Bleeding Control Protections Within US Good Samaritan Laws.

INTRODUCTION: In the United States, all 50 states and the District of Columbia have Good Samaritan Laws (GSLs). Designed to encourage bystanders to aid at the scene of an emergency, GSLs generally limit the risk of civil tort liability if the care is rendered in good faith. Nation-wide, a leading cause of preventable death is uncontrolled external hemorrhage. Public bleeding control initiatives aim to train the public to recognize life-threatening external bleeding, perform life-sustaining interventions (including direct pressure, tourniquet application, and wound packing), and to promote access to bleeding control equipment to ensure a rapid response from bystanders. METHODS: This study sought to identify the GSLs in each state and the District of Columbia to identify what type of responder is covered by the law (eg, all laypersons, only trained individuals, or only licensed health care providers) and if bleeding control is explicitly included or excluded in their Good Samaritan coverage. RESULTS: Good Samaritan Laws providing civil liability qualified immunity were identified in all 50 states and the District of Columbia. One state, Oklahoma, specifically includes bleeding control in its GSLs. Six states - Connecticut, Illinois, Kansas, Kentucky, Michigan, and Missouri - have laws that define those covered under Good Samaritan immunity, generally limiting protection to individuals trained in a standard first aid or resuscitation course or health care clinicians. No state explicitly excludes bleeding control from their GSLs, and one state expressly includes it. CONCLUSION: Nation-wide across the United States, most states have broad bystander coverage within GSLs for emergency medical conditions of all types, including bleeding emergencies, and no state explicitly excludes bleeding control interventions. Some states restrict coverage to those health care personnel or bystanders who have completed a specific training program. Opportunity exists for additional research into those states whose GSLs may not be inclusive of bleeding control interventions.

Dispatch Categories as Indicators of Out-of-Hospital Time Critical Interventions and Associated Emergency Department Outcomes.

OBJECTIVES: Emergency medical services (EMS) systems increasingly grapple with rising call volumes and workforce shortages, forcing systems to decide which responses may be delayed. Limited research has linked dispatch codes, on-scene findings, and emergency department (ED) outcomes. This study evaluated the association between dispatch categorizations and time-critical EMS responses defined by prehospital interventions and ED outcomes. Secondarily, we proposed a framework for identifying dispatch categorizations that are safe or unsafe to hold in queue. METHODS: This retrospective, multi-center analysis encompassed all 9-1-1 responses from 8 accredited EMS systems between 1/1/2021 and 06/30/2023, utilizing the Medical Priority Dispatch System (MPDS). Independent variables included MPDS Protocol numbers and Determinant levels. EMS treatments and ED diagnoses/dispositions were categorized as time-critical using a multi-round consensus survey. The primary outcome was the proportion of EMS responses categorized as time-critical. A non-parametric test for trend was used to assess the proportion of time-critical responses Determinant levels. Based on group consensus, Protocol/Determinant level combinations with at least 120 responses (∼1 per week) were further categorized as safe to hold in queue (<1% time-critical intervention by EMS and <5% time-critical ED outcome) or unsafe to hold in queue (>10% time-critical intervention by EMS or >10% time-critical ED outcome). RESULTS: Of 1,715,612 EMS incidents, 6% (109,250) involved a time-critical EMS intervention. Among EMS transports with linked outcome data (543,883), 12% had time-critical ED outcomes. The proportion of time-critical EMS interventions increased with Determinant level (OMEGA: 1%, ECHO: 38%, p-trend < 0.01) as did time-critical ED outcomes (OMEGA: 3%, ECHO: 31%, p-trend < 0.01). Of 162 unique Protocols/Determinants with at least 120 uses, 30 met criteria for safe to hold in queue, accounting for 8% (142,067) of incidents. Meanwhile, 72 Protocols/Determinants met criteria for unsafe to hold, accounting for 52% (883,683) of incidents. Seven of 32 ALPHA level Protocols and 3/17 OMEGA level Protocols met the proposed criteria for unsafe to hold in queue. CONCLUSIONS: In general, Determinant levels aligned with time-critical responses; however, a notable minority of lower acuity Determinant level Protocols met criteria for unsafe to hold. This suggests a more nuanced approach to dispatch prioritization, considering both Protocol and Determinant level factors.

Emergency Medical Services Protocols for Assessment and Treatment of Patients with Ventricular Assist Devices.

BACKGROUND: Patients with ventricular assist devices (VADs) represent a growing population presenting to Emergency Medical Services (EMS), but little is known about their prehospital care. This study aimed to characterize current EMS protocols in the United States for patients with VADs. METHODS: States with state-wide EMS protocols were included. Protocols were obtained from the state EMS website. If not available, the office of the state medical director was contacted. For each state, protocols were analyzed for patient and VAD assessment and treatment variables. RESULTS: Of 32 states with state-wide EMS protocols, 21 had VAD-specific protocols. With 17 (81%) states noting a pulse may not be palpable, protocols recommended assessing alternate measures of perfusion and mean arterial pressure (MAP; 15 [71%]). Assessment of VAD was advised through listening for pump hum (20 [95%]) and alarms (20 [95%]) and checking the power supply (15 [71%]). For treatment, EMS prehospital consultation was required to begin chest compression in three (14%) states, and mechanical (device) chest compressions were not permitted in two (10%) states. Contact information for VAD coordinator was listed in a minority of five (24%) states. Transport of VAD equipment/backup bag was advised in 18 (86%) states. DISCUSSION: This national analysis of EMS protocols found VAD-specific EMS protocols are not universally adopted in the United States and are variable when implemented, highlighting a need for VAD teams to partner with EMS agencies to inform standardized protocols that optimize these patients' care.

Implementation of a prehospital whole blood program: Lessons learned.

Early blood administration by Emergency Medical Services (EMS) to patients suffering from hemorrhagic shock improves outcomes. Prehospital blood programs represent an invaluable resuscitation capability that directly addresses hemorrhagic shock and mitigates subsequent multiple organ dysfunction syndrome. Prehospital blood programs must be thoughtfully planned, have multiple safeguards, ensure adequate training and credentialing processes, and be responsible stewards of blood resources. According to the 2022 best practices model by Yazer et al, the four key pillars of a successful prehospital program include the following: (1) the rationale for the use and a description of blood products that can be transfused in the prehospital setting, (2) storage of blood products outside the hospital blood bank and how to move them to the patient in the prehospital setting, (3) prehospital transfusion criteria and administration personnel, and (4) documentation of prehospital transfusion and handover to the hospital team.  This concepts paper describes our operational experience using these four pillars to make Maryland's inaugural prehospital ground-based low-titer O-positive whole blood program successful. These lessons learned may inform other EMS systems as they establish prehospital blood programs to help improve outcomes and enhance mass casualty response.

Efficacy and Safety of Prehospital Diltiazem.

OBJECTIVE: This study assesses the likelihood of clinical improvement and adverse events from EMS-administered diltiazem. Current prehospital protocols direct paramedics to administer diltiazem, a calcium channel blocker, to decrease the heart rate (HR) of symptomatic, hemodynamically stable patients with rapid atrial fibrillation. However, diltiazem can also cause systemic hypotension and bradycardia, which can precipitate end-organ injury. . METHODS: To assess whether the rate control benefit of prehospital diltiazem outweighs the risk of adverse events, we conducted a retrospective chart review of all adult patients who received diltiazem from Maryland Advanced Life Support EMS clinicians between January 1, 2019, and March 31, 2022. Collected data included patient demographics, vital signs, diltiazem dose, transport times, administered medications, and procedures. The main outcomes were clinical improvement (HR <100 beats per minute or ≥20% decrease from the maximum HR) and adverse events (bradycardia or hypotension). Multivariable logistic regression was used for statistical analysis. RESULTS: During the study period, 2396 patients received prehospital diltiazem and 94% of these patients (n = 2254) were included in the study. Overall, 1414 (63.8%) patients improved clinically, 604 (27.3%) patients achieved rate control as defined by a HR of <100 beats per minute, and 78 patients (3.5%) experienced an adverse event. Patients over the age of 50 were less likely to clinically improve with diltiazem administration. Adverse events were more likely in patients with systolic blood pressures (SBP) less than 140 mmHg, patients with maximum HR of less than 120 beats per minute, and patients who received nitroglycerin. CONCLUSIONS: Prehospital diltiazem is effective and safe for most patients. Adverse events are more likely in patients with baseline SBP less than 140 mmHg, HR less than 120 beats per minute, and concurrent nitroglycerin administration. Future opportunities for research include examining the relationship between adverse events and underlying etiology as well as investigating downstream outcomes.

Do prehospital sepsis alerts decrease time to complete CMS sepsis measures?

INTRODUCTION: In an effort to improve sepsis outcomes the Centers for Medicare and Medicaid Services (CMS) established a time sensitive sepsis management bundle as a core quality measure that includes blood culture collection, serum lactate collection, initiation of intravenous fluid administration, and initiation of broad-spectrum antibiotics. Few studies examine the effects of a prehospital sepsis alert protocol on decreasing time to complete CMS sepsis core measures. METHODS: This study was a retrospective cohort study of patients transported via EMS from December 1, 2018 to December 1, 2019 who met the criteria of the Maryland Statewide EMS sepsis protocol and compared outcomes between patients who activated a prehospital sepsis alert and patients who did not activate a prehospital sepsis alert. The Maryland Institute for Emergency Medical Services Systems developed a sepsis protocol that instructs EMS providers to notify the nearest appropriate facility with a sepsis alert if a patient 18 years of age and older is suspected of having an infection and also presents with at least two of the following: temperature >38 °C or <35.5 °C, a heart rate >100 beats per minute, a respiratory rate >25 breaths per minute or end-tidal carbon dioxide less than or equal to 32 mmHg, a systolic blood pressure <90 mmHg, or a point of care lactate reading greater than or equal to 4 mmol/L. RESULTS: Median time to achieve all four studied CMS sepsis core measures was 103 min [IQR 61-153] for patients who received a prehospital sepsis alert and 106.5 min [IQR 75-189] for patients who did not receive a prehospital sepsis alert (p-value 0.105). Median time to completion was shorter for serum lactate collection (28 min. vs 35 min., p-value 0.019), blood culture collection (28 min. vs 38 min., p-value <0.01), and intravenous fluid administration (54 min. vs 61 min., p-value 0.025) but was not significantly different for antibiotic administration (94 min. vs 103 min., p-value 0.12) among patients who triggered a sepsis alert. CONCLUSION: This study questions the effectiveness of prehospital sepsis alert protocols on decreasing time to complete CMS sepsis core measures. Future studies should address if these times can be impacted by having EMS providers independently administer antibiotics.

Safety of Nurse-Managed Inhaled Nitric Oxide During Critical Care Interfacility Transport.

Inhaled nitric oxide (iNO) is an advanced therapy typically managed by physicians and respiratory therapists in order to increase arterial oxygenation and decrease pulmonary arterial pressure. The Johns Hopkins Lifeline Critical Care Transportation Program (Lifeline) initiated a novel nurse-managed iNO protocol in order to optimize the oxygenation of critically ill patients during interfacility transport. This study was a retrospective chart review of adverse events associated with iNO initiation or continuation by Lifeline on patients transported from March 1, 2020, to August 1, 2022. Basic demographic data and adverse events were recorded. Recorded adverse events included hypotension defined as a mean arterial pressure (MAP) < 65 mm Hg, hypoxemia defined as a decrease of ≥ 10% arterial oxygenation saturation measured by pulse oximetry, new bradycardia or tachyarrhythmia, nitrogen dioxide (NO2) levels greater than 1.0 ppm, methemoglobinemia, and cardiac arrest. Fifteen patients were diagnosed with SARS-CoV-2 infection, of which one also had pulmonary emboli, 2 had bacterial pneumonia, 1 suffered cardiogenic shock from occlusive myocardial infarction and were on VA-ECMO, and 2 had significant thoracic trauma resulting in pulmonary contusions and hemopneumothorax. iNO was continued on 10 patients and initiated on 8 patients, 2 of whom were transitioned from inhaled epoprostenol. Hypotension occurred in 3 (16.7%) patients and one (5.56%) of the hypotensive patients subsequently went on to experience new atrial fibrillation with vasopressor titration. No patients developed worsening hypoxemia, elevated NO2 levels, methemoglobinemia, or suffered cardiac arrest. All 3 patients who experienced hypotension were already on vasopressor support and the hypotension resolved with medication titration. This study shows that iNO administration can be safely managed by appropriately trained nurses.

Establishing consensus-based high-acuity low-occurrence skills for EMS physicians: A pilot survey of EMS fellowship faculty.

Background: The specialty of emergency medical services (EMS) medicine focuses on providing out-of-hospital patient care, including initial stabilization, treatment, and transport in specially equipped vehicles including ambulances and airframe platforms to hospitals and better-resourced destinations. The Core Content of EMS Medicine outlines the knowledge, procedures, and psychomotor skills relevant to prehospital patient care. However, this document does not specify the high-consequence skills that are infrequently performed and that carry high levels of complexity as well as potential morbidity. We refer to these as high-acuity low-occurrence (HALO) skills. Additionally, there is no consensus definition of what meets the criteria for a HALO skill. The goals of this pilot study were twofold: (1) to determine a consensus definition for a HALO skill and (2) to survey EMS fellowship faculty to identify an initial set of EMS physician trainee skills that meet the HALO definition. Methods: Using a modified Delphi method, we established a consensus definition of a HALO skill as well as skills that met this definition for EMS physicians. Demographic information was collected from the experts. Results: There was 100% agreement in the definition provided of a HALO skill. No additional proposed definitions were provided. Thirteen HALO skills were suggested by the panel from the originally proposed 56 skills, requiring three rounds to establish consensus. Final skill domains emphasized by the expert panel include airway management, obstetric emergencies, and shock management. Conclusions: We present an initial consensus definition of a HALO skill and a recommended list of HALO skills for EMS physicians in training. Opportunity exists for further research to validate the definition and list of HALO skills through the sampling of a broader group of EMS physicians.

Temporal Changes in Epinephrine Dosing in Out-of-Hospital Cardiac Arrest: A Review of EMS Protocols across the United States.

BACKGROUND: Administration of epinephrine has been associated with worse neurological outcomes for survivors of out-of-hospital cardiac arrest. The publication of the 2018 PARAMEDIC-2 trial, a randomized and double-blind study of epinephrine in out-of-hospital cardiac arrest, provides the strongest evidence to date that epinephrine increases return of spontaneous circulation (ROSC) but not neurologically intact survival. This study aims to determine if Emergency Medical Services (EMS) cardiac arrest protocols have changed since the publication of PARAMEDIC-2. METHODS: States in the US utilizing mandatory or model state-wide EMS protocols, including Washington DC, were included in this study. The nontraumatic cardiac arrest protocol as of January 1, 2018 was compared to the protocol in effect on January 1, 2021 to determine if there was a change in the administration of epinephrine. Protocols were downloaded from the relevant state EMS website. If a protocol could not be obtained, the state medical director was contacted. RESULTS: A 2021 state-wide protocol was found for 32/51 (62.7%) states. Data from 2018 were available for 21/51 (41.2%) states. Of the 11 states without data from 2018, all follow Advanced Cardiac Life Support (ACLS) guidelines in the 2021 protocol. Five (15.6%) of the states with a state-wide protocol made a change in the cardiac arrest protocols. Maximum cumulative epinephrine dose was limited to 4mg in Maryland and 3mg in Vermont. Rhode Island changed epinephrine in shockable rhythms to be administered after three cycles of cardiopulmonary resuscitation (CPR) and an anti-arrhythmic. Rhode Island also added an epinephrine infusion as an option. No states removed epinephrine administration from their cardiac arrest protocol. Simple statistical analysis was performed with Microsoft Excel. CONCLUSION: Several states have adjusted cardiac arrest protocols since 2018. The most frequent change was limiting the maximum cumulative dosage of epinephrine. One state changed timing of epinephrine dosing depending on the rhythm and also provided an option of an epinephrine infusion in place of bolus dosing. While the sample size is small, these changes may reflect the future direction of prehospital cardiac arrest protocols. Significant limitations apply, including the exclusion of local and regional protocols which are more capable of quickly adjusting to new research. Additionally, this study is only focused on EMS in the United States.

A Statewide EMS Viral Syndrome Pandemic Triage Protocol: 24 Hour Outcomes.

Background: Early during the COVID-19 pandemic, Emergency Medical Services (EMS) systems encountered many challenges that prompted crisis-level strategies. Maryland's statewide EMS system implemented the Viral Syndrome Pandemic Triage Protocol which contained a decision tool to help identify patients potentially safe for self-care at home. Objectives: This study assessed the effects of the Maryland Viral Syndrome Pandemic Triage Protocol and the safety of referring patients for self-care at home. Methods: This is a retrospective statewide analysis of EMS patients from March 19 thru September 4, 2020, who were not transported and had documentation of the Viral Syndrome Pandemic Triage Protocol's decision support tool completed, as well as a random sample of 150 patients who were not transported and did not have documentation of the decision tool. Descriptive statistics were performed as well as a two-stage multivariable logistic regression model for the outcomes of ED presentation within 24 hours and subsequent hospitalization. Results: 301 EMS patients were documented as triaged to home using the protocol and outcomes data were available for 282 (94%). 41(14.5%) patients presented to an ED within 24 hours and 14 (5% of 282) required inpatient hospitalization. Nine (3.2%) patients were subsequently hospitalized with a diagnosis of COVID-19 illness. Of those patients for whom the decision tool was not documented, 35 (23%) had an ED visit within 24 hours and 15 (10%) were hospitalized (p = 0.075). Multivariate logistic regression model results (N = 432) suggest that those with documentation of triage protocol use had some advantage over those patients without documentation. The 95% CIs of the estimated effect of Triage/No Triage protocol documented were wide and crossed the 1.0 limit but overall, all effects Odds Ratios and Adjust Odds Ratios were consistently over 1.0 with the lowest value of 1.3 and the highest value of 2.1. Conclusion: Most patients (95%) who were triaged to self-care at home with home documented decision support tool use did not require hospitalization within 24 hours following EMS encounter and this appears to be safe. Future opportunity exists to incorporate such tools into comprehensive pandemic preparedness strategies along with appropriate follow up and quality improvement mechanisms.

Haddon matrix analysis of medical preparedness for mass gathering music festivals.

Beginning in the 1960s as a tool to disaggregate complicated auto injuries, the Haddon matrix has evolved into a modern method of analyzing complex public health challenges. Throughout the United States and internationally, music festivals have become a rapidly growing and increasingly complex area of mass gathering medicine. Given the austere environment and inherent challenges of providing medical care during a music festival, we utilized a modified Haddon matrix. The objective is to assess the relevant human, physical, and sociocultural factors that impact these festivals throughout the pre-event, event, and post-event time periods. This will ensure an all-hazards preparedness approach to the historically high incidence of traumatic injuries and polysubstance abuse, coupled with modern challenges such as infectious diseases and acts of intentional violence.

911 EMS Activations by Pregnant Patients in Maryland (USA) during the COVID-19 Pandemic.

INTRODUCTION: In the early phase of the coronavirus disease 2019 (COVID-19) pandemic, United States Emergency Medical Services (EMS) experienced a decrease in calls, and at the same time, an increase in out-of-hospital deaths. This finding led to a concern for the implications of potential delays in care for the obstetric population. HYPOTHESIS/PROBLEM: This study examines the impact of the pandemic on prehospital care amongst pregnant women. METHODS: A retrospective observational study was conducted comparing obstetric-related EMS activations in Maryland (USA) during the pandemic (March 10-July 20, 2020) to a pre-pandemic period (March 10-July 20, 2019). Comparative analysis was used to analyze the difference in frequency and acuity of calls between the two periods. RESULTS: There were fewer obstetric-related EMS encounters during the pandemic compared to the year prior (daily average during the pandemic 12.5 [SD = 3.8] versus 14.6 [SD = 4.1] pre-pandemic; P <.001), although the percent of total female encounters remained unchanged (1.6% in 2020 versus 1.5% in 2019; P = .091). Key indicators of maternal status were not significantly different between the two periods. African-American women represented a disproportionately high percentage of obstetric-related activations (36.2% in 2019 and 34.8% in 2020). CONCLUSIONS: In this state-wide analysis of EMS calls in Maryland early in the pandemic, no significant differences existed in the utilization of EMS by pregnant women. Prehospital EMS activations amongst pregnant women in Maryland only decreased slightly without an increase in acuity. Of note, over-representation by African-American women compared to population statistics raises concern for broader systemic differences in access to obstetric care.

Decision Making and Interventions During Interfacility Transport of High-Acuity Patients With Severe Acute Respiratory Syndrome Coronavirus 2 Infection.

OBJECTIVE: There are limited data regarding the typical characteristics of coronavirus disease 2019 (COVID-19) patients requiring interfacility transport or the clinical capabilities of the out-of-hospital transport clinicians required to provide safe transport. The objective of this study is to provide epidemiologic data and highlight the clinical skill set and decision making needed to transport critically ill COVID-19 patients. METHODS: A retrospective chart review of persons under investigation for COVID-19 transported during the first 6 months of the pandemic by Johns Hopkins Lifeline was performed. Patients who required interfacility transport and tested positive for severe acute respiratory syndrome coronavirus 2 by polymerase chain reaction assay were included in the analysis. RESULTS: Sixty-eight patients (25.4%) required vasopressor support, 35 patients (13.1%) were pharmacologically paralyzed, 15 (5.60%) were prone, and 1 (0.75%) received an inhaled pulmonary vasodilator. At least 1 ventilator setting change occurred for 59 patients (22.0%), and ventilation mode was changed for 11 patients (4.10%) during transport. CONCLUSION: The safe transport of critically ill patients with COVID-19 requires experience with vasopressors, paralytic medications, inhaled vasodilators, prone positioning, and ventilator management. The frequency of initiated critical interventions and ventilator adjustments underscores the tenuous nature of these patients and highlights the importance of transport clinician reassessment, critical thinking, and decision making.

Establishing Consensus-based Objectives for the Creation of an Opioid Overdose Curriculum for Emergency Medical Services Clinicians.

OBJECTIVES: Emergency medical services (EMS) clinicians are on the front lines of the opioid epidemic and are often the first health care personnel system to contact patients experiencing opioid toxicity. Although national educational guidelines include opioid toxicity, no specific standardized prehospital educational objectives or competencies exist. The goal of this project was to identify objectives for an EMS opioid toxicity curriculum that could be used for EMS training. METHODS: A list of preliminary educational objectives from U.S. EMS training programs was compiled and reviewed by a group of experts. The Delphi method was used to attain consensus on a final list of objectives for an EMS opioid curriculum. RESULTS: A total of 107 opioid-related preliminary objectives were identified and then narrowed down to 81 preliminary objectives after accounting for redundancy. After four successive rounds of evaluating/accepting/rejecting objectives, 18 final objectives were identified and unanimously approved by the expert panel. CONCLUSION: We identified 18 objectives to serve as a framework for an opioid toxicity curriculum for EMS clinicians. These objectives can serve as a basis for creating a standardized didactic training program for EMS training programs nationwide. Further evaluation will be needed to explore the best means for educational program delivery.

Position Statement: Mass Gathering Medical Care.

The National Association of Emergency Medicine Services (EMS) Physicians (NAEMSP) recognizes the continued growth and complexity of mass gathering events and the integral role of the medical director in their planning and management. There is a growing body of literature that provides additional insight into patient presentations as well as preparation, staffing, and planning for these events. The clinical practice of EMS medicine encompasses the provision of care in a variety of out-of-hospital environments, including those defined as mass gathering events. This updated guidance is intended for use by EMS personnel, EMS medical directors, emergency physicians, and other members of the multidisciplinary care team as they strive to provide the best care for patients in a variety of out-of-hospital environments. This document is not meant to be a complete review of all the issues on this topic, but rather a consensus statement based on the combination of available peer-reviewed, published evidence and expert opinion.

A Critical Care Transport Program's Innovative Approach to Safety During the Coronavirus Disease 2019 Pandemic.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic has resulted in the frequent transfer of critically ill patients, yet there is little information available to assist critical care transport programs in protecting their clinicians from disease exposure in this unique environment. The Lifeline Critical Care Transport Program has implemented several novel interventions to reduce the risk of staff exposure. METHODS: Several safety interventions were implemented at the beginning of the COVID-19 pandemic. These initiatives included the deployment of a transport safety officer, a receiving clean team for select interfacility transports, and modifications in personal protective equipment. RESULTS: From February 29, 2020, to August 29, 2020, there were 1,041 transports of persons under investigation, 660 (63.4%) of whom were ultimately found to be COVID-19 positive. Approximately one third were ground transports, 11 (1.1%) were by air, and the remainder were intrahospital transports. There were 0 documented staff exposures or illnesses during the study period. CONCLUSION: The adaptation of these safety measures resulted in 0 staff exposures or illnesses while maintaining a high-volume, high-acuity critical care transport program. These interventions are the first of their kind to be implemented during the COVID-19 pandemic and offer a framework for other organizations and future disease outbreaks.

Best Practices for a Novel EMS-Based Naloxone Leave behind Program.

BACKGROUND: Increasing naloxone access has been identified as a primary strategy to reduce opioid overdose deaths. To supplement community naloxone training and distribution access points, EMS systems have instituted public safety-based naloxone leave behind (NLB) programs that allow emergency medical responders to distribute "leave behind" naloxone kits on the scene of an overdose. This model presents an opportunity to expand naloxone access for individuals at high risk for future overdoses. Objectives: To evaluate the preliminary outcomes of a novel EMS-based NLB program in Howard County, Maryland. Methods: This exploratory study involved analysis of data from the Howard County NLB Program. Basic statistical analysis of program performance metrics and participant demographic characteristics were performed. Results: From June 2018 to June 2019, Howard County Department of Fire and Rescue Services responded to 239 overdose calls and distributed 120 naloxone kits to individuals on the scene of an overdose, a 50.21% distribution rate. The HCNLB program connected 143 patients (59.83%) to peer recovery specialists. Among the 143 patients linked to peer recovery support specialist services, 87 (60.84%) had accepted an NLB kit from EMS. The fully adjusted logistic regression model revealed that those whose kit was left with a family member on the scene were 5.16 times more likely to be connected to peer support specialists (OR = 5.16, CI= 2.35 - 11.29, p = 0.000) while those whose kit was left with a friend or given directly to the patient were 3.69 times (OR = 3.69, CI= 1.13 - 12.06, p < 0.05) and 2.37 times (OR = 2.37, CI= 1.10 - 5.14, p < 0.05) more likely, respectively, to be connected to follow up services as compared to those who did not accept a kit, controlling for other variables in the model. Conclusion: This study highlights the importance of engaging an individual's family and social network when offering connections to treatment and recovery resources. NLB initiatives can potentially augment existing community-based naloxone training structures, thus widening the scope of the life-saving drug and reaching those most at risk of dying from an opioid overdose.

Removal of the Prehospital Tourniquet in the Emergency Department.

BACKGROUND: Life-threatening hemorrhage from extremity injuries can be effectively controlled in the prehospital environment through direct pressure, wound packing, and the use of tourniquets. Early tourniquet application has been prioritized for rapid control of severe extremity hemorrhage and is a cornerstone of prehospital trauma resuscitation guidelines. Emergency physicians must be knowledgeable regarding the initial assessment and appropriate management of patients who present with a prehospital tourniquet in place. DISCUSSION: An interdisciplinary group of experts including emergency physicians, trauma surgeons, and tactical and Emergency Medical Services physicians collaborated to develop a stepwise approach to the assessment and removal (discontinuation) of an extremity tourniquet in the emergency department after being placed in the prehospital setting. We have developed a best-practices guideline to serve as a resource to aid the emergency physician in how to safely remove a tourniquet. The guideline contains five steps that include: 1) Determine how long the tourniquet has been in place; 2) Evaluate for contraindications to tourniquet removal; 3) Prepare for tourniquet removal; 4) Release the tourniquet; and 5) Monitor and reassess the patient. CONCLUSION: These steps outlined will help emergency medicine clinicians appropriately evaluate and manage patients presenting with tourniquets in place. Tourniquet removal should be performed in a systematic manner with plans in place to immediately address complications.

A Longitudinal Analysis of a Law Enforcement Intranasal Naloxone Training Program.

INTRODUCTION: The opioid crisis continues to claim lives at historically unprecedented levels and shows few signs of abating. One means of mitigating the harm from opioid abuse and unintentional overdose is training and equipping police officers to administer intranasal (IN) naloxone as part of a broader public health response. While an increasing number of state and local agencies have implemented law enforcement officer (LEO) naloxone training programs, due to the novelty of these programs, the evidence of program efficacy is limited. This study describes the implementation and evaluation of a LEO training program in opioid overdose recognition, management, and administration of IN naloxone. METHODS: This evaluation consisted of a secondary analysis of de-identified administrative quality assurance data. Police officers in Howard County, Maryland (n=281) underwent an IN naloxone training program between June and July 2015. The training program entailed a 30-minute online component, a 45-minute in-service session, and a 15-question post-test (n=228). The success of the training program was evaluated via an opioid overdose knowledge survey administered at 30 days (n=207) and 6 months (n=182) after training. RESULTS: The 30-day and 6-month scores for all knowledge outcomes indicated that officers retained the contents of the training program well over time. After six months, 100% of respondents correctly identified the physiological effects of naloxone administration, and 95.6% correctly identified the opioid-containing drugs that may result in overdose. At the six-month mark, 74.59% correctly identified the initial signs of opioid overdose, and 60.99% correctly identified the time required for IN to begin working. CONCLUSION: LEOs exhibit the ability to retain the contents of IN training over 30-day and 6-month periods and express confidence in their ability to assist suspected opioid overdose victims. Further research is necessary to determine the degree to which further knowledge decay might occur, the sustained ability to implement this knowledge under real-world conditions, and the subsequent effects on overdose victim survival.

Implementing a Statewide Prehospital Sepsis Protocol: Perspectives of Emergency Medical Services Medical Directors.

Background Sepsis is a medical emergency that requires prompt recognition and treatment. Multiple Emergency Medical Services (EMS) agencies across the United States have implemented sepsis protocols. In 2016, Maryland instituted its own state-wide EMS sepsis protocol which includes fluid resuscitation, vasopressor administration, and requires alerting the hospital of an incoming sepsis patient. Objective The purpose of this study was to quantify the perspectives of EMS medical directors in Maryland regarding prehospital sepsis care and to identify challenges encountered during the implementation of the statewide sepsis protocol. Methods A 17-question survey was sent to all 24 jurisdictional medical directors in the state of Maryland. Results A total of 14 (58%) medical directors responded, representing four of the five EMS regions in the state. More than half (57%) stated sepsis alerting was a priority in their jurisdiction; however, in a listing of eight initiatives, sepsis was the least prioritized. Most (64%) respondents believed their clinicians had adequate training on sepsis. A majority (79%) of medical directors surveyed felt that core measures of sepsis management would be beneficial. The potentially most helpful core measures were the volume of IV fluid administration (92%), true positive sepsis alerts (83%), and cases of failure to activate a sepsis alert (75%). Engagement of field personnel was rated as the biggest challenge for the implementation of a sepsis protocol in general, and lack of a thermometer on EMS units (50%) was the largest hurdle specifically in the 2016 statewide sepsis protocol. Surveyed medical directors (86%) believe the most difficult obstacle to overcome for EMS clinicians in the treatment of sepsis are nonspecific signs and symptoms. Conclusions Prehospital sepsis care was viewed to be important amongst the medical directors surveyed. However, significant challenges to implementation of a sepsis protocol and delivery of prehospital sepsis care are perceived by jurisdictional medical directors. Additional investment and dedication to sepsis care will advance prehospital sepsis treatment in Maryland.
