Building a framework to decolonize global emergency medicine.

Background: Global emergency medicine (GEM) is situated at the intersection of global health and emergency medicine (EM), which is built upon a history of colonial systems and institutions that continue to reinforce inequities between high-income countries (HICs) and low- and middle-income countries (LMICs) today. These power imbalances yield disparities in GEM practice, research, and education. Approach: The Global Emergency Medicine Academy (GEMA) of the Society for Academic Emergency Medicine formed the Decolonizing GEM Working Group in 2020, which now includes over 100 worldwide members. The mission is to address colonial legacies in GEM and catalyze sustainable changes and recommendations toward decolonization at individual and institutional levels. To develop recommendations to decolonize GEM, the group conducted a nonsystematic review of existing literature on decolonizing global health, followed by in-depth discussions between academics from LMICs and HICs to explore implications and challenges specific to GEM. We then synthesized actionable solutions to provide recommendations on decolonizing GEM. Results: Despite the rapidly expanding body of literature on decolonizing global health, there is little guidance specific to the relatively new field of GEM. By applying decolonizing principles to GEM, we suggest key priorities for improving equity in academic GEM: (1) reframing partnerships to place LMIC academics in positions of expertise and power, (2) redirecting research funding toward LMIC-driven projects and investigators, (3) creating more equitable practices in establishing authorship, and (4) upholding principles of decolonization in the education of EM trainees from LMICs and HICs. Conclusions: Understanding the colonial roots of GEM will allow us to look more critically at current health disparities and identify inequitable institutionalized practices within our profession that continue to uphold these misguided concepts. A decolonized future of GEM depends on our recognition and rectification of colonial-era practices that shape structural determinants of health care delivery and scientific advancement.

Content validation of needs assessment survey for remote education initiative in Tanzania.

Background: Historically, educational initiatives in global health have involved expert lectures by visitors. However, incomplete understanding of the target population and resources can limit the efficacy of lectures by international faculty. Little data exists on the magnitude of this problem. The goal of this study was to create and validate a needs assessment tool to guide lecture development as part of a larger study to implement virtual lectures for a residency program in Tanzania by members of an American faculty. Methods: Two study authors familiar with the Tanzanian hospital and residency program derived surveys for local residents and faculty. An expert panel consisting of two faculty members and one resident from each institution evaluated the questions. Each item was rated from 1 to 4 for clarity and relevance respectively. A content validity index (CVI) was calculated for each item using the proportion of experts who rated it as valid. Items with a CVI < 0.8 were revised and resubmitted. A CVI was then calculated for each instrument. Results: On the initial resident survey, 20 of 26 items were clear and 25 of 26 items were relevant with a CVI > 0.8. One item was deemed irrelevant and deleted. For the faculty survey, 10 of 12 items were clear and all items were relevant with CVI > 0.8. Five questions from the resident survey and two from the faculty survey deemed relevant but unclear were rewritten and resubmitted to experts. They all achieved CVI>0.8. Each survey obtained a CVI of 1. Conclusions: Using this approach, we validated a needs assessment tool to guide the creation of didactics for audiences that practice in a different setting from the lecturer.  This validated tool is an important step in the creation of a process to develop appropriate content and could be replicated by other groups planning similar initiatives.

Drug and alcohol use in Tanzanian road traffic collision drivers.

INTRODUCTION: Road traffic collisions (RTCs) are an important public health problem in low and middle-income countries (LMIC), where 90% of RTC deaths occur. The World Health Organization has suggested strategies to address excess mortality from RTCs including efforts to combat driving after using alcohol or drugs. Data on the impact of drug and alcohol use on RTCs is limited in many low-resource settings including Tanzania. We sought to examine the prevalence of drug and alcohol use in Tanzanian RTC drivers. METHODS: This prospective, observational study was conducted in the emergency centre (EC) of Muhimbili National Hospital (MNH) in Dar es Salaam, Tanzania. We enrolled adult drivers presenting within 24 h of an RTC. We collected a saliva test of blood alcohol content (BAC) and a urine drug screen (UDS) and administered a validated substance use disorder screening tool, the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Patients were excluded from individual analyses if they could not produce saliva or urine or answer questions. Primary outcomes were rates of positive BAC, UDS and self-reported risky alcohol and drug use patterns. RESULTS: We screened 5264 trauma patients and enrolled 418, in whom 190 had a BAC, 364 had a UDS, and 410 had a complete ASSIST. 15 of 190 patients (7.9%) had a positive BAC, and 67/361 (18.7%) had a positive UDS for at least one drug. ASSIST scores showed 75/410 (18.3%) patients were at moderate or high risk for alcohol use disorder. Few were at risk for disordered use of other non-tobacco substances. DISCUSSION: In our population of RTC drivers, positive BAC and UDS tests were rare but many patients were at risk for an alcohol use disorder. Ideal screening for substance use in Tanzanian trauma populations may involve a combination of objective testing and a verbal screening tool.

PLUMBER Study (Prevalence of Large Vessel Occlusion Strokes in Mecklenburg County Emergency Response).

BACKGROUND AND PURPOSE: The recently proposed American Heart Association/American Stroke Association EMS triage algorithm endorses routing patients with suspected large vessel occlusion (LVO) acute ischemic strokes directly to endovascular centers based on a stroke severity score. The predictive value of this algorithm for identifying LVO is dependent on the overall prevalence of LVO acute ischemic stroke in the EMS population screened for stroke, which has not been reported. METHODS: We performed a cross-sectional study of patients transported by our county's EMS agency who were dispatched as a possible stroke or had a primary impression of stroke by paramedics. We determined the prevalence of LVO by reviewing medical record imaging reports based on a priori specified criteria. RESULTS: We enrolled 2402 patients, of whom 777 (32.3%) had an acute stroke-related diagnosis. Among 485 patients with acute ischemic stroke, 24.1% (n=117) had an LVO, which represented only 4.87% (95% confidence interval, 4.05%-5.81%) of the total EMS population screened for stroke. CONCLUSIONS: Overall, the prevalence of LVO acute ischemic stroke in our EMS population screened for stroke was low. This is an important consideration for any EMS stroke severity-based triage protocol and should be considered in predicting the rates of overtriage to endovascular stroke centers.

Prevalence and molecular characteristics of methicillin-resistant Staphylococcus aureus among skin and soft tissue infections in an emergency department in Guyana.

OBJECTIVE: The characteristics of staphylococcal skin and soft tissue infections (SSTIs) are poorly understood in northern South America and the Caribbean. The objectives of this study were to determine the frequency of methicillin resistance among Staphylococcus aureus isolates in an emergency department (ED) in Guyana and to identify specific molecular characteristics of these methicillin-resistant Staphylococcus aureus (MRSA) strains. METHODS: This was a cross-sectional study conducted at the main teaching hospital in Georgetown, Guyana. Eligible subjects included patients of all ages with SSTIs with obtainable purulent material. Purulent material was cultured, and S. aureus isolates were evaluated for antibiotic susceptibilities by disc diffusion. Molecular characterisation of MRSA isolates included identification of SCCmec type, assignment of genetic relatedness by rep-PCR and determination of the presence of two exotoxins, Panton-Valentine Leukocidin (PVL) and LukAB. RESULTS: Eighty-five samples were collected; of these, 47 grew S. aureus. 24 of the 47 S. aureus samples were MRSA (51%; 95% CI 37% to 65%), representing 28% of all samples. All MRSA isolates were SCCmec type IV, PVL positive, LukAB positive and were highly related to the current epidemic clone in the USA, USA300. CONCLUSIONS: Here, we demonstrate a clinically significant proportion of methicillin resistance in SSTI-associated staphylococcal isolates. Guyanese isolates were highly related to the most common community-associated strain seen in the USA, USA300. These results have important implications for empiric antibiotic therapy and infection control policies in Guyana and similar settings.
