All children received a clinical diagnosis at the MNRH, based on information on presentation and physical findings on clinical examination.
In some patients, notes had been destroyed prior to the beginning of this study and information on presentation and cause of death was sought from relatives and death certificates.
Birth Certificates include demographic data of the mother, information on presentation and multiple pregnancy (singleton cephalic, singleton breech, trasverse or oblique lie, etc)., parity (nulliparous, multiparous), the course of labour and delivery (spontaneous labour, induced labour or CS before labour) and gestational age (defined as the number of completed weeks at the time of birth).
The present report includes all patients (≥18 years) newly diagnosed with denovo DLBCL (n = 2137) between 1st September 2004 and 31st August 2012; all of whom were followed-up until the 6th February 2015, with primary source information on presentation, treatment and management including chemotherapy regimen being obtained directly from medical records.
We restricted our analysis of ED presentations to decedents from the "Greater Sydney Area" as we believe there is sufficiently complete information on their presentations to EDs.
Please see the document library and roundtable themes for more information on the presentations, working papers, and conclusions and recommendations.
The system draws on real time, continuously updated information on ED presentations, including the coded primary diagnosis, from all public hospitals across Perth.
On the other hand, most published "real-world" studies of cSSTIs are based on retrospective data sources which often do not provide detailed information on patient presentations, approaches to treatment or clinical outcomes [ 14, 15].
Ideally, we would also have wanted information on all presentations of acute respiratory illness, with additional information on the recorded temperature, and not just FRI; however, this would have increased the complexity of data collection, and we therefore adopted the compromise of using just febrile respiratory illness as our case definition for identifying possible pdmH1N1 infections.
