RESUMEN
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.

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 (â¼1 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.
RESUMEN
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.
RESUMEN
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.

CONTEXT: Emergency medical services (EMS) medicine continues to expand and mature as a recognized subspeciality within emergency medicine. In the United States, EMS physicians historically supported training, protocol development, and EMS clinician credentialing. In the past, only limited programs existed in which prehospital physicians were engaged in the direct and routine care of prehospital patients; however, a growing number of EMS programs are recognizing the value and impact of direct EMS physician involvement in prehospital patient care. PROGRAM: A large suburban, volunteer-based EMS agency implemented a volunteer prehospital physician program where providers routinely responded to emergency calls for service. IMPLEMENTATION: Beginning in November 2019, a cadre of board-certified physicians completed a field preceptorship and local protocol orientation. Once complete, the physicians were released to function and respond independently to high acuity emergency calls or any call at their discretion. Prehospital physicians were authorized to utilize their full scope of practice and expected to provide field mentorship to traditional prehospital clinicians. EVALUATION: This study systematically evaluated a prehospital physician program for public health relevance, sustainability, and population health impact using the RE-AIM framework. A retrospective descriptive analysis was performed on the role and responses by a cohort of prehospital physicians using dispatch data and electronic medical records. DISCUSSION: Over the 17-month study period, 9 prehospital physicians responded to 482 calls, predominately cardiac arrests, traumatic injuries, and cardiac/chest pain. The physicians performed 99 procedures and administered 113 medications. Ultimately, the program added physician-level care to the prehospital setting in an ongoing and sustainable way. The routine placement of physicians in the prehospital environment can help benefit patients by enhancing access to advanced clinical knowledge and skills, while also benefiting EMS clinicians through opportunities for enhanced patient-side training, education, and medical control.

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.
RESUMEN
Traumatic injuries remain the leading cause of death for those under the age of 44 years old. Nearly a third of those who die from trauma do so from bleeding. Reducing death from severe bleeding requires training in the recognition and treatment of life-threatening bleeding, as well as programs to ensure immediate access to bleeding control resources. The Stop the Bleed (STB) initiative seeks to educate and empower people to be immediate responders and provide control of life-threatening bleeding until emergency medical services arrive. Well-planned and implemented STB programs will help ensure program effectiveness, minimize variability, and provide long-term sustainment. Comprehensive STB programs foster consistency, promote access to bleeding control education, contain a framework to guide the acquisition and placement of equipment, and promote the use of these resources at the time of a bleeding emergency. We leveraged the expertise and experience of the Stop the Bleed Education Consortium to create a resource document to help inform and guide STB program developers and implementers on the key areas for consideration when crafting strategy. These areas include (1) equipment selection, (2) logistics and kit placement, (3) educational program accessibility and implementation, and (4) program oversight, facilitation, and administration.
RESUMEN
The transformation of synaptic input into action potential output is a fundamental single-cell computation resulting from the complex interaction of distinct cellular morphology and the unique expression profile of ion channels that define the cellular phenotype. Experimental studies aimed at uncovering the mechanisms of the transfer function have led to important insights, yet are limited in scope by technical feasibility, making biophysical simulations an attractive complementary approach to push the boundaries in our understanding of cellular computation. Here we take a data-driven approach by utilizing high-resolution morphological reconstructions and patch-clamp electrophysiology data together with a multi-objective optimization algorithm to build two populations of biophysically detailed models of murine hippocampal CA3 pyramidal neurons based on the two principal cell types that comprise this region. We evaluated the performance of these models and find that our approach quantitatively matches the cell type-specific firing phenotypes and recapitulate the intrinsic population-level variability in the data. Moreover, we confirm that the conductance values found by the optimization algorithm are consistent with differentially expressed ion channel genes in single-cell transcriptomic data for the two cell types. We then use these models to investigate the cell type-specific biophysical properties involved in the generation of complex-spiking output driven by synaptic input through an information-theoretic treatment of their respective transfer functions. Our simulations identify a host of cell type-specific biophysical mechanisms that define the morpho-functional phenotype to shape the cellular transfer function and place these findings in the context of a role for bursting in CA3 recurrent network synchronization dynamics.

In the context of an on-going global pandemic that has demanded increasingly more of our Emergency Medical Services (EMS) clinicians, the health humanities can function to aid in educational training, promoting resilience and wellness, and allowing opportunity for self-expression to help prevent vicarious trauma.As the social, cultural, and political landscape of the United States continues to require an expanded scope of practice from our EMS clinicians, it is critical that the health humanities are implemented as not only part of EMS training, but also as part of continued practice in order to ensure the highest quality patient-centered care while protecting the longevity and resilience of EMS clinicians.
RESUMEN
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.

OBJECTIVE: Influenza vaccination remains the most effective primary prevention strategy for seasonal influenza. This research explores the percentage of emergency medical services (EMS) clinicians who received the seasonal flu vaccine in a given year, along with their reasons for vaccine acceptance and potential barriers. METHODS: A survey was distributed to all EMS clinicians in Virginia during the 2018-2019 influenza season. The primary outcome was vaccination status. Secondary outcomes were attitudes and perceptions toward influenza vaccination, along with patient care behaviors when treating an influenza patient. RESULTS: Ultimately, 2796 EMS clinicians throughout Virginia completed the survey sufficiently for analysis. Participants were mean 43.5 y old, 60.7% male, and included the full range of certifications. Overall, 79.4% of surveyed EMS clinicians received a seasonal flu vaccine, 74% had previously had the flu, and 18% subjectively reported previous side effects from the flu vaccine. Overall, 54% of respondents believed their agency has influenza or respiratory specific plans or procedures. CONCLUSIONS: In a large, state-wide survey of EMS clinicians, overall influenza vaccination coverage was 79.4%. Understanding the underlying beliefs of EMS clinicians remains a critical priority for protecting these frontline clinicians. Agencies should consider practical policies, such as on-duty vaccination, to increase uptake.

INTRODUCTION: Ambulance patients who are unable to be quickly transferred to an emergency department (ED) bed represent a key contributing factor to ambulance offload delay (AOD). Emergency department crowding and associated AOD are exacerbated by multiple factors, including infectious disease outbreaks such as the coronavirus disease 2019 (COVID-19) pandemic. Initiatives to address AOD present an opportunity to streamline ambulance offload procedures while improving patient outcomes. STUDY OBJECTIVE: The goal of this study was to evaluate the initial outcomes and impact of a novel Emergency Medical Service (EMS)-based Hospital Liaison Program (HLP) on ambulance offload times (AOTs). METHODS: Ambulance offload times associated with EMS patients transported to a community hospital six months before and after HLP implementation were retrospectively analyzed using proportional significance tests, t-tests, and multiple regression analysis. RESULTS: A proportional increase in incidents in the zero to <30 minutes time category after program implementation (+2.96%; P <.01) and a commensurate decrease in the proportion of incidents in the 30 to <60 minutes category (-2.65%; P <.01) were seen. The fully adjusted regression model showed AOT was 16.31% lower (P <.001) after HLP program implementation, holding all other variables constant. CONCLUSION: The HLP is an innovative initiative that constitutes a novel pathway for EMS and hospital systems to synergistically enhance ambulance offload procedures. The greatest effect was demonstrated in patients exhibiting potentially life-threatening symptoms, with a reduction of approximately three minutes. While small, this outcome was a statistically significant decrease from the pre-intervention period. Ultimately, the HLP represents an additional strategy to complement existing approaches to mitigate AOD.

Decisions for patient transport by emergency medical services (EMS) are individualized; while established guidelines help direct adult patients to specialty hospitals, no such pediatric equivalents are in wide use. When children are transported to a hospital that cannot provide definitive care, care is delayed and may cause adverse events. Therefore, we created a novel evidence-based decision tool to support EMS destination choice. A multidisciplinary expert panel (EP) of stakeholders reviewed published literature. Four facility capability levels for pediatric care were defined. Using a modified Delphi method, the EP matched specific conditions to a facility pediatric-capability level in a draft tool. The literature review and EP recommendations identified seventeen pediatric medical conditions at risk for secondary transport. In the first voting round, two were rejected, nine met consensus for a specific facility capability level, and six did not reach consensus on the destination facility level. A second round reached consensus on a facility level for the six conditions as well as revision of one previously rejected condition. In the third round, the panel selected a visual display format. Finally, the panel unanimously approved the PDTree. Using a modified Delphi technique, we developed the PDTree EMS destination decision tool by incorporating existing evidence and the expertise of a multidisciplinary panel.
RESUMEN
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.

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.

Background Animal attacks pose a significant public health problem in the United States. Non-venomous animals are the leading cause of mortality in these attacks, and extremity injuries leading to hemorrhage are a common pattern. The Stop the Bleed campaign advocates for public training in bleeding control tactics and public access to bleeding control kits. Controlling life-threatening bleeding, as promoted by the Stop the Bleed campaign, may be a method to reduce preventable death in these attacks. Methodology We searched the Nexus Uni database, which compiles international news media articles, to collect newspaper articles in the United States between 2010 and 2019 that referenced animal attacks on humans in which a tourniquet was applied. We screened articles to assess for inclusion criteria and isolated a single report for each attack. Results A total of 50 individual attacks met the inclusion criteria and were included for data collection. Overall, 92% (n = 46) of the victims survived the attacks, and the average victim age was 33. California was the most common location of the attacks (n = 12, 24%), sharks caused the most attacks (n = 26, 52%), and victims most often sustained isolated extremity injuries (n = 24, 48% for arm and n = 24, 48% for leg). Laypeople applied the most tourniquets (n = 29, 58%), and appliers most frequently used improvised tourniquets (n = 30, 60%). Conclusions While mortality in this series was low, there are hundreds of fatalities from non-venomous animal attacks each year. Equipping and training the at-risk public to stop bleeding may save additional lives. Future Stop the Bleed efforts should improve access to public hemorrhage control equipment and expand educational outreach to people engaged in high-risk activities with animals.
RESUMEN
BACKGROUND: The Stop the Bleed (STB) campaign was developed in part to educate the lay public about hemorrhage control techniques aimed at reducing preventable trauma deaths. Studies have shown this training increases bystanders' confidence and willingness to provide aid. One high-risk group might be better solicited to take the course: individuals who have been a victim of previous trauma, as high rates of recidivism after trauma are well-established. Given this group's risk for recurrent injury, we evaluated their attitudes toward STB concepts. METHODS: We surveyed trauma patients admitted to 3 urban trauma centers in Baltimore from January 8, 2020 to March 14, 2020. The survey was terminated prematurely due to the COVID-19 pandemic. Trauma patients hospitalized on any inpatient unit were invited to complete the survey via an electronic tablet. The survey asked about demographics, prior exposure to life-threatening hemorrhage and first aid training, and willingness to help a person with major bleeding. The Johns Hopkins IRB approved waiver of consent for this study. RESULTS: Fifty-six patients completed the survey. The majority of respondents had been hospitalized before (92.9%) and had witnessed severe bleeding (60.7%). The majority had never taken a first aid course (60.7%) nor heard of STB (83.9%). Most respondents would be willing to help someone with severe bleeding form a car crash (98.2%) or gunshot wound (94.6%). CONCLUSIONS: Most patients admitted for trauma had not heard about Stop the Bleed, but stated willingness to respond to someone injured with major bleeding. Focusing STB education on individuals at high-risk for trauma recidivism may be particularly effective in spreading the message and skills of STB.

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.
