Prehospital Supraglottic Airways: An NAEMSP Position Statement and Resource Document.

Supraglottic airway (SGA) devices provide effective conduits for oxygenation and ventilation and may offer protection from gastric aspiration. SGA devices are widely used by EMS clinicians as both rescue and primary airway management devices. While in common use for more than four decades, major developments in SGA education, science, and technology have influenced clinical strategies of SGA insertion and use in prehospital airway management for patients of all ages. NAEMSP recommends:SGAs have utility as a primary or secondary EMS airway intervention. EMS agencies should select SGA strategies that best suit available resources and local clinician skillset, as well as the nature of their clinical practice setting.EMS agencies that perform endotracheal intubation must also equip their clinicians with SGA devices and ensure adequate training and competence.In select situations, drug-assisted airway management may be used by properly credentialed EMS clinicians to facilitate SGA insertion.Confirmation of initial and continuous SGA placement using waveform capnography is strongly encouraged as a best practice.When it is functioning properly, EMS clinicians should refrain from converting an SGA to an endotracheal tube. The decision to convert an SGA to an endotracheal tube must consider the patient's condition, the effectiveness of SGA ventilations, and the clinical context and course of initial SGA insertionSGA training, competency, and clinical use must be continuously evaluated by EMS agencies using focused quality management programs.

Characteristics and Diversity of ACGME Accredited Emergency Medical Services Fellowship Programs.

Introduction: There is a minimal amount of published data regarding to Emergency Medical Services (EMS) fellowship programs. The purpose of this study was to obtain program characteristics and diversity data regarding EMS fellowship programs. Methods: A survey was sent to program directors at all EMS fellowship programs accredited by the Accreditation Council of Graduate Medical Education (ACGME). Data collected included: year program started, year program accredited, unfilled fellow positions, number of EMS faculty, gender, and race/ethnicity. Gender and race/ethnicity data from EMS fellowships were compared to emergency medicine (EM) residencies using data from the American Association of Medical Colleges. Data were analyzed using IBM SPSS with descriptive statistics, and Chi-square tests. Results: The response rate for the survey was 88% (45/51) of all EMS fellowship programs that were accredited at the time of this survey. Most programs (71%) offer a one-year EMS fellowship, with the remaining offering an optional second year. The median number of physician response vehicles per program was 1.0 (IQR 0.0-2.0), with 24% (11/45) not having a dedicated physician response vehicle. This survey identified that 118 EMS fellows have graduated since inception of the accreditation process, while 34 positions went unfilled. The median number of EMS fellow positions per program was 2.0 (IQR 1.0-2.0), with a range of 1 to 4. It was noted that 31% of programs had no female EMS faculty, and 48% of programs had no under-represented minority EMS faculty. There was a significantly larger proportion of female faculty in EM residency programs (30.5%; 949/3,107) compared to EMS fellowships (19%; 53/274), OR = 1.8, 95% CI:1.3-2.5, p < 0.0001. There was a significantly larger proportion of female fellows in EMS (56%; 66/118) vs. female residents in EM (38%; 2,193/5,777), OR" = 2.1, 95% CI:1.4-3.0, p < 0.0001. There was a significantly larger proportion of under-represented minority faculty in EM residency programs (19.7%; 786/3,978) vs. EMS fellowships (12.0%, 33/274), OR = 1.8, 95% CI:1.2-2.6, p < 0.002. Conclusion: A significant number of EMS fellowship positions have remained unfilled since implementation of an accreditation process for EMS fellowships. The percentage of females and under-represented minority faculty in EMS programs was much lower than for EM residency programs.

Comparison Of The I-Gel Supraglottic And King Laryngotracheal Airways In A Simulated Tactical Environment.

BACKGROUND: When working in a tactical environment there are several different airway management options that exist. One published manuscript suggests that when compared to endotracheal intubation, the King LT laryngotracheal airway (KA) device minimizes time to successful tube placement and minimizes exposure in a tactical environment. However, comparison of two different blind insertion supraglottic airway devices in a tactical environment has not been performed. This study compared the I-Gel airway (IGA) to the KA in a simulated tactical environment, to determine if one device is superior in minimizing exposure and minimizing time to successful tube placement. METHODS: This prospective randomized cross over trial was performed using the same methods and tactical environment employed in a previously published study, which compared endotracheal intubation versus the KA in a tactical environment. The tactical environment was simulated with a one-foot vertical barrier. The participants were paramedic students who wore an Advanced Combat Helmet (ACH) and a ballistic vest (IIIA) during the study. Participants were then randomized to perform tactical airway management on an airway manikin with either the KA or the IGA, and then again using the alternate device. The participants performed a low military type crawl and remained in this low position during each tube placement. We evaluated the time to successful tube placement between the IGA and KA. During attempts, participants were videotaped to monitor their height exposure above the barrier. Following completion, participants were asked which airway device they preferred. Data was analyzed using Student's t-test across the groups for time to ventilation and height of exposure. RESULTS: In total 19 paramedic students who were already at the basic EMT level participated. Time to successful placement for the KA was 39.7 seconds (95%CI: 32.7-46.7) versus 14.4 seconds (95%CI: 12.0-16.9) for the IGA, p < 0.001. Maximum height exposure of the helmet above a one foot vertical barrier for the KA resulted in 1.42 inches of exposure (95%CI: 0.38-0.63) compared to the IGA with 1.42 inches, 95%CI:0.32-0.74, p = 0.99. On questioning 100% of the participants preferred the IGA device over the KA. CONCLUSION: In a simulated tactical environment placement of the IGA for airway management was faster than with the KA, but there was no difference in regard to exposure. Additionally, all the participants preferred using the IGA device over the KA.

Prehospital care of traumatic brain injury in North Carolina.

Traumatic brain injury results in more than 140,000 visits to North Carolina emergency departments annually. North Carolina first implemented a systematically organized approach to brain injury management in 1967, and the state's emergency medical services community continues to optimize patient care by incorporating evolving knowledge into protocols and procedures.

North Carolina College of Emergency Physicians' Guidance Document on Emergency Medical Services.

The North Carolina College of Emergency Physicians (NCCEP) Emergency Medical Services (EMS) Committee uses an evidence-based approach in writing its protocols and procedures. The most recent revision of the NCCEP document, which was started in late 2010, lasted for more than 1 year and utilized committee members from across the state. Four meetings were held at locations across North Carolina. In addition, 2 surveys were sent to get input from EMS providers. Since 2010, the document has been updated on an ongoing basis, aligning it with the latest evidence-based medicine.

Emergency medical services education research priorities during COVID-19: A modified Delphi study.

OBJECTIVE: Our objective was to identify research priorities to understand the impact of COVID-19 on initial emergency medical services (EMS) education. METHODS: We used a modified Delphi method with an expert panel (n = 15) of EMS stakeholders to develop consensus on the research priorities that are most important and feasible to understand the impact of the COVID-19 pandemic on initial EMS education. Data were collected from August 2020 to February 2021 over 5 rounds (3 electronic surveys and 2 live virtual meetings). In Round 1, participants submitted research priorities over 9 specific areas. Responses were thematically analyzed to develop a list of research priorities reviewed in Round 2. In Round 3, participants rated the priorities by importance and feasibility, with a weighted score (2/3*importance+1/3*feasibility) used for preliminary prioritization. In Round 4, participants ranked the priorities. In Round 5, participants provided their agreement or disagreement with the group's consensus of the top 8 research priorities. RESULTS: During Rounds 1 and 2, 135 ideas were submitted by the panel, leading to a preliminary list of 27 research priorities after thematic analysis. The top 4 research priorities identified by the expert panel were prehospital internship access, impact of lack of field and clinical experience, student health and safety, and EMS education program availability and accessibility. Consensus was reached with 10/11 (91%) participants in Round 5 agreeing. CONCLUSIONS: The identified research priorities are an important first step to begin evaluating the EMS educational infrastructure, processes, and outcomes that were affected or threatened through the pandemic.

Willingness of Emergency Medical Services Professionals to Respond to an Active Shooter Incident.

BACKGROUND: Historically, staging of civilian emergency medical services (EMS) during an active shooter incident was in the cold zone while these professionals awaited the scene to be completely secured by multiple waves of law enforcement. This delay in EMS response has led to the development of a more effective method: the Rescue Task Force (RTF). The RTF concept has the second wave of law enforcement escorting civilian EMS into the warm zone, thus decreasing EMS response time. To our knowledge, there are no data regarding the willingness of EMS professionals to enter a warm zone as part of an RTF. In this study, we assessed the willingness of EMS providers to respond to an active shooter incident as part of an RTF. METHODS: A survey was distributed at an annual, educational EMS conference in North Carolina. The surveys were distributed on the first day of the conference at the beginning of a general session that focused on EMS stress and wellness. Total attendance was measured using identification badges and scanners on exiting the session. Data were assessed using χ2 analysis, as were associations between demographics of interest and willingness to respond under certain conditions. A p value < .01 indicated statistical significance. RESULTS: The overall response rate was 76% (n = 391 of 515 session attendees). Most surveys were completed by paramedics (74%; n = 288 of 391). Most EMS professionals (75%; n = 293 of 391) stated they would respond to the given active shooter scenario as part of an RTF (escorted by the second wave of law enforcement) if they were given only ballistic gear. However, most EMS professionals (61%; n = 239 of 391) stated they would not respond if they were provided no ballistic gear and no firearm. Those with tactical or military training were more willing to respond with no ballistic gear and no firearm (49.6%; n = 68 of 137) versus those without such training (31%; n = 79 of 250; odds ratio, 2.2; 95% confidence interval, 1.4-3.3; p < .001). CONCLUSION: EMS professionals are willing to put themselves in harm's way by entering a warm zone if they are simply provided the proper training and ballistic equipment.

Motor vehicle crash fatalities among Hispanics in rural North Carolina.

OBJECTIVES: Deaths from motor vehicle crashes (MVCs) have decreased significantly over the past three decades. Unfortunately, few data have been collected regarding death rates for MVCs in minority populations. The purpose of this study was to compare the death rate of whites versus Hispanics for MVCs in a rural environment. METHODS: This study examined one rural county in North Carolina from January 1, 1999, to December 31, 1999. A retrospective cohort study was performed using the North Carolina State Highway Patrol computerized database of MVCs. Data regarding the total number of MVCs, fatalities, alcohol-related deaths, seatbelt usage, and cause of the collision were analyzed for both whites and Hispanics. Census information regarding population in this region also was obtained from the U.S. Bureau of Census. Data were analyzed using a chi-square test, with an alpha value of 0.05 used to establish statistical significance. RESULTS: During the study period, whites were involved in 2,689 MVCs, compared with 158 MVCs for Hispanics. Whites were involved in ten fatal MVCs, compared with seven fatal MVCs involving Hispanics. The percent of fatal MVCs for whites was 0.3%, or 10 deaths per 2,689 MVCs. In contrast, the percent of fatal MVCs for Hispanics was 4.4%, or 7 deaths per 158 MVCs; odds ratio (OR) = 12.4, 95% CI = 4.7 to 33.1. The 2000 Census Report for Pitt County noted a white population of 81,613 and a Hispanic population of 4,216. Based on these population data, the death rate for MVCs per 100,000 population was 12.3 for whites versus 166.0 for Hispanics, OR = 13.6, 95% CI = 5.2 to 35.6. Although the cause for this disparity was not determined, previous studies suggest that alcohol and decreased seatbelt usage are contributing factors. CONCLUSIONS: In this study, the death rates among Hispanics for rural MVCs were significantly higher than for whites. The causes of this disparity are not clear but are important to define. Only by understanding this disparity can we begin to develop appropriate interventions that may prevent these deaths.

Changes in physical examination caused by use of spinal immobilization.

UNLABELLED: The standard of care for patients following blunt trauma includes midline palpation of vertebrae to rule out fractures. Previous studies have demonstrated that spinal immobilization does cause discomfort. OBJECTIVE: To determine whether spinal immobilization causes changes in physical exam findings over time. METHODS: This was a single-blinded, prospective study at a tertiary care university teaching hospital. Twenty healthy volunteers without previous back pain or injuries, 13 male and seven female, were fully immobilized for one hour, with a cervical collar and strapped to a long wooden backboard. Midline palpation of vertebrae to illicit pain was performed at 10-minute intervals. In addition, the participants were asked to rate neck and back pain on a scale from 1 to 10 (1 for no pain, and 10 for unbearable pain), to see whether subjective pain from immobilization correlated with tenderness to palpation. RESULTS: Three patients had point tenderness of cervical vertebrae within 40 minutes. Five patients developed point tenderness of vertebrae by 60 minutes. Eighteen of 20 participants complained of increasing discomfort over time. The median initial pain scale was 1 (range 1-1), in contrast to 4 (range 1-9) at 60 minutes, p < 0.05. CONCLUSION: This study shows that over time, standard immobilization causes a false-positive exam for midline vertebral tenderness. In order to reduce this high false-positive rate for midline vertebral tenderness, the authors recommend that, initially on arrival to the emergency department, immediate evaluation occur of all immobilized patients. Furthermore, backboards should be modified to reduce patient discomfort to prevent the iatrogenically induced midline vertebral tenderness, thereby reducing subsequent false-positive examinations.

National prevalence of palliative care protocols in emergency medical services.

OBJECTIVES: There are approximately 500,000 hospice patients in the United States. While hospice patients may desire only palliative care, they often access the emergency medical services (EMS) system, unaware that many EMS systems do not have specific palliative care protocols. This study was undertaken to determine the prevalence of palliative care protocols among EMS agencies in the United States, and to estimate the percentage of the U.S. population covered by such protocols. METHODS: A survey requesting information about out-of-hospital palliative care protocols was mailed to the EMS agencies serving the 200 most populous U.S. cities. After four weeks a follow-up telephone call was made to those agencies that had not yet responded. The number of agencies with a palliative care protocol was determined, and the populations served by those agencies with and without palliative care protocols were calculated. RESULTS: Responses were received from 121 (60.5%) of the cities. Only seven (5.8%) of the responding cities' EMS agencies had a palliative care protocol. The population of cities covered by a palliative care protocol was just under 3 million, or slightly more than 6% of the 47.2 million people living in the responding cities. CONCLUSIONS: Most of the U.S. population is not served by an EMS agency with specific palliative care protocols. Until more EMS systems enact specific palliative care protocols, physicians treating the terminally ill should educate patients and families about appropriate use of the EMS system, and that EMS professionals may be required to provide more than supportive care.
