Role of Emergency Medical Services in Disaster Response: Resource Document for the National Association of EMS Physicians Position Statement

Abstract The National Association of EMS Physicians (NAEMSP) advocates for a strong emergency medical services (EMS) role in all phases of disaster management—preparedness, response, and recovery. Emergency medical services administrators and medical directors should play a leadership role in preparedness activities such as training and education, development of performance metrics, establishment of memoranda of understanding (MOUs), and planning for licensure and liability issues. During both the planning and response phases, EMS leadership should advocate for participation in unified command, modified scope of practice appropriate for providers and the event, and expanded roles in community and federal response efforts. To enhance recovery, EMS leadership should strongly advocate for national recognition for EMS efforts and further research into strategies that foster healthy coping techniques and resiliency in the EMS workforce. This resource document will outline the basis for the corresponding NAEMSP position statement on the role of EMS in disaster management.

A poor association between out-of-hospital cardiac arrest location and public automated external defibrillator placement.

INTRODUCTION Much attention has been given to the strategic placement of automated external defibrillators (AEDs). The purpose of this study was to examine the correlation of strategically placed AEDs and the actual location of cardiac arrests. METHODS A retrospective review of data maintained by the Maryland Institute for Emergency Medical Services Systems (MIEMSS), specifically, the Maryland Cardiac Arrest Database and the Maryland AED Registry, was conducted. Location types for AEDs were compared with the locations of out-of-hospital cardiac arrests in Howard County, Maryland. The respective locations were compared using scatter diagrams and r2 statistics. RESULTS The r2 statistics for AED location compared with witnessed cardiac arrest and total cardiac arrests were 0.054 and 0.051 respectively, indicating a weak relationship between the two variables in each case. No AEDs were registered in the three most frequently occurring locations for cardiac arrests (private homes, skilled nursing facilities, assisted living facilities) and no cardiac arrests occurred at the locations where AEDs were most commonly placed (community pools, nongovernment public buildings, schools/educational facilities). CONCLUSION A poor association exists between the location of cardiac arrests and the location of AEDs.

Assessing attitudes toward spinal immobilization.

BACKGROUND Prospective studies have improved knowledge of prehospital spinal immobilization. The opinion of Emergency Medical Services (EMS) providers regarding spinal immobilization is unknown, as is their knowledge of recent research advances. STUDY OBJECTIVES To examine the attitudes, knowledge, and comfort of prehospital and Emergency Department (ED) EMS providers regarding spinal immobilization performed under a non-selective protocol. METHODS An online survey was conducted from May to July of 2011. Participants were drawn from the Howard County Department of Fire and Rescue Services and the Howard County General Hospital ED. The survey included multiple choice questions and responses on a modified Likert scale. Correlation analysis and descriptive data were used to analyze results. RESULTS Comfort using the Kendrick Extrication Device was low among ED providers. Experienced providers were more likely to indicate comfort using this device. Respondents often believed that spinal immobilization is appropriate in the management of penetrating trauma to the chest and abdomen. Reported use of padding decreased along with the frequency with which providers practice and encounter immobilized patients. Respondents often indicated that they perform spinal immobilization due solely to mechanism of injury. Providers who feel as if spinal immobilization is often performed unnecessarily were more likely to agree that immobilization causes an unnecessary delay in patient care. CONCLUSIONS The results demonstrate the need for improved EMS education in the use of the Kendrick Extrication Device, backboard padding, and spinal immobilization in the management of penetrating trauma. The attitudes highlighted in this study are relevant to the implementation of a selective spinal immobilization protocol.

Prevalence of unmet health care needs and description of health care-seeking behavior among displaced people after the 2007 California wildfires

OBJECTIVES The southern California wildfires in autumn 2007 resulted in widespread disruption and one of the largest evacuations in the states history. This study aims to identify unmet medical needs and health care-seeking patterns as well as prevalence of acute and chronic disease among displaced people following the southern California wildfires. These data can be used to increase the accuracy, and therefore capacity, of the medical response. METHODS A team of emergency physicians, nurses, and epidemiologists conducted surveys of heads of households at shelters and local assistance centers in San Diego and Riverside counties for 3 days beginning 10 days postdisaster. All households present in shelters on the day of the survey were interviewed, and at the local assistance centers, a 2-stage sampling method was used that included selecting a sample size proportionate to the number of registered visits to that site compared with all sites followed by a convenience sampling of people who were not actively being aided by local assistance center personnel. The survey covered demographics; needs following the wildfires (shelter, food, water, and health care); acute health symptoms; chronic health conditions; access to health care; and access to prescription medications. RESULTS Among the 175 households eligible, 161 (92.0%) households participated. Within the 47 households that reported a health care need since evacuation, 13 (27.7%) did not receive care that met their perceived need. Need for prescription medication was reported by 47 (29.2%) households, and 20 (42.6%) of those households did not feel that their need for prescription medication had been met. Mental health needs were reported by 14 (8.7%) households with 7 of these (50.0%) reporting unmet needs. At least 1 family member per household left prescription medication behind during evacuation in 46 households (28.6%), and 1 family member in 48 households (29.8%) saw a health care provider since their evacuation. Most people sought care at a clinic (24, 50.0%) or private doctor (11, 22.9%) as opposed to an emergency department (6, 12.5%). CONCLUSIONS A significant portion of the households reported unmet health care needs during the evacuations of the southern California wildfires. The provision of prescription medication and mental health services were the most common unmet need. In addition, postdisaster disease surveillance should include outpatient and community clinics, given that these were the most common treatment centers for the displaced population.

Effect of Reverse Triage on Creation of Surge Capacity in a Pediatric Hospital

Importance The capacity of pediatric hospitals to provide treatment to large numbers of patients during a large-scale disaster remains a concern. Hospitals are expected to function independently for as long as 96 hours. Reverse triage (early discharge), a strategy that creates surge bed capacity while conserving resources, has been modeled for adults but not pediatric patients. Objective To estimate the potential of reverse triage for surge capacity in an academic pediatric hospital. Design, Setting, and Participants In this retrospective cohort study, a blocked, randomized sampling scheme was used including inpatients from 7 units during 196 mock disaster days distributed across the 1-year period from December 21, 2012, through December 20, 2013. Patients not requiring any critical interventions for 4 successive days were considered to be suitable for low-risk immediate reverse triage. Data were analyzed from November 1, 2014, through November 21, 2016. Main Outcomes and Measures Proportionate contribution of reverse triage to the creation of surge capacity measured as a percentage of beds newly available in each unit and in aggregate. Results Of 3996 inpatients, 501 were sampled (268 boys [53.5%] and 233 girls [46.5%]; mean [SD] age, 7.8 [6.6] years), with 10.8% eligible for immediate low-risk reverse triage and 13.2% for discharge by 96 hours. The psychiatry unit had the most patients eligible for immediate reverse triage (72.7%; 95% CI, 59.6%-85.9%), accounting for more than half of the reverse triage effect. The oncology (1.3%; 95% CI, 0.0%-3.9%) and pediatric intensive care (0%) units had the least effect. Gross surge capacity using all strategies (routine patient discharges, full use of staffed and unstaffed licensed beds, and cancellation of elective and transfer admissions) was estimated at 57.7% (95% CI, 38.2%-80.2%) within 24 hours and 84.1% (95% CI, 63.9%-100%) by day 4. Net surge capacity, estimated by adjusting for routine emergency department admissions, was about 50% (range, 49.1%-52.6%) throughout the 96-hour period. By accepting higher-risk patients only (considering only major critical interventions as limiting), reverse triage would increase surge capacity by nearly 50%. Conclusions and Relevance Our estimates indicate considerable potential pediatric surge capacity by using combined strategic initiatives. Reverse triage adds a meaningful but modest contribution and may depend on psychiatric space. Large volumes of pediatric patients discharged early to the community during disasters could challenge pediatricians owing to the close follow-up likely to be required.

Variables associated with effects on morbidity in older adults following disasters

Introduction: Older adults are vulnerable to disproportionately higher morbidity following disasters. Reasons for this vulnerability are multifaceted and vary by disaster type as well as patient comorbidities. Efforts to mitigate this increased morbidity require identification of at-risk older adults who can be targeted for intervention. Methods: A PubMed search was performed using the search terms “geriatric, disaster” and “morbidity, disaster” to identify published articles that reported variables associated with increased morbidity of older adults during and after disasters. A review of article titles and abstracts was then conducted to identify those articles that contained evidence-based variables that render older adults vulnerable to poor health outcomes during disasters. Results: A total of 233 studies was initially identified. After applying exclusion criteria, nine studies were chosen for the comprehensive review. Based on the synthesis of the literature, factors were identified that were repeatedly associated with morbidity and mortality among older adults during and shortly after disasters. Conclusion: Older adults, especially those with multiple co-morbidities, are at risk of increased morbidity after disasters and catastrophic events. Factors such as the need for prescription medications, low social support, visual and hearing impairment, impaired mobility, and poor economic status are associated with an increased risk of morbidity.

A Long Night in the Emergency Department during the Baltimore, Maryland (USA) Riots.

No one in the emergency department (ED) expected it to be a busy night. In the days prior, Baltimore (Maryland USA) residents protested the death of Freddie Gray while he was in police custody. This day, a Monday, the day of his funeral, we were not expecting violent protests or riots. Unfortunately, this was not the case. The events of the evening left a permanent impression on most of us that would not soon dissipate.... Language: en

Assessing pediatric and young adult substance use through analysis of prehospital data

INTRODUCTION Substance use in young adults is a significant and growing problem. Emergency Medical Services (EMS) personnel often encounter this problem, yet the use of prehospital data to evaluate the prevalence and magnitude of substance abuse has been limited. HYPOTHESIS/PROBLEM This study evaluated drug and alcohol use through the use of prehospital and EMS data in one suburban county in Maryland (USA). The primary hypothesis was that the type of drug being abused is associated with age. The secondary hypothesis was substance abuse incidence is associated with location. The tertiary hypothesis was that substance abuse is associated with a history of mental illness. METHODS Deidentified patient care reports (PCRs) were obtained during a 24-month period from October 2010 through September 2012 for patients 0 through 25 years of age. Inclusion criteria included chief complaint of alcohol overdose, drug overdose, or the use of naloxone. RESULTS The primary hypothesis was supported that age was associated with drug category (P < .001). Younger adolescents were more likely to use household items, prescription drugs, or over-the-counter drugs, whereas older adolescents were more likely to use illicit drugs. The secondary hypothesis was supported that both alcohol (P < .001) and drugs (P < .001) were associated with location of call. Calls involving alcohol were more likely to be at a home or business, whereas calls involving drugs were more likely to be at home or at a public venue. The tertiary hypothesis was supported that both alcohol (P = .001) and drug use (P < .001) were associated with history of mental illness. Older adolescents were more likely to report a history of mental illness. Chi-squared tests indicated there were significant differences between genders and drug category (P = .002) and gender and current suicide attempt (P = .004). Females were more likely to use prescription drugs, whereas males were more likely to use illicit drugs. Calls involving younger adolescents under 18 were more likely to be at school or the mall, whereas calls involving older adolescents were likely to be at a prison, public venue, or a business. CONCLUSION All three hypotheses were supported: the type of substance being abused was associated with both age and location, and substance abuse was associated with a history of mental illness. This research has important implications for understanding how EMS resources are utilized for substance use. This information is valuable in not only the education and training of prehospital care providers, but also for the targeting of future public health interventions.

A fire department community health intervention to prevent carbon monoxide poisoning following a hurricane.

Portable generators are commonly used during electrical service interruptions that occur following large storms such as hurricanes. Nearly all portable generators use carbon based fuels and produce deadly carbon monoxide gas. Despite universal warnings to operate these generators outside only, the improper placement of generators makes these devices the leading cause of engine related carbon monoxide deaths in the United States. The medical literature reports many cases of Carbon Monoxide (CO) toxicity associated with generator use following hurricanes and other weather events. This paper describes how Howard County, Maryland Fire and Rescue (HCFR) Services implemented a public education program that focused on prevention of Carbon Monoxide poisoning from portable generator use in the wake of events where electrical service interruptions occurred or had the potential to occur. A major challenge faced was communication with those members of the population who were almost completely dependent upon electronic and wireless technologies and were without redundancies. HCFR utilized several tactics to overcome this challenge including helicopter based surveillance and the use of geocoded information from the electrical service provider to identify outage areas. Once outage areas were identified, HCFR personnel conducted a door-to-door canvasing of effected communities, assessing for hazards and distributing information flyers about the dangers of generator use. This effort represents one of the first reported examples of a community-based endeavor by a fire department to provide proactive interventions designed to prevent carbon monoxide illness.
