Assessment of adherence to the 2020 Surviving Sepsis Campaign guidelines for fluid resuscitation in children with suspected septic shock in paediatric emergency departments: a prospective multicentre study.

BACKGROUND: Paediatric sepsis is the leading cause of death in children under 5 years. No studies have evaluated the application of the Surviving Sepsis Campaign 2020 (SSC-2020) guidelines in paediatric emergency departments (PEDs). OBJECTIVE: To assess physician adherence to the SSC-2020 fluid resuscitation guidelines in children with suspected septic shock in PEDs. METHODS: This was a prospective multicentre observational study conducted in 21 French hospitals over 5 sequential weeks, between November 2021 and March 2022. Children with suspected septic shock and who received antimicrobial therapy within 72 hours were included. Primary outcome was SSC-2020 fluid resuscitation guidelines adherence (low 0-24%; moderate 25-74%; high 75-100%) according to: bolus volume of 10-20 mL/kg each, exclusive administration of balanced crystalloids at 1 and 24 hours of management, and initiation of fluid resuscitation within 1 hour of septic shock recognition. RESULTS: 63 children were included. 10 (16%) children had severe sepsis and 2 (3%) met the definition of septic shock. Compared with the SSC-2020 guidelines, 43 (68%) patients received boluses of 10-20 mL/kg; fluid resuscitation was initiated within 1 hour of septic shock recognition in 42 (76%) cases; balanced crystalloids were the only fluids administrated in 35 (56%) and 34 (55%) children at 1 and 24 hours of management, respectively. Main barriers reported by physicians were difficult intravenous access (43%), lack of team training (29%), workload constraints (28%), and absence or out-of-date protocols (24%). CONCLUSIONS: This study found high adherence for fluid resuscitation initiation but moderate adherence for bolus volume and fluid choice. TRIAL REGISTRATION NUMBER: NCT05066464.

Medical students' perception of simulation-based assessment in emergency and paediatric medicine: a focus group study.

BACKGROUND: Although simulation-based assessment (SBA) is being implemented in numerous medical education systems, it is still rarely used for undergraduate medical students in France. Objective structured clinical examinations (OSCEs) will be integrated into the national medical curriculum in 2021. In 2016 and 2017, we created a mannequin SBA to validate medical students' technical and psychometric skills during their emergency medicine and paediatric placements. The aim of our study was to determine medical students' perceptions of SBA. METHODS: We followed the grounded theory framework to conduct a qualitative study. A total of 215 students participated in either a paediatric or an emergency medicine simulation-based course with a final assessment. Among the 215 participants, we randomly selected forty students to constitute the focus groups. In the end, 30 students were interviewed. Data were coded and analysed by two independent investigators within the activity theory framework. RESULTS: The analyses found four consensual themes. First, the students perceived that success in the SBA provided them with self-confidence and willingness to participate in their hospital placements (1). They considered SBA to have high face validity (2), and they reported changes in their practice after its implementation (3). Nevertheless, they found that SBA did not help with their final high-stakes assessments (4). They discussed three other themes without reaching consensus: stress, equity, and the structure of SBA. After an analysis with activity theory, we found that students' perceptions of SBA underlined the contradictions between two systems of training: hospital and medical. We hypothesise that a specific role and place for SBA should be defined between these two activity systems. CONCLUSION: The students perceived that SBA would increase self-confidence in their hospital placements and emphasise the general skills required in their future professional environment. However, they also reported that the assessment method might be biased and stressful. Our results concerning a preimplementation mannequin SBA and OSCE could provide valuable insight for new programme design and aid in improving existing programmes. Indeed, SBA seems to have a role and place between hospital placements and medical schools.

[Pediatric lumbar puncture: indications, execution and complications]. / La ponction lombaire chez l'enfant : indications, réalisation et complications.

Pediatric lumbar puncture : indications, execution and complications. Lumbar puncture (LP) is a commonly performed procedure with specific indications and technical considerations in pediatrics. The principal indication is for the diagnosis of central nervous system infection, but in case of meningitis in infants, nuchal rigidity may be absent and the clinical picture is more likely to be marked by axial hypotonia associated with abnormal behavior and/or a bulging fontanel. Pharmacological agents and non-pharmacological techniques (reassuring approach, distraction, presence of a parent) should be used whenever possible, to create successful environmental conditions for the completion of the LP procedure in childhood. During the procedure, the LP needle should be moved forward slightly and perpendicularly to the patient's back, and the stylet should be removed regularly to check CSF reflux, as resistance related to the spinal ligaments and dura mere are often absent in young children. In children, post-LP headaches may be prevented by the use of atraumatic and/or the smallest LP needle, and the replacement of the stylet prior to needle removal.

La ponction lombaire chez l'enfant : indications, réalisation et complications. La ponction lombaire est un acte diagnostique et thérapeutique dont les indications ainsi que la procédure du geste présentent des spécificités chez l'enfant. L'indication principale est celui du diagnostic d'une méningite, mais chez le jeune nourrisson une raideur de nuque est souvent absente et le tableau clinique est marqué par une hypotonie axiale associée à des anomalies du comportement et/ou une fontanelle bombée. L'information de la famille et la mise en condition de l'enfant visant à créer les conditions environnementales propices à la réussite du geste est indispensable et comprend des moyens non médicamenteux et médicamenteux. Au cours du geste, l'aiguille de ponction doit être enfoncée perpendiculairement au plan vertical du dos du patient et le stylet doit être régulièrement retiré pour visualiser un reflux de liquide céphalorachidien, le ressaut indiquant le passage du ligament jaune et de la dure-mère étant souvent manquant chez le jeune enfant. Enfin, la prévention des céphalées post-ponction lombaire chez l'enfant repose principalement sur l'utilisation d'aiguilles plus fines ou atraumatiques et le replacement du stylet en fin de geste.

Incidence of IgA vasculitis in children estimated by four-source capture-recapture analysis: a population-based study.

Objectives: The aim was to describe the epidemiological characteristics of childhood IgA vasculitis (IgAV) defined by the EULAR/PRINTO/Paediatric Rheumatology European Society criteria in a population-based sample from France and ascertain its incidence over 3 years by a four-source capture-recapture analysis. Methods: Cases were prospectively collected in Val de Marne county, a suburb of Paris, with 263 874 residents <15 years old. Children with incident IgAV living in this area from 2012 to 2014 were identified by four sources of case notification (emergency departments, paediatrics departments, private-practice paediatricians and general practitioners). Annual incidence was calculated, and a capture-recapture analysis was used with log-linear modelling to estimate case-finding completeness. Results: We identified 147 incident cases [78 boys; mean age 6.5 (s.d.:2.6) years]. The annual incidence (95% CI) was 18.6 (13.6, 24.5)/100 000 children. Although only 10% of children were exclusively identified by non-hospital sources, the completeness of case finding was 62%, with an undercount-corrected annual incidence (95% CI) of 29.9 (23.7, 37.3)/100 000 children. The annual distribution of diagnoses consistently showed a trough in summer months; 72% of children had infectious symptoms (mainly upper respiratory tract) a few days before IgAV onset; and 23% had a North African background. Conclusion: Our study supports secular and geospatial stability in childhood IgAV incidence and adds further indirect evidence for a possible role of a ubiquitous, non-emerging infectious trigger. Incidence studies from understudied areas are needed to disentangle the role of genetic factors better. Capture-recapture analysis suggests that a substantial portion of IgAV cases may remain unrecognized in epidemiological surveys.

Google Glass for Residents Dealing With Pediatric Cardiopulmonary Arrest: A Randomized, Controlled, Simulation-Based Study.

OBJECTIVES: To determine whether real-time video communication between the first responder and a remote intensivist via Google Glass improves the management of a simulated in-hospital pediatric cardiopulmonary arrest before the arrival of the ICU team. DESIGN: Randomized controlled study. SETTING: Children's hospital at a tertiary care academic medical center. SUBJECTS: Forty-two first-year pediatric residents. INTERVENTIONS: Pediatric residents were evaluated during two consecutive simulated pediatric cardiopulmonary arrests with a high-fidelity manikin. During the second evaluation, the residents in the Google Glass group were allowed to seek help from a remote intensivist at any time by activating real-time video communication. The residents in the control group were asked to provide usual care. MEASUREMENTS AND MAIN RESULTS: The main outcome measures were the proportion of time for which the manikin received no ventilation (no-blow fraction) or no compression (no-flow fraction). In the first evaluation, overall no-blow and no-flow fractions were 74% and 95%, respectively. During the second evaluation, no-blow and no-flow fractions were similar between the two groups. Insufflations were more effective (p = 0.04), and the technique (p = 0.02) and rate (p < 0.001) of chest compression were more appropriate in the Google Glass group than in the control group. CONCLUSIONS: Real-time video communication between the first responder and a remote intensivist through Google Glass did not decrease no-blow and no-flow fractions during the first 5 minutes of a simulated pediatric cardiopulmonary arrest but improved the quality of the insufflations and chest compressions provided.

An innovative pedagogic course combining video and simulation to teach medical students about pediatric cardiopulmonary arrest: a prospective controlled study.

UNLABELLED: Compliance by residents in pediatrics to pediatric resuscitation guidelines is low. In many French faculties, a 1-h traditional lecture is still used to educate medical students about pediatric cardiopulmonary arrest (CPA). We developed an innovative pedagogic course combining a 23-min video and 3-h simulation exercises to improve knowledge and skills of medical students. A prospective controlled study was conducted. Medical student knowledge was tested before, just after, and 6-12 months after the innovative course and compared to that of a cohort who attended the traditional lecture. A high-fidelity mannequin simulator simulating cardiopulmonary arrest was used to assess and compare the skills of the study and control groups. Costs of the courses were evaluated; 809 of 860 (94 %) medical students were assessed for knowledge. Six to 12 months after the courses, the median score was significantly higher for the innovative group than that for the traditional lecture group (p < 0.001). In terms of skills, student in the innovative group scored higher on the performance score than the control group (p < 0.01). The innovative course was 24 times more expensive. CONCLUSION: Combination of video and simulation allows better retention of knowledge than a traditional lecture and leads to better compliance to resuscitation guidelines. WHAT IS KNOWN: • Compliance by residents to pediatric resuscitation guidelines is low. • We developed an innovative pedagogic course combining an educational video and simulation. What is new: • Knowledge retention after the innovative course was better than after a traditional lecture. • Sixty-six students tested on their skills demonstrated better compliance to resuscitation guidelines.

[PCR testing for Bordetella pertussis in household contacts as a diagnostic tool for atypical whooping cough in unvaccinated young infants]. / La recherche de Bordetella pertussis par PCR chez les parents permet de diagnostiquer la coqueluche atypique chez les jeunes nourrissons non vaccinés.

INTRODUCTION: False-negative findings of polymerase chain reaction (PCR) for genuine pertussis as well as the numerous atypical forms of whooping cough make it difficult to diagnose this disease in young babies. METHODS: For two years, real-time PCR was performed to test for Bordetella pertussis in 86 infants younger than 6 months hospitalized for apnea or paroxysmal and/or vomiting cough and in 205 of their household contacts, whether or not they coughed. RESULTS: Group 1 included 30 infants for whom PCR detected B. pertussis (25 of whom were also RSV+). PCR was also positive for at least one household contact in 25/30 families. This group included 16 babies with apnea and 12 who developed a whooping cough during follow-up. Group 2 comprised 12 infants whose PCR was negative while at least one household contact had positive results. Five of these infants had severe apnea and 6 developed a whooping cough. Group 3 included 44 infants (28 RSV +) for whom PCR was negative in the index case and in the household contacts: none developed a whooping cough during follow-up. Only 3 of the 54 positive household contacts had a paroxysmal cough or a typical whooping cough and 12 had no cough at all. CONCLUSION: Positive PCR in a household contact, symptomatic or not, is helpful for the diagnosis of atypical whooping cough in young infants.

[Respiratory syncytial virus in hospitalized children. A 3-year study]. / La fréquence du virus respiratoire syncytial et des autres virus respiratoires dans les hospitalisations de l'enfant. Une enquête de 3 ans.

OBJECTIVE: To assess the prevalence of respiratory syncytial virus (RSV) and other important respiratory viruses in children hospitalized in a pediatric hospital in Paris (France) during a 3-year period (2001 to 2004). PATIENTS AND METHODS: The study included all patients aged 8 days to 16 years admitted from the community through emergency department with bronchiolitis, pneumonia, upper respiratory tract infection, asthma or acute isolated fever and who had nasopharyngeal samples taken for viral identification by immunofluorescence (RSV, influenza, para-influenza, and adenoviruses). RESULTS: A virus was found in 464 of 1208 patients with samples taken. RSV was identified in 375 patients, 74% of them younger than 6 months and diagnosed with bronchiolitis. RSV was isolated more often than any other virus, overall and for all diagnoses except "isolated fever," for which influenza was more frequent. In patients aged 24 months or older, influenza and RSV were identified at the same frequency. Overall, influenza virus was found in 53 patients, adenoviruses in 24 and para-influenza viruses in 11. CONCLUSION: RSV was the respiratory virus isolated most often, even in older children, during this 3-year study. The relative rarity of hospitalizations due to para-influenza viruses is characteristic of this area, compared with some other countries.

Pertussis and respiratory syncytial virus infections.

During the winter 2005-2006, all infants <4 months of age admitted for bronchiolitis or acute respiratory tract infection in a tertiary care pediatric hospital in Paris were tested for respiratory syncytial virus (RSV) and pertussis with real-time polymerase-chain reaction (RT-PCR). A positive pertussis-PCR was found in 14/90 (16%) infants infected with RSV and in 5/30 negative for RSV. Similar clinical symptoms were found in all RSV-positive infants with or without pertussis co-infection. Most infants (73%) were not vaccinated against pertussis, and the other children had received one or two injections. In conclusion, pertussis-RSV co-infection is common in young infants, and pertussis-PCR should be used, whenever available.

Serum procalcitonin and other biologic markers to distinguish between bacterial and aseptic meningitis.

OBJECTIVE: To identify the biologic tests that best distinguish between bacterial and aseptic meningitis in an emergency department (ED). STUDY DESIGN: All children hospitalized for bacterial meningitis between 1995 and 2004 or for aseptic meningitis between 2000 and 2004 were included in a retrospective cohort study. Predictive values of blood (C-reactive protein, procalcitonin [PCT], white blood cell [WBC] count, neutrophil count) and cerebrospinal fluid (CSF) findings (protein, glucose, WBC count, neutrophil count) available in the ED were determined. Tests with the best predictive value were identified by using univariate and multivariate analyses and ROC curves comparison. RESULTS: Among the 167 patients included, 21 had bacterial meningitis. The CSF gram-stain and bacterial antigen test had 86% and 60% sensitivity rates, respectively. PCT (>/=0.5 ng/mL) and CSF protein (>/=0.5 g/L) were the best biologic tests, with 89% and 86% sensitivity rates, 89% and 78% specificity rates, adjusted odds ratios of 108 (95% CI, 15-772) and 34 (95% CI, 5-217), and areas under the ROC curves of 0.95 and 0.93, respectively. CONCLUSION: PCT and CSF protein had the best predictive value to distinguish between bacterial and aseptic meningitis in children.
