Description of intervention(s) / exposure
In part 1 of of this study, the aim is to prospectively validate nine clinical decision rules (CDRs) including the European-based PICNICC CDR, that stratify children with cancer and febrile neutropenia into low and high risk for microbiologically documented infection (MDI), so as to optimise their management and quality of life and improve resource allocation. The PICNICC CDR is based on five simple clinical variables including (i) tumour type (ii) maximum temperature, (iii) total white cell count, (iv) monocyte count, (v) haemoglobin and (vi) severity of illness. It provides the opportunity for a world first external validation of this globally derived rule and is a critical step before the rule can be safely implemented into practice.

In Part 1 and 2 of the study, patient demographic, FN episode and outcome data at day 0, completion of the FN episode and day 30 will be collected prospectively by the study-site research assistant/nurse (RA/RN) according to international consensus definitions. Patients that develop FN outside of RA/RN working hours will have relevant data collected retrospectively within 72 hours. Data will be entered into an electronic password protected study database (REDCap). Accuracy of data collection will be verified by project manager (first ten records for each site then periodically throughout recruitment) as well as chief investigator and site associate investigator.

For patient recruited only in part 1 of this study, novel biomarkers that predict outcomes will be identified using RNA sequencing (RNAseq) analysis on peripheral blood mononuclear cells (PBMC) collected from participants at Royal Children's Hospital Melbourne at two time points. Blood will be collected in EDTA tubes (5ml if <40kg and 12ml if >40kg). Peripheral blood samples will be processed by the Children’s Cancer Centre Tissue Bank. Within two hours of sample collection, plasma will be harvested following centrifugation and stored at -80 degrees celsius. PBMCs will be isolated by Ficoll density gradient centrifugation. PBMC will be cryopreserved and stored in the vapor phase of liquid nitrogen for in vitro assays and pelleted and resuspended in RNAlater for nucleic acid extraction. Samples will be batched and distributed by the CCC Tissue Bank.

RNAseq will be performed at MCRI (25-30 M coverage) on unstimulated and stimulated samples. Additionally PBMCs will be analysed by flow cytometry to determine the frequency of T cells, and monocytes. This latter data set will allow bioinformatic deconvolution to dissect the transcriptome of relevant cell types. When we have established which method (stimulated or unstimulated) provides that most robust data we will proceed to collect and analyses 100-200 samples . Flow cytometry and stimulation of PBMCs will be performed in the Pellegrini laboratory at the Walter and Eliza Hall Institute of Medical Research. The cell samples sent to WEHI will be thawed and placed in culture medium. During the pilot study these samples will be unstimulated or stimulated with agents that are known to amplify immune responses for a few hours. The medium the cells were kept in will then be collected, to be analysed upon completion of transcriptome analysis for secreted immunogenic factors. The cells themselves will be labelled with specific antibodies which will distinguish the individual cells into subtypes of immune cells and their activation status. During this process all the cells will be run on a machine to analyse composition. Therefore no cells will remain after the analysis has taken place. However, the culture medium these cells were kept in will be stored indefinitely at -80 degrees celsius in the secure Pellegrini laboratory freezer. RNA sequencing is being carried out to identify biomarkers that can predict the outcome of FN episodes only. The transcriptome analysis performed as part of this study is purely exploratory. None of the tests being performed are validated or accredited as diagnostics. Therefore no information will be revealed about disease-predisposing germline traits, heritable disorders or parental identity.

To investigate the cost of patient in hospital versus patients managed at home, all consented patients will be reviewed for their cost information using hospital costs records for inpatient data and outpatient costs via the Medicare consent form, completed at patient recruitment by the RA.

The optional quality of life surveys have been replicated into an electronic format for consented parents/guardians and patients older than three years, The age ranges for the CHU-9D assessment (7 to 18 years and a proxy version for patients aged 3 to 6 years) have been stipulated by the University of Sheffield and will be adhered to when implementing the questionnaire. The RA will implement each tool electronically prior to discharge, providing education on how to complete the surveys. To provide a comprehensive overview of the true impact of FN and unplanned hospital admission on the child. For patients that have been discharged home, the surveys will be distributed electronically, via RedCAP, to valid email address.

In part 2 of the study, we will be evaluating the implementation process and the clinical, quality of life and economic impact of the low risk FN program across 8 hospitals in Australia. The Consolidated Framework for Implementation Research (CIFR) will be used (https://cfirguide.org/) to guide implementation and evaluation. This will be completed as a survey by the healthcare professionals. In addition, each site will have regular focus group meetings to review implementation processes for each site. Outcomes from these meetings will be reported back to the central management team for their review and consideration.

In summary, low risk febrile neutropenia patients will continued to be recruited as per Part 1, with the same frequency/duration of participation. The focus for Part 2 of the study will be on the hospitals and healthcare professionals implementing the low risk febrile neutropenia program at their site. Furthermore, we will continue to obtain Medicare data from patients to evaluate cost of patients at home versus patients staying in hospital.

Statistical methods / analysis
International data indicate that microbiologically documented infection occurs in between 18 and 25% of episodes of febrile neutropenia. This is supported by local pilot data at Monash Children’s Hospital and Royal Children’s Hospital. For validation of the PICNICC clinical decision rule (Objective 1), 780 episodes of febrile neutropenia, with an estimated event rate of 18%, are required for 80% power to show AUC-ROC of the PICNICC model is greater than or equal to 0.7. Accounting for a 10% dropout the target for recruitment is 848 across the 8 study sites.

The sample size for the biomarker study (Objective 2) will be calculated from an exploratory study. The bioinformatics department at the Walter and Eliza Hall Institute (WEHI) will perform power calculations in the preliminary data to ascertain a sufficient sample size. Based on their experience 100-200 participants with 200-400 samples should provide adequate data for correlative analyses.

Quality of life (QoL) will be reported using the descriptive systems and as the mean utility values derived using the standard algorithms for each instrument (Objective 3). These will be reported for children, and their parents/guardians, with and without an MDI and those classified as high and low risk, and taking into account the impact of key demographic factors on QoL (such as age, gender, income and educational status). The implications of MDI for quality adjusted survival will be explored using modelling approach to combine the observed utility values with patient survival.

Economic data will be reported as total cost and the cost per day of admission and episodes with and without an MDI and those classified as high and low risk will be compared. Mean estimates of costs will be used and confidence intervals will be generated by boot-strapping the data. Results will be presented as a cost-consequence analysis in terms of the mean costs and quality of life effects (expressed as utility values) associated with and without an MDI event.

Implementation evaluation (Objective 4) will be an ongoing iterative process to identify any new barriers arise through the implementation process. Post implementation clinical, economic and QoL data for episodes identified as low risk will be compared to pre-implementation data from part of of this study and matched according to risk status. Continuous data will be presented as median and interquartile range. Mann–Whitney U test was used to estimate P-values for continuous data and Fisher’s exact test for categorical data. P-value <0.05 will be considered statistically significant. Qualitative data from post-implementation focus group meetings will be grouped according to theme and paired with corresponding solutions or changes to the program. Where appropriate, impact of individual changes will be done by comparing patient enrollment pre and post-program change.

The costs and outcomes for the low-risk FN program will be presented as a cost-consequence analysis to show the relative impact on costs and QoL outcomes of the two treatment programs (ie. hospital and home-based care). The data will also be combined in a modelled analysis to assess the average expected cost-effectiveness (cost per quality-adjusted-life-year) in patients with low-risk FN comparing hospital and home-based management. A modelled analysis will be used to account for the potential longer-term impacts on costs and outcomes of the alternatives approaches to low-risk FN management. Overall, confidence intervals around the costs and outcomes will be generated by bootstrapping the data, and the robustness of the analysis explored using sensitivity analysis.
