Violent encounters on the front line: Sequential explanatory mixed-methods investigation of physical violence factors in the prehospital setting.

OBJECTIVE: Workplace violence (WPV) is an important issue in prehospital care, especially for emergency medical technicians ( EMTs) who are at increased risk of physical violence due to the nature of their work. This study aimed to shed light on the specific factors that contribute to the underlying causes of physical WPV in the prehospital context through direct experience and insight into the work of EMTs. METHODS: Sequential explanatory mixed methods were applied in five western provinces of Iran from 2022 to 2023. In total, 358 EMTs that met the criteria for the quantitative phase were selected using a multi-stage clustering method. In the quantitative phase, the researchers used a questionnaire on workplace violence in the healthcare sector. Based on the results of the quantitative phase, 21 technicians who had experienced physical violence in the past 12 months were invited for in-depth interviews in the qualitative phase. RESULTS: The average age of the EMTs was 33.96 ± 6.86 years, with an average work experience of 10.57 ± 6.80 years. More than half (53.6%) of the staff worked 24-hour shifts. In addition, most EMTs were located in urban bases (50.3%), and 78 (21.8%) reported having experienced physical violence. No significant correlations were found between the demographic characteristics of the technicians and the frequency of physical violence, except base location in the last 6 months. The qualitative study also created one theme (the complexity of WPV in the prehospital setting), four categories, and ten subcategories. CONCLUSION: The study's results emphasize the need for comprehensive WPV factors in the prehospital setting. These factors can lead to identifying and improving strategies such as organizational support, improving communication and collaboration between responders, and training in de-escalation techniques. In addition, it is crucial to address the root causes of WPV such as poverty and lack of education in the community to create a safer and more supportive environment for patients and staff.

Exploring the challenges of emergency medical service providers in the initial phase of the COVID-19 pandemic: a qualitative content analysis.

BACKGROUND: As the COVID-19 pandemic continues to unfold, there has been a substantial increase in the demand for prehospital services. Emergency medical service (EMS) providers have encountered a myriad of challenges that have had a discernible impact on their professional performance. This study was designed to explore the challenges faced by EMS providers during the initial phase of the COVID-19 pandemic. METHODS: This qualitative research was conducted using a content analysis approach at emergency medical centers affiliated with Hamadan University of Medical Sciences in Iran between April and August 2021. This study included the participation of 21 EMS personnel, which was conducted using purposive sampling and semistructured interviews, and continued until data saturation was reached. The conventional content analysis method, as outlined by Graneheim and Lundman, was applied for data analysis. RESULTS: The analysis of the interview data resulted in the identification of 219 primary codes, which were then organized into ten distinct categories. These categories were further consolidated into three overarching themes: personal safety challenges, professional-organizational challenges, and threatened mental health. CONCLUSIONS: EMS personnel play a critical role in healthcare during disasters and pandemics, facing challenges that can have negative effects. Managing these challenges can impact mental health and professional well-being, but awareness, support, resources, and services can help mitigate adverse consequences.

Unveiling the performance of the prehospital Rapid Emergency Medicine Score (pREMS): How the predictive score impacts in-hospital outcomes in traumatic brain injury (TBI): A retrospective observational cohort study.

INTRODUCTION: This study aimed to evaluate the predictive accuracy of the prehospital rapid emergency medicine score (pREMS) for predicting the outcomes of hospitalized patients with traumatic brain injury (TBI) who died, were discharged, were admitted to the intensive care unit (ICU), or were admitted to the operating room (OR) within 72 h. METHODS: A retrospective cohort analysis was performed on a sample of 513 TBI patients admitted to the emergency department (ED) of Besat Hospital in 2023. Only patients of both sexes aged 18 years or older who were not pregnant and had adequate documentation of vital signs were included in the analysis. Patients who died during transport and patients who were transferred from other hospitals were excluded. The predictive power of the pREMS for each outcome was assessed by calculating the sensitivity and specificity curves and by analyzing the area under the receiver operating characteristic curve (AUROC). RESULTS: The mean pREMS scores for hospital discharge, death, ICU admission and OR admission were 11.97 ± 3.84, 6.32 ± 3.15, 8.24 ± 5.17 and 9.88 ± 2.02, respectively. pREMS accurately predicted hospital discharge and death (AOR = 1.62, P < 0.001) but was not a good predictor of ICU or OR admission (AOR = 1.085, P = 0.603). The AUROCs for the ability of the pREMS to predict outcomes in hospitalized TBI patients were 0.618 (optimal cutoff point = 7) for ICU admission and OR and 0.877 (optimal cutoff point = 9.5) for hospital discharge and death at 72 h. CONCLUSION: The results indicate that the pREMS, a new preclinical trauma score for traumatic brain injury, is a useful tool for prehospital risk stratification (RST) in TBI patients. The pREMS showed good discriminatory power for predicting in-hospital mortality within 72 h in patients with traumatic brain injury.

Exploring stress management strategies among emergency medical service providers in Iran: a qualitative content analysis.

BACKGROUND: Emergency medical service providers are frequently exposed to a variety of stressors as a result of their work environment. These stressors can have detrimental effects on both the physical and mental well-being of individuals. This study was conducted with the aim of exploring stress management strategies in emergency medical service providers. METHODS: This study was conducted in 2023 using a qualitative approach and content analysis method. A purposive sampling method was used to include 16 emergency medical system providers from Hamadan city. Semi-structured interviews, with a duration of 45-60 min, were conducted for data collection. The Data were analyzed using Graneheim and Lundman's conventional content analysis approach. RESULTS: The analysis of the interview data revealed three themes: readiness for the worst conditions, assistance based on supportive partnerships, and striving for balance. The six categories within these three themes were mental preparation, risk management, collaborations in emergency response, supportive communication, adaptive behaviors, and maladaptive responses. CONCLUSIONS: The results of this study shed light on the various stress management strategies employed by emergency medical service providers. Understanding and implementing effective stress management strategies can not only enhance the well-being of emergency medical service providers but also improve the quality of patient care. Further research and action are essential to promote the resilience and mental health of these professionals, ensuring their overall well-being and job satisfaction.

Perceptions of professional challenges by emergency medical services providers: a qualitative content analysis study.

INTRODUCTION: Emergency medical services (EMS) providers encounter a variety of challenges due to the unpredictable, uncontrollable, and dynamic conditions in the pre-hospital field. This study explored the perceived professional challenges among EMS providers. MATERIALS AND METHODS: This study was conducted using a qualitative research approach and the method of content analysis. Eighteen EMS providers were purposively selected from EMS stations in Hamadan, Iran. The collected data were then analyzed based on the Granheim and Lundman's method. RESULTS: Based on data analysis, five categories and one theme were identified. The extracted theme was professional challenges. The five categories were as follows: Ineffective policies; multicultural and multidisciplinary factors; ambulance dispatch route problems; legal issues; and abuse against the emergency medical services CONCLUSION: In general, it has been found that EMS providers encounter numerous and complex professional challenges during their work. EMS managers can utilize the findings of the present study to develop strategies for reducing the professional challenges faced by EMS providers. By doing so, they can improve the quality of care in the prehospital field.

Navigating into the unknown: exploring the experience of exposure to prehospital emergency stressors: a sequential explanatory mixed-methods.

INTRODUCTION: The unpredictability of prehospital emergencies combined with constantly changing circumstances can lead to increased stress and mental health issues among Emergency Medical Technicians (EMTs). To accurately determine the stress-inducing factors in the prehospital environment, it is important to first identify the stressful events that occur in this environment. Therefore, this study strives to provide a thorough analysis of the stressors in the prehospital environment. METHODS: Sequential explanatory mixed methods were conducted in Hamadan prehospital emergency centers in 2022. The study included 251 EMTs, who were selected through a method in the quantitative phase. The quantitative part used a questionnaire consisting of basic information and the Posttraumatic Stress Questionnaire (PCL-5). In the qualitative phase, 17 with extensive experience in dealing with prehospital stressors were selected based on their PCL-5 scores (above 33). The qualitative phase analysis was carried out using the contractual content method using the Graneheim and Ladman's approach. Statistical analyzes for the quantitative and qualitative phases were performed using SPSS 21 and maxqda 10, respectively. RESULTS: The study revealed that the EMTs had an average PTSD score of 21. 60 ± 11. 45. Multivariate linear regression analysis showed that the number of shifts had a statistically significant relationship with PTSD scores (t = 26.38, P < 0.001). The qualitative phase of the study included 17 interviews, resulting in 14 subcategories, which consisted of four categories: "the overall impact of the stress crisis on technicians," "missing links in the communication network in incident management," "professional shortcomings in pre-hospital care," and "the complex and multifaceted context of stressful pre-hospital emergencies." Additionally, the study's theme was centered around "surveying the experiences of EMTs in stressful environments." CONCLUSION: As the number of shifts increased, the primary cause of the high prevalence of PTSD in EMTs was revealed. Prehospital emergency stress can be reduced and managed more skillfully by adjusting various factors such as shortening workdays, offering continuous training, augmenting workforce, supplying ambulance equipment insurance, refraining from hiring personnel devoid of clinical training, hiring psychologists, hiring midwives in an emergency, updating prehospital protocols and guidelines, encouraging cooperation between EMTs and other relief groups, and utilizing cutting-edge technologies.

Prevalence and Related Factors of Post-Traumatic Stress Disorder in Emergency Medical Technicians; a Cross-sectional Study.

INTRODUCTION: Ongoing exposure to a variety of Pre-hospital Emergencies (PE) has placed Emergency Medical Technicians (EMTs) at serious psychiatric compromise such as Post-Traumatic Stress Disorder (PTSD). The present study aimed to evaluate the prevalence and associated factors of PTSD among EMTs. METHODS: This prospective cross-sectional study was conducted on EMTs in the Emergency Medical Services (EMS) in west of Iran. A baseline information questionnaire including personal work-related characteristics and the PTSD checklist of DSM-5 (PCL-5) were used for data collection. Non-parametric tests and multivariate linear regression were used to evaluate the associated factors of PTSD in these participants. RESULTS: Among the participants, 22% of technicians had PTSD-diagnostic criteria. The mean total PCL-5 score was 21.60 ± 11.45, while the scores were 38.02 ± 6.08 and 17.47 ± 8.36 in the PTSD-diagnosed and undiagnosed groups, respectively. The most common symptom of the clusters was negative alterations in cognition with a mean score of 7.42 ± 4.63. After adjusting confounders, the number of missions (t= 2.50, P= 0.013), work experience (t= -3.24, P= 0.001) and number of shifts (t: 26.38, P < 0.001) were significantly corelated with PCL-5 score. CONCLUSION: The results indicated that the prevalence of PTSD among EMTs personnel of Hamedan province is high. EMTs with the age of ≤ 30 years, work experience of ≤ 10 years, married status, informal employment, emergency medical technician's degree, and more than 8 shifts per month, as well as no previous training history had a higher total PCL-5 score.

Predictors of Out of Hospital Cardiac Arrest Outcomes in Pre-Hospital Settings; a Retrospective Cross-sectional Study.

INTRODUCTION: Different potential factors can affect the outcomes of Out of Hospital Cardiac Arrest (OHCA). The present study aimed to identify important factors contributing to the Return of Spontaneous Circulation (ROSC) and Survival to Hospital Discharge (SHD) in these patients. METHODS: This cross-sectional study was conducted on all the OHCA patients who underwent Cardiopulmonary Resuscitation (CPR) in emergency medical service (EMS) of Hamedan province during 2016-2017. All the relevant data were retrieved from three sources, according to Utstein's style. In addition, univariate and multivariate logistic regressions were employed to identify predictive factors of ROSC and SHD using SPSS software, version 20. RESULTS: Among the 3214 eligible patients whose data were collected, most OHCA patients were female (59.7%) with the mean age of 58 years. Moreover, the majority of OHCAs (77.8%) occurred at home during 8pm-8am (65.1%) and about 26.3% of OHCAs were witnessed, with only 5.1% bystander-initiated CPR. Furthermore, the median ambulance response time and CPR duration were 6.0 and 20 minutes, respectively. Overall, ROSC and SHD success rates were 8.3 and 4.1%, respectively. Bystander CPR was found to be the most effective predicting factor for the success rate of ROSC (AOR=3.26, P<0.001) and SHD (AOR=3.04, P<0.001) after adjusting for the Utstein variables including the patients' age, gender, cardiac disease history, arrest time, CPR duration, response time, being witnessed, bystander CPR, and endotracheal intubation (ETI). CONCLUSION: The overall success rates of ROSC and SHD were 8.3% and 4.1%, respectively. The age, ambulance response time, CPR duration, and cardiac disease history were negatively associated with the outcomes of ROSC and SHD, while being witnessed, bystander CPR, ETI, and initial shockable rhythm were positively related to both of the above-mentioned outcomes.

The Most and Least Stressful Prehospital Emergencies from Emergency Medical Technicians' View Point; a Cross-Sectional Study.

INTRODUCTION: Exposure to different prehospital emergencies (PE) may have a different impact on Emergency Medical Technicians (EMTs) based on the characteristics and circumstances of the emergency. The present study aimed to prioritize PE types according to their stressfulness as well as their correlation with post traumatic stress disorders (PTSD). METHOD: In this cross-sectional study, all EMTs in the Emergency Medical Services (EMS) of Hamadan province were invited to participate, voluntarily. The study questionnaire comprised of two parts: a) personal characteristics and prioritizing PE types in terms of their stressfulness and b) The PTSD checklist. Kruskal-Wallis test was used for examining the relationship between total PTSD score and the most and the least stressful PEs. Multivariate logistic regression was also used to predict the impact of different types of PEs on PTSD. RESULTS: 259 EMTs with the mean age of 32.79±6.16 years were studied. The total mean score of PTSD on PCL-5 was 21.60±11.45. Also, 20.1% of technicians met the criteria for PTSD. The mean age of technicians who met PTSD criteria was less than that of technicians who did not meet PTSD criteria (28 vs. 33 years, P<0.001). The most and least stressful emergencies were cardiovascular (24.7%) and environmental (26.3%) emergencies, respectively. There was a significant correlation between the most (Kruskal-Wallis=40.92, df=12, p < 0.001) and the least stressful emergencies (Kruskal-Wallis=28.22, df=15, p = 0.02) from EMTs' viewpoint and PTSD score. Multivariate logistic analysis showed that gynecologic (aOR=2.28, Wald=5.83, p=0.016) and allergic (aOR=0.12, Wald=10.16, p=0.01) emergencies were significant predictive factors of PTSD. CONCLUSION: Based on the view point of the studied EMTs, cardiac and environmental emergencies were the most and least stressful emergencies. The frequency of PTSD in this series was about 20% and it significantly correlated with younger age, lower experience, higher number of shifts, non-official employment and EMT degree. Based on multivariate logistic analysis, gynecologic and allergic emergencies were the only significant predictive factors of PTSD.

Evaluation of Airway Management Proficiency in Pre-Hospital Emergency Setting; a Simulation Study.

INTRODUCTION: Infrequency and low exposure to critically ill patients requiring airway management will lead to reduction in the skills and performance of the Emergency Medical Technicians (EMTs) over time. The present study was conducted primarily aiming to evaluate airway management in stationary ambulance simulations and identify the factors affecting Endotracheal Intubation (ETI) success rate. METHOD: This is a simulation study. The study population comprised of active EMTs in prehospital emergency bases in Hamadan province. The participants were placed at the back of an ambulance to perform the airway management scenario, which had already been prepared. To investigate the factors affecting the success (≤3 attempts) or failure rate of intubation, both unadjusted and adjusted odds ratios (95% confidence intervals) for univariate and multivariate regressions were reported. RESULTS: 184 subjects with the mean age of 33.91+6.25 years and the median work experience of 8 years were studied (54.3% with a history of training in the past year). The median number of previous intubations performed by technicians in the last year was 7 times (IQR 4-9). The total success rate at ventilation, intubation and back-up airway were 50.67%, 53.29%, and 50.0%, respectively. Out of the total 552 attempts for ETI placement, 58.2% of the technicians were able to perform ETI within 3 attempts. Univariate analysis showed that age (OR=1.06, P=0.022), previous number of ETIs (OR=2.49, P<0.001), work experience (OR=1.13, P<0.001), and previous ETI training (OR=1.85, P=0.041) were significantly associated with ETI success rate. After adjustment, previous number of ETIs (OR=2.66, P<0.001) was the most effective factor on ETI success rate. CONCLUSION: Success rate in airway management, especially ETI, is low. Therefore, improvement in modifiable factors such as increasing the number of ETIs performed and gaining experience in the same conditions as pre-hospital emergency is necessary.
