Background Based on European recommendations of ESPGHAN/ESPID from 2008, first line therapy for dehydration caused by acute gastroenteritis (AGE) is oral rehydration solution (ORS). In case of oral route failure, nasogastric tube enteral rehydration is as efficient as intra-venous rehydration and seems to lead to fewer adverse events. The primary objective was to describe rehydration strategies used in cases of AGE in pediatric emergency departments (PEDs) in Belgium, France, The Netherlands, and Switzerland. Methods An electronic survey describing a scenario in which a toddler had moderate dehydration caused by AGE was sent to physicians working in pediatric emergency departments. Analytical data were analyzed with descriptive statistics and Kruskal -Wallis Rank test. Results We analyzed 68 responses, distributed as follows: Belgium N = 10, France N = 37, The Netherlands N = 7, and Switzerland N = 14. Oral rehydration with ORS was the first line of treatment for 90% of the respondents. In case of first line treatment failure, intravenous rehydration was preferred by 95% of respondents from France, whereas nasogastric route was more likely to be used by those from Belgium (80%), The Netherlands (100%) and Switzerland (86%). Serum electrolyte measurements were more frequently prescribed in France (92%) and Belgium (80%) than in The Netherlands (43%) and Switzerland (29%). Racecadotril was more frequently used in France, and ondansetron was more frequently used in Switzerland. No respondent suggested routine use of antibiotics. Conclusion We found variations in practices in terms of invasiveness and testing. Our study supports the need for further evaluation and implementation strategies of ESPGHAN/ESPID guidelines. We plan to extend the study throughout Europe with support of the Young ESPID Group. [ABSTRACT FROM AUTHOR]

Background: Diagnosing serious infections in children is challenging, because of the low incidence of such infections and their non-specific presentation early in the course of illness. Prediction rules are promoted as a means to improve recognition of serious infections. A recent systematic review identified seven clinical prediction rules, of which only one had been prospectively validated, calling into question their appropriateness for clinical practice. We aimed to examine the diagnostic accuracy of these rules in multiple ambulatory care populations in Europe., Methods: Four clinical prediction rules and two national guidelines, based on signs and symptoms, were validated retrospectively in seven individual patient datasets from primary care and emergency departments, comprising 11,023 children from the UK, the Netherlands, and Belgium. The accuracy of each rule was tested, with pre-test and post-test probabilities displayed using dumbbell plots, with serious infection settings stratified as low prevalence (LP; <5%), intermediate prevalence (IP; 5 to 20%), and high prevalence (HP; >20%) . In LP and IP settings, sensitivity should be >90% for effective ruling out infection., Results: In LP settings, a five-stage decision tree and a pneumonia rule had sensitivities of >90% (at a negative likelihood ratio (NLR) of < 0.2) for ruling out serious infections, whereas the sensitivities of a meningitis rule and the Yale Observation Scale (YOS) varied widely, between 33 and 100%. In IP settings, the five-stage decision tree, the pneumonia rule, and YOS had sensitivities between 22 and 88%, with NLR ranging from 0.3 to 0.8. In an HP setting, the five-stage decision tree provided a sensitivity of 23%. In LP or IP settings, the sensitivities of the National Institute for Clinical Excellence guideline for feverish illness and the Dutch College of General Practitioners alarm symptoms ranged from 81 to 100%., Conclusions: None of the clinical prediction rules examined in this study provided perfect diagnostic accuracy. In LP or IP settings, prediction rules and evidence-based guidelines had high sensitivity, providing promising rule-out value for serious infections in these datasets, although all had a percentage of residual uncertainty. Additional clinical assessment or testing such as point-of-care laboratory tests may be needed to increase clinical certainty. None of the prediction rules identified seemed to be valuable for HP settings such as emergency departments.
