Abstract 203: Characteristics of Emergency Medical Service Responses for Adults With Cardiovascular Disease-related Chief Complaints in The United States, 2016

Background: Gaps exist in understanding the commonality of cardiovascular disease (CVD)-related responses by emergency medical services responders in the United States (US) community setting. Objective: We examined characteristics of CVD-related responses among US adults with 9-1-1 emergency medical services (EMS) responses in a national database. Methods: The 2016 National Emergency Medical Services Information System (NEMSIS) database (Version 2.2.1) from 49 states was used. CVD-related chief complaints were defined by data element E09_12 in the NEMSIS code book. Exclusions were EMS cancellations, persons not found, those with unknown sex, and patients aged <18 years. Rates (per 1,000 EMS responses) were calculated for total population and by patient demographics. Chi-square statistical tests were used to assess associations. Percentages of CVD-related chief complaints were calculated for EMS responses (incident patient disposition, type of destination, and reasons for destination), and clinical characteristics (provider’s primary impression, provider’s secondary impression, primary symptom, and EMS condition code). Results: We identified over 19.8 million EMS responses among adults aged ≥18 years old in 2016, including 1,336,684 (67.4 per 1,000 EMS responses) with CVD-related chief complaints. Rates of CVD-related chief complaints per 1,000 EMS responses for females (68.5), patients aged 65-74 years old (87.7), Hawaiian Pacific Islanders (83.6), whites (73.4), and those living in the South census region (72.8) were significantly higher than their respective counterparts. Among EMS responses, most CVD-related chief complaints were treated and transported by EMS (83.1%), and of those transported by EMS, 83.5% were transported to a hospital. Reasons for hospital destinations among adults with CVD-related chief complaints were patient’s preferred hospital (34%) and closest facility (32.9%). Most CVD-related chief complaints were chest pain or discomfort according to provider’s primary impression (48%) and provider’s secondary impressions (6.1%). Finally, pain (46.2%) was the most frequently reported condition as primary symptom among EMS patient with CVD-related chief complaints. Conclusion: Approximately 1-in-15 EMS (9-1-1) responses among adults involved a CVD-related chief complaint. Future research could focus on trends for CVD-related EMS responses overtime. Keyword: 9-1-1 emergency system, prehospital cardiovascular disease, CVD-related events.

EMSContExt: EMS Protocol-Driven Concept Extraction for Cognitive Assistance in Emergency Response

This paper presents a technique for automated curation of a domain-specific knowledge base or lexicon for resource-constrained domains, such as Emergency Medical Services (EMS) and its application to real-time concept extraction and cognitive assistance in emergency response. The EMS responders often verbalize critical information describing the situations at an incident scene, including patients' physical condition and medical history. Automated extraction of EMS protocol-specific concepts from responders' speech data can facilitate cognitive support through the selection and execution of the proper EMS protocols for patient treatment. Although this task is similar to the traditional NLP task of concept extraction, the underlying application domain poses major challenges, including low training resources availability (e.g., no existing EMS ontology, lexicon, or annotated EMS corpus) and domain mismatch. Hence, we develop EMSContExt, a weakly-supervised concept extraction approach for EMS concepts. It utilizes different knowledge bases and a semantic concept model based on a corpus of over 9400 EMS narratives for lexicon expansion. The expanded EMS lexicon is then used to automatically extract critical EMS protocol-specific concepts from real-time EMS speech narratives. Our experimental results show that EMSContExt achieves 0.85 recall and 0.82 F1-score for EMS concept extraction and significantly outperforms MetaMap, a state-of-the-art medical concept extraction tool. We also demonstrate the application of EMSContExt to EMS protocol selection and execution and real-time recommendation of protocol-specific interventions to the EMS responders. Here, EMSContExt outperforms MetaMap with a 6% increase and six times speedup in weighted recall and execution time, respectively.

A Systematic Review of Workplace Violence Against Emergency Medical Services Responders.

Emergency Medical Service (EMS) responders deliver patient care in high-risk, high-stress, and highly variable scenarios. This unpredictable work environment exposes EMS responders to many risks, one of which is violence. The primary goals of this systematic literature review were to (1) define the issue of violence experienced by EMS responders and (2) identify the risk factors of violence associated with the EMS profession. An innovative inclusion of industrial literature with traditional peer-reviewed literature was performed. Of 387 articles retrieved, 104 articles were assessed and reviewed. Career exposure for EMS responders to at least one instance of verbal and/or physical violence was between 57 and 93 percent. There is a great need for rigorously designed, nationally representative examinations of occupational exposures in order to better understand the temporal associations of violence, cumulative occupational stressors, and the outcomes of physical and psychosocial injuries that are occurring as a result of exposures to violence.

Mitigating Violence Against First Responder Teams: Results and Ideas From the Hackmanathon

First responders are on the front line of patient care and service, but research has shown that they are also on the front line of exposure to violence. Currently, there is a lack of evidence-based interventions that prepare first responders to handle violence on the job. With the increase in emergency medical services (EMS) call volume and reports of at least 57% of the EMS responders having experienced workplace violence, there is a need to develop scientifically systematic solutions to improve emergency responder safety. Using an adapted version of the hackathon method, academic scholars and practitioner conference attendees at the Interdisciplinary Network for Group Research (INGRoup) Conference were deployed into three multidisciplinary teams to analyze the issue and develop specific solutions. These solutions offer unique interventions to improve first responder safety.

PPE Misuse and its Effect on Infectious Disease Among EMS in Saudi Arabia


 
 
 Emergency Medical Services (EMS) responders provide medical services in diverse, unique and dangerous environments. EMS provides care to diverse and mobile populations who are likely to contract infectious diseases. In addition to responding to the emergency situations, the EMS are also attending to the homeless, trauma victims and nursing home patients in addition to critically ill patients with diverse diseases and infections. Like most healthcare professionals, EMS responders are faced with increased exposure to infectious conditions. As a result, they are concerned with their safety and preventive measures against any infection. The aim of this study is to assess whether EMS follows the standard guidelines provided by the Saudi Red Crescent Authority (SRCA) to avoid being infected. Using the standard SRCA observational tool, EMS Red Crescent workers in various stations, EMS station 1 (17 paramedics), EMS station 2 (11 paramedics) and EMS station 3 (16 paramedics), were observed on whether they follow the provided standard Personal Protective Equipment (PPE) guidelines to avoid being infected whether by MERS or other diseases. The results indicate that most of the EMS staff did not implement the PPE standard procedure or failed to demonstrate the skills on the application of the standards. Failure to follow the safety standards and guidelines is the main cause of infections among the EMS staff (Disaster Med Public Health Preparedness. 2018). Therefore, there is need to provide comprehensive training on the standard guidelines and safety measures to prevent the occurrences of infections among the EMS workforce.
 
 

Creation of a Systems-Level Checklist to Address Stress and Violence in Fire-Based Emergency Medical Services Responders

Between 57 and 93% of Emergency Medical Services (EMS) responders reported having experienced verbal or physical violence at least once in their career. Therefore, the primary goal of this study was to develop a systems-level checklist for violence against fire-based EMS responders using findings from a systematic literature review and outcomes from a national stakeholder meeting. First, a literature review of violence against EMS responders resulted in an extensive list of 162 academic and industrial publications. Second, from these sources, 318 potential candidate items were developed. Third, Q-methodology was employed to categorize, refine, and de-duplicate the items. Fourth, ThinkLet systems facilitated consensus-building, collaboration, and evaluation of the checklist with diverse subject matter experts representing 27 different EMS organizations, government, academia, labor unions, and fire departments during a two-day consensus conference. The final SAVER checklist contains 174 items organized by six phases of EMS response: pre-event, traveling to the scene, scene arrival, patient care, assessing readiness to return to service, and post-event. So called pause points for the individual EMS responder were incorporated at the end of each of phase. Overall, 47.5% of votes across all phases rated items as most feasible, 33.7% as less feasible, and 11.6% as extremely difficult. The SAVER systems-level Checklist is an innovative application of traditional checklists, designed to shift the onus of safety and health from that of the individual first responder to the organization by focusing on actions that leadership can institute through training, policy, and environmental modifications.

"Felony assault should stick:" Assaulted EMS responders' frustration and dissatisfaction with the legal system.

IntroductionThe prevalence of violence to first responders is reported in ranges of approximately 40% to 90%. Pennsylvania has a felonious assault statute to address such violence, but the prosecutorial process has been noted to cause first‐responder dissatisfaction.MethodsAn exploratory qualitative study using individual interviews with snowball sampling was conducted with the Philadelphia District Attorney's office to understand the prosecutorial process when a first responder is assaulted and injured in a line of duty. The Philadelphia Fire Department provided a list of first responders who sustained a work‐related injury from a patient or bystander assault so that particular cases could be discussed during the interviews.ResultsEmergent themes fell into two categories: factors that lead to a charge (prosecutorial merit, intent, and victim investment), and the judge's discretion in sentencing (“part of the job” mentality, concern for the defendant, and the justice system's offender focus). Immediately actionable tertiary prevention recommendations for fire departments, labor unions, and district attorney's offices were developed.ConclusionViolence against fire‐based emergency medical service (EMS) responders is a persistent and preventable workplace hazard. While felonious assault statutes express society's value that it is unacceptable to harm a first responder, this study found that such statutes failed to provide satisfaction to victims and that support when going through the court process is lacking. Assaulted EMS responders, their employers, and labor unions would benefit from the recommendations provided herein to help them extract a stronger sense of procedural justice from the legal process.

Abstract WP298: Communication Center Guided Prehospital Stroke Assessment Scoring has High Inter-rater Agreement

Introduction: We are prospectively validating a model of communication center guided prehospital identification of stroke patients with large vessel occlusion (LVO). Goal: Assess the inter-rater agreement between a Vascular Neurologist and Alabama Trauma Communication Center (ATCC) personnel in diagnostic classification of stroke patients. Methods: The ATCC is staffed by paramedic-trained dispatchers who field calls from Emergency Medical Service (EMS) responders and maintain up-to-the-minute status of hospitals and resources 24/7. We trained ATCC personnel in stroke pathology, pathophysiology, appropriate patient selection for thrombolytic and endovascular therapies; and the previously derived 6 point Emergency Medical Stroke Assessment (EMSA). ATCC personnel guided EMS responders in the Birmingham Regional Emergency Medical Services System (BREMSS), and paged-out a hospital stroke prenotification that included specific EMSA scale items (gaze, facial droop, arm drift, leg drift, naming, and repetition). All interactions between the ATCC and EMS responders were recorded, allowing review of audio files and ongoing quality improvement. ATCC personnel and a vascular neurologist separately reviewed recordings and assigned scores to each patient according to the deficit stated by the EMS. To determine inter-rater reliability we utilized the Kappa statistic with a significance level of 0.05, and 95% confidence intervals (CI). Results: We sampled a total of 146 patients. We observed statistically significant agreement between the raters for all EMSA components, with 71% (CI=45-97%, p<0.0001) agreement in rating the gaze component, 54% (CI=26-82%, p=0.002) for the face, 57% (CI=29-85%, p=0.001) for the arm, 60% (CI=33-86%, p<0.0006) for the leg, 56% (CI=30-81%, p<0.001) for naming, and 34% (CI=6-61%, p<0.04) for repetition. Conclusion: We conclude that there is moderate to substantial agreement in most stroke assessment items by a paramedic staffed communication center and a vascular neurologist. There was only fair inter-rater agreement for repetition. Paramedic-trained dispatchers can reliably guide EMS responders and score the Emergency Medical Stroke Assessment.

Abstract TP313: Communication Center Guided Prehospital Stroke Assessment Has Sustained Ability to Identify Patients With Large Vessel Occlusion

Introduction: There is need for sustainable models of effective prehospital stroke triage. Goal: Prospectively validate communication center guided prehospital identification of stroke patients with large vessel occlusion (LVO). Methods: We trained Alabama Trauma Communication Center (ATCC) paramedics in the previously derived 6 point Emergency Medical Stroke Assessment (EMSA). ATCC staff guided Emergency Medical Service (EMS) responders in the Birmingham Regional Emergency Medical Services System (BREMSS), and paged-out a hospital prenotification that included specific EMSA items (gaze, facial droop, arm drift, leg drift, naming, and repetition). Ongoing quality improvement was designed to enable the ATCC staff to effectively guide EMS responders. We derived the sensitivity, specificity, negative likelihood ratio (LR-), positive likelihood ratio (LR+), and receiver operator characteristics area under the curve (AUC) and 95% confidence intervals (CI) of ATCC guided EMSA for predicting a discharge diagnosis of LVO for patients transported to the University of Alabama at Birmingham. Results: We enrolled 521 patients from September 2016 through February 2018. Patients who only responded to pain (n=29, 5.6%) or who were unresponsive (n=21, 4%) were excluded. Of 471 patients analyzed, 247(52%) had a discharge diagnosis of stroke, including 182 (74%) acute ischemic stroke, 36 (14%) intracerebral hemorrhage, and 29 (11%) transient ischemic attack. There were 45 (18%) stroke patients with proximal LVO, including 31 middle cerebral artery stem, 12 internal carotid artery, and 2 basilar artery. Overall, an EMSA score ≥ 4 had sensitivity = 75.6%, specificity = 62.2%, LR- = 0.39, and LR+ = 2.00 for proximal LVO. During the first 9 months of the study, the EMSA AUC = 0.61 (CI = 0.45 – 0.77) compared to an AUC = 0.74 (CI = 0.64 – 0.84) during the second 9 month period of the study. Conclusions: EMS stroke medical control based on communication center guided prehospital stroke assessment and ongoing quality improvement is feasible and results in sustained ability to identify patients with LVO. Further studies are needed to evaluate the impact of guided prehospital triage of patients with suspected LVO on health outcomes.

Perceptions by Families of Emergency Medical Service Interventions During Imminent Pediatric Out-of-Hospital Death

Objective: To understand how family members view the ways Emergency Medical Services (EMS) and other first responders interact with distressed family members during an intervention involving a recent or impending pediatric death.Methods: In depth interviews with 11 grieving parents of young children and survey results from 4 additional grieving parents of adult children were conducted as part of a larger study on effective ways for EMS providers to interact with distressed family members during a pediatric death in the field. The responses were analyzed using qualitative content analyses.Results: Family reactions to the crisis and the professional response by first responders were critical to family coping and getting necessary support. There were several critical competencies identified to help the family cope including: (1) that first responders provide excellent and expeditious care with seamless coordination, (2) allowing family to witness the resuscitation including the attempts to save the child’s life, and (3) providing ongoing communication. Whether the child is removed from the scene or not, keeping the family apprised of what is happening and why is critical. Giving tangible forms of support by calling friends, family, and clergy, along with allowing the family time with the child after death, giving emotional support, and follow-up gestures all help families cope.Conclusion: The study generated hypothetical ways for first responders to interact with distressed family members during an OOH pediatric death.

Medical Needs Documented by Emergency Medical Services (EMS) Responders to Areas Affected by Typhoon Haiyan in the Philippines: Implications on Disaster Response Policy

Background. Despite existing disaster preparedness policies in the Philippines, there has not been any validated assessment of the quality of disaster medical response, which would require reliable aggregate data on patient diagnoses and management.
 Objective. This mixed-methods study documented the diagnoses, triage classification and case management of patients seen by Philippine EMS groups who responded to the Typhoon Haiyan disaster in the Philippines in November and December 2013, as well as difficulties associated in gathering these data, using the Utstein-style Template for Uniform Data Reporting of Acute Medical Response in Disasters as framework.
 Methods. Three hundred (300) individuals vetted by EMS organizations were invited to answer a survey modeled after the Utstein-style template, and submit tallies of patients seen. Out of 52 responses received, policy recommendations were subsequently generated on concerns assessed by the template using the nominal group technique.
 Results. The submitted data yielded a total of 41,202 patients with information on age, sex, and diagnosis; 19,193 with triage classification; and 27,523 with information on case management. The focus group discussion underlined the absence of a standard communication and information management system. Participants recommended establishing such a system, and highlighted the role of the Department of Health – Health Emergency Management Bureau in coordinating disaster medical response efforts and information management.
 Conclusion. This study underlines the importance of effective communication, and multisectoral coordination, to generate reliable data and thus, facilitate resource allocation for disaster medical response.

Enabling Factors, Hindrances, and Self-perceived Level of Preparedness of Typhoon Haiyan Emergency Medical Services (EMS) Responders

Background. Despite the implementation of policies related to disaster risk reduction and management in the Philippines, the response after Typhoon Haiyan in November 2013 was hampered by operational challenges.
 Objective. The purpose of this study was to document disaster response experiences of Typhoon Haiyan from field level emergency medical service (EMS) responders, a key component of the disaster response, specifically the enabling factors and hindrances to disaster medical response activities, including their self-perceived level of preparedness in these activities.
 Methods. In this mixed-methods study, 52 respondents identified enabling factors and hindrances to their disaster response and their corresponding self-perceived level of preparedness. In a subsequent focus group discussion, the researchers used the nominal group technique to process the respondents’ experiences.
 Results. The respondents identified factors that enabled or hindered their response activities such as coordination, stress debriefing, infrastructure, and preparedness. Furthermore, an average of 33% of the respondents said they were adequately prepared to deliver the necessary medical services during the disaster response, thus validating previous studies on preparedness and disaster response operations.
 Conclusion. The government should critically examine its cluster approach to disaster response and consider an integrated, inclusive, and proactive approach in disaster planning.

Acceptability and perceived utility of drone technology among emergency medical service responders and incident commanders for mass casualty incident management.

This study seeks to understand the acceptability and perceived utility of unmanned aerial vehicle (UAV) technology to Mass Casualty Incidents (MCI) scene management. Qualitative questionnaires regarding the ease of operation, perceived usefulness, and training time to operate UAVs were administered to Emergency Medical Technicians (n = 15). A Single Urban New England Academic Tertiary Care Medical Center. Front-line emergency medical service (EMS) providers and senior EMS personnel in Incident Commander roles. Data from this pilot study indicate that EMS responders are accepting to deploying and operating UAV technology in a disaster scenario. Additionally, they perceived UAV technology as easy to adopt yet impactful in improving MCI scene management.

Prehospital Management of Acute Stroke in Rural versus Urban Responders.

Objective:Stroke guideline compliance of rural Canadian prehospital emergency medical services (EMS) care in acute stroke is unknown. In this quality assurance study, we sought to compare rural and urban care by prehospital EMS evaluation/management indicators from patients assessed at an urban Canadian stroke center.Materials and Methods:One hundred adult patients were randomly selected from the stroke registry. Patients were transported through Rural EMS bypass protocols or urban EMS protocols (both bypass and direct) to our stroke center between January and December 2013. Patients were excluded if they were first evaluated at any other health center. Prehospital care was assessed using ten indicators for EMS evaluation/management, as recommended by acute stroke guidelines.Results:Compliance with acute stroke EMS evaluation/management indicators were statistically similar for both groups, except administrating a prehospital diagnostic tool (rural 31.8 vs. urban 70.3%; P = 0.002). Unlike urban EMS, rural EMS did not routinely document scene time.Conclusion:Rural EMS responders’ compliance to prehospital stroke evaluation/management was similar to urban EMS responders. Growth areas for both groups may be with prehospital stroke diagnostic tool utilization, whereas rural EMS responders may also improve with scene time documentation.

Abstract TP229: Change Takes Time: EMS as the Spark Plug for Faster Acute Ischemic Stroke Care

Introduction: It is well documented that a Prehospital Stroke Alert (PHSA) protocol leads to decreased treatment times for stroke patients. Outcomes measured typically include Door to Physician (DTP), Door to CT (DTCT), and Door to Needle (DNT) times. Our comprehensive stroke center’s PHSA system has been in place since 2012. This study evaluates 3 specific endpoints. First, Emergency Medical Services (EMS) improve their recognition of stroke symptoms as they gain experience with PHSA. Second, a PHSA protocol decreases intervention times of DTP, DTCT, and DNT over a study period of 3 years. Third, when patients present to our Neurologic Emergency Department (Neuro ED) as a PHSA, rather than a non-PHSA, the intervention times are markedly decreased, and acute ischemic stroke care is significantly expedited. Methods: A retrospective chart review was conducted for patients who presented to our hospital with an admitting diagnosis of stroke from 2012-2014. Patients were screened for presentation to the Neuro ED and further stratified based on whether a PHSA was called. PHSA was called if EMS deemed the patient’s Cincinnati Stroke Scale score as positive, and symptom onset was within 6 hours. We recorded DTCT, DTP, and DTN times over the years for all patients meeting these inclusion criteria. Results: Three hundred and five patients with an admission diagnosis of stroke were seen in the Neuro ED (Hours are 0700-1800, 7 days a week) from 2012 to 2014, 128 of which presented as PHSAs. EMS responders accurately diagnosed stroke in 82% of cases. Previously, EMS assessment of stroke was accurate only 66% of the time. PHSA patients had decreased DTP, DTCT, and DTN times over the 3 year period. When comparing the PHSA group to non-PHSA group, statistically significant differences were found in DTP and DTCT times within each year (p≤0.0001). Discussion: In conclusion, gaining experience with a PHSA protocol did in fact lead to EMS better recognizing stroke symptoms, reduction in the times of delivery of care for acute ischemic stroke patients over the years 2012-2014, and a markedly statistically significant difference in intervention times if patients were seen as a PHSA as opposed to a non-PHSA.

Hazard perception in emergency medical service responders

The perception of on-road hazards is critically important to emergency medical services (EMS) professionals, the patients they transport and the general public. This study compared hazard perception in EMS and civilian drivers of similar age and personal driving experience. Twenty-nine EMS professionals and 24 non-professional drivers were given a dynamic hazard perception test (HPT). The EMS group demonstrated an advantage in HPT that was independent of simple reaction time, another indication of the validity of the test. These results are also consistent with the view that professional driving experience results in changes in the ability to identify and respond to on-road hazards. Directions for future research include the development of a profession-specific hazard perception tool for both assessment and training purposes.

Using On-scene EMS Responders' Assessment and Electronic Patient Care Records to Evaluate the Suitability of EMD-triaged, Low-acuity Calls for Secondary Nurse Triage in 911 Centers.

Using the Medical Priority Dispatch System (MPDS) - a systematic 911 triage process - to identify a large subset of low-acuity patients for secondary nurse triage in the 911 center is a largely unstudied practice in North America. This study examines the ALPHA-level subset of low-acuity patients in the MPDS to determine the suitability of these patients for secondary triage by evaluating vital signs and necessity of lights-and-siren transport, as determined by attending Emergency Medical Services (EMS) ambulance crews. The primary objective of this study was to determine the clinical status of MPDS ALPHA-level (low-acuity) patients, as determined by on-scene EMS crews' patient care records, in two US agencies. A secondary objective was to determine which ALPHA-level codes are suitable candidates for secondary triage by a trained Emergency Communication Nurse (ECN). In this retrospective study, one full year (2013) of both dispatch data and EMS patient records data, associated with all calls coded at the ALPHA-level (low-acuity) in the dispatch protocol, were collected. The primary outcome measure was the number and percentage of ALPHA-level codes categorized as low-acuity, moderate-acuity, high-acuity, and critical using four common vital signs to assign these categories: systolic blood pressure (SBP), pulse rate (PR), oxygen saturation (SpO2), and Glasgow Coma Score (GCS). Vital sign data were obtained from ambulance crew electronic patient care records (ePCRs). The secondary endpoint was the number and percentage of ALPHA-level codes that received a "hot" (lights-and-siren) transport. Out of 19,300 cases, 16,763 (86.9%) were included in the final analysis, after excluding cases from health care providers and those with missing data. Of those, 89% of all cases did not have even one vital sign indicator of unstable patient status (high or critical vital sign). Of all cases, only 1.1% were transported lights-and-siren. With the exception of the low-acuity, ALPHA-level seizure cases, the ALPHA-level patients are suitable to transfer for secondary triage in a best-practices, accredited, emergency medical dispatch center that utilizes the MPDS at very high compliance rates. The secondary nurse triage process should identify the few at-risk patients that exist in the low-acuity calls.

Occupational physical fitness and eating attitudes of emergency medical services students in Riyadh

Aims: To compare occupational, physical fitness and eating attitudes among students at a college for emergency medical services (EMSs) in Riyadh, Saudi Arabia, with American Council on Exercise (ACE) international physical fitness guidelines. Settings and Design: Seventy-three EMS students with a mean age and body mass index of 20.7 ± 1.1 years and 26.3 ± 6.6, respectively, were randomly selected. Participants were asked to complete three suggested ACE physical fitness tests and the Eating Attitudes Test-26 questionnaire. Materials and Methods: We used test protocols and administration to calculate student group percentages and compare results with the ACE guideline test-termination criteria. Statistical Analysis Used: We used a one-sample t-test to assess differences in obtained versus reference scores. Results: Moderate to strong correlations were clearly observed between most variables, especially in the trunk (flexor - extensor) endurance test (r = 0.67, P < 0.01). In addition, a strong correlation between left- and right-sided trunk lateral endurance was observed (r = 0.76, P < 0.01). Regarding ACE guidelines for EMS practitioners, the subjects of this study were not significantly physically fit. Finally, only 16.9% of students exhibited eating disorder risks requiring professional attention. Conclusions: The low level of core physical fitness indicates the need for a special exercise program with a primary focus on EMS responders' abilities to fulfill occupational requirements. A physical exercise intervention program that emphasizes static balance, postural control, and overall flexibility and strength might be important for the prevention of occupational risk among EMS students.
