Treatment Outcome, Pattern of Injuries and Associated Factors Among Traumatic Patients Attending Emergency Department of Dessie City Government Hospitals, Northeast Ethiopia: A Cross-Sectional Study.

Traumatic injuries are a major cause of emergency room visits and hospital workload, and they are a global health concern. Therefore, this study aimed to assess the pattern of injuries, treatment outcomes, and associated factors among traumatic patients attending the emergency department of Dessie City Government Hospitals, Northeast Ethiopia. An institutional-based retrospective cross-sectional study was conducted among 415 traumatic patients selected by using a systematic random sampling technique, from July 1, 2019, to June 30, 2022. Data were collected through document review. The data were presented with frequency tables and graphs. Data were entered using EPI data version 4.6 and exported to SPSS version 26 for analysis. Both bi-variable and multivariable logistic regression analyses were performed to analyze the relationship between the independent variable and the outcome variable. As a measure of association, the adjusted odds ratio was utilized, which has a 95% confidence level. Statistically significant variables were those with a p-value of less than 0.05. From 420 patient charts, 415 traumatic patients' charts were reviewed in this study, with a response rate of 98.8%. The prevalence of good treatment outcomes among traumatic patients was found to be 67% [95% CI: 62.2, 72.0]. In the final multivariable analysis, having comorbidity [AOR=, 0.31 95% CI: 0.16, 0.60], arriving within one hour [AOR=4.79, 95% CI: 2.10, 10.94], arriving two up to twenty-four hours [AOR=2.25, 95% CI: 1.34, 3.78] and being conscious at admission [AOR=1.82, 95% CI: 1.02, 3.26] had a significant association with a good treatment outcome among traumatic patients. Trauma constitutes a major public health problem in our setting and contributes significantly to unacceptably high morbidity and mortality. Interventions should be targeted at urgent injury prevention and management strategies, along with the establishment of a pre-hospital emergency medical service system.

The effects of Pre-hospital Trauma Life Support (PHTLS) training program on the on-scene time interval

BackgroundRecent studies have shown that reducing pre-hospital time could improve the outcomes of trauma victims. Due to the importance of pre-hospital time management, this study aims to determine the effects of the Pre-hospital Trauma Life Support (PHTLS) training program on the on-scene time interval reduction.MethodsThe PHTLS training program was implemented based on global standards for pre-hospital emergency technicians. The research tool was a questionnaire designed by the Ministry of Health and Medical Education in Iran. The mean on-scene time interval was calculated before, after and one month after the intervention in the control (n = 32) and experimental group (n = 32). The data were analyzed using SPSS.ResultsThe mean on-scene time interval in the target group (one month after intervention) has been significantly lower than that of the control group. Moreover, the mean and standard deviation from the on-scene time interval in the target group has been reduced from 17.6 ± 5.5 (before intervention) to 12 ± 3.8 min (one month after intervention) which was statistically significant.ConclusionThe implementation of the PHTLS training program can lead to the reduction of on-scene time interval. Therefore, considering the role of reducing on-scene time intervals on victims’ survival, the integration of the PHTLS training programs with pre-hospital emergency medical service systems seems inevitable.

Pattern and Outcomes of Injuries among Trauma Patients in Gedeo Zone, Dilla, South Ethiopia: A 5 Years Retrospective Analysis.

Injury has become a life threatening community health problem associated with significant mortality and morbidity worldwide. The aim of this study was to assess the burden of injury in Dilla University Hospital. Institution-based retrospective cross-sectional study was conducted from January 2015 to June 2019. Data was collected using questionnaire adapted from WHO injury surveillance guideline. Bivariate and multivariate logistic regressions were performed to determine the factors associated with hospital mortality. Road traffic accident was the commonest cause of injury 178(47.3%) followed by interpersonal violence 113(30.1%). Revised trauma score (RTS) < 10 (AOR=2.5; 95% CI, 1.8-25.6), Glasgow coma scale (GCS) (AOR =0.3; 95% CI, 0.13-0.5), length of hospitalization (LOS) 1-7 days (AOR=0.1; 95% CI, 0.01-0.8) and time of arrival >24hr were predictors of mortality in a patient with injury. Lower extremity injury was common and mostly associated with RTA. Pre-hospital emergency medical service system and trauma registry need to be established to decrease the burden of injury.

병원 전 응급의료체계에서 간호사의 업무범위에 대한 소고(小考)

간호사는 의료법 상 의료인으로서 의료기관에서 진료의 보조 등의 업무를 수행한다. 의료인인 간호사는 119 구조․구급에 관한 법률에 근거 구급대원으로서 병원 전 단계 응급의료체계에서 응급환자를 대상으로 응급의료를 제공한다. 병원 전 응급의료체계에서 업무를 수행하는 간호사의 업무범위는 의료법 상 포괄적으로 규정되어 있는 업무를 판례 등을 통해 구체화되어 왔다. 반대로 응급구조사의 업무범위는 응급의료법에 의해 구체적 행위를 열거하는 방식으로 규정되어 있다. 병원 전 단계 응급의료체계에서 응급의료종사자로서 업무를 수행하는 간호사의 업무범위는 대상 환자의 긴급성, 응급의료기관으로의 이송 중이라는 점, 통신 상의 의료지도라는 특수성을 고려하여 간호사의 업무범위를 의료기관 내에서와 달리 적용하여 해석되어야 한다. 따라서 상대적으로 병원 전 단계에서 간호사가 응급구조사보다 넓은 업무범위가 인정되고 이것이 정책목표에도 부합된다.

Physician-manned prehospital emergency care in tertiary emergency centers in Japan.

AimUse of a physician‐manned prehospital emergency medical service (EMS) has recently become widespread in Japan. Understanding the epidemiology of critically ill patients is essential for planning national and regional physician‐manned prehospital EMS systems. However, current knowledge on patients receiving physician‐manned prehospital EMS is sparse. The present study aimed to determine the clinical features of critically ill patients with and without physician‐manned prehospital EMS, using a national inpatient database in Japan.MethodsUsing the Japanese Diagnosis Procedure Combination inpatient database, we identified all hospitalized patients transported to tertiary emergency centers by physician‐manned EMS or EMS without a physician from April 2014 to March 2015. We collected data on patient characteristics, in‐hospital mortality, admission diagnoses, advanced life support interventions, and incidence of critical illnesses.ResultsWe identified 497,911 hospitalized patients transported to tertiary emergency centers by EMS. Of these, 15,507 (3%) patients were hospitalized by physician‐manned EMS. The majority of admission diagnoses in the physician‐manned EMS group were classified “diseases of the circulatory system” (45%) and “injury, poisoning and certain other consequences of external causes” (34%). The rates of in‐hospital mortality, advanced life support interventions, and critical illnesses in the physician‐manned EMS group were 22%, 51%, and 53%, respectively. The median incidences of hospitalized patients by physician‐manned EMS, advanced life support interventions, and critical illnesses were 12, 137, and 205 per 100,000 persons per year in facilities with physician‐manned EMS, respectively.ConclusionOur study indicates that physician‐manned EMS is dispatched to a relatively small proportion of critically ill patients in Japan.

Assessment of pre-hospital emergency medical services in low-income settings using a health systems approach

Emergency medical services (EMS) is defined as the system that organizes all aspects of care provided to patients in the pre-hospital or out-of-hospital environment. Hence, EMS is a critical component of the health systems and is necessary to improve outcomes of injuries and other time-sensitive illnesses. Still there exists a substantial need for evidence to improve our understanding of the capacity of such systems as well as their strengths, weaknesses, and priority areas for improvement in low-resource environments. The aim was to develop a tool for assessment of the pre-hospital EMS system using the World Health Organization (WHO) health system framework. Relevant literature search and expert consultation helped identify variables describing system capacity, outputs, and goals of pre-hospital EMS. Those were organized according to the health systems framework, and a multipronged approach is proposed for data collection including use of qualitative and quantitative methods with triangulation of information from important stakeholders, direct observation, and policy document review. The resultant information is expected to provide a holistic picture of the pre-hospital emergency medical services and develop key recommendations for PEMS systems strengthening.

The 2017 International Joint Working Group White Paper by INDUSEM, the Emergency Medicine Association and the Academic College of Emergency Experts on Establishing Standardized Regulations, Operational Mechanisms, and Accreditation Pathways for Education and Care Provided by the Prehospital Emergency Medical Service Systems in India.

The government of India has done remarkable work on commissioning a government funded prehospital emergency ambulance service in India. This has both public health implications and an economic impact on the nation. With the establishment of these services, there is an acute need for standardization of education and quality assurance regarding prehospital care provided. The International Joint Working Group has been actively involved in designing guidelines and establishing a comprehensive framework for ensuring high-quality education and clinical standards of care for prehospital services in India. This paper provides an independent expert opinion and a proposed framework for general operations and administration of a standardized, national prehospital emergency medical systems program. Program implementation, operational details, and regulations will require close collaboration between key stakeholders, including local, regional, and national governmental agencies of India.

Actual Operation of Private Prehospital Emergency Medical Service Systems in Certain Regions of South Korea

This study aims to analyze the actual conditions of the managers and employees of private emergency medical service systems and to provide basic data for the activation of a private Emergency Medical Service System (EMSS). Structured questionnaires were distributed to the managers and employees of private emergency patient transport services. From August 1 to October 30, 2013, a survey was conducted face-to-face by personal visits and the collected data were processed using IBM SPSS Statistics 20.0. The average monthly income of the managers was 13.69 million won and net profit after operating expenses was 3.3 million won. Of total employees, 62.7% were in their twenties, while 68.7% earned an average of 1.5 million won or less a month and 31.3% more than 1.5 million won a month. This study found that the operational situation of the private transport services was very poor and that they were poorly managed; therefore, in order to achieve qualitative improvements in public health care, there is a need for private transport services to obtain financial assistance for Emergency Medical Service (EMS) and to have stable administration.

Assessing and Exploring the Competency of Prehospital Emergency Medical Service Personnel in Klang Valley, Malaysia: a Mixed Method Approach

Introduction: The notion of competency in pre-hospital emergency medical service (EMS) personnel is mainly focused on the professional proficiency that he/she has to provide intervention outside of hospital setting. Consequently, the effectiveness of pre-hospital EMS performance very much depends upon the capability of the personnel at the scene and as well during transport to the definitive care center. The aim of this study is to appraise and explore the competency of pre-hospital care staff and provide strategies for improvement. Methods: A mixed method approach combining the qualitative and quantitative study design. Of 134 staffs only 111(82.84%) returned the questionnaire. Nine semi-structured interviews and two focus group discussions were performed. The main informants were nurses/assistant medical officers, nurse/assistant medical officer administrators, and emergency physicians. Results: From the quantitative finding on the competency of staff handling pre-hospital EMS, all had the essential knowledge and skills. However, most of them reported not having good knowledge and skills for invasive procedures (31%-61%), include giving medications (61%-66%). The qualitative information provided insight about the issues and strategies for the personnel in regards to competency. All the relevant qualitative data were merged into 5 categories relating issues and 5 categories to strategies that could affect the competency of the personnel. Conclusion: Pre-hospital EMS systems need to consider that the competency of pre-hospital EMS personnel has to come along with the responsible attitude of the staff itself, the support of medical direction, clear protocol for guiding them whenever needed, and continuous professional-development courses require them to maintain their professional proficiency.

Prehospital System Development in Jaffna, Sri Lanka

The building of prehospital emergency medical care systems in developing and lower middle-income countries (as defined by the World Bank) is a critical step in those countries' efforts to reduce unnecessary morbidity and mortality. This case report presents the development of a prehospital care system in Jaffna District, Sri Lanka and provides the results of the system's first year of operations, the likely reasons for the results, and the prospects for sustained operations of the system. The goal of this report is to add to the literature surrounding Emergency Medical Services (EMS) in developing countries by providing insight into the implementation of a prehospital emergency care system in developing and lower middle-income settings. The level of utilization and the financial performance of the system during its first year of operation were analyzed using data from the Jaffna Regional Director of Health Services (RDHS) Call Center database and information from the implementing organization, Medical Teams International. The system responded to >2000 emergency calls in its first 11 months of operation. The most utilized ambulance of the system experienced only a US $13.50 loss during the first 12 months of operation. Factors such as up-front support, a systematic approach, and appropriateness contributed to the successful implementation of the Jaffna prehospital EMS system. The implementation of a prehospital EMS system and its functioning were successful in terms of utility and, in many regards, financial stability. The system's success in development may serve as a potential model for implementing prehospital emergency medical care in other developing and lower middle-income country settings, keeping in mind factors outside of the system that were integral to its developmental success.

Stroke Statistics in Korea: Part II Stroke Awareness and Acute Stroke Care, A Report from the Korean Stroke Society and Clinical Research Center For Stroke

The aim of the current Part II of Stroke Statistics in Korea is to summarize nationally representative data on public awareness, pre-hospital delay, thrombolysis, and quality of acute stroke care in a single document. The public's knowledge of stroke definition, risk factors, warning signs, and act on stroke generally remains low. According to studies using open-ended questions, the correct definition of stroke was recognized in less than 50%, hypertension as a stroke risk factor in less than 50%, and other well-defined risk factors in less than 20%. Among stroke warning signs, sudden paresis or numbness was best appreciated, with recognition rates ranging in 36.9-73.7%, but other warning signs including speech disturbance were underappreciated. In addition, less than one third of subjects in a representative population survey were aware of thrombolysis and had knowledge of the appropriate act on stroke, calling emergency medical services (EMS). Despite EMS being an essential element in the stroke chain of survival and outcome improvement, EMS protocols for field stroke diagnosis and prehospital notification for potential stroke patients are not well established. According to the Assessment for Quality of Acute Stroke Care, the median onset-to-door time for patients arriving at the emergency room was 4 hours (mean, 17.3 hours) in 2010, which was not reduced compared to 2005. In contrast, the median door-to-needle time for intravenous tissue plasminogen activator (IV-TPA) treatment was 55.5 minutes (mean, 79.5 minutes) in 2010, shorter than the median time of 60.0 minutes (mean, 102.8 minutes) in 2008. Of patients with acute ischemic stroke, 7.9% were treated with IV-TPA in 2010, an increase from the 4.6% in 2005. Particularly, IV-TPA use for eligible patients substantially increased, from 21.7% in 2005 to 74.0% in 2010. The proportion of hospitals equipped with a stroke unit has increased from 1.1% in 2005 to 19.4% in 2010. Performance, as measured by quality indicators, has steadily improved since 2005, and the performance rates for most indicators were greater than 90% in 2010 except for early rehabilitation consideration (89.4%) and IV-TPA use for eligible patients (74.0%). In summary, the current report indicates a substantial improvement in in-hospital acute stroke care, but also emphasizes the need for enhancing public awareness and integrating the prehospital EMS system into acute stroke management. This report would be a valuable resource for understanding the current status and implementing initiatives to further improve public awareness of stroke and acute stroke care in Korea.

Reliability and validity of prehospital case finding for depression and cognitive impairment.

To evaluate the test-retest reliability, the concurrent criterion validity, and the construct validity of prehospital, emergency medical service (EMS) case finding for depression and cognitive impairment in older adults. Cross-sectional study. Prehospital EMS system and hospital emergency department. EMS providers and community-dwelling older adult (aged > or =60) patients. Case finding instruments for depression (Patient Health Questionnaire-2; PHQ-2) and cognitive impairment (Six-Item Screener). The reliability and validity of these instruments. Moderate test-retest reliability was found for prehospital application of the PHQ-2 (kappa=0.50) and Six-Item Screener (kappa=0.52), fair concurrent criterion validity for depression (kappa=0.36), and slight to fair concurrent criterion validity for cognitive impairment (kappa=0.11-0.23). Construct validity was demonstrated using the Multitrait-Multimethod Matrix. Moderate test-retest reliability and construct validity were demonstrated for prehospital case finding by EMS providers for cognitive impairment and depression using these instruments. Slight to fair concurrent criterion validity was found, a result that methodological limitations could explain. These findings provide additional support for the concept of using EMS providers to detect older adults at risk for these conditions. Further work is needed to confirm the validity and effectiveness of prehospital screening before such programs are implemented.

Should anaesthetists be involved in prehospital care?

Across the world, there are basically two types of prehospital emergency medical service systems. In Anglo-American countries, acute out-of-hospital care for critically ill patients is provided by paramedics, while in most European countries, this role is filled by anaesthetists or emergency specialists. Intuitively, prehospital anaesthetists seem to be a useful adjunct for improved patient outcome but at greater expense. Which system provides the best medical care for critically ill patients in the prehospital setting? Is it purely an economic issue?

Emergency medical service attitudes toward geriatric prehospital care and continuing medical education in geriatrics.

To understand the opinions of emergency medical service (EMS) providers regarding their ability to care for older adults, the domains of geriatric medicine in which they need more training, and the modality through which continuing education could be best delivered. Qualitative study using key informant interviews. Prehospital EMS system in Rochester, New York. EMS providers, EMS instructors and administrators, emergency physicians, and geriatricians. Semistructured interviews were conducted using an interview guide that addressed knowledge and skill deficiencies, recommendations for improvement of geriatrics continuing education, and delivery methods of education. Participant responses were generally congruous despite the diverse backgrounds, and redundancy was achieved rapidly. All participants perceived a deficit in EMS education on the care of older adults, particularly related to communications with patients and skilled nursing facility staff. All desired more geriatric continuing education for EMS providers, especially in communications and psychosocial issues. Education was desired in various modalities. Further geriatric continuing education for EMS providers is needed. Some specific topics relate to medical issues, but a large proportion involve communications and psychosocial issues. Education should be delivered in a variety of modalities to meet the needs of the EMS community. Emerging on-line video technologies may bridge the gap between learners preferring classroom-based modailities and those preferring self-study modules.

The Prehospital Emergency Care System in Mexico City: A System's Performance Evaluation

Mexico City has one of the highest mortality rates in Mexico, with non-intentional injuries as a leading cause of death among persons 1-44 years of age. Emergency medical services (EMS) in Mexico can achieve high levels of efficiency by offering high quality medical care at a low cost through adequate system design. The objective of this study was to determine whether the prehospital EMS system in Mexico City meets the criteria standards established by the American Ambulance Association Guide for Contracting Emergency Medical Services (AAA Guide) for highly efficient EMS systems. This retrospective, descriptive study, evaluated the structure of Mexico City's EMS system and analyzed EMS response times, clinical capacity, economic efficiency, and customer satisfaction. These results were compared with the AAA guide, according to the soc ial, economic, and political context in Mexico. This paper describes the healthcare system structure in Mexico, followed by a description of the basic structure of EMS in Mexico City, and of each tenet described in the AAA guide. The p aper includesdata obtained from official documents and databases of government agencies, and operative and administrative data from public and private EMS providers. The quality of the data for response times (RT) were insufficient and widely varied among providers, with a minimum RT of 6.79 minutes (min) and a maximum RT of 61 min. Providers did not define RT clearly, and measured it with averages, which can hide potentially poor performance practices. Training institutions are not required to follow a standardized curriculum. Certifications are the responsibility of the individual training centers and have no government regulation. There was no evidence of active medical control involvement in direct patient care, and providers did not report that quality assurance programs were in place. There also are limited career advancement opportunities for EMS personnel. Small economies of scale may not allow providers to be economically efficient, unit hours are difficult to calculate, and few economic data are available. There is no evidence of customer satisfaction data. Emergency medical services in Mexico City did not meet the AAA requirements for high-quality, prehospital, emergency care. Coordination among EMS providers is difficult to achieve, due, in part, to the lack of: (1) an authoritative structure; (2) sound system design; and (3) appropriate legislation. The government, EMS providers, stakeholders, and community members should work together to build a high quality EMS system at the lowest possible cost.

Treatment of Suspected Cardiac Ischemia with Aspirin by Paramedics in an Urban Emergency Medical Services System

Background. Aspirin (ASA) has unquestioned benefit to patients with cardiac ischemia. Previous studies indicate health care providers may not adequately treat patients experiencing cardiac ischemia with ASA. Objective. To determine the rate of ASA use for patients being treated for chest pain suggestive of cardiac ischemia in the prehospital setting. Methods. This was a retrospective study of paramedic encounters identified through billing records for all patients receiving the combination of an intravenous catheter, supplemental oxygen, andcardiac monitoring from November 2001 to January 2002. Prehospital medical records were reviewed in order to determine the proportion of patients with suspected cardiac ischemia who received ASA. The setting was a single prehospital emergency medical services system serving an urban population. Results. A total of 2,457 paramedic encounters were reviewed over a three-month period. Two hundred thirty-two patients were assessed as having cardiac ischemia, of whom 169 (73%) had no absolute or relative contraindication to ASA. Of the 169 patients, only 92 (54%) received ASA. Of the 99 patients, who received nitroglycerin for presumed cardiac ischemia andhad no contraindication to receiving ASA, only 78 (79%) received ASA. Of the 453 patients complaining of nontraumatic chest pain andwithout a contraindication, 157 (35%) received ASA. Conclusions. Paramedics do not use ASA optimally andmay choose therapies with less proven benefit.
