Constructing, validating, and updating machine learning models to predict survival in children with Ebola Virus Disease.

BACKGROUND: Ebola Virus Disease (EVD) causes high case fatality rates (CFRs) in young children, yet there are limited data focusing on predicting mortality in pediatric patients. Here we present machine learning-derived prognostic models to predict clinical outcomes in children infected with Ebola virus. METHODS: Using retrospective data from the Ebola Data Platform, we investigated children with EVD from the West African EVD outbreak in 2014-2016. Elastic net regularization was used to create a prognostic model for EVD mortality. In addition to external validation with data from the 2018-2020 EVD epidemic in the Democratic Republic of the Congo (DRC), we updated the model using selected serum biomarkers. FINDINGS: Pediatric EVD mortality was significantly associated with younger age, lower PCR cycle threshold (Ct) values, unexplained bleeding, respiratory distress, bone/muscle pain, anorexia, dysphagia, and diarrhea. These variables were combined to develop the newly described EVD Prognosis in Children (EPiC) predictive model. The area under the receiver operating characteristic curve (AUC) for EPiC was 0.77 (95% CI: 0.74-0.81) in the West Africa derivation dataset and 0.76 (95% CI: 0.64-0.88) in the DRC validation dataset. Updating the model with peak aspartate aminotransferase (AST) or creatinine kinase (CK) measured within the first 48 hours after admission increased the AUC to 0.90 (0.77-1.00) and 0.87 (0.74-1.00), respectively. CONCLUSION: The novel EPiC prognostic model that incorporates clinical information and commonly used biochemical tests, such as AST and CK, can be used to predict mortality in children with EVD.

Evaluating the Clinical Impact of a Novel Pediatric Emergency Medicine Curriculum on Asthma Outcomes in Belize.

BACKGROUND: Respiratory-related complaints prompt most pediatric visits to Karl Heusner Memorial Hospital Authority's (KHMHA) Emergency Department (ED) in Belize. We developed and taught a novel pediatric respiratory emergencies module for generalist practitioners there. We assessed the curriculum's clinical impact on pediatric asthma emergency management. OBJECTIVE: This study assesses the clinical impact of a pediatric emergency medicine curriculum on management of pediatric asthma emergencies at KHMHA in Belize City, Belize. METHODS: We conducted a randomized chart review of pediatric (aged 2-16 y) visits for asthma-related diagnosis at the KHMHA ED between 2015 and 2018 to assess the training module's clinical impact. Primary outcomes included time to albuterol and steroids. Secondary outcomes included clinical scoring tool (Pediatric Respiratory Assessment Measure [PRAM]) usage, ED length of stay, usage of chest radiography, return visit within 7 days, and hospital admission rates. Kaplan-Meier survival analysis and Cox proportional hazard regression were used. RESULTS: Two hundred eighty-three pediatric asthma-related diagnoses met our inclusion criteria. The patients treated by trained and untrained physician groups were demographically and clinically similar. The time to albuterol was significantly faster in the trained (intervention) group compared with the untrained (control) physician group when evaluating baseline of the group posttraining (P < 0.05). However, the time to steroids did not reach statistical significance posttraining (P = 0.93). The PRAM score utilization significantly increased among both control group and intervention group. The untrained physician group was more likely to use chest radiography or admit patients. The trained physician group had higher return visit rates within 7 days and shorter ED length of stay, but this did not reach statistical significance. CONCLUSIONS: The curriculum positively impacted clinical outcomes leading to earlier albuterol administration, increased PRAM score use, obtaining less chest radiographs, and decreased admission rates. The timeliness of systemic steroid administration was unaffected.

Comparative Effectiveness of an In-Person and a Virtual Basic Emergency Care Instructor Course.

Background: Resource limited settings have an ongoing need for access to quality emergency care. The World Health Organization - International Committee of the Red Cross Basic Emergency Care (BEC) course is one mechanism to address this need. Training of BEC trainers has been challenging due to barriers including cost, travel logistics, scheduling, and more recently, social distancing regulations related to the coronavirus pandemic. Objective: We seek to determine if an online virtual format is an effective way to train additional trainers while overcoming these barriers. Methods: The BEC Training-of-Trainers (ToT) course was adapted to a virtual format and delivered entirely online. Participants were assessed with a multiple choice pre- and post-test and completed a course feedback form upon completion. Results from the virtual course were then compared to the results from an in-person ToT course. Findings: The in-person course pre- and post-tests were completed by 121 participants with a pre-test mean of 87% (range 60-100%) and a post-test mean of 95% (range: 75-100; p < 0.05). Virtual course pre- and post-tests by 27 participants were analyzed with a pre-test mean of 89% (range 75-100%) and a post-test mean of 96% (range: 79-100; p < 0.05). No difference in test improvements between the courses was detected (z = -0.485; p = 0.627). The course feedback was completed by 93 in-person participants and 28 virtual participants. Feedback survey responses were similar for all questions except for course length, with in-person participant responses trending towards the course being too long. Conclusions: A virtual format BEC ToT course is effective, feasible, and acceptable. When compared to an in-person course, no difference was detected in nearly all metrics for the virtual format. Utilizing this format for future courses can assist in scaling both the BEC ToT and, by extension, the BEC course globally, particularly in regions facing barriers to in-person training.

Risk Prediction Score for Pediatric Patients with Suspected Ebola Virus Disease.

Rapid diagnostic tools for children with Ebola virus disease (EVD) are needed to expedite isolation and treatment. To evaluate a predictive diagnostic tool, we examined retrospective data (2014-2015) from the International Medical Corps Ebola Treatment Centers in West Africa. We incorporated statistically derived candidate predictors into a 7-point Pediatric Ebola Risk Score. Evidence of bleeding or having known or no known Ebola contacts was positively associated with an EVD diagnosis, whereas abdominal pain was negatively associated. Model discrimination using area under the curve (AUC) was 0.87, which outperforms the World Health Organization criteria (AUC 0.56). External validation, performed by using data from International Medical Corps Ebola Treatment Centers in the Democratic Republic of the Congo during 2018-2019, showed an AUC of 0.70. External validation showed that discrimination achieved by using World Health Organization criteria was similar; however, the Pediatric Ebola Risk Score is simpler to use.

Appendicitis Following Blunt Abdominal Trauma: An Illustrative Case.

Acute appendicitis is the most common abdominal surgical emergency, with an average of 7-9% of individuals developing the condition within their lifetime.1 While cases of acute traumatic appendicitis are rare, medical literature supports their plausibility with the most famous case stretching back to the controversial 1926 death of stunt performer, Harry Houdini. Several mechanisms have been proposed by which blunt abdominal trauma results in acute appendicitis. In this review, we describe a young, otherwise healthy male, who developed epigastric abdominal pain after being struck in the abdomen while wrestling with his cousin of similar age. The patient was found to have peri-appendiceal inflammatory change, appendiceal mural thickening and edema consistent with acute uncomplicated appendicitis.

Development and assessment of novel virtual COVID-19 trainer-of trainers course implemented by an academic-humanitarian partnership.

BACKGROUND: In response to the coronavirus disease (COVID-19) pandemic, Project HOPE®, an international humanitarian organization, partnered with Brown University to develop and deploy a virtual training-of-trainers (TOT) program to provide practical knowledge to healthcare stakeholders. This study is designed to evaluate this TOT program. OBJECTIVE: The goal of this study is to assess the effectiveness of this educational intervention in enhancing knowledge on COVID-19 concepts and to present relative change in score of each competency domains of the training. METHODS: The training was created by interdisciplinary faculty from Brown University and delivered virtually. Training included eight COVID-19 specific modules on infection prevention and control, screening and triage, diagnosis and management, stabilization and resuscitation, surge capacity, surveillance, and risk communication and community education. The assessment of knowledge attainment in each of the course competency domain was conducted using 10 question pre-and post-test evaluations. Paired t-test were used to compare interval knowledge scores in the overall cohort and stratified by WHO regions. TOT dissemination data was collected from in-country partners by Project Hope. RESULTS: Over the period of 7 months, 4,291 personnel completed the TOT training in 55 countries, including all WHO regions. Pre-test and post-test were completed by 1,198 and 706 primary training participants, respectively. The mean scores on the pre-test and post-test were 68.45% and 81.4%, respectively. The mean change in score was 11.72%, with P value <0.0005. All WHO regions had a statistically significant improvement in their score in post-test. The training was disseminated to 97,809 health workers through local secondary training. CONCLUSION: Innovative educational tools resulted in improvement in knowledge related to the COVID-19 pandemic, significantly increasing the average score on knowledge assessment testing. Academic - humanitarian partnerships can serve to implement and disseminate effective education rapidly across the globe.

Epidemiology and Clinical Characteristics of Emergency Department Patients with COVID-19 in a Rhode Island Healthcare System.

BACKGROUND: Rhode Island (RI) has been severely impacted by the COVID-19 pandemic. This study aims to describe emergency department (ED) patients with COVID-19 within the largest healthcare system in RI. METHODS: A retrospective electronic medical record review of 1,209 adult patients evaluated and diagnosed with COVID-19 in 4 EDs during the first peak (March 15, 2020 to May 16, 2020) was conducted. Sociodemographic, clinical, management, and ED disposition information were summarized. RESULTS: Median age of patients was 55 years (IQR 40-69), 55.2% were male, and 47.8% were Hispanic/Latinx. Over half of the patients (60.5%) were admitted to the hospital. Supplemental oxygen was used by 32.2%. CONCLUSION: This study presents the clinical and sociodemographic characteristics of ED patients with COVID-19 presenting to the largest healthcare system in Rhode Island. Continued analysis is warranted to provide further insight into the trends in this pandemic.

COVID-19 in Pediatric Patients: Observations from the Initial Phase of the Global Pandemic in Rhode Island.

OBJECTIVE: To describe characteristics of children undergoing SARS-CoV-2 testing during the initial wave of infections in Rhode Island. METHODS: This is a descriptive study of 729 children tested for SARS-CoV-2 at four emergency departments April 9 to May 7, 2020 in Rhode Island. Demographic information and symptoms were cataloged for those tested. RESULTS: 81 (11%) children tested positive for SARS-CoV-2. 94% of positive children were symptomatic. 74% of positive cases had constitutional symptoms and 72% had upper respiratory symptoms. While only 34% of those tested were Hispanic, 68% of the SARS-CoV-2- positive cases occurred in Hispanic children. CONCLUSION: This study details the pediatric population's experience during the first wave of the pandemic in Rhode Island. It could inform testing allocation strategies in healthcare settings. It also highlights vulnerable populations in need of further public health support in our state.

A Pediatric Emergency Medicine Refresher Course for Generalist Healthcare Providers in Belize: Respiratory Emergencies.

Audience and type of curriculum: This is a refresher curriculum utilizing multiple methods of education to augment the skills of generalist healthcare providers in low- and middle-income countries (LMICs) in the identification and stabilization of pediatric respiratory emergencies. Our audience of implementation was Belizean generalist providers. Length of curriculum: Nine hours. Introduction: In the pediatric population, early recognition and stabilization can improve patient outcomes. Compared with many Western systems that rely on specialists and even subspecialists, in many lower-resource settings, generalists provide most emergency medical care. The purpose of this module is to present a curriculum focused on the identification and stabilization of common pediatric respiratory emergencies for general practitioners (physicians and nurses) working in the acute care setting. Our aim is to provide a care framework and refresher training for the management of pediatric respiratory emergencies for providers who may regularly see the acutely ill pediatric patient but who may not have had recent or any extensive teaching in the management of acute pediatric airway management, bronchiolitis, pneumonia, and asthma. Educational Goals: This curriculum presents a refresher course in recognizing and stabilizing pediatric acute respiratory complaints for generalist healthcare providers practicing in LMICs. Our goal is to implement this curriculum in the small LMIC of Belize. This module focuses on common respiratory complaints, including asthma, bronchiolitis, pneumonia and acute airway management. Educational Methods: The educational strategies used in this curriculum include didactic lectures, medical simulation, small-group sessions, and a skills lab. Research Methods: We scored written pretests before and posttests after intervention and retested participants to evaluate for knowledge retention. Participants provided qualitative feedback on the module. Results: We taught 26 providers. Twenty-one providers completed the posttest and eight completed the retest. The mean test scores improved from 8.3 ± 2.8 in the pretest to 9.7 ± 1.3 to the posttest (mean difference = 1.4; P = 0.027). The mean test score at pretest was 8.0 ± 4.0, which increased to 9.9 ± 2.5 at retest four months later (mean difference = 1.9, P = 0.049). Fifteen (71.4%) participants found the course "extremely useful," and 28 (28.5%) participants "very useful." Discussion: This curriculum is an effective and well-received training tool for Belizean generalist providers. Although limited by sample size and 20% attrition for the retest, there was a statistically significant improvement in test performance. We believe that our pilot in Belize shows that this type of refresher course could be useful for teaching generalist providers in LMICs to optimize care of the acutely ill pediatric patient with respiratory ailment. Evaluation of other modules in this curriculum, application of the curriculum in other locations, and measuring clinical patient outcomes will be included in future investigations. Topics: Medical simulation, rapid cycle deliberate practice (RCDP), Belize, bronchiolitis, pneumonia, asthma, airway, respiratory distress, low- and middle-income country (LMIC), collaboration, global health.

Assessment of Attitudes Toward the Emergency Triage System in Belize.

Objective. Triage in resource-limited settings (RLS) improves outcomes. Emergency Triage Assessment and Treatment (ETAT) is a simple triage algorithm that improves assessment and initial management of children in RLS. In Belize, pediatric triage varies with setting, from a 5-level Emergency Severity Index (ESI) used at the National Referral Hospital to a lack of triage at government health centers (GHC). Most data on ETAT implementation are in settings where no triage system existed; data on how to integrate ETAT into existing, heterogeneous triage systems are lacking. The aim of this study is to explore health care providers' (HCPs) attitudes toward the current triage system prior to national pediatric triage process implementation. Methods. A qualitative study was performed via convenience sampling of HCPs who participated in an ETAT training course using focus groups immediately and 1 year after an initial ETAT training. Focus groups were digitally recorded and transcribed. Three coders analyzed all transcripts to identify emerging themes. Constant comparison analysis was performed until achieving thematic saturation. Results. The following principal themes emerged: (1) importance of triage education and implementation to standardize and improve communication; (2) major limitations of ESI include its complexity, lack of pediatric-specific criteria, and dependence on equipment not consistently available; and (3) desire to implement a simple, low-resource pediatric-specific triage system. Conclusions. Participants believe triage education and process implementation is essential to improve communication and pediatric emergency care. Simple, low-resource pediatric-specific triage systems, like ETAT, may improve utilization by providing faster recognition and improved care for acutely ill children.

Childhood malnutrition within the indigenous Wayuú children of northern Colombia.

Malnutrition contributes to nearly half of all preventable deaths in children under the age of five. While the burden of disease is heaviest in Sub-Saharan Africa, South, and Southeast Asia, malnutrition in Latin America remains high, especially within indigenous communities. This study evaluates the prevalence of malnutrition and its relationship with access to healthcare resources within 172 indigenous Wayuú communities in La Guajira, Colombia. Healthcare workers administered a health questionnaire and collected anthropometric measurements on all children 6 months to 5 years of age within the Wayuú households. These data were utilised to calculate the prevalence of acute malnutrition, stunting, and underweight. Of all surveyed Wayuú children, 22.9% and 18.3% met criteria for moderate and severe malnutrition, 33.4% and 28.1% met criteria for moderate and severe stunting, and 28.1% and 16.6% were moderately and severely underweight. Across all categories, malnourished children were older, less likely to have had a medical professional present at birth, less likely to have received medical care after birth, and more likely to have been born in a non-medical, community setting. The prevalence of malnutrition is much higher than national levels in Colombia. This population requires urgent assistance to address their disproportionately high rates of malnutrition.

Evaluation of International Classification of Diseases, Ninth Revision, Clinical Modification Codes for reporting methicillin-resistant Staphylococcus aureus infections at a hospital in Illinois.

BACKGROUND: States, including Illinois, have passed legislation mandating the use of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for reporting healthcare-associated infections, such as methicillin-resistant Staphylococcus aureus (MRSA). OBJECTIVE: To evaluate the sensitivity of ICD-9-CM code combinations for detection of MRSA infection and to understand implications for reporting. METHODS: We reviewed discharge and microbiology databases from July through August of 2005, 2006, and 2007 for ICD-9-CM codes or microbiology results suggesting MRSA infection at a tertiary care hospital near Chicago, Illinois. Medical records were reviewed to confirm MRSA infection. Time from admission to first positive MRSA culture result was evaluated to identify hospital-onset MRSA (HO-MRSA) infections. The sensitivity of MRSA code combinations for detecting confirmed MRSA infections was calculated using all codes present in the discharge record (up to 15); the effect of reviewing only 9 diagnosis codes, the number reported to the Centers for Medicare and Medicaid Services, was also evaluated. The sensitivity of the combination of diagnosis codes for detection of HO-MRSA infections was compared with that for community-onset MRSA (CO-MRSA) infections. RESULTS: We identified 571 potential MRSA infections with the use of screening criteria; 403 (71%) were confirmed MRSA infections, of which 61 (15%) were classified as HO-MRSA. The sensitivity of MRSA code combinations was 59% for all confirmed MRSA infections when 15 diagnoses were reviewed compared with 31% if only 9 diagnoses were reviewed (P < .001). The sensitivity of code combinations was 33% for HO-MRSA infections compared with 62% for CO-MRSA infections (P < .001). CONCLUSIONS: Limiting analysis to 9 diagnosis codes resulted in low sensitivity. Furthermore, code combinations were better at revealing CO-MRSA infections than HO-MRSA infections. These limitations could compromise the validity of ICD-9-CM codes for interfacility comparisons and for reporting of healthcare-associated MRSA infections.

Orofacial clefts in the National Birth Defects Prevention Study, 1997-2004.

Orofacial clefts are among the most common types of birth defects, but their clinical presentation has not been well described in a geographically diverse US population. To describe the birth prevalence and phenotype of nonsyndromic clefts, we used data from the National Birth Defects Prevention Study (NBDPS), a multi-site, population-based, case-control study aimed at identifying genetic and environmental risk factors for birth defects. Included in the study were infants born during 1997-2004 with a cleft lip (CL), cleft lip with cleft palate (CLP), or cleft palate (CP). Infants with clefts associated with recognized single-gene disorders, chromosome abnormalities, holoprosencephaly, or amniotic band sequence were excluded. A total of 3,344 infants with nonsyndromic orofacial clefts were identified, including 751 with CL, 1,399 with CLP, and 1,194 with CP, giving birth prevalence estimates of 0.3, 0.5, and 0.4/1,000 live births, respectively. Among infants with CLP where cleft laterality was specified, about twice as many had unilateral vs. bilateral involvement, while for CL there were over 10 times as many with unilateral versus bilateral involvement. Involvement was most often left-sided. About one-quarter of infants with CP had Pierre Robin sequence. Over 80% of infants had an isolated orofacial cleft. Among infants with CL or CLP, heart, limb, and other musculoskeletal defects were most commonly observed, while heart, limb, and central nervous system defects were most common among infants with CP. Better understanding of the birth prevalence and phenotype may help guide clinical care as well as contribute to an improved understanding of pathogenesis.

Randomized, double-blind, placebo-controlled trial of effects of enteral iron supplementation on anemia and risk of infection during surgical critical illness.

BACKGROUND: Critical illness is characterized by hypoferremia, iron-deficient erythropoiesis (IDE), and anemia. The relative risks and benefits of iron supplementation in this setting are unknown. METHODS: Anemic, critically ill surgical patients with an expected intensive care unit length of stay (ULOS) >or= 5 days were randomized to either enteral iron supplementation (ferrous sulfate 325 mg three times daily) or placebo until hospital discharge. Outcomes included hematocrit, iron markers (i.e., serum concentrations of iron, ferritin, and erythrocyte zinc protoporphyrin [eZPP]), red blood cell (RBC) transfusion, transfusion rate (mL RBC/study day), nosocomial infection, antibiotic days, study length of stay (LOS), ULOS, and death. Iron-deficient erythropoiesis was defined as an elevated eZPP concentration. RESULTS: Two hundred patients were randomized; 97 received iron, and 103 received placebo. Socio-demographics, baseline acuity, hematocrit, and iron markers were similar in the two groups. No differences were observed between the iron and placebo groups with respect to either hematocrit or iron markers following up to 28 days. However, patients treated with iron were significantly less likely to receive an RBC transfusion (29.9% vs. 44.7%, respectively; p = 0.03) and had a significantly lower transfusion rate (22.0 mL/day vs. 29.9 mL/day; p = 0.03). Subgroup analysis revealed that these differences were observed in patients with baseline IDE only. Iron and placebo groups did not differ with respect to incidence of infection (46.8% vs. 48.9%; p = 0.98), antibiotic days (14 vs. 16; p = 0.45), LOS (14 vs. 16 days; p = 0.24), ULOS (12 vs. 14 days; p = 0.69), or mortality rate (9.4% vs. 9.9%; p = 0.62). CONCLUSIONS: Enteral iron supplementation of anemic, critically ill surgical patients does not increase the risk of infection and may benefit those with baseline IDE by decreasing the risk of RBC transfusion. A trial comparing enteral and parenteral iron supplementation in this setting is warranted (ClinicalTrials.gov number, NCT00450177).
