    (2023-09) Tan, Chantal D.; Vermont, Clementien L.; Zachariasse, Joany M.; Zavadska, Dace; On behalf of PERFORM consortium (Personalised Risk assessment in febrile children to optimize Real-life Management across the European Union); Balode, Anda; Bārzdiņa, Arta; Gardovska, Dace; Grāvele, Dagne; Grope, Ilze; Meiere, Anija; Nokalna, Ieva; Pavāre, Jana; Pučuka, Zanda; Sidorova, Aleksandra; Urbāne, Urzula Nora; Rīga Stradiņš University
    Children constitute 6–10% of all patients attending the emergency department (ED) by emergency medical services (EMS). However, discordant EMS use in children occurs in 37–61% with fever as an important risk factor. We aimed to describe EMS utilisation among febrile children attending European EDs. This study is part of an observational multicentre study assessing management and outcome in febrile children up to 18 years (MOFICHE) attending twelve EDs in eight European countries. Discordant EMS use was defined as the absence of markers of urgency including intermediate/high triage urgency, advanced diagnostics, treatment, and admission in children transferred by EMS. Multivariable logistic regression analyses were performed for the association between (1) EMS use and markers of urgency, and (2) patient characteristics and discordant EMS use after adjusting all analyses for the covariates age, gender, visiting hours, presenting symptoms, and ED setting. A total of 5464 (15%, range 0.1–42%) children attended the ED by EMS. Markers of urgency were more frequently present in the EMS group compared with the non-EMS group. Discordant EMS use occurred in 1601 children (29%, range 1–59%). Age and gender were not associated with discordant EMS use, whereas neurological symptoms were associated with less discordant EMS use (aOR 0.2, 95%CI 0.1–0.2), and attendance out of office hours was associated with more discordant EMS use (aOR 1.6, 95%CI 1.4–1.9). Settings with higher percentage of self-referrals to the ED had more discordant EMS use (p < 0.05). Conclusion: There is large practice variation in EMS use in febrile children attending European EDs. Markers of urgency were more frequently present in children in the EMS group. However, discordant EMS use occurred in 29%. Further research is needed on non-medical factors influencing discordant EMS use in febrile children across Europe, so that pre-emptive strategies can be implemented. What is Known: •Children constitute around 6–10% of all patients attending the emergency department by emergency medical services. •Discordant EMS use occurs in 37–61% of all children, with fever as most common presenting symptom for discordant EMS use in children. What is New: •There is large practice variation in EMS use among febrile children across Europe with discordance EMS use occurring in 29% (range 1–59%), which was associated with attendance during out of office hours and with settings with higher percentage of self-referrals to the ED. •Future research is needed focusing on non-medical factors (socioeconomic status, parental preferences and past experience, healthcare systems, referral pathways, out of hours services provision) that influence discordant EMS use in febrile children across Europe.

    (2022-09) Borensztajn, Dorine M.; Hagedoorn, Nienke N.; Carrol, Enitan D.; von Both, Ulrich; Emonts, Marieke; van der Flier, Michiel; de Groot, Ronald; Herberg, Jethro; Kohlmaier, Benno; Levin, Michael; Lim, Emma; Maconochie, Ian K.; Martinon-Torres, Federico; Nijman, Ruud G.; Pokorn, Marko; Rivero-Calle, Irene; Tsolia, Maria; van der Velden, Fabian J.S.; Vermont, Clementien; Zavadska, Dace; Zenz, Werner; Zachariasse, Joany M.; Moll, Henriette A.; Department of Paediatrics
    We aimed to describe characteristics and management of children with comorbidities attending European emergency departments (EDs) with fever. MOFICHE (Management and Outcome of Fever in children in Europe) is a prospective multicentre study (12 European EDs, 8 countries). Febrile children with comorbidities were compared to those without in terms of patient characteristics, markers of disease severity, management, and diagnosis. Comorbidity was defined as a chronic underlying condition that is expected to last > 1 year. We performed multivariable logistic regression analysis, displaying adjusted odds ratios (aOR), adjusting for patient characteristics. We included 38,110 patients, of whom 5906 (16%) had comorbidities. Most common comorbidities were pulmonary, neurologic, or prematurity. Patients with comorbidities more often were ill appearing (20 versus 16%, p < 0.001), had an ED-Paediatric Early Warning Score of > 15 (22 versus 12%, p < 0.001), or a C-reactive protein > 60 mg/l (aOR 1.4 (95%CI 1.3–1.6)). They more often required life-saving interventions (aOR 2.7, 95% CI 2.2–3.3), were treated with intravenous antibiotics (aOR 2.3, 95%CI 2.1–2.5), and were admitted to the ward (aOR 2.2, 95%CI 2.1–2.4) or paediatric intensive care unit (PICU) (aOR 5.5, 95% CI 3.8–7.9). They were more often diagnosed with serious bacterial infections (aOR 1.8, 95%CI 1.7–2.0), including sepsis/meningitis (aOR 4.6, 95%CI 3.2–6.7). Children most at risk for sepsis/meningitis were children with malignancy/immunodeficiency (aOR 14.5, 8.5–24.8), while children with psychomotor delay/neurological disease were most at risk for life-saving interventions (aOR 5.3, 4.1–6.9) or PICU admission (aOR 9.7, 6.1–15.5). Conclusions: Our data show how children with comorbidities are a population at risk, as they more often are diagnosed with bacterial infections and more often require PICU admission and life-saving interventions.What is Known:• While children with comorbidity constitute a large part of ED frequent flyers, they are often excluded from studies.What is New:• Children with comorbidities in general are more ill upon presentation than children without comorbidities.• Children with comorbidities form a heterogeneous group; specific subgroups have an increased risk for invasive bacterial infections, while others have an increased risk of invasive interventions such as PICU admission, regardless of the cause of the fever.

    Sex differences in febrile children with respiratory symptoms attending European emergency departments : An observational multicenter study
    (2022-08-03) Tan, Chantal D.; el Ouasghiri, Soufiane; von Both, Ulrich; Carrol, Enitan D.; Emonts, Marieke; van der Flier, Michiel; de Groot, Ronald; Herberg, Jethro; Kohlmaier, Benno; Levin, Michael; Lim, Emma; Maconochie, Ian K.; Martinon-Torres, Federico; Nijman, Ruud G.; Pokorn, Marko; Rivero-Calle, Irene; Tsolia, Maria; Vermont, Clementien L.; Zenz, Werner; Zavadska, Dace; Moll, Henriette A.; Zachariasse, Joany M.; Department of Paediatrics
    Objective To assess sex differences in presentation and management of febrile children with respiratory symptoms attending European Emergency Departments. Design and setting An observational study in twelve Emergency Departments in eight European countries. Patients Previously healthy children aged 0-<18 years with fever (≥ 38°C) at the Emergency Department or in the consecutive three days before Emergency Department visit and respiratory symptoms were included. Main outcome measures The main outcomes were patient characteristics and management defined as diagnostic tests, treatment and admission. Descriptive statistics were used for patient characteristics and management stratified by sex. Multivariable logistic regression analyses were performed for the association between sex and management with adjustment for age, disease severity and Emergency Department. Additionally, subgroup analyses were performed in children with upper and lower respiratory tract infections and in children below five years. Results We included 19,781 febrile children with respiratory symptoms. The majority were boys (54%), aged 1-5 years (58%) and triaged as low urgent (67%). Girls presented less frequently with tachypnea (15% vs 16%, p = 0.002) and increased work of breathing (8% vs 12%, p<0.001) compared with boys. Girls received less inhalation medication than boys (aOR 0.82, 95% CI 0.74-0.90), but received antibiotic treatment more frequently than boys (aOR 1.09, 95% CI 1.02-1.15), which is associated with a higher prevalence of urinary tract infections. Amongst children with a lower respiratory tract infection and children below five years girls received less inhalation medication than boys (aOR 0.77, 95% CI 0.66-0.89; aOR 0.80, 95% CI 0.72-0.90). Conclusions Sex differences concerning presentation and management are present in previously healthy febrile children with respiratory symptoms presenting to the Emergency Department. Future research should focus on whether these differences are related to clinicians' attitudes, differences in clinical symptoms at the time of presentation and disease severity.

    Shock Index in the early assessment of febrile children at the emergency department : a prospective multicentre study
    (2022-02) Hagedoorn, Nienke N.; Zachariasse, Joany M.; Borensztajn, Dorine; Adriaansens, Elise; Von Both, Ulrich; Carrol, Enitan D.; Eleftheriou, Irini; Emonts, Marieke; Van Der Flier, Michiel; De Groot, Ronald; Herberg, Jethro Adam; Kohlmaier, Benno; Lim, Emma; Maconochie, Ian; Martinón-Torres, Federico; Nijman, Ruud Gerard; Pokorn, Marko; Rivero-Calle, Irene; Tsolia, Maria; Zavadska, Dace; Zenz, Werner; Levin, Michael; Vermont, Clementien; Moll, Henriette A.; Department of Paediatrics
    Objective: (1) To derive reference values for the Shock Index (heart rate/systolic blood pressure) based on a large emergency department (ED) population of febrile children and (2) to determine the diagnostic value of the Shock Index for serious illness in febrile children. Design/setting: Observational study in 11 European EDs (2017-2018). Patients: Febrile children with measured blood pressure. Main outcome measures: Serious bacterial infection (SBI), invasive bacterial infection (IBI), immediate life-saving interventions (ILSIs) and intensive care unit (ICU) admission. The association between high Shock Index (>95th centile) and each outcome was determined by logistic regression adjusted for age, sex, referral, comorbidity and temperature. Additionally, we calculated sensitivity, specificity and negative/positive likelihood ratios (LRs). Results: Of 5622 children, 461 (8.2%) had SBI, 46 (0.8%) had IBI, 203 (3.6%) were treated with ILSI and 69 (1.2%) were ICU admitted. High Shock Index was associated with SBI (adjusted OR (aOR) 1.6 (95% CI 1.3 to 1.9)), ILSI (aOR 2.5 (95% CI 2.0 to 2.9)), ICU admission (aOR 2.2 (95% CI 1.4 to 2.9)) but not with IBI (aOR: 1.5 (95% CI 0.6 to 2.4)). For the different outcomes, sensitivity for high Shock Index ranged from 0.10 to 0.15, specificity ranged from 0.95 to 0.95, negative LRs ranged from 0.90 to 0.95 and positive LRs ranged from 1.8 to 2.8. Conclusions: High Shock Index is associated with serious illness in febrile children. However, its rule-out value is insufficient which suggests that the Shock Index is not valuable as a screening tool for all febrile children at the ED.
