RESUMEN
OBJECTIVES: To describe the distribution, consequences and potential determinants of time to antibiotics administration in children with community-onset severe bacterial infections (COSBIs). DESIGN: Secondary analysis of the available data from a prospective population-based study from 2009 to 2014. SETTING: An administrative area in western France accounting for 13% of the national pediatric population. PATIENTS: All children from 1 month to 16 years old admitted to a PICU or who died before admission and had a COSBI. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The time to antibiotics was divided into patient interval (from first signs of COSBI to the first medical consultation) and medical interval (from the first consultation to appropriate antibiotics administration). The association between the medical interval and child outcome was studied by a multinomial logistic regression model and the potential determinants of the patient and medical intervals were by a Cox proportional-hazards model. Of the 227 children included (median age 2.1 yr), 22 died (9.7%), and 21 (9.3%) had severe sequelae at PICU discharge. Median patient and medical intervals were 7.0 hours (interquartile range [IQR], 2.0-16.5 hr) and 3.3 hours (IQR, 1.1-12.2 hr), respectively. The last quartile of medical interval was not associated with death (adjusted odds ratio [aOR], 3.7; 95% CI, 0.8-17.5) or survival with severe sequelae (aOR, 1.3; 95% CI, 0.4-4.0) versus survival without severe sequelae. Patient interval was shorter in younger children (adjusted hazard ratio [aHR], 0.95; 95% CI, 0.92-0.99), and medical interval was reduced when the first consultation was conducted in a hospital (aHR, 1.5; 95% CI, 1.1-2.0) versus outpatient medicine. CONCLUSIONS: For children with COSBI, we found no significant association between medical interval and mortality or severe sequelae. An initial hospital referral could help reduce the time to antibiotics in COSBIs.

AIM: To investigate the prevalence of infections by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other respiratory viruses among children admitted to paediatric emergency departments (PEDs). METHODS: From April to July 2020, a prospective, multicentre cohort study was conducted in the PEDs of eight French university hospitals. Regardless of the reason for admission, a nasopharyngeal swab sample from each child was screened using reverse transcription polymerase chain reaction tests for SARS-CoV-2 and other respiratory viruses. We determined the prevalence of SARS-CoV-2 and other respiratory viruses and identified risk factors associated with a positive test. RESULTS: Of the 924 included children (median [interquartile range] age: 4 years [1-9]; boys: 55%), 908 (98.3%) were tested for SARS-CoV-2. Only three samples were positive (0.3%; 95% confidence interval: 0.1-1) and none of these children had symptoms of coronavirus disease 2019. Of the 836 samples (90%) tested for other viruses, 129 (15.4%) were positive (primarily rhinovirus). Respiratory viruses were significantly more common in young children and in children with respiratory tract symptoms and fever. CONCLUSION: The prevalence of SARS-CoV-2 among children admitted to emergency departments was low. In contrast, and despite social distancing and other protective measures, the prevalence of other respiratory viruses detection was high.

OBJECTIVES: To describe the epidemiology of community-onset severe bacterial infections in children and its recent evolution. DESIGN: Prospective, observational, population-based study from 2009 to 2014. SETTING: An administrative area accounting for 13% of the French pediatric population. PATIENTS: All children 1 month to 16 years old who died before admission or were admitted to a PICU for a community-onset severe bacterial infection. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The incidence and mortality rate of community-onset severe bacterial infections were compared with data from a reference population-based study conducted between 2000 and 2006, that is, before national recommendations for antimeningococcal C and antipneumococcal generalized vaccinations. Among the 261 children included (median age 25 mo), 28 (10.7%) died. The main diagnoses were meningitis (n = 85; 32%) and purpura fulminans (n = 59; 22%). The most common isolated bacteria were Neisseria meningitidis (n = 75; 29%), including 47 (63%) cases of serogroup B and 15 (20%) serogroup C, Streptococcus pneumoniae (n = 49, 19%), and Staphylococcus aureus (n = 15; 6%). The incidence of community-onset severe bacterial infections was three per 100,000 person-years (95% CI, 2.6-3.3) and had decreased by 53% from the reference period. Mortality rate was 0.3 per 100,000 person-years (95% CI, 0.2-0.4) and had decreased by 73% from the reference period. The incidence of community-onset severe bacterial infections caused by N. meningitidis and S. pneumoniae was 0.8 and 0.5 per 100,000 person-years and had decreased by 70% and 67% from the reference period. The incidence of community-onset severe bacterial infections-related to Staphylococcus aureus was 0.16 per 100,000 person-years and had increased by 220% from the reference period. CONCLUSIONS: The incidence and mortality rate of community-onset severe bacterial infections, except for S. aureus infection, have decreased in France. N. meningitidis and S. pneumoniae continue to account for many infections, which indicates the need for better vaccination coverage and spectrum.

AIM: Our objectives were to measure the vaccine coverage rates for children with chronic diseases as well as the prevalence of potentially harmful delays for generally recommended vaccines. We also identified the factors influencing non-adherence to vaccines specifically recommended for chronic conditions. METHODS: Three non-interventional point-prevalence surveys were performed in 2014 in all paediatric units at Lille University Hospital among children aged 2 months-18 years with chronic diseases and vaccination data. Vaccine coverage and delays for generally recommended vaccines were studied. The children who were up-to-date and those under-vaccinated for specifically indicated vaccines were compared and the factors potentially associated with under-vaccination were studied with multivariable analysis. RESULTS: We screened 682 patients: of 207 with chronic diseases, mainly neurological, muscular and respiratory disorders, 146 had vaccination data. Only 47% (95% confidence interval 39-55) were up-to-date for all generally recommended vaccinations; potentially harmful vaccination delays were high (26%-75%). Only 11% of the 81% of patients for whom some vaccines were specifically recommended were up-to-date. Low maternal education level was significantly associated with under-vaccination (adjusted odds ratio 10.5, 95% confidence interval 1.3-86.9, P = .03). CONCLUSION: This study showed inadequate vaccine coverage rates and significant delays among children with chronic diseases.

BACKGROUND: In a context of suboptimal vaccination coverage and increasing vaccine hesitancy, we aimed to study morbidity and mortality in children related to missing or incomplete meningococcal C and pneumococcal conjugate vaccines. METHODS: We conducted a prospective, observational, population-based study from 2009 to 2014 in a French administrative area that included all children from age 1 month to 16 years who died before admission or were admitted to an intensive care unit for a community-onset bacterial infection. Vaccine-preventable infection was defined as an infection with an identified serotype included in the national vaccine schedule at the time of infection and occurring in a non- or incompletely vaccinated child. Death and severe sequelae were studied at hospital discharge. Frequencies of vaccine-preventable morbidity and mortality caused by meningococcus and pneumococcus were calculated. RESULTS: Among the 124 children with serotyped meningococcal (n = 75) or pneumococcal (n = 49) severe infections included (median age 26 months), 20 (16%) died and 12 (10%) had severe sequelae. Vaccine-preventable infections accounted for 18/124 infections (15%, 95% CI 9, 22), 5/20 deaths (25%, 95% CI 9, 49), and 3/12 severe sequelae cases (25%, 95% CI 0, 54). The vaccine schedule for meningococcal C and pneumococcal conjugate vaccinations was incomplete for 71/116 (61%) children targeted by at least one of these two vaccination programs. CONCLUSIONS: Mortality and morbidity rates related to vaccine-preventable meningococcal or pneumococcal infection could be reduced by one quarter with better implementation of immunisation programs. Such information could help enhance the perception of vaccine benefits and fight vaccine hesitancy.

BACKGROUND: In 2012, new international guidelines for children with chemotherapy-induced febrile neutropenia (FN) were issued, recommending reduced-intensity management strategy based on stratification of infectious risks. Some studies have highlighted practice disparities in different countries and within the same country. Our aim was to assess the current management strategies for the treatment of chemotherapy-induced FN in children in France. PROCEDURE: This survey of all French pediatric oncology-hematology reference centers (n = 30) in late 2012 and early 2013 sent a standardized questionnaire to each center inquiring about their definition of an FN episode, its initial empiric treatment and ongoing management, use of management stratified by risk, and any criteria used for the risk assessment. Each center's management protocol was also analyzed. RESULTS: All French reference centers participated in this survey, completing 88% of the questionnaire items. Definitions of both fever and neutropenia varied between centers. Ten centers used a risk-stratification strategy for initial management. In all, 42 probabilistic first-line antibiotic treatments were identified. After 48 hr of apyrexia, 17 units applied different forms of step-down therapy. CONCLUSIONS: Most French centers already offered some form of reduced-intensity or step-down therapy, although they differed substantially in their management of FN episodes. Risk stratification with validated tools is essential to facilitate the implementation of the international recommendations, which would ultimately help to standardize practices in France.

Health organizations are complex to manage due to their dynamic processes and distributed hospital organization. It is therefore necessary for healthcare institutions to focus on this issue to deal with patients' requirements. We aim in this paper to develop and implement a management decision support system (DSS) that can help physicians to better manage their organization and anticipate the feature of overcrowding. Our objective is to optimize the Pediatric Emergency Department (PED) functioning characterized by stochastic arrivals of patients leading to its services overload. Human resources allocation presents additional complexity related to their different levels of skills and uncertain availability dates. So, we propose a new approach for multi-healthcare task scheduling based on a dynamic multi-agent system. Decisions about assignment and scheduling are the result of a cooperation and negotiation between agents with different behaviors. We therefore define the actors involved in the agents' coalition to manage uncertainties related to the scheduling problem and we detail their behaviors. Agents have the same goal, which is to enhance care quality and minimize long waiting times while respecting degrees of emergency. Different visits to the PED services and regular meetings with the medical staff allowed us to model the PED architecture and identify the characteristics and different roles of the healthcare providers and the diverse aspects of the PED activities. Our approach is integrated in a DSS for the management of the Regional University Hospital Center (RUHC) of Lille (France). Our survey is included in the French National Research Agency (ANR) project HOST (Hôpital: Optimisation, Simulation et évitement des Tensions (ANR-11-TecSan-010: http://host.ec-lille.fr/wp-content/themes/twentyeleven/docsANR/R0/HOST-WP0.pdf)).

BACKGROUND: Lower respiratory tract infection is a common cause of consultation and antibiotic prescription in paediatric practice. The misuse of antibiotics is a major cause of the emergence of multidrug-resistant bacteria. The aim of this study was to evaluate the frequency, changes over time, and determinants of non-compliance with antibiotic prescription recommendations for children admitted in paediatric emergency department (PED) with community-acquired pneumonia (CAP). METHODS: We conducted a prospective two-period study using data from the French pneumonia network that included all children with CAP, aged one month to 15 years old, admitted to one of the ten participating paediatric emergency departments. In the first period, data from children included in all ten centres were analysed. In the second period, we analysed children in three centers for which we collected additional data. Two experts assessed compliance with the current French recommendations. Independent determinants of non-compliance were evaluated using a logistic regression model. The frequency of non-compliance was compared between the two periods for the same centres in univariate analysis, after adjustment for confounding factors. RESULTS: A total of 3034 children were included during the first period (from May 2009 to May 2011) and 293 in the second period (from January to July 2012). Median ages were 3.0 years [1.4-5] in the first period and 3.6 years in the second period. The main reasons for non-compliance were the improper use of broad-spectrum antibiotics or combinations of antibiotics. Factors that were independently associated with non-compliance with recommendations were younger age, presence of risk factors for pneumococcal infection, and hospitalization. We also observed significant differences in compliance between the treatment centres during the first period. The frequency of non-compliance significantly decreased from 48 to 18.8 % between 2009 and 2012. The association between period and non-compliance remained statistically significant after adjustment for confounding factors. Amoxicillin was prescribed as the sole therapy significantly more frequently in the second period (71 % vs. 54.2 %, p < 0.001). CONCLUSIONS: We observed a significant increase in the compliance with recommendations, with a reduction in the prescription of broad-spectrum antibiotics, efforts to improve antibiotic prescriptions must continue.

The workflow models of the patient journey in a Pediatric Emergency Department (PED) seems to be an effective approach to develop an accurate and complete representation of the PED processes. This model can drive the collection of comprehensive quantitative and qualitative service delivery and patient treatment data as an evidence base for the PED service planning. Our objective in this study is to identify crowded situation indicators and bottlenecks that contribute to over-crowding. The greatest source of delay in patient flow is the waiting time from the health care request, and especially the bed request to exit from the PED for hospital admission. It represented 70% of the time that these patients occupied in the PED waiting rooms. The use of real data to construct the workflow model of the patient path is effective in identifying sources of delay in patient flow, and aspects of the PED activity that could be improved. The development of this model was based on accurate visits made in the PED of the Regional University Hospital Center (CHRU) of Lille (France). This modeling, which has to represent most faithfully possible the reality of the PED of CHRU of Lille, is necessary. It must be detailed enough to produce an analysis allowing to identify the dysfunctions of the PED and also to propose and to estimate prevention indicators of crowded situations. Our survey is integrated into the French National Research Agency (ANR) project, titled: "Hospital: Optimization, Simulation and avoidance of strain" (HOST).

To distinguish children with chemotherapy-induced febrile neutropenia (FN) at low risk of severe infection, the variables that are significant risk factors must be identified. Our objective was to identify them by applying evidence-based standards. This retrospective 2-center cohort study included all episodes of chemotherapy-induced FN in children in 2005 and 2006. The medical history, clinical, and laboratory data available at admission were collected. Severe infection was defined by bacteremia, a positive culture of a normally sterile body fluid, invasive fungal infection, or localized infection at high risk of extension. Univariate analysis identified potential predictive variables. A generalized mixed model was used to determine the adjusted variables that predict severe infection. We analyzed 372 FN episodes. Severe infections occurred in 16.1% of them. Variables predictive of severe infection at admission were: disease with high risk of prolonged neutropenia (adjusted odds ratio [aOR]=2.5), blood cancer (aOR=1.9), fever ≥38.5°C (aOR=3.7), and C-reactive protein level ≥90 mg/L (aOR=4.5). Now that we have identified these variables significantly associated with the risk of severe infection, they must be validated prospectively before combining the best predictive variables in a decision rule that can be used to distinguish children at low risk.

BACKGROUND: Clinical decision rules (CDRs) have sought to identify the few children with chemotherapy-induced febrile neutropenia (FN) really at risk of severe infection to reduce the invasive procedures and costs for those at low risk. Several reports have shown that most rules do not perform well enough to be clinically useful. Our objective was to analyze the derivation methods and validation procedures of these CDRs. PROCEDURE: A systematic review using Medline, Ovid, Refdoc, and the Cochrane Library through December 2012 searched for all CDRs predicting the risk of severe infection and/or complications in children with chemotherapy-induced FN. Their methodological quality was analyzed by 17 criteria for deriving and validating a CDR identified in the literature. The criteria published by the Evidence Based Medicine Working Group were applied to the published validations of each CDR to assess their level of evidence. RESULTS: The systematic research identified 612 articles and retained 12 that derived CDRs. Overall, the CDRs met a median of 65% of the methodological criteria. The criteria met least often were that the rule made clinical sense, or described the course of action, or that the variables and the CDR were reproducible. Only one CDR, developed in South America, met all methodological criteria and provided the highest level of evidence; unfortunately it was not reproducible in Europe. CONCLUSION: Only one CDR developed for children with FN met all methodological standards and reached the highest level of evidence.

BACKGROUND AND PURPOSE: Plain radiographs may fail to reveal an ankle fracture in children because of developmental and anatomical characteristics. In this systematic review and meta- analysis, we estimated the prevalence of occult fractures in children with acute ankle injuries and clinical suspicion of fracture, and assessed the diagnostic accuracy of ultrasound (US) in the detection of occult fractures. METHODS: We searched the literature and included studies reporting the prevalence of occult fractures in children with acute ankle injuries and clinical suspicion of fracture. Proportion meta-analysis was performed to calculate the pooled prevalence of occult fractures. For each individual study exploring the US diagnostic accuracy, we calculated US operating characteristics. RESULTS: 9 studies (involving 187 patients) using magnetic resonance imaging (MRI) (n = 5) or late radiographs (n = 4) as reference standard were included, 2 of which also assessed the diagnostic accuracy of US. Out of the 187 children, 41 were found to have an occult fracture. The pooled prevalence of occult fractures was 24% (95% CI: 18-31). The operating characteristics for detection of occult ankle fractures by US ranged in positive likelihood ratio (LR) from 9 to 20, and in negative LR from 0.04 to 0.08. INTERPRETATION: A substantial proportion of fractures may be overlooked on plain radiographs in children with acute ankle injuries and clinical suspicion of fracture. US appears to be a promising method for detection of ankle fractures in such children when plain radiographs are negative.

BACKGROUND: The continual increase in patient attendance at the emergency department (ED) is a worldwide health issue. The aim of this study was to determine whether the use of a secondary prioritization software reduces the patients' median length of stay (LOS) in the pediatric ED. METHODS: A randomized, controlled, open-label trial was conducted over a 30-day period between March 15th and April 23rd 2021 at Lille University Hospital. Work days were randomized to use the patient prioritization software or the pediatric ED's standard dashboard. All time intervals between admission and discharge were recorded prospectively by a physician not involved in patient care during the study period. The study's primary endpoint was the LOS in the pediatric ED, which was expected to be 15 min shorter in the intervention group than in the control group. The secondary endpoints were specific time intervals during the stay in the pediatric ED and levels of staff satisfaction. RESULTS: 1599 patients were included: 798 in the intervention group and 801 in the control group. The median [interquartile range] LOS was 172 min [113-255] in the intervention group and 167 min [108-254) in the control group (p = 0.46). In the intervention group, the time interval between admission to the first medical evaluation for high-priority patients and the time interval between the senior physician's final evaluation and patient discharge were shorter (p < 0.01). The median satisfaction score was 68 [55-80] (average). CONCLUSION: The patients' total LOS was not significantly shorter on days of intervention. However, use of the electronic patient prioritization tool was associated with significant decreases in some important time intervals during care in the pediatric ED.

RESUMEN
PURPOSE OF REVIEW: Chemotherapy-induced febrile neutropenia is a frequent event in children with cancer with possible severe complications. However, increasing evidence indicates that early discharge or outpatient therapy can safely be proposed for children with low-risk febrile neutropenia. Clinical decision rules (CDRs) have been proposed to help predict the risk of severe infection in children with chemotherapy-induced febrile neutropenia, but none has been fully validated. RECENT FINDINGS: The aim of CDRs for children with febrile neutropenia would be to identify patients at low risk of severe infection. At least 16 different CDRs have been proposed. Only a few have been tested across multiple datasets. Some CDRs were reproducible, but none fulfilled the requirements for validation. Different definitions of outcome and the lack of rigorous methods for derivation probably explain why no validated CDR yet exists for children with febrile neutropenia. SUMMARY: A consensus definition of the best outcome in clinical practice is essential. It must then be followed by multiple and large-scale validations of a CDR that meets all methodological criteria, with high sensitivity and enough specificity to enable physicians to safely propose an outpatient management strategy for patients identified as at low risk of severe complications related to febrile neutropenia.

Delayed diagnosis of paediatric cancers is reported regularly and is a source of remorse for physicians and parents and a leading cause of malpractice claims. We did a systematic review of information about the distribution, determinants, and consequences of time to diagnosis of paediatric malignancies and compared these findings with those of court-appointed expert witnesses in malpractice claims in Canada and France. Time to diagnosis varied widely between tumour types in the 98 relevant studies (medians ranged from 2-260 weeks) without any significant decrease with time. Determinants of a long delay in diagnosis included older age, qualification of the first physician contacted, non-specific symptoms, histological type, and tumour localisation. Delayed diagnosis was associated with poor outcome for retinoblastoma and possibly for leukaemia, nephroblastoma, and rhabdomyosarcoma (data were insufficient for definitive conclusions). It was not associated with an adverse outcome for most CNS tumours, osteosarcoma or Ewing's sarcoma, and, paradoxically, was frequently associated with better outcomes than was short time to diagnosis in these cancers. A third of the court-appointed experts provided testimony concordant with the medical literature. The relations between delay in diagnosis and outcome are complex and probably depend more on tumour biology than on parental or medical factors.

AIM: Various diagnostic criteria have been proposed for bone or joint infection. This study used a Delphi process to determine the consensual definitions for arthritis, osteomyelitis and bone or joint infections in general in children. METHODS: A group of European French-speaking experts participated in an email Delphi process. Definitions were identified during a systematic search of the PubMed database. Five definitions of arthritis, eight for osteomyelitis and five for bone or joint infections in general were included in a three-round process. We sought two sorts of definitions: definitions for 'definitive' diagnoses for epidemiological studies and definitions for 'probable' diagnoses for clinical or therapeutic studies, considering enlarged criteria. RESULTS: Ten experts were involved in the Delphi process. A consensus was reached for a definitive diagnosis of arthritis, osteomyelitis and bone or joint infections in general. A consensus was also reached for a probable diagnosis of bone or joint infections in general. CONCLUSION: This Delphi process made consensus definitions and criteria available for bone or joint infections that could improve the comparability of both epidemiological and clinical studies. This is a first step to standardise diagnostic criteria and distinguish definitive and probable bone or joint infections in children.

BACKGROUND: Although influenza viruses cause significant morbidity and mortality worldwide, the impact of these infections on children in France and in other European countries has not been extensively characterized. The primary objective of the present study was to describe the burden of influenza disease on hospitalized children under 2 years of age in France, using data from the national hospital discharge summary database (Programme de Médicalisation des Systèmes d'Information, PMSI). METHODS: In a retrospective study of hospital admissions for influenza among children under the age of 2 in France, we extracted and analyzed hospital administrative data from the PMSI database (from January 1, 2011, to December 31, 2020). RESULTS: From 2011 to 2020, 28,507 children under the age of 2 were admitted to hospital with a primary or secondary diagnosis of influenza infection. The hospital admission rate was 205 per 100,000 for children under the age of 2, 276 per 100,000 for children under the age of 12 months, and 135 per 100,000 for children aged between 12 and 23 months. Children under 6 months of age were the most affected (45.4%). An underlying condition was identified for 9.4% of the children, and 2.2% of the children were admitted to the intensive care unit. The death rate was 0.12 per 100,000 for children under 2, 0.11 per 100,000 for children under 12 months, and 0.16 per 100,000 for children aged between 12 and 23 months. CONCLUSIONS: In France, the burden of influenza disease is significant in children under the age of 2.

Importance: Assessment of the quality of initial care is necessary to target priority actions that can reduce the still high morbidity and mortality due to community-onset severe bacterial infections (COSBIs) among children. Objective: To study the prevalence, characteristics, and determinants of suboptimal care in the initial management of COSBIs. Design, Setting, and Participants: This prospective, population-based, cohort study and confidential enquiry was conducted between August 2009 and January 2014 in western France, a region accounting for 15% of the French pediatric population (1â¯968â¯474 children aged 1 month to 16 years) and including 6 pediatric intensive care units (PICUs) and 35 emergency departments. Participants included all children aged 1 month to 16 years who died before PICU admission or were admitted to a PICU with a COSBI (ie, bacterial sepsis, including meningitis, purpura fulminans, and pulmonary, osteoarticular, intra-abdominal, cardiac, and soft-tissue severe infections). Data were analyzed from March to June 2020. Exposures: Suboptimal care determined according to evaluation of 8 types of care: (1) the delay in seeking care by family, (2) the physician's evaluation of severity, (3) the patient's referral at the first consultation with signs of severity, (4) the timing and (5) dosage of antibiotic treatment, (6) the timing and (7) volume of fluid bolus administration, and (8) the clinical reassessment after fluid bolus. Main Outcomes and Measures: Two experts assessed the quality of care before death or PICU admission as optimal, possibly suboptimal, or certainly suboptimal. The consequences and determinants of certainly suboptimal care were identified with multinomial logistic regression and generalized linear mixed models. Results: Of the 259 children included (median [IQR] age, 24 [6-66] months; 143 boys [55.2%]), 27 (10.4%) died, and 25 (9.6%) had severe sequelae at PICU discharge. The quality of care was certainly suboptimal in 89 cases (34.4%). Suboptimal care was more frequent in children with sequelae (adjusted odds ratio [aOR], 5.61; 95% CI, 1.19-26.36) and less frequent in children who died (aOR, 0.16; 95% CI, 0.04-0.65) vs those surviving without sequelae. Factors independently associated with suboptimal care were age younger than 5 years (aOR, 3.15; 95% CI, 1.25-7.90), diagnosis of sepsis with no source (aOR, 5.77; 95% CI, 1.64-20.30) or meningitis (aOR, 3.39; 95% CI, 1.15-9.96) vs other severe infections, and care by a primary care physician (aOR, 3.22; 95% CI, 1.17-8.88) vs a pediatric hospital service. Conclusions and Relevance: This study found that suboptimal care is frequent in the initial management of COSBI and is associated with severe sequelae. The paradoxical association with reduced risk of death may be explained by an insufficient adjustment on bacterial or host intrinsic factors. Management could be optimized by improving the quality of primary care, especially for young children.

BACKGROUND: In 2017, international guidelines proposed new management of febrile neutropenia in children with cancer, adapted to the risk of severe infection by clinical decision rules (CDRs). Until now, none of the proposed CDRs has performed well enough in high-income countries for use in clinical practice. Our study aimed to build and validate a new CDR (DISCERN-FN) to predict the risk of severe infection in children with febrile neutropenia. METHODS: We did two prospective studies. First, a prospective derivation study included all episodes of febrile neutropenia in children (aged <18 years) with a cancer diagnosis and receiving treatment for it who were admitted for an episode of febrile neutropenia, excluding patients already treated with antibiotics for this episode, febrile neutropenia not induced by chemotherapy, those receiving palliative care, and those with a stem cell allograft for less than 1 year, from April 1, 2007, to Dec 31, 2011 from two paediatric cancer centres in France. We collected the children's medical history, and clinical and laboratory data, and analysed their associations with severe infection. Sipina software was used to derive the CDR as a decision tree. Second, a prospective, national, external validation study was done in 23 centres from Jan 1, 2012, to May 31, 2016. The primary outcome was severe infection, defined by bacteraemia, a positive bacterial culture from a usually sterile site, a local infection with a high potential for extension, or an invasive fungal infection. The CDR was applied a posteriori to all episodes to evaluate its sensitivity, specificity, and negative likelihood ratio. FINDINGS: The derivation set included 539 febrile neutropenia episodes (270 episodes in patients with blood cancer [median age 7·5 years, IQR 3·7-11·2; 158 (59 %) boys and 112 (41%) girls] and 269 in patients with solid tumours [median age 6·6 years, IQR 2·9-14·2; 140 (52 %) boys and 129 (48%) girls]). Significant variables introduced into the decision tree were cancer type (solid tumour vs blood cancer), age, high-risk chemotherapy, level of fever, C-reactive protein concentration (at 24-48 h after admission), and leucocyte and platelet counts and procalcitonin (at admission and at 24-48 h after admission). For the derivation set, the CDR sensitivity was 98% (95% CI 93-100), its specificity 56% (51-61), and the negative likelihood ratio 0·04 (0·01-0·15). 1806 febrile neutropenia episodes were analysed in the validation set (mean age 8·1 years [SD 4·8], 1014 (56%) boys and 792 (44%) girls), of which 332 (18%, 95% CI 17-20) were linked with severe infection. For the validation set, the CDR had a sensitivity of 95% (95% CI 91-97), a specificity of 38% (36-41), and a negative likelihood ratio of 0·13 (0·08-0·21). Our CDR reduced the risk of severe infection to a post-test probability of 0·8% (95% CI 0·2-2·9) in the derivation set and 2·4% (1·5-3·9) in the validation set. The validation study is registered at ClinicalTrials.gov, NCT03434795. INTERPRETATION: The use of our CDR substantially reduced the risk of severe infection after testing in both the derivation and validation groups, which suggests that this CDR would improve clinical practice enough to be introduced in appropriate settings.
