Mental Health Aspects of Emergency Medical Services for Children Summary of a Consensus Conference

OBJECTIVE: To address the mental health needs of children involved in emergency medical services (EMS). METHODS: A multidisciplinary consensus conference convened to identify mental health needs of children and their families related to pediatric medical emergencies, to examine the impact of psychological aspects of emergencies on recovery and satisfaction with care, and to delineate research questions related to mental health aspects of medical emergencies involving children. RESULTS: The consensus group found that psychological and behavioral factors affect physical as well as emotional recovery after medical emergencies. Children's reactions are critically affected by age and developmental level, characteristics of the emergency medical event, and parent reactions. As frontline health care providers, EMS staff members are in a pivotal position to recognize and effectively manage the mental health needs of patients and their families. CONCLUSIONS: Ecological changes in emergency departments, such as linkages to mental health follow-up services, training of EMS providers and mental health professionals, and focused research that provides an empirical basis for practice, are necessary components for improving current standards of health care.     

Pediatric Use of Emergency Medical Services: The Role of Chronic Illnesses and Behavioral Health Problems

Objective: The increasing use of prehospital emergency medical services (EMS) and its contribution to rising emergency department use and healthcare costs point to the need for better understanding factors associated with EMS use to inform preventive interventions. Understanding patient factors associated with pediatric use of EMS will inform pediatric-specific intervention. We examined pediatric patient demographic and health factors associated with one-time and repeat use of EMS. Methods: We reviewed data from Baltimore City Fire Department EMS patient records over a 23-month period (2008–10) for patients under 21 years of age (n = 24,760). Repeat use was defined as involvement in more than one EMS incident during the observation period. Analyses compared demographics of EMS users to the city population and demographics and health problems of repeat and one-time EMS users. Health comparisons were conducted at the patient and incident levels of analysis. Results: Repeat users (n = 1,931) accounted for 9.0% of pediatric users and 20.8% of pediatric incidents, and were over-represented among the 18–20 year age group and among females. While trauma accounted for approximately one-quarter of incidents, repeat versus one-time users had a lower proportion of trauma-related incidents (7.2% vs. 26.7%) and higher proportion of medical-related incidents (92.6% vs. 71.4%), including higher proportions of incidents related to asthma, seizures, and obstetric/gynecologic issues. In patient-level analysis, based on provider or patient reports, greater proportions of repeat compared to one-time users had asthma, behavioral health problems (mental, conduct and substance use problems), seizures, and diabetes. Conclusions: Chronic somatic conditions and behavioral health problems appear to contribute to a large proportion of the repeat pediatric use of this EMS system. Interventions may be needed to engage repeat users in primary care and behavioral health services, to train EMS providers on the recognition and management of behavioral health emergencies, and to improve family care and self-management of pediatric asthma and other chronic conditions.     

Meeting the challenge of bioterrorism: lessons learned from West Nile virus and anthrax

Hospital emergency departments (EDs) and ambulatory clinics may be the first to recognize illness related to a bioterrorist event. Every health-care institution must develop a weapons-of-mass- destruction (WMD) preparedness plan as part of its all-hazards disaster planning. As part of an all-hazards disaster plan, WMD preparedness should use the incident-command model to insure the required chain of command for effectively coordinating activities between hospital departments and external agencies. Preparedness for bioterrorism poses unique challenges. In the event of a biological attack, the hospital infection control staff and administration must already have in place the means to communicate with local and state public health agencies, the Centers for Disease Control and Prevention (CDC), local law-enforcement agencies, and the Federal Bureau of Investigation (FBI). Local and regional planners must consider how to coordinate the responses of emergency medical services (EMS), police, and fire departments with healthcare providers and the news media. Most hospitals are ill equipped to deal with a catastrophic event caused by WMD. The burden of responding to such events will fall initially on ED physicians and staff members. The severity of such an incident might be mitigated with careful planning, training and education. The responses of one hospital network to the outbreak of West Nile virus and, more recently, to the threat of anthrax, are presented as guides for bioterrorism preparedness.     

Inappropriate Use of Emergency Medical Services Transport: Comparison of Provider and Patient Perspectives

Objectives: To determine the extent of inappropriate ambulance use from the perspectives of both emergency medical services (EMS) providers and patients utilizing EMS transport, assess level of agreement, and identify variables associated with inappropriate ambulance use. Methods: A prospective cross-sectional study was done of a consecutive sample of patients arriving by ambulance during the month of February 1997 at an urban university hospital ED. EMS providers and patients completed a survey with questions regarding their perceptions of whether the need for ambulance transport was an emergency or a nonemergency. Patient demographic information and availability of alternate means of transportation to the hospital were also evaluated. Results: Eight hundred eighty-seven patients were included in the study. EMS providers thought that 501 patient transports were appropriate and represented true emergencies, whereas 689 patients believed their medical problems were true emergencies. A significant number of patients (n = 415, 47%) had access to alternative transportation to the hospital. Blunt traumatic injury and altered mental status were the most common reasons for EMS transport. Patient characteristics significantly associated with EMS provider perception of a true emergency were male gender, age >51 years, higher education, chest pain/cardiac complaints, shortness of breath/respiratory complaints, and Medicare insurance. Characteristics significantly associated with patients who perceived themselves to have true emergencies were black ethnicity, higher education, shortness of breath/respiratory complaints, and Medicare insurance. There was 75% agreement between EMS providers and patients on appropriateness of ambulance transport (kappa = 0.84). Conclusion: Inappropriate ambulance use is a significant problem from both EMS provider and patient perspectives. Certain patient characteristics are associated with a higher probability of appropriate and inappropriate uses of EMS transport. A large number of patients transported by ambulance have alternative means of transportation but elect not to use them.     

Development of emergency medical services in Guatemala

Guatemala has recently undergone many advances in emergency medical services (EMS) training and disaster management. Industrialization and demographic changes have led to a continuing decline in the prevalence of infectious disease, while trauma and cardiovascular-related deaths have become increasingly important. Trauma now accounts for the nation's single greatest cause of productive years of life lost, a major indicator of a disease's impact on society. This “demographic transition” has dramatically increased the number of incidents where early prehospital intervention can have a positive impact on morbidity and mortality. However, until recently, prehospital medical care was provided by firefighters, who lacked formal medical training. Responding to a perceived need, increased collaborative efforts between prehospital care providers and governmental and nongovernmental agencies have rapidly improved provider training, initiated care standardization, and improved disaster preparedness. These efforts may serve as a model to other developing nations seeking to improve their EMS systems.     

Emergency Medical Services Provider Experiences of Hospice Care

Background: Growing numbers of emergency medical services (EMS) providers respond to patients who receive hospice care. The objective of this investigation was to assess the knowledge, attitudes, and experiences of EMS providers in the care of patients enrolled in hospice care. Methods: We conducted a survey study of EMS providers regarding hospice care. We collected quantitative and qualitative data on EMS provider's knowledge, attitudes, and experiences in responding to the care needs of patients in hospice care. We used Chi-squared tests to compare EMS provider's responses by credential (Emergency Medical Technician [EMT] vs. Paramedic) and years of experience (0–5 vs. 5+). We conducted a thematic analysis to examine open-ended responses to qualitative questions. Results: Of the 182 EMS providers who completed the survey (100% response rate), 84.1% had cared for a hospice patient one or more times. Respondents included 86 (47.3%) EMTs with Intermediate and Advanced training and 96 (52.7%) Paramedics. Respondent's years of experience ranged from 0–10+ years, with 99 (54.3%) providers having 0–5 years of experience and 83 (45.7%) providers having 5+ years of experience. There were no significant differences between EMTs and Paramedics in their knowledge of the care of these patients, nor were there significant differences (p < 0.05) between those with 0–5 and 5+ years of experience. Furthermore, 53 (29.1%) EMS providers reported receiving formal education on the care of hospice patients. A total of 36% respondents felt that patients in hospice care required a DNR order. In EMS providers' open-ended responses on challenges in responding to the care needs of hospice patients, common themes were family-related challenges, and the need for more education. Conclusion: While the majority of EMS providers have responded to patients enrolled in hospice care, few providers received formal training on how to care for this population. EMS providers have expressed a need for a formal curriculum on the care of the patient receiving hospice.     

Y2K medical disaster preparedness in New York City: confidence of emergency department directors in their ability to respond

OBJECTIVES: To study the preparedness New York City for large scale medical disasters using the Year 2000 (Y2K) New Years Eve weekend as a model. METHODS: Surveys were sent to the directors of 51 of the 9-1-1-receiving hospitals in New York City before and after the Y2K weekend. Inquiries were made regarding hospital activities, contingencies, protocols, and confidence levels in the ability to manage critical incidents, including weapons of mass destruction (WMD) events. Additional information was collected from New York City governmental agencies regarding their coordination and preparedness. RESULTS: The pre-Y2K survey identified that 97.8% had contingencies for loss of essential services, 87.0% instituted their disaster plan in advance, 90.0% utilized an Incident Command System, and 73.9% had a live, mock Y2K drill. Potential terrorism influenced Y2K preparedness in 84.8%. The post-Y2K survey indicated that the threat of terrorism influenced future preparedness in 73.3%; 73.3% had specific protocols for chemical; 62.2% for biological events; 51.1% were not or only slightly confident in their ability to manage any potential WMD incidents; and 62.2% felt very or moderately confident in their ability to manage victims of a chemical event, but only 35.6% felt similarly about victims of a biological incident. Moreover, 80% felt there should be government standards for hospital preparedness for events involving WMD, and 84% felt there should be government standards for personal protective and DECON equipment. In addition, 82.2% would require a moderate to significant amount of funding to effect the standards. Citywide disaster management was coordinated through the Mayor's Office of Emergency Management. CONCLUSIONS: Although hospitals were on a heightened state of alert, emergency department directors were not confident in their ability to evaluate and manage victims of WMD incidents, especially biological exposures. The New York City experience is an example for the rest of the nation to underscore the need for further training and education of preparedness plans for WMD events. Federally supported education and training is available and is essential to improve the response to WMD threats.     

Anxiety levels in EMS providers: effects of violence and shifts schedules.

We tried to measure anxiety levels in emergency medical service (EMS) providers to determine the effects of (1) having had a violent encounter during a shift and (2) different shift schedules, conducting a prospective observational study over 3 months in an urban EMS system setting. A convenience sample of 23 EMTs and 40 EMT-Ps was observed. Anxiety levels were measured using the Spielberger State-Trait Anxiety Inventory. A total of 99 inventories were completed by 63 EMS providers. The mean state (32.6+/-8) and trait (31.7+/-7.1) scores were less than normative scores (35.7+/-10.4 and 34.9+/-9.2 respectively) for working adult males (P = .004 and .007, respectively). Paramedics had lower anxiety scores than basic EMTs (P = .015 and .039) and years of experience also decreased anxiety scores (P < .0001). There was no significant difference in state scores between those EMS providers who had encountered violence during the preceding 12 hours and those providers who had not. Comparisons of state scores of providers assessed at hour 12 of a 12 hour shift, hour 12 of a 24 hour shift, and hour 24 of a 24 hour shift failed to show any significant differences. Although the working environment of the EMS provider contains numerous stressors and uncertainties, this population of providers were no more anxious than the general working public. Advanced training and years of experience decreased anxiety. Violent encounters during a shift did not appear to affect anxiety levels. There was no difference in anxiety levels in providers who worked 12 and 24 hour shifts.     

EMS Provider Compliance with Infection Control Recommendations Is Suboptimal

Abstract

Introduction. Standard precautions are disease transmission prevention strategies recommended by both the World Health Organization (WHO) and by the Centers for Disease Control and Prevention (CDC). Emergency medical services (EMS) personnel are expected to utilize standard precautions. Methods. This was a prospective observational study of the use of standard precautions by EMS providers arriving at a large urban emergency department (ED). Research assistants (RAs) observed EMS crews throughout their arrival and delivery of patients and recorded data related to the use of gloves, hand hygiene, and equipment disinfection. Results. A total of 423 EMS deliveries were observed, allowing for observation of 899 EMS providers. Only 512 (56.9%) EMS providers arrived wearing gloves. Hand washing was observed in 250 (27.8%) of providers. Reusable equipment disinfection was noted in only 31.6% of opportunities. The most commonly disinfected item was the stretcher (55%). Conclusion. EMS provider compliance with standard precautions and equipment disinfection recommendations is suboptimal. Strategies must be developed to improve EMS provider compliance with internationally recognized infection control guidelines.     

Impact of a citywide blackout on an urban emergency medical services system

INTRODUCTION: On 14 August 2003, New York City and a large portion of the northeastern United States experienced the largest blackout in the history of the country. An analysis of such a widespread disaster on emergency medical service (EMS) operations may assist in planning for and managing such disasters in the future. METHODS: A retrospective review of all EMS activity within New York City's 9-1-1 emergency telephone system during the 29 hours during which all or parts of the city were without power (16:11 hours (h) on 14 August 2003 until 21:03 h on 15 August 2003) was performed. Control periods were established utilizing identical time periods during the five weeks preceding the blackout. RESULTS: Significant increases were identified in the overall EMS demand (7,844 incidents vs. 3,860 incidents; p < 0.001) as well as in 20 of the 62 call-types of the system, including cardiac arrests (119 vs. 76, p = 0.043). Significant decreases were found only among calls related to psychological emergencies (114 vs. 221; p = 0.006) and drug- or alcohol-related emergencies (78 vs. 146; p = 0.009). Though median response times increased by only 60 seconds, median call-processing times within the 9-1-1 emergency telephone system EMS dispatch center of the city increased from 1.1 to 5.5 minutes. CONCLUSIONS: The citywide blackout resulted in dramatic changes in the demands upon the EMS system of New York City, the types of patients for whom EMS providers were assigned to provide care, and the dispositions for those assignments. During this time of increased, system-wide demand, the use of cross-trained firefighter and first-responder engine companies resulted in improved response times to cardiac arrest patients. Finally, the ability of the EMS dispatch center to process the increased requests for EMS assistance proved to be the rate-limiting step in responding to these emergencies. These findings will prove useful in planning for future blackouts or any disaster that may broadly impact the infrastructure of a city.     

Mission failure: emergency medical services response to chemical, biological, radiological, nuclear, and explosive events

INTRODUCTION: Only 4% of the United States Homeland Security funding for public safety terrorism preparedness is allotted to emergency medical services (EMS), despite the primary threat from a mass-terrorism chemical weapons attack (MTCWA) being personal injury. This study examines the preparedness of the EMS to respond to, treat, and transport victims of such attacks. HYPOTHESIS: It was hypothesized that US EMS agencies lack the necessary equipment to mitigate large-scale morbidity and mortality from a MTCWA. METHODS: Seventy after-action reports from full-scale, chemical weapons exercises conducted in large cities across the US were examined by the Office of Domestic Preparedness, Chemical Weapons Improved Response Program to ascertain if EMS responders had personal protective equipment sufficient to operate at the scene of a MTCWA. RESULTS: Of the 50 after action reports that mentioned EMS personal protective equipment, only six (12%) EMS agencies equipped their staff with personal protective equipment. CONCLUSIONS: Results indicate that EMS responders are not prepared to safely respond to MTCWAs, which may result in a significant loss of life of victims and responders.     

Role of the physician in prehospital management of trauma: North American perspective

To some extent or another, physicians have been involved in emergency medical services (EMS) systems in North America for decades. Over the years, physicians from different specialties have been involved with EMS, occasionally as full-time or part-time employees of the EMS system but more often on a voluntary or small contractual basis. Regardless of the employment relationship, most states and provinces now require by statute that each EMS system, particularly those providing advanced life support (ALS) services, have a designated EMS medical director. However, in the United States and most of Canada, such physicians typically oversee EMS systems by acting as administrative medical supervisors, educators, mentors, and, in some cases, even as system managers. Throughout many European countries, the physician is the primary care provider for a large percentage of the serious prehospital medical emergencies. In contrast, throughout North America, basic emergency medical technicians (EMTs) and paramedics (specially trained ALS providers) serve as the EMS system medical director's surrogates. In this system of care, such physician surrogates provide almost all of the prehospital medical care interventions without any on-scene physician presence. Nevertheless, because of their medical supervisory requirements, by statute, North American medical directors generally are still accountable for patient care. Therefore, in many areas of the United States and Canada, the responsible physicians also respond to EMS scenes on a routine basis. They do so, both announced and unannounced, independently or with EMS personnel. In this capacity, they can serve as a direct patient care resource for the EMTs, paramedics, and the patients themselves. However, by becoming an intermittent participating member of the EMS team in the unique out-of-hospital setting, these on-scene physicians can help to better scrutinize the care rendered and thus more effectively modify applicable protocols and training as needed. Historically, such practices have helped many EMS systems-not only in terms of reforming traditional protocols but also by helping to establish improved medical care priorities and even system management changes that affect patient care. In addition, active participation helps the accountable EMS physician not only to identify weaknesses in personnel skills and system approaches, but it also provides an opportunity for role modeling, both medically and managerially.     

Termination of Resuscitation of Nontraumatic Cardiopulmonary Arrest: Resource Document for the National Association of EMS Physicians Position Statement

Abstract

In the development of an emergency medical services (EMS) system, medical directors should consider the implementation of protocols for the termination of resuscitation (TOR) of nontraumatic cardiopulmonary arrest. Such protocols have the potential to decrease unnecessary use of warning lights and sirens and save valuable public health resources. Termination-of-resuscitation protocols for nontraumatic cardiopulmonary arrest should be based on the determination that an EMS provider did not witness the arrest, there is no shockable rhythm identified, and there is no return of spontaneous circulation (ROSC) prior to EMS transport. Further research is needed to determine the need for direct medical oversight in TOR protocols and the duration of resuscitation prior to EMS providers’ determining that ROSC will not be achieved. This paper is the resource document to the National Association of EMS Physicians position statement on the termination of resuscitation for nontraumatic cardiopulmonary arrest.     

Mass Gathering Medical Care: Resource Document for the National Association of EMS Physicians Position Statement

Abstract

Mass gatherings are heterogeneous in terms of size, duration, type of event, crowd behavior, demographics of the participants and spectators, use of recreational substances, weather, and environment. The goals of health and medical services should be the provision of care for participants and spectators consistent with local standards of care, protection of continuing medical service to the populations surrounding the event venue, and preparation for surge to respond to extraordinary events. Pre–event planning among jurisdictional public health and EMS, acute care hospitals, and event EMS is essential, but should also include, at a minimum, event security services, public relations, facility maintenance, communications technicians, and the event planners and organizers. Previous documented experience with similar events has been shown to most accurately predict future needs. Future work in and guidance for mass gathering medical care should include the consistent use and further development of universally accepted consistent metrics, such as Patient Presentation Rate and Transfer to Hospital Rate. Only by standardizing data collection can evaluations be performed that link interventions with outcomes to enhance evidence-based EMS services at mass gatherings. Research is needed to evaluate the skills and interventions required by EMS providers to achieve desired outcomes. The event-dedicated EMS Medical Director is integral to acceptable quality medical care provided at mass gatherings; hence, he/she must be included in all aspects of mass gathering medical care planning, preparations, response, and recovery. Incorporation of jurisdictional EMS and community hospital medical leadership, and emergency practitioners into these processes will ensure that on-site care, transport, and transition to acute care at appropriate receiving facilities is consistent with, and fully integrated into the community's medical care system, while fulfilling the needs of event participants.     

Acute Pain Is Underassessed in Out-of-hospital Emergencies

OBJECTIVES: To evaluate the quality of pain assessment by emergency medical services (EMS) in out-of-hospital emergencies. METHODS: A prospective study was conducted on a convenience sample of patients during a one-year observation period. Pain ratings assessed by emergency patients were documented at three different intervals during the emergency call, and compared with concomitant assessments by EMS providers. A visual analog scale (VAS) and a verbal pain scale (VPS) were used for pain assessment. Repeated-measures ANOVA and Dunnett's t-test were used for data analysis. RESULTS: Fifty-one out of 70 eligible patients met inclusion criteria. In most emergency patients the intensity of pain was underestimated by EMS, especially when pain was severe (p = 0.0001). During the course of transport, both pain and pain assessment by EMS improved significantly (p = 0.0001). The VAS and VPS were significantly correlated (p = 0.0001). CONCLUSIONS: EMS providers significantly underestimate their patients' pain severity. EMS providers should be more attentive to their patients' complaints and comfort.     

Medical Oversight,Educational Core Content,and Proposed Scopes of Practice of Wilderness EMS Providers: A Joint Project Developed by Wilderness EMS Educators,Medical Directors,and Regulators Using a Delphi Approach

Introduction: A disparity exists between the skills needed to manage patients in wilderness EMS environments and the scopes of practice that are traditionally approved by state EMS regulators. In response, the National Association of EMS Physicians Wilderness EMS Committee led a project to define the educational core content supporting scopes of practice of wilderness EMS providers and the conditions when wilderness EMS providers should be required to have medical oversight. Methods: Using a Delphi process, a group of experts in wilderness EMS, representing educators, medical directors, and regulators, developed model educational core content. This core content is a foundation for wilderness EMS provider scopes of practice and builds on both the National EMS Education Standards and the National EMS Scope of Practice Model. These experts also identified the conditions when oversight is needed for wilderness EMS providers. Results: By consensus, this group of experts identified the educational core content for four unique levels of wilderness EMS providers: Wilderness Emergency Medical Responder (WEMR), Wilderness Emergency Medical Technician (WEMT), Wilderness Advanced Emergency Medical Technician (WAEMT), and Wilderness Paramedic (WParamedic). These levels include specialized skills and techniques pertinent to the operational environment. The skills and techniques increase in complexity with more advanced certification levels, and address the unique circumstances of providing care to patients in the wilderness environment. Furthermore, this group identified that providers having a defined duty to act should be functioning with medical oversight. Conclusion: This group of experts defined the educational core content supporting the specific scopes of practice that each certification level of wilderness EMS provider should have when providing patient care in the wilderness setting. Wilderness EMS providers are, indeed, providing health care and should thus function within defined scopes of practice and with physician medical director oversight.     

A self-assessment of Wisconsin prehospital provider needs

INTRODUCTION: The pressures facing emergency medical services (EMS) in Wisconsin and their effects on the delivery of prehospital emergency medical care were not known by the Wisconsin EMS Board. In an effort to assess these pressures and the needs of the emergency medical services in the State as perceived by the services, the Board undertook a survey of the EMS providers in Wisconsin. METHODS: A survey instrument was developed and approved by the EMS Board and distributed to all of the licensed emergency medical services in Wisconsin. RESULTS: Of the 453 survey instruments distributed, 323 (71.3%) were completed and returned. Intermediate- and paramedic-level services were more likely to respond than were the basic services, but 235 (72.8%) of the respondents identified their service levels as basic. In addition to providing information about the service characteristics, each responding service also rated the importance of their perceived needs. Lack of medical direction was perceived as the greatest need by all levels of service. However, the second greatest area of need for basic and intermediate services related to difficulty in recruiting new staff. For paramedic services, the second greatest need was associated with dispatching. When comparing services by rural versus urban, difficulty in recruiting new staff and collecting ambulance fees were seen as second and third to lack of a medical director by rural services, whereas urban services noted local training to be in the top three. In the assessment of educational needs, patient-care issues dominated. A review of written comments also demonstrated a difference between rural and urban services, but both noted Medicare and Medicaid reimbursement issues more commonly than any other problem. CONCLUSIONS: In the restructuring of health care, it will be important to consider the various needs of prehospital providers and recognize that such needs may be unique to the providers' location and level of service.
