RESUMO
INTRODUCTION: The World Health Organization developed Emergency Triage Assessment and Treatment Plus (ETAT+) guidelines to facilitate pediatric care in resource-limited settings. ETAT+ triages patients as nonurgent, priority, or emergency cases, but there is limited research on the performance of ETAT+ regarding patient-oriented outcomes. This study assessed the diagnostic accuracy of ETAT+ in predicting the need for hospital admission in a pediatric emergency unit at Kenyatta National Hospital in Nairobi, Kenya. METHODS: This was a secondary analysis of a cross-sectional study of pediatric emergency unit patients enrolled over a 4-week period using fixed random sampling. Diagnostic accuracy of ETAT+ was evaluated using receiver operating curves (ROCs) and respective 95% confidence intervals (CIs) with associated sensitivity and specificity (reference category: nonurgent). The ROC analysis was performed for the overall population and stratified by age group. RESULTS: A total of 323 patients were studied. The most common reasons for presentation were upper respiratory tract disease (32.8%), gastrointestinal disease (15.5%), and lower respiratory tract disease (12.4%). Two hundred twelve participants were triaged as nonurgent (65.6%), 60 as priority (18.6%), and 51 as emergency (15.8%). In the overall study population, the area under the ROC curve was 0.97 (95% CI, 0.95-0.99). The ETAT+ sensitivity was 93.8% (95% CI, 87.0%-99.0%), and the specificity was 82.0% (95% CI, 77.0%-87.0%) for admission of priority group patients. The sensitivity and specificity for the emergency patients were 66.0% (95% CI, 55.0%-77.0%) and 98.0% (95% CI, 97.0%-100.0%), respectively. CONCLUSIONS: ETAT+ demonstrated diagnostic accuracy for predicting patient need for hospital admission. This finding supports the utility of ETAT+ to inform emergency care practice. Further research on ETAT+ performance in larger populations and additional patient-oriented outcomes would enhance its generalizability and application in resource-limited settings.
RESUMO
We conducted a retrospective cohort study to assess the effect vaccination with the live-attenuated recombinant vesicular stomatitis virus-Zaire Ebola virus vaccine had on deaths among patients who had laboratory-confirmed Ebola virus disease (EVD). We included EVD-positive patients coming to an Ebola Treatment Center in eastern Democratic Republic of the Congo during 2018-2020. Overall, 25% of patients vaccinated before symptom onset died compared with 63% of unvaccinated patients. Vaccinated patients reported fewer EVD-associated symptoms, had reduced time to clearance of viral load, and had reduced length of stay at the Ebola Treatment Center. After controlling for confounders, vaccination was strongly associated with decreased deaths. Reduction in deaths was not affected by timing of vaccination before or after EVD exposure. These findings support use of preexposure and postexposure recombinant vesicular stomatitis virus-Zaire Ebola virus vaccine as an intervention associated with improved death rates, illness, and recovery time among patients with EVD.

BACKGROUND: Empiric antimalarial treatment is a component of protocol-based management of Ebola virus disease (EVD), yet this approach has limited clinical evidence for patient-centered benefits. METHODS: This retrospective cohort study evaluated the association between antimalarial treatment and mortality among patients with confirmed EVD. The data was collected from five International Medical Corps operated Ebola Treatment Units (ETUs) in Sierra Leone and Liberia from 2014 through 2015. The standardized protocol used for patient care included empiric oral treatment with combination artemether and lumefantrine, twice daily for three days; however, only a subset of patients received treatment due to resource variability. The outcome of interest was mortality, comparing patients treated with oral antimalarials within 48-h of admission to those not treated. Analysis was conducted with logistic regression to generate adjusted odds ratios (aORs). Multivariable analyses controlled for ETU country, malaria rapid diagnostic test result, age, EVD cycle threshold value, symptoms of bleeding, diarrhea, dysphagia and dyspnea, and additional standard clinical treatments. RESULTS: Among the 424 cases analyzed, 376 (88.7%) received early oral antimalarials. Across all cases, mortality occurred in 57.5% (244). In comparing unadjusted mortality prevalence, early antimalarial treated cases yielded 55.1% mortality versus 77.1% mortality for those untreated (p = 0.005). Multivariable analysis demonstrated evidence of reduced aOR for mortality with early oral antimalarial treatment versus non-treatment (aOR = 0.34, 95% Confidence Interval: 0.12, 0.92, p = 0.039). CONCLUSION: Early oral antimalarial treatment in an EVD outbreak was associated with reduced mortality. Further study is warranted to investigate this association between early oral antimalarial treatment and mortality in EVD patients.

INTRODUCTION: The epidemiology and presence of pediatric medical emergencies and injury prevention practices in Kenya and resource-limited settings are not well understood. This is a barrier to planning and providing quality emergency care within the local health systems. We performed a prospective, cross-sectional study to describe the epidemiology of case encounters to the pediatric emergency unit (PEU) at Kenyatta National Hospital in Nairobi, Kenya; and to explore injury prevention measures used in the population. METHODS: Patients were enrolled prospectively using systematic sampling over four weeks in the Kenyatta National Hospital PEU. Demographic data, PEU visit data and lifestyle practices associated with pediatric injury prevention were collected directly from patients or guardians and through chart review. Data were analyzed with descriptive statistics with stratification based on pediatric age groups. RESULTS: Of the 332 patients included, the majority were female (56%) and 76% were under 5 years of age. The most common presenting complaints were cough (40%) fever (34%), and nausea/vomiting (19%). The most common PEU diagnoses were upper respiratory tract infections (27%), gastroenteritis (11%), and pneumonia (8%). The majority of patients (77%) were discharged from the PEU, while 22% were admitted. Regarding injury prevention practices, the majority (68%) of guardians reported their child never used seatbelts or car seats. Of 68 patients that rode bicycles/motorbikes, one reported helmet use. More than half of caregivers cook at potentially dangerous heights; 59% use ground/low level stoves. CONCLUSIONS: Chief complaints and diagnoses in the PEU population were congruent with communicable disease burdens seen globally. Measures for primary injury prevention were reported as rarely used in the sample studied. The epidemiology described by this study provides a framework for improving public health education and provider training in resource-limited settings.

BACKGROUND: Exclusive breastfeeding (EBF) is the optimal way to feed young infants. Guidelines recommend that women living with HIV on antiretroviral therapy should EBF for 6 months and continue breastfeeding for up to 24 months or longer. Parents may face social or logistical barriers creating challenges to EBF. OBJECTIVES: To explore barriers, facilitators and community norms influencing EBF practices in Kenya. METHODS: This qualitative research was nested within a longitudinal study of intensive maternal counseling to increase EBF among HIV-positive mothers. HIV-negative and HIV-positive mothers were recruited from four public clinics in Nairobi. Women participated in focus group discussions (FGDs) that explored beliefs about and experiences with infant feeding. Conventional content analysis was used to describe and compare barriers and facilitators influencing HIV-positive and HIV-negative women's EBF experiences. RESULTS: We conducted 17 FGDs with 80 HIV-positive and 53 HIV-negative women between 2009 and 2012. Overall, women agreed that breastmilk is good for infants. However, early mixed feeding was a common cultural practice. HIV-positive women perceived that infant feeding methods and durations were their decision. In contrast, HIV-negative women reported less autonomy and more mixed feeding, citing peer pressure and lack of HIV transmission concerns. Autonomy in decision-making was facilitated by receiving EBF counseling and family support, especially from male partners. Low milk production was a barrier to EBF, regardless of HIV status, and perceived to represent poor maternal nutrition. CONCLUSIONS: Despite challenges, counseling empowered women living with HIV to advocate for EBF with spouses and family.

BACKGROUND: Intravenous fluid (IVF) is a frequently recommended intervention in Ebola virus disease (EVD), yet its impact on patient outcomes remains unclear. METHODS: This retrospective cohort study evaluated patients with EVD admitted to 5 Ebola treatment units (ETUs) in West Africa. The primary outcome was the difference in 28-day survival between cases treated and not treated with IVF. To control for demographic and clinical factors related to both IVF exposure and survival, cases were compared using propensity score matching. To control for time-varying patient and treatment factors over the course of ETU care, a marginal structural proportional hazards model (MSPHM) with inverse probability weighting was used to assess for 28-day survival differences. RESULTS: Among 424 EVD-positive cases with data for analysis, 354 (83.5%) were treated with IVF at some point during their ETU admission. Overall, 146 (41.3%) cases treated with IVF survived, whereas 31 (44.9%) cases not treated with any IVF survived (P = .583). Matched propensity score analysis found no significant difference in 28-day survival between cases treated and not treated with IVF during their first 24 and 48 hours of care. Adjusted MSPHM survival analyses also found no significant difference in 28-day survival for cases treated with IVF (27.3%) compared to those not treated with IVF (26.9%) during their entire ETU admission (P = .893). CONCLUSIONS: After adjustment for patient- and treatment-specific time-varying factors, there was no significant difference in survival among patients with EVD treated with IVF as compared to those not treated with IVF.

OBJECTIVE: To evaluate the association between oral third-generation cephalosporin antibiotic treatment and mortality in Ebola virus disease (EVD). METHODS: This retrospective cohort studied EVD-infected patients admitted to five Ebola Treatment Units in Sierra Leone and Liberia during 2014-15. Empiric treatment with cefixime 400 mg once daily for five days was the clinical protocol; however, due to resource variability, only a subset of patients received treatment. Data on sociodemographics, clinical characteristics, malaria status and Ebola viral loads were collected. The primary outcome was mortality compared between cases treated with cefixime within 48 h of admission to those not treated within 48 h. Propensity scores were derived using clinical covariates. Mortality between treated and untreated cases was compared using propensity-matched conditional logistic regression and bootstrapped log-linear regression analyses to calculate an odds ratio (OR) and relative risk (RR), respectively, with associated 95% confidence intervals (CI). RESULTS: Of 424 cases analysed, 360 (84.9%) met the cefixime treatment definition. The mean age was 30.5 years and 40.3% were male. Median cefixime treatment duration was 4 days (IQR: 3, 5). Among cefixime-treated patients, mortality was 54.7% (95% CI: 49.6-59.8%) vs. 73.4% (95% CI: 61.5-82.7%) in untreated patients. In conditional logistic regression, mortality likelihood was significantly lower among cases receiving cefixime (OR = 0.48, 95% CI: 0.32-0.71; P = 0.01). In the bootstrap analysis, a non-significant risk reduction was found with cefixime treatment (RR = 0.82, 95% CI: 0.64-1.16, P = 0.11). CONCLUSION: Early oral cefixime may be associated with reduced mortality in EVD and warrants further investigation.
OBJECTIF: Evaluer l'association entre le traitement antibiotique oral avec des céphalosporine de troisième génération et la mortalité dans la maladie au virus Ebola (MVE). MÉTHODES: Cette étude de cohorte rétrospective a été menée chez des patients infectés par la maladie au virus Ebola admis dans cinq unités de traitement Ebola en Sierra Leone et au Libéria en 2014-2015. Le traitement empirique avec Cefixime 400 mg une fois par jour pendant cinq jours était le protocole clinique. Cependant, en raison de la variabilité des ressources, seul un sous-ensemble de patients a reçu un traitement. Des données sur la sociodémographie, les caractéristiques cliniques, le statut du paludisme et les charges virales d'Ebola ont été collectées. Le critère principal était la mortalité comparée entre les cas traités au céfixime dans les 48 heures suivant l'admission et ceux non traités dans les 48 heures. Les scores de propension ont été dérivés à l'aide de covariables cliniques. La mortalité entre les cas traités et non traités a été comparée à l'aide d'analyses de régression logistique conditionnelle et de régression log-linéaire bootstrapées pour calculer respectivement un rapport de cotes (OR) et un risque relatif (RR), avec des intervalles de confiance (IC) à 95% associés. RÉSULTATS: Sur 424 cas analysés, 360 (84,9%) répondaient à la définition du traitement au céfixime. L'âge moyen était de 30,5 ans et 40,3% étaient des hommes. La durée médiane du traitement par le céfixime était de 4 jours (IQR: 3, 5). Parmi les patients traités au Cefixime, la mortalité était de 54,7% (IC95%: 49,6 à 59,8%) vs 73,4% (IC95%: 61,5 à 82,7%) chez les patients non traités. Dans la régression logistique conditionnelle, la probabilité de mortalité était significativement plus faible parmi les cas recevant du céfixime (OR = 0,48 ; IC95%: 0,32 à 0,71; P = 0,01). Dans l'analyse bootstrap, une réduction du risque non significative a été trouvée avec le traitement au céfixime (RR = 0,82, IC95%: 0,64 à 1,16 ; P = 0,11). CONCLUSION: Le céfixime par voie orale rapide peut être associé à une mortalité réduite dans la MVE et mérite une investigation plus approfondie.

STUDY OBJECTIVE: We determine whether interpolated questions in a podcast improve knowledge acquisition and retention. METHODS: This double-blinded controlled trial randomized trainees from 6 emergency medicine programs to listen to 1 of 2 versions of a podcast, produced de novo on the history of hypertension. The versions were identical except that 1 included 5 interpolated questions to highlight educational points (intervention). There were 2 postpodcast assessments, 1 within 48 hours of listening (immediate posttest) and a second 2 to 3 weeks later (retention test), consisting of the same 15 multiple-choice questions, 5 directly related to the interpolated questions and 10 unrelated. The primary outcome was the difference in intergroup mean assessment scores at each point. A sample size was calculated a priori to identify a significant interarm difference. RESULTS: One hundred thirty-seven emergency medicine trainees were randomized to listen to a podcast, 69 without interpolated questions (control) and 68 with them (intervention). Although no significant difference was detected at the immediate posttest, trainees randomized to the interpolated arm had a significantly higher mean score on the retention test, with a 5.6% absolute difference (95% confidence interval 0.2% to 10.9%). For the material covered by the interpolated questions, the intervention arm had significantly higher mean scores on both the immediate posttest and retention tests, with absolute differences of 8.7% (95% confidence interval 1.6% to 15.8%) and 10.1% (95% confidence interval 2.8% to 17.4%), respectively. There was no significant intergroup difference for noninterpolated questions. CONCLUSION: Podcasts containing interpolated questions improved knowledge retention at 2 to 3 weeks, driven by the retention of material covered by the interpolated questions. Although the gains may be modest, educational podcasters may improve knowledge retention by using interpolating questions.

BACKGROUND: Micronutrient supplementation is recommended in Ebola virus disease (EVD); however, there are limited data on therapeutic impacts of specific micronutrients. OBJECTIVE: To evaluate the association between vitamin A supplementation and mortality in EVD. METHODS: This retrospective cohort included patients with EVD admitted to 5 International Medical Corps Ebola Treatment Units (ETUs) in 2 countries during 2014-2015. Protocolized treatments with micronutrients were used at all ETUs: however, because of resource constraints, only a subset of patients received vitamin A. Standardized data on demographics, clinical characteristics, malaria status, and Ebola viral loads (cycle threshold values) were collected. The outcome of interest was mortality between cases treated with 200,000 IU of vitamin A on care days 1 and/or 2, and those not. Propensity scores based on the first 48 h of care were derived using covariates of age, ETU duration, malaria status, cycle threshold values, and clinical symptoms. Patients were matched 1:1 using nearest neighbors with replacement. Mortality between cases treated and not treated with vitamin A was compared using generalized estimating equations to calculate RR with associated 95% CI. RESULTS: There were 424 cases analyzed, of which 330 (77.8%) were treated with vitamin A. The mean age was 30.5 y and 40.3% were men. The most common symptoms were diarrhea (85.6%), anorexia (80.7%), and abdominal pain (76.9%). Mortality proportions among cases treated and not treated with vitamin A were 55.0% and 71.9%, respectively. In the propensity-matched analysis, mortality was significantly lower among cases receiving vitamin A (RR = 0.77, 95% CI: 0.59, 0.99; P = 0.041). In a subgroup analysis of patients treated with multivitamins already containing vitamin A, additional vitamin A supplementation did not impact mortality. CONCLUSION: Early vitamin A supplementation was associated with reduced mortality in patients with EVD, and should be further studied and considered for use in future epidemics.

OBJECTIVE: Fluid loss during Ebola virus disease (EVD) infections from gastrointestinal dysfunction leads to volume depletion. It is possible that high environmental temperatures may exacerbate volume depletion or interfere with the provision of medical care by providers in full personal protective equipment. We investigated the effect of environmental temperature on case fatality. METHODS: The International Medical Corps (IMC) operated five Ebola Treatment Units (ETUs) in Liberia and Sierra Leone during the 2014-2016 epidemic. Demographic and outcomes variables for 465 patients with EVD were sourced from a de-identified, quality-checked clinical database collected by IMC. Daily environmental temperature data for Liberia and Sierra Leone were collected from a publicly available database (Weather Underground). Mean daily environmental temperatures were averaged across each patient's ETU stay and environmental temperature thresholds were determined. Multiple logistic regression was utilised, with forward variable selection and threshold for entry of P < 0.1. Statistical significance was defined as P < 0.05. The following variables were analysed as potential confounders: age, sex, ETU, length of ETU operation and date of treatment. RESULTS: Case fatality was 57.6% among patients diagnosed with EVD. Analysis of case fatality across environmental temperature quintiles indicated a threshold effect; the optimal threshold for average environmental temperature during a patient's ETU stay was determined empirically to be 27.4 °C (81.3 °F). Case fatality was significantly greater for patients with average environmental temperatures above the threshold (70.4%) vs. below (52.0%) (P < 0.001). In multiple regression, patients with average environmental temperature above the threshold during their ETU stay were significantly more likely to die than patients below the threshold (aOR = 2.5, 95% CI 1.6-3.8, P < 0.001). This trend was observed only among patients treated in white tent ETUs, and not in ETUs with aluminium roofs. DISCUSSION: These findings suggest that an average environmental temperature above 27.4 °C (81.3 °F) during patients' ETU stay is associated with greater risk of death among patients with EVD. Further studies should investigate this effect. These results have potential implications for reducing case fatality through improved ETU construction or other temperature control methods within ETUs during future outbreaks.

BACKGROUND: Pediatric trauma is a significant public health problem in resource-constrained settings; however, the epidemiology of injuries is poorly defined in Rwanda. This study describes the characteristics of pediatric trauma patients transported to the emergency department (ED) of the Centre Hospitalier Universitaire de Kigali by emergency medical services in Kigali, Rwanda. METHODS: This cohort study was conducted at the Centre Hospitalier Universitaire de Kigali from December 2012 to February 2015. Patients 15 years or younger brought by emergency medical services for injuries to the ED were included. Prehospital and hospital-based data on demographics, injury characteristics, treatments, and outcomes were gathered. RESULTS: Data from 119 prehospital patients were accrued, with corresponding hospital data for 64 cases. The median age was 9.5 years, with most patients being male (67.2%). Injured children were most frequently brought from a street setting (69.6%). Road traffic injuries accounted for 69.4% of all mechanisms, with more than two thirds due to pedestrians being struck. Extremity trauma was the most common region of injury (53.1%), followed by craniofacial (46.8%). The most frequent ED interventions were analgesia (66.1%) and intravenous fluids (43.6%). Half of the 16 obtained head computed tomography scans demonstrated acute pathology. Twenty-eight patients (51.9%) were admitted, with 57.1% requiring surgery and having a median in-hospital care duration of 9 days (range, 1-122 days). CONCLUSIONS: In this cohort of Rwandan pediatric trauma patients, injuries to the extremities and craniofacial regions were most common. Theses traumatic patterns were predominantly due to road traffic injury, suggesting that interventions addressing the prevention of this mechanism, and treatment of the associated injury patterns, may be beneficial in the Rwandan setting.

OBJECTIVE: To evaluate the utility of the quick Sepsis-related Organ Failure Assessment (qSOFA) score to predict risks for emergency department (ED) and hospital mortality among patients in a sub-Saharan Africa (SSA) setting. METHODS: This retrospective cohort study was carried out at a tertiary-care hospital, in Kigali, Rwanda and included patients ≥15years, presenting for ED care during 2013 with an infectious disease (ID). ED and overall hospital mortality were evaluated using multivariable regression, with qSOFA scores as the primary predictor (reference: qSOFA=0), to yield adjusted relative risks (aRR) with 95% confidence intervals (CI). Analyses were performed for the overall population and stratified by HIV status. RESULTS: Among 15,748 cases, 760 met inclusion (HIV infected 197). The most common diagnoses were malaria and intra-abdominal infections. Prevalence of ED and hospital mortality were 12.5% and 25.4% respectively. In the overall population, ED mortality aRR was 4.8 (95% CI 1.9-12.0) for qSOFA scores equal to 1 and 7.8 (95% CI 3.1-19.7) for qSOFA scores ≥2. The aRR for hospital mortality in the overall cohort was 2.6 (95% 1.6-4.1) for qSOFA scores equal to 1 and 3.8 (95% 2.4-6.0) for qSOFA scores ≥2. For HIV infected cases, although proportional mortality increased with greater qSOFA score, statistically significant risk differences were not identified. CONCLUSION: The qSOFA score provided risk stratification for both ED and hospital mortality outcomes in the setting studied, indicating utility in sepsis care in SSA, however, further prospective study in high-burden HIV populations is needed.

Importance: The quick Sequential (Sepsis-Related) Organ Failure Assessment (qSOFA) score has not been well-evaluated in low- and middle-income countries (LMICs). Objective: To assess the association of qSOFA with excess hospital death among patients with suspected infection in LMICs and to compare qSOFA with the systemic inflammatory response syndrome (SIRS) criteria. Design, Settings, and Participants: Retrospective secondary analysis of 8 cohort studies and 1 randomized clinical trial from 2003 to 2017. This study included 6569 hospitalized adults with suspected infection in emergency departments, inpatient wards, and intensive care units of 17 hospitals in 10 LMICs across sub-Saharan Africa, Asia, and the Americas. Exposures: Low (0), moderate (1), or high (≥2) qSOFA score (range, 0 [best] to 3 [worst]) or SIRS criteria (range, 0 [best] to 4 [worst]) within 24 hours of presentation to study hospital. Main Outcomes and Measures: Predictive validity (measured as incremental hospital mortality beyond that predicted by baseline risk factors, as a marker of sepsis or analogous severe infectious course) of the qSOFA score (primary) and SIRS criteria (secondary). Results: The cohorts were diverse in enrollment criteria, demographics (median ages, 29-54 years; males range, 36%-76%), HIV prevalence (range, 2%-43%), cause of infection, and hospital mortality (range, 1%-39%). Among 6218 patients with nonmissing outcome status in the combined cohort, 643 (10%) died. Compared with a low or moderate score, a high qSOFA score was associated with increased risk of death overall (19% vs 6%; difference, 13% [95% CI, 11%-14%]; odds ratio, 3.6 [95% CI, 3.0-4.2]) and across cohorts (P < .05 for 8 of 9 cohorts). Compared with a low qSOFA score, a moderate qSOFA score was also associated with increased risk of death overall (8% vs 3%; difference, 5% [95% CI, 4%-6%]; odds ratio, 2.8 [95% CI, 2.0-3.9]), but not in every cohort (P < .05 in 2 of 7 cohorts). High, vs low or moderate, SIRS criteria were associated with a smaller increase in risk of death overall (13% vs 8%; difference, 5% [95% CI, 3%-6%]; odds ratio, 1.7 [95% CI, 1.4-2.0]) and across cohorts (P < .05 for 4 of 9 cohorts). qSOFA discrimination (area under the receiver operating characteristic curve [AUROC], 0.70 [95% CI, 0.68-0.72]) was superior to that of both the baseline model (AUROC, 0.56 [95% CI, 0.53-0.58; P < .001) and SIRS (AUROC, 0.59 [95% CI, 0.57-0.62]; P < .001). Conclusions and Relevance: When assessed among hospitalized adults with suspected infection in 9 LMIC cohorts, the qSOFA score identified infected patients at risk of death beyond that explained by baseline factors. However, the predictive validity varied among cohorts and settings, and further research is needed to better understand potential generalizability.

OBJECTIVE: This study describes emergency department (ED) sepsis patients with non-critical serum venous lactate (LAC) levels (LAC <4.0 mmol/L) who suffered in-hospital mortality and examines LAC in relation to survival times. METHODS: An ED based retrospective cohort study accrued September 2010 to August 2014. Inclusion criteria were ED admission, LAC sampling, >2 systemic inflammatory response syndrome criteria with an infectious source (sepsis), and in-hospital mortality. Kaplan-Meier curves were used for survival estimates. An a priori sub-group analysis for patients with repeat LAC within 6 hours of initial sampling was undertaken. The primary outcome was time to in-hospital death evaluated using rank-sum tests and regression models. RESULTS: One hundred ninety-seven patients met inclusion criteria. Pulmonary infections were the most common (44%) and median LAC was 1.9 mmol/L (1.5, 2.5). Thirteen patients (7%) died within 24 hours and 79% by ≤28 days. Median survival was 11 days (95% CI, 8.0-13). Sixty-two patients had repeat LAC sampling with 14 (23%) and 48 (77%) having decreasing increasing levels, respectively. No significant differences were observed in treatment requirements between the LAC subgroups. Among patients with decreasing LAC, median survival was 24 days (95% CI, 5-32). For patients with increasing LAC median survival was significantly shorter (7 days; 95% CI, 4-11, P = .04). Patients with increasing LAC had a non-significant trend toward reduced survival (HR = 1.6 95% CI, 0.90-3.0, P = .10). CONCLUSIONS: In septic ED patients experiencing in-hospital death, non-critical serum venous lactate may be utilized as a risk-stratifying tool for early mortality, while increasing LAC levels may identify those in danger of more rapid deterioration.

INTRODUCTION: Although prehospital care is recognized as key in health systems development, it has been largely neglected in Haiti. The North East Department is one of the poorest areas of Haiti, and is a region where no data on out-of-hospital health care exists. This research assessed prehospital characteristics in the North East Department with the aim of providing baseline data to inform prehospital systems development. METHODS: In this observational study, data were collected from patients presenting at the Fort Liberté Hospital, the public regional referral health center in the North East Department. Data were accrued from April 2, 2012 through June 5, 2012. All patients accessing acute care at the hospital were eligible for enrollment. After obtaining consent, data on demographics, health needs, and prehospital information were gathered via a standardized questionnaire administered by hospital staff trained in study protocols. RESULTS: Data were collected from 441 patient visits. The median age was 24 years, with 62% of the population being female. Medical complaints comprised 75% of visits, with fever and gastrointestinal complaints being the most common reasons for presentation. Traumatic injuries accounted for 25% of encounters, with an equal distribution of blunt and penetrating events. Extremity injuries were the most common traumatic subclassification. The majority of patients (67.2%) were transported by motorcycle taxi and paid transport fees. Trauma patients were more likely to be transported without charge (OR = 9.10; 95% CI, 2.19-37.76; P < .001). Medical patients were most commonly brought from home (78.5%) and trauma patients from a road/street setting (42.9%). Median time to presentation was 240 minutes (IQR = 120-500) and 65 minutes (IQR = 30-150) for medical and trauma complaints, respectively (P < .001). Eleven percent of patients reported receiving care prior to arrival. As compared with medical patients, trauma victims were less likely to have received prehospital care. CONCLUSIONS: Assessing prehospital care in this low-income setting that lacks surveillance systems was feasible and required minimal resources. Motorcycle taxi drivers function as the primary emergency transport mechanism and may represent an access point for prehospital interventions in the North East Department of Haiti. Out-of-hospital care is nearly nonexistent in the region and its development has the potential to yield public health benefits.

BACKGROUND: Interpersonal violence is a significant contributor to global morbidity, and affects young adults, particularly males. In Kenya, injuries, including those from interpersonal violence, are a leading cause of emergency department (ED) visits. OBJECTIVE: This study aims to evaluate the frequency, demographics, and types of injuries caused by interpersonal and intimate partner violence among patients presenting to the Kenyatta National Hospital (KNH) ED in Nairobi, Kenya. METHODS: This was a prospective cross-sectional study among injured adult patients presenting to the KNH ED. RESULTS: Of 665 enrolled patients, 82% identified as male and the median age was 30 years. Among enrollees, 257 (39%) reported ever having experienced physical, sexual, and/or emotional violence. Seventy-one patients reported a history of intimate partner violence; more than half had experienced intimate partner violence within the past 12 months. CONCLUSIONS: Research on interpersonal injuries in ED settings is lacking, but data from a single Kenyan ED reveals a significant portion of injured patients with a history of interpersonal and intimate partner violence.

Background: Persons seeking emergency injury care are often from underserved key populations (KPs) and priority populations (PPs) for HIV programming. While facility-based HIV Testing Services (HTS) in Kenya are effective, emergency department (ED) delivery is limited, despite the potential to reach underserved persons. Methods: This quasi-experimental prospective study evaluated implementation of the HIV Enhanced Access Testing in Emergency Departments (HEATED) at Kenyatta National Hospital ED in Nairobi, Kenya. The HEATED program was designed using setting specific data and utilizes resource reorganization, services integration and HIV sensitization to promote ED-HTS. KPs included sex workers, gay men, men who have sex with men, transgender persons and persons who inject drugs. PPs included young persons (18-24 years), victims of interpersonal violence, persons with hazardous alcohol use and those never previously HIV tested. Data were obtained from systems-level records, enrolled injured patient participants and healthcare providers. Systems and patient-level data were collected during a pre-implementation period (6 March - 16 April 2023) and post-implementation (period 1, 1 May - 26 June 2023). Additional, systems-level data were collected during a second post-implementation (period 2, 27 June - 20 August 2023). Evaluation analyses were completed across reach, effectiveness, adoption, implementation and maintenance framework domains. Results: All 151 clinical staff were reached through trainings and sensitizations on the HEATED program. Systems-level ED-HTS increased from 16.7% pre-implementation to 23.0% post-implementation periods 1 and 2 (RR=1.31, 95% CI:1.21-1.43; p<0.001) with a 62.9% relative increase in HIV self-test kit provision. Among 605 patient participants, facilities-based HTS increased from 5.7% pre-implementation to 62.3% post-implementation period 1 (RR=11.2, 95%CI:6.9-18.1; p<0.001). There were 440 (72.7%) patient participants identified as KPs (5.6%) and/or PPs (65.3%). For enrolled KPs/PPs, HTS increased from 4.6% pre-implementation to 72.3% post-implementation period 1 (RR=13.8, 95%CI:5.5-28.7, p<0.001). Systems and participant level data demonstrated successful adoption and implementation of the HEATED program. Through 16-weeks post-implementation a significant increase in ED-HTS delivery was maintained as compared to pre-implementation. Conclusions: The HEATED program increased ED-HTS and augmented delivery to KPs/PPs, suggesting that broader implementation could improve HIV services for underserved persons, already in contact with health systems.
RESUMO
Background: Although multiple prognostic models exist for Ebola virus disease mortality, few incorporate biomarkers, and none has used longitudinal point-of-care serum testing throughout Ebola treatment center care. Methods: This retrospective study evaluated adult patients with Ebola virus disease during the 10th outbreak in the Democratic Republic of Congo. Ebola virus cycle threshold (Ct; based on reverse transcriptase polymerase chain reaction) and point-of-care serum biomarker values were collected throughout Ebola treatment center care. Four iterative machine learning models were created for prognosis of mortality. The base model used age and admission Ct as predictors. Ct and biomarkers from treatment days 1 and 2, days 3 and 4, and days 5 and 6 associated with mortality were iteratively added to the model to yield mortality risk estimates. Receiver operating characteristic curves for each iteration provided period-specific areas under curve with 95% CIs. Results: Of 310 cases positive for Ebola virus disease, mortality occurred in 46.5%. Biomarkers predictive of mortality were elevated creatinine kinase, aspartate aminotransferase, blood urea nitrogen (BUN), alanine aminotransferase, and potassium; low albumin during days 1 and 2; elevated C-reactive protein, BUN, and potassium during days 3 and 4; and elevated C-reactive protein and BUN during days 5 and 6. The area under curve substantially improved with each iteration: base model, 0.74 (95% CI, .69-.80); days 1 and 2, 0.84 (95% CI, .73-.94); days 3 and 4, 0.94 (95% CI, .88-1.0); and days 5 and 6, 0.96 (95% CI, .90-1.0). Conclusions: This is the first study to utilize iterative point-of-care biomarkers to derive dynamic prognostic mortality models. This novel approach demonstrates that utilizing biomarkers drastically improved prognostication up to 6 days into patient care.
RESUMO
Introduction: While trends in analgesia have been identified in high-income countries, little research exists regarding analgesia administration in low- and middle-income countries (LMIC). This study evaluates analgesia administration and clinical characteristics among patients seeking emergency injury care at University Teaching Hospital-Kigali in Kigali, Rwanda. Methods: This retrospective, cross-sectional study utilized a random sample of emergency center (EC) cases accrued between July 2015 and June 2016. Data was extracted from the medical record for patients who had an injury and were ≥ 15 years of age. Injury-related EC visits were identified by presenting complaint or final discharge diagnosis. Sociodemographic information, injury mechanism and type, and analgesic medications ordered and administered were analyzed. Results: Of the 3,609 random cases, 1,329 met eligibility and were analyzed. The study population was predominantly male (72%) with a median age of 32 years and range between 15 and 81 years. In the studied sample, 728 (54.8%) were treated with analgesia in the EC. In unadjusted logistic regression, only age was not a significant predictor of receiving pain medication and was excluded from the adjusted analysis. In the adjusted model, all predictors remained significant, with being male, having at least one severe injury, and road traffic accident (RTA) as injury mechanism being significant predictors of analgesia administration. Conclusion: In the study setting of injured patients in Rwanda, being male, involved in RTA or having more than one serious injury was associated with higher odds of receiving pain medication. Approximately half of the patients with traumatic injuries received pain medications, predominantly opioids with no factors predicting whether a patient would receive opioids versus other medications. Further research on implementation of pain guidelines and drug shortages is warranted to improve pain management for injured patients in the LMIC setting.
RESUMO
BACKGROUND: Emergency department-based HIV self-testing (ED-HIVST) could increase HIV-testing services to high-risk, under-reached populations. OBJECTIVES: This study sought to understand the injury patient acceptability of ED-HIVST. METHODS: Injury patients presenting to the Kenyatta National Hospital Accident and Emergency Department were enrolled from March to May 2021. Likert item data on HIVST assessing domains of general acceptability, personal acceptability, and acceptability to distribute to social and/or sexual networks were collected. Ordinal regression was performed yielding adjusted odds ratios (aOR) to identify characteristics associated with high HIVST acceptability across domains. RESULTS: Of 600 participants, 88.7% were male, and the median age was 29. Half reported having primary care providers (PCPs) and 86.2% reported prior HIV testing. For each Likert item, an average of 63.5% of the participants reported they 'Agree Completely' with positive statements about ED-HIVST in general, for themselves, and for others. In adjusted analysis for general acceptability, those <25 (aOR = 1.67, 95%CI:1.36-2.08) and with prior HIV testing (aOR = 1.68, 95%CI:1.27-2.21) had greater odds of agreeing completely. For personal acceptability, those with a PCP (aOR = 3.31, 95%CI:2.72-4.03) and prior HIV testing (aOR = 1.83, 95%CI:1.41-2.38) had greater odds of agreeing completely. For distribution acceptability, participants with a PCP (aOR = 2.42, 95%CI:2.01-2.92) and prior HIV testing (aOR = 1.79, 95%CI: 1.38-2.33) had greater odds of agreeing completely. CONCLUSIONS: ED-HIVST is perceived as highly acceptable, and young people with prior testing and PCPs had significantly greater favourability. These data provide a foundation for ED-HIVST programme development in Kenya.
