General Internal Medicine

Research Overview

The General Medicine Research Group, headed by Professor Edward Janus (Head of General Medicine and Western Health’s Director of Office for Research) and Associate Professor Harin Karunajeewa (Divisional Director, Research) aims to develop clinical and health services research that is closely aligned to the areas of greatest burden to hospital services at Western Health. This therefore emphasizes particular issues relating to migrant groups and elderly patients with high rates of multi-morbidity.

We aim to incorporate training and mentorship of our physician trainees into our research program with our overarching objective of being clearly acknowledged as the leading academic General Internal Medicine Unit in Australia within the next 3 years.

We leverage Professor Janus’ existing track record and collaborative links in diabetes, atherosclerotic disease, cardiology and other chronic diseases. We also leverage A Prof Karunajeewa’s interest in infectious diseases, particularly through his co-appointment at the Walter and Eliza Hall Institute of Medical Research (Division of Population and Immunity) and international collaborative links. These create opportunities we hope to exploit to link state of the art biomedical research at WEHI with our clinical research activities. These have included or will include new diagnostics techniques for therapeutic monitoring in tuberculosis and applying microbiomics, transcriptomics and genomics to evaluations of acute respiratory infections.

A new area of research for our group is health services research and health economics. This reflects Western Health’s broader organizational strategy of building capacity in this field and we hope this will see us well placed to capitalize future opportunities that will arise as the Australian research funding environment comes to place increasing emphasis on translational research that generates efficiency dividends for government. Given our existing emphasis on high hospitalization burden conditions and in infectious diseases, these preliminary studies and associated publications have concentrated on areas such as acute respiratory infection (community acquired pneumonia), diabetes and cellulitis (infection of skin). This work has seen us develop expertise in data linkage using existing hospital data sources, utilization of clinical costing data for health economic analyses and a successful funding application from the HCF research foundation to evaluate a new service delivery model for treating community acquired pneumonia.
