Background: Malaria is a leading cause of morbidity and mortality in refugee children in high-transmission parts of Africa. Characterizing the clinical features of malaria in refugees can inform approaches to reduce its burden., Methods: The study was conducted in a high-transmission region of northern Zambia hosting Congolese refugees. We analyzed surveillance data and hospital records of children with severe malaria from refugee and local sites using multivariable regression models and geospatial visualization., Results: Malaria prevalence in the refugee settlement was similar to the highest burden areas in the district, consistent with the local ecology and leading to frequent rapid diagnostic test stockouts. We identified 2197 children hospitalized for severe malaria during the refugee crisis in 2017 and 2018. Refugee children referred from a refugee transit center (n = 63) experienced similar in-hospital mortality to local children and presented with less advanced infection. However, refugee children from a permanent refugee settlement (n = 110) had more than double the mortality of local children (P < .001), had lower referral rates, and presented more frequently with advanced infection and malnutrition. Distance from the hospital was an important mediator of the association between refugee status and mortality but did not account for all of the increased risk., Conclusions: Malaria outcomes were more favorable in refugee children referred from a highly outfitted refugee transit center than those referred later from a permanent refugee settlement. Refugee children experienced higher in-hospital malaria mortality due in part to delayed presentation and higher rates of malnutrition. Interventions tailored to the refugee context are required to ensure capacity for rapid diagnosis and referral to reduce malaria mortality., Competing Interests: Potential conflicts of interest. W.

Background: With the invasion of Ukraine by the Russian Army in February 2022, refugees, the majority of whom are women and children, started fleeing the war to neighbouring countries. Even before the current escalation, the conflict in the eastern part of Ukraine has led to the internal displacement of more than 200,000 children, and many others have experienced attacks, e.g. on schools. This inevitably leads to limitations in health care delivery. During transit, overcrowding, poor shelter and vulnerability may further put refugees at increased risk for infectious diseases. This consensus document aims to provide information and guidance regarding health issues that paediatricians and general practitioners may face when caring for Ukrainian children., Methods: Members of the Migrant Health Reference Group of Paediatrics Switzerland and the Paediatric Infectious Disease Group in Switzerland developed this recommendation between March and April 2022 in a modified Delphi process., Results: A total of 50 recommendations were agreed on with a ≥80% consensus. These include the following topics: i) general aspects, including interpreter services, urgent health needs, personal history and general check-ups; ii) mental health, including how to search for signs of psychological distress without going into traumatic details; iii) vaccinations, including recommendations for evaluation and catch-up; iv) screening for tuberculosis, human immunodeficiency virus, and hepatitis B and C; and v) providing age-appropriate preventive and health service information., Conclusion: This document provides current evidence and guidance when caring for paediatric refugees from Ukraine. The recommendations focus on Switzerland but may well be used in other countries. These are based on current evidence and may need to be adapted to individual situations and once further evidence becomes available.

Background: Subclinical tuberculosis (TB) is well recognized and defined as a disease state with absent or nonrecognized symptoms. The study identifies factors associated with subclinical TB and diagnostic strategies in a low-burden, high-resource country., Methods: Data were collected between December 2013 and November 2019 through the Swiss Pediatric Surveillance Unit (SPSU). Children with culture/molecular confirmed TB, or who were treated with ≥3 antimycobacterial drugs, were included., Results: A total of 138 (80%) children with TB disease were included in the final analysis, of which 43 (31%) were subclinical. The median age of children with subclinical compared to symptomatic TB was 3.7 (interquartile range [IQR] 2.2-7) and 9.7 (IQR 2.7-14.3) years, respectively (P = .003). The cause of investigation for TB was recorded in 31/43 (72.1%) of children with subclinical TB and included contact exposure in 25 (80.6%) of children. In children with subclinical TB, diagnosis was made by a combination of the following abnormal/confirming results: culture/molecular + immunodiagnostic + chest radiography in 12 (27.9%) cases, immunodiagnostic + chest radiography in 19 (44.2%) cases, culture/molecular + chest radiography in 2 (4.7%) cases, culture + immunodiagnostic in 1 (2.3%) case, chest radiography only in 8 (18.6%) cases, and immunodiagnostic only in 1 (2.3%) case., Conclusions: A notable proportion of children with TB had subclinical disease. This highlights the importance of non-symptom-based TB case finding in exposed children and refugees from high-TB-prevalence settings. TB screening in these asymptomatic children should therefore include a combination of immunodiagnostic testing and imaging followed by culture and molecular testing., (© The Author(s) 2021.

Background: Asylum-seeking children represent an increasing and vulnerable group of patients whose health needs are largely unmet. Data on the health care provision to asylum-seeking children in European contexts is scarce. In this study we compare the health care provided to recent asylum-seeking and non-asylum-seeking children at a Swiss tertiary hospital., Methods: We performed a cross-sectional retrospective study in a pediatric tertiary care hospital in Basel, Switzerland. All patients and visits from January 2016 to December 2017 were identified, using administrative and medical electronic health records. The asylum-seeking status was systematically assessed and the patients were allocated accordingly in the two study groups., Results: A total of 202,316 visits by 55,789 patients were included, of which asylum-seeking patients accounted for 1674 (1%) visits by 439 (1%) individuals. The emergency department recorded the highest number of visits in both groups with a lower proportion in asylum-seeking compared to non-asylum-seeking children: 19% (317/1674) and 32% (64,315/200,642) respectively. The median number of visits per patient was 1 (IQR 1-2) in the asylum-seeking and 2 (IQR 1-4) in the non-asylum-seeking children. Hospital admissions were more common in asylum-seeking compared to non-asylum-seeking patients with 11% (184/1674) and 7% (14,692/200,642). Frequent visits (> 15 visits per patient) accounted for 48% (807/1674) of total visits in asylum-seeking and 25% (49,886/200,642) of total visits in non-asylum-seeking patients., Conclusions: Hospital visits by asylum-seeking children represented a small proportion of all visits. The emergency department had the highest number of visits in all patients but was less frequently used by asylum-seeking children. Frequent care suggests that asylum-seeking patients also present with more complex diseases. Further studies are needed, focusing on asylum-seeking children with medical complexity.

Background: In Europe, surveillance and monitoring of pediatric tuberculosis (TB) remains important, particularly in the light of migration in recent years. The aim of the study was to evaluate incidence rates of childhood TB and detailed diagnostic pathways and treatment., Methods: Data were collected through the Swiss Pediatric Surveillance Unit (SPSU) from December 2013 to November 2019. Monthly -notifications are obtained from the 33 pediatric hospitals in the SPSU, and a detailed questionnaire was sent out upon notification. Inclusion criteria were children and adolescents aged up to 15 years with culture- or molecular-confirmed TB disease or for whom a treatment with ≥3 antimycobacterial drugs had been initiated. Data were compared with age-matched notification data from the Swiss Federal Office of Public Health (FOPH)., Results: Of the 172 cases notified to SPSU, a detailed questionnaire was returned for 161 (93%) children, of which 139 met the inclusion criteria. Reasons for exclusion were age >15 years, double reporting, and not fulfilling the criteria for TB disease. During the same time period, 172 pediatric TB cases were reported to the FOPH, resulting in an incidence of 2.1 per 100,000, ranging from 1.4 to 2.8 per year, without a clear trend over time. In the 64 (46.0%) foreign-born children, incidence rates were higher and peaked in 2016, with 13.7 per 100,000 (p = 0.018). The median interval between arrival in Switzerland and TB diagnosis was 5 (IQR 1-21) months, and 80% were diagnosed within 24 months of arrival. In 58% of the cases, TB disease was confirmed by culture or molecular assays. Age >10 years, presence of fever, or weight loss were independent factors associated with confirmed TB., Conclusion: The annual pediatric TB incidence rate only varied among foreign-born children and was highest in 2016 when refugee influx peaked in Europe. Importantly, most foreign-born children with TB were diagnosed within 2 years after arrival in Switzerland. Thus, the early period after arrival in Switzerland is associated with a higher risk of TB disease in children, and this should be considered for screening guidance in refugees., (© 2021 The Author(s) Published by S.

Background: In the last decade an increasing number of asylum-seeking children arrived in Europe and local healthcare systems have been challenged to adapt to their health needs. The aim of this study was to compare the spectrum of disease and management of asylum-seeking and non-asylum-seeking children requiring hospital admission., Methods: This was a retrospective cohort study including health data from recently arrived asylum-seeking and non-asylum-seeking children admitted between January 2016 and December 2017. Data were collected using electronic administrative and medical records., Results: Of 11,794 admissions of 9407 patients, 149 (1%) were asylum-seeking and 11,645 (99%) from non-asylum-seeking children. In asylum-seeking children the median age was 4 years (interquartile range [IQR] 0&ndash;13) with 61% males and in non-asylum-seeking children 4 years (IQR 0&ndash;11) years with 56% males. Respiratory infections accounted for 17&ndash;19% of admissions in both groups. Rare infectious diseases were more frequent in asylum-seeking children (15 vs 7%; difference in proportions 0.08, 95% confidence interval [CI] 0.02&ndash;0.14; p &lt;0.001,). Injuries were more frequent in non-asylum-seeking children (22 vs 13%; difference in proportions 0.09, 95% CI 0.04&ndash;0.014; p &lt;0.01). Admissions for mental health disorders were infrequent but more common in asylum-seeking children (6 vs 3%; difference in proportions 0.03, 95% CI &minus;0.01 &ndash; 0.07; p = 0.02) Prescription of analgesics was lower in asylum-seeking than non-asylum-seeking children (3.4 vs 6.5 accounting units per admission). Antibiotic prescription was comparable in both groups., Conclusion: Asylum-seeking children represent a small number of total admissions. Age distribution and main reason for admission being diseases of the respiratory system were comparable in asylum-seeking and non-asylum-seeking children. Rare infections and mental health disorders are important diseases in asylum-seeking children and require special attention and training of staff working with paediatric asylum seekers.

Background: Migrant health has become an essential part of public health. According to the World Health Organization, many health systems in Europe have not yet adapted adequately to the needs of asylum-seekers, which might result in untimely and inefficient health care for asylum-seeking patients. The aim of this study was to assess the number of preventable hospital admissions and emergency department visits in asylum-seeking and non-asylum-seeking pediatric patients., Methods: This is a retrospective, hospital-based study. The study was done at the University Children's Hospital Basel in Switzerland. Patients admitted or presenting to the emergency department were included and split into the groups of asylum-seeking and non-asylum-seeking patients. All admissions and emergency-department visits were extracted from the administrative electronic health records from 1st Jan 2016-31st Dec 2017. The main outcome was the proportion of admissions due to ambulatory-care-sensitive conditions (which refer to conditions for which admission can be prevented by early interventions in primary care) in asylum-seeking and non-asylum-seeking patients. Ambulatory-care-sensitive conditions were defined by a validated list of ICD-10 codes. The secondary objective was to assess the number of preventable emergency-department visits by asylum-seeking patients defined as proportion of visits with a non-urgent triage score., Results: A total of 75'199 hospital visits were included, of which 63'405 were emergency department visits and 11'794 were admissions. Ambulatory-care-sensitive conditions accounted for 12.1% (18/149) of asylum-seeking and 10.9% (1270/11645) of non-asylum seeking patients' admissions. Among the emergency department visits by asylum-seeking patients, non-urgent conditions accounted for 82.2% (244/297)., Conclusions: Admissions due to ambulatory-care-sensitive conditions are comparable in asylum-seeking and non-asylum-seeking children, suggesting few delayed presentations to ambulatory care facilities. Strategies to prevent non-urgent visits at pediatric emergency department facilities are needed.

Objectives: This study investigated the perspective of asylum-seeking caregivers on the quality of healthcare delivered to their children in a qualitative in-depth interview study. The health of asylum-seeking children is of key interest for healthcare providers, yet knowledge of the perspective of asylum-seeking caregivers when accessing healthcare is limited., Setting: The study took place in a paediatric tertiary care hospital in Basel, Switzerland., Participants: Interviews were done with 13 asylum-seeking caregivers who had presented with their children at the paediatric tertiary care hospital. Nine female and four male caregivers from Tibet, Eritrea, Afghanistan, Syria, Iraq, Albania and Macedonia were included. A diverse sample was chosen regarding cultural and social background, years of residence in Switzerland and reasons for seeking care. A previously developed and pilot-tested interview guide was used for semistructured in-depth interviews between 36 and 92 min in duration. Data analysis and reporting was done according to Consolidated Criteria for Reporting Qualitative Research. The number of interviews was determined by saturation of data., Results: The interviewees described a mismatch of personal competencies and external challenges. Communication barriers and unfamiliarity with new health concepts were reported as challenges. These were aggravated by isolation and concerns about their child's health. The following factors were reported to strongly contribute to satisfaction of healthcare delivery: a respectful and trusting caregiver-provider relationship, the presence of interpreters and immediate availability of treatment., Conclusions: A mismatch of personal competencies and external challenges importantly influences the caregiver-provider relationship. To overcome this mismatch establishment of confidence was identified as a key factor. This can be achieved by availability of interpreter services, sufficient consultation time and transcultural trainings for healthcare workers. Coordination between the family, the government's asylum system and the medical system is required to facilitate this process., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Between 2015 and 2017, an estimated 200,000 to 400,000 children were seeking asylum each year in EU/EEA countries. As access to high-quality health care is important, we collected and compared current recommendations across Europe for a consensus recommendation on medical care for migrant (asylum-seeking and refugee) children. Existing recommendations were collected from published literature and identified through national representatives from paediatric societies of 31 EU/EEA countries through the European Academy of Paediatrics (EAP). Recommendations were systematically extracted and collected in a database. Those mentioned in at least one recommendation were evaluated for inclusion, and evidence on recommendations was specifically identified in literature searches focused on recent evidence from Europe. For eight EU/EEA countries, a national recommendation was identified. Growth and development, vision and hearing impairment, skin and dental problems, immunisations, anaemia, micronutrient deficiency, helminths, hepatitis B and C, human immunodeficiency virus, malaria, schistosomiasis, syphilis, tuberculosis, mental health disorder and sexual health were most frequently mentioned and therefore selected for inclusion in the recommendation.Conclusion: The current document includes general recommendations on ethical standards, use of interpreters and specific recommendations for prevention or early detection of communicable and non-communicable diseases. It may serve as a tool to ensure the fundamental right that migrant children in Europe receive a comprehensive, patient-centred health care.

Background: Migrants and refugees have important health needs and face inequalities in their health status. Health care delivery to this patient group has become a challenging public health focus in high income countries. This paper summarizes current knowledge on health care delivery to migrants and refugees in high-income countries from multiple perspectives., Methods: We performed a systematic literature review including primary source qualitative and quantitative studies between 2000 and 2017. Articles were excluded if the study setting was in low- or middle-income countries or focused on skilled migration. Quality assessment was done for qualitative and quantitative studies separately. Predefined variables were extracted in a standardized form. Authors were approached to provide missing information., Results: Of 185 identified articles, 35 were included in the final analysis. We identified three main topics of challenges in health care delivery: communication, continuity of care and confidence. All but one study included at least one of the three main topics and in 21/35 (60%) all three topics were mentioned. We further developed the 3C model and elaborated the interrelatedness of the three topics. Additional topics identified showed that the specific regional context with legal, financial, geographical and cultural aspects is important and further influences the 3C model., Conclusions: The 3C model gives a simple and comprehensive, patient-centered summary of key challenges in health care delivery for refugees and migrants. This concept is relevant to support clinicians in their day to day practice and in guiding stakeholders in priority setting for refugee and migrant health policies.

The aim of this retrospective study was to describe the epidemiology and spectrum of infections of admitted pediatric refugees and asylum seekers in a tertiary referral hospital in a high-income country in Europe. We identified recent refugees and asylum seekers < 18 years of age admitted to the University Children's Hospital in Basel, Switzerland, in 2015. A retrospective analysis was performed using electronic patient records. We identified 105 admissions in 93 patients with a median age of 5.7 (IQR 2.6-14.5) years. Eritrea, Syria, and Afghanistan were the most frequent countries of origin. The median duration of admission was 4 (IQR 2-6) days with infections and elective surgical interventions being the most common reason (54.8 and 16.1%, respectively). Most infections were airway, skin, and gastrointestinal in 46.4, 20.2, and 11.9%, respectively. The prevalence of tropical infections was 11.9%. The main pathogens identified were influenza A virus (13.8%), Staphylococcus aureus (10.3%), and rhino/enterovirus (10.3%). Previous medical non-infectious conditions were recorded in 13%., Conclusion: The study revealed a high burden of infections in admitted patients mostly caused by well-known pathogens prevalent also in the local population. Both tropical infections and pre-existing non-infectious conditions are also important in admitted patients. Better epidemiological data is required to optimize health care for this medically most vulnerable population in refugee crises. What is Known: • Pediatric refugees and asylum seekers are the most vulnerable population in refugee crises. • Data on health concerns and needs in this population is scarce. What is New: • This is one of the first studies on the epidemiology of pediatric refugees and asylum seekers treated as inpatients in a European high-income country. • The high burden of infections is mostly caused by well-known pathogens prevalent also in the local population.
