Characterization of gram-negative bloodstream infections in hospitalised Australian children and their clinical outcomes.

BACKGROUND: Gram-negative bloodstream infections (GNBSI) more commonly occur in children with comorbidities and are increasingly associated with antimicrobial resistance. There are few large studies of GNBSI in children that relate the clinical presentation, pathogen characteristics and outcomes. METHODS: A 3-year prospective study of GNBSI in children aged <18 years was conducted in five Australian children's hospitals between 2019-2021. The clinical characteristics, disease severity and outcomes were recorded. Causative pathogens underwent antibiotic susceptibility testing and whole genome sequencing. RESULTS: There were 931 GNBSI episodes involving 818 children. Median age was 3 years (IQR 0.6-8.5). 576/931 episodes (62%) were community onset though 661/931 (71%) occurred in children with comorbidities and a central venous catheter (CVC) was present in 558/931 (60%). CVC (145/931) and urinary tract (149/931) were the most common sources (16% each). 100/931 (11%) children required Intensive Care Unit (ICU) admission and a further 11% (105/931) developed GNBSI in ICU. 659/927 (71%) isolates were Enterobacterales of which 22% (138/630) were third generation cephalosporin resistant (3GCR). Extended spectrum beta-lactamase genes (ESBL) were confirmed in 65/138 (47%) 3GCR-Enterobacterales. Most common ESBL genes were blaCTX-M-15 (34/94, 36%) and blaSHV-12 (10/94, 11%). There were 48 deaths overall and 30-day in-hospital mortality was 3% (32/931). Infections with 3GCR Enterobacterales were independently associated with higher mortality (adjusted OR 3.2, 95%CI 1.6-6.4). CONCLUSION: GNBSI in children are frequently healthcare-associated and affect children under 5 years. Infections with 3GCR Enterobacterales were associated with worse outcomes. These findings will inform optimal management guidelines and help prioritise future antimicrobial clinical trials.

Antimicrobial use and appropriateness in neutropenic fever: a study of the Hospital National Antimicrobial Prescribing Survey data.

BACKGROUND: Neutropenic fever (NF) is a common complication in patients receiving chemotherapy. Judicious antimicrobial use is paramount to minimize morbidity and mortality and to avoid antimicrobial-related harms. OBJECTIVES: To use an Australian national dataset of antimicrobial prescriptions for the treatment of NF to describe antimicrobial use, prescription guideline compliance and appropriateness; and to compare these findings across different healthcare settings and patient demographics. We also aimed to identify trends and practice changes over time. METHODS: Data were extracted from the Hospital National Antimicrobial Prescribing Survey (Hospital NAPS) database from August 2013 to May 2022. Antimicrobial prescriptions with a NF indication were analysed for antimicrobial use, guideline compliance and appropriateness according to the Hospital NAPS methodology. Demographic factors, hospital classifications and disease characteristics were compared. RESULTS: A total of 2887 (n = 2441 adults, n = 441 paediatric) NF prescriptions from 254 health facilities were included. Piperacillin-tazobactam was the most prescribed antimicrobial. Overall, 87.4% of prescriptions were appropriate. Piperacillin-tazobactam and cefepime had the highest appropriateness though incorrect piperacillin-tazobactam dosing was observed. Lower appropriateness was identified for meropenem, vancomycin, and gentamicin prescribing particularly in the private hospital and paediatric cohorts. The most common reasons for inappropriate prescribing were spectrum too broad, incorrect dosing or frequency, and incorrect duration. CONCLUSIONS: This study provides insights into antimicrobial prescribing practices for NF in Australia. We have identified three key areas for improvement: piperacillin-tazobactam dosing, paediatric NF prescribing and private hospital NF prescribing. Findings from this study will inform the updated Australian and New Zealand consensus guidelines for the management of neutropenic fever in patients with cancer.

Invasive fungal disease in children with solid tumors: An Australian multicenter 10-year review.

Invasive fungal disease (IFD) occurs less frequently during treatment for solid compared to hematological malignancies in children, and risk groups are poorly defined. Retrospective national multicenter cohort data (2004-2013) were analyzed to document prevalence, clinical characteristics, and microbiology of IFD. Amongst 2067 children treated for solid malignancy, IFD prevalence was 1.9% overall and 1.4% for proven/probable IFD. Of all IFD episodes, 42.5% occurred in patients with neuroblastoma (prevalence 7.0%). Candida species comprised 54.8% of implicated pathogens in proven/probable IFD. In children with solid tumors, IFD is rare, and predominantly caused by yeasts.Routine prophylaxis may not be warranted.

An analysis of the resource use and costs of febrile neutropenia events in pediatric cancer patients in Australia.

BACKGROUND: Febrile neutropenia (FN) in children with cancer generally requires in-hospital care, but low-risk patients may be successfully managed in an outpatient setting, potentially reducing the overall healthcare costs. Updated data on the costs of FN care are lacking. METHODS: A bottom-up microcosting analysis was conducted from the healthcare system perspective using data collected alongside the Australian PICNICC (Predicting Infectious Complications of Neutropenic sepsis In Children with Cancer) study. Inpatient costs were accessed from hospital administrative records and outpatient costs from Medicare data. Costs were stratified by risk status (low/high risk) according to the PICNICC criteria. Estimated mean costs were obtained through bootstrapping and using a linear model to account for multiple events across individuals and other clinical factors that may impact costs. RESULTS: The total costs of FN care were significantly higher for FN events classified as high-risk ($17,827, 95% confidence interval [CI]: $17,193-$18,461) compared to low-risk ($10,574, 95% CI: $9818-$11,330). In-hospital costs were significantly higher for high-risk compared to low-risk events, despite no differences in the cost structure, mean cost per day, and pattern of resource use. Hospital length of stay (LOS) was the only modifiable factor significantly associated with total costs of care. Excluding antineoplastics, antimicrobials are the most commonly used medications in the inpatient and outpatient setting for the overall period of analysis. CONCLUSION: The FN costs are driven by in-hospital admission and LOS. This suggests that the outpatient management of low-risk patients is likely to reduce the in-hospital cost of treating an FN event. Further research will determine if shifting the cost to the outpatient setting remains cost-effective overall.

Density of antibiotic use and infectious complications in pediatric allogeneic hematopoietic cell transplantation.

BACKGROUND: Antibiotics, while an essential component of supportive care in allogeneic hematopoietic cell transplantation (allo-HCT), can have adverse effects and select for antibiotic resistance. Understanding of patterns of use will inform antimicrobial stewardship (AMS) interventions. METHODS: Retrospective, single-center cohort of children undergoing first allo-HCT (n = 125). Antibiotic prescription and infection data were included from the date conditioning was commenced until 30 days post allo-HCT. Antibiotic use was reported as length of therapy (LOT) (number of days a patient received an antibiotic) and days of therapy DOT (aggregating all antibiotics prescribed per day). Infections were classified as microbiologically documented infection (MDI) or clinically documented infections. RESULTS: At least one course of antibiotics was administered to 124 (99%) patients. The LOT was 636 per 1000 patient days and DOT was 959 per 1000 patient days. The median duration of cumulative antibiotic exposure per patient was 24 days (interquartile range [IQR] 20-30 days). There were 131 days of fever per 1000 patient days with patients febrile for a median of 4 days (IQR 1-7 days). Piperacillin-tazobactam was used for 116 (94%) of patients with an LOT of 532 per 1000 patient days. A total of 119 MDI episodes occurred in 74 (59%) patients, including blood stream infection in 30 (24%) and a proven/probable invasive fungal infection in 4 (3%). CONCLUSION: Pediatric HCT patients receive prolonged courses of broad-spectrum antibiotics relative to the frequency of fever and bacterial infections. This study has identified opportunities for AMS intervention to improve outcomes for our HCT patients.

Infections in children following chimeric antigen receptor T-cell therapy for B-cell acute lymphoblastic leukemia.

BACKGROUND: CD19-directed chimeric antigen receptor T-cell (CAR-T) therapy is transforming care for pediatric patients with relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL). There are limited pediatric-specific data concerning the infection risks associated with CD19 CAR-T therapy and the adequacy of current antimicrobial prophylaxis guidelines for these patients. METHODS: We describe the antimicrobial prophylaxis used and the types of infectious occurring in the first 100 days following CAR-T therapy for relapsed or refractory B-cell ALL in children and adolescents (≤18 years) at our centre. RESULTS: Twenty-seven patients received their first CAR-T infusion (CTI) during the study period. Almost all patients (96%) had a comprehensive Infectious Diseases review prior to CTI, which informed a personalised prophylaxis or fever/sepsis plan in six (22%). Overall, six (22%) patients had one or more infections during the study period including five (19%, 0.9 per 100 days-at-risk) from days 0-30 and three (n = 20, 15%, 0.6 per 100 days-at-risk) from days 31-100. Bacterial blood stream infections were the most common type of infection encountered during both time periods, and one patient had probable pulmonary aspergillosis. There were no infection-related deaths. CONCLUSION: Our study contributes important information on the spectrum of infections encountered in pediatric patients with B-ALL post CAR-T therapy. Overall, the burden of infectious complications post CAR-T therapy in our cohort is lower than previously reported in the literature. Results suggest that our prophylaxis recommendations are effective in this population.

The Challenge of Diagnosing Invasive Pulmonary Aspergillosis in Children: A Review of Existing and Emerging Tools.

Invasive pulmonary aspergillosis remains a major cause of morbidity and mortality for immunocompromised children, particularly for patients with acute leukaemia and those undergoing haematopoietic stem cell transplantation. Timely diagnosis, using a combination of computed tomography (CT) imaging and microbiological testing, is key to improve prognosis, yet there are inherent challenges in this process. For CT imaging, changes in children are generally less specific than those reported in adults and recent data are limited. Respiratory sampling by either bronchoalveolar lavage or lung biopsy is recommended but is not always feasible in children, and serum biomarkers, including galactomannan, have important limitations. In this review we summarise the current paediatric data on available diagnostic tests for IPA and highlight key emerging diagnostic modalities with potential for future use.

Novel approaches to the prediction and diagnosis of pulmonary complications in the paediatric haematopoietic stem cell transplant patient.

PURPOSE OF REVIEW: Haematopoietic stem cell transplant (HSCT) remains the only curative treatment option for many children with relapsed leukaemia, primary immunodeficiencies and haemoglobinopathies. Unfortunately, infectious and noninfectious pulmonary complications following HSCT continue to cause significant morbidity and mortality. This review will focus on recent advances in the field that enhance clinically available diagnostic tools and the role of novel diagnostic techniques. RECENT FINDINGS: Research continues to highlight the role of standard diagnostic modalities, including imaging using computed topography chest and Fluorodeoxyglucose-positron emission tomography (FDG-PET) in the diagnosis of posttransplant pulmonary infections. Similarly, bronchoalveolar lavage using bronchoscopy to obtain samples for microbiological analysis remains an important tool in the clinical and diagnostic algorithm for these children. The application of more novel diagnostic techniques such as metagenomic next-generation sequencing and the use of specific biomarkers remain potential future tools in children in whom the aetiology of posttransplant lung disease is unknown. The impact of the pulmonary microbiome on infectious and noninfectious pulmonary disease post HSCT is a future research direction. SUMMARY: Pulmonary infectious complications post HSCT remain a devastating complication for children and their families. Despite improvements in standard and novel diagnostic modalities, the aetiology of pulmonary disease remains unknown for many patients. There is an urgent need for ongoing collaborative research to bridge this critical knowledge gap and lead to better patient outcomes.

Antifungal use in children with acute leukaemia: state of current evidence and directions for future research.

Invasive fungal disease (IFD) remains a common and serious complication in children treated for leukaemia. Antifungal prescription in children with leukaemia presents unique challenges, particularly due to variation in IFD risk between and within leukaemia treatment protocols, drug toxicities and interactions between antifungals and chemotherapeutic agents. With recent advances in the understanding of IFD epidemiology and large clinical trials in adults assessing antifungals for IFD treatment and prophylaxis, together with paediatric clinical and pharmacokinetic studies, there is a growing body of data to inform optimal antifungal use in children. A panel of infectious diseases and haematology-oncology clinicians with expertise in IFD management compiled a list of 10 key clinical questions following development of the 2021 Australia and New Zealand Mycology Antifungal Consensus Guidelines. A focused literature review was conducted to explore available evidence and identify gaps in knowledge to direct future research. With the changing epidemiology of IFD globally, the ongoing evolution of paediatric leukaemia treatment and the increasing availability of novel antifungal agents, advocacy for paediatric clinical studies will remain vital to optimize IFD prevention and treatment in children with leukaemia.

Non-neutropenic fever in children with cancer: Management, outcomes and clinical decision rule validation.

INTRODUCTION: Fever and infection are an important complication of childhood cancer therapy. Most research and guideline development has focussed on febrile neutropenia, with a paucity directed at non-neutropenic fever (NNF). We describe the clinical presentation, management and outcomes of NNF in children with cancer, and externally validate the Esbenshade Vanderbilt (EsVan) clinical decision rules (CDR) to predict bacteraemia. METHOD: Using a prospective database, retrospective data were collected on consecutive NNF episodes (fever ≥38.0°C and absolute neutrophil count >1.0 cells/mm3 ). Sensitivity, specificity and area under the receiver operator characteristic curve (AUC-ROC) of the CDR were compared to derivation study. RESULTS: There were 203 NNF episodes occurring in 125 patients. Severe sepsis was uncommon (n = 2, 1%) and bacteraemia occurred in 10 (4.9%, 95% confidence interval [CI]: 2.7%-8.8%) episodes. A confirmed or presumed bacterial infection requiring antibiotics occurred in 31 (15%) patients. Total 202 (99%) episodes received at least one dose of intravenous broad-spectrum antibiotic and 141 (70%) episodes were admitted to hospital. Six (3%) episodes required intensive care unit (ICU)-level care and there were no infection-related deaths. The EsVan 1 rule had an AUC-ROC of 0.67, 80% were identified as low risk, and sensitivity and specificity were 50% and 81.5%, respectively, for a risk threshold of 10%. CONCLUSIONS: Serious infection and adverse outcome are uncommon in children with NNF. Many children did not have a bacterial cause of infection identified, but were still treated with broad-spectrum antibiotics and admitted to hospital. National clinical practice guidelines should be developed for this important cohort to enable risk stratification and optimise antibiotic management. Further research is required to determine appropriateness of EsVan CDR in our cohort.

Cost-effectiveness of home-based care of febrile neutropenia in children with cancer.

INTRODUCTION: Home-based treatment of febrile neutropenia (FN) in children with cancer with oral or intravenous antibiotics is safe and effective. There are limited data on the economic impact of this model of care. We evaluated the cost-effectiveness of implementing an FN programme, incorporating home-based intravenous antibiotics for carefully selected patients, in a tertiary paediatric hospital. METHODS: A decision analytic model was constructed to compare costs and outcomes of the home-based FN programme, with usual in-hospital treatment with intravenous antibiotics. The programme included a clinical decision rule to stratify patients by risk for severe infection and home-based eligibility criteria using disease, chemotherapy and patient-level factors. Health outcomes (quality of life) and probabilities of FN risk classification and home-based eligibility were based on prospectively collected data between 2017 and 2019. Patient-level costs were extracted from hospital administrative records. Cost-effectiveness was expressed as the incremental cost per quality-adjusted life year (QALY). FINDINGS: The mean health care cost of home-based FN treatment in low-risk patients was Australian dollars (A$) 7765 per patient compared to A$20,396 for in-hospital treatment (mean difference A$12,632 [95% CI: 12,496-12,767]). Overall, the home-based FN programme was the dominant strategy, being more effective (0.0011 QALY [95% CI: 0.0011-0.0012]) and less costly. Results of the model were most sensitive to proportion of children eligible for home-based care programme. CONCLUSION: Compared to in-hospital FN care, the home-based FN programme is cost-effective, with savings arising from cheaper cost of caring for children at home. These savings could increase as more patients eligible for home-based care are included in the programme.

Invasive fungal disease in children with acute myeloid leukaemia: An Australian multicentre 10-year review.

BACKGROUND: Invasive fungal disease (IFD) is a common and important complication in children with acute myeloid leukaemia (AML). We describe the epidemiology of IFD in a large multicentre cohort of children with AML. METHODS: As part of the retrospective multicentre cohort TERIFIC (The Epidemiology and Risk factors for Invasive Fungal Infections in immunocompromised Children) study, proven/probable/possible IFD episodes occurring in children with primary or relapsed/refractory AML from 2003 to 2014 were analysed. Crude IFD prevalence, clinical characteristics, microbiology and treatment were assessed. Kaplan-Meier survival analysis was used to estimate 6-month survival. RESULTS: There were 66 IFD episodes diagnosed in 63 children with AML. The majority (75.8%) of episodes occurred in the context of primary AML therapy. During primary AML therapy, the overall prevalence was 20.7% (95% CI 15.7%-26.5%) for proven/probable/possible IFD and 10.3% (95% CI 6.7%-15.0%) for proven/probable IFD. Of primary AML patients, 8.2% had IFD diagnosed during the first cycle of chemotherapy. Amongst pathogens implicated in proven/probable IFD episodes, 74.4% were moulds, over a third (37.9%) of which were non-Aspergillus spp. Antifungal prophylaxis preceded 89.4% of IFD episodes, most commonly using fluconazole (50% of IFD episodes). All-cause mortality at 6 months from IFD diagnosis was 16.7% with IFD-related mortality of 7.6% (all in cases of proven IFD). CONCLUSIONS: IFD is a common and serious complication during paediatric AML therapy. Mould infections, including non-Aspergillus spp. predominated in this cohort. A systematic approach to the identification of patients at risk, and a targeted prevention strategy for IFD is needed.

Home-based care of low-risk febrile neutropenia in children-an implementation study in a tertiary paediatric hospital.

BACKGROUND: Home-based management of low-risk febrile neutropenia (FN) is safe, improves quality of life and reduces healthcare expenditure. A formal low-risk paediatric program has not been implemented in Australia. We aimed to describe the implementation process and evaluate the clinical impact. METHOD: This prospective study incorporated three phases: implementation, intervention and evaluation. A low-risk FN implementation toolkit was developed, including a care-pathway, patient information, home-based assessment and educational resources. The program had executive-level endorsement, a multidisciplinary committee and a nurse specialist. Children with cancer and low-risk FN were eligible to be transferred home with a nurse visiting daily after an overnight period of observation for intravenous antibiotics. Low-risk patients were identified using a validated decision rule, and suitability for home-based care was determined using disease, chemotherapy and patient-level criteria. Plan-Do-Study-Act methodology was used to evaluate clinical impact and safety. RESULTS: Over 18 months, 292 children with FN were screened: 132 (45%) were low-risk and 63 (22%) were transferred to home-based care. Compared with pre-implementation there was a significant reduction in in-hospital median LOS (4.0 to 1.5 days, p < 0.001) and 291 in-hospital bed days were saved. Eight (13%) patients needed readmission and there were no adverse outcomes. A key barrier was timely screening of all patients and program improvements, including utilising the electronic medical record for patient identification, are planned. CONCLUSION: This program significantly reduces in-hospital LOS for children with low-risk FN. Ongoing evaluation will inform sustainability, identify areas for improvement and support national scale-up of the program.

Consensus guidelines for antifungal prophylaxis in haematological malignancy and haemopoietic stem cell transplantation, 2021.

Antifungal prophylaxis can reduce morbidity and mortality from invasive fungal disease (IFD). However, its use needs to be optimised and appropriately targeted to patients at highest risk to derive the most benefit. In addition to established risks for IFD, considerable recent progress in the treatment of malignancies has resulted in the development of new 'at-risk' groups. The changing epidemiology of IFD and emergence of drug resistance continue to impact choice of prophylaxis, highlighting the importance of active surveillance and knowledge of local epidemiology. These guidelines aim to highlight emerging risk groups and review the evidence and limitations around new formulations of established agents and new antifungal drugs. It provides recommendations around use and choice of antifungal prophylaxis, discusses the potential impact of the changing epidemiology of IFD and emergence of drug resistance, and future directions for risk stratification to assist optimal management of highly vulnerable patients.

Managing low-risk febrile neutropenia in children in the time of COVID-19: What matters to parents and clinicians.

AIM: The Australian 'There is no place like home' project is implementing a paediatric low-risk febrile neutropenia (FN) programme across eight paediatric hospitals. We sought to identify the impact of the coronavirus disease 2019 (COVID-19) pandemic on programme implementation. METHODS: Paediatric oncology, infectious diseases and emergency medicine health-care workers and parent/carers were surveyed to explore the impact of the COVID-19 pandemic on home-based FN care. Online surveys were distributed nationally to health-care workers involved in care of children with FN and to parents or carers of children with cancer. RESULTS: Surveys were completed by 78 health-care workers and 32 parents/carers. Overall, 95% of health-care workers had confidence in the safety of home-based FN care, with 35% reporting changes at their own hospitals in response to the pandemic that made them more comfortable with this model. Compared to pre-pandemic, >50% of parent/carers were now more worried about attending the hospital with their child and >80% were interested in receiving home-based FN care. Among both groups, increased telehealth access and acceptance of home-based care, improved patient quality of life and reduced risk of nosocomial infection were identified as programme enablers, while re-direction of resources due to COVID-19 and challenges in implementing change during a crisis were potential barriers. CONCLUSION: There is strong clinician and parent/carer support for home-based management of low-risk FN across Australia. Changes made to the delivery of cancer care in response to the pandemic have generally increased acceptance for home-based treatments and opportunities exist to leverage these to refine the low-risk FN programme.

Guideline for Antibacterial Prophylaxis Administration in Pediatric Cancer and Hematopoietic Stem Cell Transplantation.

BACKGROUND: Bacteremia and other invasive bacterial infections are common among children with cancer receiving intensive chemotherapy and in pediatric recipients of hematopoietic stem cell transplantation (HSCT). Systemic antibacterial prophylaxis is one approach that can be used to reduce the risk of these infections. Our purpose was to develop a clinical practice guideline (CPG) for systemic antibacterial prophylaxis administration in pediatric patients with cancer and those undergoing HSCT. METHODS: An international and multidisciplinary panel was convened with representation from pediatric hematology/oncology and HSCT, pediatric infectious diseases (including antibiotic stewardship), nursing, pharmacy, a patient advocate, and a CPG methodologist. The panel used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to generate recommendations based on the results of a systematic review of the literature. RESULTS: The systematic review identified 114 eligible randomized trials of antibiotic prophylaxis. The panel made a weak recommendation for systemic antibacterial prophylaxis for children receiving intensive chemotherapy for acute myeloid leukemia and relapsed acute lymphoblastic leukemia (ALL). Weak recommendations against the routine use of systemic antibacterial prophylaxis were made for children undergoing induction chemotherapy for ALL, autologous HSCT and allogeneic HSCT. A strong recommendation against its routine use was made for children whose therapy is not expected to result in prolonged severe neutropenia. If used, prophylaxis with levofloxacin was recommended during severe neutropenia. CONCLUSIONS: We present a CPG for systemic antibacterial prophylaxis administration in pediatric cancer and HSCT patients. Future research should evaluate the long-term effectiveness and adverse effects of prophylaxis.

Guidance regarding COVID-19 for survivors of childhood, adolescent, and young adult cancer: A statement from the International Late Effects of Childhood Cancer Guideline Harmonization Group.

Childhood, adolescent, and young adult (CAYA) cancer survivors may be at risk for a severe course of COVID-19. Little is known about the clinical course of COVID-19 in CAYA cancer survivors, or if additional preventive measures are warranted. We established a working group within the International Late Effects of Childhood Cancer Guideline Harmonization Group (IGHG) to summarize existing evidence and worldwide recommendations regarding evidence about factors/conditions associated with risk for a severe course of COVID-19 in CAYA cancer survivors, and to develop a consensus statement to provide guidance for healthcare practitioners and CAYA cancer survivors regarding COVID-19.

Managing haematology and oncology patients during the COVID-19 pandemic: interim consensus guidance.

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. ENDORSED BY: Australasian Leukaemia and Lymphoma Group; Australasian Lung Cancer Trials Group; Australian and New Zealand Children's Haematology/Oncology Group; Australia and New Zealand Society of Palliative Medicine; Australasian Society for Infectious Diseases; Bone Marrow Transplantation Society of Australia and New Zealand; Cancer Council Australia; Cancer Nurses Society of Australia; Cancer Society of New Zealand; Clinical Oncology Society of Australia; Haematology Society of Australia and New Zealand; National Centre for Infections in Cancer; New Zealand Cancer Control Agency; New Zealand Society for Oncology; and Palliative Care Australia.

Nonneutropenic fever in children with cancer: A scoping review of management and outcome.

To date, very few studies have addressed nonneutropenic fever (NNF) in children with cancer, and there are no consensus guidelines. This scoping review aims to describe the rate of bacteremia, risk factors for infection and management, and outcomes of NNF in this population. Across 15 studies (n = 4106 episodes), the pooled-average bacteremia rate was 8.2%, and risk factors included tunneled external central venous catheter, clinical instability, and higher temperature. In two studies, antibiotics were successfully withheld in a subset of low-risk patients. Overall outcomes of NNF appear favorable; however, further research is required to determine its true clinical and economic impact.

Invasive fungal infections in children with acute lymphoblastic leukaemia: Results from four Australian centres, 2003-2013.

BACKGROUND: Invasive fungal infections (IFI) are an important complication of acute lymphoblastic leukaemia (ALL) treatment. Our study describes the prevalence and outcomes of IFI in children with ALL. METHODS: IFI episodes in children with primary or relapsed ALL, identified for The Epidemiology and Risk Factors for Invasive Fungal Infections in Immunocompromised Children study, were analysed. IFI were classified according to European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group criteria with a 'modified-possible' category included. RESULTS: A total of 123 IFI episodes in 119 patients with ALL were included. A proven, probable, possible and modified-possible IFI was diagnosed in 56 (45.5%), 22 (17.9%), 39 (31.7%) and six (4.9%) episodes, respectively. The prevalence was 9.7% (95% confidence interval [CI] 8-11.4%) overall and 23.5% (95% CI 14.5-32.5%) for relapsed/refractory ALL. For non-relapsed ALL, the IFI prevalence was significantly higher for children with high-risk compared to standard-risk ALL (14.5% vs 7.3%, P = .009), and IFI were more common during induction, consolidation and delayed intensification phases. Mould infections occurred more frequently than non-mould infections. Thirteen children (10.9%) died within 6 months of IFI diagnosis with five deaths (4.2%) attributable to an IFI. CONCLUSIONS: IFI is more common in children with high-risk ALL and in relapsed disease. Overall survival was encouraging, with IFI contributing to very few deaths.
