Public safety personnel (PSP), including correctional workers, firefighters, paramedics, police, and public safety communicators, are at increased risk for posttraumatic stress injury, yet face barriers in receiving timely support. Mobile health (mHealth) applications (apps) offer promising avenues for confidential, on-demand access to relevant information and support. The purpose of this study was to assess implementation of PeerOnCall, a new mHealth platform designed by and for PSP (the platform includes two parallel apps: one for frontline workers and one for peer support providers). A multi-site mixed methods implementation trial was conducted over 3−6 months in 42 public safety organizations across Canada. App usage trends were tracked through software analytics, and facilitators and barriers to app use were explored via interviews with organizational champions. Over 11,300 employees across 42 organizations were invited to use the PeerOnCall app over the trial period, with approximately 1759 PSP (15% of total) downloading the app. Variation within and across sectors was evident in app downloads and feature use. Approaches to communication (mode, timing, and messenger), and organizational culture related to mental health and help outreach affected uptake levels. PeerOnCall is a promising tool to facilitate access to peer support; however, culturally relevant strategies are needed to overcome barriers and integrate this tool into workplace practices.

Background/Objectives: Violence is a significant occupational health issue for paramedics, yet underreporting limits efforts to identify and mitigate risk. Leveraging a novel, point-of-event violence reporting system, we aimed to identify characteristics of 9-1-1 calls associated with an increased risk of violence in a single paramedic service in Ontario, Canada. Methods: We retrospectively analyzed all electronic violence and patient care reports filed by paramedics in Peel Region and used logistic regression to identify call-level predictors of any violence and, more specifically, physical or sexual assault. Results: In total, 374 paramedics filed 974 violence reports, 40% of which documented an assault, corresponding to a rate of 4.18 violent encounters per 1000 9-1-1 calls. In adjusted models, the risk of violence was elevated for calls originating from non-residential locations (e.g., streets, hotels, bars), occurring during afternoon or overnight shifts, and involving young or working-age males. Presenting problems related to intoxication, mental health, or altered mental status were strongly associated with increased risk, with particularly high adjusted odds ratios for assault. Conclusions: These findings support the utility of near-miss and violence surveillance systems and highlight the need for multidisciplinary crisis response to high-risk calls, especially those involving mental health or substance use.

The evolving role of paramedics presents a unique opportunity to enhance care for people who use drugs, a population disproportionately affected by systemic barriers and inequities. In fragmented healthcare systems, paramedics are well-positioned to improve access through initiatives such as social prescribing and harm reduction. This theory-driven commentary explores how Network Theory and Actor Network Theory provide valuable theoretical underpinnings to conceptualize and strengthen the integration of paramedics into care networks. By emphasizing the centrality of paramedics and their connections with both human and non-human actors, these theories illuminate the relational dynamics that influence effective care delivery. We argue that leveraging paramedics’ positionality can address gaps in system navigation, improve patient outcomes, and inform policy reforms. Future work should examine the roles of other key actors, strengthen paramedic advocacy, and identify strategies to overcome barriers to care for people who use drugs. Full article

Achieving health equity for people with disabilities requires addressing the barriers that they face when accessing healthcare. Older adults with disabilities may experience compounded disparities, yet little research has explored their satisfaction with health facility personnel, including non-healthcare staff. This study examines differences in satisfaction with health facility personnel between younger (18–59 years) and older (60+) adults with disabilities in Chile. Data from the 2024 Disability and Citizenship (DISCA) survey were analysed using chi-square tests to examine differences between younger and older people with disabilities with regard to their satisfaction with health facility personnel. Ordered logistic regressions were employed to predict high satisfaction, given socioeconomic and health-related variables. Findings indicated that a higher percentage of older adults with disabilities reported high satisfaction with health facility personnel compared to younger adults. Ordered logistic regressions confirmed that older adults had greater odds of reporting high satisfaction with doctors (OR: 3.83), other health professionals (OR: 4.66), paramedical technicians (OR: 4.31), and administrative staff (OR: 3.13). These results suggest that age influences satisfaction levels among people with disabilities, potentially due to varying expectations, experiences, or interactions with health facility personnel. Understanding the underlying reasons for these age-related differences is essential to inform policies and practices that ensure equitable, person-centred care for people with disabilities across the life course.

Introduction: Supraglottic airway devices play an important role in airway management in both pre-hospital as well as in-hospital settings. They are a well-recognised alternative to definitive airways in current medical practice. However, despite their wide use in clinical practice, little is known about their performance in patients with restricted access. This study aims to evaluate the time required to insert a supraglottic airway device and achieve a successful ventilation of four different devices in a simulated condition of an entrapped trauma patient with simultaneous cervical spine immobilisation. The ease-of-use and first-attempt success rate were also assessed. Methods: Fully qualified paramedics participated in this randomised, controlled manikin trial. A manikin with the cervical collar on was placed on the driver’s seat of a passenger car. Access to the manikin was only allowed from the front. The I-gel, the SLIPA, the LMA Supreme, and the Ambu AuraGain were evaluated. The time required to insert the device and achieve successful ventilation was recorded. The first-attempt success rate and the ease-of-use by the operator were also assessed. Results: The LMA Supreme required the shortest mean time to insert and ventilate the manikin, 10.5 s (±1.7) vs. 16.4 s (±8.4), p < 0.001. The use of the LMA Supreme was associated with the highest first-attempt success rate—88%. The SLIPA device outperformed all other studied devices with regard to ease-of-use and user-friendliness. Its mean score was 8.3 out of 10. Conclusions: The LMA Supreme was superior in terms of both the insertion-to-ventilation time as well as the first-attempt success rate. The SLIPA device was found to be easier to use and more user-friendly. Full article

Public safety personnel (PSP) are known to experience difficult and demanding occupational environments, which were further complicated by the COVID-19 crisis. While public safety research typically focuses on the impact of operational stressors on PSP functioning and wellbeing, relatively less is known about the types and impacts of organizational stressors and how all these affect social wellbeing during the pandemic. The current study surveyed Canadian firefighters (n = 123), paramedics (n = 246), and public safety communicators (n = 48) that continued to serve the public over the course of the pandemic. Participants responded to two open-ended survey questions about how COVID-19 affected their lives at work and home. Using an inductive thematic analysis approach, responses were coded to identify emergent, data-driven themes while drawing on existing theory for analysis. Across occupational groups, qualitative analyses revealed that the public safety measures imposed by the COVID-19 pandemic further exacerbated existing operational and organizational strains, including increased exposure to distressing calls, absenteeism and coping with alcohol, and a lack of support from management. Participants also identified financial strain and housing insecurity as stressors, as well as frustration and helplessness at others’ non-compliance with public health advisories and protocols. Communication surrounding the rationale behind government decision-making, the efficacy of serology tests, and rates of infection were also identified. Together, these findings offer a nuanced understanding of the interplay among operational, organizational, and social stressors experienced by Canadian PSP during the COVID-19 pandemic, illuminating their impact on mental health and wellbeing, and identifying targeted areas of focus for future planning and meaningful intervention to support PSP wellness.

Background: Paramedics and firefighters frequently encounter critical incidents that require both deep learning and emotional processing. This study investigates how reflective writing facilitates these processes, addressing the need to understand professional development in high-stress environments. Methods: The research analyzed reflective writings from 57 second-year Management of Catastrophe Defense undergraduates who were active emergency service workers. Using Mayring’s qualitative content analysis, the study examined participants’ descriptions of critical workplace incidents, emotional responses, and long-term impacts. The theoretical framework combines Paul’s concept of transformative experiences, Schön’s reflective practice, and Jarvis’s experiential learning theory. Results: The analysis revealed three key dimensions: transformative experiences, the role of conversation with the situation in meaning making and the significance of whole-person learning in understanding emotional presence and absence, and the role of reflective writing in understanding learning processes. The study uncovered complex patterns in how professionals process critical incidents and manage emotions in high-stress environments. Conclusions: Reflective writing serves as an effective tool for processing experiences and developing professional resilience, although the process of engaging with traumatic memories through reflection presents its own complexities. These insights contribute to the understanding of learning processes and professional development in high-stress environments. Full article

Background/Objectives: Acute obstructions of the upper respiratory tract are emergencies that may require a cricothyrotomy as ultima ratio. For this, precise identification of the conic ligament is essential. Point-of-care ultrasound (POCUS) offers a reliable tool for anatomical localization in challenging cases and could be used by a range of emergency medicine workers. This prospective, controlled observational study assesses the development of competencies of paramedics (PMs) in point-of-care ultrasound (POCUS) assisted identification of the conic ligament after structured training, and compares their competence level to emergency physicians (EPs). Methods: PMs and a control group of EPs received an identical structured training program as part of an ultrasound course. It included a 10-min theoretical introduction, a 10-min video, and a 45-min practical session with ultrasound devices. Questionnaires and a practical test assessed both group’s previous experiences, satisfaction with training, and the development of subjective and objective competencies before (T₁) and after (T₂) the training. Results: A total of 120 participants (N = 92 PMs and N = 28 EPs) participated. A minority had previously performed a cricothyrotomy even in training settings (PMs 17%; EPs 11%), and none had identified the conic ligament using POCUS. The study group’s subjective and objective competencies increased significantly (p < 0.001). At T2, the study group demonstrated comparable subjective (p = 0.22) and objective (p = 0.81) competencies to those of the control group. The study group needed significantly (p < 0.01) less time to perform the DOPS. While both groups were satisfied with the study material (PMs 2.2 ± 1.2 vs. Eps 1.6 ± 1.0; p = 0.02) and the training (PMs 1.8 ± 1.0 vs. EPs 1.4 ± 0.7, p = 0.03), the study group rated both significantly better. Conclusions: After structured training, paramedics successfully identified the conic ligament using POCUS comparably to emergency physicians. Integrating POCUS into paramedic training may improve prehospital airway management and enhance patient safety. Further studies should investigate long-term skill retention and real-life application.

Liver cirrhosis continues to be a major global health issue, contributing to high morbidity and mortality due to its progressive nature and associated complications. This review explores recent advancements in the diagnosis and treatment of liver cirrhosis and its related syndromes. Non-invasive diagnostic tools, such as elastography and serum biomarkers, have significantly improved early detection, reducing the need for liver biopsies. Advanced imaging techniques, including MRI and CT, further enhance diagnostic accuracy. In parallel, molecular and genomic research is providing new insights into the pathogenesis of the disease, paving the way for precision medicine. On the treatment front, pharmacological innovations, such as antifibrotic agents and targeted therapies, show promise in slowing disease progression. Endoscopic interventions like variceal banding are improving the management of complications, while advancements in liver transplantation and artificial liver support systems offer life-saving alternatives. Regenerative medicine, particularly stem cell therapy and tissue engineering, is emerging as a promising strategy for liver repair. Managing cirrhosis-related syndromes, including portal hypertension, ascites, hepatic encephalopathy, and hepatorenal syndrome, now involves evolving therapeutic approaches such as transjugular intrahepatic portosystemic shunt (TIPS) and novel pharmacotherapies. Prognostic scoring systems like the MELD and Child–Pugh are being refined with new biomarkers for better risk stratification. The future of cirrhosis care will likely involve the integration of artificial intelligence and machine learning for early diagnosis and personalized treatments, alongside emerging therapies currently under investigation. Despite these advancements, challenges such as costs, accessibility, and healthcare disparities remain barriers to widespread adoption. This review highlights the importance of incorporating innovative diagnostic and therapeutic strategies into clinical practice to improve the outcomes for patients with liver cirrhosis and its complications.

Background/Objectives: Performing cardiopulmonary resuscitation (CPR) is cognitively demanding, often requiring helpers to perform cognitive and manual tasks simultaneously. While the human brain primarily switches between tasks rather than processing them simultaneously, it remains unclear whether performing repetitive, monotonous manual tasks, such as chest compressions, affects cognitive performance. This study aimed to assess the impact of chest compressions on mental arithmetic performance. Methods: In a randomized crossover trial, healthy participants trained in advanced life support (physicians, nurses, and paramedics) completed the Paced Auditory Serial Addition Test (PASAT) under two conditions: with or without performing chest compressions on a manikin. The primary outcome was the number of correct PASAT answers. Secondary outcomes included workload assessment using the NASA Task Load Index (TLX) and chest compression (CC) performance. The trial was registered at clinicaltrials.gov and approved by the local ethics committee. Results: Thirty-eight participants were included. The number of correct PASAT responses was significantly lower during chest compressions compared to the control (36.5 vs. 41; p < 0.01). NASA TLX values were significantly higher in the chest compression condition, indicating increased perceived workload. Chest compression performance showed statistically significant differences between a phase of just chest compressions and during the PASAT, especially increased levels of incomplete recoil. Conclusions: This study demonstrates that even a simple repetitive motor task like chest compressions impairs cognitive task performance significantly. Furthermore, multitasking was shown to decrease chest compression quality. These findings strongly highlight the importance of effective task allocation and minimizing multitasking during CPR to optimize performance and thereby patient outcomes. Full article

AI-driven approaches hold great promise for a more personalized, efficient, and effective future in HIV treatment and care. Full article

Cystic fibrosis (CF) is a multisystemic disease caused by a genetic defect, namely a mutation in the CFTR gene, that results in the production of an abnormal protein that regulates the flow of chloride ions through epithelial cells, leading to the dehydration of secreted mucus and changes in its biological properties. Chronic inflammation and recurrent respiratory infections progressively damage lung tissue, leading to respiratory and cardiorespiratory failure. This study aims to present a clinical case and explore the clinical changes in CF that may influence the provision of pre-hospital first aid. The study presents a case report of a 23-year-old CF patient undergoing evaluation for lung transplantation, infected with Pseudomonas aeruginosa and Staphylococcus aureus with the MSSA phenotype, and in a severe condition due to infectious exacerbation. Despite antibiotic treatment, the patient’s condition deteriorated, leading to respiratory failure and cardiac arrest. Emergency measures were taken to maintain airway patency—the patient was sedated, intubated, and connected to a ventilator. CF involves systemic complications that, during exacerbations, may require urgent interventions. Cystic fibrosis is associated with multiple systemic complications, some of which may, during exacerbations, require emergency medical interventions. Providing care to this patient group involves specific procedures addressing the consequences of the underlying disease. Due to increasing survival rates and the emergence of new phenotypes, there is a need for the continuous education of medical personnel, including emergency responders, regarding the management of genetically determined diseases. This study underscores the importance of recognizing CF’s complex nature and adapting emergency care accordingly to ensure timely and effective intervention in life-threatening situations.

Background/Objectives: Emergency Medical Services (EMS) clinicians in the US have high COVID-19 vaccine hesitancy rates and often do not receive primary vaccinations or subsequent boosters. The extent of booster attrition following initial vaccination and first booster dose in EMS clinicians is unknown. Our objective was to evaluate the prevalence and drivers of COVID-19 booster attrition in EMS clinicians. We hypothesized that booster attrition is common among EMS clinicians and associated with various EMS characteristics. Methods: This study was a cross-sectional analysis of nationally certified civilian EMS clinicians aged 18–85 years old. An electronic survey was distributed, which included an evaluation of vaccination status, booster acceptance, willingness to receive future boosters, perceived risk of contracting COVID-19 from the Understanding America Survey (8 items), and mistrust of healthcare organizations using the Medical Mistrust Index (MMI) (7 items). These data were combined with demographic and work-related characteristics from the National Registry of EMTs dataset. A multivariable logistic regression model (OR, 95% CI) was used to describe booster attrition associations between demographics, work-related characteristics, perceived risk, and medical mistrust. Results: A total of 1902 respondents met initial inclusion criteria. Within this group, 78% were COVID-19 vaccinated, and an additional 65% received a booster. Of these, 37% reported not planning to receive any other booster treatments following the first booster. Primary reasons for not continuing with subsequent boosters include confusion among experts on efficacy (59%), severe side effects (38%), the belief that COVID-19 is not a threat (26%), the belief in natural immunity (25%), and the belief that boosters are not required (23%). Odds of planning to receive another booster increased with receiving a flu vaccine (5.03, 3.08–8.22) and urban environment (1.96, 1.19–3.24, referent rural). In comparison, the odds of planning to receive another booster were lower for paramedics (0.56, 0.38–0.83, referent EMT) and fire agencies (0.53, 0.31–0.89, referent hospital). As the perceived risk of COVID-19 and medical mistrust decrease, the odds of planning to receive another booster increase (perceived risk: 1.98, 1.41–2.78; trust: 4.12, 3.21–5.28). Conclusions: The rate of booster attrition following receipt of one booster is high, at 37%. While there are associations with EMS demographic and workforce characteristics, further exploration is necessary to define the drivers and potential consequences of high booster attrition in the EMS clinician community.

Background: Demand for Hamburg’s ambulance rescue system (ARS) in Germany, which is managed by the fire service, increased by more than 10% between 2019 and 2021. This increase was mainly driven by a more than 20% increase in non-critical ambulance rescues, while critical rescues decreased over the same period. Factors contributing to this trend include demographic changes, longer waiting times in primary care and declining quality in out-of-hospital care. To address this issue, the introduction of community emergency paramedics (CEPs)—who provide treatment and advice to patients at home before ambulance services are called—has been proposed as a potential solution to alleviate pressure on the ARS. Methods: In this study, 17 ARS stations in Hamburg, categorized into three operational areas (East, South, West), were analyzed using comprehensive statistical methods such as hypothesis testing, correlation analysis, regression modeling and clustering. Data from 2019 and 2021 were examined to assess the feasibility of integrating CEPs into the existing system. Results: Key findings identified specific stations with high potential for CEP support and optimal mission times (based on time of day, day of week and calendar week) to improve operational efficiency. The impact of regulatory measures introduced during the COVID-19 pandemic was also evident in the 2021 data. Conclusions: Finally, four policy scenarios—taking into account different synergy effects among the 17 stations—are presented, providing projections of the managerial and economic benefits for Hamburg policymakers. These policy implications aim to support the development of a robust CEP strategy to improve the overall efficiency and sustainability of the ARS. Full article

Background: Obstetric haemorrhage, particularly postpartum haemorrhage (PPH), remains a significant global health challenge and a leading cause of maternal mortality. Despite advancements in understanding and preventing PPH, haemorrhage remains a leading cause of maternal mortality worldwide. The aim of this study was to review the current literature on the use of uterotonic drugs, particularly oxytocin, in reducing perinatal mortality during prehospital deliveries. Methods: In December 2024, a comprehensive search was conducted across PubMed, Web of Science, Embase, and Scopus, yielding 108 records, of which four studies met the inclusion criteria. Results: The limited evidence underscores the need for targeted research and adherence to international obstetric guidelines to improve PPH management and maternal outcomes. In some countries, the only uterotonic drug available in all EMS teams is oxytocin; in others, there is none. Emergency Medical Services (EMS) play a critical role in providing lifesaving interventions during obstetric emergencies, often serving as the first and sometimes only point of medical contact for women experiencing complications during childbirth. Conclusion: There is a lack of high-quality clinical studies evaluating the effectiveness of uterotonic agents in EMS operations and their role in treating postpartum haemorrhage in prehospital settings. Addressing this gap requires targeted research to generate robust evidence and inform the development of standardized protocols. Such efforts could enhance the timely management of PPH, ultimately reducing maternal mortality and improving outcomes in resource-limited and prehospital environments. By bridging the evidence gap, EMS systems worldwide can be better equipped to handle obstetric emergencies effectively. Full article
