Introduction: Acute diarrhea remains a leading cause of morbidity and mortality with over 6.3 billion cases and 1.3 million deaths annually. Despite the existence of standardized guidelines for diarrhea management, wide variability in clinical practice exists, particularly in resource-limited settings. The goal of this study was to qualitatively explore how diarrhea management in Bangladesh varies according to resource availability, clinical setting, and provider roles. Methodology: This was a secondary analysis of a cross-sectional qualitative study conducted in three diverse hospital settings (district hospital, subdistrict hospital, and specialty diarrhea research hospital) in Bangladesh. A total of eight focus group discussions with nurses and physicians were conducted. Applied thematic analysis was used to identify themes regarding variations in diarrhea management. Results: Of the 27 focus group participants, 14 were nurses and 13 doctors; 15 worked in a private diarrhea specialty hospital and 12 worked in government district or subdistrict hospitals. Several key themes emerged from the qualitative data analysis: 1) priorities in the clinical assessment of diarrhea 2) use of guidelines versus clinical judgment; 3) variability in clinician roles and between clinical settings influences care delivery; 4) impact of resource availability on diarrhea management; and 5) perceptions of community health workers’ role in diarrhea management. Conclusions: Findings from this study may aid in informing interventions to improve and standardize diarrhea management in resource-constrained settings. Resource availability, practices regarding diarrhea assessment and treatment, provider experience, and variability in provider roles are essential considerations when developing clinical tools in low- and middle- income countries.
Diarrheal disease accounts for more than one million deaths annually in patients over 5 years of age. Although most patients can be managed with oral rehydration solution, patients with severe dehydration require resuscitation with intravenous fluids. Scoring systems to assess dehydration have been empirically derived and validated in children under 5 years, but none have been validated for patients over 5 years. In this study, a prospective cohort of 2,172 patients over 5 years presenting with acute diarrhea to International Centre for Diarrhoeal Disease Research, Dhaka Hospital, Bangladesh, were assessed for clinical signs of dehydration. The percent difference between presentation and posthydration stable weight determined severe (≥ 9%), some (3-9%), or no (< 3%) dehydration. An ordinal regression model was derived using clinical signs and demographics and was then converted to a 13-point score to predict none (score of 0-3), some (4-6), or severe (7-13) dehydration. The Novel, Innovative Research for Understanding Dehydration in Adults and Kids (NIRUDAK) Score developed by our team included age, sex, sunken eyes, radial pulse, respiration depth, skin turgor, and vomiting episodes in 24 hours. Accuracy of the NIRUDAK Score for predicting severe dehydration, as measured by the area under the receiver operating characteristic curve, was 0.76 (95% confidence interval = 0.73-0.78), with a sensitivity of 0.78 and a specificity of 0.61. Reliability was also robust, with an Inter-Class Correlation Coefficient of 0.88 (95% confidence interval = 0.84-0.91). This study represents the first empirically derived and internally validated scoring system for assessing dehydration in children ≥ 5 years and adults with acute diarrhea in a resource-limited setting.
Rwanda's ambitious Human Resources for Health (HRH) program comes to an end this year, having made great strides towards achieving its aim to create a large, diverse and competent health workforce, and will have graduated over 4,500 healthcare professionals since its inception in 2012. The HRH program was based on strong collaborative relationships between Rwandan and United States academic institutions and faculty and now stands poised to enter a new phase focused on sustaining the many gains achieved. Fostering career development of new Rwandan faculty and building health research capacity are key components to sustaining the mutually beneficial partnerships that have been forged over the past seven years, with the goal of creating strong Rwandan health researchers that can advance knowledge of best practices for patient care and public health, appropriate to the Rwandan context and other resource-limited settings.
Abstract Introduction Disaster and humanitarian responders are at-risk of experiencing a wide range of physical and psychological health conditions, from minor injuries to chronic mental health problems and fatalities. This article reviews the current literature on the major health outcomes of responders to various disasters and conflicts in order to better inform individuals of the risks and to inform deploying agencies of the health care needs of responders. Methods In March 2014, an EMBASE search was conducted using pre-defined search criteria. Two reviewers screened the resultant 2,849 abstracts and the 66 full-length manuscripts which are included in the review. Results The majority of research on health outcomes of responders focused on mental health (57 of 66 articles). Posttraumatic stress disorder (PTSD) and depression were the most studied diagnoses with prevalence of PTSD ranging from 0%-34% and depression from 21%-53%. Physical health outcomes were much less well-studied and included a wide range of environmental, infectious, and traumatic conditions such as heat stroke, insect bites, dermatologic, gastrointestinal, and respiratory diseases, as well as burns, fractures, falls, and other traumatic injuries. Conclusions The prevalence of mental health disorders in responders may vary more and be higher than previously suggested. Overall health outcomes of responders are likely poorly monitored and under-reported. Improved surveillance systems and risk mitigation strategies should be employed in all disaster and conflict responses to better protect individual responders. Garbern SC , Ebbeling LG , Bartels SA .

In 2016, diarrheal disease was the eighth leading cause of mortality globally accounting for over 1.6 million deaths with the majority of deaths in adults and children over 5 years. This study aims to investigate the clinical, sociodemographic, and environmental risk factors associated with common bacterial acute diarrhea among adults and children over 5. Data were collected from March 2019 to March 2020 in patients over 5 years presenting with acute gastroenteritis at icddr,b. Stool samples were collected from each patient for culture and polymerase chain reaction (PCR) testing. Bivariate associations between independent variables and stool-testing indicating bacterial etiology were calculated. This analysis included 2,133 diarrheal patients of whom a bacterial enteropathogen was identified in 1,537 (72%). Detection of bacteria was associated with: younger age (OR 0.92; 95% CI: 0.88-0.96), lower mean arterial pressure (OR 0.84; 95% CI: 0.79-0.89), heart rate (OR 1.06; 95% CI: 1.01-1.10), percentage dehydration (OR 1.33; 95% CI: 1.13-1.55), respiration rate (OR 1.23; 95% CI: 1.04-1.46), lower mid-upper arm circumference (OR 0.97; 95% CI: 0.94-0.99), confused/lethargic mental status (OR 1.85; 95% CI: 1.11-3.25), rice watery stool (OR 1.92; 95% CI: 1.54-2.41), and vomiting more than three times in the past 24 hours (OR 1.30; 95% CI: 1.06-1.58). Higher monthly income (OR 0.92; 95% CI: 0.86-0.98), > 8 years of education (OR 0.79; 95% CI: 0.63-1.00), and having more than five people living at home (OR 0.80; 95% CI: 0.66-0.98) were associated with lower odds of bacterial diarrhea. These findings may help guide the development of predictive tools to aid in identifying patients with bacterial diarrhea for timely and appropriate use of antibiotics.
Background: Diarrheal illness is a leading cause of antibiotic use for children in low- and middle-income countries. Determination of diarrhea etiology at the point-of-care without reliance on laboratory testing has the potential to reduce inappropriate antibiotic use. Methods: This prospective observational study aimed to develop and externally validate the accuracy of a mobile software application (‘App’) for the prediction of viral-only etiology of acute diarrhea in children 0–59 months in Bangladesh and Mali. The App used a previously derived and internally validated model consisting of patient-specific (‘present patient’) clinical variables (age, blood in stool, vomiting, breastfeeding status, and mid-upper arm circumference) as well as location-specific viral diarrhea seasonality curves. The performance of additional models using the ‘present patient’ data combined with other external data sources including location-specific climate, data, recent patient data, and historical population-based prevalence were also evaluated in secondary analysis. Diarrhea etiology was determined with TaqMan Array Card using episode-specific attributable fraction (AFe) >0.5. Results: Of 302 children with acute diarrhea enrolled, 199 had etiologies above the AFe threshold. Viral-only pathogens were detected in 22% of patients in Mali and 63% in Bangladesh. Rotavirus was the most common pathogen detected (16% Mali; 60% Bangladesh). The present patient+ viral seasonality model had an AUC of 0.754 (0.665–0.843) for the sites combined, with calibration-in-the-large α = −0.393 (−0.455––0.331) and calibration slope β = 1.287 (1.207–1.367). By site, the present patient+ recent patient model performed best in Mali with an AUC of 0.783 (0.705–0.86); the present patient+ viral seasonality model performed best in Bangladesh with AUC 0.710 (0.595–0.825). Conclusions: The App accurately identified children with high likelihood of viral-only diarrhea etiology. Further studies to evaluate the App’s potential use in diagnostic and antimicrobial stewardship are underway.

Injuries cause significant morbidity and mortality in sub-Saharan African countries such as Rwanda. These burdens may be compounded by limited access to intravenous (IV) resuscitation fluids such as crystalloids and blood products. This study evaluates the association between emergency department (ED) intravenous volume resuscitation and mortality outcomes in adult trauma patients treated at the University Teaching Hospital-Kigali (UTH- K). Data were abstracted using a structured protocol for a random sample of ED patients treated during periods from 2012 to 2016. Patients under 15 years of age were excluded. Data collected included demographics, clinical aspects, types of IV fluid resuscitation provided and outcomes. The primary outcome was facility-based mortality. Descriptive statistics were used to explore characteristics of the population. Kampala Trauma Scores (KTS) were used to control for injury severity. Magnitudes of effects were quantified using multivariable regression models adjusted for gender, KTS, time period, clinical interventions, presence of head injury and transfer to a tertiary care centre to yield adjusted odds ratios (aOR) with 95% confidence intervals (CI). From the random sample of 3609 cases, 991 trauma patients were analysed. The median age was 32 [IQR 26, 46] years and 74.3% were male. ED volume resuscitation was given to 50.1% of patients with 43.5% receiving crystalloid and 6.4% receiving crystalloid and packed red blood cell (PRBC) transfusions. The median KTS score was 13 [IQR 12, 13]. In multivariable regression, mortality likelihood was increased in those who received crystalloid (aOR = 4.31, 95%CI 1.24, 15.05, p = 0.022) and PRBC plus crystalloid (aOR = 9.97, 95%CI 2.15,46.17, p = 0.003) as compared to trauma patients not treated with IV resuscitation fluids. Injured ED patients treated with volume resuscitation had higher mortality, which may be due to unmeasured confounding or therapies provided. Further studies on fluid resuscitation in trauma populations in resource-limited settings are needed.
ABSTRACT Background Severe acute respiratory infections (SARIs) are the leading cause of pediatric death globally, particularly in low- and middle-income countries (LMICs). Given the potential rapid clinical decompensation and high mortality rate from SARIs, interventions that facilitate the early care of patients are critical to improving patient outcomes. The aim of this systematic review was to evaluate the impact of emergency care interventions on improving clinical outcomes of pediatric patients with SARIs in LMICs. Methods PubMed, Global Health, and Global Index Medicus electronic databases were searched to identify peer-reviewed clinical trials or studies with comparator groups published before November 2020. All studies which evaluated acute and emergency care interventions on clinical outcomes for children (29 days to 19 years) with SARIs conducted in LMICs were included. Given the heterogeneity of interventions and outcomes, a narrative synthesis was performed. Bias was assessed using the Risk of Bias 2 and Risk of Bias in Non-Randomized Studies of Interventions. Results 20,583 studies were screened, with 99 meeting criteria for final inclusion. The most common conditions studied were pneumonia or acute lower respiratory infection (61.6%) and bronchiolitis (29.3%). The majority of studies evaluated medications (80.8%), followed by respiratory support (14.1%) and supportive care (5%). The strongest evidence of benefit was found for respiratory support interventions such as improved medical oxygen systems to decrease risk of death. Results were notably inconclusive on the utility of continuus positive airway pressure (CPAP). Mixed results were found for interventions for bronchiolitis, although possible benefit was found for hypertonic nebulized saline to decrease hospital length of stay. Early use of adjuvant treatments such as Vitamin A, D, and zinc for pneumonia and bronchiolitis did not appear to have convincing evidence of benefit on clinical outcomes. Conclusions While the burden of SARI in pediatric populations is high, few emergency care (EC) interventions have high quality evidence for benefit on clinical outcomes in LMICs. Respiratory support interventions have the strongest evidence for decreasing hospital length of stay and mortality and improvement of clinical status. Further research on the use of CPAP in diverse settings and populations is needed. A stronger evidence base for EC interventions for children with SARI, including metrics on the timing of interventions, is greatly needed.
