Data for Decisions

We would like to say a huge thank you to all the practices that contribute their EMR data to the Data for Decisions research initiative. This data is used by researchers across Australia with the aim of developing interventions or tools that can help GPs and patients make informed decisions about optimising their health.

Patron data has continued to be used by the VCCC Data Connect team, linking PATRON data with the Victorian Cancer Registry and the Victorian Admitted Episodes Dataset, to be used for multiple studies.  One recently completed project titled ‘Patterns of diagnostic testing for OG cancer related symptoms including cost analysis of testing’, examined how general practitioners (GPs) investigate symptoms that may be related to oesophagogastric (OG) cancer, analysing data from 44,402 patients aged 55 and older who presented to general practices in Victoria between 2008 and 2022.  Although OG cancer is relatively uncommon, affecting only 0.28 percent of symptomatic patients within 12 months, the research identified significant inequities in diagnostic testing. Patients aged 75 and above were 40 percent less likely to be investigated, despite having a higher risk of cancer. Likewise, individuals from socioeconomically disadvantaged areas were much less likely to receive specialist referrals or endoscopy compared to those from more advantaged communities.

Investigation patterns varied considerably depending on the symptom. Nearly half of the patients who presented with weight loss or anaemia had no recorded investigation, representing potential missed opportunities for earlier diagnosis.

This work underscores the careful balance GPs must maintain between conducting thorough investigations and avoiding unnecessary testing. It also highlights the importance of ensuring that all patients receive equitable care, regardless of age or socioeconomic background.  This was published in the British Journal of General Practice in October 2025.

Without General Practice dedication to research and ongoing data contributions, this study would not have been possible.  Thank you!
