What are the risk factors for death among children with pneumonia in low- and middle-income countries? A systematic review.

Background: Knowledge of the risk factors for and causes of treatment failure and mortality in childhood pneumonia is important for prevention, diagnosis, and treatment at an individual and population level. This review aimed to identify the most important risk factors for mortality among children aged under ten years with pneumonia. Methods: We systematically searched MEDLINE, EMBASE, and PubMed for observational and interventional studies reporting risk factors for mortality in children (aged two months to nine years) in low- and middle-income countries (LMICs). We screened articles according to specified inclusion and exclusion criteria, assessed risk of bias using the EPHPP framework, and extracted data on demographic, clinical, and laboratory risk factors for death. We synthesized data descriptively and using Forest plots and did not attempt meta-analysis due to the heterogeneity in study design, definitions, and populations. Findings: We included 143 studies in this review. Hypoxaemia (low blood oxygen level), decreased conscious state, severe acute malnutrition, and the presence of an underlying chronic condition were the risk factors most strongly and consistently associated with increased mortality in children with pneumonia. Additional important clinical factors that were associated with mortality in the majority of studies included particular clinical signs (cyanosis, pallor, tachypnoea, chest indrawing, convulsions, diarrhoea), chronic comorbidities (anaemia, HIV infection, congenital heart disease, heart failure), as well as other non-severe forms of malnutrition. Important demographic factors associated with mortality in the majority of studies included age <12 months and inadequate immunisation. Important laboratory and investigation findings associated with mortality in the majority of studies included: confirmed Pneumocystis jirovecii pneumonia (PJP), consolidation on chest x-ray, pleural effusion on chest x-ray, and leukopenia. Several other demographic, clinical and laboratory findings were associated with mortality less consistently or in a small numbers of studies. Conclusions: Risk assessment for children with pneumonia should include routine evaluation for hypoxaemia (pulse oximetry), decreased conscious state (e.g. AVPU), malnutrition (severe, moderate, and stunting), and the presence of an underlying chronic condition as these are strongly and consistently associated with increased mortality. Other potentially useful risk factors include the presence of pallor or anaemia, chest indrawing, young age (<12 months), inadequate immunisation, and leukopenia.

Can child pneumonia in low-resource settings be treated without antibiotics? A systematic review & meta-analysis.

Background: WHO guidelines recommend the use of antibiotics for all cases of pneumonia in children, despite the majority being caused by viruses. We performed a systematic review and meta-analysis to determine which children aged 2-59 months with WHO-defined fast breathing pneumonia, if any, can be safely treated without antibiotics. Methods: We systematically searched medical databases for articles published in the last 20 years. We included both observational and interventional studies that compared antibiotics to no antibiotics in children aged 2-59 months diagnosed with fast breathing pneumonia in low- and middle-income countries (LMICs). We screened articles according to specified inclusion and exclusion criteria, and assessed for risk of bias using the Effective Public Health Practice Project (EPHPP) framework. Overall, we included 13 studies in this review. We performed a meta-analysis of four included studies comparing amoxicillin to placebo. Results: Most children with fast breathing pneumonia will have a good outcome, regardless of whether or not they are treated with antibiotics. Meta-analysis of four RCTs comparing amoxicillin to placebo for children with pneumonia showed higher risk of treatment failure in the placebo group (odds ratio OR 1.40, 95% confidence interval CI = 1.00-1.96). We did not identify any child pneumonia subgroups in whom antibiotics can be safely omitted. Limited data suggest that infants with clinically-diagnosed bronchiolitis are a particular low-mortality group who may be safely treated without antibiotics in some contexts. Conclusions: Children with WHO-defined fast breathing pneumonia in LMICs should continue to be treated with antibiotics. Future studies should seek to identify which children stand to benefit most from antibiotic therapy, and identify those in whom antibiotics may not be required, and in which circumstances.

Continuous Positive Airway Pressure (CPAP) for severe pneumonia in low- and middle-income countries: A systematic review of contextual factors.

Background: Continuous positive airway pressure (CPAP) may have a role in reducing the high mortality in children less than 5 years with World Health Organization (WHO) severe pneumonia. More evidence is needed to understand important contextual factors that impact on implementation, effectiveness, and safety in low resource settings. Methods: We conducted a systematic review of Medline, Embase and Pubmed (January 2000 to August 2020) with terms of "pneumonia", "CPAP" and "child". We included studies that provided original clinical or non-clinical data on the use of CPAP in children (28 days-4 years) with pneumonia in low- or middle-income countries. We used standardised tools to assess study quality, and grade levels of evidence for clinical conclusions. Results are presented as a narrative synthesis describing context, intervention, and population alongside outcome data. Results: Of 902 identified unique references, 23 articles met inclusion criteria, including 6 randomised controlled trials, one cluster cross over trial, 12 observational studies, 3 case reports and 1 cost-effectiveness analysis. There was significant heterogeneity in patient population, with wide range in mortality among participants in different studies (0%-55%). Reporting of contextual factors, including staffing, costs, and details of supportive care was patchy and non-standardised. Current evidence suggests that CPAP has a role in the management of infants with bronchiolitis and as escalation therapy for children with pneumonia failing standard-flow oxygen therapy. However, CPAP must be implemented with appropriate staffing (including doctor oversight), intensive monitoring and supportive care, and technician and infrastructure capacity. We provide practical guidance and recommendations based on available evidence and published expert opinion, for the adoption of CPAP into routine care in low resource settings and for reporting of future CPAP studies. Conclusions: CPAP is a safe intervention in settings that can provide intensive monitoring and supportive care, and the strongest evidence for a benefit of CPAP is in infants (aged less than 1 year) with bronchiolitis. The available published evidence and clinical experience can be used to help facilities assess appropriateness of implementing CPAP, guide health workers in refining selection of patients most likely to benefit from it, and provide a framework for components of safe and effective CPAP therapy.

Which children with chest-indrawing pneumonia can be safely treated at home, and under what conditions is it safe to do so? A systematic review of evidence from low- and middle-income countries.

Background: WHO pneumonia guidelines recommend that children (aged 2-59 months) with chest indrawing pneumonia and without any "general danger sign" can be treated with oral amoxicillin without hospital admission. This recommendation was based on trial data from limited contexts whose generalisability is unclear. This review aimed to identify which children with chest-indrawing pneumonia in low- and middle-income countries can be safely treated at home, and under what conditions is it safe to do so. Methods: We searched MEDLINE, EMBASE, and PubMed for observational and interventional studies of home-based management of children (aged 28 days to four years) with chest-indrawing pneumonia in low- or middle-income countries. Results: We included 14 studies, including seven randomised trials, from a variety of urban and rural contexts in 11 countries. Two community-based and two hospital-based trials in Pakistan and India found that home treatment of chest-indrawing pneumonia was associated with similar or superior treatment outcomes to hospital admission. Evidence from trials (n = 3) and observational (n = 6) studies in these and other countries confirms the acceptability and feasibility of home management of chest-indrawing pneumonia in low-risk cases, so long as safeguards are in place. Risk assessment includes clinical danger signs, oxygen saturation, and the presence of comorbidities such as undernutrition, anaemia, or HIV. Pulse oximetry is a critical risk-assessment tool that is currently not widely available and can identify severely ill patients with hypoxaemia otherwise possibly missed by clinical assessment alone. Additional safeguards include caregiver understanding and ability to return for review. Conclusions: Home treatment of chest-indrawing pneumonia can be safe but should only be recommended for children confirmed to be low-risk and in contexts where appropriate care and safety measures are in place.

Neighbourhood Income Inequality and General Psychopathology at 3-Years of Age.

Background: Several studies have linked neighbourhood environment to preschool-aged children's behavioural problems. Income inequality is an identified risk factor for mental health among adolescents, however, little is known as to whether this relationship extends to younger children. Objective: To explore the association between neighbourhood-level income inequality and general psychopathology problems among preschool-aged children. Methods: We analyzed data from the All Our Families (AOF) longitudinal cohort located in Calgary, Canada at 3-years postpartum. The analytical sample consisted of 1615 mother-preschooler dyads nested within 184 neighbourhoods. Mothers completed the National Longitudinal Survey of Children and Youth Child Behaviour Checklist (NLSCY-CBCL), which assessed internalizing and externalizing symptoms. Income inequality was assessed via the Gini coefficient, which quantifies the unequal distribution of income in society. Mixed effects linear regression assessed the relationship between neighbourhood income inequality and preschooler's general psychopathology. Results: The mean Gini coefficient across the 184 neighbourhoods was 0.33 (SD = 0.05; min, max: 0.20-0.56). In the fully adjusted model income inequality was not associated with general psychopathology in children ß = 0.07 (95%CI: -0.29, 0.45). Neighbourhood environment accounted for 0.5% of the variance in psychopathology in children. Conclusion: The lack of significant findings may be due to a lack of statistical power in the study. Future studies should investigate this relationship with appropriately powered studies, and over time, to assess if income inequality is a determinant of preschooler psychopathology in Canada.

Contexte: Plusieurs études ont relié l'environnement du quartier aux problèmes de comportement des enfants d'âge préscolaire. L'inégalité du revenu est un facteur de risque identifié pour la santé mentale chez les adolescents, pourtant, on ne sait pas encore si cette relation s'étend aux enfants plus jeunes. Objectif: Explorer l'association entre l'inégalité du revenu au niveau du quartier et les problèmes de psychopathologie générale chez les enfants d'âge préscolaire. Méthodes: Nous avons analysé les données de la cohorte longitudinale All Our Families (AOF) située à Calgary, Canada, à 3 ans de postpartum. L'échantillon analytique consistait en 1615 dyades mère-enfant d'âge préscolaire logées dans 184 quartiers. Les mères ont rempli l'Enquête longitudinale nationale sur les enfants et les jeunes et la liste de contrôle du comportement de l'enfant (ELNEJ-LCCE), qui évaluaient les symptômes d'internalisation et d'externalisation. L'inégalité du revenu était évaluée par le coefficient Gini, qui quantifie la distribution inégale du revenu dans la société. La régression linéaire à effets mixtes a évalué la relation entre l'inégalité du revenu du quartier et la psychopathologie générale de enfants d'âge préscolaire. Résultats: Le coefficient Gini moyen dans les 184 quartiers était de 0,33 (ET = 0,05; min, max : 0,20­0,56). Dans le modèle complétement ajusté, l'inégalité du revenu n'était pas associée à la psychopathologie générale des enfants ß = 0,07 (IC à 95 % −0,29 à 0,45). L'environnement du quartier représentait 0,5 % de la variance de psychopathologie chez les enfants. Conclusion: L'absence de résultats significatifs peut être attribuable au manque de puissance statistique de l'étude. Les futures études devraient investiguer cette relation avec des études d'une puissance appropriée, et avec le temps, évaluer si l'inégalité du revenu est déterminante de la psychopathologie des enfants d'âge préscolaire au Canada.

Wellbeing, burnout and substance use amongst medical students: A summary of results from nine countries.

OBJECTIVE: There has been increasing interest in the physical health, mental wellbeing and burnout afflicting medical students over recent years. This paper describes the overall results from phase two of an international study including a further nine countries across the world. METHODS: We sampled large groups of medical students in nine countries at the same time and with exactly the same method in order to aid direct comparison of demographics, burnout and mental wellbeing through validated instruments. RESULTS: A total of 4,942 medical students from these countries participated in this study. Around 68% of respondents screened positive for mild psychiatric illness using the General Health Questionnaire-12. Around 81% and 78% of respondents were found to be disengaged or exhausted respectively using the Oldenburg Burnout Inventory. Around 10% were found to be CAGE positive and 14% reported cannabis use. The main source of stress reported by medical students was their academic studies, followed by relationships, financial difficulties and housing issues. CONCLUSION: Cultural, religious and socioeconomic factors within each country are important and understanding their effects is fundamental in developing successful local, regional and national initiatives. Further quantitative and qualitative research is required to confirm our results, clarify their causes and to develop appropriate preventative strategies.

Cultural variations in wellbeing, burnout and substance use amongst medical students in twelve countries.

High levels of stress, burnout, and symptoms of poor mental health have been well known among practicing doctors for a number of years. Indeed, many health systems have formal and informal mechanisms to offer support and treatment where needed, though this varies tremendously across cultures. There is increasing evidence that current medical students, our doctors of the future, also report very high levels of distress, burnout, and substance misuse. We sampled large groups of medical students in 12 countries at the same time and with exactly the same method in order to aid direct comparison. 3766 students responded to our survey across five continents in what we believe is a global first. Our results show that students in all 12 countries report very high levels of 'caseness' on validated measures of psychiatric symptoms and burnout. Rates of substance misuse, often a cause of or coping mechanism for this distress, and identified sources of stress also varied across cultures. Variations are strongly influenced by cultural factors. Further quantitative and qualitative research is required to confirm our results and further delineate the causes for high rates of psychiatric symptoms and burnout. Studies should also focus on the implementation of strategies to safeguard and identify those most at risk.

Wellbeing and mental health amongst medical students in Canada.

Across the world there is significant evidence that medical students have high levels of mental ill-health and psychological distress with subsequent concerning effects on personal and occupational functioning. In Canada, recent studies have demonstrated worrying levels of burnout and depressive symptoms among practising doctors. In common with other countries, Canadian medical students are also subject to a high-pressure environment - with long clinical weeks and significant stressors - and these soon-to-be doctors have been previously shown to already demonstrate high levels of burnout. We surveyed 69 medical students at the Cumming School of Medicine, Calgary regarding their wellbeing and mental health. 26% of the students had been diagnosed with a mental health condition prior to medical school, while 36% reported currently seeing a professional regarding their mental ill-health, with anxiety disorders forming the most commonly reported conditions. 83% reported their studies as a significant source of stress. 22% tested as CAGE positive and a number of students reported using other substances. 70% of medical students met specified case criteria for exhaustion on the Oldenburg Burnout Inventory. These findings speak to the need for access to mental health services, evidence-based individual counselling, and inclusive activities that fit within organisational frameworks to better improve the mental health and wellbeing of medical students in Canada.

Advancing family-centred care in child and adolescent mental health: a critical review of the literature.

Family-centred care (FCC) is a key factor in increasing health and related system responsiveness to the needs of children and families; unfortunately, it is an unfamiliar service model in children's mental health. This critical review of the literature addresses three key questions: What are the concepts, characteristics and principles of FCC in the context of delivering mental health services to children? What are the enablers, barriers and demonstrated benefits to using a family-centred approach to care in children's mental health? And how can we facilitate moving an FCC model forward in children's mental health? A range of databases was searched for the years 2000­2011, for children ages zero to 18 years. Articles were selected for inclusion if a family-centred approach to care was articulated and the context was the intervention and treatment side of the mental healthcare system. This literature review uncovered a multiplicity of terms and concepts, all closely related to FCC. Two of the most frequently used terms in children's mental health are family centred and family focused, which have important differences, particularly in regard to how the family is viewed. Initial benefits to FCC include improved child and family management skills and function, an increased stability of living situation, improved cost-effectiveness, increased consumer and family satisfaction and improved child and family health and well-being. Significant challenges exist in evaluating FCC because of varying interpretations of its core concepts and applications. Nonetheless, a shared understanding of FCC in a children's mental health context seems possible, and examples can be found of best practices, enablers and strategies, including opportunities for innovative policy change to overcome barriers.
