Background: The timing and necessity of repeated blood cultures (BCs) in children with cancer and febrile neutropenia (FN) are unknown. We evaluated the diagnostic yield of BCs collected pre- and post-empiric FN antibiotics. Method(s): Data collected prospectively from the Australian Predicting Infectious ComplicatioNs in Children with Cancer (PICNICC) study were used. Diagnostic yield was calculated as the number of FN episodes with a true bloodstream infection (BSI) detected divided by the number of FN episodes that had a BC taken. Result(s): A BSI was identified in 13% of 858 FN episodes. The diagnostic yield of pre-antibiotic BCs was higher than of post-antibiotic cultures (12.3% vs 4.4%, P <. 001). Two-thirds of the post-antibiotic BSIs were associated with a new episode of fever or clinical instability, and only 2 new BSIs were identified after 48 hours of empiric antibiotics and persistent fever. A contaminated BC was identified more frequently in post-antibiotic cultures. Conclusion(s): In the absence of new fever or clinical instability, BCs beyond 48 hours of persistent fever have limited yield. Opportunity exists to optimize BC collection in this population and reduce the burden of unnecessary tests on patients, healthcare workers, and hospitals.Copyright © 2020 The Author(s) 2020.

Introduction: A pandemic coronavirus, SARS-CoV-2, causes COVID-19, a potentially life-threatening respiratory disease. Patients with cancer may have compromised immunity due to their malignancy and/or treatment, and may be at elevated risk of severe COVID-19. Community transmission of COVID-19 could overwhelm health care services, compromising delivery of cancer care. This interim consensus guidance provides advice for clinicians managing patients with cancer during the pandemic. Main recommendations: During the COVID-19 pandemic:. In patients with cancer with fever and/or respiratory symptoms, consider causes in addition to COVID-19, including other infections and therapy-related pneumonitis. For suspected or confirmed COVID-19, discuss temporary cessation of cancer therapy with a relevant specialist. Provide information on COVID-19 for patients and carers. Adopt measures within cancer centres to reduce risk of nosocomial SARS-CoV-2 acquisition; support population-wide social distancing; reduce demand on acute services; ensure adequate staffing; and provide culturally safe care. Measures should be equitable, transparent and proportionate to the COVID-19 threat. Consider the risks and benefits of modifying cancer therapies due to COVID-19. Communicate treatment modifications, and review once health service capacity allows. Consider potential impacts of COVID-19 on the blood supply and availability of stem cell donors. Discuss and document goals of care, and involve palliative care services in contingency planning. Changes in management as a result of this statement: This interim consensus guidance provides a framework for clinicians managing patients with cancer during the COVID-19 pandemic. In view of the rapidly changing situation, clinicians must also monitor national, state, local and institutional policies, which will take precedence.

Background: A thorough understanding of local and contemporary invasive fungal infection (IFI) epidemiology in immunocompromised children is required to provide a rationale for targeted prevention and treatment strategies. Method(s): Retrospective data over 10 years from four tertiary pediatric oncology and hematopoietic stem cell transplant (HSCT) units across Australia were analyzed to report demographic, clinical, and mycological characteristics of IFI episodes, and crude IFI prevalence in select oncology/HSCT groups. Kaplan-Meier survival analyses were used to calculate 180-day overall survival. Result(s): A total of 337 IFI episodes occurred in 320 children, of which 149 (44.2%), 51 (15.1%), and 110 (32.6%) met a modified European Organization for Research and Treatment of Cancer (mEORTC) criteria for proven, probable, and possible IFI, respectively. There were a further 27 (8.0%) that met a "modified possible IFI" criteria. Median age at IFI diagnosis was 8.4 years. Crude mEORTC IFI prevalence in acute lymphoblastic leukemia, acute myeloid leukemia, solid tumor, and allogeneic HSCT cohorts was 10.6%, 28.2%, 4.4%, and 11.7%, respectively. Non-Aspergillus species represented 48/102 (47.1%) molds identified, and non-albicans Candida represented 66/93 (71.0%) yeasts identified. There were 56 deaths among 297 children who met mEORTC criteria, with 180-day overall survival for proven, probable, and possible IFIs of 79.7%, 76.2%, and 84.4%, respectively. Conclusion(s): Non-Aspergillus molds and non-albicans Candida contributed substantially to pediatric IFI in our study, with high IFI prevalence in leukemia and allogeneic HSCT cohorts. Inclusion of IFIs outside of European Organization for Research and Treatment of Cancer criteria revealed an IFI burden that would go otherwise unrecognized in published reports.Copyright © 2018 Wiley Periodicals, Inc.

Background: Fever and neutropenia (FN) clinical decision rules (CDRs) are recommended to help distinguish children with cancer at high and low risk of severe infection. The aim of this study was to validate existing pediatric FN CDRs designed to stratify children with cancer at high or low risk of serious infection or medical complication. Method(s): Pediatric CDRs suitable for validation were identified from a literature search. Relevant data were extracted from an existing data set of 650 retrospective FN episodes in children with cancer. The sensitivity and specificity of each of the CDR were compared with the derivation studies to assess reproducibility. Result(s): Six CDRs were identified for validation: 2 were designed to predict bacteremia and 4 to predict adverse events. Five CDRs exhibited reproducibility in our cohort. A rule predicting bacteremia had the highest sensitivity (100%; 95% confidence interval (CI): 93%-100%) although poor specificity (17%), with only 15% identified as low risk. For adverse events, the highest sensitivity achieved was 84% (95% CI: 75%-90%), with specificity of 29% and 27% identified as low risk. A rule intended for application after a 24-hour period of inpatient observation yielded a sensitivity of 80% (95% CI: 73-86) and specificity of 46%, with 44% identified as low risk. Conclusion(s): Five CDRs were reproducible, although not all can be recommended for implementation because of either inadequate sensitivity or failure to identify a clinically meaningful number of low-risk patients. The 24-hour rule arguably exhibits the best balance between sensitivity and specificity in our population.Copyright © 2017 Wolters Kluwer Health, Inc. All rights reserved.

Aim: Variation in the management of fever and neutropenia (FN) in children is well described. The aim of this study was to explore the current management of FN across Australia and New Zealand and highlight areas for improvement. Method(s): A practice survey was administered to paediatric health-care providers via four clinical and research networks. Using three clinical case vignettes, we explored risk stratification, empiric antibiotics, initial investigations, intravenous-oral switch, ambulatory management and antibiotic duration in children with cancer and FN. Result(s): A response was received from 104 participants from 16 different hospitals. FN guideline compliance was rated as moderate or poor by 24% of respondents, and seven different fever definitions were described. There was little variation in the selected empiric monotherapy and dual-therapy regimens, and almost all respondents recommended first-dose antibiotics within 1 h. However, 27 different empiric antibiotic combinations were selected for beta-lactam allergy. An incorrect risk status was assigned to the low-risk case by 27% of respondents and to the high-risk case by 41%. Compared to current practice, significantly more respondents would manage the low-risk case in the ambulatory setting provided adequate resources were in place (43 vs. 85%, P < 0.0001). There was variation in the use of empiric glycopeptides as well as use of aminoglycosides beyond 48 h. Conclusion(s): Although the antibiotics selected for empiric management of FN are appropriate and consistent, variation and inaccuracies exist in risk stratification, the selection of monotherapy over dual therapy, empiric antibiotics chosen for beta-lactam allergy, use of glycopeptides and duration of aminoglycosides.Copyright © 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians)

Purpose: To update a clinical practice guideline (CPG) for the empirical management of fever and neutropenia (FN) in children with cancer and hematopoietic stem-cell transplantation recipients. Method(s): The International Pediatric Fever and Neutropenia Guideline Panel is a multidisciplinary and multinational group of experts in pediatric oncology and infectious diseases that includes a patient advocate. For questions of risk stratification and evaluation, we updated systematic reviews of observational studies. For questions of therapy, we conducted a systematic review of randomized trials of any intervention applied for the empirical management of pediatric FN. The Grading of Recommendation Assessment, Development and Evaluation approach was used to make strong or weak recommendations and to classify levels of evidence as high, moderate, low, or very low. Result(s): Recommendations related to initial presentation, ongoing management, and empirical antifungal therapy of pediatric FN were reviewed; the most substantial changes were related to empirical antifungal therapy. Key differences from our 2012 FN CPG included the listing of a fourth-generation cephalosporin for empirical therapy in high-risk FN, refinement of risk stratification to define patients with high-risk invasive fungal disease (IFD), changes in recommended biomarkers and radiologic investigations for the evaluation of IFD in prolonged FN, and a weak recommendation to withhold empirical antifungal therapy in IFD low-risk patients with prolonged FN. Conclusion(s): Changes to the updated FN CPG recommendations will likely influence the care of pediatric patients with cancer and those undergoing hematopoietic stem-cell transplantation. Future work should focus on closing research gaps and on identifying ways to facilitate implementation and adaptation.Copyright © 2017 by American Society of Clinical Oncology.

Background:The aim of this study was to validate the 'Predicting Infectious ComplicatioNs in Children with Cancer' (PICNICC) clinical decision rule (CDR) that predicts microbiologically documented infection (MDI) in children with cancer and fever and neutropenia (FN). We also investigated costs associated with current FN management strategies in Australia. Method(s):Demographic, episode, outcome and cost data were retrospectively collected on 650 episodes of FN. We assessed the discrimination, calibration, sensitivity and specificity of the PICNICC CDR in our cohort compared with the derivation data set. Result(s):Using the original variable coefficients, the CDR performed poorly. After recalibration the PICNICC CDR had an area under the receiver operating characteristic (AUC-ROC) curve of 0.638 (95% CI 0.590-0.685) and calibration slope of 0.24. The sensitivity, specificity, positive predictive value and negative predictive value of the PICNICC CDR at presentation was 78.4%, 39.8%, 28.6% and 85.7%, respectively. For bacteraemia, the sensitivity improved to 85.2% and AUC-ROC to 0.71. Application at day 2, taking into consideration the proportion of MDI known (43%), further improved the sensitivity to 87.7%. Length of stay is the main contributor to cost of FN treatment, with an average cost per day of AUD 2183 in the low-risk group. Conclusion(s):For prediction of any MDI, the PICNICC rule did not perform as well at presentation in our cohort as compared with the derivation study. However, for bacteraemia, the predictive ability was similar to that of the derivation study, highlighting the importance of recalibration using local data. Performance also improved after an overnight period of observation. Implementation of a low-risk pathway, using the PICNICC CDR after a short period of inpatient observation, is likely to be safe and has the potential to reduce health-care expenditure.Copyright © 2017 Cancer Research UK.

Background:Risk-stratified management of fever with neutropenia (FN), allows intensive management of high-risk cases and early discharge of low-risk cases. No single, internationally validated, prediction model of the risk of adverse outcomes exists for children and young people. An individual patient data (IPD) meta-analysis was undertaken to devise one. Method(s):The 'Predicting Infectious Complications in Children with Cancer' (PICNICC) collaboration was formed by parent representatives, international clinical and methodological experts. Univariable and multivariable analyses, using random effects logistic regression, were undertaken to derive and internally validate a risk-prediction model for outcomes of episodes of FN based on clinical and laboratory data at presentation. Result(s):Data came from 22 different study groups from 15 countries, of 5127 episodes of FN in 3504 patients. There were 1070 episodes in 616 patients from seven studies available for multivariable analysis. Univariable analyses showed associations with microbiologically defined infection (MDI) in many items, including higher temperature, lower white cell counts and acute myeloid leukaemia, but not age. Patients with osteosarcoma/Ewings sarcoma and those with more severe mucositis were associated with a decreased risk of MDI. The predictive model included: malignancy type, temperature, clinically 'severely unwell', haemoglobin, white cell count and absolute monocyte count. It showed moderate discrimination (AUROC 0.723, 95% confidence interval 0.711-0.759) and good calibration (calibration slope 0.95). The model was robust to bootstrap and cross-validation sensitivity analyses. Conclusion(s):This new prediction model for risk of MDI appears accurate. It requires prospective studies assessing implementation to assist clinicians and parents/patients in individualised decision making.Copyright © 2016 Cancer Research UK.

Few studies are available to inform duration of intravenous antibiotics for children and when it is safe and appropriate to switch to oral antibiotics. We have systematically reviewed antibiotic duration and timing of intravenous to oral switch for 36 paediatric infectious diseases and developed evidence-graded recommendations on the basis of the review, guidelines, and expert consensus. We searched databases and obtained information from references identified and relevant guidelines. All eligible studies were assessed for quality. 4090 articles were identified and 170 studies were included. Evidence relating antibiotic duration to outcomes in children for some infections was supported by meta-analyses or randomised controlled trials; in other infections data were from retrospective series only. Criteria for intravenous to oral switch commonly included defervescence and clinical improvement with or without improvement in laboratory markers. Evidence suggests that intravenous to oral switch can occur earlier than previously recommended for some infections. We have synthesised recommendations for antibiotic duration and intravenous to oral switch to support clinical decision making and prospective research.Copyright © 2016 Elsevier Ltd

Background: There are no specific recommendations for the design and reporting of studies of children with fever and neutropenia (FN). As a result, there is marked heterogeneity in the variables and outcomes that are reported and new definitions continue to emerge. These inconsistencies hinder the ability of researchers and clinicians to compare, contrast and combine results. The objective was to achieve expert consensus on a core set of variables and outcomes that should be measured and reported, as a minimum, in pediatric FN studies. Procedure: The Delphi method was used to achieve consensus among an international group of clinicians, pharmacists, researchers, and patient representatives. Four surveys focusing on (i) the identification of a core set of variables and outcomes; and (ii) definitions of these variables and outcomes, were administered electronically. Consensus was predefined as more than 80% agreement on any statement. Result(s): There were forty-five survey participants and the response rate ranged between 84 and 96%. There was consensus on eight core variables and 10 core outcomes that should be collected and reported in all studies of children with FN. Consensus definitions were identified for all of the core outcomes. Conclusion(s): Using the Delphi method, expert consensus on a set of core variables and outcomes, and their corresponding definitions, was achieved. These core sets represent the minimum that should be collected and reported in all studies of children with FN. This will promote collaboration and ensure consistency and comparability between studies.Copyright © 2014 Wiley Periodicals, Inc.

There is a strong argument for the use of antifungal prophylaxis in high-risk patients given the significant mortality associated with invasive fungal disease, the late identification of these infections, and the availability of safe and well-tolerated prophylactic medications. Clinical decisions about which patients should receive prophylaxis and choice of antifungal agent should be guided by risk stratification, knowledge of local fungal epidemiology, the efficacy and tolerability profile of available agents, and estimates such as number needed to treat and number needed to harm. There have been substantial changes in practice since the 2008 guidelines were published. These include the availability of new medications and/or formulations, and a focus on refining and simplifying patient risk stratification. Used in context, these guidelines aim to assist clinicians in providing optimal preventive care to this vulnerable patient demographic.Copyright © 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.

Risk stratification is recommended for children with cancer and fever and neutropenia. Further research is required to quantify the overall impact of this approach and to refine exactly which children will benefit from early antibiotic administration as well as modifications to empiric regimens to cover antibiotic-resistant organisms.Copyright © 2015 Wolters Kluwer Health, Inc.
