Predicting infectious complications in neutropenic children and young people with cancer (IPD protocol)

<p>Abstract</p> <p>Background</p> <p>A common and potentially life-threatening complication of the treatment of childhood cancer is infection, which frequently presents as fever with neutropenia. The standard management of such episodes is the extensive use of intravenous antibiotics, and though it produces excellent survival rates of over 95%, it greatly inconveniences the three-fourths of patients who do not require such aggressive treatment. There have been a number of studies which have aimed to develop risk prediction models to stratify treatment. Individual participant data (IPD) meta-analysis in therapeutic studies has been developed to improve the precision and reliability of answers to questions of treatment effect and recently have been suggested to be used to answer questions regarding prognosis and diagnosis to gain greater power from the frequently small individual studies.</p> <p>Design</p> <p>In the IPD protocol, we will collect and synthesise IPD from multiple studies and examine the outcomes of episodes of febrile neutropenia as a consequence of their treatment for malignant disease. We will develop and evaluate a risk stratification model using hierarchical regression models to stratify patients by their risk of experiencing adverse outcomes during an episode. We will also explore specific practical and methodological issues regarding adaptation of established techniques of IPD meta-analysis of interventions for use in synthesising evidence derived from IPD from multiple studies for use in predictive modelling contexts.</p> <p>Discussion</p> <p>Our aim in using this model is to define a group of individuals at low risk for febrile neutropenia who might be treated with reduced intensity or duration of antibiotic therapy and so reduce the inconvenience and cost of these episodes, as well as to define a group of patients at very high risk of complications who could be subject to more intensive therapies. The project will also help develop methods of IPD predictive modelling for use in future studies of risk prediction.</p

Management of febrile neutropenia in pediatric oncology across Queensland, Australia: a retrospective review on variations between locations

Febrile neutropenia (FN) is a common complication in pediatric oncology with intravenous antibiotics being given routinely for decades. This study aimed to compare the management of FN in children in different locations across Queensland, Australia. FN episodes were identified from 4 settings: tertiary oncology outpatient department (OD), tertiary emergency department (ED), regional ward (RW), and regional emergency department (RED) between July 2009 and June 2011. Retrospective data were extracted from medical records, collated, and then analyzed to identify differences in outcomes attributable to location. Sixty-one episodes of FN were reviewed: 5 cases from OD, 28 from ED, 19 from RW, and 5 from RED. Statistically significant differences occurred in the time taken for medical review for cases depending on location of presentation. Patients who presented to the ED or the RW were more likely to be seen within 30 minutes than in other locations (P = .014), and patients who presented to the tertiary hospital in either the OD or ED were more likely to commence antibiotics within 120 minutes of presentation (P = .023). Antibiotics were commenced within 60 minutes (the gold standard) on only 10 occasions. Despite education input emphasizing the importance of early commencement of antibiotics, this study identified that this objective was not met in the majority of cases. Further study is needed to look at reasons for the delay in beginning treatment for pediatric oncology patients in Queensland and what measures may assist with improving the time from presentation with FN to antibiotic administration across all settings
