In the Nick of Time-Emergency Front-of-Neck Airway Access

Emergency front-of-neck access refers to all techniques that deliver oxygen into the airway lumen through the anterior neck structures and encompasses access both through the cricothyroid membrane and the tracheal wall. There has yet to be a universal agreement regarding the preferred technique. A surgical incision is currently the most common approach in prehospital and in-hospital care. This review intends to review and summarize the existing clinical, basic science, and societal guidelines for eFONA.

'Profound personal and professional impacts': A qualitative study of clinician experiences of a mental health disaster response to Australia's black summer bushfires

OBJECTIVE

To explore the experiences of clinician and management stakeholders involved in a rural/metropolitan collaborative mental health disaster response to the 2019-2020 Black Summer bushfires in the Snowy Valleys region of southern New South Wales (NSW), Australia.

SETTING

A mental health and drug health service in the Snowy Valleys region of rural NSW in collaboration with a mental health service from metropolitan Sydney, NSW.

PARTICIPANTS

Mental health clinicians and managers from a rural health district (n = 6) and a metropolitan health district (n = 8) involved in a collaborative disaster response to the 2019-2020 Black Summer bushfire disaster in the Snowy Valleys region of southern NSW, Australia.

DESIGN

An interpretive qualitative study design using semi-structured individual interviews, with transcripts analysed using Reflexive Thematic Analysis.

RESULTS

Thematic findings on participant experiences are presented under three organising constructs of before (stepping up and jumping right in), during (finding a rhythm of working together), and after (profound personal and professional impacts) the mental health disaster response.

CONCLUSION

Participant experiences had shared and distinct components before, during and after the mental health disaster response, culminating in profound personal and professional impacts. Findings highlight positive aspects and challenges for clinicians participating in a rural/metropolitan collaborative mental health disaster response. The findings of this study contribute new knowledge about experiences of mental health clinicians participating in a disaster response after bushfires, from dual perspectives of members of a bushfire-affected community and those responding from outside a bushfire-affected community, which may inform ongoing planning of responses to disaster in Australia.

Development and validation of assessment instruments for cervical collar and spinal board placement in simulated environments for nursing students in the care of polytrauma patients

BACKGROUND

Multiple trauma injuries are the leading cause of death and disability in people under the age of 45 and require prompt and specialised care. However, medical and nursing education programmes do not always include specific training in emergency pre-hospital care, resulting in a lack of basic practical skills in trauma management.

OBJECTIVE

To develop and validate two instruments for assessing nursing students' competence in cervical collar and spinal board application in simulated pre-hospital emergency scenarios.

METHOD

This is an instrumental study that involves the development of two assessment instruments and the evaluation of their psychometric properties in a sample of 392 nursing students. Content validity was assessed using expert judgement, by calculating the content validity ratio (CVR) for each item and the scale level content validity index average (S-CVI/Ave) for the instruments. Exploratory factor analysis using the MINRES extraction method and Promax rotation was performed to analyse the performance of the items and structure of the rubrics. Internal consistency was analysed using the Omega coefficient and inter-rater agreement was assessed using Cohen's Kappa coefficient.

RESULTS

Initially, two rubrics were obtained: one with six items for cervical collar placement (S-CVI/Ave = 0.86) and one with nine items for spinal board placement (S-CVI/Ave = 0.81). Both had a single-factor structure, with all items having factor loadings greater than 0.34 for the cervical collar rubric and 0.56 for the spinal board rubric, except for item 2 of the cervical collar rubric (λ = 0.24), which was subsequently removed. The final cervical collar rubric (five items) had an overall internal consistency of 0.84 and the spinal board rubric had an overall internal consistency of 0.90, calculated using the Omega statistic. The weighted Kappa coefficient for each item ranged from acceptable (0.32) to substantial (0.79). These results show that we have successfully developed two sufficiently valid instruments to assess the immobilisation competencies proposed in the objective of the study.

CONCLUSION

Whilst further research is needed to fully establish their psychometric properties, these instruments offer a valuable starting point for evaluating nursing students' competence in cervical collar and spinal board application in simulated pre-hospital scenarios.

Implementation of the Hospital Incident Command System during COVID-19 Pandemic; Experience from an Iranian Reference Hospital

Introduction: There is growing popularity of the Hospital Incident Command System (HICS) as an organizational tool for hospital management in the COVID-19 pandemic. We specifically describe implementation of HICS at the Isfahan province reference hospital (Isabn-e-Maryam) during the COVID-19 pandemic and try to explore performance of it. Methods: To document the actions taken during the COVID-19 pandemic, standard, open-ended interviews were conducted with individuals occupying activated HICS leadership positions during the event. A checklist based on the job action sheets of the HICS was used for performance assessment. Results: With the onset of the pandemic, hospital director revised ICS structure that adheres to span of better control of COVID-19. Methods of expanding hospital inpatient capacity to enable surge capacity were considered. The highest performance score was in the field of planning. Performance was intermediate in Financial/Administration section and good in other fields. Discussion: In the current COVID-19 pandemic, establishing HICS with some consideration about long-standing events can help improve communication, resource use, staff and patient protection, and maintenance of roles.

Paramedic educational programs maintain entry level competency throughout the COVID-19 pandemic

Objective

The COVID-19 pandemic required unprecedented changes to emergency medical services (EMS) educational frameworks in the United States. It is unclear if pandemic-related changes impacted paramedic educational outcomes. We aimed to evaluate curricular and performance changes resulting from the initial COVID-19 pandemic on paramedic educational programs.

Methods

We performed a retrospective cross-sectional evaluation of paramedic educational programs in 2019 and 2020 using the Committee on Accreditation of Educational Programs for the Emergency Medical Services Professions annual reports. These reports contain detailed program components and measures of program success. We included programs reporting at least one graduate in the study period. Descriptive statistics (proportions [%], median [interquartile range, IQR]) were calculated for paramedic program characteristics in 2019 and 2020, as well as pandemic specific curriculum changes. Wilcoxon rank-sum and Fisher's exact tests were used to evaluate differences in characteristics by year.

Results

The number of paramedic educational programs in our population decreased from 640 programs in 2019 to 612 in 2020, with a statistically significant decrease in clinical hours (2019: 219 [IQR 168‒272]; 2020: 200.5 [IQR 157‒261]). There was no difference in first or third-attempt certification examination success between years. Temporary shutdown was experienced in 34% of programs (duration: 3 weeks [2‒7]) and 72% of required curricular changes. Curricular changes commonly included decreased in-person education (86%), traditional classroom lectures (78%), number of clinical sites (78%), and increased online didactic education (92%). Only 20% of programs decreased laboratory simulation or total training hours.

Conclusion

During the pandemic, paramedic educational programs changed educational delivery with no observed differences on overall program performance. Identifying key curricular changes and best practices for implementation may be necessary to better optimize future educational delivery.

Emergency reflex action drill for traumatic cardiac arrest in a simulated pre-hospital setting; a one-group pre-post intervention study

BACKGROUND

Emergency Reflex Action Drills (ERADs) are meant to decrease stress-associated cognitive demand in high urgency situations. The aim of this study was to develop and test an ERAD for witnessed traumatic cardiac arrest (TCA), an event in which potentially reversible causes need to be systematically addressed and treated in a short period of time. We hypothesize that this ERAD (the TCA-Drill) helps ground Emergency Medical Services (EMS) nurses in overcoming performance decline during this specific high-pressure situation.

METHODS

This was a prospective, experimental one-group pre-post intervention study. Ground EMS nurses participated in a session of four simulated scenarios, with an in-between educational session to teach the TCA-Drill. Scenarios were video recorded, after which adherence and time differences were analyzed. Self-confidence on clinical practice was measured before and after the scenarios.

RESULTS

Twelve ground EMS nurses participated in this study. Overall median time to address reversible causes of TCA decreased significantly using the TCA-Drill (132 vs. 110 s; p = 0.030) compared with the conventional ALS strategy. More specifically, participants adhering to the TCA-Drill showed a significantly lower time needed for hemorrhage control (58 vs. 37 s; p = 0.012). Eight of 12 (67 %) ground EMS nurses performed the ERAD without protocol deviations. Reported self-confidence significantly increased on 11 of the 13 surveyed items.

CONCLUSIONS

The use of an ERAD for TCA (the TCA-Drill) significantly reduces the time to address reversible causes for TCA without delaying chest compressions in a simulated environment and can be easily taught to ground EMS nurses and increases self-confidence.

IMPLICATIONS FOR CLINICAL PRACTICE

The use of an ERAD for TCA (the TCA-Drill can significantly reduce the time to address reversible causes for TCA without delaying chest compression. This drill can be easily taught to ground EMS nurses and increases their self-confidence in addressing TCA-patients.

Treatment adherence: A Concept Analysis Using the Walker & Avant Method

Purpose

To clarify the meaning of treatment adherence and identify its attributes, antecedents, consequences, and empirical referents.

Design

A concept analysis.

Methods

Walker and Avant's method was used to analyze treatment adherence. PubMed, Web of Science, Wiley Online Library, and EBSCO databases were searched from 2013 to 2023. The PRISMA 2020 checklist was used.

Results

Seventeen studies were included in this analysis. The defining attributes were the ability to comply with the treatment, consistency in the treatment plan, communication with the healthcare provider, and willingness to treat. Antecedents included multiple medicines, lifestyle changes, illness perceptions and beliefs, and long-term treatment. The outcomes included treatment success, improved long-term treatment, and improved clinical outcomes.

Conclusion

Treatment adherence is a positive reaction of a patient to have the ability to comply with the treatment, consistency in the treatment plan, communication with the healthcare provider, and willingness to treat. This study proposes a detailed definition, attributes, antecedents, consequences, and empirical referents for treatment adherence. It is instructive to clinical nursing of treatment adherence, can be extended to various diseases, helps to improve clinical nursing practice regarding treatment adherence, and contribute to improving human health.

A survey of emergency medical service providers' perspectives regarding relatives influence on acute prehospital treatment of adult patients

BACKGROUND

In the field of prehospital emergency medicine, specialized emergency medical service (EMS) providers interact with acutely ill patients and their relatives. The influence of family presence during in-hospital resuscitation is well described. However, no studies have previously assessed the influence of relatives' presence in the acute prehospital setting. The aim of this study was to investigate EMS providers' perspectives on relatives' impact on the acute prehospital treatment of adult patients.

METHODS

An online anonymous survey was distributed to all prehospital EMS providers in the Capital Region of Denmark. The survey included 25 research questions on a 5-point Likert scale, investigating relatives' influence on treatment in three different domains: positive, negative, and resuscitation. A higher domain score indicates a high level of agreement or frequency.

RESULTS

Two hundred forty-six EMS providers completed the survey (84 ambulance technicians, 87 paramedics, and 75 physicians). There were no significant differences in the positive domain across professions (p = .175). Physicians had a statistically significant lower median score in the negative domain, compared with ambulance technicians and paramedics (2.50 vs. 2.63 and 2.63, p = .024). In the resuscitation domain, paramedics and physicians had a significant lower median score compared with ambulance technicians (3.00 and 3.00 vs. 3.14, p = .003).

CONCLUSION

All professions were equally positive towards the relatives' presence and involvement in the acute prehospital setting. Physicians were less likely to be negatively influenced by the presence of relatives compared with ambulance technicians and paramedics. In all professions, increased experience led to improved comfort with handling relatives.

Accuracy of a Commercial Large Language Model (ChatGPT) to Perform Disaster Triage of Simulated Patients Using the Simple Triage and Rapid Treatment (START) Protocol: Gage Repeatability and Reproducibility Study

BACKGROUND

The release of ChatGPT (OpenAI) in November 2022 drastically reduced the barrier to using artificial intelligence by allowing a simple web-based text interface to a large language model (LLM). One use case where ChatGPT could be useful is in triaging patients at the site of a disaster using the Simple Triage and Rapid Treatment (START) protocol. However, LLMs experience several common errors including hallucinations (also called confabulations) and prompt dependency.

OBJECTIVE

This study addresses the research problem: "Can ChatGPT adequately triage simulated disaster patients using the START protocol?" by measuring three outcomes: repeatability, reproducibility, and accuracy.

METHODS

Nine prompts were developed by 5 disaster medicine physicians. A Python script queried ChatGPT Version 4 for each prompt combined with 391 validated simulated patient vignettes. Ten repetitions of each combination were performed for a total of 35,190 simulated triages. A reference standard START triage code for each simulated case was assigned by 2 disaster medicine specialists (JMF and MV), with a third specialist (LC) added if the first two did not agree. Results were evaluated using a gage repeatability and reproducibility study (gage R and R). Repeatability was defined as variation due to repeated use of the same prompt. Reproducibility was defined as variation due to the use of different prompts on the same patient vignette. Accuracy was defined as agreement with the reference standard.

RESULTS

Although 35,102 (99.7%) queries returned a valid START score, there was considerable variability. Repeatability (use of the same prompt repeatedly) was 14% of the overall variation. Reproducibility (use of different prompts) was 4.1% of the overall variation. The accuracy of ChatGPT for START was 63.9% with a 32.9% overtriage rate and a 3.1% undertriage rate. Accuracy varied by prompt with a maximum of 71.8% and a minimum of 46.7%.

CONCLUSIONS

This study indicates that ChatGPT version 4 is insufficient to triage simulated disaster patients via the START protocol. It demonstrated suboptimal repeatability and reproducibility. The overall accuracy of triage was only 63.9%. Health care professionals are advised to exercise caution while using commercial LLMs for vital medical determinations, given that these tools may commonly produce inaccurate data, colloquially referred to as hallucinations or confabulations. Artificial intelligence-guided tools should undergo rigorous statistical evaluation-using methods such as gage R and R-before implementation into clinical settings.

Surplus value quantification of overdue medical devices based on Kohonen network algorithm

With the continuous updating and progress of medical equipment, the overdue medical device has problems such as management difficulties, resource waste, and potential security risks. Therefore, this paper used the Kohonen network algorithm to quantitatively evaluate and analyze the surplus value of overdue medical devices. In this paper, the Kohonen network algorithm was used to build a quantitative model of the surplus value of the overdue medical device, and the self-organization characteristics and data-driven learning ability of the Kohonen network were used to predict the surplus value of the equipment more accurately. Support vector machine was used to quantitatively evaluate and predict the surplus value of overdue medical devices, and further optimize the model performance, to provide more accurate and reliable decision support for medical equipment management. The Kohonen network algorithm used in this paper evaluated the correlation between the service life and maintenance cost of eight types of overdue medical devices and quantitatively predicted the surplus value of overdue medical devices with the random forest algorithm. According to the comparison of prediction bias, the maximum deviation between the expected surplus value and the actual surplus value is only 1, and the deviation value by the random forest algorithm is as low as 6, the Kohonen network algorithm in this paper has better prediction performance than the random forest algorithm. In the experiment of comparative analysis and verification by introducing the decision tree algorithm, the average error rate of the Kohonen network algorithm in this paper was only 20.57%, which was far lower than 46.34% of the random forest algorithm and 65.31% of decision tree algorithm. The Kohonen network algorithm used in this paper can effectively quantitatively evaluate and predict the surplus value of overdue medical devices, thus improving the efficiency of medical equipment management, reducing costs, and ensuring patient safety.

Selection of the Preferred Puncture Site on Manual Intraosseous Infusion: Proximal Humerus or Proximal Tibia?

Aims/Background Establishing an intraosseous infusion (IO) pathway can rapidly open an urgent route of drug administration for critically ill patients. This study aims to assess different puncture sites on the efficacy of manual intraosseous infusion. Methods Upon applying computed tomography (CT), we compared compact bone thickness and CT values at the same individual's proximal humerus and proximal tibia puncture sites (n = 40). Additionally, cadaveric experiments were used to compare the efficiency of manual puncture at two different insertion sites of the proximal humerus and proximal tibia in the same individual (n = 5). Results The compact bone thickness and CT values at the proximal humerus were significantly lower than those at the proximal tibia. The cadaveric experiments further confirmed that the proximal humerus was superior to the proximal tibia as an insertion site, indicating the proximal humerus is a more suitable insertion site for manual bone marrow puncture needles. Conclusion Selection of the puncture site markedly influences the effectiveness of manual intraosseous infusion, with the proximal humerus potentially offering better puncture efficacy than the proximal tibia.

Prehospital factors predicting mortality in patients with shock: state-wide linkage study

BACKGROUND

Patients with shock treated by emergency medical services (EMS) have high morbidity and mortality. Knowledge of prehospital factors predicting outcomes in patients with shock remains limited. We aimed to describe the prehospital predictors of mortality in patients with non-traumatic shock transported to hospital by EMS.

METHOD

This is a retrospective cohort study of consecutive ambulance attendances for non-traumatic shock in Victoria, Australia (January 2015-June 2019) linked with government-held administrative data (emergency, admissions and mortality records). Predictors of 30-day mortality were assessed using Cox proportional regressions. The primary outcome was 30-day all-cause mortality.

RESULTS

Overall, 21 334 patients with non-traumatic shock (median age 69 years, 54.8% female) were successfully linked with state administrative records. Among this cohort, 9 149 (43%) patients died within 30-days. Compared with survivors, non-survivors had a longer median on-scene time: 60 (35-98) versus 30 (19-50), p <0.001. Non-survivors were more likely to be older (median age in years: 74 (61-84) vs 65 (47-78), p<0.001), had prehospital cardiac arrest requiring cardiopulmonary resuscitation (adjusted HR (aHR)=6.26, 95% CI 5.87, 6.69) and had prehospital intubation (aHR=1.07, CI 1.00, 1.14). Reduced 30-day mortality was associated with administration of epinephrine (aHR=0.66, CI 0.62, 0.71) and systolic blood pressures above 80 mm Hg in the prehospital setting.

CONCLUSION

The 30-day mortality from non-traumatic shock is high at 43%. Independent predictors of mortality included age, prehospital cardiac arrest and endotracheal intubation. Interventions that target reversible causes of short-term mortality in patients with non-traumatic shock are a high priority.

Seeking a Treatable Cause of Out-of-Hospital Cardiac Arrest during and after Resuscitation

Out-of-hospital cardiac arrest (OHCA) represents a significant global public health burden, characterized by low survival and few established diagnostic tools to guide intervention. OHCA presents with a wide variety of etiologies in a heterogeneous population, posing a clinical challenge to care teams. In this review, we describe evolving research focused on diagnostic approaches to OHCA following resuscitation, including electrocardiography, coronary angiography, computed tomography, ultrasonography, and serologic biomarker assessment. These diagnostic tools have been employed in post-resuscitative efforts for diagnosing ischemic and non-ischemic cardiac, respiratory, neurologic, vascular, traumatic, and metabolic causes of arrest.

The effect of assessor visibility on student stress and anxiety in emergency care simulation assessments

BACKGROUND

Simulation assessment can result in anxiety for students. These assessments involve being observed by assessors, so there is a significant socio-evaluative stress component which may cause greater anxiety if assessors are visible to students during assessments. The aim of this study was to determine the effect of assessor visibility on biological and physiological markers of stress and levels of anxiety experienced by pre-hospital emergency care students in a simulation assessment environment.

METHODS

A paired comparison, pre-post test research design was used with two conditions; an assessor visible condition with simulation assessors visible to students in the room and an assessor not visible condition with assessors not in the room but connected via video link. With a sample of 29 emergency care students anxiety was measured with the State-Trait Anxiety Inventory and stress was measured with salivary cortisol and heart rate variability (HRV).

RESULTS

Differences in state anxiety scores, HRV variables and salivary cortisol suggested lower stress and anxiety in the assessor visible group. Only heart rate was significantly different between the groups (p = 0.016), with a higher heart rate in the assessor not visible group.

CONCLUSIONS

Greater stress and anxiety may be experienced by students during emergency care simulation assessments when assessors are not visible to students.

Exposing disparities in flood adaptation for equitable future interventions in the USA

As governments race to implement new climate adaptation solutions that prepare for more frequent flooding, they must seek policies that are effective for all communities and uphold climate justice. This requires evaluating policies not only on their overall effectiveness but also on whether they benefit all communities. Using the USA as an example, we illustrate the importance of considering such disparities for flood adaptation through a FEMA dataset of  ~ 2.5 million flood insurance claims. We use CAUSALFLOW, a causal inference method based on deep generative models, to estimate the treatment effect of flood adaptation interventions based on a community's income, racial demographics, population, flood risk, educational attainment, and precipitation. We find that the program saves communities $5,000-15,000 per household. However, these savings are not evenly spread across communities. For example, for low-income communities savings sharply decline as flood-risk increases in contrast to their high-income counterparts. Even among low-income communities, savings are >$6,000 per household higher in predominantly white communities. Future flood adaptation efforts should go beyond reducing losses overall and aim to equitably support communities in the race for climate adaptation.

Intranasal therapies for neonatal hypoxic-ischemic encephalopathy: Systematic review, synthesis, and implications for global accessibility to care

Neonatal hypoxic-ischemic encephalopathy (HIE) is the leading cause of neurodevelopmental morbidity in term infants worldwide. Incidence of HIE is highest in low and middle-income communities with minimal access to neonatal intensive care and an underdeveloped infrastructure for advanced neurologic interventions. Moreover, therapeutic hypothermia, standard of care for HIE in high resourced settings, is shown to be ineffective in low and middle-income communities. With their low cost, ease of administration, and capacity to potently target the central nervous system, intranasal therapies pose a unique opportunity to be a more globally accessible treatment for neonatal HIE. Intranasal experimental therapeutics have been studied in both rodent and piglet models, but no intranasal therapeutics for neonatal HIE have undergone human clinical trials. Additional research must be done to expand the array of treatments available for use as intranasal therapies for neonatal HIE thus improving the neurologic outcomes of infants worldwide.

Exploring client violence during home visits: a qualitative study of perceptions and experiences of Israeli nurses

BACKGROUND

Home care provides an excellent opportunity for personalizing treatment as nurses see patients in their natural environment. Along with its many advantages, the home care environment carries unique risks, as nurses are usually alone, without the protection and security provided by primary care clinics. There are no accurate data in Israel on the scope and characteristics of client violence against nurses during home visits. We conducted a qualitative study to investigate the nature of client violence faced by Israeli nurses during home visits, to gain insights into their perceptions and experiences, and to contribute to the development of effective policies and strategies to combat client violence in the healthcare sector.

METHODS

Twenty-seven female nurses from primary care clinics, who were exposed to client violence during a home visit, were interviewed using a semi-structured interview guide. The interviews were transcribed and analyzed, and categories and themes were extracted.

RESULTS

Most nurses interviewed experienced at least three incidents of client violence, the most common of which was verbal abuse. The nurses perceived that the location of the encounter between the nurse and the patient in the patient's natural surroundings, rather than within the controlled boundaries of a clinic, contributes to the risk of violence. Violence affected the nurses' professional decisions. The nurses reported that their organization had no established guidelines or instructions for safely conducting home visits, they were not provided with protective or security measures for emergencies, nor did they perceive that they had sufficient training to deal with client violence in clients' homes.

CONCLUSIONS

Nurses encounter a range of challenges that make it difficult for them to deal with client violence during home visits, affecting their personal safety and professional decisions. Their ability to manage such situations is shaped by a complex interplay of personal and organizational factors and requires a range of strategies and resources to effectively address them.

Assessment of the effectiveness of hospital external disaster functional drills on health care receivers' performance, using standardized patients and mass cards simulation: a pilot study from Saudi Arabia

BACKGROUND

Given the increasing frequency of disasters globally, it is critical that healthcare systems are prepared for these mass casualty events. The Saudi health system's preparedness for mass casualty incidents needs to be more robust, potentially due to limited disaster drills and inadequate standardized patient (SP) simulation training. This study aims to (i) assess the performance of front-line hospital staff in Saudi Arabia through a functional drill and (ii) evaluate the drill's effectiveness using SP and MAC-SIM cards, providing detailed insights into its design and execution.

METHODS

A functional drill was conducted at a government hospital in Riyadh, Saudi Arabia, on December 19, 2022, using a cross-sectional approach with two phases. 141 healthcare receivers served as subjects, while 23 volunteers acted as SPs. The scenario simulated a building collapse to assess the emergency department (ED) response, interdepartmental communication, and surge capacity. Data were collected through direct observation of healthcare practitioners' interactions with the SPs, analysis of SP data, and participant feedback. Quantitative data were analyzed descriptively, while qualitative data were examined for patterns and themes related to simulation performance and effectiveness.

RESULTS

The hospital receivers' performances demonstrated accurate triage categories. The ED team assessed most patients (67%) in less than 5 min. For patients requiring definitive care, such as intensive care unit, 95% spent less than 2.5 h in the ED. Most patients (65%) required 'other treatments'. Communication was efficient in the triage zone and the yellow treatment area. Participants' feedback on using MAC-SIM cards during the simulation was overwhelmingly positive with 82.61% reporting that MAC-SIM use helped them respond better. Experienced SPs (paramedics) with prior disaster knowledge and experience outperformed inexperienced SPs (nurses) in the functional exercise.

CONCLUSION

This groundbreaking study is the first in the Arabic Gulf region to use SPs with MAC-SIM cards in functional drills. The findings highlight the potential of simulation exercises to improve hospital team knowledge and performance when responding to disasters. Multiple evaluation techniques can effectively identify participant strengths and weaknesses, informing future disaster improvement plans. This information is a valuable resource for Arabic and middle-income countries where disaster medicine is still developing.

The effectiveness of COVID-19 vaccination in preventing hospitalisation and mortality: A nationwide cross-sectional study in Iran

Background

The pandemic of the coronavirus disease 2019 (COVID-19) led to a global health crisis, prompting widespread vaccination efforts to reduce severe outcomes. In this study, we assessed the impact of mass COVID-19 vaccination on hospitalisation and mortality rates in Iran, where over 83% of the vaccinated population received inactivated virus vaccines.

Methods

Using retrospective, cross-sectional analysis, we examined data from the Iran Health Insurance Organisation, covering 41 million individuals from 20 February 2020 to 20 March 2022. We analysed hospital records from 956 Iranian hospitals, focusing on inpatient stays, short-term hospitalisations, and emergency department visits. Study outcomes included COVID-19 hospital admissions and associated mortality. We used negative binomial regression to compare hospital admission rates between periods, while we used a poison regression model with a log link to assess mortality risks before and after vaccination.

Results

Among 806 076 hospital admissions, 57 599 deaths were recorded. COVID-19 hospitalisations increased with age, and women had slightly higher admission rates than men. Advanced age and male sex correlated with higher mortality rates. Hospital admissions rose to 1178.66 per million population per month post-vaccination compared to 459.78 pre-vaccination. The incidence rate ratio was 2.09 (95% confidence interval (CI) = 1.90-2.32, P < 0.001), mainly due to the Delta variant. In contrast, post-vaccination mortality rates decreased from 111.33 to 51.66 per 1000 admissions per month. Post-vaccination, COVID-19 mortality significantly decreased, with a relative risk being 0.61 (95% CI = 0.60-0.62, P < 0.001) across all age groups and sexes.

Conclusions

The Delta variant increased hospital admissions among vaccinated individuals, but widespread vaccination significantly reduced COVID-19-related mortality.

Risk factors for diarrheal diseases among pilgrims during Arba'een mass gathering: a case-control study

BACKGROUND

A significant portion of the Muslim community participates in the Arba'een pilgrimage, with participant numbers increasing each year. There have been relatively few studies on the health of Arba'een Mass gathering (MG). Researching the prevalence and distribution of diseases among Arba'een pilgrims is essential to recognize any outbreaks and take timely responses to contain them. The current study aimed to identify exposures and risk factors for diarrheal disease in pilgrims who referred to the clinics located in Iraq among the Arba'een MG in 2023.

METHODS

This case-control study randomly selected 200 outpatients (100 cases and 100 controls) who were referred to Iraq clinics. Cases were patients with gastrointestinal symptoms (diarrhea), while controls were randomly selected from unaffected pilgrims at the same time for the cases. The study groups matched for age, and sex. Face-to-face interviews using a reliable field based checklist of the Center for Disease Control and Prevention of Iran's Ministry of Health to collect potential exposures and risk factors for diarrheal disease. Multiple logistic regression was used to estimate the crude and adjusted odds ratio (AOR) for the risk of diarrhea with a 95% confidence interval (CI).

RESULTS

The average age of the participants was 38.6 years. Diarrhea in 100% and fever in 81% were the most common clinical symptoms in patients. Having underlying diseases was not associated with an increased risk of diarrhea disease (P > 0.05). Regarding risk factors for diarrheal, the final analysis after adjusting for potential confounders indicated that consumption of insanitary (unpackaged) drinking water (AOR = 1.95; 95% CI: 1.05-3.6; P = 0.024), inappropriate hand washing (AOR = 3.82; 95% CI: 1.7-8.6; P = 0.001), ritual foods (AOR = 2.56; 95% CI: 1.3-5.2; P = 0.004), and public toilets (AOR = 1.46; 95% CI: 1.04-4.3; P = 0.038) were significantly increased the likelihood of diarrheal disease.

CONCLUSIONS

Contamination of water sources, food, inadequate and poor hand washing were the most common sources of diarrheal diseases among Arba'een pilgrims. The results indicate that the potential occurrence of outbreaks, especially water- and foodborne diseases, threatens participants in the Arba'een MG. It is recommended to provide risk assessment, improve pilgrims' awareness, pre-and post-screening, vaccination, compliance with personal hygiene, improvement of the environment, provision of sanitary water and food sources and hygienic disposal of sewage, laboratory diagnosis to identify the common types of pathogens in Arba'een MG.

Latent profile analysis of transdiagnostic emotional distress, suicidality, and resilience in first responders

BACKGROUND

First responders (i.e., law enforcement officers, firefighters, and emergency medical technicians/paramedics), experience significantly higher occupational trauma exposure than U.S. adult workers outside these fields, leading to increased risks of comorbid mental health disorders. Repeated and intense trauma exposure may combine with personal factors to place them at higher risk for suicide. Conversely, first responders may show higher levels of psychological resilience in the face of occupational trauma experiences. Some research exists on resilience, though little is known about suicide resilience in first responder populations.

METHODS

We used latent profile analysis (LPA) on a treatment-seeking sample of first responders (N = 340) with measures of posttraumatic stress disorder (PTSD), generalized anxiety, depression, suicidality, and resilience.

RESULTS

We determined the best fit was a five-class solution, including the following emotional distress categories: minimal (19 %), mild (33 %), moderate (8 %), moderately severe (27 %), and severe (13 %) emotional distress. In this study, all multivariate analyses of variance (MANOVAs) were statistically significant and had large effect sizes ranging from the lowest (resilience) to the largest (depression).

LIMITATIONS

We used self-report assessments and not a clinical interview. Also, we did not have data on measures of substance use, emotional dysregulation (e.g., attachment), or trauma exposure.

CONCLUSIONS

This study underscores the critical need for developing and implementing transdiagnostic interventions that not only address the spectrum of emotional distress and suicidality but also actively enhance resilience among treatment-seeking first responders.

Behind the scenes: a qualitative study on threats and violence in emergency medical services

The increasing prevalence of threats and violence against ambulance clinicians is a critical issue that has not been adequately studied. These incidents pose significant challenges to the provision of prehospital emergency care, affecting both the safety and well-being of the clinicians involved. This study aimed to explore the experiences of Swedish ambulance clinicians when encountering threats and violence during their work. A qualitative approach was used, involving semi-structured interviews with 11 ambulance clinicians from various regions of Sweden. The participants were selected to ensure diversity in gender, age, and educational background. The data were collected over three weeks in 2021 and analyzed using qualitative content analysis. The analysis revealed three key categories related to the challenges faced by ambulance clinicians: Police cooperation challenges, Strategies for a safe care environment, and Impact during and relief after stressful events. These categories highlight the complexities of managing threats and violence in the field. This study sheds light on the multifaceted challenges that ambulance clinicians face due to threats and violence. It underscores the urgent need for comprehensive training, effective communication, and clear role allocation in complex situations. Furthermore, it emphasizes the importance of organized support systems to help clinicians cope with the aftermath of stressful events.

Head and Neck Cancer in Pan-American Notable People: An International Survey

Background: The study of notable people as advocates for raising cancer awareness began in the latter decades of the 20th century. This research aimed to identify Pan-American notable people with head and neck cancer (HNC) and to explore senior health professionals' perspectives on communicating stories of notable patients with HNC to promote prevention. Method: A cross-sectional survey was conducted using an online questionnaire designed in REDCap and administered to 32 senior health professionals with long-standing academic and clinical backgrounds in HNC. In addition, a structured literature review was performed on PubMed, Scopus, EMBASE, Web of Science, LILACS, and gray literature. Results: 18 notable figures were successfully identified from the survey, and 24 from the literature review. These individuals came from the United States, Brazil, Argentina, Mexico, El Salvador, Chile, Colombia, and Peru, and were recognized primarily for their performances as actors, artists, musicians, and athletes. The professionals' outlooks were positive, with 31 (96.9%) agreeing that disseminating these stories can contribute to reducing risk behaviors. Furthermore, all participants (100%) agreed that such stories can promote early detection of HNC, primarily through social media, followed by the internet, and television. Conclusions: The study identified notable individuals and gathered positive perspectives from professionals. Our results suggest that notable people could serve as potential advocates for HNC prevention. Further research is warranted to explore the potential of this prevention strategy.

The Ebola Data Platform: A prospective, standardised, clinical dataset collected during the 2013-2016 West African Ebola outbreak

The Ebola Data Platform (EDP) was developed to strengthen knowledge and capacity across health, research, and humanitarian communities to reduce the impact of Ebola through responsible data use. This collaborative initiative was established by West African governments, NGOs, academic organisations, and intra-governmental health organisations directly involved in the 2013-2016 West African Ebola outbreak. The platform was established to provide a centralised, standardised dataset of individual patient data collected during the outbreak for the purpose of research to improve Ebola treatment and control, and includes over 13,600 patient records of individuals infected and treated from 22 different Ebola treatment centres across Guinea, Sierra Leone, Liberia, and Nigeria. Patient data are available from treatment centre triage and admission, inpatient clinical observations, and outcomes, with outpatient follow-up available for some datasets. Data include signs and symptoms, pre-existing comorbidities, vital signs, laboratory testing, treatments, complications, dates of admission and discharge, mortality, viral strains, and other data. This publication describes characteristics of the EDP dataset, its architecture, methods for data access and tools for utilising the dataset.

Factors affecting the accuracy of prehospital triage application and prehospital scene time in simulated mass casualty incidents

BACKGROUND

The contemporary management of mass casualty incidents (MCIs) relies on the effective application of predetermined, dedicated response plans based on current best evidence. Currently, there is limited evidence regarding the factors influencing the accuracy of first responders (FRs) in applying the START protocol and the associated prehospital times during the response to MCIs. The objective of this study was to investigate factors affecting FRs' accuracy in performing prehospital triage in a series of simulated mass casualty exercises. Secondly, we assessed factors affecting triage-to-scene exit time in the same series of exercises.

METHODS

This retrospective study focused on simulated casualties in a series of simulated MCIs Full Scale Exercises. START triage was the triage method of choice. For each Full-Scale Exercise (FSEx), collected data included exercise and casualty-related information, simulated casualty vital parameters, simulated casualty anatomic lesions, scenario management times, and responder experience.

RESULTS

Among the 1090 casualties included in the primary analysis, 912 (83.6%) were correctly triaged, 137 (12.6%) were overtriaged, and 41 (3.7%) were undertriaged. The multinomial regression model indicated that increasing heart rate (RRR = 1.012, p = 0.008), H-AIS (RRR = 1.532, p < 0.001), and thorax AIS (T-AIS) (RRR = 1.344, p = 0.007), and lower ISS (RRR = 0.957, p = 0.042) were independently associated with overtriage. Undertriage was significantly associated with increasing systolic blood pressure (RRR = 1.013, p = 0.005), AVPU class (RRR = 3.104 per class increase), and A-AIS (RRR = 1.290, p = 0.035). The model investigating the factors associated with triage-to-scene departure time showed that the assigned prehospital triage code red (TR = 0.841, p = 0.002), expert providers (TR = 0.909, p = 0.015), and higher peripheral oxygen saturation (TR = 0.998, p < 0.001) were associated with a reduction in triage-to-scene departure time. Conversely, increasing ISS was associated with a longer triage-to-scene departure time (TR = 1.004, 0.017).

CONCLUSIONS

Understanding the predictors influencing triage and scene management decision-making by healthcare professionals responding to a mass casualty may facilitate the development of tailored training pathways regarding mass casualty triage and scene management.

Analysis on the application of FMEA in 'instrument and equipment surface cleaning and disinfection' in hospitals based on standardization and cleaning and disinfection information system management

Purpose

To analyze the application of 'instrument and equipment surface cleaning and disinfection' in hospitals based on standardization and the management of cleaning and disinfection information systems.

Methods

Employees and all cleaning and disinfected instruments and equipment from 56 inpatient departments in our hospital were selected as the subjects of observation. The period before the intervention (January 2023) was designated as the control group, while the period after the intervention (July 2023) was designated as the study group. In the control group, the instruments and equipment under routine management were disinfected. The research team applied the Failure Mode and Effects Analysis (FMEA) method to clean and disinfect the surfaces of instruments and equipment on the basis of standardization and cleaning and disinfection information system management. Employees' theoretical knowledge points and operational skill scores before and after the intervention were compared and evaluated. The changes in the risk priority coefficient (RPN) values of high-risk factors were analyzed. Fifty-six clinical medical staff from 56 inpatient departments in the hospital were selected to evaluate the clinical satisfaction of the cleaning and disinfection management of instruments and equipment before and after the intervention, and the clinical satisfaction of the two groups was compared.

Results

The scores of theoretical knowledge and operational skills of the staff in the research group were significantly higher than those in the control group. The passing rates of theoretical knowledge and operational skills in the control group and the research group were 44.64 and 94.64% respectively, and 55.36 and 96.43%, respectively. The qualified rate of theoretical knowledge and operational skills of staff in the study group was significantly higher than that in the control group (p < 0.05). The RPN scores of medical personnel, environment, system and system guarantee factors in the control group were 80, 80, 80, and 100, respectively. The RPN scores of medical personnel factors, environmental factors, system factors and system guarantee factors in the research group were 6, 24, 24, and 36, respectively.

Conclusion

Through standardization and cleaning and disinfection information system management, the theoretical knowledge and technical operation capabilities of cleaning can be effectively improved.

Feasibility of ultrasound-guided nerve blocks in simulated microgravity: a proof-of-concept study for regional anaesthesia during deep space missions

BACKGROUND

With crewed deep space exploration on the horizon, preparation for potential astronaut health crises in space missions has become vital. Administration of anaesthesia and analgesia presents many challenges owing to constraints specific to space (physiologic and ergonomic challenges associated with microgravity) and nonspecific factors (isolation and lack of supplies). Regional anaesthesia can be the safest option; however, we hypothesised that the ergonomics of microgravity would compromise ease and accuracy of nerve blocks.

METHODS

We evaluated the feasibility of regional anaesthesia in a simulated microgravity environment (free-floating underwater conditions) using a meat (bovine muscle) model. Forty meat models were randomised for injection under simulated microgravity or normal gravity conditions. Success rates were determined by blinded assessors after injection. Parameters assessed included time to block, ease of image acquisition, and ease of needle placement.

RESULTS

The median time to block in normal gravity was 27 (interquartile range 21-69) s vs 35 (interquartile range 22-48) s in simulated microgravity (P=0.751). Ease of image acquisition was similar in both conditions, as was ease of needle placement. There was no significant difference in the rate of accidental intraneural injections (5% vs 5%), with block success rates comparable in both scenarios (80% normal gravity vs 85% microgravity, P>0.999).

CONCLUSIONS

Regional anaesthesia appears feasible for experts in simulated microgravity despite the ergonomic challenges. Although our model has limitations and might not fully capture the complexities of actual space conditions, it provides a foundation for future research into anaesthesia and analgesia during deep space missions.

Investigation of Psychometric Properties and Correlation with Psychological Distress after Hurricane Hazards in Puerto Rico

BACKGROUND

Puerto Rico (PR) is highly vulnerable to hurricanes, which severely impact cancer survivors by causing healthcare disruptions and increasing stress. This study investigates the reliability and factor structure of the Hurricane Hazards Inventory (HHI) and its relationship with psychological distress among cancer survivors and non-cancer controls in PR.

METHODS

Using secondary data from a longitudinal study following Hurricane Maria (HM), the baseline assessment included sociodemographic data from participants, HHI, Patient Health Questionnaire (PHQ-8), and Generalized Anxiety Disorder (GAD-7). Statistical analyses involved descriptive statistics, Exploratory Factor Analysis (EFA), and Partial Least Squares Structural Equation Modeling (PLS-SEM).

RESULTS

Among 260 participants, 78.7% were women, with a median age of 58.0 years. EFA reduced the HHI to 17 items grouped into three factors explaining 62.6% of the variance with excellent reliability (Cronbach's alpha 0.91). The three factors also showed good to excellent reliability (alpha 0.81 to 0.92). The median HHI score was 11.0 (range 4.0-26.5) out of 68. PLS-SEM revealed a direct effect of being a cancer survivor and tertiary hazards on depression and anxiety.

CONCLUSION

The HHI is a valid and reliable tool for assessing mental health impact in cancer survivors after hurricanes. However, the study had limitations, including its small sample size and lack of control for all confounding variables. Future research with larger and more diverse samples is needed to further validate the HHI and examine its generalizability.

Critical Steps for Determining Capacity to Refuse Emergency Medical Services Transport: A Modified Delphi Study

OBJECTIVES

Emergency physicians without specialized Emergency Medical Services (EMS) training are often required to provide online medical oversight. One common ethical question faced by these physicians is the assessment for decision-making capacity in a patient who does not accept EMS transport to the hospital. We sought expert consensus for a standardized set of guiding questions and recommendations to ensure a rigorous and feasible capacity assessment.

METHODS

A modified Delphi method approach was used to achieve group consensus among expert individuals. Nineteen physician experts were recruited from across the country, representing populations totaling over 22 million and a variety of urban, suburban, and rural practice environments. Experts completed a Round 1 survey that included 19 questions surrounding best practices for capacity evaluation among patients refusing transport. The threshold for consensus was predefined as 80% agreement. Participants gathered virtually meeting where the results from the first round were shared with the group. Discussion generated new items and refined the language of existing items. Following the virtual meeting, a Round 2 survey was conducted, and voted on by the panel for the items that did not meet consensus in Round 1.

RESULTS

After the first round, 15 of 19 items reached consensus. Three of the items that met consensus were universally noted to require language modification for clarification. A large portion of the discussion involved the proper method of integrating patient concerns around ambulance transport (e.g., cost of transport, financial concerns, social barriers) into the capacity assessment and whether alternate care options should be discussed. After the second round of voting, one additional item was reversed to meet consensus, resulting in a total of 16 items.

CONCLUSIONS

A consensus expert panel was able to agree upon 16 standardized steps to guide best practices and assist emergency physicians in real-time evaluation of patients that refuse EMS transport.

A structural equation model of parenting and child's resilience after the earthquake in Türkiye

This study investigated the relationship between parental psychological wellbeing, parenting, children's psychological difficulties, and prosocial behavior in Kahramanmaraş earthquake-affected families living in Türkiye in 2023. To this end, a mediation model was proposed for parental psychological distress that was hypothesized to exert an indirect effect on a child's psychological difficulties and prosocial behavior through parenting. Participants were 358 preschoolers between 4 and 6 years old and their one parent (father or mother) who completed a set of validated self-report surveys in a cross-sectional design study. Results showed positive associations between parental psychological distress and child's psychological difficulties but negative association with child's prosocial behavior. Furthermore, quality of parenting mediated the association between parental psychological distress and child's psychological difficulties and prosocial behavior. Our findings suggest that positive parenting may serve as a protective mechanism that mediates the association between parental psychological distress and a child's psychological difficulties and prosocial behaviors among families displaced by a natural disaster like an earthquake. These findings point to the need for supporting positive parent-child relationships in addition to decreasing the psychological distress of parents when exposed to potentially traumatizing events like this.

Valued technical and non-technical skills among disaster responders: a cross sectional study of disaster responders involved in the earthquake in Türkiye and Syria January 2023

INTRODUCTION

Disaster responders are an important part of disaster response. However, despite large efforts to train disaster responders, there is a limited scientific knowledge regarding which competences and skills such responders value and lack during a real mission. The aim of this study was to investigate used and needed skills among disaster responders responding to the earthquake in Türkiye and Syria 2023 METHODS: A cross-sectional study using a non-randomized sample was conducted, collected between March and July, 2023. The participants were recruited through invitations distributed to international organizations, and the data were gathered through a web-based survey. The data were analyzed using descriptive and comparative statistics.

RESULTS

A total of 525 participants involved in the disaster response in Türkiye or Syria in February 2023 were included. The most common valued skills were teamwork skills (n = 252, 59%), technical knowledge (n = 204, 48%), leadership skills (n = 105, 24%) and communication skills (n = 114, 17%). Women valued stress management (n = 33, 26%) more than leadership (n = 24, 19%) Technical knowledges were more valued among first-time responders (n = 168, 82%) compared to experienced responders (n = 108, 54%, p-value < 0.001). The most reported lacked skills were mental preparedness (n = 237, 53%), knowledge of the management system of international response (n = 132, 30%), stress management (n = 105, 24%) and leadership (n = 102, 23%).

CONCLUSION

The results showed slightly different needs in the various phases of a response, as well as some differences between men and women. Improving mental preparedness was not one of the most highly valued skills, but it was one of the skills that was most lacking; this discrepancy is an interesting finding. More in-depth analysis and additional studies are needed to further understand how best to prepare disaster responders and how their training can include the desirable skills. Further studies should be focused on the experience and knowledge of qualified disaster responders. This knowledge could also be of use when recruiting since several of the non-technical skills are not only gained solely through specific training.

Tanzanian midwives' clinical practices and experiences in caring for women with antepartum hemorrhage: a critical incident technique study

BACKGROUND

Antepartum hemorrhage (APH) is an obstetric emergency that complicates pregnancy worldwide and continues to lead to hemorrhagic conditions in parts of Tanzania. Midwifery education received by midwives consists theoretical knowledge on the subject but with no or minimal practical skills in the laboratory, which may reduce their practical capacity as graduated midwives. This study therefore aimed to explore midwives' clinical actions and experiences regarding the care of women with APH in Mwanza region.

METHOD

Qualitative, inductive approach with critical incident technique was used. Data were analysed using the critical incident technique, and a question guide consisting of eleven open-ended questions was used to collect data from 44 out of 60 midwives who graduated not less than one year. A total of 522 critical incidents, with 199 actions and 323 experiences, were identified and categorized into five main areas. Ethical approval was obtained.

RESULTS

Midwives' clinical actions and experiences in caring for women with APH are affected by the knowledge and skills obtained during training at school. They have insufficient theoretical knowledge and practical skills, leading to inadequate identification of the problem and the implementation of care. A need for additional preventive care is described and structural issues, such as co-operation, referral to other instances, access to equipment and relevant treatments need to be improved.

CONCLUSION

The actions taken to provide care for women with APH were related to their ability to identify problems, implement care and carry out structural initiatives. However, the midwives' experience was influenced by an attempt to understand the seriousness of the situation and the existence of an organizational challenge. The results can provide knowledge and tools to improve midwives' education and clinical practice and in the long run, prevent complications, improves health and minimize suffering in women with APH.

Cardiovascular events in crush syndrome: on-site therapeutic strategies and pharmacological investigations

Crush syndrome often occurs after severe crush injury caused by disasters or accidents, and is associated with high mortality and poor prognosis. Cardiovascular complications, such as cardiac arrest, hypovolemic shock, and hyperkalemia-related cardiac dysfunction, are the primary causes of on-site death in crush syndrome. Prehospital evaluation, together with timely and correct treatment, is of great benefit to crush syndrome patients, which is difficult in most cases due to limited conditions. Based on current data and studies, early fluid resuscitation remains the most important on-site treatment for crush syndrome. Novel solutions and drugs used in fluid resuscitation have been investigated for their effectiveness and benefits. Several drugs have proven effective for the prevention or treatment of cardiovascular complications in crush syndrome, such as hypovolemic shock, hyperkalemia-induced cardiac complications, myocardial ischemia/reperfusion injury, ventricular dysfunction, and coagulation disorder experimentally. Moreover, these drugs are beneficial for other complications of crush syndrome, such as renal dysfunction. In this review, we will summarize the existing on-site treatments for crush syndrome and discuss the potential pharmacological interventions for cardiovascular complications to provide clues for clinical therapy of crush syndrome.

The effect of clinical supervision model on nurses' self-efficacy and communication skills in the handover process of medical and surgical wards: an experimental study

BACKGROUND

The handover process is a vital part of patient safety continuity, particularly conducted between nurses at the end of shifts. Nurses often face challenges in handover due to a lack of self-efficacy and inadequate communication skills. The clinical supervision model, by providing emotional, educational, and organizational support, aids in skill acquisition and instills confidence.

OBJECTIVE

This study was conducted to investigate the effect of the clinical supervision model on nurses' self-efficacy and communication skills in the handover process within medical and surgical wards.

METHOD

This experimental two-group (pre-and post-test) study was conducted in 2024 at selected hospital affiliated with Isfahan University of Medical Sciences, Isfahan, Iran. Convenience sampling was used, and participants were randomly assigned to either the intervention or control group. Data were collected using the ISBAR communication checklist, communication clarity, the Sherer General Self-Efficacy Scale (GSES), the Visual Analog Scale (VAS) for handover self-efficacy, and the Manchester Clinical Supervision Scale (MCSS). The clinical supervision model and routine supervision were implemented in six sessions for the intervention and control groups, respectively. Data were analyzed using SPSS version 16, employing independent t-tests, covariance analysis, paired t-tests, chi-square tests, and repeated measures ANOVA with a significance level of p < 0.05.

RESULTS

No significant differences were observed between the intervention and control groups in terms of baseline characteristics. Inter-group analysis indicated that there were no significant differences in the scores of self-efficacy, ISBAR, and communication clarity between the control and intervention groups before the intervention (P > 0.05). According to the intra-group analysis, the ISBAR and communication clarity scores in the intervention group significantly increased over time (p < 0.001), whereas no such increase was observed in the control group. The intervention group showed a significant increase in general self-efficacy (p < 0.001) compared to the control group. Although both groups showed a significant improvement in handover self-efficacy, the mean scores of the intervention group were higher than those of the control group (p < 0.001). The mean score of the Manchester Clinical Supervision Scale in the intervention group was 128.98, indicating the high effectiveness of implementing the clinical supervision model.

CONCLUSION

The findings indicated that the use of the clinical supervision model improves self-efficacy and communication skills in the handover process of nurses in medical and surgical wards. Therefore, it is recommended to use this model in handover training to enhance the quality of care and improve patient safety.

Evaluation of a collaborative multi-disciplinary train-the-trainer program for first responders in chemical, radiologic and nuclear emergencies - a pre- and post-test

BACKGROUND

In significant events like chemical, biological, radiological, nuclear, and explosive (CBRNE) incidents, additional expertise in specific chemical substances becomes essential. Train-the-trainer programmes are used to increase knowledge and skills in a variety of fields and have been shown to be a cost-effective training method, eliminating the necessity of bringing in external experts or requiring participants to travel outside their region. Care in Hazardous Environments (CiHE) is one example of a course which comprises basic multi-disciplinary training together with personnel from rescue, police, and emergency medical services to prepare them to handle chemical and radioactive nuclear incidents. The train-the-trainer programme described in this study contains both theoretical and practical components, intended for instructors who will lead training on CiHE incidents. This study aimed to evaluate trainers' level of knowledge before and after a train-the-trainer programme, as well as their thoughts about becoming an instructor i.e. the pedagogical competence for the Care in Hazardous Environments course.

METHODS

A pre- and post-test, along with an evaluation of open-ended response options were employed to assess the effectiveness of the train-the-trainer programme for teaching the basic course (CiHE). A total of 49 participants were enrolled in the programme.

RESULTS

Participants showed significant improvement in chemical, radiological and nuclear (CRN) response knowledge in two of the eight questions between the pre- and post-tests. The two questions that improved pertained to chemical substances and basic principles of radiation protection. Instructors trained in the train-the-trainer programme are intended to bring new knowledge, incorporate a rarely discussed topic into instruction regularly, and de-stigmatise CRN incidents by helping raise the minimum competency levels in their respective organisation.

CONCLUSION

An effective response to CBRNE events begins with readiness. First responders must be prepared and possess knowledge of both CRN components as well as protective gear to keep themselves and others safe at the incident scene. This study shows the importance of the train-the-trainer programme in continuing to educate police, and personnel from rescue and emergency medical services in CiHE, enable them to collaboratively prepare to handle CRN incidents.

Mobile Critical Care in Resource-Limited Settings: An Unmet Need

Care of the critically ill in resource-limited areas, inside or outside the intensive care unit (ICU), is indispensable. Murthy and Adhikari noted that about 70% of patients in low-middle income (LMIC) areas could benefit from good critical care. Many patients in resource-limited settings still die before getting to the hospital. Investing in capacity building by strengthening and expanding ICU capability and training intensivists, critical care nurses, respiratory therapists, and other ICU staff is essential, but this process will take years. Also, having advanced healthcare facilities that are still far from remote areas will not do much to alleviate distance and mode of transportation as barriers to achieving good critical care. This paper discusses the importance of mobile critical care units (MCCUs) in supporting and enhancing existing emergency medical systems. MCCUs will be crucial in addressing critical delays in transportation and time to receive appropriate lifesaving critical care in remote areas. They are incredibly versatile and could be used to transfer severely ill patients to a higher level of care from the field, safely transfer critically ill patients between hospitals, and, sometimes, almost more importantly, provide standalone short-term critical care in regions where ICUs might be absent or immediately inaccessible. MCCUs should not be used as a substitute for primary care or to bypass readily available services at local healthcare centers. It is essential to rethink the traditional paradigm of 'prehospital care' and 'hospital care' and focus on improving the care of critically ill patients from the field to the hospital.

The effects of incivility on student nurses in the clinical setting: A grounded theory approach

AIM

To use a grounded theory approach to explore and understand the encounters of undergraduate nursing students with incivility in the clinical setting so that data-informed strategies for addressing this counterproductive behavior could be developed.

BACKGROUND

Nurses are being called upon to fill ever-increasing responsibilities associated with expanding roles in different specialties within healthcare. One issue that has developed in this high-pressure environment is an increase in incivility in the workplace that spills over into the clinical training environment. As a pervasive problem in the healthcare system, its effects on nursing students could compound the nursing shortage by undermining the integrity of nursing education and discouraging individuals from entering the profession. Therefore, it is vital to construct new theories regarding incivility so that this unprofessional practice can be eradicated or reduced. When this is done, there may be a renewed hope for new nursing students to practice their clinical rotations without feeling disrespected, undermined and intimidated. Students should be able to complete clinical rotations without these unnecessary barriers.

DESIGN

Qualitative grounded theory using philosophical underpinnings of symbolic interactionism and pragmatism.

METHODS

A classical grounded theory approach focusing on the Glaserian Model was used to develop an inductively derived theory from the data. Participants were interviewed about their encounters with incivility and then open coding was used to identify recurring concerns on which a model of the effect of these occurrences could be established. The study sample consisted of 32 participants of which 25 were undergraduate nursing students and seven were graduate students who participated in a focus group. Data were collected through face-to-face (in-person and virtual) structured interviews that were audiotaped. These individuals were recruited by flyers posted at varying strategic points on university campuses.

RESULTS

Open coding of student responses revealed three significant areas of concern: feelings of being disrespected, intimidated and undermined, from which the Inhibiting Actions Theory emerged.

CONCLUSION

Nursing students' perceptions of incivility and their attitudes and behaviors toward this occurrence culminated in the Inhibiting Actions Theory, which provides a framework for implementing effective policies and personnel training in clinical settings. The hope is that these research findings will be a call to action for introducing systemic changes in the clinical training environment, thereby improving the clinical experiences of nursing students and patients.

Elder Mistreatment Documentation by Prehospital Clinicians: An Analysis of the National Emergency Medical Services Information System Database

OBJECTIVES

Elder mistreatment (EM), encompassing abuse and neglect, is a significant public health issue, affecting up to 10% of community-dwelling older adults annually. Elder mistreatment is a growing concern with a higher prevalence in institutional settings and substantial associated healthcare costs. Prehospital clinicians (PHCs) such as emergency medical technicians and paramedics are uniquely positioned to detect and report EM during their interactions with older adults in their homes. The objective of the study is to describe the rate and characteristics of EM documented by PHCs using the National Emergency Medical Services Information System (NEMSIS) database.

METHODS

This study analyzed data from NEMSIS, which includes standardized information about PHC emergency response encounters across the United States. In 2018, 22,532,890 activations were included from 9,599 agencies in 43 states and US territories. Elder mistreatment was identified using specific International Classification of Diseases (ICD) codes related to EM. Demographic data, injury location, and associated physical findings were also examined.

RESULTS

Out of 9,605,522 EMS encounters for patients aged ≥60, EM was coded in 1,765 encounters (0.02%). Most EM cases were listed as the cause of injury (64%), followed by the clinician's first impression (25.4%). Physical abuse was the most common type of mistreatment reported (20.8%), followed by sexual abuse (18.2%), neglect (9.7%), and psychological/emotional abuse (0.34%). The median age of patients with documented EM was 72, and 62.3% were female. The most common anatomic locations of injuries were the lower extremities, head, and upper extremities.

CONCLUSIONS

Despite the high prevalence of EM, PHCs infrequently document EM in their encounters with older adults. Additional training and comprehensive protocols are needed to improve the identification and reporting of EM, mainly elder neglect. Empowering PHCs through education and protocol development can significantly impact the detection and intervention of EM.

Incidence, severity and changes of abnormal vital signs in trauma patients: A national population-based analysis

BACKGROUND

Physiological criteria are used to assess the potential severity of injury in the early phase of a trauma patient's care trajectory. Few studies have described the extent of abnormality in vital signs and different combinations of these at a national level. Aim of the study was to identify physiologic abnormalities in trauma patients and describe different combinations of abnormalities and changes between the pre-hospital and emergency department (ED) settings.

METHOD

Norwegian Trauma Registry (NTR) data between 01.01.15 - 31.12.18, where evaluated on the prevalence and characteristics of abnormal physiologic variables. Primary outcome were rates of hypoventilation (respiratory rate [RR] < 10 breaths per min), hyperventilation (RR > 29 breaths per min), hypotension (systolic blood pressure [SBP] < 90 mmHg), and reduced level of consciousness (Glasgow Coma Scale [GCS] < 13).

RESULTS

A total of 24,482 patients were included. Documented values for RR, SBP and GCS were 77.6%, 78.5% and 81.9% in the pre-hospital phase, and the corresponding percentages in the ED were 95.5%, 99.2% and 98.6%, respectively. In the pre-hospital phase, 3,615 (14.8%) patients had at least one abnormal vital sign, whereas the corresponding numbers in the ED, were 3,616 (14.8%) patients. The most frequent combination was low GCS and hyperventilation. A worsened RTS-score from pre-hospital phase to the ED was observed for RR, SBP and GCS in 3.9%, 1.2% and 1.9% of incidents, respectively. Overall 30-day mortality was 3.1% (n=752). Of these, 60.8% had abnormal vital signs, with decreased GCS as the most prevalent (61.3%).

CONCLUSION

Most trauma patients had normal vital signs. According to the RTS-score, there were few deteriorations in RR, SBP and GCS between pre-hospital phase and the ED. The most frequent abnormality was low GCS, with a higher proportion in those who died within 30 days.

The Perceived Weight Stigma Scale and Weight Self-Stigma Questionnaire: Rasch analysis, confirmatory factor analysis, and network analysis among Chinese adolescents

OBJECTIVES

The objectives of the present study were to (i) re-evaluate and expand the psychometric properties of two weight stigma instruments-the Perceived Weight Stigma Scale (PWSS) and the Weight Self-Stigma Questionnaire (WSSQ) among a large sample of adolescents using advanced psychometric methods and (ii) examine how the different types of weight stigma (i.e., PWSS and WSSQ) are associated with psychological distress.

STUDY DESIGN

Cross-sectional study.

METHODS

In September 2023, a cross-sectional survey utilising convenience sampling was used to recruit 9995 adolescents (mean age = 16.36 years [standard deviation = 0.78]; 57.8% males). They completed the PWSS, WSSQ, and a measure on psychological distress. The data were analysed using Rasch analysis, confirmatory factor analysis (CFA), structural equation modelling (SEM), and network analysis.

RESULTS

The CFA and Rasch model results showed acceptable psychometric properties regarding factor structure, factor loading, difficulty, and infit and outfit mean squares (except Items 4 and 7 of the PWSS). There was no substantial differential item functioning for any tested items across the sex and weight categories. The CFA and SEM results showed promising validity indices with significant associations between both weight stigma scales and psychological distress (i.e., depression, anxiety, and stress). Network analysis showed inter-variable connectivity between nodes PWSS3 ("People act as if they are afraid of you") and WSSQF7 ("I feel insecure about others' opinions of me").

CONCLUSIONS

Both weight stigma scales had acceptable psychometric properties and were significantly associated with psychological distress, although each assessed different types of weight stigma. This suggests that researchers and clinicians can use these scales to reliably and validly assess weight stigmas among adolescents.

The Impact of "Soft" and "Hard" Flood Adaptation Measures on Affected Population's Mental Health: A Mixed Method Scoping Review

BACKGROUND

The frequency and severity of floods has increased in different regions of the world due to climate change. It is important to examine how adaptation measures impact the mental health of individuals affected by these disasters.

OBJECTIVE

The goal of this scoping review was to document the existing studies on the impact of flood adaptation measures in affected populations to identify the best preventive strategies and limitations that deserve further exploration.

METHODS

This study followed the PRISMA-ScR guidelines. Inclusion criteria focused on studies in English or French available in MEDLINE and Web of Science that examined the impact of adaptation measures on the mental health of flood victims. Literature reviews or non-study records were excluded from the analysis.

RESULTS

A total of 857 records were obtained from the examined databases. After 2 rounds of screening, 9 studies were included for full-text analysis. Six studies sought to identify the factors that drive resilience in flood victims, whereas 3 studies analyzed the impact of external interventions on their mental health.

CONCLUSIONS

The limited number of studies demonstrates the need for public health policies to develop flood adaptation measures that can be used to support the mental health of flood victims.

Derivation of a clinical decision rule for termination of resuscitation in non-traumatic pediatric out-of-hospital cardiac arrest

AIM

Prehospital termination of resuscitation (ToR) rules are used to predict medical futility in adult out-of-hospital cardiac arrest (OHCA), however, the available evidence for pediatric patients is limited. The primary aim of this study is to derive a Pediatric Termination of Resuscitation (PToR) prediction rule for use in pediatric non-traumatic OHCA patients.

METHODS

We analyzed a retrospective cohort of pediatric OHCA patients within the CARES database over a 10-year period (2013-2022). We split the dataset into training and test datasets and fit logistic regressions with Least Absolute Shrinkage and Selection Operator (LASSO) to select predictor variables and estimate predictive test characteristics for the primary outcome of death and a secondary composite outcome of death or survival to hospital discharge with unfavorable neurologic status.

RESULTS

We analyzed a sample of 21,240 children where 2,326 (11.0%) survived to hospital discharge, and 1,894 (8.9%) survived to hospital discharge with favorable neurologic status. We derived a PToR rule for death demonstrating a specificity of 99.1% and a positive predictive value (PPV) of 99.8% and a PToR rule for death or survival with poor neurologic status with a specificity of 99.7% and PPV of 99.9% within the test dataset.

CONCLUSION

We derived a clinical prediction rule with high specificity and positive predictive value in prehospital settings utilizing Advanced Life Support (ALS) providers which may inform termination of resuscitation considerations in pediatric patients. Further prospective and validation studies will be necessary to define the appropriateness and applicability of these PToR criteria for routine use.

Treatment-related Problems and Countermeasures for Patients Undergoing Maintenance Hemodialysis Following Tropical Cyclones: A Scoping Review

BACKGROUND

Patients undergoing maintenance hemodialysis face heightened vulnerability during disasters like tropical cyclones, yet there is sparse research on their treatment-related challenges and countermeasures. This scoping review aims to highlight the issues maintenance hemodialysis patients encounter following tropical cyclones.

METHODS

A systematic scoping review of 19 articles from 2000 to 2023 was conducted, evaluating eligibility against predefined criteria.

RESULTS

Hemodialysis patients encounter substantial challenges during and after tropical cyclones in the United States, Puerto Rico, Australia, and Taiwan. Thematic analysis identified 3 themes related to "challenges" (Hemodialysis health-related challenges, socially relevant challenges, and challenges of management inefficiencies). "Recommendations" comprised 4 themes and 4 phases across the "mitigation phase" (fortifying healthcare infrastructure and mobilizing community-focused risk mitigation initiatives), "preparedness" (emergency plan development, training, and patient education), "response" (activation of emergency plans and providing emergency healthcare services), and "recovery" (intersectoral collaboration for recovery and rebuilding).

CONCLUSION

This scoping review underscores challenges confronted by patients undergoing maintenance hemodialysis post-tropical cyclones, highlighting the urgent need for targeted strategies to ensure the continuity of dialysis care during and after such disasters.

Global Sex Disparities in Bystander Cardiopulmonary Resuscitation After Out-of-Hospital Cardiac Arrest: A Scoping Review

This scoping review collates evidence for sex biases in the receipt of bystander cardiopulmonary resuscitation (BCPR) among patients with out-of-hospital cardiac arrest patients globally. The MEDLINE, PsycINFO, CENTRAL, and Embase databases were screened for relevant literature, dated from inception to March 9, 2022. Studies evaluating the association between BCPR and sex/gender in patients with out-of-hospital cardiac arrest, except for pediatric populations and cardiac arrest cases with traumatic cause, were included. The review included 80 articles on BCPR in men and women globally; 58 of these studies evaluated sex differences in BCPR outcomes. Fifty-nine percent of the relevant studies (34/58) indicated that women are less likely recipients of BCPR, 36% (21/58) observed no significant sex differences, and 5% (3/58) reported that women are more likely to receive BCPR. In other studies, women were found to be less likely to receive BCPR in public but equally or more likely to receive BCPR in residential settings. The general reluctance to perform BCPR on women in the Western countries was attributed to perceived frailty of women, chest exposure, pregnancy, gender stereotypes, oversexualization of women's bodies, and belief that women are unlikely to experience a cardiac arrest. Most studies worldwide indicated that women were less likely to receive BCPR than men. Further research from non-Western countries is needed to understand the impact of cultural and socioeconomic settings on such biases and design customized interventions accordingly.

Methods of Using a Manual Defibrillator during Simultaneous Cardiac Arrest in Two Patients-Analysis of the Actions of Emergency Medical Response Teams during the Championships in Emergency Medicine

Background/Objectives: Conducting advanced resuscitation requires medical personnel to carry out appropriately coordinated actions. Certain difficulties arise when it becomes necessary to conduct cardiopulmonary resuscitation (CPR) on two patients at the same time. The aim of this paper was to assess the actions of teams participating in emergency medicine championships in tasks related to simultaneous cardiac arrests in two patients. Methods: The study was conducted on the basis of an analysis of assessment cards for tasks carried out during the 'International Winter Championships in Emergency Medicine'. Three-person medical response teams (MRTs), with the support of two people, had the task of conducting advanced resuscitation on an adult and child simultaneously. The tasks were prepared and developed by European Resuscitation Council (ERC) instructors. Results: The study showed that teams used four methods of checking heart rhythm and performing defibrillation during CPR-using paddles only, using paddles and self-adhesive electrodes, using paddles and a three-lead ECG and using two pairs of self-adhesive electrodes. Teams performing cardiopulmonary resuscitation using paddles and a three-lead ECG performed significantly more actions incorrectly than other teams-in part due to the fact that they incorrectly interpreted which patient's heart rhythm was displayed on the defibrillator screen. The effectiveness of the remaining methods was similar for most of the actions. The CPR method using two pairs of electrodes enabled personal safety to be maintained to the significantly highest percentage during defibrillation. Conclusions: The study demonstrated that the need to conduct CPR on two patients at the same time, irrespective of the method used, caused MRT members considerable difficulties in correctly conducting some of the actions. The method of assessing heart rhythm using paddles and a three-lead ECG should not be used. The study showed that the optimal method of CPR in use appears to be the method using two pairs of adhesive electrodes-it provided, among other things, the significantly highest percentage of safely conducted defibrillation.

Possibility of the optimum monitoring and evaluation (M&E) production frontier for risk-informed health governance in disaster-prone districts of West Bengal, India

An efficient M&E system in public healthcare is crucial for achieving universal health coverage in low- and middle-income countries, especially when the need for service remains unmet due to the exposure of the population to disaster risks and uncertainties. Current research has conducted exploratory and predictive analyses to estimate the determinants of sustainable M&E solutions for ensuring uninterrupted access during and after disasters. The aim was to estimate the efficiency of reaching a higher M&E production frontier via the Cobb‒Douglas model and stochastic frontier model as the basic theoretical and empirical frameworks. The research followed a deductive approach and used a stratified purposive sampling method to collect data from different layers of health and disaster governance in a flood-prone rural setting in the Malda, South 24 Parganas and Purulia districts in West Bengal, India. The present mixed-method study revealed multiple challenges in healthcare seeking during disasters and how a well-structured M&E system can increase system readiness to combat these challenges. The stochastic frontier model estimated the highest M&E frontier producing the most attainable M&E effectiveness through horizontal convergence between departments, enhanced coordination, the availability of frontline health workers at health centers, the adoption of learned innovation and the outsourcing of the evaluation component to external evaluators to improve M&E process quality. Although the study has several limitations, it shows the potential to increase technical and allocative efficiency through building skills in innovative techniques and applying them in process implementation. In the future, research on strategy improvement followed by real-world evidence-based policy advocacy is needed to increase the impact of M&E on access to healthcare services.

Use of Emergency Mental Health Dispatch Training by a 9-1-1 Medical Dispatcher Assisting a Caller Expressing Suicidal Intent: A Case Report

A growing number of individuals with unmet mental health needs in the United States rely on emergency medical services during mental health crises, and 9-1-1 emergency medical dispatchers (EMD) are often a critical lifeline to help. Unfortunately, current industry-standard dispatching protocols and training required for EMD certification largely lack specificity for managing 9-1-1 calls related to mental health emergencies. The purpose of this report is to illustrate the value of additional targeted training for EMDs that enables them to more effectively assist callers struggling with mental illness or suicidal thoughts. We review a 9-1-1 call in which an EMD utilized specific strategies and language learned during a 3-day emergency mental health dispatch (EMHD) training course to assist a middle-aged male who was expressing suicidal intent with a firearm. Key principles and phrasing from the training were used successfully by the EMD to dissuade the caller from self-harm, and he was ultimately safely met by first responders on scene and transported for care. We also share post-call recollections and reactions from the EMD to demonstrate how in addition to reducing risks for callers and their families, EMHD training has the potential to reduce on-scene risks for field responders and may increase confidence and mitigate negative stress responses in EMDs. Emergency medical services systems in the United States should continue to explore enhanced training and protocols to improve care for 9-1-1 callers experiencing mental health crises.

Police Involvement in Out-of-Hospital Cardiac Arrest: A Qualitative Exploration of Law Enforcement Roles and Contributing Organizational Factors

OBJECTIVES

Many American police organizations respond to out-of-hospital cardiac arrest (OHCA). This study sought to: 1) explore variation in the role of police in OHCA across emergency medical systems and 2) identify factors influencing this variation.

METHODS

We conducted a qualitative multisite case study analysis using data collected through semi-structured key informant interviews and multidisciplinary focus groups with telecommunicators, fire, police, emergency medical services, and hospital personnel across nine Michigan emergency systems of care. Sites were sampled based on return of spontaneous circulation rates, trauma region, geography, rurality, and population density. Data were analyzed to examine police role in OHCA and the organizational factors that contribute to these roles. Transcripts and coded data were explored using iterative thematic analysis and matrices.

RESULTS

Interviews included approximately 160 public safety informants of varying administrative levels (i.e., field staff, mid-level managers, and leadership). Across systems, police played four on-scene roles in OHCA response: 1) early responder, 2) resuscitation team member, 3) security, and 4) information gathering. Less consistently, police performed supplementary roles as telecommunicators and cardiac arrest educators. We found that factors including administrative structure of the police agency, resources (e.g., human and material), organizational culture, medical training, deployment and response policies, nature of response environment, and relationships with other prehospital stakeholders contributed to the degree certain roles were present.

CONCLUSIONS

Police serve numerous on-scene and supplementary roles in OHCA response across jurisdictions. Their roles were influenced by multiple factors at each site. Future studies may help to better understand the value of and how to optimize police engagement in OHCA response.
