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.
Palmer amaranth (Amaranthus palmeri S. Watson) is the most problematic weed of cotton (Gossypium hirsutum L.)-cropping systems in the U.S. Southeast. Heavy reliance on herbicides has selected for resistance to multiple herbicide mechanisms of action. Effective management of this weed may require the integration of cultural practices that limit germination, establishment, and growth. Cover crops have been promoted as a cultural practice that targets these processes. We conducted a 2-yr study in Georgia, USA, to measure the effects of two annual cover crops (cereal rye [Secale cereale L.] and crimson clover [Trifolium incarnatum L.]), a perennial living mulch (‘Durana®’ white clover [Trifolium repens L.]), and a bare ground control on A. palmeri population dynamics. The study was conducted in the absence of herbicides. Growth stages were integrated into a basic demographic model to evaluate differences in population trajectories. Cereal rye and living mulch treatments suppressed weed seedling recruitment (seedlings seed−1) 19.2 and 13 times and 12 and 25 times more than the bare ground control, respectively. Low recruitment was correlated positively with low light transmission (photosynthetic active radiation: above canopy photosynthetically active radiation [PAR]/below cover crop PAR) at the soil surface. Low recruitment rates were also negatively correlated with high survival rates. Greater survival rates and reduced adult plant densities resulted in greater biomass (g plant−1) and fecundity (seeds plant−1) in cereal rye and living mulch treatments in both years. The annual rate of population change (seeds seed−1) was equivalent across all treatments in the first year but was greater in the living mulch treatment in the second year. Our results highlight the potential of annual cover crops and living mulches for suppressing A. palmeri seedling recruitment and would be valuable tools as part of an integrated weed management strategy.
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.
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.
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.
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.
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.
Archaeologists have a responsibility to use their research to engage people and provide opportunities for the public to interact with cultural heritage and interpret it on their own terms. This can be done through hypermedia and deep mapping as approaches to public archaeology. In twenty-first-century archaeology, scholars can rely on vastly improved technologies to aid them in these efforts toward public engagement, including digital photography, geographic information systems, and three-dimensional models. These technologies, even when collected for analysis or documentation, can be valuable tools for educating and involving the public with archaeological methods and how these methods help archaeologists learn about the past. Ultimately, academic storytelling can benefit from making archaeological results and methods accessible and engaging for stakeholders and the general public. ArcGIS StoryMaps is an effective tool for integrating digital datasets into an accessible framework that is suitable for interactive public engagement. This article describes the benefits of using ArcGIS StoryMaps for hypermedia and deep mapping–based public engagement using the story of copper production in Iron Age Faynan, Jordan, as a case study.
What do Americans want from immigration policy and why? In the rise of a polarized and acrimonious immigration debate, leading accounts see racial anxieties and disputes over the meaning of American nationhood coming to a head. The resurgence of parochial identities has breathed new life into old worries about the vulnerability of the American Creed. This book tells a different story, one in which creedal values remain hard at work in shaping ordinary Americans' judgements about immigration. Levy and Wright show that perceptions of civic fairness - based on multiple, often competing values deeply rooted in the country's political culture - are the dominant guideposts by which most Americans navigate immigration controversies most of the time and explain why so many Americans simultaneously hold a mix of pro-immigrant and anti-immigrant positions. The authors test the relevance and force of the theory over time and across issue domains.
Stephen Hawking’s A Brief History of Time1 begins with a famous anecdote about a “little old lady” who challenges a scientist’s public lecture on astronomy, insisting that in fact the earth is flat and rests on the back of a giant tortoise. When the scientist asks what holds the tortoise in its place, the lady is ready for him: “You’re very clever, young man, very clever … but it’s turtles all the way down!” Too often, it seems to us, both the guiding assumption and core insight of sociopsychological accounts of mass opinion is that “it’s groups all the way down.”
There is little doubt that, in the abstract, Americans are wary about the number of immigrants coming into the United States.1 Gallup began asking in 1965 whether the level of immigration should be increased, decreased, or kept the same. For most of the last half century, support for increasing immigration hovered in the single digits or low teens. As of 2019, it has never exceeded 30%.2 Wariness about rising levels of immigration is evident even when surveys clarify that they are asking about legal rather than illegal immigration, a distinction to which we return at length in Chapter 4. For example, a Fox News3 poll conducted in April 2013 asked a national sample “Do you think the United States should increase or decrease the number of LEGAL immigrants allowed to move to this country?” The majority, 55%, said the number should be decreased, compared to 28% who said it should be increased, with 10% volunteering that the number should not be change and 7% unsure. These numbers were little changed from earlier polls conducted in 2007 and 2010, though other time series do show marked increases in support for preserving and even increasing legal admissions in the last several years.4 Despite recent rises in public support for increasing immigration and drops in support for decreasing it, Peter Schuck’s pithy phrase remains true of a broad cross-section of the public: “Americans do not oppose immigration in principle, in general, or unalterably, but they do want less of it (or at least no higher).”5
In this chapter, we develop a framework for understanding how Americans’ opinions about immigration policy issues emerge from their conceptions of civic fairness. We then review leading theories of immigration attitudes that are premised on group-centrism, with an eye to considering (1) what questions they leave open about the relative influence of considerations rooted in political values and group allegiances and animosities, (2) what challenges they pose to the civic fairness framework, and (3) where they lay claim to empirical phenomena that could also be explained by conceptions of civic fairness. Finally, from this discussion we derive several hypotheses that guide the empirical tests in the chapters that follow. These hypotheses apply to situations where values collide with group loyalties to race and nation, which is to say instances in which the civic fairness and group-centrist perspectives make distinct predictions about what immigration policy alternatives Americans will choose.
What does a nation of immigrants want from its immigration policy, and why? The evidence from decades of public polling defies simple answers. Scholars and journalists reflexively label people as “pro-immigrant” or “anti-immigrant” and seek to situate them along a spectrum running between these two poles. But most Americans hold seemingly idiosyncratic mixes of “pro-” and “anti-immigrant” opinions across the range of controversies that make up contemporary immigration debates. Their opinions about specific policies routinely deviate from their more general feelings about immigrants and immigration and confound familiar explanations based on “economic” or “cultural” threat. Their views about different facets of immigration policy diverge to the point that the great majority of Americans at once endorse some policies that would greatly expand immigrant admissions and rights and others that would sharply curtail them.
