Introduction: The out-of-hospital emergency medical service (EMS) care responses and the transport pathways to hospital play a vital role in patient survival following injury and are the first component of a well-functioning, optimised system of trauma care. Despite longstanding challenges in delivering equitable healthcare services in the health system of Aotearoa-New Zealand (NZ), little is known about inequities in EMS-delivered care and transport pathways to hospital-level care.

Methods: This population-level cohort study on out-of-hospital care, based on national EMS data, included trauma patients <85 years in age who were injured in a road traffic crash (RTC). In this study we examined the combined relationship between ethnicity and geographical location of injury in EMS out-of-hospital care and transport pathways following RTCs in Aotearoa-NZ. Analyses were stratified by geographical location of injury (rural and urban) and combined ethnicity-geographical location (rural Māori, rural non-Māori, urban Māori, and urban non-Māori).

Results: In a two-year period, there were 746 eligible patients; of these, 692 were transported to hospital. Indigenous Māori comprised 28% (196) of vehicle occupants attended by EMS, while 47% (324) of patients' injuries occurred in a rural location. The EMS transport pathways to hospital for rural patients were slower to reach first hospital (total in slowest tertile of time 44% vs 7%, P ≥ 0.001) and longer to reach definitive care (direct transport, 77% vs 87%, P = 0.001) compared to urban patients. Māori patients injured in a rural location were comparatively less likely than rural non-Māori to be triaged to priority transport pathways (fastest dispatch triage, 92% vs 97%, respectively, P = 0.05); slower to reach first hospital (total in slowest tertile of time, 55% vs 41%, P = 0.02); and had less access to specialist trauma care (reached tertiary trauma hospital, 51% vs 73%, P = 0.02).

Conclusion: Among RTC patients attended and transported by EMS in NZ, there was variability in out-of-hospital EMS transport pathways through to specialist trauma care, strongly patterned by location of incident and ethnicity. These findings, mirroring other health disparities for Māori, provide an equity-focused evidence base to guide clinical and policy decision makers to optimize the delivery of EMS care and reduce disparities associated with out-of-hospital EMS care.

Introduction: People who use drugs in community settings are at risk of a fatal overdose, which can be mitigated by naloxone administered via bystanders. In this study we sought to investigate methods of estimating and tracking opioid overdose reversals by community members with take-home naloxone (THN) to coalesce possible ways of characterizing THN reach with a metric that is useful for guiding both distribution of naloxone and advocacy of its benefits.

Methods: We conducted a scoping review of published literature on PubMed on August 15, 2022, using PRISMA-ScR protocol, for articles discussing methods to estimate THN reversals in the community. The following search terms were used: naloxone AND ("take home" OR kit OR "community distribution" OR "naloxone distribution"). We used backwards citation searching to potentially find additional studies. Overdose education and naloxone distribution program-based studies that analyzed only single programs were excluded.

Results: The database search captured 614 studies, of which 14 studies were relevant. Backwards citation searching of 765 references did not reveal additional relevant studies. Of the 14 relevant studies, 11 were mathematical models. Ten used Markov models, and one used a system dynamics model. Of the remaining three articles, one was a meta-analysis, and two used spatial analysis. Studies ranged in year of publication from 2013-2022 with mathematical modeling increasing in use over time. Only spatial analysis was used with a focus on characterizing local naloxone use at the level of a specific city.

Conclusion: Of existing methods to estimate bystander administration of THN, mathematical models are most common, particularly Markov models. System dynamics modeling, meta-analysis, and spatial analysis have also been used. All methods are heavily dependent upon overdose education and naloxone distribution program data published in the literature or available as ongoing surveillance data. Overall, there is a paucity of literature describing methods of estimation and even fewer with methods applied to a local focus that would allow for more targeted distribution of naloxone.

Introduction: In this study we aimed to investigate the effects of incorporating Swedish-style fika (coffee) breaks into the didactic schedule of emergency medicine residents on their sleepiness levels during didactic sessions. Fika is a Swedish tradition that involves a deliberate decision to take a break during the workday and usually involves pastries and coffee. We used the Karolinska Sleepiness Scale to assess changes in sleepiness levels before and after the implementation of fika breaks.

Methods: The study design involved a randomized crossover trial approach, with data collected from emergency medicine residents over a specific period. This approach was done to minimize confounding and to be statistically efficient.

Results: Results revealed the average sleepiness scale was 4.6 and 5.5 on fika and control days, respectively (P = 0.004).

Conclusion: Integration of fika breaks positively influenced sleepiness levels, thus potentially enhancing the educational experience during residency didactics.

Introduction: The seemingly inexorable rise of opioid-related overdose deaths despite the reduced number of COVID-19 pandemic deaths demands novel responses and partnerships in our public health system's response. Addiction medicine is practiced in a broad range of siloed clinical environments that need to be included in addiction medicine training beyond the traditional fellowship programs. Our objective in this project was to implement a knowledge-based, live virtual training program that would provide clinicians and other healthcare professionals with an overview of addiction, substance use disorders (SUD), and clinical diagnosis and management of opioid use disorder (OUD).

Methods: The Veterans Health Administration (VHA) Emergency Department Opioid Safety Initiative (ED OSI) offered a four-day course for healthcare professionals interested in gaining knowledge and practical skills to improve VHA-based SUD care. The course topics centered around the diagnosis and treatment of SUD, with a focus on OUD. Additionally, trainees received six months of support to develop addiction medicine treatment programs. Evaluations of the course were performed immediately after completion of the program and again at the six-month mark to assess its effectiveness.

Results: A total of 56 clinicians and other healthcare professionals participated in the Addiction Scholars Program (ASP). The participants represented nine Veteran Integrated Service Networks and 21 different VHA medical facilities. Nearly 70% of participants completed the initial post-survey. Thirty-eight respondents (97.4%) felt the ASP series contained practical examples and useful information that could be applied in their work. Thirty-eight respondents (97.4%) felt the workshop series provided new information or insights into the diagnosis and treatment of SUD. Eleven capstone projects based on the information acquired during the ASP were funded (a total of $407,178). Twenty participants (35.7%) completed the six-month follow-up survey. Notably, 90% of respondents reported increased naloxone prescribing and 50% reported increased prescribing of buprenorphine to treat patients with OUD since completing the course.

Conclusion: The ASP provided healthcare professionals with insight into managing SUD and equipped them with practical clinical skills. The students translated the information from the course to develop medication for opioid use disorder (M-OUD) programs at their home institutions.

Introduction: Situational awareness is essential during emergent procedures such as endotracheal intubation. Previous studies suggest that time distortion can occur during intubation. However, only in-hospital intubations performed by physicians have been studied. We aimed to determine whether time distortion affected paramedics performing intubation by examining the perceived vs actual total laryngoscopy time, defined as time elapsed from the laryngoscope blade entering the mouth until the endotracheal tube balloon passes the vocal cords.

Methods: For this retrospective study we collected prehospital intubation data from a suburban, fire department-based emergency medical services (EMS) system from January 5, 2021-May 21, 2022. The perceived total laryngoscopy time was queried as a part of the electronic health record. Video laryngoscopy recordings were reviewed by a panel of experts to determine the actual time. Patients >18 years old who underwent intubation by paramedics with video laryngoscopy were included for analysis. The primary outcome was the difference between actual and perceived total laryngoscopy time. Secondary analysis examined the relationship between high time distortion, defined as the highest quartile of the primary outcome, and patient age, paramedic years of experience, perceived presence of difficult anatomy, excess secretions, use of rapid sequence intubation, and multiple intubation attempts. We conducted descriptive analysis followed by logistic regression analysis, chi-square tests, and Fisher exact tests when appropriate.

Results: A total of 122 intubations were collected for analysis, and 10 were excluded due to lack of video recording. Final analysis included 112 intubations. Mean actual laryngoscopy time was 50.0 seconds (s) (95% confidence interval [CI] 43.7-56.3). Mean perceived laryngoscopy time was 27.8 s (95% CI 24.7-31.0). The median difference between actual and perceived time was 18 s (interquartile range 6-30). We calculated high time distortion as having a difference greater than 30 s between actual and perceived laryngoscopy time. None of the secondary variables had statistically significant associations with high time distortion. Overall, we show that the paramedic's perception of total laryngoscopy time is significantly underestimated even when accounting for paramedic experience and perceived airway difficulty.

Conclusion: This study suggests that time distortion may lead to an unrecognized prolonged procedure time. Limitations include use of a convenience sample, small sample size, and potential uncollected confounding variables.

Introduction: Initiation of buprenorphine for opioid use disorder (OUD) in the emergency department (ED) is supported by the American College of Emergency Physicians and is shown to be beneficial. This practice, however, is largely underutilized.

Methods: To assess emergency clinicians' attitudes and readiness to initiate buprenorphine in the ED we conducted a cross-sectional, electronic survey of clinicians (attendings, residents, and non-physician clinicians) in a single, academic ED of a tertiary-care hospital, which serves a rural population. Our survey aimed to assess emergency clinicians' attitudes toward and readiness to initiate buprenorphine in the ED and identify clinician-perceived facilitators and barriers. Our survey took place after the initiation of the IMPACT (Initiation of Medication, Peer Access, and Connection to Treatment) project.

Results: Our results demonstrated the level of agreement that buprenorphine prescribing is within the emergency clinician's scope of practice was inversely correlated to average years in practice (R² = 0.93). X-waivered clinicians indicated feeling more prepared to administer buprenorphine in the ED R² = 0.93. However, they were not more likely to report ordering buprenorphine or naloxone in the ED within the prior three months. Those who reported having a family member or close friend with substance use disorder (SUD) were not more likely to agree buprenorphine initiation is within the clinician's scope of practice (P = 0.91), nor were they more likely to obtain an X-waiver (P = 0.58) or report ordering buprenorphine or naloxone for patients in the ED within the prior three months (P = 0.65, P = 0.77). Clinicians identified availability of pharmacists, inpatient/outpatient referral resources, and support staff (peer recovery support specialists and care managers) as primary facilitators to buprenorphine initiation. Inability to ensure follow-up, lack of knowledge of available resources, and insufficient education/preparedness were primary barriers to ED buprenorphine initiation. Eighty-three percent of clinicians indicated they would be interested in additional education regarding OUD treatment.

Conclusion: Our data suggests that newer generations of emergency clinicians may have less hesitancy initiating buprenorphine in the ED. In time, this could mean increased access to treatment for patients with OUD. Understanding clinician-perceived facilitators and barriers to buprenorphine initiation allows for better resource allocation. Clinicians would likely further benefit from additional education regarding medications for opioid use disorder (MOUD), available resources, and follow-up statistics.

Introduction: Standard of care for patients with acute ischemic stroke from large vessel occlusion (AIS-LVO) includes prompt evaluation for urgent mechanical thrombectomy (MT) at a comprehensive stroke center (CSC). During the start of the coronavirus 2019 pandemic (COVID-19), there were reports about disruption to emergency department (ED) operations and delays in management of patients with AIS-LVO. In this study we investigate the outcome and operations for patients who were transferred from different EDs to an academic CSC's critical care resuscitation unit (CCRU), which specializes in expeditious transfer of time-sensitive disease.

Methods: This was a pre-post retrospective study using prospectively collected clinical data from our CSC's stroke registry. Adult patients who were transferred from any ED to the CCRU and underwent MT were eligible. We compared time intervals in the pre-pandemic (PP) period between January 2018- February 2020, such as ED in-out and CCRU arrival-angiography, to those during the pandemic (DP) between March 2020-May 31, 2021. We used classification and regression tree (CART) analysis to identify which time intervals, besides clinical factors, were associated with good neurological outcome (90-day modified Rankin scale 0-2).

Results: We analyzed 203 patients: 135 (66.5%) in the PP group and 68 (33.5%) in the DP group. Time from ED triage to computed tomography (difference 7 minutes, 95% confidence interval [CI] -12 to -1, P < 0.01) for the DP group was statistically longer, but ED in-out was similar for both groups. Time from CCRU arrival to angiography (difference 9 minutes, 95% CI 4-13, P < 0.01) for the DP group was shorter. Forty-nine percent of the DP group achieved mRS ≤ 2 vs 32% for the PP group (difference -17%, 95% CI -0.32 to -0.03, P < 0.01). The CART identified initial National Institutes of Health Stroke Scale, age, ED in-and-out time, and CCRU arrival-to-angiography time as important predictors of good outcome.

Conclusion: Overall, the care process in EDs and at this single CSC for patients requiring MT were not heavily affected by the pandemic, as certain time metrics during the pandemic were statistically shorter than pre-pandemic intervals. Time intervals such as ED in-and-out and CCRU arrival-to-angiography were important factors in achieving good neurologic outcomes. Further study is necessary to confirm our observation and improve operational efficiency in the future.

Introduction: Optimizing the performance of emergency department (ED) teams impacts patient care, but the utility of current, team-based performance assessment tools to comprehensively measure this impact is underexplored. In this study we aimed to 1) evaluate ED team performance using current team-based assessment tools during an interprofessional in situ simulation and 2) identify characteristics of effective ED teams.

Methods: This mixed-methods study employed case study methodology based on a constructivist paradigm. Sixty-three eligible nurses, technicians, pharmacists, and postgraduate year 2-4 emergency medicine residents at a tertiary academic ED participated in a 10-minute in situ simulation of a critically ill patient. Participants self-rated performance using the Team Performance Observation Tool (TPOT) 2.0 and completed a brief demographic form. Two raters independently reviewed simulation videos and rated performance using the TPOT 2.0, Team Emergency Assessment Measure (TEAM), and Ottawa Crisis Resource Management Global Rating Scale (Ottawa GRS). Following simulations, we conducted semi-structured interviews and focus groups with in situ participants. Transcripts were analyzed using thematic analysis.

Results: Eighteen team-based simulations took place between January-April 2021. Raters' scores were on the upper end of the tools for the TPOT 2.0 (R1 4.90, SD 0.17; R2 4.53, SD 0.27, IRR [inter-rater reliability] 0.47), TEAM (R1 3.89, SD 0.19; R2 3.58, SD 0.39, IRR 0.73), and Ottawa GRS (R1 6.6, SD 0.56; R2 6.2, SD 0.54, IRR 0.68). We identified six themes from our interview data: team member entrustment; interdependent energy; leadership tone; optimal communication; strategic staffing; and simulation empowering team performance.

Conclusion: Current team performance assessment tools insufficiently discriminate among high performing teams in the ED. Emergency department-specific assessments that capture features of entrustability, interdependent energy, and leadership tone may offer a more comprehensive way to assess an individual's contribution to a team's performance.

Introduction: As opioid overdose deaths continue to rise, the emergency department (ED) remains an important point of contact for many at risk for overdose. In this study our purpose was to better understand the attitudes, beliefs, and knowledge of ED nurses in caring for patients with opioid use disorder (OUD). We hypothesized a difference in training received and attitudes toward caring for patients with OUD between nurses with <5 years and ≥6 years of clinical experience.

Methods: We conducted a survey among ED nurses in a large academic medical center from May-July 2022. All ED staff nurses were surveyed. Data entry instruments for the nursing surveys were programmed in Qualtrics, and we analyzed results R using a chi-square test or Fisher exact test to compare nurses with <5 years and ≥6 years of clinical experience. A P-value of < 0.05 was considered statistically significant.

Results: We distributed 74 surveys, and 69 were completed (93%). Attitudes toward naloxone distribution from the ED were positive, with 72% of respondents reporting they were "very" or "extremely" supportive of distributing naloxone kits to individuals at risk of overdose. While attitudes were positive, barriers included limited time, lack of system support, and cost. Level of comfort in caring for patients with OUD was high, with 78% of respondents "very" or "extremely" comfortable. More education is needed on overdose education and naloxone distribution (OEND) with respondents 38% and 45% "a little" or "somewhat" comfortable, respectively. Nurses with <5 years of experience reported receiving more training on OEND in nursing school compared to those with ≥6 years of experience (P = 0.03). There were no significant differences in reported attitudes, knowledge, or comfort in caring for patients with OUD.

Conclusion: In this single-center survey, we found ED nurses were supportive of overdose education and naloxone distribution. There are opportunities for targeted education and addressing systemic barriers to OEND. All interventions should be evaluated to gauge impact on knowledge, attitudes, and behaviors.

Introduction: To expand access to naloxone, the state of Illinois implemented a standing order allowing registered pharmacies to dispense the drug without an individual prescription. To participate under the standing order, pharmacies were required to opt in through a formal registration process. In our study we aimed to evaluate the availability and price of naloxone at registered pharmacies.

Methods: This was a prospective, de-identified, cross-sectional telephone survey. Trained interviewers posed as potential customers and used a standardized script to determine the availability of naloxone between February-December, 2019. The primary outcome was defined as a pharmacy indicating it carried naloxone, currently had naloxone in stock, and was able to dispense it without an individual prescription.

Results: Of 948 registered pharmacies, 886 (93.5%) were successfully contacted. Of those, 792 (83.4%) carried naloxone, 659 (74.4%) had naloxone in stock, and 472 (53.3%) allowed purchase without a prescription. Naloxone nasal spray (86.4%) was the formulation most commonly stocked. Chain pharmacies were more likely to carry naloxone (adjusted odds ratio [aOR] 3.16, 95% confidence interval [CI] 1.97-5.01, P < 0.01) and have naloxone in stock (aOR 2.72, 95% CI 1.76-4.20, P < 0.01), but no more likely to dispense it without a prescription. Pharmacies in higher population areas (aOR 0.99, 95% CI 0.99-0.99, P < 0.05) and rural areas adjacent to metropolitan areas (aOR 0.5, 95% CI 025-0.98, P < 0.05) were less likely to have naloxone available without a prescription. Associations of naloxone availability based on other urbanicity designations, overdose count, and overdose rate were not significant.

Conclusion: Among pharmacies in Illinois that formally registered to dispense naloxone without a prescription, the availability of naloxone remains limited. Additional interventions may be needed to maximize the potential impact of a statewide standing order.
