2max and between the 6MWT and Gerkin protocol using Bland-Altman plots. In our cohort, the 6MWT underestimated VO2max (31.57 ml·kg-1·min-1) compared to directly measured VO2max (38.1 ml·kg-1·min-1) by 17% and to the Gerkin (40.48 ml·kg-1·min-1) by 22%. Conclusion: Considering its equivalence, using the 6MWT could be a more accessible way to quantify aerobic capacity in firefighters. Despite underestimation, having an easy to administer protocol may encourage more fire stations to assess pre- and post- fitness levels regularly.

A systematic review and meta-analysis of musculoskeletal disorders among firefighters.

INTRODUCTION: Due to the nature of their job, firefighters face many ergonomic risk factors and are exposed to several musculoskeletal disorders (MSDs). The aim of this systematic review and meta-analysis was to investigate the prevalence of MSDs among firefighters. MATERIALS AND METHODS: This study was conducted based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The literature search was conducted in the databases of PubMed, Scopus, Web of Science, Science Direct, SID, ISC and Google Scholar without applying a time limitation until the end of July 2022. The random effects model was used for meta-analysis, and the I2 index was used to check heterogeneity among studies. The data were analyzed using STATA version 14 software. RESULTS: The primary literature searches in the databases identified 1,291 articles, 26 of which were entered the meta-analysis stage after screening, study selection, and quality assessment, including 36,342 firefighters. Based on the results of a meta-analysis, the overall prevalence of MSDs among firefighters was 46.39% (95% CI: 32.45-60.32, I2 = 99.7%, P < 0.001). The prevalence of MSDs was also investigated at neck (18.36%), low back (34.32%), shoulder (18.68%), hands (7.43%), upper back (10.15%), knee (19.97%) and foot (6.66%). CONCLUSION: Considering the relatively high prevalence of MSDs among firefighters and their higher exposition to specific job-related risk factors of MSDs compared to other professions, it is suggested to provide firefighters with appropriate training, implement ergonomic interventions, and regularly screen them to reduce MSDs.

The effect of age on musculoskeletal injury compensation costs in South Australian professional urban firefighters: A cohort study.

BACKGROUND: Firefighting is recognised as a physically demanding occupation involving exposure to hazardous environments and activities. An aging workforce combined with the age-related decline in physical fitness may result in increased future workers' compensation expenditure for fire service organisations. OBJECTIVE: The objective of this research was to investigate the costs associated with musculoskeletal sprain and strain injury and the impacts of age and injury location on Workers' Compensation claims submitted by professional urban firefighters. METHODS: Claim rates, direct costs, and days lost were extracted from a professional Fire Service organisation's workers' compensation claim database for financial years between 2011 to 2018. RESULTS: The mean cost per claim increased with age, with a mean claim cost of the 60-70-year-old group over 10 times more than the 20-29-year-old group. The mean days lost per claim were also higher for claims submitted by firefighters aged over 50. CONCLUSIONS: Older firefighters miss more workdays when injured and are associated with increased claims costs, particularly those in the 60-70-year group. With an aging workforce, Fire Service organisations must implement appropriate management and prevention strategies to reduce the potential risks associated with an aging workforce.

Investigating the influencing factors and prediction models of skin burns for firefighters' occupational safety.

Relevant studies in the fields of fire safety, occupational health and firefighter clothing were analyzed in this study to address the high injury rate among firefighters during fire rescue and the complexity of factors affecting skin burns. The findings indicate that the degree of skin burns in firefighters is primarily influenced by the heat source (heat flux, type), firefighter clothing (fabric, pattern) and the under-clothing air gap (thickness, characteristics). Since skin burns cannot be directly measured, internal skin heat transfer and burn prediction models are commonly employed to assess the impact of external factors on skin burns. These models can predict the safe working distance or time for firefighters. Investigating the influencing factors and prediction models of skin burns among firefighters holds significant value in enhancing operating procedures, optimizing firefighter clothing design and effectively preventing skin burns.

Meta-Analysis of Incidence and Mortality of Firefighter Cancer: An Update on Emerging Science.

BACKGROUND: Firefighters are faced with a broad range of toxic exposures during their work, including known and suspected carcinogens. The current study is an update to the previously published meta-analysis of cancer risk among firefighters by Soteriades and colleagues, and focuses on studies published from 2008 to 2020. METHODS: A comprehensive search of the literature was conducted, including electronic databases and bibliographies of recently published papers. Analyses include stratification of studies conducted in the United States (US) versus other countries. Cancer incidence and mortality rates were compared to the relevant general population. Random effects models were used to calculate summary risk estimates and their 95% confidence intervals. RESULTS: A total of 24 studies were included in the meta-analysis. Among the 42 cancer types covered, incidence was associated with firefighting in US samples for colon, kidney, large intestine, pleura, and prostate cancer, as well as malignant melanoma. There was an increased incidence of Hodgkin's Disease and malignant melanoma and a significantly lower risk of kidney cancer for non-US samples. Significant cancer mortality estimates for US samples included oral/buccal/mouth, other parts of the buccal cavity, pharynx, colon, esophagus, large intestine, lung, Non-Hodgkin's Lymphoma, pancreas, pleura, rectum, and soft tissue sarcoma. No cancer had a significantly higher rate of mortality among non-US samples. CONCLUSIONS: The findings underscore the global cancer burden among firefighters, and indicate that geographically stratifying studies afford a more nuanced risk perspective. Further research should investigate why US firefighters exhibit higher cancer mortality rates compared to international counterparts.

The 2nd Alarm Project: Bridging Social Work and Public Health to Improve Mental Wellness in the Fire Service.

Firefighters are trained to respond to a wide range of emergencies, and over the course of responding to emergencies, are exposed to a variety of potentially traumatic events. Repeated exposure to traumatic events may adversely impact firefighters' mental health. Combined with stigma surrounding help-seeking, lack of systematic resources and referral programs, and other barriers to care, firefighters do not routinely receive a continuum of trauma informed, assessment and treatment services from trained professionals. The purpose of this paper is to describe an evidence-informed approach to a reciprocal, collaborative model among social work and public health practice, policy, and research; and to offer a framework for researchers, clinicians, and policy advocates to more effectively achieve goals of preventing and treating trauma exposure in firefighters. This paper provides a comprehensive literature review, as well as describes a case study of a successful public health intervention for mitigating exposure to trauma among a population of firefighters. The significant contribution of mental health issues to the burden of disease among our firefighters is a matter of considerable public health concern. Effective approaches to mitigating behavioral health needs must bridge both mental health disciplines and public health to minimally, include access to evidence-based assessment and treatment, peer support capacity building, widely available mental health education, and leadership development to promote culture change. When considering a model for services with firefighters, reciprocal collaboration among researchers, health care professionals, first responder organizations, families, and other relevant community stakeholders is essential for success.

The Effect of Mandatory Fitness Requirements on Cardiovascular Events: A State-by-State Analysis Using a National Database.

BACKGROUND: Cardiovascular events are known to be the leading cause of death among on-duty firefighters. Implementing fitness standards may help reduce the incidence of cardiovascular deaths; however, standards vary between firefighter type and states. We aimed to investigate the rate of cardiovascular events among firefighters across states. METHODS: Using publicly available data from the United States Fire Administration, we explored the rates of cardiovascular deaths between firefighter type (e.g., career, volunteer, and wildland) and state. Specifically, we examined rates of cardiovascular deaths between California and Tennessee, which have fitness standards for all firefighters, and New York, which does not have fitness standards for volunteer firefighters. We used descriptive statistics and trend analysis to examine the data. FINDINGS: Most cardiovascular events occur among volunteer firefighters (60.6%, n = 877). Volunteer firefighters had 7.5 (95% CI = [4.8, 11.7], p < .001) greater odds of cardiovascular events compared to wildland firefighters, who had the lowest incidence of cardiovascular events (1.7%, n = 24). New York reported the most cardiovascular events (n = 161), primarily among volunteer firefighters (73.9%, n = 119). After the passage of legislation mandating fitness standards in California, a downtrend in the number of volunteer firefighter fatalities is observed. However, a null effect was observed in Tennessee after the passage of similar fitness standards as in California. CONCLUSIONS/APPLICATIONS TO PRACTICE: Volunteer firefighters are significantly more likely to die of a cardiovascular event than career and wildland firefighters, both of which have stricter fitness standards. However, the effect of legislation mandating stricter fitness standards among volunteers did not produce a clear benefit for preventing fatalities. Nurses need to promote cardiovascular health among volunteer firefighters.

Supporting emergency service workers to cope with critical incidents that can lead to psychological burden at work - developing skills in the Post Critical Incident Seminar: a qualitative interview study.

BACKGROUND: Emergency service workers face critical incidents causing psychological burden. This qualitative study investigates how attending a Post Critical Incident Seminar could affect the skills of emergency service workers to overcome incidents that can cause psychological burden at work and their consequences with the following research questions: (1) How did attending the Post Critical Incident Seminar impact the skills to overcome work incidents that can lead to psychological burden? and (2) How have these skills been manifested since attending the Post Critical Incident Seminar? METHODS: The data consists of individual interviews with fifteen emergency services workers who attended a Post Critical Incident Seminar in April 2021 in Finland. The interviews were conducted six months after the Post Critical Incident Seminar and analysed using inductive content analysis. RESULTS: The results of the first research question formed two main categories: improved performance abilities and improved self-regulation abilities. From the results of the second research question two main categories were created: new kind(s) of well-being and readiness to help. Several upper categories and sub-categories were discovered. CONCLUSIONS: Based on the results, attending a Post Critical Incident Seminar may be effective in developing skills to overcome critical incidents that can lead to psychological burden. Further follow-up studies should investigate how acquired skills from the Post Critical Incident Seminar practically affect emergency service workers and their well-being in the longer term.
