Introduction. Pain and its control have been studied extensively in the emergency department. Numerous studies indicate that inadequate treatment of pain is common, despite the availability of myriad analgesics. It has been suggested that oligoanesthesia is also a common practice in the prehospital setting. Objective. To assess the use of prehospital analgesia in patients with suspected extremity fracture. Methods. Emergency medical services (EMS) call reports were reviewed for all patients with suspected extremity fractures treated from June 1997 to July 1998 in a midwestern community with a population base of 223,000. Data collected included demographic information, mechanism of injury, medications given, and field treatment. Standing orders for administration of analgesia were available and permitted paramedics to give either morphine sulfate or nitrous oxide per protocol. Results. The EMS call reports were analyzed for 1,073 patients with suspected extremity fractures. The mean patient age was 47 years. Accidental injuries comprised 86.5% of those reviewed. Suspected leg fractures were most common (20%), followed by hips (18%), arms (11%), knees (10%), ankles (9%), shoulders (7.2%), hands (5.5%), and wrists (5.3%). Multiple trauma and assorted broken digits accounted for the remaining 14%. The most common mechanisms of injury were: fall (43%), motor vehicle collision (21%), and human assault (10%). Intravenous lines were placed in 9.4% of patients; 17% received ice packs; 16% received bandage/dressings; 25% received air splints; and 19% were fully immobilized. Analgesia was administered to 18 patients (1.8%): 16 patients received nitrous oxide and two received morphine. Conclusion. Administration of analgesics to prehospital patients with suspected fractures was rare. Prehospital identification and treatment of pain for patients with musculoskeletal trauma could be improved. 相似文献

Objective: Recent American Heart Association guidelines suggest amiodarone as an antiarrhythmic in refractory ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT). The authors sought to assess the impact of amiodarone use on outcomes and cost associated with this practice in a rural emergency medical services (EMS) state. Methods: Statewide EMS records were reviewed for the calendar year 1999. Data reviewed included prehospital diagnosis, medications given by prehospital providers to patients with cardiac arrest, and procedures performed, including cardiopulmonary resuscitation (CPR) and defibrillation. Cost-benefit analysis assumed the cost of amiodarone treatment to be $137.65 per patient encounter. Absolute risk reduction (ARR) and number needed to treat (NNT) analysis utilized resuscitation rates published in the ARREST and ALIVE trials. Results: During the study period, EMS providers diagnosed 2,189 patients as having cardiac arrest. Five hundred thirty-five (24.4%) cardiac arrest patients were defibrillated. One hundred sixty patients (7.3%), including 15 who did not receive defibrillation, were given lidocaine during resuscitation efforts. The annual cost increase from current practice for a statewide amiodarone VF/VT protocol was $21,822.40 (10,572.87%). The initial cost to stock EMS vehicles for this protocol would be $50,115.52. The cost-benefit analysis yielded a potential for one additional patient survival to hospital discharge in Maine per 3.125 years of system-wide practice at a cost of $68,840.00. Conclusion: Based on current data, instituting amiodarone treatment for refractory VF and pulseless VT in a rural EMS setting requires the investment of substantial resources, relative to current treatment strategies, for any potential survival benefit. 相似文献

This report examines the literature regarding pneumococcal disease and the current state of pneumococcal vaccination. Improvements in medical care have reduced the number of deaths from pneumococcal disease. However, vaccination is still the most effective measure. The U.S. Department of Health and Human Services, through the Healthy People 2000 and Healthy People 2010 reports, have recommended widespread pneumococcal vaccination practices. In spite of this, vaccination rates remain low among all segments of the population, with minorities and groups at risk for pneumococcal disease the most neglected. The authors propose implementation of emergency medical services (EMS)-delivered vaccination against pneumococcal disease. The epidemiology of pneumococcal disease is presented. The efficacy, availability, and use recommendations for the vaccine are described within this report. Finally, the benefits and possible implementation strategies for EMS delivery are detailed. 相似文献

Advances in communication technologies are changing the face of emergency medical services (EMS). Two communication technologies in particular—cellular-enhanced 9-1-1 service and automatic crash notification (ACN)—will have a considerable impact on EMS. Although enhanced 9-1-1 service from land-line phones is now available in nearly every EMS system across the country, enhanced 9-1-1 service from cell phones currently does not exist. With more and more emergency calls made from cell phones, the implementation of this service is a clear priority. Automatic crash notification, a quickly emerging technology, can potentially provide EMS systems with invaluable data within seconds of when a collision occurs. However, many issues with regard to ACN systems need to be addressed, including liability concerns, access to ACN data, ability of drivers to understand the ACN system, and ACN system architecture. The potential interfaces between ACN systems and EMS systems create significant opportunities to enhance EMS resource management and care of patients involved in motor vehicle crashes. With both cellular-enhanced 9-1-1 and ACN in their infancy, EMS physicians and administrators have a valuable opportunity to provide leadership in the development of these services. 相似文献

Since the early 1970s, various publications and legislation have contributed to the development of emergency medical services (EMS) information systems and databases. Yet, even today, EMS systems vary in their ability to collect patient and systems data and to put these data to use. In addition, no means currently exists to easily link disparate EMS databases to allow analysis at local, state, and national levels. For this reason, the National Association of State EMS Directors is working with its federal partners at the National Highway Traffic Safety Administration (NHTSA) and the Trauma and EMS program of the Health Resources and Services Administration's (HRSA's) Maternal and Child Health Bureau to develop a national EMS database. Such a database would be useful in developing nationwide EMS training curricula, evaluating patient and EMS system outcomes, facilitating research efforts, determining national fee schedules and reimbursement rates, and providing valuable information on other issues related to EMS care. 相似文献

Objectives. The study was conducted to understand the prehospital system in Karachi, the mode of transport that adult inpatients use to reach the emergency departments (EDs), and the barriers to the use of ambulances. Methods. The study consisted of two parts. The first part involved interviewing the administrators of major ambulance services in Karachi. The second part consisted of a structured interview of randomly selected adult inpatients admitted to one government and one private hospital. Results. Seven ambulance service administrators were interviewed. The interviews revealed that ambulances in Karachi are mainly involved in transporting patients from hospital to hospital or to home. A large number of calls are for transporting dead bodies. A total of 92 patients were interviewed (58 male, 34 female). Admission complaints included abdominal pain (22), blunt trauma (11), penetrating trauma (3), chest pain (6), shortness of breath (4), hematemesis (3), acute focal weakness (4), high fever (4), and other (32). The most common mode of transport to the ED was taxi (53, 58%), followed by private car (21, 23%). Specific reasons for not using ambulances included a perception that the patient was not sick enough (34, 45%), slow response of the ambulance services (17, 23%), not knowing how to find one (8, 11%), and the high cost (6, 8%). Conclusion. In case of a medical emergency, most people in Karachi do not use ambulances. The reasons for this low usage include not only poor accessibility, but also cultural barriers and lack of education in recognition of danger signs. 相似文献

Objective: The emergency department (ED) is ideally reserved for urgent health needs. The ED, however, is often the site of care for nonurgent conditions. The authors investigated whether emergency medical technicians could decrease ED use by patients with nonurgent concerns who use 911 by appropriately identifying and triaging them to alternate care destinations. Methods: From August 2000 through January 2001, two King County fire-based emergency medical services (EMS) agencies participated in an alternate care destination program for patients with specific low-acuity diagnosis codes (intervention group). Eligible patients were offered care at a clinic-based destination as an alternate to the ED (n = 1,016). The frequency of the destination of care (ED, clinic, or home) for the intervention group was compared with a matched control group that was comprised of a preintervention historical cohort of EMS encounters from the same two fire-based agencies and with the same acuity and diagnosis criteria and seasonal interval (n = 2,617). Results: Compared with the preintervention group, a smaller proportion of patients in the intervention group received care in the ED (44.6% vs. 51.8%, p = 0.001), while a greater proportion of patients in the intervention group received clinic care (8.0% vs. 4.5%, p = 0.001) or home care (no transport) (47.4 vs. 43.7%, p = 0.043). Results were comparable when adjusted for other patient characteristics. Similar relationships were not evident among nonparticipating King County EMS agencies. Based on physician review and patient interview, the alternate care intervention appeared to be safe and satisfactory. Conclusion: An EMS-based program may represent one approach to limiting nonurgent ED use. 相似文献

The proposed Medicare fee schedule for medically necessary ambulance transportation will have a profound impact on emergency medical services (EMS) systems throughout the country. When the new Medicare rules are implemented, reimbursement for Medicare patients will be largely based on national relative value units that vary depending on the level of service provided, from basic life support to advanced life support emergency. Under the new fee schedule, nearly all EMS systems will lose money when compared with the actual cost of providing the service, particularly advanced life support services, rural services, efficient systems, and those that bill for services. To adapt to these impending changes, EMS administrators and medical directors must work together to diversify and solidify their revenue sources and to seek out ways to make their systems even more efficient while maintaining a high quality of clinical care. 相似文献

Emergency medical services for children, or EMSC, is still a relatively underdeveloped component of most state and local EMS systems. Advocacy and funding for EMSC from the federal EMSC Program, availability of many useful EMSC products, and the rapidly enlarging literature in EMSC have created heightened awareness and interest in improving systems for pediatric emergency, trauma, and critical care. The new National Highway Traffic Safety Administration (NHTSA) EMS Technical Assistance (TA) re-assessment program, the second version of the successful original TA Program from 1988 to 1996, provides an ideal opportunity for state EMS professionals to evaluate EMSC capabilities and to integrate new EMSC products and services. The history of the TA Program reflects the evolution of EMS itself and indicates a historical inattention to children's issues, but re-assessment TA teams now have much useful intervening EMSC history to draw upon and a clear philosophical mandate to integrate children more fully in EMS system planning and management. In order to facilitate state-of-the-art reviews of EMSC within state EMS systems, a pediatric survey for the NHTSA re-assessments is presented. The survey, developed with the input of EMS administrators and physicians and approved by the National Association of State EMS Directors, follows the original ten-component model for EMS system review. It is intended for optional use within the overall EMS review process. 相似文献

Objective. To determine predicted utilization, decrease in ambulance transports, and target population for emergency medical services (EMS) if telemedicine capabilities were available to the medic units in the field. Methods. A retrospective chart review of 345 consecutive ambulance transports to four hospitals (Level I urban trauma center, urban tertiary care center, children's hospital, and suburban community hospital) was performed by a panel of three board-certified emergency medicine physicians experienced and credentialed in emergency telemedicine. They independently reviewed the emergency department (ED) and EMS records and were asked to determine whether patients required ambulance transport for evaluation or whether disposition could be made following paramedic and emergency physician assessment via telemedicine. A five-point Likert scale was used to grade feasibility of telemedicine disposition (definitely yes, probably yes, maybe, probably no, definitely no). Other variables analyzed included age, sex, race, chief complaint, phone, private medical doctor, and call location by patient zip code, call site, and receiving hospital. Results. In 14.7% of cases (6% definitely yes and 8.7% probably yes), disposition could be made without transport using telemedicine. The age range for eliminating transport was 2 weeks through 92 years, with mean age of 26.6 years. Under the age of 50 years, 46 out of 238 patients (19.3%) could have possibly been managed by telemedicine. Conclusion. Use of EMS telemedicine could result in an approximately 15% decrease in ambulance transports when it alone is added to the prehospital care provider's armamentarium. Emphasis for implementation should be placed on younger patients and an identified subset of chief complaints conducive to management using telemedicine. 相似文献

While helicopter emergency medical services (HEMS) has its roots in military transport of wounded soldiers, rotor-wing transport is also used for a wide variety of nontrauma indications. Despite this common use of HEMS for noninjured patients, a Medline search found little systematic review of the literature pertinent to HEMS use for nontrauma. With HEMS utilization subject to appropriately increased scrutiny, those seeking to research HEMS utility in noninjured patients could benefit from existence of a collection of the topical literature. This paper aims to provide such a review, in the form of an annotated bibliography of Index Medicus journal studies assessing potential medical risks and benefits of HEMS transport for noninjured patients. The paper's goal is to provide a useful resource for those interested in pursuing more focused review of various sectors of the nontrauma HEMS literature. As such, the main objective of the article summaries is to provide a brief outline of study design and results; there is also limited editorial comment included after each summary. 相似文献

Objective. This study describes emergency medical services (EMS) responses for children with special health care needs (CSHCN) in an urban area over a one-year period. Methods. A prospective surveillance system was established to identify EMS responses for children, 21 years of age or younger, with a congenital or acquired condition or a chronic physical or mental illness. Responses related to the special health care needs of the child were compared with unrelated responses. Results. During a one-year period, 924 responses were identified. Fewer than half of the responses were related to the child's special health care need. Younger children were significantly more likely to have a response related to their special needs than older children. Among related responses, seizure disorder was the most common diagnosis, while asthma was more common for unrelated responses. Almost 58% of the responses resulted in transport of the child to a hospital. Conclusions. Emergency medical services responses related to a child's special health care needs differ from unrelated responses. The most common special health care needs of children did not require treatment beyond the prehospital care provider's usual standard of care. These results are relevant for communities providing EMS services for CSHCN. 相似文献

AbstractBackground. Thermal protective clothing (TPC) worn by firefighters provides considerable protection from the external environment during structural fire suppression. However, TPC is associated with physiologic derangements that may have adverse cardiovascular consequences. These derangements should be treated during on-scene rehabilitation periods. Objective. To examine heart rate and core temperature responses during the application of four active cooling devices, currently being marketed to the fire service for on-scene rehabilitation, and compare them with passive cooling in a moderate temperature (approximately 24°C) and with an infusion of cold (4°C) saline. Methods. Subjects exercised while they were wearing TPC in a heated room. Following an initial exercise period (bout 1), the subjects exited the room, removed the TPC, and for 20 minutes cooled passively at room temperature, received an infusion of cold normal saline, or were cooled by one of four devices (fan, forearm immersion in water, hand cooling, or water-perfused cooling vest). After cooling, the subjects donned the TPC and entered the heated room for another 50-minute exercise period (bout 2). Results. The subjects were not able to fully recover core temperature during a 20-minute rehabilitation period when provided rehydration and the opportunity to completely remove the TPC. Exercise durations were shorter during bout 2 when compared with bout 1 but did not differ by cooling intervention. The overall magnitudes and rates of cooling and heart rate recovery did not differ by intervention. Conclusions. No clear advantage was identified when active cooling devices and cold intravenous saline were compared with passive cooling in a moderate temperature after treadmill exercise in TPC. 相似文献

Objective. Prior emergency department (ED) and inpatient studies have found that women with coronary artery disease are more frequently misdiagnosed and undertreated compared with men. This study was performed to determine whether there is a gender bias in the prehospital management of patients with acute chest pain. Methods. This study was performed in a large urban county emergency medical services (EMS) agency with approximately 40,000 patient contacts/year. The study population comprised consecutive patients ≥45 years old with a chief complaint of atraumatic chest pain. Using χ2 analysis and the unpaired Student's t-test, male and female patient encounters were compared. This study had >80% power (alpha 0.05) to detect a 3% difference between populations. Results. Data from 2,858 consecutive patient encounters were analyzed, with females comprising 1,508 (53%). Females were significantly older than males (67 ± 13.1 vs. 62.7 ± 12.3 years, p < 0.001). Male patients were more likely to receive aspirin (42.3% vs. 35.4%, p < 0.001) and 12-lead electrocardiograms (ECGs) (46.8% vs. 39.3%, p < 0.001) compared with female patients. The rates of transport refusal, oxygen, nitroglycerin, and narcotic administration did not differ between populations. Conclusion. Although females presenting to this urban EMS system with acute chest pain were older, they received significantly less aspirin and fewer 12-lead ECGs in the field. These results suggest strategies must be developed to ensure that appropriate therapy is provided to women presenting to EMS systems with acute cardiac ischemia. 相似文献

The interval from collapse to electrical rescue shock is a critical determinant of successful defibrillation in cardiac arrest. In order to achieve the earliest possible defibrillation, many emergency medical services (EMS) systems equip first-responding units with an automated external defibrillator (AED). Objective. To measure the time from on-scene emergency medical technician (EMT) recognition of cardiac arrest to AED application and shock in ventricular fibrillation (VF) arrest. In addition, the authors sought to understand the reasons for delays. Methods. Using the AED recordings and written EMS reports, the authors conducted a retrospective cohort study of all persons who experienced an EMS-attended VF cardiac arrest in which an AED was applied and a shock delivered by an EMT, from January 1999 through December 2000 (n = 177). Based on the bimodal distribution of times, two groups were assembled: no delay (time to shock ≤ 90 seconds) and delayed (time to shock > 90 seconds). Patient and event characteristics associated with delay status were determined using Mantel-Haenszel methods. Results. The median (25th, 75th percentile) time from cardiac arrest recognition to shock was 51 (43, 64) seconds. Ninety-four percent (n = 166) of the cohort received a shock within 90 seconds. Delayed shock was associated with unwitnessed arrest status (odds ratio = 9.3, 95% confidence interval = 2.3, 36.8) and nursing home location (odds ratio = 10.0, 95% confidence interval = 2.1, 47.5). Conclusion. The findings suggest that a 1-minute goal and a 90-second minimum standard for time to first shock are appropriate for EMT AED defibrillation in the field. 相似文献

In December 1999, a group of emergency physicians from the United States, Israel, and Ethiopia met for the Second Annual Symposium on Emergency Medicine and to perform an initial evaluation of the prehospital care system in Addis Ababa. The symposium was structured into a workshop on prehospital care and a clinical seminar for emergency medicine providers. This article describes the current prehospital infrastructure in Addis Ababa, Ethiopia. This serves as the basis for more specific needs assessments and training interventions, which are ongoing. The authors present a list of priorities for the development of an emergency medical services (EMS) system for Addis Ababa that was generated in partnership with local government and the World Health Organization. The article contrasts these initial recommendations with those found in the literature on the development of EMS systems in developing nations. 相似文献
