PURPOSE: This study explored the factors influencing disaster response competency, that is, demographic and disaster-related characteristics, personal disaster (household and workplace) preparedness, disaster risk perception, and self-efficacy in handling disasters among emergency medical technicians in South Korea.METHODS: The study follows a descriptive, cross-sectional design and uses a self-reported questionnaire. Emergency medical technicians, amounting to 1,020 in all, currently working in firefighting organizations from four South Korean cities (Busan, Daegu, Daejeon, and Ulsan) participated in the study.RESULTS: Disaster risk perception, self-efficacy for disaster, participation experience in disaster education/training, and personal disaster (household and workplace) preparedness predicted the disaster response competency of emergency medical technicians in South Korea.CONCLUSION: There is a need for an antidisaster program to enhance the disaster risk perception, self-efficacy, personal disaster (household and workplace) preparedness, and the disaster education/training participation rate toward enhancing disaster response competency of emergency medical technicians in South Korea.

Pre-hospital i-gel blind intubation for trauma: a simulation study

OBJECTIVE: This study aimed to evaluate the efficacy of i-gel blind intubation (IGI) as a rescue device for definitive airway management in ground intubation for pre-hospital trauma patients. METHODS: A prospective randomized crossover study was conducted with 18 paramedics to examine intubation performance of two blind intubation techniques through a supraglottic airway devices (IGI and laryngeal mask airway Fastrach), compared with use of a Macintosh laryngoscope (MCL). Each intubation was conducted at two levels of patient positions (ground- and stretcher-level). Primary outcomes were the intubation time and the success rate for intubation. RESULTS: The intubation time (sec) of each intubation technique was not significantly different between the two positions. In both patient positions, the intubation time of IGI was shortest among the three intubation techniques (17.9±5.2 at the ground-level and 16.9±3.8 at the stretcher-level). In the analysis of cumulative success rate and intubation time, IGI was the fastest to reach 100% success among the three intubation techniques regardless of patient position (all P < 0.017). The success of intubation was only affected by the intubation technique, and IGI achieved more success than MCL (odds ratio, 3.6; 95% confidence interval, 1.1 to 11.6; P=0.03). CONCLUSION: The patient position did not affect intubation performance. Additionally, the intubation time with blind intubation through supraglottic airway devices, especially with IGI, was significantly shorter than that with MCL.

The effect of hospital based clinical practice of paramedic students on cardiopulmonary resuscitation performance and recognition: a before and after study

OBJECTIVE: Various educational programs have been implemented to achieve skill, willingness and self-confidence in performing cardiopulmonary resuscitation (CPR). Paramedic students usually participate in clinical practice in emergency department as one of their educational courses. We investigated the effects of hospital based clinical practice and participation in real cardiac arrest situation on paramedic students' CPR performance and recognition. METHODS: Eighty-one paramedic students from 10 different universities who received hospital based clinical practice for 3 or 4 weeks in a regional emergency medical center from December 2016 to August 2017 were enrolled in our study. Subjects were asked, using a questionnaire, about their confidence and willingness to perform CPR before and after clinical practice. We also objectively measured two minute-CPR performance using the Laerdal skill reporter before and after clinical practice. During clinical practice, students participated in real CPR situations and took several theoretical examinations; however, additional CPR practical training was not included. RESULTS: This study included 48.1% male volunteers and 70.4% respondents who had Basic Life Support provider certification. The average number of real CPR situations participated in was 8.35 times. Scores in confidence of CPR increased significantly (3.80 vs. 4.36, P < 0.001) after clinical practice; however, scores in willingness to conduct CPR were high in both groups (4.46 vs. 4.48, P=0.787). Average chest compression depth also increased significantly (51.3 mm vs. 55.5 mm, P < 0.001) after clinical practice, but average compression rate showed no difference (111 vs. 111, P=0.694). Correct hand positioning and chest recoil also showed no difference between groups. CONCLUSION: Hospital based clinical practice of paramedic students could provide extra confidence in student's ability to perform CPR and lead to adequate chest compression depth.

The relationship of examinees' individual characteristics and perceived acceptability of smart device-based testing to test scores on the practice test of the Korea Emergency Medicine Technician Licensing Examination / 보건의료교육평가

PURPOSE: Smart device-based testing (SBT) is being introduced into the Republic of Korea’s high-stakes examination system, starting with the Korean Emergency Medicine Technician Licensing Examination (KEMTLE) in December 2017. In order to minimize the effects of variation in examinees’ environment on test scores, this study aimed to identify any associations of variables related to examinees’ individual characteristics and their perceived acceptability of SBT with their SBT practice test scores. METHODS: Of the 569 candidate students who took the KEMTLE on September 12, 2015, 560 responded to a survey questionnaire on the acceptability of SBT after the examination. The questionnaire addressed 8 individual characteristics and contained 2 satisfaction, 9 convenience, and 9 preference items. A comparative analysis according to individual variables was performed. Furthermore, a generalized linear model (GLM) analysis was conducted to identify the effects of individual characteristics and perceived acceptability of SBT on test scores. RESULTS: Among those who preferred SBT over paper-and-pencil testing, test scores were higher for male participants (mean± standard deviation [SD], 4.36± 0.72) than for female participants (mean± SD, 4.21± 0.73). According to the GLM, no variables evaluated— including gender and experience with computer-based testing, SBT, or using a tablet PC—showed a statistically significant relationship with the total score, scores on multimedia items, or scores on text items. CONCLUSION: Individual characteristics and perceived acceptability of SBT did not affect the SBT practice test scores of emergency medicine technician students in Korea. It should be possible to adopt SBT for the KEMTLE without interference from the variables examined in this study.

Association of Violent Experience and Resilience with Burnout in Emergency Medical Technicians / 한국직업건강간호학회지

PURPOSE: This descriptive correlational study investigated the effects of violent experience and resilience on burnout in emergency medical technicians (EMTs). METHODS: The participants were 160 EMTs working in fire stations (safety center and local center) located in U, B, and D city. The collected data were analyzed by descriptive statistics, independent t-test, ANOVA, Scheffé test post-hoc analysis, Pearson correlation coefficients, and multiple regression analysis using IBM SPSS Statistics 20.0. RESULTS: The number of EMTs getting into ambulances was significantly associated with violent experience, resilience, and burnout. Position of EMTs was significantly associated with both resilience and burnout. In the multiple regression analysis, the subscales of durability and optimism in resilience were significantly associated with burnout after controlling for confounding variables. CONCLUSION: This study indicated that improving durability and optimism in resilience was important to cope with experience of violence and to prevent burnout in EMTs.

Comparison of Outcomes between AutoPulse(TM) and Manual Compression in Out-of-hospital Cardiac Arrest Patient

PURPOSE: This study compared the outcomes of AutoPulseTM compression with manual compression provided by 119 paramedics in out-of-hospital cardiac arrest patients. METHODS: Between March and December 2016, a total of 221 out-of-hospital cardiac arrest patients were included for analysis. The patients included were categorized as the AutoPulseTM compression group and manual compression group. Patient's age, sex, pre-hospital intubation, bystander cardiopulmonary resuscitation (CPR), initial cardiac rhythm, time from arrest to CPR and CPR duration were reviewed retrospectively. The initial pH, lactate level, white blood cell (WBC) count, delta neutrophil index (DNI), and targeted temperature management status were collected. As clinical outcomes, the return of spontaneous circulation (ROSC), hospital and intensive care unit (ICU) length of stay, survival rate, and cerebral performance category (CPC) scale at discharge were analyzed. RESULTS: The initial rhythm and CPR duration were similar in the two groups. On the other hand, the pre-hospital intubation rate and pre-hospital CPR duration were significantly higher in the AutoPulseTM group than the manual group (32.9% vs. 12.7%, p < 0.001; 15.2 vs. 11.9 minutes, p=0.002). The ROSC rate, hospital and ICU length of stay, CPC scale and survival rate at discharge as the clinical outcome were similar in the AutoPulseTM group and manual group. The pH was lower and the lactate level was significantly higher in the AutoPulseTM group than the manual group (6.91 vs. 6.96, p=0.007; 12.8 vs. 11.4 mmol/L, p=0.031), but the WBC and DNI were similar in the two groups. CONCLUSION: The use of AutoPulseTM provided by 119 paramedics in out-of-hospital cardiac arrest patients is not associated with better clinical outcomes.

Overview and current management of computerized adaptive testing in licensing/certification examinations / 보건의료교육평가

Computerized adaptive testing (CAT) has been implemented in high-stakes examinations such as the National Council Licensure Examination-Registered Nurses in the United States since 1994. Subsequently, the National Registry of Emergency Medical Technicians in the United States adopted CAT for certifying emergency medical technicians in 2007. This was done with the goal of introducing the implementation of CAT for medical health licensing examinations. Most implementations of CAT are based on item response theory, which hypothesizes that both the examinee and items have their own characteristics that do not change. There are 5 steps for implementing CAT: first, determining whether the CAT approach is feasible for a given testing program; second, establishing an item bank; third, pretesting, calibrating, and linking item parameters via statistical analysis; fourth, determining the specification for the final CAT related to the 5 components of the CAT algorithm; and finally, deploying the final CAT after specifying all the necessary components. The 5 components of the CAT algorithm are as follows: item bank, starting item, item selection rule, scoring procedure, and termination criterion. CAT management includes content balancing, item analysis, item scoring, standard setting, practice analysis, and item bank updates. Remaining issues include the cost of constructing CAT platforms and deploying the computer technology required to build an item bank. In conclusion, in order to ensure more accurate estimations of examinees' ability, CAT may be a good option for national licensing examinations. Measurement theory can support its implementation for high-stakes examinations.

Varying levels of difficulty index of skills-test items randomly selected by examinees on the Korean emergency medical technician licensing examination / 보건의료교육평가

PURPOSE: The goal of this study was to characterize the difficulty index of the items in the skills test components of the class I and II Korean emergency medical technician licensing examination (KEMTLE), which requires examinees to select items randomly. METHODS: The results of 1,309 class I KEMTLE examinations and 1,801 class II KEMTLE examinations in 2013 were subjected to analysis. Items from the basic and advanced skills test sections of the KEMTLE were compared to determine whether some were significantly more difficult than others. RESULTS: In the class I KEMTLE, all 4 of the items on the basic skills test showed significant variation in difficulty index (P<0.01), as well as 4 of the 5 items on the advanced skills test (P<0.05). In the class II KEMTLE, 4 of the 5 items on the basic skills test showed significantly different difficulty index (P<0.01), as well as all 3 of the advanced skills test items (P<0.01). CONCLUSION: In the skills test components of the class I and II KEMTLE, the procedure in which examinees randomly select questions should be revised to require examinees to respond to a set of fixed items in order to improve the reliability of the national licensing examination.

Prevention and Decontamination of Chemical, Biological, Radiological, and Nuclear Contaminants for the Emergency Medical Personnel during Ambulance Services / 한양의대학술지

This paper will review proper protocol for Emergency Medical Technicians (EMTs) between the ambulance station, scene and hospital. EMTs must know how to protect themselves both inside and outside the ambulance from chemical, biological, radiological, and nuclear (CBRN) contaminants in order to provide the best quality care. EMTs should also know how to remove contamination after taking a patient to the hospital. A CBRN protocol at the scene of exposure is the best defense strategy for protecting both EMTs and the emergency ambulance vehicle from contamination. If EMTs and the emergency ambulance vehicle are exposed to CBRN, neither will be of great service as they both play a critical part in the quality of care given to a patient. In the event of possible exposure, EMTs should dress in high perceptibility personal protective equipment (PPE). Those who have been trained prior should arrive to the scene with an air purifying respirator. Before a patient with possible exposure is placed inside an emergency ambulance vehicle, all patients' compartments should be completely covered and sealed with plastic film. Once the emergency medical crew reaches the hospital and the patient is discharged from the emergency vehicle, all plastic film inside the ambulance, from the cockpit ceiling to the floor, should be removed and properly discarded. The patient's clothing and shoes should be placed into a double layered plastic bag. Adhering to proper protocols, within 10 minutes of arrival at hospital, a contaminated ambulance should undergo pre-washing, decontamination and rinsing operations.

Current Status of Infection Prevention and Control Programs for Emergency Medical Personnel in the Republic of Korea / 예방의학회지

OBJECTIVES: Emergency medical personnel (EMPs) are pre-hospital emergency responders who are at risk of exposure to infections and may also serve as a source for the transmission of infections. However, few studies of infection control have specifically addressed EMPs in the Republic of Korea (hereafter Korea). The goal of this study was to assess the current status of infection prevention and control programs (IPCPs) for EMPs in Korea. METHODS: A cross-sectional survey was conducted to quantitatively assess the resources and activities of IPCPs. A total of 907 EMPs in five metropolitan cities completed a structured questionnaire from September 2014 to January 2015. The data were analyzed using descriptive statistics, multi-response analysis, and the chi-square test. RESULTS: The mean age of the participants was 34.8+/-15.1 years. IPCPs were found to have weaknesses with regard to the following resources: the assignment of infection control personnel (ICP) (79.5%), hand hygiene resources such as waterless antiseptics (79.3%), the use of paper towels (38.9%), personal protective equipment such as face shields (46.9%), and safety containers for sharps and a separated space for the disposal of infectious waste (10.1%). Likewise, the following activities were found to be inadequately incorporated into the workflow of EMPs: education about infection control (77.5%), post-exposure management (35.9%), and the decontamination of items and spaces after use (88.4%). ICP were found to have a significant effect on the resources and activities of IPCPs (p<0.001). The resources and activities of IPCPs were found to be significantly different among the five cities (p<0.001). CONCLUSIONS: IPCPs for EMPs showed some limitations in their resources and activities. IPCPs should be actively supported, and specific IPCP activities for EMPs should be developed.

Necessity of Education for Emergency Medical Technicians to Improve Awareness of Early Symptoms of Stroke and Assessment of Stroke Patients / 農村醫學 地域保健

OBJECTIVES: The purpose of this study was to reconsider the necessity of stroke-related educational programs by investigating early symptoms of stroke that emergency medical technicians (EMTs) may experience. METHODS: An interview survey was carried out, targeting all EMTs 298 people who were working at 119 fire safety centers and local units in Jeollabuk-do province, from April 1 to 30, 2011. An interviewer administered questionnaire was used to obtain data on ETMs' demographic characteristics, educational level on stroke, and awareness level about early symptoms of stroke and treatment-related characteristics of stroke patients. RESULTS: The results showed that 63.2% of those surveyed had completed the required educational programs on stroke during the past year. The level of awareness about early symptoms of stroke and assessment of stroke patients' condition was relatively high for women, those who were 30 years under, low position people, emergency service practitioners, emergency medical technicians, and people who have completed education, respectively. It was also turned out that 82.8% of those surveyed took stroke patients to the nearest hospitals first so that they could receive appropriate treatment. The level of awareness about early symptoms of stroke and assessment of stroke patients' condition in people who have completed education were higher than non-complete. The level of awareness about early symptoms of stroke was positively correlated with confidence, satisfaction and appropriateness in treatment of stroke patients. CONCLUSIONS: These results strongly suggest that it is necessary to operate specialized educational programs to enhance EMTs' appropriate awareness of the early symptoms of stroke and assessment of stroke patient's condition.

Influence of Job Stress and State of Sleep on the Depression of Emergency Medical Technicians / 한국직업건강간호학회지

PURPOSE: The purpose of this study was to identify the relationship of job stress, state of sleep, and depression and to identify factors influencing depression of emergency medical technicians. METHODS: The research was a cross-sectional, descriptive study. Data collection were done using self-report questionnaires with 162 emergency medical technicians working in hospitals who agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression with the SPSS/WIN 18.0 Program. RESULTS: Depression had significant negative correlations with state of sleep, (r=-482, p<.001) and positive correlations with job stress (r=.196,p=.013). State of sleep had significant negative correlations with job stress (r=-.168, p=.033). The variance for life satisfaction was 23.7% (F=25.964, p<.001). Variable of state of sleep significantly predicted depression of emergency medical technicians. CONCLUSION: Considering these results, for emergency medical technicians' job stress, state of sleep, and depression, further studies are needed. Furthermore, there is a need to develop and implement new strategies to improve depression among emergency medical technicians.

Do mannequin chests provide an accurate representation of a human chest for simulated decompression of tension pneumothoraxes? / 世界急诊医学杂志（英文）

BACKGROUND: Tension pneumothorax (TPX) is an uncommon but life-threatening condition. It is important that this uncommon presentation, managed by needle decompression, is practised by paramedics using a range of educationally sound and realistic mannequins. The objective of this study is to identify if the chest wall thickness (CWT) of training mannequins used for chest decompression is an anatomically accurate representation of a human chest. METHODS: This is a two-part study. A review of the literature was conducted to identify chest wal thickness in humans and measurement of chest wal thickness on two commonly used mannequins. The literature search was conducted using the Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, and EMBASE databases from their beginning until the end of May 2012. Key words included chest wall thickness, tension pneumothorax, pneumothorax, thoracostomy, needle thoracostomy, decompression, and needle test. Studies were included if they reported chest wal thickness. RESULTS: For the literature review, 4461 articles were located with 9 meeting the inclusion criteria. Chest wall thickness in adults varied between 1.3 cm and 9.3 cm at the area of the second intercostal space mid clavicular line. The Laerdal? manikin in the area of the second intercostal space mid clavicular line, right side of the chest was 1.1 cm thick with the left 1.5 cm. The MPL manikin in the same area or on the right side of the chest was 1.4 cm thick but on the left 1.0 cm. CONCLUSION: Mannequin chests are not an accurate representation of the human chest when used for decompressing a tension pneumothorax and therefore may not provide a realistic experience.

Validation of the Pentax-AWS Airwayscope as a Prehospital Intubation Device by Korean Level 1 Emergency Medical Technicians; A Simulation Study Using an Airway Training Manikin

PURPOSE: Tracheal intubation in the pre-hospital setting may be lifesaving in severely ill and injured patients. The aim of the current study was to evaluate whether use of the video laryngoscope, when used by Korean level 1 emergency medical technicians, resulted in faster or more secure facilitation of tracheal intubation, compared with the conventional laryngoscope with the immobilized cervical spine lying on the ground. METHODS: Thirty two level 1 EMTs working as 119 rescuers performed tracheal intubation on a manikin using the Macintosh laryngoscope (McL) and the Pentax-AWS(R) airwayscope (AWS) "on-the-bed" and "on-the-ground" in simulations with or without cervical spine immobilization. We compared intubation time, dental injury, and visual analog scale for both types of laryngoscope. RESULTS: In the McL trial, four participants failed on the bed, and 11 failed on the ground with cervical immobilization. In the AWS trial, all participants successfully secured the airway regardless of cervical spine immobilization both on the bed and on the ground. With the AWS, intubation time was not lengthened due to cervical spine immobilization either on the bed or on the ground. The AWS score was better than the McL on the visual analog scale in ease of handling the laryngoscope both on the bed and on the ground. And use of the AWS resulted in the lowest number of dental compressions. CONCLUSION: We conclude that the AWS is an effective and safe device for use in pre-hospital intubation with cervical spine immobilization, not only on the bed but also on the ground, when used by Korean level 1 EMTs. However, conduct of further studies is required in order to validate the clinical relevance of these findings.

The Current State of Airway Management and Ventilation at the Pre-Hospital Stage by Emergency Medical Technicians

PURPOSE: Airway management and ventilation at the pre-hospital stage are essential and very critical to patient welfare. In Korea, however, methods other than the use of a bag valve mask are hardly used at the pre-hospital stage by emergency medical technicians (EMTs). This study survey the current state of airway management and respiratory first aid at the pre-hospital stage. METHODS: A questionnaire survey of 356 EMTs was conducted by distributing questionnaires directly to first-class EMTs who participated in clinical training at emergency centers or by sending questionnaires and receiving answers by E-mail. The questionnaire solicited information concerning general characteristics of EMTs, monthly frequency of pre-hospital airway management of patients and the will of EMTs. Subjects were divided into two groups according to governmental subdivision or presence of training within 1-year. RESULTS: Concerning airway management and ventilation at the pre-hospital stage, the use of methods other than nasal prong and simple mask was very rare. As to the reasons, the respondents mentioned the shortage of manpower and lack of knowledge/experience. There was no significant difference in the ratio of pre-hospital airway management between urban and suburban/rural settings. Training within 1-year was not related to increased enforcement of airway management. CONCLUSION: In Korea, pre-hospital airway management is not well implemented by EMTs. Causes are deficiency of rescuer, less actual patient treatment experience and deficiency of knowledge/experience. Education and work experience can influence pre-hospital airway management. But, most pre-hospital airway management is unaffected by education and work experience.

The Factors Influencing Empowerment of 119 Emergency Medical Technicians / 산업간호학회지

PURPOSE: The purpose of this study is to investigate the impact of job stress, self-efficacy and empowerment of 119 Emergency medical technicians in Jeollanam-do. METHODS: This study used the data collected from 346 respondents working for first aid in a fire station. To answer research questions, this study employed frequency analysis, reliability test, F (t)-test, ANOVA, Scheffe' post-hoc test, and multiple-regression analysis. RESULTS: In terms of demographic characteristics, marital status and age had significant impact on job stress, but sex and education did not. In terms of job characteristics, first placement, rank, and tenure made significant difference on job stress, whereas certificate, department, and area did not. These results address that general characteristics, self-efficacy and job stress are critical variables on empowerment. CONCLUSION: From the research findings, it is concluded that fire fighters' job stress can be reduced if professional development programs are given to them, which is likely to provide better public services such as first aids and welfare, as well as to increase job satisfaction.

The Knowledge and Attitude of Prehospital Care among Emergency Medical Technicians Working at 119 Fire Safety Centers for Patients with Acute Drug Intoxication / 農村醫學 地域保健

OBJECTIVES: The purpose of this research is to provide foundational data for reeducation concerning prehospital emergency care in order to improve the performance of emergency medical technicians (EMTs) working at 119 fire safety centers. METHODS: Data were collected using a mail-in questionnaire developed by researchers from 288 subjects, who were EMTs working at 119 fire safety centers and local units in the Gwangju Metropolitan City and South Jeolla Province, from March 1, 2009 to April 31, 2009. RESULTS: The mean score for EMTs' knowledge on drug intoxication was 7.04 out of a total of 10 points. The mean score for EMT's attitude of emergency treatment performance on drug intoxication was 2.96 out of a total of 4 points. The level of EMT's knowledge is relatively high regarding prehospital care for drug intoxication. The EMT's attitude of performances demonstrated an understanding of the patients' conditions. However EMTs did not actively explain the prognosis and medical conditions for their patients. CONCLUSIONS: This research will contribute to making plans for reeducating emergency crew working at 119 fire centers so that can they have a more active attitude towards prehospital emergency medical care.

Job Stress and Work-Related Musculoskeletal Symptoms of 119 Emergency Medical Technicians / 산업간호학회지

PURPOSE: This study was done to investigate the prevalence of job stress and musculoskeletal symptoms, and to identify the factors that affect work-related musculoskeletal symptoms of the 119 Emergency medical technicians (EMT). METHOD: From August 26 to September 10, 2010, the data were obtained from 456 EMT working in Daejeon city or Choongnam province. For data analysis, descriptive statistics and multiple logistic regression were performed using SAS version 9.1. RESULTS: Physical environment, job demand, interpersonal conflict, and occupational climate were stressful to 119 EMT. The prevalence of musculoskeletal symptoms of female EMT was higher than those of the male EMT's. After gender and age were adjusted, there ware significant relationships between musculoskeletal symptoms and some risk factors including occupational class, hours of intensive musculoskeletal use, previous injury or work-related injury, physical burden, and job stress. Overall, a higher degree of job stress increased musculoskeletal symptoms. CONCLUSION: Job stress is a major cause of musculoskeletal symptoms. To prevent and manage musculoskeletal disease of 119 EMT, there is a need to develop a management program for musculoskeletal symptoms to reduce occupational stress, considering gender differences.

What is the Appropriate Level of Electrocardiography Education Needed for Emergency Medical Technicians (EMT) Students?

PURPOSE: Assess the appropriate level of electrocardiography (EKG) education that should be incorporated into the curriculum of emergency medical technician (EMT) students. METHODS: Consensus by EMT professors and emergency medicine specialists was obtained using two rounds of the Delphi survey. The questionnaire consisted of 70 items; 12 related to demographic information, 8 related to general interpretation of EKG, 26 related to interpretation of arrhythmia, 20 related interpretations of structural anomaly, infarction and systemic disease, and 4 related to interpretation of EKG findings used for advanced cardiac life support. We considered consensus to be agreement of greater than 7 of 9 (66.7%). RESULTS: 59 and 24 subjects were included in the first and second rounds of the Delphi survey, respectively. The response rate was 59% for the first round and 40.7% for the second round. Of 70 items, 40 items came to a consensus by the panel. All items related to interpretation of EKG and advanced cardiac life support and most (10 of 12) items related to basic content were felt to be important by both EMT professors and emergency medicine specialists. However, for items related to arrhythmia and related to structural anomaly, infarction and systemic disease, less than half of the items examined were felt to be necessary in the curriculum of EMT students (12 of 26 and 6 of 20). CONCLUSION: We identified 40 items that should be included into the EKG curriculum of EMT students. These findings should be used to create more effective educational programs for EMT students.
